Oh my gooood.

Gemma slides her cum covered feet back into her high heels and stands up from the couch, towering over the top of your quivering form. She raises one of her feet and begins dragging the pointed stiletto heel up the underside of your cock and all over your sensitive slit. You wince in pain and pleasure as she pokes at your glans with the heel, before she presses down with her toe on your scrotum, applying pressure to your aching balls. You cry out in incomprehensible pain and ecstasy, as the intensity of the **** she's applying on your sensitive organs is amplified by the throes of post-orgasm pleasure still circulating through your body. Your arms and legs begin to flail uncontrollably, as she again manages to have complete command of your body using only your testicles.

"Did you enjoy yourself?" she asks, twisting her toes on your balls like she's stamping out a cigarette.

"Y-yes Gemma!" you yelp, tears beginning to well up in the corners of your eyes.

"No, no, no..." she scolds, leaning forward with her foot still on your balls and slapping the tip of your cock with the back of her hand, "You'll call me Mistress from now on."

You nod frantically, unable to speak as a lump forms in your throat, powerless to do anything against her. It feels like an eternity before he steps off your balls and walks out of the office, leaving you there on the couch with your pants down covered in your own cum.
