I was out of town on a construction job, to keep costs down I roomed with a another guy, he was a few years younger than me, on night after having a shower he noticed that I was uncircumcised, he asked if I had ever experienced cock docking, not ever hearing of this I said no, he explained how it was done and as he was telling me I was getting very aroused, I am also straight but would like to give it a go, I was a little bigger than he was and soon I had my foreskin covering his glans, the feeling was awesome, we both were rubbing and quite quickly we were ejaculating cum oozing out of us both, after disconnecting and cleaning up we agreed to do it again soon, it was a great new experience for me.
