Bound and helpless, the bisexual slave boy is tormented by his Mistress's skilled use of a realistic dildo. She teases his lips, his tongue, his throat, making him gag and drool. His eyes water, but he's trained to take it, to crave it. She humiliates him, calling him a pathetic little bisexual slut, making him fantasize about sucking cock while pleasing her. His body responds, cock straining against his restraints, as she fucks his face, pushing the toy deep until he gags. She pulls back, laughing, and orders him to clean the toy, leaving him panting and desperate for more.
