In a bustling gay sex shop, a fit, straight trainer, new to the scene, is propositioned by a horny patron. The trainer, intrigued by the taboo and the promise of cash, agrees to a public blowjob. The patron, a muscular, experienced gay hunk, leads him to a secluded corner. The trainer, nervous but excited, strips down to his boxers, revealing his toned body. The patron eagerly takes out his throbbing cock, feeding it to the trainer who tentatively sucks, learning the ropes. The trainer's inexperience turns the patron on, and he fucks the trainer's mouth, making him gag and drool. The trainer, now more comfortable, gives a decent blowjob, getting the patron close. The patron pulls out, jerking off onto the trainer's face, marking him with his hot cum.
