Dipper was torn. The idea of a threesome was gross, terrifying, but somehow… also exciting. He would see Wendy naked! But he would have to see Robbie naked. But would see Wendy’s butt freed from those tight jeans! But then he would have to Robbie’s dick. But he would Wendy’s boob’s! But he would have to watch Wendy have sex with Robbie. But he would get to have sex with Wendy! But he would have to have sex with Robbie. Dipper’s mind went back and forth like this for a while. His stupor was broke when Mabel walked in the door. Dipper’s eyes narrowed, angry and jealousy filled his head. How the hell could Mabel go behind his back like that. She knew he liked Wendy. Besides they were way too young to be thinking of stuff like that. There was also the fact that Wendy went to her… Should he call Mabel out?
            Dipper opened his mouth, “So, how was Greg?”
            Mabel nearly jumped out of Dipper’s skin. “Uh, fine. Great.”
            “So, am I going to have to go on a date with him?”
              “You know, I didn’t think that’s going work out like that.”
            Dipper sighed, “Oh thank God.”
            “But I am staying over at his hotel room tonight.”
            “But you just gave up on him. You’re not going to try to creep on him.”
            You have no idea bro Mabel thought to herself. Out loud she said, “I just think he’s a cool guy Dipper.”
            Dipper was too tired and angry to think too deeply about this. “Whatever, I just don’t to see videos of myself painting toenails or something online okay?”
            “No problem Dip. I’m gonna let Grunkle Stan know.” She ran off to her Grunkle.
            “Sure, thing Dipper,” Stan said. “I’m glad that you’re finally making some friends your own age. It’s good that you get along Soos and Wendy but being with your peers will be good for you. Besides your sister is having a sleepover with her own friends tonight so this works perfectly.”
            How could she be so stupid! Mabel totally forgot about Grenda and Candy coming over tonight! Stupid, stupid Mabel. She ran over to Dipper to explain the sleepover to him. Dipper was less than pleased.
            “Great, not only will you be doing God knows what with what’s his face, now I have to entertain your friends.”
            “What’s with you today? You’ve been a huge butt.”
            “I don’t know but it seems like I always lose everything because of you!”
            Mabel felt tears come to her eyes. She was shocked by the level at anger she felt from her brother. “What are you talking about? Is this because I switched bodies? Because I didn’t know…”
            Grunkle Stan came running into the room. “I heard shouting. Is everything okay?”
            Dipper and Mabel glared at each other. Despite the tension, both thought it was strange to be staring down their own faces. Mabel found her voice. “Everything is fine Grunkle Stan.” She grabbed her bag. “I was just leaving.” And she stormed out the room.
Later Dipper changed into Mabel’s sleeping shirt. He still felt a twinge of embarrassment changing clothes in his sister’s body. But it was getting strangely easier. At least he knew how to pee. Grenda greeted Dipper with a crushing hug. “Are you ready for a fun night Mabel?”
            Candy dumped the content of her bag. Board games, trashy romance novels, and teen zines spilled out onto the floor. “Totally ready…gals.” Dipper’s fake grin was hurting his face.
            It must have shown on his face. “Are you okay Mabel?” Candy asked.
            “What? Yeah. Yeah. I’m just peachy. You know me, Peachy Mabel.”
            “Come on Mabel. Just tell us.” Candy grabbed Dipper’s hand. “Whatever it is, we want to help.”
            Grenda grabbed both Dipper and Candy in a head lock. “Yeah! That’s what friends are for!”
            Dipper was thrown off. He was not used to this much positive reinforcement. It was a bit disarming. Grenda loosen her grip and Dipper slipped his head out and he made his way to his own bed and sat on his own bed.
            Candy and Grenda looked at each. “Uh Mabel? Why are you sitting on your brother’s bed?”
            “It’s been a hell of a day.” Dipper ignored the girls squeaks at their friend swearing. “And I’m a little stress after Wendy asked me in be a threesome with her…” Grenda and Candy’s mouths dropped. “I shouldn’t have said that out loud…”
            Meanwhile Mabel was sitting on the hotel bed. Greg’s parents seemed nice if a bit distracted. They barely seemed to notice her. They were gone twenty minutes after Mabel showed up. For dinner, the duo ordered several pizzas and ice cream. They watched Labyrinth, cuddling close together. Half way through the movie, Greg sat of Mabel’s lap. They began to kiss each other deeply. Soon they were tearing off each other’s clothes.
            “Hold on,” Greg went to get something. He came back with a large jar. “This is lube.” Greg pulled out a glob of what looked like jelly. “I got it online. Got it fast delivered.” Mabel watched, fascinated, as Greg smeared the Jelly around his cock. Mabel felt her own twinge. Somewhere, deep in her brain she thought that it was her brother’s penis that was twinging, but it was buried underneath to much desire for her to care. Greg used his index finger to pull a glob of lube. He held his finger close to her butthole. “Dipper, do you want this?”
            Mabel nodded, “Greg please, I need it.”
            Meanwhile, Candy and Grenda was still processing what Dipper had just said. “And you said yes!”
            “I didn’t know what else to say Candy! It took a while for what she was saying to sink in!”
            “Why don’t you just call her and tell her no!”
            Grenda stood up and shouted, “No, Mabel you can’t miss out on an opportunity like this!”
            Dipper was surprised by this. “I, uh, what?”
            “Mabel listen to me. This is a once in a lifetime chance. How often are any of us gonna get a chance to be treated like an equal, like an adult with high school kids?”
            “Yeah, YEAH!”
            “Besides, you gonna get a chance with a cutie like Robbie.”
            An image of Wendy in her red swimsuit flashed in Dipper’s mind. “Yeah, Robbie.” What was it with girls and terrible taste? “But what is if I mess up? I don’t have any idea how you know… sex works. Like I have a general idea but… what if I embarrass myself with Wendy?” And then he hastily added “and Robbie.”
            “Well, Wendy shouldn’t that hard. Wouldn’t it be like you know, masturbating?” Candy whispered the last word as if someone might be listening.
            “How do girls… you know?”
            “Mabel, have you never touch yourself down there?”
            The truth was he was masturbating regularly for about six months now. But that was a different set of equipment than what he had now. “No.”
            Grenda stood up. “Well there’s only one thing to do! We’re going teach you about sex and stuff!”
           “We are?”
            “Yes Candy, we are. What are best friends forever for? Are all those friendship branchlets we made are lies?”
            Dipper’s face became beet red. No, this is wrong. Abort, abort. But what Dipper heard come out of his mouth was, “Okay.”
            Meanwhile, Mabel and Greg where taking things to the next level. They were on the bed. Mabel was flat on her stomach, she could feel her member pressed against her stomach. Greg was behind her on his knees. He was gently prodding Mabel’s butt, rubbing the lube around her anus. Mabel was naked expect for Dipper’s hat. Greg was completely nude. Mabel was breathing heavily. “Greg please, I’m going crazy here.” Greg didn’t say anything but responded by sticking his finger in her butthole. Mabel bit into the pillow. This felt great but it wasn’t enough. “Greg, stop teasing me.”
            “I’m not teasing you Dip. I’m just applying the lube so it doesn’t hurt. I read online that you need pliantly of lube.” Greg finally removed the finger. Greg slapped her sides signaling her to get on her hands and knees. She complied. Mabel felt something bigger than a finger press against her entrance. “Are you ready?”
            “Yes.” Greg pushed his penis into her. “Yeeeeeah! Holy fudge, Greg.” Greg felt the warmth embrace his member for a second. Than he began to slowly pump away. She heard the sound of his body slap into hers with little thud, thud, thud. She felt her own member bop around. “Hmmm, fudge, fudge, fudge. Ah, I love you, I love you, I love you.” Greg began thrusting faster and each thrust Mabel muttered an I love you. She soon felt a tingle in her head. The same tingle she felt in the shower and back in the woods. She screamed as she climaxed, getting semen all over the bed sheets. Greg was cuming as well. He blasted his load deep inside Mabel. When he was done, he dislodged himself from Mabel’s butt. Greg sat down, Mabel laid on her stomach. Mabel looked back at Greg, a devilish grin on her face. “I say we switch things up for round two.”
            Back at the other sleepover, Grenda had sat up on Dipper’s bed hiking up her night shirt. She pulled her underwear to the floor and stepped out of them. Somewhere inside Dipper’s brain he was thinking, “This is wrong. I shouldn’t be doing this in this body, it isn’t mine. Also, they have no idea that I’m a boy let alone Dipper.” But an overpowering emotion was preventing himself from stopping this, horniness.
            Grenda spread her legs revealing her vagina. Candy piped up, “Grenda we might need some towels.”
            “Right, thank you Candy. You’re so smart!” Grenda clapped Candy in the back as she set up the towels. Grenda sat on one while the other was put at her feet. “It can get kind of messy.” Candy gave one to Dipper to sit on, while she sat on herself.
            Looking at Grenda rubbing her thighs, Dipper could help but look at her pussy. “Well, it looks like Grunkle Stan owes me twenty dollars,” remembering a bet with Grunkle Stan after they had met Grenda.
            “Okay Mabel, the best thing to do is to warm yourself up by rubbing your thighs.”
            “This seems a little advanced for us since were just you know twelve.”
            “Grenda looks up this stuff online all the time.”
            “Candy! Oh my gosh. Before you go at the clitoris...”
            Dipper interrupted, “The what?”
            “Wha? The little button thing on top of your vagina. Come on Mabel!”
            “Right, right, right. As someone who has always been a girl I total knew what that was.”
“So, anyway you use your fingers to massage the sides.” Dipper could feel his own pussy start to get wet. He really hoped this didn’t stain Mabel’s underwear. Maybe he should remove them to be sure. Candy’s face was also starting to get red. Dipper quietly slipped out of his underwear.
“Th-than you, ah, switch to the clit.” She pulled her finger from her wet pussy. Grenda than used two fingers up and down on her clit clitoris. Her grunts and moaning got even loader.
“I hope Grunkle Stan doesn’t her this,” Dipper thought to himself. Grunkle Stan, meanwhile was in the basement, the secret one behind the vending machine. Seventies rock was blasting while he was welding some strange metal. He wasn’t hearing anything that was going on in the attic.
“Hey, Grenda, I th-think that it-t’s time for Mabel to have some hands-on practice?” Dipper turned his head to see Candy’s bare pussy. Dipper could feel his own juices dripping from crotch. He edged closer to his sister’s friend. “Mabel, please…” Dipper stuck his finger into her wet mound. He did his best to mimic the movements that Grenda made. Judging by the screams she was making; his best was pretty good. While he was working Candy, Dipper’s left went down to his own pussy.
“Oh, fuck.” The sensitivity of his walls surprised him. Dipper began to work Candy’s clit, while Grenda finished herself off. She then came behind Dipper reached her hand around and began working on Dipper’s clit. “Faster, faster, oh God Grenda faster.”
While this was going on, Dipper was going faster on Candy. “Uh, Mabel, please don’t stop! Don’t stop!” Candy soon found herself coming. Dipper find himself coming as well. The girls found themselves flushed, panting, cover in sweat and other bodily fluids.
After a moment Grenda spoke. “Uh girls? I think we might have over done it.”
Back at the hotel, Greg was flat on his back as Mabel entered him. Mabel started thrusting deep into Greg. The look on Greg’s face was so cute. She could she his thing laying against his stomach. She had a desire to get close to him. Mabel pulled Greg up on to her lap. She held on to him. She could feel his member pressing against her stomach. “Oh Greg, I love you!”
“Dipper, I’m…” Mabel felt Greg give another orgasm as his hot speed spill on her stomach. She soon felt herself cumming deep into Greg’s bowels. She kissed her love hard, rolling each other’s tongue’s together. Mabel couldn’t believe that her body still had that much her. Tired and drained she dislodged herself from Greg. He had already begun to drift off to sleep. Mabel cuddled up beside him, both naked as the day they were born and covered in each other’s cum, and slowly doze off.
