November 25th - Second Time, LONG VERSION Struggling for an orgasm for 30 minutes! Read Description!

So this was really strange and I am not sure if I have ever experienced something like that before, except maybe when I was on anti-depressants. During this session it felt like I had missed my orgasm two times! You can see pretty well when those times are once around 13 minutes, I jerk it really fiercely and soon after it goes softer again. My right arm couldn't go on any more even, nearly cramping up and then I was just not close anymore. Then it was like I had to start from the beginning. But I didn't want to give up! Then again around minute 23, I get really hard again, jerk it really fast and heavy just for it going soft a bit later again, my arm did cramp up again as well! Then I realized it wasn't working out like that, got my phone real quick and used some hentai on my phone to cum to. And then it finally worked! Worked up a pretty big spurt too in all that time, haha.
