My wife (Amanda, 38) and I (John, 39) have been together for 20 years and have 18 year old twins (a son and a daughter). When Amanda became pregnant she confessed her secret family lifestyle.
When we first started dating, Amanda lived at home with her parents (Alan and Donna) and her brother (Jason). Her sister (Erica) was older and moved out to live with her boyfriend and their son.
Amanda was sitting in class on a Friday morning thinking about how excited she was for the weekend. We had plans to see a movie Friday night, Saturday she was planning on spending time with her friends and Sunday was family dinner day. Her family was always really close but little did she know how close they really were.
Amanda decided to skip her afternoon classes and get an early start on the weekend. When she arrived home, Erica's car was in the driveway but that was not out of the ordinary. Amanda walked into the kitchen and made herself a snack and started walking to her room. As she went to the walk up the stairs, Erica walked out of their parent's bedroom in just her bra and panties carrying her clothes. They both stopped and stared at each other for a second and then Erica said "hey" and walked into the bathroom. Amanda went upstairs to her room and while she had several thoughts going through her head, she didn't actually see anyone else in the room so she gave it the benefit of the doubt and said maybe she was just in there changing.
About an hour or so later, Erica knocked on Amanda's door. She came in and sat on Amanda's bed and asked if they could talk. Erica said that said she noticed Amanda looking confused and confessed that it was in fact what she was thinking. Erica was in their parent's room having sex with their father. Amanda was shocked but not totally disgusted and actually more intrigued. Amanda asked Erica if she enjoyed to which Erica said it was quite enjoyable. Although the confession shocked Amanda, she was not expecting Erica's next confession. The family has a very sexually open lifestyle and many of the members are sexually involved. In fact, family dinners were a time for people to hook up. Amanda was completely shocked but yet still very intrigued.
Erica's next statement weirdly excited Amanda. Erica told her now that she is 18, it was time for her to decide if she wanted to join the family lifestyle. Erica explained how fun and exciting it could be but that it also came with consequences. Erica told her that she was going to take their mom to dinner Saturday night and Jason had plans with his friends. Erica told her that their dad would be waiting for her in his room if she chose to join.
Amanda thought about it all night at the movies and all day Saturday. Erica picked up their mother and whispered in Amanda's ear "give it a try. You'll like it. Oh and by the way, dad really likes you in those jean shorts and white shirt you wear." Amanda felt torn. On one hand, this was her father and just wrong and weird. On the other hand, if everyone was doing it and enjoying it, maybe it was worth trying.
Amanda walked to her closet and grabbed the shorts and shirt her dad liked. She was surprisingly turned on by the idea of her father checking her out. She decided to put on the outfit and decided she was going to try it.
