In the dimly lit dungeon, a femdom forum regular, MistressV, begins her CBT session. She straddles her slave, his balls pressed against her leather-clad crotch. She grinds, her cruel smile widening as he squirms. "Today, you learn the meaning of my love," she purrs, producing a ball-stretcher and a metal cock ring.

She smirks, "Now, my pet, let's make some beautiful, agonizing music together."
