I had moved in with my girlfriend a few years before, she had a 10 yr old daughter who I spent many hours with, in only a fatherly fashion, after a few years the girlfriend and me had split up and I was living alone in a small flat. My x stepdaughter used to visit quite regularly.
I had noticed her growing and she was becoming a beautiful young lady and at 18 she certainly had plenty of guys in tow and I had heard some rumours around the local pubs that she liked to put it about a bit. I also heard a rumour that she claimed that her own dad had raped her a few years earlier.
I was obviously quite stressed about this and decided that the next time she visited I would confront her with all the rumours going round.
This day finally came which found her sitting opposite me in my flat, I was nervous on how to approach her and started off with the talk of her putting it around a bit. I expected her to be shocked but she was quite blaze about it and said that she liked sex and that she had fucked quite a few guys and even that she watched porn every night and masturbated to it.
I had started getting quite turned on by her dirty talk and she must have noticed me shifting position to hide my growing erection, that's when she got her mobile phone put and said come and look at this. As I stood and walked across the room she was staring directly at the bulge in trousers. On the phone there was a video of one girl getting double ended by two guys, the girl looking very similar to my step daughter.
Is that you?
She said she wishes but that she knew the girl looked like her and often showed the video in the pub pretending it was her.
Your bad.
oh I'm worse than bad she replied.
We both laughed. That's when I came out with it.
I know what your dad did!
She went very quiet and for the first time seemed lost for words.
