It only took a moment to decide. I'd trusted Runt not to do anything terrible to me when he transformed me. Trusting him not to do anything bad to me while we had sex seemed a lot smaller risk. Besides, I had been interested in him the moment I saw him, and Runt wasn't shy about his own lust. We might as well get it over and done with up front.
"Test drive it is." I grinned at him. "Just remember I'm human, and I doubt I can handle what you can."
He grabbed me suddenly, and I was a little afraid of what I might have gotten myself into. But he pulled me back across the bed and started sliding his hands over my body, exploring every inch of skin. I responded in kind, amazed at the smoothness and warmth. We were both getting hard, and I enjoyed the new sensations of my foreskin. As we rubbed against each other, I realized I was more sensitive than before, shivering at the pressure and pleasure. He kissed me gently, then more firmly, and we embraced tightly as mouths and tongues explored. The touching and rubbing nd hugging had me already achingly hard, but we kept it up for a long time. I was sweating and breathing hard from anticipation, but even so I was surprised when he sat up and then carefully settled on my erect cock. My eyes went wide and I gasped as he pushed down over me, his tail twisting aside. The sensations were overwhelming - not only was there more of me down there, but it was more responsive than I had ever felt.
Runt lifted up and drove down again, this time bottoming out. I arched back with a moan and started to thrust up into him, fingers gripping his forearms so tight I would probably leave bruises on him. We started to coordinate our movements, though it was not a conscious effort on my part. Runt was like an expert dance partner, moving and squeezing and pulling me along with him. The pleasure and pressure continued to build far past anything I had even imagined, and yet we continued. Runt had to have done something to make me last longer - the sex went on and on. I was just at the point where I thought I would pass out when he went rigid and I finally was able to release. Guttural grunts and gasps were all I could manage as I arched back with each powerful jet of semen, my intense pleasure seemingly mirrored by Runt. We both shuddered, him the cowboy and me the bucking bronco, until the last ejaculation emptied me and fell back on the bed. Even then I was still erect, and he continued to milk me until I finally softened and slid out.
Both the bed and I were soaked with sweat, and I could see the rivulets running down Runt's skin. It took a minute or more for me to get my pounding heart and breathing, and I stared up at Runt feeling flushed and dazed. He grinned at me and traced my cheek with one finger. "So, I take it you don't want a refund?"
