My Son’s Best Friend Part 4 His Mother Joins the Party

My name is Jackie, and in the My Son’s Best Friend Part 3 story I told you about my experience with a double penetration with Zack – my son Ricky’s best friend – and Ricky, rewarding Ricky’s brilliant Chemistry grades at school. It was a new experience for me and the most intense orgasm I ever had.

As I mentioned before, I occasionally had sex with Zack or Ricky, but I avoided the three of us together and I also did not favor sex all the time with them: I didn’t want them to be too used or addicted to doing sex with me instead of dating girls their own age. However, in some special occasions we had some good times together, and I enjoyed it!

This adventure began when, on a Saturday afternoon, I saw Karen Carter, Zack’s mother, at the supermarket. Me were not close friends, but we knew each other from the neighborhood and from the boys’ school activities, so she came to say hello and told me, smiling, that she was jealous of me. I froze! Did she know about what I was doing with her son? But she continued, and said that Zack spent more and more time at my house and was much happier than usual.

We kept chatting. She apologized for getting it off her chest, but she was feeling lonely, her husband was too busy, travelling all the time and hadn’t shown up in weeks. She looked depressed, the poor woman. I felt sorry about that – and a bit guilty, for stealing her son – and I invited her and Zack to spend Sunday with us. The weather was nice and we could enjoy the swimming pool and have a couple drinks and lunch together. She gladly accepted, saying she really could use a relaxing day without any worries for a change.

They arrived around noon on Sunday, and I was already at the pool area with Ricky. It was a glorious, warm, sunny day. I welcomed her with a white cover-up that accentuated my suntanned skin, which I removed to reveal my sexy yellow bikinis with revealing triangle tops – showing a lot of my big tits – and small tie thongs. I invited Karen to join me, showed her where the dressing room was, and relaxed in the lounger to get some sun. I saw she looked surprised at the way I was dressed, but I was at home and I was not going to change my routine.

Karen arrived at the house in an elegant blue beach dress, and when she came back from the dressing room she was dressed in fancy one piece dark blue swimsuit and a sarong. She is a well-known lawyer from a traditional firm downtown, and I was sure she was a conservative person. Karen is a beautiful woman, with a graceful and elegant walk contrasting with my sensual way. She is very tall, slender, small boobs that look firm, and an elegant waist in harmony with her bust and hips. Her blonde hair matched her pretty green eyes and expressive face. Her hands and feet are graceful and well cared, and her legs long and well-shaped. She was so white that, on second thoughts, I decided to set an umbrella for us.

She sat close to me and we started chatting and enjoying a pitcher of margarita, while the boys played ball in the swimming pool. After several cold drinks, very refreshing in that warm day, and already in the second pitcher, the chat became more intimate and personal: I started talking about my live as a divorced woman, and she told me about how frustrated she was feeling.
