Moved in with a girl I was dating when I was 21. Neither of us had plans of marriage, just companionship and sex. In fact sex was what kept us together and almost did it every and some times twice a day. Her cousin Nancy was in the mist of moving from New York to Florida and asked her if she could stay her. Her plan was crashing with us while her boyfriend came down later from New York and find there own place to stay. But Nancy's boyfriend Joe took months to come to Florida and didn't have an specific date of when he would come down. She ended staying with us for five months in a row in the bedroom right next to ours. It was a small apartment and often saw each other in underwear or walking in or out of the shower rapped in a towel, as if it was the most normal thing to do. Became so normal after a few weeks closing doors wasn't a issue anymore. One day Nancy walked up to me and told me she wanted to tell me some things.
"I have a confession to make" she said.
"What about" I asked her.
"I saw you naked through the mirror"
Couldn't believe she said it in front of my girlfriend that did seem to make much fuss about it.
My girlfriend had a full length mirror on the out side of her bedroom door, had left it half way open and apparently she had a clear naked view from the hall while changing clothes. What else could I do, but brush it off and pretend it was funny. My girlfriend later confessed that she was horny for sex and indirectly mention having a threesome.
!What! was the only thing that came to my mind, as she went on telling me she listened to us have sex every day.
"Come on guys have fantasies about that all the time" trying to convince me.
"I take it your alright with it" I answered her bluntly.
"It's just sex" she said, plus it's kinky and Joe will never know.
Spent the day getting hard thinking about and not hiding it very well. Nancy was a sexy girl and knew they both had been taking about and sexual excitement made me give in. I still remember my girlfriend bring in Nancy naked into our bedroom. She was just as beautiful naked as my girlfriend; nice medium breasts, nice legs, small patch of pubes over her pussy and lusting over my hard dick. Don't know witch one's pussy tasted better, but had plenty of it that day. Kept it oral to be safe and spent three hours blowing my mind, having Nancy sitting on my face and my girlfriend riding my dick. It was the most erotic and orgasmic thing I had ever done and the hardest thing to keep a straight face when Joe finally arrived. They moved out a month later, but know the memories still linger on. Maybe know that the ice has been broken, their will be a quickie if Joe ever decided to make a trip. Can't wait for that to happen.
