A bi-sexual sub's deepest fantasies are explored and exploited in this humiliating domination session. Strapped to a chair, they're forced to service their mistress's strap-on and a real cock, back and forth, until they're gagging and drooling. The mistress, a stern Femdom, torments them with degrading talk, pushing their limits, making them face their bisexual desires, and leaving them begging for more.
