In the dimly lit dungeon, a submissive male kneels, eyes downcast. His femdom mistress stands tall, her heels clicking on the stone floor. She commands, "You will learn to eat cum like a good pet." He nods, swallowing hard. She produces a tube of lube, coating his erect cock, "Jack off, slut." He hesitates, then begins to stroke, his face flushing. "Faster," she demands, "And when you cum, you'll swallow every drop." He obeys, his body tensing as he nears orgasm. His cock pulses, and he catches the streams of cum in his mouth, struggling to contain it all. She smiles cruelly, "Well done, pet. Now, let's practice again."
