It was a hot summer day when mom suggested we go over to a friend of hers house and go swimming. I grabbed the new white bathing suit she just bought me. It was a skimpy little tight fitting suit. There was no way you could wear a jock under it.
When we arrived and had completed all of the formalities. I went to the bath house to change into my new suit. This was a unisex bath house. My mom walked in just as I got my suit on. We engaged in some conversation as she laid out her bathing suit and removed her blouse and bra. I left the bath house and went out by the pool. As I got to the pool her friend walked down from the house after changing in to her suit. It was some suit, three postage size pieces of material covering her breasts and crotch.
Soon after her arrival mom came out of the bath house her suit didn't even cover as much as her friends We all got in the pool and splashed around for thirty minutes or so and started getting out of the pool. Mom and her friend both had white suits on. As they stood facing me I noticed that there tops and bottoms had become transparent. You could clearly see their nipples and pussies.
When I stepped out of the pool it was a diferent story. My suit had become transparent,you could clearly see my dick and balls in every detail through my suit. The two of them watched as I got an erection. I went into the bath house to change.
I quickly got out of my wet suit,dried off and started slowly stroking my hard dick. Just as I reached the commitment point moms girlfriend walked in. She said your mom said you would be doing this and quickly took off her suit. She stood there staring at my erect penis then started stroking my dick for me. It felt so good. It seemed like only a few seconds and my dick erupted. It was really great.
