“Are you sure? Now’s your chance to back out,” Will breathed, watching his baby sister below him. She looked up at him with hungry eyes, and pulled his face down to hers. Tess cupped his jaw as she planted a wet kiss on his lips, pushing her tongue into his mouth eagerly. His cock twitched at her entrance, and he fought every urge to not slam his member into his virgin sister’s hole then and there. He wanted nothing more than to bury himself in her, over and over, until he’d dumped all of his pent-up load deep into her waiting womb. It occurred to him, then, cock dripping precum into her waiting cunt, that he had no idea whether or not she was on birth control. The next thing that he realised was how much harder that made him, and he swallowed the idea that he might actually *want* her to get pregnant. Tess pulled back from the kiss, hand still locked on the back of his neck and holding him.
“I want you to be my first,” she panted. “I want you to *fuck* me.”
Will lost it, then. Maybe it was the cursing coming out of his baby sister’s mouth, or the way her very eyes seemed to beg him, but he couldn’t hold back any longer. He grasped his dick, guiding it between her folds, and pushed his way inside. Tess gasped, unprepared for the feeling of being so full all of a sudden. *God, this is nothing like my hairbrush*, she thought, rocking her hips a little to accommodate the intrusion. Will paused, letting her move around him.
“Are you okay?” he asked, his cock throbbing madly and desperate to continue. Tess nodded quickly.
“Yeah, it’s just…uh. Bigger than I expected. How far in are you?”
“I think I’m at your hymen, but I’m only a few inches in.” he replied, looking down at where they connected. He could feel the barrier with the head of his cock, but it was barely inside of her. *Jesus, she’s already so tight*, he thought, and wondered if he’d be able to fit inside her.
“It’s okay, you can keep going,” she urged him on, pulling him in for another sloppy kiss. Will pulled back slightly, but not all the way out.
“I’m going for it, then,” he said, breaking their kiss and taking a breath in. Tess nodded, her hands trailing down his tan chest and resting on his hips, pulling gently to encourage him. He waited, looking down at the beautiful girl spread out beneath him. He couldn’t believe she was finally letting him fuck her, and that she was a virgin as well.
Will placed one hand on his cock to guide it, and another on the pillow beside Tess’s head to stabilise himself as he bore down, breaking through his sister’s hymen and burying himself to the hilt. A long, desperate moan escaped Tess’s lips as his pelvis came to rest on top of hers and his weight ground his pubic bone onto her clit. *He’s really inside me*, she thought. *I’m finally fucking my brother, and he’s inside me bare! And I’m not on the pill!* Her cunt squeezed involuntarily at the realisation, the unconscious motion milking her brother’s cock as it settled inside her, the tip pushing hard against her cervix.
“Holy fuck, Tessie,” Will moaned, “your cunt’s so tight it’s unreal,”
“Will,” Tess managed, the pain of her losing her virginity quickly being replaced with a new, better sensation. “you can start moving, if you want.” Her eyes were closed, but her hands gripped his hips desperately. Will knew what she wanted—no, what she needed—and pulled halfway out before slamming back into her. He could feel his cock come to rest at her womb and she moaned, loudly into his chest. He took that as a good sign, and continued the slow, rhythmic pumping as he pounded his sister’s cunt.
“Fuck, Will, why are you so *big,*” she bit her lip, her breasts bouncing in time with his thrusts. “I can’t believe you’re finally fucking me,” she threw her head back on the pillow, her arms resting around his shoulders. In time with Will’s thrusting, Tess bucked her hips upward, pushing him further into her depths. She could feel her first orgasm building, so she reached a hand down and began circling her clit. He felt a familiar pressure begin to build at the base of his spine.
“Tess, baby, I’m getting close.” he warned, but she didn’t slow down.
“Oh, god, I think I’m close too,” she whined, right as Will picked up the pace. “I want you to come inside.” *Oh, shit*. He could feel her begin to tighten around him, pulling him deeper as he went. *Fuck, there’s no way I’m gonna be able to pull out*, he realised, and began to slow his movements, but it was too late. Besides, his baby sister had other plans.
“Wait, Tess, I’m gonna—” Before he could warn her, Tess shook with her first orgasm, clamping down on his already sensitive cock. The sudden grip of her tight pussy on his member sent him over the edge, and he tried to pull out quickly, but Tess had wrapped her legs firmly around his waist, locking him inside of her. There was nothing Will could do as the climax washed over him, and he collapsed on top of her helplessly as he dumped rope after rope of white hot cum into her fertile little belly. For a moment, they lay semi-still, panting hard as they both came down from the high. Will was still buried all the way inside of Tess, the last few spurts of cum leaking out of him.
“Fuck, Tess. I came inside you!” She nodded, but she didn’t let go of her legs. Instead, she squeezed him closer, pulling him down and clenching his cock inside her again.“Mm, I can feel that,” she agreed, the warmth of his cum spreading in her belly. She adjusted her hips, trying to keep him in as his cock twitched with the last of its baby batter. She rubbed a hand across her taught tummy, looking up at him with legs still wrapped tightly around his back. “You didn’t protest too much,” she teased. Will shook his head.
“What if I got you pregnant?” he asked. As much as he hated it, his cock hardened accordingly when he asked. She felt it, too, and smiled deviously.“I think you’d have to try again to be sure,” Tess teased. Will locked eyes with her, pushing his hips forward and grinding into her. She moaned, hand still laying across her stomach.
“Well, if that’s the case,” Will leaned back, placing a hand on each of her hips and adjusting her pelvis so that she was leaned back slightly. “We’ll just have to try again, won’t we?” He quickly grabbed a throw pillow and shoved it below her hips. He hoped that the load he’d dropped would be enough to knock her up, but he wanted to be absolutely sure. After all, it wasn’t every day you had the chance to bareback your virgin sister and impregnate her, and he wasn’t about to lose out on any chances.
He rubbed her flat stomach, imagining what it would look like in a few months. What she would be like, pregnant with their child. Tess, with her perfect curls, her modest breasts heavy with milk and her belly, round and gravid, grinding against his as they fucked madly. The image was nearly enough to make him come again, then and there, but he wanted to save it for where it was needed most: deep in his sister’s unprotected tummy.
