Volume 7
Lisa stirred in her slumber. The dim morning light filled the room through the closed curtains and bathed everything in a very dark, yet soft orange glow. Lisa yawned and rubbed the sleep from her eyes as she sat up. The covers slid off her nude body as she looked over at her brother, still asleep and snoring softly. Lisa’s hands rested upon her massive stomach. She was would turn seventeen-years-old in a few months, and become a mother in a few weeks. Still a teenager and she was about to give birth to her first child. Lisa lay back in the bed, feeling the slight chill against her body. She covered herself back up and lay against Bart. After Marge catching them in the act of their lovemaking when they were younger, she approved of their relationship after joining them. Marge was able to convince and explain to Homer what had been happening (not including herself in the story), and they bought a nice big double bed for them both.
Lisa’s hand wandered down Bart’s body and gripped his hard shaft. Lisa preferred to wake her brother with her mouth around his cock instead of her hand, but her pregnant belly made it difficult. She slowly started to jerk him off and a soft groan escaped Bart's lips. Bart rolled onto his back, no longer snoring, but he still didn’t open his eyes.
“I know you’re awake, Bart,” Lisa whispered into his ear. Bart was doing his best to stop a small smile from creeping across his lips. During the later months of her pregnancy, Lisa’s libido had become stronger than usual. She felt the urge to be fucked almost every day. Fortunately, if Bart wasn’t around, Homer was. And of her father and brother were busy, there was always a willing cock somewhere in the schoolyard. While she considered herself to be ‘with’ Bart, neither minded the other sleeping around occasionally. It was that sleeping around was what had knocked her up in the first place. There was Bart, Homer, Milhouse, Nelson, Carl, Krusty, and Reverend Lovejoy (with whom she shared a foursome with Bart and Jessica). Lisa knew that any of those men could be the father of her unborn child. She severed ties with everyone but her brother (and Homer, occasionally) when she fell pregnant. Lisa found it exciting not knowing who the real father was, and both she and Bart agreed not to try and find out. But Lisa longed for it to be her brother's child. She had slept with Bart more times than anyone else. Whoever it belonged to, Bart had promised that he’d treat the baby it as if it were his own child.
Lisa rolled over onto her side away from Bart and felt his hand seeping over her bulging belly, his morning wood grinding against her ass.
“I knew you were awake,” she giggled as she rested her hand on his.
“Morning, sis,” Bart whispered as he kissed her neck. “How’s our baby doing?”
“Kicking... and hard.” Bart just smiled as he felt the tiny bumps protruding from inside Lisa’s belly. He used his other hand to adjust himself a little, pushing his hard shaft between her legs and rubbing up against her slit.
“Fuck, sis. I can’t believe you’re actually going through with this. But as soon as you give birth, I’m pumping that womb of yours full of cum again. I’m going to make sure the next one is mine.” Lisa shuddered at Bart’s words, lifting her leg as she felt his shaft. Bart pulled the covers off them both, holding her leg up and slipping pushing himself inside his sister’s pregnant body.
Lisa quivered as Bart started to fuck her; both siblings had become incredibly turned on with pregnancy sex over the past few months. The bed slowly rocked beneath them as Bart pushed his hips up against his sister.
“Fuck... fuck me, brother,” Lisa whimpered as Bart picked up his pace. Lisa turned her head to meet his, their lips and tongues meeting in a passionate and lustful kiss. With Bart’s spare hand, he pushed it under Lisa. While he propped himself up on his elbow, his hand grabbed Lisa’s chest from underneath and his fingers were tugging and pinching her nipples. Lisa started to writhe against him, pushing back into his crotch. Bart pushed his head down to her neck, kissing and biting it. He knew that this is what drove Lisa wild. The girl shuddered as she gripped the sheets. She was being fucked, having her nipple teased and her neck bitten... all by her own brother. She came almost straight away, her whole body twitching and shaking around her brother’s shaft. But Bart wasn’t far behind. He grunted and pushed himself inside his sister as far as he could.
“Fuck Lisa! I’m cumming!” he cried into her neck. Bart’s cock twitched as he sprayed his thick seed inside his sister. Lisa could feel that warm and sticky feeling shooting and spreading around her inner walls. Both Simpson children lay on the bed panting, Bart’s seed now swimming inside his sister. Without pulling out, Bart reached down and pulled the covers over them both, snuggling and lightly humping against Lisa. In the afterglow of their fuck, they shared another kiss as they just lay in their warm bed.

Lisa finally made her way downstairs. Both Bart and Homer were already eating breakfast, but both their gazes fell upon the glowing Lisa as she walked into the kitchen.
“Morning, daddy,” she hugged her father as she kissed him.
“Good morning, sweetie. Sleep well? The boy didn’t keep you up all night?” Homer smirked, his hand resting on his daughter’s ass. Lisa’s pregnancy had complicated life around the house quite a bit. While both Homer and Marge knew that Bart and Lisa were quite intimate and knew Bart might be the father, they didn’t know about each other's involvement. Homer had no idea that Marge had been sleeping with them for several years, despite Bart’s many attempts to knock his mother up. And Marge didn’t know that Homer had been sleeping with Lisa, and it was possible that he was the father. But Lisa knew. It turned her on that she might give birth to her own brother or sister.
“Well, not all night,” she grinned, pushing her ass back against her father’s hand. Bart watched as Homer’s other hand slipped off the table and he heard the unmistakable sound of a zipper being pulled down.
“You shouldn’t be on your feet so much, Lisa. Not in your condition. Why don’t you sit on daddy’s lap for a bit?” Lisa nodded eagerly as Homer pushed his chair out a little, letting his pregnant daughter onto his lap. From Bart’s point of view, he saw Lisa’s hand adjusting and holding something below the table before she slowly lowered herself down. He heard his sister groan as their father’s cock slipped easily inside her.
“Sorry Homer,” Bart said, leaning back on his chair and resting his hands behind his head. “I’m pretty sure I made a mess in there earlier this morning.” With his hands firmly around his daughter’s hips to push her up and down and his cock deep in her warm and sticky cunt, Homer looked over at his son across the table.
“Doesn’t matter, boy. It doesn’t bother me at all.”
