The mistress toldthe class what they now would experience the loss of control and it could bevery dangerous to do such a thing with a customer they di... not know. She wentbehind them and out of sight she suddenly pulled a leather hood over their headand also shovelled a gag ball in their mouth. The hood had built-in speakersand through them she informed them that they now would test the concept of paina pleasure on them. Totally enclosedin darkness, they waited in a tense state for what to. The tension builds, I let go of myself only momentarily as I wait for those familiar sensations to subside just a bit. I marvel at how my cock mimics my heartbeat, my pulse if you will. I close my eyes, and I see you, standing naked before me. I once again take hold of my still rigid cock. I imagine it is you taking hold of it. The grip it tightens as it begins once again gliding up and down my shaft. The motions start out slowly but steadily they increase in speed. God, how I wish it were. I let my hands slide up under the tank top to get a nice warm skin to skin feel of those marvelous titties. Not too big, not too small…perfect! As I was enjoying myself with those pointy nipples, I felt her undo my belt and pants. They fell to the floor and I stood there in only my briefs. They were straining to contain my rock hard erection. She reached in and freed my pleading penis and pushed my briefs to the floor. She paused long enough to pull her top over her head. There I stood, facing. Suddenly a waterfall occurs. Both women’s words tumble from them in a cascading manner. Not so much about their final projects but concern about what them finishing their degrees will mean.Emma calms them enough, while Donald's mind is whirling with what is being said and not said about this all. But finally, it all becomes clearer.Both Julie’s and Karen’s theses are more or less finished, they gush with thanks for the data Donald provided from the institute and Emma’s clear head suggestions.
