This occurred back when I was 12 and 13 years old. I would spend a lot of time at my friends house. His mother always made him take a bath around 8:00pm everyday. My friend was a year younger than me and also had a younger sister who was 3 years younger than him. The 2 of them would always have a bath together and for about a year or so I would be in the bathroom talking to them when they were doing so. They would be naked and I would be dressed and their mother never told me to get out of the bathroom so I kept going in there.

One weekend my parents were going to be out late on a Saturday night so my friends mother offered to have me stay over night at their place. It was 8:00pm and time for their bath again and I went in to talk to them like I always did. This time his mother said there were clean sheets on the bed and I would need to have a bath too. She told me we better get me ready so when they were done I could quickly jump in. She took me to the bedroom where I would be sleeping and told me to undress. I was a little shocked by her request because I realized I would be seen naked now but slowly began to undress. I think she noticed my reluctance to take off my last piece of clothing, my underwear, and told me I had seen my friend and his sister naked and it was my turn now. I realized she was right and took them off and there I was 13 years old standing naked in front of her. She told me I could go back to the bathroom until it was my turn. I walked naked back to the bathroom and for the first time my friend's younger sister saw me naked. I thought it was going to be a bigger deal than it turned out to be. She looked and said I was naked and that was all.

The bathroom door was always left open when they were bathing and there was my friend and his sister in the tub and me outside of it talking with them. My back was to the door and I hear someone ask what was going on in here. It was his 15 year old sister. She was seeing me naked now and I had no way to hide. I was getting very uncomfortable with her seeing me naked. To make matters worse she had a girlfriend with her. I could see his older sister was enjoying seeing me naked more than his younger sister was and her friend was enjoying seeing both me and my friend. His mother must have heard us talking and came in too. She told the older sister that she didn't want them in here when her brother and sister were bathing naked. She told her she didn't want you 2 girls seeing your brother naked. She said once her brother and sister were done that they could come back and keep me company when I was having my bath. I didn't know what to think with that comment. When my friend and his younger sister were done they left the bathroom and his mother drained the tub and began refilling it for me. I asked about her comment about letting her older daughter and her friend come back when I was having my bath. She said she didn't want them seeing her son naked and hoped it wasn't a problem for me having them see me. I told her I didn't know if I wanted them seeing me naked. She said for the last year I had been coming into the bathroom and watching her younger daughter naked and now it was going to be my turn to be watched. She went on to say she knows how boys like seeing girls naked and now some girls were going to see a boy naked. With that she told me to get into the tub.

I got into the tub and within a couple of minutes my friend's older sister and her friend were in there. I was naked and they were watching me. At first I was uncomfortable but as time went on I just accepted it. They were looking at my penis and making comments about it. A few minutes later my friend and his younger sister come in. I was now naked in front of 4 people. With them showing up the penis comments stopped but I could still see the girls looking at it. It was about half hour later when I was finally done and got dressed.

The days that followed had his older sister and her friend tease me about how they saw me naked.
