You are standing behind me in the crowded train, your hand accidentally brushing against my thighs. The influx of people from each station pushes you closer and closer to me. I turn around to face you, and with each push from the crowd, my breasts press against your taut chest. You can feel my nipples poking against your shirt. And I can feel your growing erection grinding my inner thighs.
I free my hand of my handbag, and rub your crotch until your cock begs to be free. I tease your fly open, and you spring out to my delight.
My fingers play with your precum, and then I slide my skirt up my thighs. I guide your cock between my legs, and you start rocking your hips, with the help of the crowd. You can hear my muffled moans against your chest, and that only excites you more.
You grab your cock and jam it into my wet pussy and I cry out in sheer pleasure. Prying eyes see no more than a girl resting her head against her lover’s chest.
You glide in and out with ease until you can no longer suppress the mounting thrill of getting caught. You spend your last burst of energy, and with an erotic groan, your cock erupts within me.
The train reaches the last stop, and as everyone gets off, I pull my skirt back down, and lick my fingers while I watch you wink an eye, and walk off, as if it was just another day in the train.
