The boy's mistress, a seasoned femdom, encourages his exploration of bisexual pleasures. She orders him to stroke his hard cock while she fucks him with the dildo, enjoying the view from her slave boy's perspective. She pushes him to the edge of orgasm, then stops, denying him release as part of his training. She grinds the toy against his prostate, making him squirm and beg for more, but she maintains control, keeping him in a state of desperate, bi-curious ecstasy.
