As I was walking towards Maca's place with the three girls I just met, I started feeling weird. Kind of good weird. I felt my cock stiffening, and my sexual desire growing rapidly. I couldn't understand why, but at this point I didn't care, I just couldn't wait to get there and let them have their way with me.
When we got to the apartment, there was an ecstatic uproar as the three girls brought me in. There were a lot of girls there, all dressed in tight, short dresses and high-heeled sandals, I was drooling instantly, and my cock felt like it'd burst.
Apart from Maca, who sat on a chair in the middle of the room, awaiting my performance, I saw a few girls I also knew from work, as well as Jelena (of course she'd be there), and right there, with her, was her friend, my cousin Milena. Crap.
I hated the idea that I'd soon be getting undressed in front of my cousin, even though she hopefully wouldn't know it was me. After all, she seemed a bit tipsy (they all did), she's never seen me naked, and my face was covered.
What puzzled me was that, even though I didn't like the situation, my arousal was not going away. I was still rock hard, and horny to the point I had trouble thinking straight.
Moments later, the lights got dim, and "It's Raining Men" started playing. I started dancing as seductively as I could. I guess years of dance classes paid off, because the audience sounded impressed.
I danced in circles around the chair Maca sat on, gradually getting closer and closer to her. Contrary to all the other girls in their fancy dresses and heels, Maca was wearing just an oversized T-shirt with "bride to be" written in big letters over the chest, and she was barefoot.
As I dramatically took off the top of my costume, she reached out with her foot and lightly slid it across my crotch, sending sparks through my whole body.
I kept dancing closer to her, and when I got close enough I turned my back to her and ripped off my pants, while pushing my ass close to her face. She gasped in surprise when she saw the buttplug, then slapped my ass and called me a slut.
Next I felt her pulling the thong up my ass, giving me a painful wedgie. I instinctively reached back, and felt her cuff my hands behind my back.
She then extended her leg under my crotch, while grabbing my thong with her hand, and started pulling me back and forth, forcing me to grind on her leg to prevent the thin material from being either ripped off or wedgied into my ass.
All the girls were very amused by my performance, and I was getting close to blowing my load. After a while, she stopped pulling on my thong, and I just kept grinding on her leg, too horny to care about anything.
