Situation and summary of the first two parts: Sam and Susan have two grown daughters. Betty is married to Bob and Barbara is going to be wedded to Bruce. This family shares sex with each other, including Sam having sex with his daughters. Also, Susan is pleased to have two sons-in-laws who go to bed with her.
Many guests were attending Bruce and Barbara's wedding. Of course, Bruce's parents, Jane and John, were present.
After the ceremony, Jane whispered to Susan, "Let's go outside where we can have some privacy. I have a question."
Susan and Jane walked to a corner of the yard away from other people.
Jane turned to Susan, "My son mentioned to his dad that your family has an unusual family arrangement. Bruce said that he was in bed with you. Is that true?"
Susan looked a little embarrassed, but knew she had to tell the truth, "Yes, your son is a very good lover, too."
"Does Betty know that Bob is in bed with her mother?"
Susan decided to tell everything, including Sam having sex with his two daughters.
Jane could hardly believe what she heard, but then said, "That does sound interesting. My husband, John, got rather excited and told me it could be an interesting relationship. He was suggesting we might join your family. We didn't know your daughters had sex with their dad."
"Yes, they seem to love their dad so much, they really enjoy being in bed with him. I think it is a nice relationship since it is all in the family."
Jane pondered a minute before asking, "Do you really like being in bed with your two sons-in-laws?"
"Yes, they both are good lovers. Sam isn't too active in the bedroom anymore. These two younger men can get a much harder erection and are much more vigorous. I really love having orgasms with them."
Susan continued, "Now that Bruce is married to our Barbara, you are a part of the family and I know you and John are welcome to join us. Bruce and Barbara are not going on their honeymoon right now, so both of our families can be together tomorrow evening. I'll invite Bob and Betty over. I think you will find Bob is a very good sex partner. He is young and vigorous. I'll suggest to Betty that she pair up with John. I think she will agree."
Before going back to the party, Jane said, "I was a virgin when I married John. He is the only man I've ever been to bed with. John and I have recently discussed getting involved with another couple, so this will be a first time for me. I want to try it."
Later when Susan had a chance to talk to Betty and Bob, they both agreed to pair up with Barbara's parents.
Betty chuckled as she said, "If he hasn't had sex outside of marriage, it will be fun to break him in. It's sort of like finding a virgin."
Both families gathered the next evening at Sam and Susan's home. For at least an hour, drinks were being passed around until everyone was feeling fairly good. Then the subject of sex came up.
Susan announced, "The wedding of Bruce and Barbara merged both of our families together. Our family has been completely comfortable and happy to share love and sex. I feel that we now have an extended family. To initiate our new couple, John and Jane, into the family group, Betty and Bob have volunteered to pair with them. After they go to the bedrooms, the rest of us can continue to have another drink or do whatever comes naturally."
Everyone laughed since Susan's voice was affected by the drinks.
Bob and Betty got up, went to John and Jane and disappeared down the hall. Once Bob entered the room with Jane, he noticed she looked very nervous.
Bob said, "Don't be nervous. I heard you have never been with another man except John."
She seemed a little reluctant to talk and kept her distance from Bob
Bob suggested, "Let's just sit down together on the bed. We'll take it slow."
Bob put his arm around her waist while sitting on the edge of the bed. He turned to kiss her cheek and neck. Then she turned her head for a kiss on the lips.
She said, "Go bring us another drink. I want to get drunk so I can loose my inhibitions."
While Bob was walking through the living room to the kitchen, he noticed the only people left in the room were Sam and his daughter Barbara. Sam had his pants off and Barbara already had removed her blouse and bra. Her ample breasts looked very inviting.
Bob asked, "What are you two doing in here?"
Barbara responded, "The bedrooms are already filled up, so we volunteered to stay here."
As Bob was walking toward the kitchen, he noticed Sam was kissing his daughter's breasts.
Bob fixed two very strong drinks and returned to the living room again. He noticed Sam was completely naked now and Barbara was down on the floor in front of him with her dad's cock in her mouth. Bob decided not to bother them and immediately went on down the hall to be with Jane. He passed the bedroom door where his wife of two months was in bed with John. Bob listened for noises but didn't hear anything.
He entered the bedroom where Jane was waiting for him. She had already partially undressed and was sitting up in bed. Bob handed the drink to her. In a very short time, her drink was gone, but Bob took only a few sips. He wanted to stay sober and enjoy his time with Jane. He noticed she was getting very tipsy.
Bob asked, "How do you feel? Have you had enough to drink?"
Jane was slurring her words as she said, "I'm doing just fine big boy."
Bob was a little surprised at her words.
