I love masturbating in public. Like the OP, my orgasms are over the top when I'm being watched. One of my favorite activities is driving around with my sunroof open, wearing a short skirt with no panties and my breasts out in full view. I play with my tits while the truckers watch, and if one paces me for a while I'll start playing with my pussy for them. Makes me so wet knowing that they're getting hard and probably stroking themselves as they watch me and I orgasm hard and fast.
