When I'm horny I don't want it to end. I reach a state in which only tits, ass and pussy matter to me and I just continue to jerk off and stop it when I would come in the next few seconds.
Its an unbelievable feeling.
Are you doing it? What is your record in one session?
I once did it for 25 hours. When I finally came it felt awesome. And I felt like a perv, I can tell you that.
