Never happened to me, but I was in the book store one day and I had to take a shit. So I'm in the bathroom doing my business and I hear rough breathing in the stall next to me. I'm thinking "maybe this guy just needs some laxatives" so I go on with my business and I start to hear other noises, sounded like pages turning and then he hit warp speed....all I could hear was fap, fap, fap, fap, fap, fap, I could tell by the sound he was wearing windbreaker pants. By this time I knew this guy was jerking off and I had one of those two foot long terds going so I was kinda stuck for a few minutes. Then this sick bastard starts moaning, not loud but he was. So I finished up and got the fuck out of there, but curiosity got the best of me so I got my book and sat in the chair closest to the restrooms and waited to see who is was beating his meat next to me. Shure enough some fat ass walks out with wind breaker pants and a sweater on. A short while after that I went to a friends house and explained what happened earlier. He replies "oh yea everytime I'm there I jerk off, if you open the baby changing station there are always a couple of porno mags in there, but I'm not courteous to the next guy I just bust my nut in the pages and put it back."
