In the dimly lit gym, the white twink's eyes widen as the black trainer unzips his sweatpants, revealing a monster cock that's thick and long. The trainer, with a smirk, orders the twink to his knees. The twink hesitates, then eagerly opens his mouth, trying to take in the black cock. The trainer, not satisfied with the twink's amateur skills, grabs his head, pushing his cock deeper, making the twink gag and choke. The trainer's big black dick stretches the twink's mouth, leaving it wet and glistening as he teaches the twink the art of deepthroating.
