Looking out my upstairs window and seeing the next door boys playing in their backyard today reminded me of when I did things like that. It was a warm day and they were playing on a slip and slide. The parents were out there with them and their boys were doing it naked. They were trying to get their parents to try it too but they kept saying no until their father finally gave in. He began to undress and I wondered if would do it naked too but he kept his underwear on. After sliding a few times he might as well have gone naked because when his white cotton undies got wet they became very sheer. I think he might have realized this too and just took them off. I was surprised he was outside so exposed. I decided to go outside and they immediately saw me. They said hello but the father didn't seem to care I was seeing him naked. I was thinking how cool it would be to join them but didn't think it would happen. The father however did say he would invite me over but they were almost done and had to get going. They began to towel off and I decided to show them I had no problem being nude and them seeing me. I kicked off the shoes I wearing along with the shorts and undies I was wearing. I lay face down on my lounge chair to get some sun but made sure they saw all of me before I did. The father said next time they pulled out the slip and slide they will make sure to invite me over. The mother said she would make I get invited too.
