In a gay-straight experiment gone wrong, a curious straight guy agrees to bottom for the first time with a hung gay twink. The twink, excited at the prospect of popping a straight guy's cherry, lubes up his throbbing cock and pushes it into the straight guy's tight, virgin ass. The straight guy grimaces, feeling the intense pressure and discomfort, but the twink is gentle, taking his time to let the straight guy get used to the feeling of a cock in his ass. Soon, the straight guy is moaning, enjoying the sensation of getting fucked, his own cock rock hard. The twink fucks him harder, faster, the straight guy's moans growing louder, more desperate. Finally, with a grunt, the twink pulls out and cums all over the straight guy's ass, leaving him panting and satisfied, but confused about his newfound gay feelings.
