Ok welll now it's Saturday and last night I contined masturbating until about 1 am, so all in all it was about a 4 hour session. I used clothes pegs on my nipples for another 15 minutes and I was on my cam and chatting to a few others.
I was so horny not having cum for so long that I was getting really close to cumming several times and always managed to stop, then after a short pause begin again. I carried on this edging for ages, and then one time I was looking at the pc screen and suddenly I felt something running down my penis! I looked down and that thick creamy cum that I sometimes get before my orgasm was overflowing out of my cock and just oozing over my cock head and straight down my hard cock - I didn't even know it had started except for the great feeling that accompanies it! I wasn't even holding my cock when it started flowing! I Love these types of jack-off session when that happens, but I can never tell when it is going to happen. It only happens to me in about 20% of my really long masturbation and edging sessions, which is what I did last night! But even on those long sessions it happens quite rarely.
So after rubbing this lovely fluid into my erect penis and over my exposed cock-head, I continued edging and wanking for a while longer until I had to end it all with a huge explosion of creamy cum. That was the first time I had allowed myself to cum in almost a week and after such a lot of mastubating over the last few days it was brilliant.
