Okay I will admit right up front this is stolen. But it was an interesting one when it was talked about but a difference of how things were seen, okay I am not as thought provoking to have a line to follow, I like to see where it goes. But the idea is great and the other, is a great writer, we just can't work together. No ill feelings though.
Younger couple, both kind of shy, married but they pretty much do the basic, she might suck him off but never is he allowed to cum in her mouth or on her, they only do it missionary style.
Think modern day Cleavers..... They were brought up that way, maybe by very religious families so they never really talked about sex or what the other liked. They were always told sex was dirty only used to procreate. She finds sites on the internet, he finds she is looking at them, perhaps talking to others about things he didn't have an inkling she might like.
Of vice versa on that, but you get the feel of the RP
If interested send me a message. I know this is confusing.
You might want to look at my ons/offs
This is just an idea I am open to many others.
