In my fantasy, I'm licking the balls of the man who will soon fuck my wife. His balls are big and full, about the size of immature plums. They dangle from his body in a stiff sack, which barely gives way as I run my tongue up and down the skin. I suckle at each testicle, reverently kissing the source of his jism, the powerful semen that will soon coat the inside of my wife's deepest crevice. My Mistress wants his cum to be as hot as possible. As I slurp and lick at his cock and balls, I imagine what kind of Master he would be. Would he be fair and giving, allowing me my pleasure after I've given him his? Or would he be cruel and demanding, binding me to the furniture and fucking my ass repeatedly? Would he make me his personal slave, or share me with his friends, reducing me to a tight hole for the horniest of them? The thought of both scenarios excites me, and I redouble my efforts to get him ready.

Finally my wife reclines on the bed, her legs spread and her pussy eagerly awaiting his fully engorged sword. At her direction he positions himself over her, holding his cock just inches from her hot, wet pussy. I slide my hand between them, grasping his staff, and he lowers himself slightly so I can rub the massive head up and down my wife's trembling slit. Finally I position him at the entrance to her tight cunt. He waits only until my hand is clear before lowering his cock straight down into her cunt, until their bodies are flat together. She moans contentedly, her hole filled with more cock than she's ever had, save for the bigger dildos we've played with in the past. This cock, though, has a determined owner, and two balls filled with heavy semen ready to explode inside her. He's not wearing a rubber, nor does he need to. The magazine ad and screening process assured that we were all free from disease, all diseases. So we can all fuck, and be fucked, without any fear. I watch with wonder as his massive tool slides in and out of my wife's pussy. She's already raised her legs far into the air to get as much of his rod inside her as possible. The lips of her pussy pucker in and out as he goes at her, as if her cunt is stretched to the limit. She has a dazed look of ecstasy on her face, and she exhorts him to fuck her harder, harder, harder, her grin widening as he complies.

Finally he stiffens, and I know he's hosing her insides with his seed, spurt after spurt splashing against her cunt walls. He pulls out then, and I look to my Mistress for instructions. Him? Or her? She gestures to her cunt and I slide my face between her legs. The scent of his cum and her juices is heady and overwhelming. Without waiting for a prompt I shoot my tongue into her hole. Her cunt is so full the cum seeps back out around my tongue. I lap it up eagerly. I'm eating another man's cum from my wife's cunt! It tastes the same as mine. But there's so much of it! With balls that big, he must've shot a gallon into her.

I've cleaned her out in a couple minutes, and then turn back to him. He's watched the whole thing from a seat nearby. His cock is nearly flaccid, though he hasn't wiped the excess jism from the shaft. My Mistress told him that's my job. I kneel before him, playing the part of the submissive slave. I take his cock back into my mouth and suck off the mixture of juices and cum. I'm willing to serve both of them, in any way necessary.

My Mistress pushed me away, this time looking satisfied with the job I've done. "Get me Number Two," she orders, unstrapping the current strap-on from her waist. I fell over myself to get it to her. With luck, this means she will give me what I want, and get something for herself in the process.

Rule #8: The slave shall allow himself to be fucked in the ass with the tool of the Mistress' choice, to show that he is nothing more than a bitch, an animal to be used and abused for another's pleasure.

You see, in the beginning I sold this aspect to Lynn as a kind of punishment. Punish me. Fuck me. Quickly, though, she figured out that it wasn't a punishment for me. It was what I wanted. It was my reward. So the session expanded into my earning the reward, and her deciding whether I've done enough to get it. Believe me, there are many sessions that don't end up with me getting fucked. Or sessions in which she gives it to me by another means, such as a vibrator or vegetable. But the ones that do end that way are the ones that keep me coming back for more.

It's not just the feeling of it that obsesses me. It's the whole idea of it. Me, bent over, on my hands and knees, with my wife behind me, fucking me with a thick cock. Or me on my back, with my legs canted up, watching my wife slam her hard cock into me, exhibiting her ultimate power over me. Using me. Showing me who is in charge. Proving that she has the balls to bend me to her will. And me, staring up at her, watching the power fill her face. Seeing the breasts that I have teased now waving over me. Seeing the cunt that I have pounded now pounding into me. I'm fully at her mercy at that point. She holds my manhood in the palm of her hand. Or, more accurately, at the point of her cock.

Roughly, my Mistress pushed me over the arm of the couch, flipping up the skirt. Now I virtually felt like a schoolgirl, chastised and vulnerable, trembling as she awaited penetration from her boyfriend. Or her teacher. Or her drug dealer. My Mistress took the blunt end of the cock and ran it up and down my crack, teasing me with its implied power. She'd applied a little oil; the cool wetness left me feeling even more exposed. Suddenly it was at the hole to my anus, pressing against the muscles, insistently demanding entrance. I strove to relax, rewarded with the feeling of the head pressing inside, followed by mile after mile of the hard, thick shaft. She had me pinned then, her bitch, her fuck toy, spearing my ass with her powerful, powerful tool. I had sacrificed everything to be here: my control, my manhood, my dignity, my body. All to be used like this. I felt a great release, more powerful than an orgasm. For a short time, I had been relieved of all responsibilities. I could simply bend over and be taken.

Grasping my hips in her strong hands, she fucked my ass with abandon. Her cock slammed deep into me, despoiling every inch of me. No longer was it an inanimate object. Now it was her cock, her rod, as hungry and powerful as any man's. And it wanted to subjugate me, to spit its seed inside my ass, as surely as the man in our fantasy would ultimately take me and use me. All for my Mistress' pleasure.

We didn't initially use such a thick and hefty dildo, of course. Penetration was my desire, not permanent damage. At first, my Mistress fucked me with her fingers, getting my ass used to the infiltration. Then we graduated to the handles of certain kitchen utensils, gradually increasing the thickness. Finally I was at the point where I could handle more (so to speak), and then we purchased the first dildo. But there's no limit to what she can put inside me. She's fucked me with carrots and cucumbers, gourds and screwdrivers. The more humiliating the object, the better it is. Sometimes she'll take me into my workroom, tie my hands to the rafters, and violate my ass with all manner of tools and objects, recording each successful insertion with our digital camera. At other times, she'll put a vibrator inside me, just as a means to torture me with the sensations.

This time, though, there was nothing subtle about it. She fucked my ass with strong and sure strokes, as confident in her domination of me as any person could be.

Unbidden, I begged and whispered for more, "Oh, yes, Mistress. Please fuck me. Please fuck your little whore. Make me your bitch. Make me your fucking bitch. Fuck your whore. Fuck my tight ass. Make me be nasty for you."

She responded by speeding up, slamming her hips against my ass again and again. I could tell that the nub on the inside of the harness was hitting her clit just right, by the way she bent over me and drove home her big cock. My own cock was stiff beneath us, though I just couldn't get it to rub on the couch for a little relief. Sometimes she'll fuck me and give me a hand job at the same time. There's nothing to compare with the feel of shooting your load with your Mistress' hard cock shoved up your ass. Instead, I let my mind wander to our fantasy, imagining that our big dicked stranger was laying on the couch below me, and I was mouth-fucking his cock as my wife sodomized me. I could almost feel his flesh quivering in my mouth, the blood pounding, the cock stiffening. I could only watch, helpless to stop it, as he rolled away from me and positioned himself behind her, his resuscitated cock swaying at the entrance to her pussy. And my Mistress, pushing me onto my back, moving up to straddle my face, so that I'd have a worm's-eye view of his thick stick pressing inside her waiting hole. I'm mesmerized by the sight of his wet, purple head penetrating her pussy lips, stretching the skin, finding a home inside her. Soon he begins to fuck her in earnest, and my face is quickly splattered with flecks of liquid, her red-hot juices mixed with his copious semen. It's as if I'm being blessed by the product of their passion, and I open my mouth wide to take it all in.
