Had the strangest thing happen, dunno if I could make it happen. I visited a chick this weekend. We were having sex all day friday and saturday. So as you can imagine it was hard for me to cum. It was saturday evening when this happened. We were fucking, and she gets sore and starts giving me a HJ. After a little bit, I started to climax. I kept climaxing and hitting it that point but not actually orgasming or cumming. I was touching that spot of no return but I was coming back down. I couldn't cum at all. It felt fucking amazing, but I don't know what the hell happened. What is this called? Can it be done on command / controlled?
