My sister Jenna was 22 and always horny as hell. One Friday night our parents were out of town and she came into my room wearing nothing but a thin tank top and tiny cotton panties. "Can't sleep," she said, climbing right onto my bed. She didn't ask, just straddled my thigh and started rubbing her pussy against me.
I could feel the heat of her cunt through the fabric.
She moved slow at first, grinding her hips in small circles, pressing her clit down hard. "Fuck, your leg feels good," she muttered. Her panties were already damp. I watched her ass flex as she humped me, her tits bouncing under the tank top. My cock got rock hard in seconds.
She noticed and shifted, lining her pussy up with the bulge in my boxers. Then she really started humping. Long, dirty strokes, dragging her soaked slit up and down the length of my dick. "Yeah, just like that," she whispered. "Rub that big cock on my cunt." Every pass made her panties wetter until I could feel the slick heat of her lips through the cotton.
I grabbed her hips and pushed up to meet her. We dry-humped like animals, the bed creaking, her breath coming in short gasps. "Harder," she demanded. "Make me feel it." She leaned forward, her tits pressing against my chest, and kept grinding. Her clit was swollen and she worked it right against the head of my cock, soaking the front of my boxers.
After a few minutes she yanked her panties to the side. Her bare pussy lips slid along my shaft, hot and slippery. "I need to feel you," she said. She humped faster, coating my cock with her juices. The head kept catching on her entrance but she didn't let it slip in yet. She just kept rubbing, clit bumping against me with every thrust.
"Fuck, Jenna, you're dripping," I growled. She moaned louder and pressed down harder, her cunt lips spread open around my dick as she humped. I could hear the wet sounds every time she slid forward. Her thighs started shaking. "I'm gonna cum like this," she panted. "Don't stop."
She rode me faster, short frantic humps, grinding her clit right on the ridge of my cockhead. Her pussy clenched and she came hard, soaking my boxers even more, her whole body jerking. But she didn't get off. She kept moving, slower now, smearing her cum all over me.
Then she reached down, pulled my cock out, and lined it up. "Fuck me for real," she said, and sank down. Her tight cunt swallowed every inch in one long slide. She started humping again, this time with my bare cock buried inside her. Deep, rolling motions, her hips working in circles, clit grinding against my pelvis every time she bottomed out.
I fucked up into her, meeting every grind. The wet slap of her ass hitting my thighs filled the room. "Your pussy's so fucking tight," I told her. She clenched around me and moaned, "Keep talking dirty, brother." I slapped her ass and she humped faster, riding me like she was trying to break the bed.
We switched positions. I put her on her back, legs spread wide, and started humping into her missionary style. Short, hard thrusts that kept my cock deep while my pelvis rubbed her clit with every stroke. She wrapped her legs around me and pulled me in. "Don't pull out," she begged. "Fill me up."
I pounded her until she came again, her cunt pulsing around my dick. Then I flipped her onto her stomach, pulled her hips up, and humped her from behind. Doggy style but low, my chest against her back, my cock sliding in and out while I ground my hips in tight circles. She reached back and spread her ass cheeks so I could get even deeper. "Use that pussy," she said. "It's yours."
I came hard, shooting deep inside her while she kept pushing back, milking every drop. We stayed locked together, my cock still twitching in her cum-filled cunt. She gave a few lazy humps, pushing my load around inside her.
Afterward she didn't move off me. She just lay there, my softening cock still inside, and gave one last slow grind. "We're doing this again tomorrow," she said. "And the next night. And every time Mom and Dad leave."
I was already getting hard again inside her. She felt it and started humping once more, slow and filthy, working my cock back to full stiffness without ever letting it slip out. Round two started exactly the same way the first one had: with my sister grinding her wet pussy all over me like she owned it.
