The result was astonishing! She grunted and thrust her arse backwards. Her hole, which had been tense, had relaxed so quickly it was as though the hole was actually sucking my cock into it. My body jerked forward as the knob end of my cock accepted the involuntary invitation and disappeared inside her. She gave a small cry, but not too loudly and although the sphincter tightened painfully round my cock, the tender end was now inside and I was able to hold position.
It is a biological impossibility to strain continuously, and she was able to relax for a second.. That was what I was waiting for. I thrusting my hips forward, the full length of my cock parted the folds of her back passage until my groin slapped into her arse cheeks. I gripped her thighs with both hands and held tightly onto them, so no matter how much she tensed up, my cock stayed rammed all the way inside her.
She was sweating by now but I felt the hole relax ever so slightly, so I reckoned I could get on with giving her arse a good fucking.
The heat from her back passage was far, far hotter than any cunt I’d ever been in. This, combined with the natural tightness of her virginal hole was driving me mad with the need to fuck, fuck, fuck as hard and fast as I could, but I controlled myself. Pulling my cock just far enough out to leave my cock-end inside I pushed forward again. Keeping the movement reasonably slow, I was enjoying the feeling of those hot, pulsing folds of inner flesh squeezing, inch by inch, along the invading length of my shaft. As each slow thrust completed its inwards push, my balls slapped against her arse cheeks, and she gave a slight moan, and bucked backwards against me.
By now, I was so aroused, I couldn’t hold that slow and gentle rhythm much longer. Quicker and quicker I plunged into her, she was keeping speed with me, humping backwards in time with my thrusting. Her legs trembled against mine and I sensed she was coming to an orgasm. I couldn’t last any longer. The end of my cock was now in that extremely painful state just before cumming. One last thrust and as I went on to my toes my cock felt it was exploding as I shot my load deep inside her back passage. I was barely conscious of her howling into her head covering, but there was no doubt she had experienced her first anal controlled orgasm. So that was one thing we had in common!
As my cum forced its way out and into her channel, I moved very slightly, and felt the juices in her gut mixing with my cum so that I could feel the first inches of my cock moving easily with the new slipperiness that was coating her inner tunnel. The tenderness of my exposed glans was stinging with the pressure of her inner walls and the wetness we were both producing. I moved ever so slightly backwards to relieve my foreskin.
Totally exhausted, I stayed fully inside her, as we both breathed heavily. The sensation of her arse cheeks being squashed against my crotch, although no different from cunt fucking a woman doggy-style, was heightened by the heat of her back passage enclosing my shaft and the extra tightness of the anal ring clamped around the root of my cock. I pulled suddenly out of her, but as my cock end came free, she jerked and gasped at the unexpected emptiness, then took her hands off the bed rail, reached backwards and actually took hold of the sides of my thighs.
