Mean girls - FF/M
The ingenuity of girls when it comes to tickle torturing an overconfident guy can be so... simple yet so cruel.
Tied down, his worst spots trailed upon and explored until he's hard. It feels so good. That's what he thinks.
Reward? For him? Is his thought when his cock is smothered inside one of the girls D cups.
But they're not moving. Those soft, teasing pillows are only there to hold his weakest spot still, as a feather's tip descends upon his cock's own. Breaking into laughter, he hears the condescending "awww, poor baby is ticklishhhh" of the girl holding his sensitive, wet glans hostage.
Maintaining eye contact, the feather humiliates the poor guy by eliciting giggles and desperately thrashing around, inevitably thrusting up and down his soft, smooth and embarassingly stimulating prison.
The girls seemed to be enjoying this oh so much. "Awww, are you taking advantage of meee? Giving yourself a titjob? Shame on you." Nodding to her friend who drove the point home by sawing the feather's sides right in the middle of his leaking cock's tip.
"You're right, what a shamelessly horny boy" Teasing even further by reaching below for "motivation", keeping him squirming, bucking, thrusting. A single fingernail on his balls, a caustic verbal tease "coochie coochie coooo" was all it took for his body to betray him, a ticklegasm bursting all over his captor's breasts, chest and chin.
"I think this doggy needs some training".
"You're right, let's see if we can't get him to last longer by tomorrow"
