Sara and I were living with her mom. Sara had taken a job back home and until we could get our own place, we lived with her mom. Lisa's, Sara's mom, husband had passed away 8 years before and she lived alone until we arrived. Her house was large with two master suites, so the house was able to accommodate us easily.
One night, 3 months after moving in, Sara and I were lying in bed in each other's embrace following sex. As we were pillow talking, Sara said she had something she needed to tell me.
She began, "Our living here has created a problem for mom. She has heard us having sex. I know I can be a little vocal when I climax and she has heard that and it has created a problem for her. Since dad died she has not had a man for 8 years."
"So, I guess that means that I am going to have to cover your mouth and muffle your sounds?" I jested. "I kind of like your moans and groans. Makes me know that I am being successful."
She punched my arm lightly with her fist. "No," she said, "We..I..like making sounds too. So I am not getting quiet. But that is not the solution to the problem."
"So, pray tell, what is the solution?" I asked. "We need to find her a man?"
"That would be the long term solution," she said. "We need to help her with the whole finding a guy, dating and all that stuff. She has been out of the loop for a long time. It is the short term solution we need to work together on."
"What is the short term solution?" I asked.
Sara smiled at me very coyly and said, "My Mr. Prince Charming, you are!"
Sara went on to explain to my wide eyed, raised eyebrow expression, that she had explained to her mother that we had an open marriage. That although we had not practiced it, that is, we had not slept with anyone else, we had agreed that the circumstances being right, we would both be all right with it. Sara went on to tell me that she had promised her mother that it would be all right with her if her mother and I had sex. I gave Sara a blank stare. I did not know what to think. While Sara continued to talk, my mind tried to envision doing it with my mother in law.
Mom was in her mid 40's and was a beautiful woman. One reason I married Sara was her mother. Upon meeting her the first time, I thought, that if this is how Sara will look someday then it was more than all right with me. She was of medium build with right sized breasts. I had seen her several times in a bikini swimsuit, not a teeny tiny one by any means, but still a bikini and I liked the muscles in her calves and thighs. Her waist and hips were beautifully curved and her arms and shoulders were shapely. Her neck was smooth and her face as beautiful as Sara's. I could very easily see myself having sex with her except for one thing. She was my mother in law!
"So, what do you think?" Sara asked. I had not listened to her last few comments as I was lost in thought about having sex with her mother, so I really did not know what I was responding to specifically but I did respond.
"Sara, your mother is beautiful, just like you. If her naked body looks anything close to yours, then it will be no problem. The only problem I see is....she is my mother in law! I do not know if I can do that."
Sara frowned and then looked away from me. After a moment, she looked back and said, "I want you to do this for mom. If not do it for her, do it for me. I want this to be my gift to her for all she has done for me and for us. I want you to do this. Please. After all, you are simply meeting her sexual need. It is not like you are falling in love with her or anything like that. It is just sex."
After a few more minutes of talk I, half reluctantly, agreed. Sara said, "Mom has a flesh colored dress that dad bought a long time ago. She would wear it around the house just for him. It is a stretch type material that grips her body and it is kind of see through if one really looks closely at it. It is backless and the front plunges down between her breasts. It has a slit up the side of one leg. I told her that when she is ready, she simply needs to wear it one day when you are here and it will be her signal to you. She does not have to say anything, just wear the dress."
For the next few days I got up each day wondering if this would be the day. Mom seemed more attentive to me, more happy, smiling a lot more but, those times we were alone in the house, while Sara was at work, did not materialize into a sexual encounter. Each night Sara came home the first question she would ask me was if anything happened that day. When I told her that nothing occurred, she frowned and wondered out loud why she was waiting.
"It is probably a hard decision for her," l said one night. "She is trying to suck up some courage."
Later that evening, the three of us, sitting at the dinner table, Sara asked me, "Do you have any appointments or interviews tomorrow?"
"No," I replied, "I will be home all day. Anything you need me to do for you while you are at work?" Sara shook her head and said, "No." Then looked at me and winked. She continued, "Mom, Dave is home all day tomorrow so if you need him to help you with anything, tomorrow is a great day."
"Ok, I will keep that in mind," mom said.
In bed that evening, Sara was super sexy. She told me she knew that tomorrow would be the day for mom "to come out." That thought made her very horny and we had sex. Sara was super loud with her first orgasm while I had a mouthful of her clit sucking her deeply into my mouth. When I entered her she came again in a few minutes digging her fingers into the skin on my back. I was sure that she had scratched me to the point of drawing a little surface blood. My opinion was that the thought that her mom and I would have sex tomorrow while she was at work stirred her passion.
When I rolled off of her, having spent myself, she snuggled into me and soon fell asleep. I held her lost in my thoughts and wondering if tomorrow was the day, how would it go. I played different scenarios in my head but knew there would be no real planning for the moment with her mom. It would have to play out as we went along. I fell asleep.
Morning arrived and Sara got ready for work while I prepared breakfast. We kissed and she was out the door. As she left, she called out to her mom, "Remember Mom, Dave is home all day today. I love you."
I went back to our bathroom and showered and cleaned up. Put on a pair of shorts and a T-shirt. I came out into the den picked up a magazine pretending to read it while waiting on mom. After a few minutes she walked in. She was wearing the dress.
She crossed the room and I looked up. Sara was right. The dress clung to every bulge and curve of her body. Although I could not see through it I could make out the splendid protrusion of her breast and sweet curve of her butt. She continued into the kitchen and went to the counter and stood there with her back to me. The back of the dress was open as Sara described down to just above the top of her butt cleavage. Her cleavage was clearly evident through the dress. She had a beautiful contour to her back and her skin seemed clear, smooth and inviting. Her hands were in front of her on the counter and she acted as if she were doing something with her hands.
I sat still for a couple of minutes and then said, "I really like your dress." She responded just above a whisper, "Thank you."
I got up, put the magazine down and walked to her. When I got to her, she remained still, facing the counter, her head down a little. I took a deep breath and put my hands, one on each shoulder. I ran my hands down the outside of her arms to her elbows and she let her arms fall to her side. I continued down her arms to her hands and I squeezed each hand in mine. Then my hands started back up her arms to the top of her shoulders. Over each shoulder was a part of the dress that connected the front of the dress to its back holding it up. I pulled each strap off over the outside of her shoulder and held them there. Then I moved closer to her and planted a kiss at the base of her neck. I continued kissing from her neck along her shoulder line out to the edge of her shoulder. These were slow soft kisses. Each one was planted slow and deliberate. Finishing kissing along one shoulder I retreated to the other side of her neck and did the same thing on the opposite shoulder.
