I used to baby sit this hyper nine-year-old boy when I was in the 10th grade before getting a steady paying job at a bike shop. This boy was always asking me if I wanted to have a peeing contest.
One day I was watching him at his house when he brought up the suggestion of having a contest. I told him if he never bugged me about it again I would do it, and he agreed.
His idea of a peeing contest was that we both stand over the toilet and the person to pee the longest was the winner.
We went into his bathroom and took opposite sides of the toilet and both began peeing. I was still urinating long after he had stopped and I could tell he was staring at me. He put his hand under my urine stream. I said to him, 'Don't do that,' and he just calmly whipped his hand on his shirt.
Later that day he asks me, 'How do I get my wiener as big as yours?' I told him it would just grow. He looks at me and pulls his pants down and says, 'Like this?' showing me that he had an erection. I just laughed and pulled my six-inch, erect penis out and told him he had a few years of growing yet to do.
After that day he would mention the incident at the worst moments making me so nervous, I really regretted having the peeing contest. Yet did it again on the promise he would never mention it again. He kept his promise somewhat but always wanted me to have a peeing contest with him every time I saw him. That memory in my head has made me think about it often while using the restroom turning it into a somewhat sexual experience.
