Ryan's stepdaughter Chloe is going to stay with him for a while and shows up unexpectedly. he has no idea that she is going to finally act on what she has felt since she was too young to act on it.

It seems harmless, just let her give him a foot rub

Chloe can't stop fantasizing about her stepdad, she goes to her room and uses a vibrator, moaning loud enough that her stepdad thinks something wrong and comes in

Chloe doesn't even get dressed and follows him to the kitchen, telling him it is MORE than ok

Ryan tells his stepdaughter that it can't happen again, it's obvious she disagrees
