i was on my way to football training and my friends mum used to take us but my friend hurt his foot so it was just me and his mum in the people carrier. i was in the second row and had a boner so just went for it. She had the radio on so i dont think she heard. When i was just about to blow i looked for something in my bag to use but couldnt find anything in time so just had to use my hand. I jumped out the car and quickly washed it off when i got into the toilets.
