Saw the movie 17 again last night and it got me thinking while it wasn't a great movie it could be a really good erotic story.
For anyone interested the movie is about 37 year old husband who gets transformed back into his 17 year old self but still in the modern day / normal timeline, aka no doover, same body just younger, wife and kids are still the same age, etc.
If something like this already exists please forgive me.
