It left me fucking drained. As my jizz loads got smaller the contractions and therefore the orgasms got more intense. Later on the gap between hitting the point of no return and spunking stretched out to about a minute of contractions wracking my body.
I had to wank longer and longer to reach orgasm each time and I literally ran out of time. I reckon I could have banged out a 9th if I'd had more cock time but I made the mistake of doing some work in the yard. Next time I need to have a proper "lost day" and literally just wank, piss, drink beer and repeat, all day long.
I started off dry wanking and then started using vitamin e cream as lube and I was surprised my dong didn't get sore. I know it looks sore at orgasm 6 but it wasn't really. The main effect was the next day my bod felt like it had had a right battering, as if I'd been doing a massive Krav Maga session and mentally I felt quite listless. It took 3 or 4 days before I had a random hard-on and it was only yesterday I started to get horny again.
I enjoyed the motorbike wanks the most. They weren't the most intense orgasms, although the big load I got in the first was really cool, but they felt right; down n' dirty and kind of centred me, setting me up for the test of the sessions.
