I walked into the house after work and heard the laughter right away. My sister Lisa was throwing one of her parties again, but this time the living room was full of women passing around vibrators and dildos like they were party favors. She had told me it was just drinks with friends, but the table was covered in sex toys, lube bottles, and open boxes from some online shop. I should have turned around, but my cock was already twitching in my jeans when I saw her holding a thick realistic dildo up for the group to see.
"Check this one out," Lisa said, her voice loud and filthy. "It vibrates and it has these balls that slap against your clit when you fuck yourself with it." The women around her laughed and one of them grabbed it, turning it on and pressing the head against her own palm. My sister spotted me in the doorway and grinned instead of kicking me out. "Hey, look who showed up. My brother wants to watch the demo."
They didn't stop. Lisa told the group I was cool and they kept going, pulling out more toys. One woman stripped off her top and let another rub a bullet vibrator over her nipples while everyone watched. My sister leaned back on the couch and hiked up her skirt, showing she wasn't wearing panties. She grabbed a curved G-spot toy and slid it straight into her pussy, moaning loud enough for the whole room to hear. "Fuck, this thing hits the spot every time," she said, pumping it in and out so we could all see her juices coating the silicone.
I stayed in the corner, stroking my cock through my pants while they passed toys around. Lisa looked right at me and spread her legs wider. "You like watching your sister fuck herself with this?" she asked, not even whispering. The other women egged her on, one of them reaching over to rub Lisa's clit while she fucked the toy deeper. The room smelled like pussy and lube, and the sounds of buzzing vibrators mixed with wet slaps as they all started playing.
Lisa pulled the toy out and tossed it aside, then crawled over to me on her hands and knees. "Get your cock out," she said, raw and direct. "Everyone here wants to see you fuck me after we all get off with these toys." I unzipped and my dick sprang free, already leaking. She wrapped her hand around it and licked the head, then turned around and backed her ass up against me. "Shove it in. The girls want a live show."
I slammed into my sister's wet cunt while the rest of the party watched and used the toys on themselves. Lisa pushed back hard, taking every inch and talking dirty the whole time. "That's it, fuck your sister's pussy. Make it sloppy so they can see your cum drip out of me." One of her friends knelt beside us and pressed a vibrator against Lisa's clit while I pounded her. Another woman sucked on Lisa's tits, biting the nipples until she screamed and came hard around my cock.
We didn't stop there. Lisa pulled off me and had two of the women lie on the floor with their legs spread. She handed them bigger dildos and told them to fuck each other while she watched. Then she dropped to her knees and sucked me again, tasting her own pussy on my shaft before standing up and bending over the table. "Come on, fill me up. I want your load in front of everyone."
I grabbed her hips and drove back inside, fucking her raw and fast the way she wanted. The other women were all moaning now, some coming on the toys, others fingering each other while they stared. Lisa reached down and rubbed her clit until she came again, her pussy clamping down and milking me until I unloaded deep inside her with a loud groan. Cum leaked out around my cock as I kept thrusting through it.
After that the party turned into a full-on orgy with the toys. Lisa stayed bent over while one friend licked my cum out of her and another slid a double-ended dildo into both of them. I stayed hard and took turns fucking whichever woman wanted it, but my sister kept pulling me back to her, telling me to use her holes while the others watched. By the end of the night the floor was sticky with lube and cum, the toys scattered everywhere, and Lisa was lying on the couch with her legs open, letting everyone see the mess I'd left in her.
She looked over at me with a satisfied smirk. "Next time you can host the demo," she said. The women laughed and started packing up the toys, but I knew this was only the start of what my sister had planned.
