The combination of discomfort and pleasure is quite mind blowing. My ass was hurting because I sat in that position for over an hour. (put the rope on takes a while if you're not a pro) Obviously couldn't stretch my legs and I personally always masturbate and cum with my legs stretched and toes pointed. Couldn't do it here. So my pussy was vibrating, which was such a nice sensation but with the ball gag in my mouth I was trying not to drown on my own spit. Eventually the orgasm wasn't as much about pleasure but about release. It meant that I was free. I could be untied, I could stretch my legs soon and I wouldn't have to control whatever was going on in my mouth anymore.
