This one time at my buddy Dane's house, we were blazed as shit, and I was just sitting there listening to music. After a couple of minutes of zoning out, I felt that feeling you get when you're tickled running down my body in waves. Then I felt colors hitting me like ocean waves. THEN I felt like something was zooming into my whole body, and when it did I had a FULL-BODY ORGASM! I only held it for a second to avoid creaming my jeans in front of Dane and his retarded friend, though.
