Muscled Straight Jock's Anal Awakening
A strapping, straight jock finds himself in an unexpected situation when his doctor, an experienced gay man, offers to help with a "muscle strain" in his lower back. The jock, hesitant but horny, agrees. The doctor, a silver fox with a six-pack, starts massaging the jock's body, his hands lingering on the athlete's firm ass and thick, circumcised cock. The jock, initially tense, starts to relax, his cock twitching as the doc's hand brushes against it. The doc, noticing the jock's growing erection, takes it as a sign to proceed. He lubes up and inserts a finger into the jock's virgin ass, making the straight boy gasp. The doc then replaces his finger with his own cut cock, slowly pushing in as the jock tenses up, then moans in pleasure as he feels the doc's cock fill him up.
