A college student, eager to gain mass, signs up for personal training sessions with a renowned, ruggedly handsome instructor. Their workouts grow increasingly intimate, with the trainer's strong hands guiding the student through exercises that seem to have more to do with pleasure than pain. One day, as the student's ass grinds against the trainer's crotch during a set, the trainer can't help but grow hard. The student feels it, and their eyes meet, filled with unspoken desire. The trainer, his voice a low growl, asks, "You want to know what it's like to be fucked by a real man?" The student, breathless with anticipation, eagerly nods, and the trainer proceeds to spank, tease, and ravage the student's tight, young body, giving him a lesson he'll never forget.
