Your wife gets a lot closer to someone that you know or don't know. Literally!!!
|You, Darren Salvetzi, are married to the love of your life, Carmen Ficqua. Yet despite your and her affection for each other, you both decide to not have official intercourse until you two are both ready. One year into your marriage, she gets a high-paying one-day job to be a little lab rat for a certain medical experiment. To celebrate this triumph, you will have sex with her for the first time. The process of doing the swap could also be done however you want.
However, when that time comes and Carmen comes through that door, you realize that she has a second head on her shoulders or her head is on somebody else's shoulders. The kicker? That second head is the head of someone you know or someone you don't!!!
Sex scenes are a necessity, but not every chapter should be a full on sex scene, there should at least be some build up leading to it. Although it may be one of the main reasons why I created this story, it shouldn't be every chapter. Also be as creative as you possibly can.
Even though the main character is doing his wife and relative at the same time, it is NOT incest. After all, the entire body belongs to Carmen; the main character's relative is just a "passenger."
Also, if you want, you could have Carmen attached to somebody else's body just to make things more, interesting.
