In a dimly lit room, a sissy, clad in lacy panties and a tight corset, is introduced to the world of BDSM and bisexual pleasure. His mistress, a stern dominatrix, presents him with two cocks - her own strap-on and a real, throbbing member. The sissy's eyes widen, but he's eager to please. He starts with the mistress' toy, taking it into his mouth, his cheeks hollowing as he sucks. The real cock, however, intimidates him. It's thick, veiny, and pulsating with desire. The mistress pushes his head down, forcing him to take it all, her hand gripping his hair tightly. The sissy gags, but the mistress just smiles, enjoying the sight of her sissy learning to serve both cocks.
