In a dimly lit, leather-clad dungeon, a bisexual trainer awaits her newest challenge - a self-proclaimed straight man eager to explore his hidden desires under the guise of 'training.' As he's securely bound, the trainer slips on a thick, black strapon, her own pussy throbbing at the sight of her sub's vulnerable, virgin ass. She teases him, running the head of the strapon along his crack, making him squirm and whimper. As she begins to push inside, she whispers filthy bisexual fantasies into his ear, driving him wild with lust and shame as she fucks him slowly, deeply, until he's begging for more, his own cock leaking pre-cum in testament to his enjoyment of this bisexual taboo.
