In the dimly lit gym, the trainer, a tall, muscular man, watches his client's lithe form as he stretches. The client, a twink with a tight body and innocent eyes, is oblivious to the trainer's growing desire. As they move through the workout, the trainer's hands linger on the client's skin, feeling the heat between them. When the client bends over to touch his toes, the trainer can't resist. He pulls out his throbbing cock, rubbing it against the client's ass. The client, shocked but aroused, looks back, and the trainer seizes the moment, pushing his cock inside, starting a rough, intense fuck that leaves them both panting and spent.
