Pulled back to reality, I felt my Mistress begin to stiffen behind me. Her orgasm was very, very close. Sometimes she'll simply pull out and lay on the floor, forcing me to complete the job with my tongue and fingers. Sometimes she'll mount me and ride my stiff cock to bring her off. This time, though, she stayed inside me, pressing herself more and more urgently against my ass. When she came, she grasped heavily at me, gouging and scratching my back and sides with her long nails, even while determined to push that big cock as far up my ass as possible. Finally she pulled away, the vacancy in my body a palpable disappointment. I'd gotten what I wanted, and so had she. But I still hadn't cum yet, and my body was screaming for relief.

Rule #9: The session is only over by mutual agreement, with the Mistress having the most say. It can last as long as the Mistress determines.

Rule #10: The Mistress can refuse any requested session without explanation to the slave. The Mistress shall be accorded the opportunity to demand a session up to six times per year. These shall be denoted by a black chip, which will be handed to the slave.

I'd guess this stage is the same for both men and women, no matter what type of sex you're having. The place where one of you is perfectly sated, but the other still has something to complete. Of course, as a sex slave, I have no right to demand an orgasmic finish. And, in fact, on a few occasions my Mistress has left me to wallow in my frustration, denying me a finish either as a punishment or for her own amusement. Fortunately, this time she took pity on me. First, she directed me to grab a dinner plate from the kitchen. Seated imperiously on the couch, she first made me kneel on all fours and suck her toes, while she used a crop to whip my bare and well-fucked ass. Then I was made to kneel upright before her, while she used the same crop to smack my now throbbing nipples. Finally she let me begin to jack off, slowly dripping lubricating oil onto my hard-working hands and cock. By this time I'd been hard and soft over a dozen times since my last cumshot, assuring that I'd built up a huge reservoir of cum.

It didn't take long for me to get to the edge and inform her of it. Daintily, she put the dinner plate on the floor and placed her feet on top of it. Just moments later, I shot a huge load of cum all over her feet and on the plate, my sticky seed quickly coating her ankles, feet and toes. So explosive was my orgasm that I literally swayed back and forth, my legs threatening to give out altogether.

"Look at the mess you've made," my wife said, lightly rapping my hyper-sensitive cock head with her crop. The mere touch sent darts of pain shooting through my system. "Clean it up. Now!" The edge in her voice was a sharp as the pain she'd just delivered, and I fell to the floor to begin licking the viscous fluid from her feet, licking where I could, sucking it from her toes. As I did, I flashed a final time to my fantasy. The stranger on the edge of orgasm, fucking my wife from behind. Me beneath them, watching his big manhood pump in and out of her, stretching her pussy and teasing her clit. And me, reaching up to thumb her nipples as they sway above me, then reaching down to rub his big, hard balls in their tight sac as they prepare to coat her insides. But at some unseen signal from my wife, he pulls his thick, slick cock from her cunt and begins to jack it off. Pulling my eyes from the sight of the angry slit disappearing again and again inside his meaty hand, I tilt my head back to see my wife watching us lustfully, anticipating this cumshot as much as the man about to provide it. I shift my gaze back to his cock just in time to see the first spurt fly toward my face. Reflexively I close my eyes as the hot liquid splashes on my nose, cheeks and lips. When the second spurt only reaches my chin, I open my eyes to witness the rest of it splattering onto me, seemingly by the gallon, dripping into my chest hair, glops of it slowly sliding on my skin. As he squeezes the final drops onto my stomach, my wife sidles backward until her cunt is positioned over the largest pool of cum on my chest. She then sits down on me, squirming from side to side to transfer his semen onto her body. Then, inching forward, I'm forced to lick his cum off my wife's legs, thighs and pussy. With all the cum that I can still feel on my body, I know that the night's not going to end until I've cleaned both of them of his hot, salty, viscous cum. And that my wife's surely going to schedule another rendezvous with this well-hung man, so she can enjoy his big, thick dick one more time.

That's what I imagined as I sucked my cum from her feet. And as she pulled her feet from beneath me and pressed my head down into the cum puddled on the dinner plate. The taste of it didn't matter, nor the depravity of it. I knew that I was already auditioning for the next session. And though the urgent need to be dominated had fled from my body with the onrush of cum, I knew that it would return again. It always does.

The End.
