I must have been doing a good job because all of a sudden he put his hands on my head and held me in place while he shot load after load of hot cum in...my mouth. It didn't taste bad at all and I just swallowed as fast as I could until he had drained his ball inside of me. He held my mouth over his cock until it began to soften and gradually it slipped out. He told me that I learned quickly and if I wanted to repeat that enjoyment to come back any Tue or Thursday and he would let me swim for. He said he would love if I did help.I replied jokingly as I was getting into the shower that it seems he has it all handle and I'll just watch as he jerks off. He then asked please could I jerk him off and I replied saying only if you wash my back afterwards. Which he agreed to.I moved to stand behind him and placed my hand over his hard cock and started jerking him off. My other hand was on his handsome chest. He placed his arms backwards and on my body as I jerked his cock off. He was taking. It was beautiful I kept pushing back against him to get more and more in I felt so full and I was continually cumming, pre cum was almost pouring from my cock swaying beneath me.Then, as he grunted in my ear, he really started to speed up, ramming into me hard, that was it for me, I started to cum, spurt after spurt over his bed as he fucked me, it was sensational!! Moments later he came, so hard in me I could feel his cum warm and pulsing into the condom, I collapsed onto the bed as I came. That worked well and the next thing, with a loud grunt from Nathan, half my dick was inside him. I stopped for a moment as he got used to the feeling then very slowly began to rock back and forth. With each forward push I was getting inside him further until Nathan began to hump back onto my cock harder and harder. Now I was fucking him quite hard and before long Nathan began panting and loudly saying “Fuck me, FUCK ME… MORE.”Meanwhile, Jim had climbed out from beneath Nathan and was now lubing.
