A few weeks before my friend and I were going to set off to start university, our families visited a water park together. My friend and I had a concert to attend later that evening and his mom was going to drive us to it. The three of us finished up at the water park earlier to head to the concert. The changing rooms there were coed and with individual stalls. There were separate line ups for each stall which were pretty long. We decided to line up for the same stall so we could stay together. It took forever for us to get to the front of the line and all three of us were really worried that we might not make it on time to the concert. When my friend's mom's turn came to go into the stall, she said that we should all go in together to save time. I gladly agreed not wanting to waste anymore time.
As soon as we got into the stall my friend's mom slipped off her blue one piece bathing suit and hung it on a hook. She didn't seem the least bit worried about nudity, which surprised me as I'd known her for 3 years and not taken her to be so relaxed about nudity. All three of us started to quickly dry ourselves. My friend's mom stood in front of us with her towel over her shoulders going through the bag to take out clothes for herself and her son. I was no longer worried about the concert, just happy to be getting to see this lovely woman naked.
She had a curvy body with very pale and smooth skin. I was standing pretty close to her and could not make out any hair on her body below her neck. She had big rounded boobs with large nipples that were about the same color as her skin. She had a bit of a belly. I was very surprised to see how youthful her naked body looked. Certainly a delight for the eyes. We got dressed and hurried to leave. Just then, I told them I had to use the washroom quickly. I went in there and it didn't take me more than 3 secs to release a load thinking of the naked lady I had just seen.
Later I asked my friend if it's common for his mom to be naked in front of him and he said that it was the first time he'd seen her naked since he was a little kid. I was very surprised to hear this. I joked with him and said "maybe she wanted us to know what a real woman looked like naked before we go off to university".
For many years, I would tease him about having seen his mom naked.
