In a kinky twist on traditional education, a bi-curious man finds himself in a Femdom's dungeon, eager to learn the ropes of BDSM. She straps on a massive, realistic cock and orders him to his knees, demanding he prove his bisexual prowess by servicing her. He gulps down her silicone length, gagging and choking as she fucks his face, his own cock leaking in his pants. She teases him, bringing him close to the edge before backing off, keeping him in a state of constant, frustrated arousal. The lesson ends with him begging for mercy, his face covered in spit and pre-cum, ready for whatever twisted lesson comes next.
