I am going to make you make me pregnant, Slave.
Run my labia along your cock so lightly, until you can't breathe from desperation.
Did I give you permission to cum? Or is your good behavior just going to be overwhelmed by your desire?
It's okay. Let it out. I'm the one who created that need in you.
I'll start by pushing you back on the bed, grinning like a hungry, mad woman. I want your seed in me so badly, but I want to make you suffer first. Let's scoot up; now I can push you back, hand on your naked chest. Settle my legs in between yours, kneeling over my prey, grinning down at you. Seeing you beneath me always makes me smile. Stretch my back from side to side like a relaxed cat, cracking my vertebrae to enjoy my comfort and your focused anticipation.
Suddenly, I pounce. My hands grab your hips, palms on your iliac crests, weight pinning you. Knowing you'll jump from the surprise, I turn my elbows out, keeping your thighs from coming up around me. Do you like that little jolt of pain from slamming your muscles into my pointy bones? Does your masochistic ass even register it?
You're too busy focusing on the nearness of my mouth to your cock. You can feel my breath, now a cool pressure as I purse my lips, next a warm envelope as I open my mouth and breathe out deeply. Enjoying your trembling, I pull back my lips and bare my teeth, making a small rasping sound bordering on a growl. Looking up, I lock eyes with you, grinning ferally. You return a look of fear and excitement, everything I crave written on your cute face.
Another few breaths, eyes locked, savoring your full attention, your fearful anticipation. Slowly, never losing eye contact, I lower my head and slide my tongue out. The tip of my tongue makes contact with the base of your shaft, and I feel your cock twitch as I watch a shiver pass through your entire body. Quivering, your breath catches in your throat while you feel the tip of my tongue run up your shaft, light as a feather.
The light touches always get you, and soon I have you writhing under my hands, holding your hips down with my bodyweight as my tongue tickles and strokes every inch of skin - your shaft, your head, your balls, your pubis. Maybe I should shove your legs up, lift you just a little, and slide my tongue down your taint and stick it in your ass. Or are you a dirty boy? Make sure you stay clean for your Mistress.
But no, that's not the direction we're going right now. I want your cum in me. I want to make you spill your seed into me and do your service as a breeding stud. And don't you dare think you have an active role in this. That'd be bull. No, I want you helpless beneath me while I bend down and shuffle my knees back, propping my weight on your hips so that I can extend the range of my mouth up your stomach and to your sides. Meanwhile, my breasts dangle down, knocking against your erect cock as lightly as they can, for udder-like endowments. I treat your belly and sides like newfound skin, kissing, sucking, licking, and nibbling my way across and ever upward. Perhaps I should mandate that you stay shaved or waxed for me... no, I'll take the occasional soft hair over your constant itchiness and any brillo pad texture.
Reaching your chest properly, I have to take my hands off your hips to support myself higher up. To keep you trapped, I press my hips down on your crotch - and then I rethink: I have a better place than my stomach for your dick to press against. Posting up in a plank position, I reach down with one hand and fondle your member, then spread and settle my legs a little, pulling your cock up to trap it between my thighs, just shy of my mons. You don't get to feel those lips just yet, and I still haven't kissed as much of you as I need to.
Thighs pulling and pressing against your cock, I roll my hips just a little, agitating your trapped manhood. Which do you enjoy more? The softness of my fat, or the hardness of my muscles? Take your pick, Slave; I can't stop you from enjoying both. And why would I want to?
