In a cramped, dimly lit office, the jock's bare, firm ass is on full display as the guard, towering behind him, grips his hips tightly. The guard's massive, veined cock, already slick with spit and pre-cum, presses against the jock's tiny, pink hole. With a grunt, he pushes in, stretching the twink's inexperienced ass around his thick girth. The jock gasps, pain and pleasure mingling as the guard begins a steady, punishing rhythm, his heavy balls slapping against the jock's taint. The guard's powerful muscles flex and tense, his raw, animalistic grunts filling the room as he fucks the jock raw, claiming his straight ass as his own, leaving it gaping and well-used.
