It's nothing new (I have a high libido) that I woke up three weeks ago, hard as rock and needed to wack one off. My wife was sound asleep and had been ill. So getting out of bed I headed downstairs, started my computer tablet and went onto a porn site. Opening my robe I began to stroke my cock whilst watching a porn movie. Getting bored with the one I was watching, I just so happened to click onto one showing a guy fucking his step daughter. I'd almost reached my orgasm when Wendy my eighteen year old step daughter walked into the lounge. She didn't say a damn word. Instead she walked over to me, took hold of my cock and began to toss me off. Noticing the video and its content, Wendy looked right at me and asked if I wished I could fuck her. Unfortunately I didn't get to answer her as my cock let go and I spurted my cum all over her hand and my stomach. Getting up and licking her hand, Wendy smiled and said "Well if you do, you know where my bedroom is".
The past three weeks have been a little awkward to say the least. Not only because Wendy caught me masturbating to a porno of a step father fucking his step daughter, but also because each time we see each other Wendy makes some kind of sexual innuendo. She even only last week flashed me her pussy as she sat opposite me and her mom. Her mom obviously didn't see her do it, but to make sure it wasn't a mistake, Wendy did it twice more.
I have to admit, given I now know she'd like me to fuck her, I'd willingly do so. But the flip side is, I also love fucking her mom too.
