Due to my frequent travels, my wife and I have an agreement that we are allowed to satisfy our sexual desires as needed. Some call this an open marriage, we didn't put a name to it but I guess that's what it was. Angie is a very sexual person and had taken on a couple regular lovers. She was able to satisfy them and still take care of my needs too when I was in town. We always were open about things that would happen but I was caught off guard one morning when Angie told me that her boyfriend had his son with him when she showed up at his apartment one night.
She said at first she was a little ashamed at the way she was dressed (she almost always just wore a night gown or something like that. It was always sexy but not enough to get her arrested for public nudity. She had worn a sheer top baby doll that night with a very small sheer panty and no bra. She said her bf explained to her that his son was going to spend the summer before starting college living with him. He also explained that he thought maybe they could teach the boy some things over the summer.
My wife looked him in the eyes and asked if he was asking what she thought he was asking and he nodded. This set her back a little but she ended up going through with it by having sex with the father in front of the boy and then touching him and eventually with some encouragement she sucked the boys cock until he squirted in her mouth. After squirting he explored my wife's body while his dad fucked her to his orgasm.
My wife was so turned on by everything and seeing that the boy was still hard she allowed him to move into the position that his father had just vacated. She was surprised that even though this was his virginal fuck, and he was smaller than his mature father, he was very good and provided her a lot of pleasure.
Over the next few weeks Angie ended up making a few extra visits to her bf's apartment and sometimes only spent time with the boy. She ended up admitting to me that the thought of a younger cock sent her into orbit.
After several months, it was time for college to start and the boy left. The sex between Angie and her bf was never the same and they ended up breaking up. She finally asked me one day if I thought she could find another young boy to have a relationship with. I asked her how young she was thinking and she just said "as young as the law will allow", with a blush on her face.
We innocently mentioned to one of our married friends who we had swung with a few times about our search and they seemed to get a twinkle in their eyes. Angie was intrigued and asked what was up. The couple said that they had noticed their 18 year old son spending more time in mommy's room while she was getting dressed/undressed. She didn't mind as she spent a lot of time nude in the house but she decided to tease him a little to see what he would do. She started by asking him for back or leg rubs while she was nude or nearly nude and had let him watch while she waxed her bikini line. She said there was almost drool hanging out of his mouth and even though her husband had said it would be okay for her to fuck him, she just couldn't bring herself to go that far. She asked Angie if she was interested and Angie almost orgasm on the spot. Danny's mom mentioned that his birthday was in about 3 months and maybe it would be nice to take his virginity on his 19th birthday.
