I heard some time ago from a guy at college whose girlfriend at the time would stick her finger in his asshole when he came. He said the sensation sent him through the roof. Yesterday as I was getting a handjob (gotta love those), I asked her to stick her finger in me as I came. She had never done this before, but was game to try. I told her right when I was cumming and she stuck her finger in me. OH MY GOSH! I literally screamed from the heightened sensations. It at least doubled, and maybe tripled my orgasm. I was unable to even speak for at least a minute. Maybe more, as I lost track of time. My head was swimming. If you haven't tried this before guys, you gotta try it. Wow! Rocked my world!
