Melissa screams, "Please fuck my ass, Master!"

As soon as the last word escapes her lips, you shove forward, feeling the tight sphincter part as the head of your dick disappears into her asshole. Melissa emits a blood-curdling scream as your shaft slowly slips into her, until finally, your hips press against hers as you bury your cock deep in her bowels. The slickness of the pussy-juice lube has already begun to wear off, so you call out to your assistant. He unlocks the door and enters.

"You called, Mr. Doe?"

"Yes. I believe my plaything here would appreciate some lubrication. Wouldn't you, ****?"

"Y-Y-Yes, p-p-please." Her head lies to one side, her hair limp across her face.

"I'll be right back, sir." He closes the door behind him, then returns a few seconds later with a bottle of lube. He crosses to the other side of the table, standing at Melissa's head, and hands you the lube over her back.

"Thank you, John. ****, don't you wish to thank John for his kindness?"

She looks up, and realizes with a start that John is standing naked before her, a huge erection bobbing inches from her nose. "I..."

On cue from you, John grabs the back of Melissa's head and takes the opportunity afforded by Melissa's open mouth. He pumps his hips back and forth, holding her firmly in place, as you open the bottle and squeeze out a glob of lube onto your hand. You place your fingers on either side of your dick as you slide it out of Melissa's asshole, letting the lube smear onto your shaft. You let the head pop out of her, rub the lube remaining on your palm onto your head, and ease it back in. Her squeal is muffled by John's cock, now pumping faster between her lips.

You grab ahold of her hips and pick up the pace quickly, feeling your dick swell against the tightness of her virgin asshole. You begin to feel stirrings in your balls as John throws his head back and gives one final, deep thrust down Melissa's throat. She squirms a little as John pumps his load into her stomach. He looks down and says, "You're welcome, Ma'am." She shakes her head as he uses her hair to clean off the residue from his member, then he walks out the door and re-locks it.

"Did you enjoy your little snack, whore? Ready for the main course?"

"What are you talking about?"

"Ah-ah, you forget your manners again."

"Okay, what are you talking about, Master?"

"That's better. I'm just letting you know that I'm almost ready to cum, so you can get ready for your first taste of your own shit, served with a side of semen."

"You said you wouldn't do that if I begged you!"

"Um, no, I said I would do that if you didn't beg. But I planned to do it either way. Ohhh, get ready!"

"NO!" But she has underestimated you. You grab her hair and pull her to a kneeling position, yanking hard on her hair so her mouth opens involuntarily. Her eyes widen in shock and horror as you shove your cock, slick with shit, into her open mouth. She makes gurgling, **** sounds as she tries to keep her stomach down as you pump your seed once more into her mouth. Once you're finished, you let go of her, and she half-crawls, half-runs to the washroom.
