Keep me on my knees

“On your knees, back against the wall.” The leash tugs, and I demand my shaking limbs cooperate so that I can obey. Moving is awful, driving overwhelming sensation into overstimulation, and I find tears leaking from my eyes as I position myself as ordered. Your cool hand caresses my hot cheek.

“Good boy. You’re doing so good for me.” My shoulders shake with a suppressed sob as the train bumps and a fresh wave of overstimulation hits me.

“Thank you, Sir,” I mouth. You reach down and clip my ankle cuffs to the floor-level bar. The chain dangles, just barely above the floor.

“Arms out.” I spread my arms and you clip first one wrist cuff, then the other, to the conveniently waist-height rail. Then you clip my collar to it as well. “Keep your head up, boy. I want to watch your face.” The vibration level in my cunt increases, and my chest bucks and heaves as I bite down on my lips. Then it drops down again, and I collapse against my bonds, gasping.

“I’ve wondered for a while, how many orgasms I can get out of you between work and home? Not that this is a fair test, I’d want to start as soon as we boarded the train. Still, it could be a useful comparison.” You grin, sharp and not at all nice. I gape at you.

“Sir- Sir please-” You hook the toe of your shoe in the chain and tug. My head snaps back on my neck as I strangle my screech down to a hysterical whimper.

“If you don’t make at least three, I’m going to be disappointed in you. You have… Twelve minutes.” The vibration increases the smallest amount the remote allows. You push the chain back and forth, gently this time. You know me, know my body, what will send me over the edge and what will send me flying irrecoverably beyond. Your hand considerately muffles my howl as you propel me into my first orgasm. When you take it away, I’m panting desperately. It’s too much, the chain is too much, my cunt is too full, the goddamned vibrations are too fucking much.

“Please, I can’t.”

“I know you can. Do it for me. You don’t even have to be quiet this time.” You’re toying with the chain again, and I let out a full-throated sob.

By the time we reach our stop, we’ve gathered a small crowd of very interested onlookers, my throat has gone hoarse, and you’ve dragged four orgasms from my poor overstimulated body. When you undo the restraints, I can’t walk, so you half-carry me home. You kiss my temple. “Good boy. I told you you could do it. I can’t wait to see how many you can give me over the whole trip.”
