Schwanzpeitschen und analspiel bis zum abspritzen

I had the craziest masturbation experience the other day. Started out just playing with my ass, a few medium-size dildos, anal beads, and so on. But I got so horny I felt I must do something drastically kinkier and sexually charged. So I started whipping my cock, first with lighter and softer implements, then heavier and more distressful. To my shock, the feeling was so intense and I was so aroused my cock started pumping out sperm while being whipped.
