"No," he said, "I know, it's okay. Shhhhh..." He ground against her, unable to control himself. She was so hot and she had him so hard that he couldn't think straight. "We love each other, and you shouldn't have sex with someone you don't love. We care about each other, and we wouldn't hurt each other."
He was panting slightly now. "Fuck, I love you, Linds, you're so hot. I just see you around the house and you're barely wearing anything and it drives me crazy. I need to have you."
"Don't say that!" she yelped, tearing up, "Let me up, I won't tell anyone, I swear. This is really fucked up!"
"It's too late for that, little sis, I can't help it," he groaned, with a glint in his eye, "I have to fuck you." He adjusted his weight, holding down both her arms with one of his, so that he could plunge the other hand down the front of her panties to violate her pussy.
"It's both our first times Lindsay, it'll be so special," he rubbed her wet clit in little circles, making her jump involuntarily. "Linds," he purred in her ear, "come on, baby sis, relax. I'll be your first. I'll make you feel so good."
And he was making her feel good. He had skilled hands that teased her opening, sliding across her slick labia and sensitive clit. His fingers didn't penetrate her yet, but rubbed up and down until her pussy was dripping onto the couch cushion below her. She squirmed, trying not to moan. What if her parents saw her pussy stains on the couch? "Let me up!" she gasped.
Then he plunged two fingers inside her, slowly but firmly. Her cunt walls were velvety smooth and gripped him incredibly tight, even just around two fingers. He buried them in her up to the last knuckles, and began kissing her neck. He nuzzled her behind the ear, then bit her softly, where her neck met her shoulder. She moaned involuntarily, and her body relaxed slightly, allowing Davey to pull his fingers halfway out of her, curling them upwards to brush her g-spot. He could tell her body was responding well, although she was still moaning "no", so he continued kissing her neck as he slowly finger fucked her.
"Fuck!" he breathed into her ear, "I can't believe my fingers are inside you, Linds, you're so perfect, baby sister." His cock had gotten so hard and swollen that it was physically hurting him now. He shoved a third finger inside her, stretching her pussy a little wider and making her cry out, then left them buried inside her for a few seconds. He paused his finger fucking to pull down first her soaked panties and then his boxers, leaving nothing in between them.
He couldn't believe it, it was the stuff of his dreams. He had his hot little sister pinned down under him, dress around her waist, panties around her ankles. His massive hard-on pointed straight at her naked slit, throbbing.
"What are you doing??" she shrieked, "at least get a condom!" But David felt like an animal now, not even listening to Lindsay's words. All he could think about was fucking her as hard as he could, forcing her to take his cock up her sweet tight cunt. He rubbed the naked tip of his cock across her dripping pussy lips, and finally, FINALLY, forced the head of his cock inside her.
She howled at the intrusion, trying desperately to pull away. David almost lost his grip on her, so he let go of her arms and grabbed her around the neck. Looking into her green eyes, he pulled his cock out, then firmly pushed back in, succeeding in squeezing another inch or two of his fat cock into her. It felt like heaven. She was so incredibly soft, more than he could have ever imagined, and her pussy gripped his cock in a hot, wet vice, almost causing him to cum instantly.
He closed his eyes, not wanting to cum so soon. He squeezed around her neck with both hands, partially cutting off her breathing, but being careful not to crush the front of her throat. He at least had to get all the way inside her! He took a deep breath and thrust hard into her petite body, stretching her virgin pussy painfully wide for the first time ever.
She screamed, and Davey was certain that if their house was just a little bit smaller, the neighbors would have heard her. "Davey," she sobbed, "you can't, you're hurting me!" Her tears made him feel a little guilty, but it felt way too good to stop. He shushed her, kissing her neck and sending shivers down her spine.
"I don't give a shit what you say, Lindsay, I'm going to use your little body either way. Be a good girl and accept what's happening, and it'll feel better for you. I promise." He started pumping slowly in and out of her insanely tight pussy.
Lindsay screamed in frustration. She couldn't believe that her own big brother was raping her. And to make things worse, it was starting to feel good. She could still breathe okay, although he had one hand still around her neck. His other hand was roaming all over her body, rubbing her smooth stomach and tits, then gently stroking her clit. He settled into a steady rhythm, moaning in pleasure as he fucked his baby sister raw.
Her sobs and screams became gasps as she felt new sensations hit her. David's thick cock was filling her up entirely, rubbing against her g-spot every time he bottomed out, driving her crazy. She felt her hips shift automatically as her body opened up to accept his cock to an even deeper spot. She had never been fucked before, by anyone, and she couldn't believe how amazing it felt. She struggled to hide her reaction, still whimpering "no's" softly with each thrust.
"That's a good girl," he said, reveling in the way her pussy contracted around his cock, milking it. Her breaths were coming in short gasps now, and her legs were trembling. "Oh God," David said out loud, trying to control himself because it felt like her pussy was going to force his cum out. He grunted, increasing his tempo and thrusting into her harder now. A slapping noise filled the room, as his balls hit her ass with every thrust.
She squealed as the thick base of his shaft stretched her abused hole even further open. He was thrusting so hard, he had pushed her up against the end of the couch, and she felt like she couldn't take it anymore. They were both gasping and panting now. David's tan, fit chest and arms looked good above her as he fucked her relentlessly, and while looking up at him, Lindsay felt a sudden rush of warmth. She screamed as she came, clenching her cunt around David's cock. "Oohhhhhhhhh, Davey, owwwwww! OH MY GOD!! Daveyyyyyyyy!"
As she gasped, recovering from her orgasm, Lindsay realized that it had sent David over the edge. His eyes glazed over as he pumped into her roughly, and she knew he was about to cum, without a condom, into her unprotected pussy. "Davey, PULL OUT NOW!" She pushed him, hard. "You don't have a condom on! I'm not on birth control, please, Davey, don't!" Her shoving was ineffective - David was at least 50 pounds heavier than her, after all - and he kept thrusting into her raw cunt. "No, Davey!" But he wasn't listening to her, or didn't care, because he unleashed his cum inside her.
David grunted as the first splash of semen shot out of him and splattered against her insides. He pulled back for a second, then speared into her again, shooting another spray of cum as deep as he could, right up against her cervix. He held her there, grinding his hips against her, as spray after spray of hot cum defiled her virgin hole. He surprised himself by how much he came, way more cum than when he jerked off in his room. He slammed into her hard as he felt each jet spurt into her, filling her up so full of cum that it was starting to leak out with each thrust.
With a few last hot sprays of potent cum, David finished up. Lindsay could feel the hot, slimy sperm gushing around inside her, and she tried again to pull away from her big brother, with tears in her eyes. She felt dirty and wronged, and now she was filled with his dirty cum, which could easily get her pregnant.
David held his little sister close, panting. He rested his body weight on top of her, crushing her down into the couch cushions and keeping her in place. He kept his spent cock planted deeply inside her pussy, bottling his cum inside her, pushing it deep into her recesses. He kissed her neck, little kisses up and down it, and stroked her gorgeous hair.
Lindsay was humiliated as David kept her pinned for several long minutes, leaving his cock in her and keeping her pussy stretched open, until he was completely soft. Then, he got up, kissed her softly on the forehead, and strutted down the hall to take up the shower once more.
