There really isn't much sex left in the story.
***
Kim gets pregnant and decides to move to the states. Suzie also gets pregnant around the same time. Debbie and Bobby decide now is a good time for them to have one as well.
Suzie and Henry are first welcoming their daughter Angela.
Kim and Johnny have a son. They were going to name him Johnny Jr.; however, Kim changed her mind and Johnny went along with her wishes. Her departure to the states created some hurt feelings with her parents. So to mend things with them, she named their grandson after relatives. His middlename was Cecil after her mom's father. For his first name, she selected a great grandfather of her Papa's that was a hero. The problem was that there wasn't an English spelling to his name and few could pronounce it. But that was what she named him! But everyone just called him junior.
Debbie and Bobby had a son they named Ben.
Until the baby was born, Kim lived with Suzie and Henry. In the beginning, she wasn't going to have sex with Henry and Bobby unless Johnny was there but Henry seduced her one evening and she gave up on that. Johnny never expected her to abstain just because he wasn't getting any.
After the baby came, she moved into her own place. Johnny had kept his Cabana and his naval housing allowance went to that one. However, years of earning a full time salary and living with her parents had allowed Kim to save a nice little nest egg. She already had some real estate so she decided that Johnny's cabana was a better investment and bought it rather than a house in the states.
This turned out to be a good idea because she did not like living alone with the baby. She was so lonely and horny that she practically raped Bobby one day when he stopped by to check on her.
After that, she went to live with Suzie and Henry and acted as a nanny for the children. One evening, the two couples decided to name Kim as the head of their household. Kim objected but they had good reasons for doing this and she agreed as long as she continued to be the nanny.
She decided she wanted Debbie, Bobby and Ben to come live with them too; however, the house was too small. So she bought a really big house on a couple of acres. The house had several suites and a nice multi-room suite Kim used for the children. There was room for expansion but it had more than enough room for the 3 couples and their children. [Technically, Kim was only a couple when Johnny came home but that is just a detail.]
A female seaman named Gabby became interested in Johnny. Johnny's duties made wearing his wedding ring hazardous so he stopped wearing it except when he went home. Gabby only noticed that Johnny was obviously married and didn't wear his ring. To her, that was a sign of a married man looking to score and she was willing to have him score with her. Except he showed no interest!
So she sat down with him one evening and talked with him. When she tried to get him to go someplace private, he declined. He then told her that he couldn't have sex with anyone his wife had not met and approved of.
Not used to being turned down and intrigued by his wife, she decided she really didn't have anything better to do. So she flew to the states and met with the woman. She told Kim about her family - they were an Army family - and of her own love for the Navy. As a child, she secretly rooted for Navy. As a teenager, she loved the Army/Navy game as it gave her a chance to sneak off and spend time with the Navy men and watch the game with them. After one Navy victory, she celebrated by giving up her virginity. Her family disowned her when she joined the Navy.
