Dipper Pines was dressed in his usual gray shorts and black sneakers, but he’d foregone the reddish shirt and dark blue vest in favor of a green windbreaker. Also missing was his usual blue and white cap, leaving only twigs and bits of leaves in his bushy brown hair as he crouched under an evergreen.

He took a hard look around the woods on that calm, misty morning. He surveyed the tall, majestic old-growth trees and especially the thick undergrowth. Sunbeams sliced the canopy at sharp angles here and there, making it a little harder to see in places. Like his hiding spot. At the same time he strained to listen for any sounds of footsteps or vehicles, but on that calm early morning he could only hear early birds singing and the occasional rustle of small animals just waking up.

He suddenly stopped and let his eyes open fully. This has to be almost the most beautiful I’ve seen this place. Then he chuckled and shook his head a little, “Though not as beautiful as what I saw yesterday.”

The boy silenced himself as footsteps approached. They were accompanied by girlish laughter and small talk. Dipper pushed aside the leaves to see his tall red haired crush, Wendy Corduroy, and her friend Tambry walking towards the small clearing not ten feet away. It was covered mostly with moss and thick grass that had already dried. Besides Tambry’s ever-present cellphone and purse she was carrying a picnic blanket, which she shook out and laid in the sunny spot.

Wendy immediately dropped to her knees and kicked off her oversized boots. Then she gracefully rolled onto the blanket and landed on her back. She looked up at nothing in particular, smiling brightly. The brown-skinned girl was furiously tapping away on her cellphone yet somehow managed to find the edge of the blanket as she sat down. Then she paused for a second, never taking her eyes off the tiny screen while tossing her oversized purse behind herself. It nearly landed on Wendy’s face.

“Hey!” the taller girl laughed as she quickly got up on her knees. She opened the purse and pulled out a flask-shaped bottle, quickly unscrewing the top and taking a swig. Then she leaned over and playfully grabbed a handful of the purple hair off Tambry’s right shoulder, giving a few gentle tugs before starting to pull back for real. Tambry quickly powered off the phone and, as she was leaning back, tried to drop it in her purse but missed. Before she could reach for it Wendy had the girl cradled in her arms. After brushing aside the tress of shock pink over Tambry's face, Wendy placed the bottle against the other girl’s lips. The smaller girl didn’t hesitate to take a few sips before Wendy pulled it away and took another big gulp.

“Don’t hog it all!” Tambry laughed as she pretended to reach out for it, but Wendy just let go of her. “Eep!” she squeaked as she caught herself on her elbows. It sounded so cute that Dipper had to stifle a giggle. Now that the girls had settled in, he got down on his knees where he could see better.

Wendy ignored Tambry’s protests and took a big mouthful before dropping the bottle on the other end of the blanket. However, Dipper could see that her cheeks were puffed up. Wendy grabbed Tambry in both arms and kissed her, hard on the lips, then allowed Tambry to drink the booze from her mouth. As the tanned girl swallowed from the redhead’s lips, Wendy lowered her down onto the blanket and then let the last bit of rum drizzle out over the sides of Tambry’s mouth. She began to lick it off, slowly yet hungrily. Tambry wrapped her arms around Wendy and began kissing her cheeks too. They kissed a few times in earnest before Wendy moved to straddle her girlfriend’s legs. With one hand next to Tambry’s head for support, the tall girl resumed her passionate kisses while her free hand rubbed her lover’s belly, quickly slipping under the shirt and making it’s way up to Tambry’s soft, round breasts. Tambry gripped the back of Wendy’s head and kissed even harder while moaning. She lifted her tummy up long enough for the redhead to push her shirt up, revealing those two wonders.

Perhaps they were only around B-cups, but to the preteen boy they may as well have been mountains. After unbuckling and unzipping his pants he held a branch full of leaves to the side so he could see a little better. His other hand reached into his underpants and pulled out his quickly stiffening cock. He gave it a few placating rubs.

Wendy broke the kiss and roughly pulled the smaller girl’s shirt completely off. “Ow!” Tambry complained when the collar snapped her nose, but that didn’t break their rhythm. Wendy got on her knees and in a single motion arched her back to drop her flannel outer shirt off. Tambry pushed herself up on her elbows and tried to bite Wendy’s exposed belly, eliciting a loud squeal. Then the two giggled as the punk girl gripped the redhead’s hips and shoved her mouth into Wendy’s navel. The taller girl shuddered and hissed as Tambry’s tongue flicked and licked all around inside that tiny fold, sending sharp shockwaves through Wendy’s body. They were most noticeable in her groin, but it was more than arousing. It was mild torture to make Wendy hurry up and get her undershirt off. Wendy eagerly revealed two breasts sporting big areolas with matching pointy nipples. That done, Tambry gave her belly a kiss then quickly undid her friend’s belt and pants, eagerly pulling them halfway down her hips.

“Anxious, aren’t we?” Wendy teased.

“Hey, you’re the one who's gotta be at work soon!”

“I guess,” Wendy said while turning onto her back and taking her pants and underwear completely off. Now dressed only in her hunter’s cap, she turned her attention back to Tambry. She got on her hands and knees over the smaller girl’s stomach and deftly undid the button on her slacks. As she pulled them down she was pleasantly surprised to see that Tambry had gone commando, so the redhead didn’t waste any time in kissing the top of her vulva fully. She made sure to dip her tongue in and swish around Tambry’s very sensitive clit a few times, making her friend groan and tense up. Wendy laughed. After the payback was complete she pulled the slacks down around Tambry’s ankles and spread the girl’s knees. She crawled in-between and hovered over her friend while kissing her full on the mouth. Wendy grabbed and roughly handled one of Tambry’s breasts, eliciting loud grunts and moans of pleasure. The smaller girl gripped the back of Wendy’s head to make the kiss more forceful, and her other hand reached down straight to the target, coarsely stroking and fingering Wendy’s small but shapely mound.

Dipper was having a hard time keeping his breathing from getting too loud. Ever so cautiously, he shifted on his knees to get his pants down around his ankles. He knew that one false move, one loud noise, and he’d have no chance to escape before the girls caught him. And who knew what they would do to him? Tambry could have pictures of him struggling to pull his pants up sent to half the country in ten seconds flat. Or maybe Wendy would take a more physical approach to his punishment… His dick suddenly got so painfully hard that he had no choice but to stroke it slowly, easing the tension just barely enough.

Wendy’s head moved down to her friend’s breasts and was mouthing one vigorously, bobbing her head up and down as she nuzzled, kissed, sucked and even bit the beautiful little orb. Without stopping, she moved to the side and held Tambry’s shoulder down with one hand; the other slid down to her clit and petted it very gently. The redhead quickly pulled her hand up and looked at it. She grinned as she turned back to face Tambry, who had her own devilish smile. While they stared into each other’s eyes, Wendy brought her glistening fingers to her mouth and deliberately sucked them. Tambry opened her mouth and tried to lift herself up and lick them too, but Wendy held her firmly. After enjoying the girl’s pleading look for a few delicious moments, the redhead relented and moved in, face to face, so that Tambry could lick those fingers clean. They kissed again, for a good long minute, before Wendy backed down Tambry’s length. Dipper watched Tambry writhe and moan and shift as Wendy began eating her out with vigor. “Oh yeah! Oh please!” she pleaded. “Fuck yes! Oh yeah, make me cream all over your face!”

For a fleeting moment Dipper thought how weird it was that the most he ever heard Tambry speak was dirty talk. But as he began to stroke his dick more regularly he was happy to have their sounds covering his own.

“Fuck yeah, girl, get your pussy over here!” Tambry hissed. Wendy and Dipper laughed in unison.

Wendy backed off and let out several loud wet kisses as she asked, “What do you want?” Then she dove back in, nodding her head as she licked her friend’s slit up and down.

“I want you! Now!”

“I don’t know what you mean,” Wendy claimed innocently. Then she pressed her face hard into Tambry’s cunt. Dipper could even see her cheeks move as she tongue-fucked her friend silly. The smaller girl let out several sharp whines and gasps as Wendy shook her head violently, like a wolf tearing at its prey.

“I want your pussy on my face, bitch!”

Wendy instantly pulled back. “Then why didn’t you just say so?” she teased. Tambry grabbed the redhead’s hips with both hands and pulled as Wendy turned around.

The brown-skinned girl turned her palms out and pulled Wendy’s butt cheeks and sex wide open. And Dipper had a clear view of it all. He could even see wisps of the short red hairs that lined Wendy’s cunny.

“Come on,” Tambry whined impatiently. “Fuck my face with that gorgeous pussy of yours!” Wendy timed it perfectly so that her bottom pressed down on Tambry’s begging mouth just as her own lips resumed contact with her friend’s cunt. She rocked her hips back and forth slowly as Tambry did her best to suck and lick noisily, unable to suppress her own moans of extreme pleasure as Wendy eagerly kissed and sucked the top of her pussy. The redhead shoved two fingers up her friend’s sopping entrance and moved them in and out hard, making Tambry’s whole body buck as if she were having a seizure.

By now Dipper was rubbing himself in steady strokes and fondling his balls. His ragged breaths were louder than he would have liked, but the sounds of moans and gasps and wet tongues and fingers going in and out more than drowned him out.

Wendy stopped rocking and spread her knees farther apart, pressing down on Tambry’s face much harder. She began raising and lowering her pelvis quickly, just a bit, as Tambry clenched her fingers even harder on Wendy’s ass and doubled down on her efforts. The lewd sounds of her licks and smacks seemed to explode in the boy’s ears, breaking up Wendy’s languid moans. The redhead threw her head up and arched her back as she cried out, “Oh fuck! Yeah fuck that’s awehahahahha!” Her eyes closed and she went completely still. Her insides seized up tight and then relaxed for a split second before spasming repeatedly, and a fresh wave of juices drizzled out her snatch. Tambry slowed her efforts and just tenderly kissed all around her friend’s outer lips, licking her clean and occasionally nipping or kissing her pussy. Wendy quivered and grunted but was otherwise lost in a long, satisfying orgasm.

Finally Wendy rolled off her friend and onto her back, panting for dear life. Tambry stretched her stiff arms then turned onto her side. She cradled the redhead, holding Wendy’s face to her breasts while she was still caught up in the afterglow. Wendy slowly opened her eyes and looked up at Tambry’s face. And smiled. “Your turn,” she stated while landing a hard slap on the other girl’s ass. Tambry jumped to her feet, but only long enough to place her knees on either side of Wendy’s head, facing away from Wendy’s body so that she could look down into the redhead’s eyes. It also meant that she was facing Dipper. She kept her back straight as she slid to the side. Wendy grabbed Tambry’s hips and raised her head the rest of the way. She immediately went back to work, sucking and licking and slurping. Tambry put two fingers in her mouth and got them slick before reaching down to play with one of her erect nipples. Her other hand alternated between fondling her other breast and occasionally brushing Wendy’s hair out of her eyes. The redhead went at it with full force, making Tambry squirm in delight.

The view was too much for Dipper. He began stroking his cock harder, more roughly, even though he was scraping his skin a bit. It didn’t matter anymore – he just needed to get off more than anything. His breathing was hard and heavy, and he had a difficult time keeping his eyes open, but as soon as they started to close he’d miss that gorgeous view of Tambry and they’d pop back open. He took one long hard look as he furiously rubbed himself. Tambry’s moans and cries filled the air as she roughly played with her breasts and Wendy ate her out. Tambry’s eyes closed and opened slowly as her body swayed rhythmically.

Despite his best efforts Dipper let out a yelp and then when he looked back he saw Tambry’s eyes wide open. Does she see me? ran through his mind for only an instant as his balls were nearly sucked back into his body. His cock spasmed so hard he thought it would rip itself off his body like a rocket launching. His first squirt sent cum flying almost two feet, where it splattered on some ferns with a hard wet sound. It was barely audible, yet between his ecstasy and his fear it may as well have been thunder. The next blast felt even harder and landed just as noisily, but as the warmth and dizziness took over his body he stopped caring. Pleasant heat shot out from his groin and engulfed his entire body.

He fired off a few more loads of spunk just in front of himself, then fell on one hand as he gingerly shook his dick, milking out the last of it. It pulsed a few more times as Tambry let out a long guttural groan and gripped her breasts as hard as she could. Her eyes scrunched up as her chamber walls began throbbing with release and her body went flush with heat. Her head fell back and she sucked in a deep breath, holding it for a long moment then letting it out. Wendy quickly pulled herself out from under Tambry and got on her knees to wrap an arm around her from behind. She began kissing the side of Tambry’s face and neck while stroking her breasts and belly with her other hand. It quickly moved down to the punk girl’s snatch and she pistoned her middle finger in and out several times for good measure. Tambry grunted and winced, so Wendy put both arms around Tambry’s hips and laced her fingers over the girl’s belly. Tambry turned her head back and Wendy moved in to meet her. They shared a gentle, lingering kiss.

Now completely on his hands and knees, Dipper looked up to see while catching his breath. Then he looked down to see his penis was completely soft, but a thick strand of cum still ran from it to the ground, almost like a spider web. He shook it loose then got up on his knees. Tambry had turned around to face Wendy, so neither girl could see him. Reluctantly he wiped his sticky hand on some leaves then quickly pulled his pants back up. As he moved into a crouching position he could feel how stiff and spent his small body was, but somehow he managed to avoid snapping any twigs or rustling the bushes as he snuck away.

Wendy pulled away from their kiss and looked over Tambry’s shoulder. “Show’s over, but wow was it fun!” she laughed. After standing she helped Tambry up too and, still naked as the day is long, the two walked over to the boy’s hiding spot. Tambry sniffed the air then looked down to see the pool of cum on the leaves. Wendy noticed the fresh scrapes on the ground where Dipper had been on his knees. “Wow, he really got some distance,” she marveled.

“Yeah, and I wish I got a picture of his face when he saw me looking at him,” Tambry sighed dreamily. “Do we really have to do this to him? It’s kind of mean.”

“Don’t worry about him,” Wendy said while looking at the jizz on the leaves and the trail going back to his spot. “He’s definitely having a good time.”

Tambry wrapped one arm around Wendy’s neck and laid her head on her shoulder. “But he could be having an even better time,” she cooed.

“Yeah, but we’d get in big trouble if Stan found out,” Wendy sighed. “Speaking of which, I gotta get to work.”

Even while asleep Mabel was smiling brightly as she rolled over in Dipper’s bed. “I love you, Dipper,” she sighed before giving the pillow a big wet kiss. She suddenly stuck out her tongue. “Blech!” she cried as her eyes shot open, but then she giggled. “You’re not Dipper,” she told the pillow. “And after he begged me to get in bed with him last night, saying he’d read some Gerard mysteries with me.” Mabel sighed, disappointed. “And that’s all he did. Oh well, if he’s out,” she said loudly, “I know who else would love some big wet sloppy kisses!” She waited expectantly for a moment then crinkled her nose. “I said, ‘I know who else would love some kisses!’” she tried again, but the room stayed completely quiet. She sat up and looked around nervously. “Waddles? Where are you? Here boy!”

Nothing.

She disentangled herself from the blankets and sat up, bare chested and wearing only tiny pink and blue panties. She looked at the clock. 9:40 AM. “Hmm,” she said with disapproval. Mabel got up, stretched, making a point to turn and show her developing young chest to the entire room even though it was empty. She quickly threw on a tee shirt and a pair of jeans before skipping downstairs.

“Good morning, Grunkle Stan!” she called out to the empty store. She heard sounds from the kitchen so she bounded in to find the lovable heavy-set janitor at the stove. “Good morning, Soos! Have you seen…” She saw Waddles at the table, standing up on a chair as he munched away off a plate. Mabel’s eyes went wide with horror.

“You hungry? I got bacon, sausage, ham,” Soos said merrily as he turned and doled out more pork onto Waddles’ plate. “Wow, look at him go!” he laughed.

“What are you doing!” Mabel cried as she pulled her pig from his seat and clutched him tightly. Mabel tried to pull the strip of bacon from his mouth, but he squealed and hissed and nipped at her fingers.

“What?” Soos asked as he held out a piece of sausage to the pig. Waddles squealed and tried to jump for it, and Mabel had to struggle to keep him in her arms. “He really likes the stuff.”

“Soos, how could you! Don’t you know that pigs aren’t supposed to eat other pigs! Now that he’s tasted delicious piggy flesh he’ll be ostrichsized by all the others of his kind.” Mabel started sobbing into the wriggling pig’s neck.

“Gee, I’m sorry Mabel. I didn’t know. But it can’t be that bad,” he said while reaching out to pet Waddles. The pig caught a whiff of the bacon grease on Soos’ fingers and snapped at them, squealing and fighting violently while his suddenly-sharp teeth gnashed the air. The janitor yanked his hand back. “Oh wow, that is bad.”

Tears streamed down her face as she ran back up to the attic with Waddles. She slammed the door and then fell onto the bed with him, crying on him as he struggled to break free. Then all of a sudden she bolted upright and looked across the room. The edge of Dipper’s book 3 was sticking out from under the mattress. She swaddled Waddles, making him literally a pig in a blanket, then got the book.

Mabel dropped it onto her bed and started flipping through the pages at random, not really paying attention. “Maybe I don’t understand this stuff, but you know who does.” she said in sing-song. Waddles raised his nose at her curiously.

Mabel reached under her own mattress and pulled out an ornate gold pendant on a thick rope chain. The centerpiece was a disc about the width of a golf ball, with an indented edge except for two peaks that came out of either side of the top, like ears; two slits above the center made its eyes, and several curved sistrum crossbars radiated from the center to either side, like whiskers.

She quickly draped the chain over her head and let the pendant hang free before standing upright. She looked to the ceiling and tucked her fingers into her palms while batting at an imaginary string. A thick mist billowed up from the floor and enveloped her completely. Moments later it subsided, revealing Mabel now in what looked sort of like a tennis skirt with a high hemline. Above was a low-cut halter top that bared her shoulders and left her midriff bare under golden feather tassels. The pendant was now mounted on a golden collar. On her feet she had soft white linen boots that went halfway up her calves. Her hair band had become a lush purple with specks of gold, and her ears were adorned with cat-face studs.

Waddles watched attentively as she was fully revealed. Then with a confident smirk, she returned to the edge of the bed and leaned over the open book. The back of her skirt rose and readily exposed her lower butt cheeks. She called out in a booming voice, “When pig-eat-pig, fat and lean / Find the spell to make treif clean!”

A sudden powerful gust of wind blew the window open. Books flipped open in the breeze; stuffed animals rolled around in the chaos; papers, candy wrappers, and even loose socks left on the floor spiraled around. The book’s pages flapped wildly, yet Mabel’s skirt and hair were left perfectly undisturbed. After a few seconds one of the pages was plucked from the book and flew right into Mabel’s face. The wind died down as she pulled the page away and read it. The Forest of Forgiveness. She smiled. “Let’s go Waddles! We’ve got work to do.” She threw open her dresser and quickly pulled out a lavender sweater with three smiley-face flowers decorating the front. As she pulled it over her head her white skirt faded away and she was suddenly back in her jeans. After slipping on a pair of short socks and her sneakers she whisked up Waddles and was out the door.

Even though the midday sun was shining brightly over Gravity Falls it seemed like night in the thick, decaying woods as Mabel followed the directions on the page. It was difficult as she was trying to keep from tripping over the many roots and thorny vines that encroached on the path. Waddles followed closely and occasionally squealed in fear even though his stomach growled angrily. “This way boy.”

At last they came to what would have been a clearing, an open area with few roots, but huge dead-looking trees towered overhead and their gnarled branches interlocked so tightly that only a few spots of light shone through. There were three shafts of light, forming a large triangle in the middle of it all. One beam illuminated a small patch of plants with pointy lush green leaves while the other two landed on some small, strong looking trees. Mabel scooped up Waddles and carried him to the very center. She placed him on the ground, pulled out a compass, and made him face 325°. He tried to squirm away but several tendrils snaked out from underneath the dead leaves and pine needles, taking hold of his legs. Mabel seemed unperturbed as they pulled his legs inward so that they were held fast against his body as he was forced to rest on his belly.

She knelt down and looked at him apologetically. “I know, I know, but this will make you all better and not crave eating your relatives.” She snickered to herself, “Hypocrite.” As she leaned forward to kiss him her amulet fell out of her sweater. Waddles grabbed it in his mouth and pulled on it, trying to keep her close. She smiled and lifted the chain off her neck. “Here, if it makes you feel better you can play with it.” She tilted her head down and shook it vigorously until it came off, pulling her hair down over her face before it was snatched away by the pig.

Mabel petted him for a moment as he nosed and chewed on the chain, getting it all dirty. Mabel got up and went to the plants. With some effort she yanked up one of the spiky things, revealing it to be a pineapple. Then she went to one of the trees and plucked off a big apple. From the third tree’s flowers she plucked off some dried up black nubs. Then she brought them all over to Waddles and got down on her knees.

First she raised the pineapple and, while biting her tongue, carefully pondered it. “Oh!” she said while gripping the top and unscrewing it off the body. Mabel hooked several pineapple rings onto her fingers and then spread them all over Waddles’ back. “First we have the Pineapple of Penance.” Next she stabbed the little black nubs into the pineapple rings, making Waddles squeal like mad. “Oh sorry baby. Did I jab you with the Cloves of Contrition?” She petted him until he calmed down. “And finally,” she said while carefully spreading his jaw and inserting the apple. “The Apple of Apology!”

Waddles squealed and cried as the little bits of sunlight faded and the wind picked up. The vines pulled his body almost all the way into the ground. Mabel was saddened by his distress but she just rubbed his neck and face. “Don’t worry, it won’t be long now,” she explained while checking the page again. “Just three minutes per pound and you’ll be all done. I know you don’t like being tied up, but I’ll tell you a secret.” Blushing, she leaned in close and whispered in his ear, “Sometimes I wish Dipper would…”

*CLICK!*

Suddenly Mabel felt a metal collar lock around her neck. She shuddered. “Oooh, Dipper, is that you? Were you listening?” She instinctively grabbed at her neck and tried to pull it off, but it fit her perfectly and wouldn’t budge. Mabel got a dreamy smile as she cooed, “Dear Spazzgirl Letters…”

Then she turned, hopefully expectant, but her smile was replaced by disgust when she saw the brown shoes and baby blue pants. She instantly recoiled and shielded Waddles as a whiny voice cried out, “At last Mabel Pines, now you are totally in my power!” Standing over her was Gideon Gleeful, the preacher boy. Short and tubby, he had poofy white hair, a blue suit, black shirt and white tie.

Mabel shot him a curious look as she let go of her pig and yanked the leash out of Lil’ Gideon’s hand. “No I’m not, you weirdo.” She stood up and tried to take a step forward only to find that her feet were stuck to the ground. She struggled to pull free for a few seconds but couldn’t, and when she tried to hold the leash's handle it zapped her hand. “Okay, I guess I’m a little bit in your power.”

After stepping in close he snatched the leash away from her. “You are ensnared by The Loaner Leash. Uhm, not a great name I know. My father and mother brought it back from their special parents club once. My father said it was the only way he could get Mom to come home.” Then he cleared his throat as he got back on point. “Anyway, as you see, your feet are completely under my control. You can’t move in any way that I don’t want you to, my juicy little peach.”

Mabel slapped him hard on the face, making him yelp in pain. “You don’t talk about my juicy peach, you midget monster!”

Gideon took two big steps back while rubbing the stinging red mark and muttering, “I forgot it only controls your legs.” Then he snickered. “Oh, and that’s gonna be so helpful for what I have planned! Hahahahahaha!”

“Uhm, dinner and a musical?”

Gideon rolled his eyes. “No, I’m gonna make you mine for once and for all, and then I’m gonna rub your stupid brother’s nose in it.”

Mabel gasped and covered her mouth, but quickly she recovered. “No way! I’ll never do that with you, no matter what!”

“Oh really? Well, then why don’t you turn around and tell your pig that.”

With that Mabel’s legs started moving on their own, and no matter how hard she fought it she found herself facing Waddles. The pig whined nervously. Gideon walked around to face her from the side. “Now, take a good look at your defenseless little friend here.”

“You leave Waddles alone!”

“Oh, I wouldn’t hurt a hair on his chubby little head. Would you?”

“What do you mean? Of course not!”

“Really,” he said while showing off an evil grin. “Why don’t you raise one foot back then?” Mabel was helpless to stop her leg from going back and found herself balancing on one foot no matter how hard she struggled, even just to fall down. Her raised foot was aimed squarely at Waddles side. “Imagine how your little piggy would feel after you brought him out to the middle of the woods, tied him down, and started kicking him.”

“Noooooo!”

“Yes, Mabel, tell me. How many kicks before he would think you didn’t love him anymore? How many until he could never trust you again? Or even hate you and run away forever?”

Tears flowed down Mabel’s cheeks. “Okay okay! I give up. I’ll do whatever you want.” Waddles whimpered sympathetically.

“That’s more like it. Now, give me your phone.” Mabel tearfully complied. After shutting it off he dropped it in his suit pocket then tugged on the leash. “Let’s go. Oh, don’t worry about your little friend. He’ll be safe here.”

With her head hung low, Mabel didn’t even fight back as they started to walk. “Dipper’s gonna find me, you know.”

“I’m counting on it. But all he’s gonna find is your phone – after we record a very special movie for him to watch on it. And it’ll be too late because you’ll be mine forever!”

As they left, Mabel murmured and sniffled while Gideon went on about how sorry Dipper would be.

Wendy leaned back in her chair behind the counter, quietly talking on the phone while Dipper swept the floor. Occasionally he stole a glance at her but quickly turned away whenever she seemed to notice. After the tenth time Dipper had to suddenly turn away and start whistling as Wendy finished her call.

“So Dipper, are you spying on me?” she said with a teasing smile.

The boy turned white. “I, uhm, I don’t know what you mean.”

“C’mon, you keep looking over here. I get the feeling you’ve been spying on me all day.”

“No I didn’t! I mean, no, not at all, heh heh heh. I was just looking at the clock. Yeah, because I thought Mabel was going to be here by now so maybe we could take a break.”

“Now that you mention it, I was wondering why things didn’t seem as fun as usual here today. No offence! Anyway I hope she’s okay.”

Dipper looked at the clock for real, then out the window. “Hmm, Maybe I should go look for her. Do you mind?”

“Of course not, man, you really need to find her. Just leave the broom there and I’ll take care of it.”

“Ok, thanks,” he said. “I’ll be back soon.” Dipper grabbed the doorknob.

“If I’m not here you always know where to find me.”

Dipper stopped cold in his tracks and his eyes went wide. “Uh…”

“The roof.”

“Oh, yeah.” After some forced laughter Dipper pulled the door open to find Waddles there. He felt a shock as the muddy, wide-eyed pig squealed at Dipper as if in terrible pain. Dipper knelt down and petted him reassuringly while checking him. Not finding any physical injuries, he picked Waddles up and brought him inside. “What’s the matter, boy? Where’s Mabel? Is she okay?”

“Not to be a jerk or anything,” Wendy interrupted, “but you know Stan’s gonna freak if he finds Waddles inside all dirty like that.”

“You’re right.” Dipper headed to the stairs. “I’ll get him cleaned up then see if he can help me find Mabel. No way she’d ever leave him unless she couldn’t help it.”

Just after Dipper disappeared upstairs a haggard looking Grunkle Stan returned to the shop. When he saw the broom and dustpan out and Wendy behind the counter he asked, “Hey, where’s Dipper?”

As she pulled out a magazine she answered plainly, “He’s giving the pig a bath.”

“Now that’s a really weird way of putting it.”

In the chilly basement of an abandoned warehouse Gideon was standing on a small crate as he gleefully tightened the straps around Mabel’s wrists. He secured her arms straight out to her sides to the concrete wall, though her legs remained free. The old fluorescent tubes above his victim flickered as he removed the collar from her neck. Mabel’s sweater was gone, her skin was slightly red and she was covered in perspiration. “Thank goodness it’s over,” she moaned weakly. “I can’t believe you’d make me do that, you monster! It’s sick!”

Gideon stepped down and faced her. “C’mon now, my pretty little pumpkin, why walk all the way to my secret lair when you can Morris dance?” The chubby boy turned to the side and awkwardly shook his rump at Mabel, making her turn her face away in disgust. He turned to her and cupped her face in one hand. “But you’re always so full of energy that I know we’ll still be able to make our little movie. Oh boy, your brother will be so angry it’s likely to be downright adorable!” He laughed, then as an afterthought, ran his fingertips from Mabel’s chin down to the collar of her tee shirt. He suddenly pulled his hand back and turned away, sighing deeply.

Mabel looked at him suspiciously, raising her eyebrows. She smirked before catching herself. “You know, it’s bad enough you’re gonna rape me and stuff, but it’s a little annoying that you’ve got me right here, totally helpless, with no way to stop you, and all you can talk about is Dipper. Can you at least pretend I’m the irresistibly sexy reason you’re doing all this?”

“Of course you’re the reason!” he snapped. “But if it makes Dipper notice, I mean, if he has to acknowledge that I’ve defeated him… or you… both.” He turned around to drape his suit jacket next to Mabel’s sweater on a chair.

“You know what I think? I think you’re really more into Dipper than me.”

Gideon’s face turned dark red and he stuck his finger in Mabel’s face. “What do you mean!”

“Well, you are a preacher after all, and you know how that goes.”

“NO! I mean, no. What would make you think that? I’m not that way. Besides, haven’t I’ve been trying to court you all this time?”

“Yeah, I know, but we were more gal-pals than anything else. You didn’t start to freak out until Dipper told you to leave me alone. I think that’s what this is all about.”

“Nonsense!”

“Okay, never mind then. Why don’t you just come take my clothes off and do whatever you want to me?” Mabel moved her hips forward and rolled them at him.

Gideon turned and snapped at her. “Uhm, because I want to take my time and enjoy myself. And make you enjoy it too, of course.”

“You seem to be enjoying yourself just fine thinking about my brother.” Without thinking, Mabel spread her knees and began rhythmically rocking her hips back and forth, getting the jeans to just barely slide over her mound through her panties. “Oh yeah,” she gasped. “You’re probably imagining his pretty face, those deep blue eyes, his silky hair, those too-perfect lips… kissing them. Wow! No wonder it’s hard… to concentrate on me.” She closed her eyes and moaned, “Oh yeah, I wanna do you so bad.” Then she remembered where she was and her eyes shot open. Mabel looked at Gideon and licked her lips as she beheld the bulge in his pants. “If it’s me you want it looks like you’re ready. So come over here and take off my pants and do stuff to me.”

Gideon nervously walked up to her. “Well, I’ll call your bluff.” Very slowly, he reached out and unbuttoned her jeans. Then he carefully placed his thumb and index finger on the outside of the zipper. He sucked in a deep breath and let it out, right on Mabel’s midriff. She sighed and he cringed, then fiddled for a second or two before slowly pulling the zipper down. When he got about halfway there Mabel wrapped one ankle around the back of his.

“AIIGH!” He jumped back and tripped on her foot, causing him to land on his wide bottom. “What’d you do that for?” he whined.

Mabel began squirming in her loosened jeans, quickly getting them to mid-thigh and exposing her pink and blue satin panties. “What? I thought you were finally getting into it and I wanted to help things along.” She giggled. Gideon averted his eyes until he caught a whiff of her intimate scent, causing him to look up curiously to see if her panties were actually wet. With the poor lighting he couldn’t tell right away and had to stare.

After kicking off one pant leg she half-lidded her eyes and purred, “Don’t just look at it. I can’t get these panties off by myself.” She quickly reached over with her free foot and stroked the inside of his thigh, noting that his boner was gone. He pushed her foot away and scooted back before standing up again.

“Aww, am I not being sexy enough? Maybe this will help.” Then she continued in a deeper mock voice, “‘Oh gee, it says in my book that there’s a big mystery for us to solve, Gideon. The mystery of boy-boy love. Just stand behind me and hold onto my thighs while I lean over this table and see what’s on the other side. Maybe you should go in the back door. Heh heh heh!’”

“Stop it!” he spat.

“Oh give it up, Gideon. You are so in love with Dipper that you should just order the cake already.”

“No! I want you – YOU! And I’m gonna have you right now!” he insisted.

“How? Are you gonna turn me around to face the wall and pretend you’re playing with Dipper’s smooth, firm butt instead? Then breathe down his neck as you feel him from top to bottom with your shaky, sweaty hands.” Gideon breathed heavily as Mabel closed her eyes and continued, moaning, “Kissing the back of Dipper’s neck, smelling his hair, pressing your body up against his, making a dimple against his butt as you rub your face between his shoulder blades and smell him. Then you lick your fingertips, reach around and squeeze his little boy nipples while your other hand caresses up and down between his butt cheeks…”

Mabel snapped her legs together when she felt the wetness of her panties against her chubby labia. She nervously looked at Gideon to see if he noticed, but he was too busy trying to hide his raging boner without giving in by turning away.

Dipper patted the whimpering pig dry with one hand while contemplating the cat-themed amulet in the other. “What the heck are you?” Waddles rolled over and looked at him with sad eyes. Dipper pulled out his mysterious book and started flipping through it quickly. Near the end he found one page that seemed much thicker than the others, and he realized that a piece of regular paper had been glued to it. From the back he could see the faint shape of the amulet. He tried using his knife to separate the sheets but only scraped down half the dark alien symbols on the book’s page. “Well, if it’s to save Mabel,” he sighed as he started scraping away the paper to free up the other sheet. After destroying the original page he was able to look at the picture and read what was written in sparkling ink:

"Oh my queen!" said the royal sorcerer to The Younger Lady. "With this amulet you and your descendants are endowed by the goddess Bastet, with the powers of the kittens and of the little girls. Your silliness will charm all who are near, your curiosity will outshine your mortality, you will be able to ignore others so adorably that they will try only harder to please you, and you will command the elements of yarn and of shiny things."

Over three-thousand years later, a really super awesomely pretty girl tripped over this lost treasure and found that she liked how really really cute it looked on her. But if her bossy brother found out he'd take it and say it was part of the (and I'm quoting with my fingers here, Dipstick) "Big Mystery" and she'd never get to wear it again. So, unknown even to her two best friends, Candy Chiu and Grenda, uhm, I don't know her last name, she became a dual-person. Mabel Pines - and Kittycat Girl! Dedicated foe of the boring, defender of the silly, champion of all who can't figure out just how the heck a laser pointer works.

So if you find this, Dipper, I'm sorry I didn't tell you about it before. Because I mean why else would you actually rip up the Love Potion page I superglued this to? Seriously bro, if your searching this stupid book that hard then something REALLY BAD must've happened.

XXX OOO QQQ,

Mabel

(and Waddles too in case he's in danger with me)

P.S. All that junk up top was carved on the box the amulet was in. It looked like it was written in hiroglifics too and also in some of those symbols in the book that you can't figure out. But the box had a metal bug on top LIKE YUCK! so I had Soos burn it.

P.P.S. What are you waiting for, stupid! SAVE ME!!!! AGGGGHHHHhhhh!!!!!!!!!!!!!

Dipper looked at the amulet. “Well, that kind of explains what it is, but what would have helped even more is if she wrote down how to use it.” He put it on, straightened it out, and turned to Waddles. “Any chance she showed you?”

The pig, still on his back, raised his forelegs and shook them while mewling a few times.

“Guess not. So let’s try,” Dipper started pushing the front like it was a button, but nothing happened. Dipper was undeterred. He stood up straight with his chest out, “’Oh Mighty Bast!’” Nothing happened. He tried flicking the “whiskers” on the amulet, wondering if there was some musical code, but after a rendition of “Twinkle Twinkle Little Star” with an Egyptian flair, still nothing. Dipper grew frustrated. “Hmm, how would Mabel’ve reacted to finding this?” His eyes lit up and he started petting the amulet while saying, “Oh, who’s a good goddess of cats? You are! Yes you are! Such a pretty cat goddess, meow meow…”

Mist billowed from unseen places and filled the room for several seconds, then revealed Dipper waving away the last puffs of it. Now he was dressed in a tiny white linen open jacket with the same velvet and gold trim. It barely fell below his nipples, so half his chest and all of his stomach were completely exposed; the amulet was now hanging right between his nips on a gold metal ring around his neck. His bottom half was mostly uncovered with white shorts that matched the theme but were a size too small, though they were a bit stretchy as to be more comfortable. The outline of his package showed an uncomfortable amount of detail. The shorts stretched over the lowest point on his back, risking some butt cleavage. On his feet were sandals that strapped up to his calves.

Instinctively Dipper called out, “Oh goddess of scent, help me find my sister! …um, because I’ve really super-duper missed her.” The amulet lit up and projected a tilted image of Gideon walking Mabel by the leash into an old abandoned warehouse in the abandoned warehouse district. The view zoomed out and the hieroglyphics for “Calculating Route” appeared for a few seconds then turned into a map from The Mystery Shack to the warehouse.

“Okay Waddles, you stay here where it’s safe.” Dipper bounded for the door, hopping and landing silently and then he quickly tiptoed down the stairs. He stopped at the front desk, staring at Wendy like a cat for an instant to catch her attention. She put down the magazine and looked, only for her eyes to light up and her jaw to drop as she gasped. “Looking mighty good, Dipper!” she said while slowly clamping her thighs together.

Dipper blurted out, “Gideon has Mabel! I’ll be back soon as I can, so cover for me.” With that he leapt, landing on his hands and bouncing up onto his feet again as he opened the door and ran into the woods.

“STAN!” Wendy cried out.

“What?” he answered from the office.

“I need to take a break.”

“On a day like today your whole job is practically one long break!”

“Women's troubles,” she called back, not at all convincingly.

Stan immediately appeared. “WHOA! Too much information. Go lie down or whatever.”

Soon as she was past him she smiled and hurried up the stairs while mumbling, “Time for me to wash the pig.”

A loud, low metallic ringing reverberated throughout the basement, stealing Gideon’s attention from their argument. “What in the blazes could that be?”

Mabel just looked down the dimly lit corridor and then smiled at Gideon. “Cake’s here.”

“Stop it!” he snapped. A few seconds later they heard the door slam, which made Gideon’s face flare with anger. “How the heck?” He was cut short when he saw a shadowy form slowly approaching in the darkness. A chill ran through his body when he saw the figure slinking towards him, with two giant glowing eyes piercing his very being. “Get away from me you demon!” He shot his hands forth at the approaching form while backing away towards Mabel. “The power of Gideon Gleeful compels you!”

“Pfft! Some big brave stud you are. Now you know why I’m not in love with you. Oh, yeah, and because you don’t like girls.”

“Cut that out!” he yelled at her but then turned back to the intruder. The shadowy form stepped into the light and the white-haired boy’s pants tented. “D-D-Dipper?”

Still in his tight costume, Dipper stood tall with one hand on his hip and pointing the other at Gideon. “You let Mabel go or…”

Mabel interrupted with a loud catcall. “WOO HOO! Yeah baby, that’s what I’m talking about! ROWWR! Here kitty kitty!”

“Mabel!” his voice strained as he shot her a stern look.

“Sorry. Didn’t mean to interrupt you rescuing me and stuff. Oh, but that’s what Gideon’s thinking because he admitted he’s totally gay for you.”

Gideon turned to her and screamed, “I did not admit it!”

“Ha!”

Dipper noticed Mabel’s jeans around her ankles. His eyes narrowed at Gideon and he raised his hands with fingers tensed up like claws. “Hey! Why’s Mabel in her underwear, creep!” he hissed.

Gideon snickered. “Well, I was gonna leave you a video, but now you can watch live as I make love to your sister.” He pulled the leash out of his pocket. “I just gotta tie up the naughty kitty so I can watch him and make sure he won’t get in the way.”

Mabel rolled her eyes and muttered, “Dude, give it up. You’re not fooling anybody.”

Gideon whipped the collar at Dipper and it stretched out to him, but Dipper leapt out of the way just before it reached his neck. He jumped again, landing behind Gideon. The short boy spun around and whipped again but by the time it reached Dipper’s position he’d jumped up to the ceiling and was quietly crawling towards Mabel on the narrow electrical conduits.

Gideon turned this way then that, trying to see where Dipper had gone. “Come out, Dipper. You can’t win this. I will have your sister, and no matter how you’re dressed it won’t stop me.” He slapped his forehead and interrupted Mabel as she was about to comment. “I didn’t mean it like that!”

Mabel burst out laughing.

“Laugh all you want,” Gideon yelled while searching for Dipper. “At least I’m not a big pussy.” Then he spun around towards Mabel and whipped the collar up at the pipes. Dipper easily dodged it and it got tangled.

Dipper stared at him. “Why are you calling me a puss… Oh yeah.”

“And I just caught me a kitty cat!” Gideon cackled as he jerked the leash and the conduits broke. Dipper fell backwards and saw the leash coming straight for him, but without thinking he twisted his back so that he avoided it while righting himself. The collar snapped back in Gideon’s face, making him grab his forehead and yell, “Ouchie ouchie!” while running in small circles.

Dipper quietly landed next to Mabel. He was right up against her as he started unbuckling the thick straps.

“There’s no time, Dipper! Make me Kittycat Girl and you can fight Gideon while I get free.”

Dipper stopped and looked at her, with their faces so close that he hesitated. “Okay, but how?”

She bit her lip as her face turned bright red. “Kiss me.”

“Okay, if you’re sure,” he said. “Mabel’s eyes went wide but then fell in disappointment when he kissed her innocently on the cheek.

She let out a groan. “Not like that. It has to be, uh, special.”

Now Dipper began to blush too as he looked deep into her eyes and inhaled her scent. “Special how?” he said as his lips moved towards hers. Then he stopped and shook his head rapidly. “Wait, you mean, uhm?”

“Yes, you have to kiss me the way you want to kiss Wendy,” she explained, making her brother’s face turn bright pink.

Gideon’s whiny voice shot up from behind Dipper as he raised the collar. “At last I have you, Dipper Pines!” Dipper raised his arm straight out and slapped his palm against Gideon’s forehead, leaving the little boy looking down while running in place against Dipper’s hand.

Dipper felt his whole body pulse with each powerful beat of his heart. His breathing was deep and slow. “So, my first real kiss is gonna be with my sister?”

Mabel stared deep into his eyes. Her lips were half pursed and she unwittingly barraged him with short hot breaths. And they smelled like candy. With Gideon still struggling to reach up, Dipper pressed his mouth into Mabel’s and started off with a warm, slippery kiss. She was quick to open her lips just enough to let him know he was welcome. Still he hesitated until he felt Gideon clawing at his arm, so he gingerly slid his tongue out and, unsure of himself, licked Mabel’s teeth. She answered by sucking his tongue in deeper, alternately swirling it around and then half-pushing it back in hopes he would take the hint. He did. He slid his free hand onto Mabel’s waist and then onto her exposed lower belly as they traded tongue lashings. Finally he was able to tempt her tongue into his mouth and…

The mist billowed up and revealed Mabel in her Bastet outfit too. After backing out of the kiss, leaving Dipper gasping, she easily broke her arms free. Dipper leaned back to look and his eyes went wide for a few seconds as he beheld his sister’s awesome and rather under-dressed beauty. Finally the sound of Gideon’s cursing and struggling snapped him back to the situation. “We’d better come up with a plan complicated enough to stop Gideon for once and for all, then figure out the rhyme to make it happen.”

“Nah, I got this,” she said dreamily and Dipper let go of the evil boy, making him slip and fall on his face. Mabel knelt down and yanked the leash from his unsuspecting hands then snapped the collar around his neck. Before he noticed what she was doing she’d already grabbed the handle. “Sit boy, sit!” she commanded, “Right back there. Legs spread as wide as you can get them.” He had no choice to obey and sit down behind Dipper, just a little to the side and well out of arm’s reach. She dropped the leash and gave him a bare-toothed smile. “Don’t pout Lil’ Gideon. Just enjoy the show.”

“What are you talking about? WHOA!” Dipper yelped when Mabel grabbed his buttocks with both hands, squeezing hard.

She moaned loudly, “So firm.”

“But Mabel…”

“C’mon, you feel it too, right?”

“Yeah, sorry!” he said while trying to pull his butt away so he’d stop poking her with his erection.

She giggled. “Yeah, that, but I mean it’s like we’re supposed to, you know, be together.”

“I have to admit that the amulet let me track you by scent, and it was really really nice. But I don’t think we should…”

Mabel put a finger over his lips. “But we can make Gideon watch what he’s never, ever,” her volume increased, “ever in a million years is going to get!” The wicked little boy grunted angrily.

Dipper suddenly nipped her finger and when she intuitively pulled it away he kissed her hard again, not waiting before pressing his tongue back into her mouth. Mabel returned her hands to Dipper’s ass then, after stealing a peek at the horrid little preacher, she pushed down the back of his shorts, revealing two perfectly tight little buns. She gripped them, letting her finger sink into them as much as his firm flesh would allow. Between that and the kiss the two children forgot about their sibling status and their audience.

As their kissing became more furious Dipper slid his fingertips into the waist of her skirt, but then he reconsidered and brought his hand up her belly and tried to get it under her white top. The material instead slid right up and off her soft young breasts. He put his palm over one and carefully kneaded it. Touching a girl’s breast for the first time, for real, was too distracting and he lost his rhythm on the kiss. Leaving his shorts pulled half down, Mabel gently held his head and turned it so she could kiss his face and neck. He was too delicious so she started sucking as she worked back and forth.

After they played like that for a minute Dipper gently took her face in his hands and eased her back. He moved into kiss her again but faked her out by kissing her cheek before pressing her back into the wall. He bent down, sticking out his bum as if to emphasize it. He pressed on her shoulders as he began rubbing the sides of his face against her breasts, kissing them wetly in passing. Her nipples stiffened.

She held his shoulder and gingerly petted his head with her other hand. He took as much as he could of one of her little mounds into his mouth and began lashing and sucking and savoring it with the same force Mabel had applied to his neck and shoulders. Mabel squirmed and kicked off one boot, hitting Gideon’s inner thigh. Then she hooked that foot around the inside of Dipper's bent knee and raised her foot to massage one of his butt cheeks.

After a minute he drew back and the two smiled nervously at each other, but Mabel broke the tension by pulling him in for a short kiss. “Okay, I’m ready. Like really ready, so let’s make our own movie.”

Dipper suddenly looked nervous. “You don’t really want to record it, do you?”

“Uhm, maybe not, but let’s think of this as just a rehearsal.”

“You got it.” Dipper smiled and reached his hand under her skirt, cupping the bottom of her ass cheek. Then he called out in his summoning voice, “Gods of linen, don’t let it hide. / Make her panties move aside!”

“Silly!” she giggled as she squirmed her ass in his hands. “My outfit doesn’t even have panties!” She knelt in front of him as she pulled his shorts all the way down, letting the not-so-little Dipper spring into view. She put her hand around it and gave a few strokes, getting a feel for its warmth and hardness. The feeling in her hand made her pussy tingle and she stood up again, pressing Dipper back. “Okay, let’s get this someplace safe. After he stepped out of his shorts and she'd dropped her skirt she turned him in a small circle before making him face the wall again. He didn’t understand that she was giving Gideon an eyeful before returning to the starting position.

Mabel put Dipper’s hand on her shoulder as she turned to face the wall, exposing her soft little ass to him. He cupped a cheek with his free hand and gave it a squeeze as she leaned against the wall with her arms crossed in front of her face. When she spread her legs and stuck her butt out he didn’t hesitate. He held his cock as he moved it down between her thighs, and Mabel momentarily used one hand to line him up to her entrance, first rubbing its head back and forth to cover it in her dripping spume. Then carefully, Dipper pushed the head inside of his sister’s vagina, slowly pressing his hips then pulling back in a rhythm that had both Mabel and Gideon hypnotized. Soon he let go and began using just his hips to gently ride into Mabel’s happy tunnel over and over again, getting a little deeper with each stroke. Meanwhile he played with her breasts and occasionally kissed the back of her head and neck.

Finally his loins met her with little slapping sounds and he continued pumping into her. Mabel rested the side of her head against the wall and pushed her palms in beside her, using the leverage to help push back against her brother’s strokes. He held her hips for extra support too. She spread her left thigh out and wrapped her ankle around his leg, gasping as he started to drill her a little deeper. Dipper spread his legs, unintentionally giving Gideon a full-on view of his tight sack bouncing while his cock repeatedly disappeared into his sister’s nether regions.

Dipper slowed down and leaned against her, driving as deeply as he could then rolling his hips to work around her insides. She moaned loudly. He brushed her perspiration soaked hair out of her flush face and kissed her hard on the lips. She kissed him back between gasps of ecstasy. As he continued, he wrapped one arm around her waist and held her raised leg out with the other. He began pumping more quickly in shorter, deeper strokes. Mabel started grunting her approval with each thrust forward and Dipper’s breathing became hard and ragged.

“Now Dipper! Do it now!” she begged and moaned. He let go of her leg, which she kept raised even though it twitched wildly, and he gripped her tightly around the waist and chest as he screwed her with all his might.

His eyes scrunched up and he arched his back as much as he could without letting go. “I love you, Mabel!” he cried out as he drove himself into her full-force and his release exploded inside her. His dick felt like it was made of iron and his balls ached as he spurted several loads of seed into his sister. Upon feeling the first hot splash, Mabel’s insides clamped tightly around his member and then flexed, egging on his orgasm as her own shook her entire young body. A fresh wave of her juices leaked out, coating his tight sack as his spurting subsided. Mabel’s whole body suddenly felt warm and relaxed despite the cool damp air, and everything went bright white in her mind. Dipper held on, trying not to slide his extremely sensitive cock any more than just enough to milk out every last aftershock, each of which caused Mabel’s pussy to respond with a jolt of its own.

Finally Mabel started to come down off her high, only to revel in the feeling of Dipper holding her tightly. He rested his head against her back and caught his breath. After a few slow pumps to make sure they were done he pulled out completely. Dipper immediately turned her around and grabbed her face while kissing her feverishly. She held him tightly and returned the kisses, albeit weakly as she was still recovering from her haze. “I love you too, Dipper,” she moaned into his sweaty face as she rubbed her body up and down between him and the wall, writhing just like a female cat after sex.

They took turns laying kisses on each other’s faces and then Dipper stood up before fixing her top. When he knelt down to put on his shorts he stopped and gave the top of her slit a quick kiss, making Mabel gasp. Then he handed her her skirt before pulling his shorts back up.

After making googly eyes at each other they heard a small whimper from their audience, and they turned to see him fidgeting uncomfortably as he cupped his hands over the tiny wet spot between his legs. Mabel pointed at him and forced herself to laugh.

Dipper was more concerned. “Oh yeah, what are we going to do about him?”

Then they both looked at each other and smiled before turning back to him. Together they said, “No matter how what we did makes you grunt and scream / Whenever you remember you’ll think it’s just a dream.”

Gideon’s face went blank and his eyes closed as he slowly fell completely to the floor, unconscious. Mabel recovered her phone then pressed the release button on the leash’s handle. She rolled up the line and stuffed the whole thing into the waistband of her skirt.

Dipper took her by the hand. “We should hurry up and get back. I know someone who’s going to be very happy to kiss you up and down all over.”

Mabel’s eyes lit up. “Oh, Waddles made it back okay?”

“Him too,” Dipper quipped before licking up the side of her face, making her giggle. Then, after she picked up and put on her sweater, they walked down the corridor hand-in-hand. Their Egyptian outfits faded away and they were dressed normally again, though the transformation didn’t fix their hair or skin tone.

“What’s the deal with that leash anyway?”

“Oh, I'll show you,” she said while pulling it out again.

Dipper held the leash’s handle, with the line going up under Mabel’s sweater, as they talked quietly and entered the Mystery Shack. They found Wendy, Stan and Soos all there staring at them. “Oops!” Dipper quickly dropped the handle.

Wendy smirked at them and asked, “So did you two do it?”

“What!” they both gasped.

“Defeat Gideon, of course,” Wendy giggled.

“No, seriously,” Stan interrupted, “It looks like you two did it. I mean, seriously, look at those massive hickies Mabel gave you.”

“I know, finally!” Soos said.

The twins cried out together, “What makes you think it was…”

“…Me?”

“…Mabel?”

“You two are lousy liars.” Grunkle Stan then rubbed his chin while thinking. “I guess we’re gonna have to work on that now that you two are gonna be going at it like crazed weasels all the time.”

“Uh-nuh! It was just the necklace!” Mabel protested as she pulled down the top of her turtleneck, revealing the collar. Dipper slapped his forehead. Her eyes bulged for a moment and she covered up. Then she quickly reached around Dipper’s neck and pulled out the amulet of Bastet.

Stan continued, “Yeah yeah yeah. Like you haven’t been dying to jump Dipper any chance you got already.”

Dipper’s jaw dropped and he looked at Mabel. “Wait, what?” She turned sideways and kicked at the floor while looking down. Still, she couldn’t stop herself from smiling as she blushed.

Wendy jumped in. “You’re the one we were worried about Dipper. I thought Tambry and I were gonna have to get you drunk to make you tap your sister.”

“Wait wait wait!” Dipper stammered. “What’s going on here?! You’re not mad?”

“Okay, here’s the deal. Our family is descended from a long line of royal Egyptians – seriously, did you ever notice my hat? – who are really into that sort of thing, just like most royalty. Now, we escaped to America and kept low-key for all these generations while waiting for the prophecy of The Awes, er, Awful Twins to come true.” Stan took a breath. “That’s you two, in case I need to spell it out any more.”

“So wait,” Mabel asked, “We were supposed to make love?”

“And have babies. Lots and lots of babies. They’ll be so freakin’ adorable that they’ll have lots of babies too. Then our family line will expand like crazy and we can take control of the world. But I mean, sheesh, we waited thousands of years and then you two had to take your sweet time.”

“So our parents want me to get Mabel pregnant?” Dipper sheepishly asked.

“C’mon! Why else do you think your parents sent you two to spend the summer in the middle of nowhere, without anything to do or even cable TV? To make you better people? HA!”

Wendy added, “Besides Dip, did you really think Mabel is always so goofy on her own? It’s being around you that makes her a little silly.”

Grunkle Stan looked dismissive for a moment. “A little silly? More like full-on bonkers, and all for you, kid.” He put his hand to the side of his mouth and pointed at Wendy with the other while loudly whispering, “And I don’t think she’s the only one.”

Dipper’s eyes lit up. “Really?”

“A-HEM!” Mabel said while poking him in the ribs. “I’m first.”

“Hey! Grunkle Stan said we’re just supposed to have sex, not act like we’re married.” Wendy and Mabel fought back laughs while Soos and Stan guffawed. Then Dipper took Mabel’s hand in his and squeezed it. “I mean, always.”

“Oh, you’ve got it nailed, kid,” Stan said. “Now you two go get washed up for dinner. I’m gonna make a lot because I have a feeling you’re really gonna need your strength tonight.”

Soos added, “And I’ll go make sure your headboards are on tight and everything is properly lubricated. I learned how important proper lubrication is one time when my girlfriend…”

“Too much information!” everyone else yelled out together.

“Okay, okay,” Soos chuckled as he headed for the stairs.

Wendy put on her jacket. “Okay, time for me to go I guess.” As she stepped out she turned back to say, “See you tomorrow.” Then she put a finger under Dipper’s chin. “…morning. And wear the outfit. Tambry’s gonna freak!”

Mabel gripped Dipper’s arm. “He might be too tired.”

Wendy smiled. “Oh, I think I can get him up.”

Mabel snickered. “Well I know I can get him up.”

“Ow!” Wendy laughed. “Touché.”

“C’mon Mabel,” Dipper said nervously while leading Mabel to the stairs. “You can shower first.”

“First? Silly Dipper, you don’t need to wait. I mean no one said we have to wait until after dinner.”
