Mother and I spent the first few weeks after my graduation pretty much alone, at least as far as our sex lives were concerned. We were content with each other, enjoying our love. The excitement of trying new things, of learning still more about our likes and dislikes, kept us fascinated.
My new job kept me busy too. It was interesting work. I was learning much. A couple of old timers at the firm took an interest in me. They taught me a lot that I would never learn in school. At least one was going to retire within a few years. I would probably be able to take his place. At least, that is what the firm thought. I liked the idea.
That is not to say we didn't keep in touch with Mother's sisters, Janet and Edith. The wild sex filled weekend of my graduation had been exciting for all of us. We all agreed that we wanted more such family fun. Many of our emails to each other were of a salacious nature. We were all working up to another family tryst.
About three weeks after my graduation, on a Friday evening, Mother and I called Aunt Edith. We invited her to visit for a weekend. We set a date for the following weekend. She would arrive Friday evening. Then we called Aunt Janet and invited her.
A lot had been happening in Aunt Janet's life. First of all, in her marriage with Earl. She had let him convince her to try oral. That was after she had learned how enjoyable it is from Mother and me. It had become a regular part of their sex life.
Uncle Earl was trying to convince her to try a threesome. Aunt Janet was trying to figure out how to suggest Aunt Edith for the third. She didn't want to get involved with anyone outside the family. She said that she was letting Earl think he was slowly convincing her. Like he had convinced her to try oral sex. She and Mother laughed.
Personally, I thought they were underestimating Uncle Earl. I kept my mouth shut, at least to Janet. I did tell Mother what I thought later.
"Maybe I should tell Janet that," she said.
Aunt Janet had other things going on. Things weren't improving for the daughter whose marriage was in trouble. The daughter's name was Michelle. She was about a year older than me. I didn't know her very well, only from family gatherings. She was a pretty good looking woman, like a younger version of her mother. She had been married almost two years. There were no children. I wasn't clear on just what the problem was in the marriage.
Aunt Janet had another daughter, Diane, She was a little over a year younger than me. She was married too, but I hadn't heard of any problems in her marriage. She and her husband lived in another state, so we seldom saw them.
Aunt Janet said she could probably visit on Saturday when Aunt Edith was here. But she didn't think she would stay overnight. Mother had a suggestion.
"Why don't you check with Edith? See if she'd like to go home with you Saturday evening. You could watch a video about a threesome with Earl. That ought to give him the message."
Aunt Janet laughed, "I'll call Edith as soon as I hang up. She always did say she thought Earl is sexy."
Edith emailed us later. What a great idea!
We heard from Aunt Janet on Sunday. Earl had brought up a threesome again. Janet told him that she was thinking seriously about it. She told Earl that she wouldn't feel comfortable with a strange woman. Nor did she have any friends that would be suitable. She told Earl that if she did do a threesome with him it would have to be with someone close. Someone who would not tell tales.
Mother and I spent a quiet week together. Our lovemaking, however, was intense. The anticipation of the coming weekend spiced our sex. We watched porn to look for new ideas to use with Janet and Edith. But, as Mother put it, "We already know about so many ideas we haven't tried yet. Let's not get too far ahead of ourselves. It's so much fun learning new ways to please each other and then practicing them."
Mother was probably right. She was always in favor of learning before moving on. She reminded me that we were having great fun, and beautiful sex, just trying out variations on basic techniques. Basic to some people, that is.
For example, we had recently started playing with vibrators and other toys. We were still experimenting, still in the early stages. But, we were thoroughly enjoying each step of our learning experience.
Friday evening arrived. My Aunt Edith pulled into our driveway earlier than we had expected. She had left work a little early and driven directly to our home.
I went out to help with her suitcase. She gave me a big hug.
"More when we get inside," she said with a laugh. Once inside, she and Mother embraced and kissed each other. It was a hot romantic kiss. She turned to me and did the same.
Both women held executive jobs. Both were dressed in well tailored suits with skirts, nylons and moderate heels. Aunt Edith was slimmer than Mother, who was very slightly plump.
We sat at the kitchen table catching up on news. Aunt Edith mentioned her sister, Janet.
"I think the idea of a threesome with Janet and Earl is exciting. Does the idea of Janet and me going off together bother you? I know it was your idea, but I thought you might have reservations."
"No," Mother replied for both of us. "David and I both think that three is the ideal number for group sex. That is not to say that four, or even more wouldn't be a lot of fun. We already know that from the graduation. We're looking forward to tomorrow, too. When Janet is here.
"For today, though, you are our guest. That means you get first choice."
Mother was seated next to her sister. Her hand was on Edith's thigh, caressing it. Edith's hand laid on top of Mother's, guiding her. I saw Aunt Edith lick her lips, she stood and took Mother's hand. Together, they went to the living room and to the couch.
Sitting on the couch, they exchanged hot kisses. They felt each other's tits. They rubbed thighs. They came up for air and both women opened their blouses. They slipped them off followed by their bras. I sat in a chair watching. My cock hardened.
