In the dimly lit dungeon, a bound and eager trainee awaits their anal initiation. Tied securely, they're left vulnerable, their ass on display. A thick, veined cock presses against their tight hole, while another slave gags them with a meaty dick, muffling cries of pleasure and pain. The fucking is hard, relentless, as the trainee's ass is stretched to its limit. The room echoes with the sounds of flesh slapping flesh and the trainee's desperate moans.
