‘Santa’s Little Humper.’
Lisa’s heart sank when she checked her phone. She hadn’t been able to face anyone since she read Bart’s latest text message. There was no context, no explanation, and no reason for her brother’s correspondence. Her phone buzzed with the notification just before school, and Bart never elaborated on what he had sent his sister. But Lisa knew exactly what he meant.
Bart had caught her.
Lisa had been fucking the family dog for weeks. Every so often, when she was sure she was alone; Lisa would invite Santa’s Little Helper up to her room and bend over for him. She had become his mate, his bitch. And she loved it. Over the past couple of months, Lisa had trained her body to take his cock and his knot. Santa’s Little Helper had sprayed countless loads of canine cum deep inside her willing pussy. His paws around her waist, his chest atop her back, Lisa couldn’t get enough of it. But Lisa grew more daring the more time she spent with her pet. She found that she could no longer wait until her family was out. Lisa had resorted to slipping away from school during lunch in the hopes of a quick fuck. Sometimes she’d return to class with a load of dog cum swimming inside her, sometimes she wouldn’t. It always depended if her mother was home. Sex with Santa’s Little Helper was becoming an addiction and Lisa was pushing the boundaries of caution so she could get her fix. She would invite him into her bedroom at night, take him for walks in secluded areas, and even purposely get him dirty so they could share the bathroom. Lisa knew she had to steady herself and fight the urge to be mounted.
‘One more time,’ she thought to herself as she quickly excused herself from dinner. ‘And then I cut back tomorrow.’
Lisa sat on her bed. She had just walked home from school. Her bare feet dangled against her covers and she held her phone in her hands. She was hunched over; worried, scared… she didn’t know what would happen. How long had Bart known? What proof did he have? Her response to him earlier in the day remained unanswered. Lisa knew she couldn’t blame him, of course. If she had such leverage over her brother then she’d be holding it over him for all it was worth. Lisa heard the soft thump of the front door closing on the landing below her. She listened to the sound of calm footsteps ascending the stairs to the second floor. Lisa’s eyes followed along the wall in her room as Bart turned into the hallway. Her gaze slowly panned across her room and passed her door, catching the small shadow of Bart walking right by her bedroom. Lisa sighed when she heard his bedroom door close.
He hadn’t spoken to her all day.
Lisa didn’t know what she was expecting. Was he just teasing her? Playing her? Leading her along? She didn’t know what to do. Part of her wanted to confront him directly, while another part considered climbing onto the roof and throwing herself off it. Bart was being coy. He was playing her. He had a plan and Lisa knew that she… Her phone buzzed in her hand. Its screen illuminated with the notification of another text message. Lisa’s heart jumped into her throat. She felt terrified. Her breath was trembling. She slid her thumb across her screen and her phone’s number pad appeared beneath it. Lisa dreaded unlocking her device, yet her thumb pressed firmly on the screen to type in her PIN.
5 2 9 9
Lisa’s apps and icons appeared atop her Gallop Girls wallpaper. She reached her thumb to the top of the screen and pulled down her notification bar. She froze when she saw her brother’s name. He was texting her from his room, enacting the next stage of his plan. Lisa knew she couldn’t run from this. Maybe he was offering her an apology? Or perhaps a promise to take her secret to his grave. Lisa could only hope she would be so lucky. She took a deep breath, and she opened the message.
‘Send Nudes or I’ll show mom what you did with the dog last night!’
Lisa froze. He couldn’t mean… Lisa thought back to the previous night, the night where she had excused herself from dinner. She wasn’t gone that long. It was just a quick fuck. She didn’t let him tie with her and she was back downstairs in a few minutes. Is that when he caught her? How much had he seen? How much proof did he have? Photos? A video? Lisa sighed, it didn’t matter. She sat in silence for over a minute. Her screen faded to black as her phone locked itself from inactivity. Lisa wondered if she could reason with her brother, bargain for his proof. But she couldn’t face him. Not now. Not anymore.
Lisa didn’t know how long she sat on her bed. Her phone remained silent and motionless. Bart hadn’t asked her why she was taking so long. He hadn’t knocked on her door, he hadn’t left his room. Lisa sat up and inhaled deeply through her nose. If she was going to do this, then she should do it soon. Lisa slid off her bed as her feet landed on the carpet. She reached under her dress and slipped her thumb into the waistband of her panties to pull them from her hips. Lisa lifted one leg to step out of her underpants and she sat down on the floor. Her panties hung from her ankle, dragged across the carpet as she spread her legs. Lisa turned on her camera and switched the app into Selfie mode. She set a timer and positioned it between her legs. With her phone in one and her dressed raised in the other, she squeezed her eyes shut as she waited for the shutter.
*click*
Lisa opened her eyes. She raised her phone with her trembling arm. Her smooth yellow pussy was forever captured on her screen. Lisa looked over the photo of her private area. It looked so soft to her, so pure and innocent. Yet less than twenty-four hours ago her petals were stretched around her dog’s cock. Santa’s Little Helper had seen it, smelt it, licked it, and fucked it. And now, Bart would be the first boy that would see it. Lisa opened up her brother’s message and attached the photo as a reply. Her finger hovered over the Send button in fearful hesitation. She closed her eyes again and pushed down on the screen.
The photo was sent.
Lisa dropped her phone and buried her head in her arms. She couldn’t believe she had just done that. Her mind raced with the options and possibilities on what she could have done to avoid such humiliation. Tears began to swell in her eyes as she started cursing herself and her urges. Why couldn’t she have waited yesterday? Why couldn’t she have stuck to her own rules? Why’d she have to risk everything for only a few minutes with her canine lover? The soft sounds of her whimpers filled the air around her. Tears landed in small dark circles on the carpet. Her rash decision last night had ruined her life. Lisa cried into her arms as her phone’s screen lit up. A second message had just come through. Lisa wanted to put her shoe back on and stamp her foot on her phone. She wanted to shatter its screen and crush it beneath her heel. But she picked it up instead. Lisa lifted her head as she typed in her PIN. She wiped her eyes on her arm as she opened the new message.
‘Not bad, but I wanna see some action’
Lisa felt her pussy clench. Action? Did that mean what she thought it meant? Did Bart want her to… Suddenly, the fear of having been discovered didn’t seem so bad. Lisa looked up toward the door. Santa’s Little Helper was on the other side, out there somewhere. Could she do it? Should she do it? Lisa knew that she’d only be giving Bart more leverage that he could use against her, but if he wanted more… he wanted fresh, new pictures… Lisa turned back to her phone. She raised it and her thumbs tapped hastily across the screen.
‘… fine, But you better not show this to Milhouse.’
Lisa tossed her phone onto the bed and got to her feet. She looked down at her panties and bit her lip. A small grin crossed her mouth and she kicked the piece of clothing from her foot. Before she lost her nerve, Lisa marched herself across her room and out into the hall. She glanced at Bart’s bedroom door further down. His door was slightly ajar and she heard his voice call from his room.
“You need a minute, sis?” he asked. Lisa could just tell he had a grin on his face.
“Yeah,” Lisa said, suddenly realizing how dry her mouth was. “Just a few.”
“Take your time, Lis.”
Lisa walked with determined purpose through the house. She couldn’t believe she was even entertaining the thought of doing this for her brother, but the thought of dog cock was now burning within her mind. She wanted it, she craved it. She was going to do it. Without shoes or panties, Lisa pulled open the back door and stepped out onto the patio. Santa’s Little Helper lay on the grass by his kennel. His head rested atop his paws while the faithful dog slept peacefully in the warm afternoon sun. Lisa carefully walked towards her sleeping pet, but Santa’s Little Helper’s ears twitched. He could hear the rustling grass from Lisa’s footsteps and his eyes open as she approached. Santa’s Little Helper immediately lifted his head. His tongue slipped from his mouth as he started to pant, and his tail wagged against the grass.
“Hey boy,” Lisa smiled as she knelt next to him. Santa’s Little Helper stood and pounced on Lisa, pushing her to the ground. The girl laughed as he licked her face with excitement and enthusiasm. But he quickly stepped back and lowered his head to the hem of her dress. Sniffing curiously, Santa’s Little Helper slipped his nose and muzzle underneath the fabric. He was delighted to see that his human lover wasn’t wearing any further clothing. Lisa opened her mouth to speak, but the words became lost in a quivering groan. Santa’s Little Helper had pressed his tongue against her pussy and started licking. The long, moist muscle brushed over the tiny bump that was Lisa’s clit. Her body seemed to tremble at his touch and she surrendered to rolling her head to its side. But Lisa quickly came to her senses and sat up. Her pussy was pulled from Santa’s Little Helper’s tongue as she stood up and stepped back.
“Not here,” she smiled as she scratched her pet behind the ears. "Let's go inside." She turned and walked back to the house, her faithful companion following closely behind her.
It wasn't until Lisa had returned to her room when she realized how bad she was craving this. She closed her door and pressed her back against it, watching as Santa’s Little Helper sniffed the familiar surroundings. His nose quickly found Lisa’s panties on the floor as he picked up her scent. Santa’s Little Helper looked up at her and wagged his tail. Lisa bit her lip as she smiled. She would be taken again. She’d get to feel the animalistic lust of the family pet once more. Lisa no longer cared that she would be giving Bart any more evidence against her. All she wanted was to be mounted again. And if that meant giving Bart more to buy his silence, then she would give him more. Santa’s Little Helper padded over to his owner, his tail still wagging in anticipation. Lisa knelt in front of him and he began to lick her face. Lisa tilted her head to allow his tongue to slide over and all around her mouth. She would feel it slip between her lips with almost every pass. Lisa sat on the floor and reached behind her neck. She removed the clasp on her pearl necklace and pulled it from her neck. After placing it carefully on her nearby shelf, Lisa wrapped her arms around Santa’s Little Helper’s neck and gently removed his collar. She rose from the floor and her dog pressed his nose to her crotch almost straight away. He started sniffing at her damp pussy through her dress. He tried to lick the source of her scent, his tongue lapping over the fabric of her clothing. Lisa didn’t push him away, not again. She held the collar in both hands and lifted it to her neck. She wrapped it around her throat and fed the strap through the collar’s buckle. Lisa smiled as, in her mind; her act had cemented her role. Wearing Santa’s Little Helper’s collar only heightened her experience with her beloved dog. It was how she would submit to him, it was how she saw herself, it was the role that she desired.
Lisa lifted her dress over her head and tossed it aside. Santa’s Little Helper barked, knowing full well what was happening. He sat on the floor, his tail still wagging. Between his hind legs, Lisa’s eyes fell onto his brown furry sheath. It slightly shook with the wagging of his tail. Lisa dropped back to her knees. Santa’s Little Helper started licking her again straight away as Lisa reached down between his hind legs. She started to rub his sheath with her hand. Santa’s Little Helper stopped licking when he felt this familiar sensation between his legs. He looked at Lisa, panting patiently. Lisa could feel his sheath start to thicken as his cock began to grow. Its dark red tip poked out into the air and Lisa rubbed it lightly against her palm. But while one hand worked the dog’s member from its hiding place, Lisa’s other hand was between her legs. She was breathing heavily as she rubbed herself. She moved her longest finger up and down the length of her moist slit, while her hand wrapped around the growing cock. She dipped her finger between her folds, while she started to rub him up and down. Lisa’s finger found her small entrance, the girl cooing as she eased it inside herself. Lisa quivered as she buried her finger down to her knuckle. She kept her gaze locked onto Santa’s Little Helper and eased it slowly back out from her depths and offered it to her pet. Santa’s Little Helper started licking all over, cleaning Lisa’s damp lust from her skin.
“You horny, boy?” Lisa whispered. Her hand was moving up and down along her dog’s shaft. It was warm, firm, and pulsed lightly in her hand. “So am I,” she said. “But I really need your tongue. I need you to lick me.” It turned Lisa on, talking dirty to her dog. She could say the lewdest things to excite her, despite knowing he couldn’t understand.
“Oh, fuck I need you, boy” she groaned.
Lisa stood and walked over to her bed. She sat on the edge of the mattress, spreading her legs apart and watching as her dog’s eyes suddenly became fixated upon her. Santa’s Little Helper gazed at her pussy. He padded forward and pressed his cold nose against her folds, causing Lisa to shiver. He licked her once, then twice, while Lisa reached for her phone. She tried to stifle her groans in her throat as she opened her camera app. Lisa took a quick photo as her dog began to feast on her cunt. Lisa closed her eyes as she finally let her groans escape from her mouth. She dropped her phone on the bed, the photo remaining unsent and suddenly forgotten.
“Nnnnngggghhhhh,” Lisa exclaimed. She could feel the incredible tingling emanating from her pussy. Santa’s Little Helper forcibly pressed his tongue against her folds as he dragged it up the length of her slit, over and over. Lisa rolled her head back and her jaw hung from its hinge. Her breathing had become short and erratic, just like she was panting.
“Oh, God…” she groaned, her dog’s fat tongue brushing over her clit. Her legs were trembling, her feet twitching. But she wanted to go further. She needed more. Lisa moved her hand down to her pussy, pushing Santa’s Little Helper out of the way. She felt so wet, a mixture of her lust and her dog’s drool. Lisa used two fingers to pull her pussy lips apart. She exposed her moist, pink flesh to her dog. Santa’s Little Helper bounded back between her legs and pressed his tongue back against the girl. This is what he wanted, and it’s what Lisa craved. Santa’s Little Helper snaked his long tongue inside the squirming girl. Lisa quickly snapped another picture and tossed her phone back onto the bed.
“Oh God, lick me, boy,” Lisa moaned. Santa’s Little Helper pressed his wet muzzle against her open pussy as if he tried to fuck her with his snout. Pussy juice dripped from Lisa’s crotch and splattered on her covers. She could smell how wet she was, her strong scent wafting around her. Santa’s Little Helper groaned quietly as he licked. He sounded like he could never get enough of the taste of Lisa’s cunt.
“You’re such a good dog,” Lisa whimpered as she threw her head back again. She needed to cum. Lisa wanted the feeling of being licked to last, but she needed the release. Santa’s Little Helper’s tongue slithered inside her pussy depths like a snake sliding into its hole. Lisa’s pussy quivered, it was on fire. Her lungs were filled with her scent every time she inhaled. Her loins whirled inside with hot tingles as each lick pushed her closer and closer…
“Oh God,” Lisa moaned. “Oh fuck…” Lisa didn’t care if Bart heard her. He knew what she was doing. Lisa’s body jerked, almost rhythmically, with each spasm. Her pussy felt like it had exploded with her juice as she came against Santa’s Little Helper’s mouth. Lisa writhed in orgasm. The hot sensation surged through her cunt. She rode it over her dog’s face and nearly blacked out as her body fell backward onto the bed. Lisa lay there, staring up at the ceiling with a satisfied grin on her face.
“Oh, good boy,” she sighed. “Very good boy.”
Lisa slid off the bed. Santa’s Little Helper quickly stepped aside so Lisa could stand, running around in a tight circle before turning back to face her.
“Sit, boy,” Lisa said, and her dog immediately obeyed. She felt a sudden sense of irony; wearing his collar while she issued simple commands.
“Roll over,” Lisa said, and Santa’s Little Helper obeyed once again. The greyhound rolled onto the floor and lay on his back. He panted happily with his legs sticking up into the air. Lisa started aggressively rubbing his belly with one hand, causing his legs to twitch and his tail to wag happily across the carpet, while she grasped his cock in her other hand. She squeezed Santa’s Little Helper’s shaft in her fingers and started to rub him up and down. Lisa quickly leaned forward and placed her lips on the tip. She gave his member a kiss and his precum smeared across her lips. Lisa wasn’t sure if she wanted this more than her dog at this point. She kissed his cock again and parted her lips around it. The dog prick slid almost effortlessly into her mouth. Santa’s Little Helper began to hump against her mouth, almost like he was throwing his back up off the floor. His hot cock seared against Lisa’s lips and tongue, while Santa’s Little Helper jabbed against her tonsils and made Lisa gag. But Lisa held firm, she didn’t pull away. His cock twitched with precum oozing into her mouth. Santa’s Little Helper’s cock tasted salty and bitter, it was musky and bestial. Lisa couldn’t get enough of it. She pressed her tongue to its surface and licked him as she slid her head up and down his length.
Santa’s Little Helper’s cock flexed and quivered in her mouth. To Lisa, it felt like he seemed to get hotter and harder the more she blew him. Her mouth seemed to be pulsating and her lips swelling around him. Santa’s Little Helper humped faster and harder against her mouth. He growled and whimpered. Lisa sucked him like her sister sucked her bottle. Her lips pursed around his cock, her tongue licked and slid across every inch it could reach. Santa’s Little Helper let out a soft yelp. It was Lisa’s only warning that she was making him cum. His cock swelled in her mouth and twitched against her tongue. Santa’s Little Helper flexed and Lisa’s mouth and throat were suddenly flooded with his cum. She coughed as she choked, but kept her lips on his member. Stream after stream of slimy seed kept shooting against the back of Lisa’s throat. Lisa drank deeply in Santa’s Little Helper’s cum as she slowly pulled herself off his shaft. She held his cock firmly as the last of his climax sprayed across her face.
Santa’s Little Helper rolled his head to the side. His tongue rested on the carpet as it hung from his jaw. He panted heavily, his legs twitched lightly in the air, and his cock was still hard in Lisa’s grasp. Lisa sighed, her want for dog cum was temporarily satisfied. She kept her hand on Santa’s Little Helper’s cock and softly stroked him. Her fingertips squeezed gently into his flesh, keeping her grip firm. She reached for her phone and switched on her camera for another photo. Lisa placed his cock back in her mouth and looked up at her phone. She smiled as her pose was captured on the screen.
“You think I’ve got enough photos?” she asked her dog. Santa’s Little Helper lifted his head, still panting. Lisa kept stroking him as she looked through her gallery. “Maybe I should take one more. You’ve got another round in you, right boy?” she asked him. One of Santa’s Little Helper’s hind legs twitched in the air.
“That’s a yes,” Lisa smiled. She got to her feet and swung her leg over her dog. She carefully lowered herself over the tip of his cock, pausing as it kissed her pussy lips. Lisa rolled her hips as she painted the head in her lust. Her pussy smeared its moisture over the cock before the tip pierced her lips. Lisa bit her lip as she felt her dog at her entrance, and her eyes rolled to the top of their sockets as she eased herself down upon him.
“Oooooh,” Lisa quivered. Her pussy was stretched open as she lowered herself down upon his length. Inch by inch, Santa’s Little Helper’s cock vanished inside of her young cunt. Her inner walls hugged and squeezed on the canine shaft as it slowly filled her, and it wasn’t long until her pussy was kissing his knot. Lisa sat carefully atop Santa’s Little Helper. She wanted to take a moment and enjoy being stretched open by him. His cock was a snug fit inside her, and Lisa’s inner muscles clenched and squeezed around him.
“Ooooh, you’re such a good dog,” Lisa whispered, her head back and her eyes closed. Lisa grabbed her phone and opened her camera. She knew exactly what her last photo should be. Leaving it on the floor beside her, Lisa began to ease herself up her dog’s cock. She pushed herself back down, starting to ride her beloved pet. Lisa began almost bouncing on top of Santa’s Little Helper. Her pussy lips rubbed against his bulging knot each time she sunk down.
“Gimmie that knot,” she groaned. Lisa forced herself against it a little more each time. “Oh, fuck I need you, boy.” Lisa leaned forward and wrapped her arms around her dog’s neck. She closed her eyes and buried her face into his fur, bouncing on his cock and pushing herself closer and closer to tie with him. Her pussy was on fire as each jab she forced would bring her closer to orgasm. When she felt herself stretch enough, she reached for her phone. Lisa sat up and pointed the camera at her crotch. She paused, feeling his knot at her cunt and took the photo. Lisa quickly switched to video and hit the record button with her thumb. She closed her eyes, bit her lip, and pushed herself down. Her phone caught her pussy swallowing the bulge. Lisa dropped her phone as she came. Maybe it was the act, maybe it was the idea. But Lisa tied herself with Santa’s Little Helper. Her dog was buried inside of her as deep as he could go. She was locked on top of him, her body screaming and trembling with orgasm.
“Come on, boy,” Lisa groaned. “Cum inside your bitch.” Tied together, Lisa was limited to short, sharp bounces. Her pussy rubbed against Santa’s Little Helper’s fur as she rode him.
“I need your cum,” she was almost pleading to him. “I need you to breed me.” Lisa wrapped her arms back around her pet, her phone laying forgotten on the floor. Her legs were stretched around Santa’s Little Helper with her toes bent against the floor. Santa’s Little Helper let a soft howl escape his mouth, and Lisa felt a warm splash of cum deep inside her. Santa’s Little Helper twitched and jerked as he shot his hot, sticky seed deep inside of Lisa Simpson. Her pussy hugged his cock, almost milked it out of him. His tail wagged furiously across the floor behind him, his hips bouncing off the floor as he came inside her.
“Good boy,” Lisa panted. She looked lovingly into her dog’s eyes. “Very good boy.” Lisa pressed her lips against Santa’s Little Helper’s mouth and forced a kiss upon him. She took his tongue inside her mouth, letting it explore and dance over her own.
“I love you so much,” she whispered to him. It didn’t bother Lisa that she had fallen for the family dog, she didn’t care. It was what she wanted, what she craved. But, despite that, she still wanted to keep it a secret. Lisa reached for her phone and attached the photos into a text message. They popped up in the message bar one by one; Santa’s Little Helper licking her pussy, his cock in her mouth, and his knot at her cunt. Lisa pressed her finger against the screen. Without fear or anxiety, she sent the photos to her brother.
“Holy…” Lisa heard Bart yell through the wall of her bedroom. His reply came through almost straight away.
‘.… This isn’t what I meant by action’
Lisa didn’t give her response a second thought. She loved Santa’s Little Helper, but she was also still horny. She knew that Bart would eventually want more from her to buy his silence, so Lisa decided to offer him as much as she could. Lisa quickly typed out her last message:
‘I guess you don’t want to join in then huh?’
Lisa dropped her phone onto the floor. She didn’t care what would happen now. She was with the one she loved, the animal she was addicted to. Lisa rolled her hips over his groin and hugged his cock within her. She wrapped her arms around Santa’s Little Helper’s neck and she kissed him again. Lisa closed her eyes as her phone lit up with Bart’s reply.
‘…. I’ll be there asap’
