I was 14 at the time and walking my girlfriend Caroline home from school when she complained that she was desperate for the toilet. I told her to go in the bushes but she said she couldn't do that as it was a number two and she'd rather do that in the toilet. I got really turned on knowing Caroline was desperate for a poo and I got a hard on. We kept walking for a while and Caroline stopped suddenly. Her face was red as a beetroot and she moved her feet apart and bent her knees a little bit. The smell of poo filled the air around her and Caroline said she was sorry but she just had to go so bad. I got so excited I came in my pants and I told her not to worry about it because she'd just made me cum.
