This is a true story, which occurred many years ago with my ex-wife. We had been married about 2 years. We lived in a one-bedroom apartment.
We had a married couple as friends, with my ex was best friends with Carol, the female part of the couple. Carol had confided in my ex that she and her husband were getting divorced. Carol was very distraught about it as they had a baby they had.
My ex asked Carol to come over for the weekend to get away, relax, and have some fun. She and her daughter lived with her parents at this point, due to the break-up. Carol's parents kept Carol's daughter for the weekend.
Carol came over on a Friday night and we went to dinner and had some drinks. We arrived back home and drank some more. We were all feeling pretty good, and my ex said she was going to take a bath.
I was playing a video game in the living room, and I thought Carol was in the bedroom. Soon I heard them laughing and giggling and I went to see what was going on.
I saw both girls in the tub, with my ex in front of Carol. Carol was soaping my ex's tits and rubbing them very erotically concentrating on the nipples. Her nipples were very hard and Carol was tweaking them in her fingers with the soap.
I do want to mention, after we were first married, I came home early from work one day, and found my ex naked on the bedroom masturbating to my Hustler magazine's pictures, of women! I asked her what was she doing, and she was embarrassed. She said she wanted to see what was in these magazines and found them pretty exciting.
I asked her if the models bodies excited her. She said she was mainly looking at the tits and the nipples. It was the first I suspected her of being attracted to women.
Back to the story. They were joking with me about taking a bath together and let me watch as they both soaped each other's tits. I was getting quite aroused watching this.
My only experience with porn by the age of 20, was Hustler and Penthouse magazines at that point.
They rinsed off and got out, getting dressed in their nightclothes. We all went to the living room where my game was on. They asked what can we do now. I suspected they were both horny now. I suggested we play strip poker with the game. After some coaxing, they both agreed.
I was much better at it than they were. So soon they were both naked, again.
After I was naked, purposely losing the game, my hard cock was evident. They both laughed at my predicament. Carol said my cock was much bigger than her soon to be ex husband's. She said my cock's head was much bigger, as his wasn't much bigger than the shaft. My ex said she has never had a problem with it.
