Plunger
Hey, I was at a doctor's office today and had to go to the bathroom. When I was there, they had a plunger and the top had bumps. So I thought to myself that I could masturbate and stick it up my butt. As I got more horney, my butt opened up. When I first stuck it in there it hurt a little bit, but then the pain went away and began pleasure. I used my left hand to shove it into my hand and my right hand to jerk off. Go buy one of these plungers if you love things in your butt to achieve a huge orgasm.
