Nikky Knightly, the all-American teen, is in for a surprise when her black gym trainer takes her sexual training to the next level. After a sweaty workout, he orders Nikky to her knees, his huge cock already hard and ready. Nikky, though inexperienced, is eager to please, taking the thick head into her mouth and sucking tentatively. The trainer, however, has other plans. He grips her hair, pushing her head down, facefucking her tight little mouth until tears stream down her face. Nikky gags and struggles, but the trainer is relentless, determined to teach her the art of taking a big cock.
