Deny Her

You keep the vibrator pressed into her pussy, targeting her clit. Her moans and begging become more furtive as she approaches her climax.

But you snatch the wand away, making her rising moans collapse into whimpers. "What was that, bitch? Do you want to cum?" you ask but walk away as she responds.

Her pathetic begging gets more and more desperate as she hears your footsteps get farther away. A part of you wants to return and see just what she'll do to cum, but the thought of leaving her so hopelessly on the edge of release is just too good. So you return the vibrating wand and leave, the sex slave's pleading still in your ears.
