When I was in the seventh grade, I met a boy in one of my classes and we quickly became friends. We had the same likes in music, movies, TV shows, etc. It was almost like we were separated at birth.
One day when we were off from school, we had made plans to hang out at his house, which excited me because I had never been there before. Late that morning, I rode my bike over to his house, rang the doorbell and told me to come in. When I walked in, I saw that he was laying on the couch, completely naked. I asked him 'Uh, what are you doing? Why aren't you wearing anything?' 'I'm always naked at home, it's how I was raised.' His parents were divorced when he was young and he lived with his mother full time. She didn't want him having any problems with nudity when he got older, so she basically raised him as a nudist at home.
I sat down in one of the chairs and we watched TV for a few minutes. He then said 'you know, you don't have to wear all of that if you don't want to.' It was kind of hot in the house, so I took off my shirt and socks, leaving me in just my jeans and underwear. He looked at me, laughed and said 'oh come on, you can do better than that.' I probably turned five shades of red since no one had seen me naked since I was a baby, but I pulled off my pants and slowly peeled off my underwear, sitting back down quickly and tucking my penis between my legs.
'Feel better now?' 'A little, yeah.' Actually, it felt amazing being naked with someone else. Seeing him being so free about it, laying there spread out and walking around, I became more relaxed as well, not going out of my way to hide anything. After a while of us laying there, he mentioned that he was starting to get pretty horny. I looked over and saw that he had sprouted a small boner. Seeing it started to get me going as well. He then got up, grabbed a tissue and asked 'you ever jacked off before?' I sheepishly admitted to it and he said he does a few times a day, every day. He started stroking and said I can join him if I want to. I was a little hesitant at first, but decided to go for it. I grabbed a tissue and sat next to him on the couch and began stroking myself as well.
We were watching a steamy movie on TV and were really getting into it when I heard a car door shut outside. He said it was his mother. Instantly I went into a panic, grabbing a pillow and covering myself, but he just sat there and didn't miss a beat. 'What are you doing? Your mom's here, she'll see you!' 'So?' She then walked in and I held my breath. She said hi and he introduced us. After our not-so-formal meeting, she looked at him and asked 'are you going at it again? You were when I left this morning. What is this, two?' He smiled and said 'Actually, number three.' She laughed and said 'boys...' as she walked up to her room. I sat there in shock as he just kept on going. He then said that masturbation around his house is normal and neither of them try to hide it. Since it's just a way of making yourself feel better, there's no reason to be ashamed of it.
I then slowly moved the pillow and started playing with myself again. A couple minutes later, his mother walked back down, completely naked with a large bush between her legs. She asked if we wanted some lunch and he said 'sure, we'll be done in a few minutes.' She walked into the kitchen and we heard glasses clanging together. He then grunted out 'oh man, I'm gonna cum...' He grabbed the tissue and shot a big load onto it. Seeing this sent me over the edge as well, and I blew the biggest load of my life.
After we sat there for a minute catching our breaths and cleaning ourselves up, we walked into the kitchen and there were a couple sandwiches and drinks waiting for us. The three of us sat there stark naked, chatting about random things and eating our lunch. I had almost forgot I was naked, I was getting so comfortable with it. When we were finished he said 'I'm still really horny, I'm going upstairs to do it again.' He stood up and again had a boner poking out. His mother then said 'again? I swear, you're going to make that thing fall off.' 'Well, I'll take my chances.' They both laughed and we went upstairs. We lied on his bed and began masturbating again when I noticed his mother walk past his room into her own and heard her bed squeak as she sat down. As we were stroking, I could hear his mother moan slightly. She was masturbating too! I picked up and pace and knew I was close to coming. I then heard her let out a loud grunt, causing me to cum all over my stomach. I looked over and he said 'here I come...' and let out a load that went up to his chest. We wiped up and went back downstairs, and his mother wasn't far behind. She came into the living room her hair was a mess and she was wearing a pair of slippers. 'Whew, I needed that after the day I had!' She sat down with us on the couch and we started watching a movie, like nothing had ever happened.
Needless to say, that was not the last time I went over to his house! Now every time I go over, as soon as I walk in I strip down and we all hang out naked and masturbate. Amazing!
