Night after night, in that colourless cell, that's exactly what she did.
Her bottom was a large and tireless muscle, covered by a soft, feminine layer that pressed down hard on my screaming airways (as she soon took to sitting on my face). Even with all the agony it caused, it needed worship. I revered it.
I rose, every morning, exhausted and bruised, my arsehole raw and throbbing, my bottom covered in welts, and in spite of it all, I'd lie for what felt like hours, eying my abusive lover in a trance. I stared at her powerful hips and recalled, vividly, their repetitive movements the night before. That horizontal forward-and-back, merciless thrusting. My hands, in answer, gripping thin beige sheets with all their strength. My knees, grazed from her religiously-performed post-lunch concrete-floor-violation of my weary hole, rising off the mattress, such was the animalistic strength with which she slammed away. Her arms tense, fingers scraping my scalp, using fistfuls of my hair to lever her relentless pounding.
My pleas for her to 'slow down' and 'go easy' were always met with barbaric indifference (although, to tell the truth, they were hardly uttered after one month of our co-habitation). And it was this; the reduction of my complaints, that brought it on. What Coco found even more appealing than my hungry bottom were my screams of agony. And they still happened! Albeit not as loudly. Coco's steel-cock, I cannot emphasise enough, was enormous and I don't think any normal person could ever get completely used to it, especially given the way she wielded it. But, nevertheless, I began I look forward to my daily hole-wreaking, and this most certainly did not sit well with my lover.
We had shared a cell for nearly two months and it had been a most bizarre evening because, for the first time, I went to bed with my ass unpunished. I even went so far as to drop my towel on the floor, in front of her, and bend over, tempting my goddess. The blatant gesture was, however, ignored entirely. I made my displeasure known by jerking off in the top bunk noisily, immediately after she'd switched off her light. It was a bold move and I knew if it had succeeded in stirring her, I'd most likely regret it. But yet again it was met with silence and inaction. Having climaxed and made a sufficient mess of myself, I drifted off to sleep.
The prison was still quiet and the sky dark when the light came on and I found myself unable to move my arms. They had been tied, I deduced immediately. I heard an unfamiliar, deep, female voice echo through the cell, and then another.
'Well, I'll tell you what I think once I've tried him out.' Said the first.
'Just don't stretch him out too much,' laughed the second.
I wiggled myself over to face the intruders.
Coco was sitting on the stool near the sink, a rapidly growing cock in her hand, wearing her trademark evil grin. The two ladies stood next to her. They were impossibly tall, with long, lean muscles and dark skin; darker than Coco's. Their cocks hung heavy and half-way to their knees. They were identical. Twins.
