I Fucked My Stepdaughter When My Wife Wasn't Home

Last week I went to my step daughters bed room to ask her about a book she borrowed a while back since one of my friend was asking for it. She was wearing a sweater and just her panties so when she reached to grab it I couldn't help myself but to have a good look at her ass. Not gonna lie its a nice, it totally got me distracted and she caught me staring at it, I just didn't want her to tell her stepmom about it but instead of being mad she was turned on and starting reaching for my pants and my dick. I wasn't really sure where she was going with that but apparently she wanted to experience what shes been hearing about from her stepmom. Thankfully my wife was running errands and wouldn't be back home for a couple of hours so I couldn't help it and fucked her. Shes a natural just like her stepmom! It felt so good that I finished inside of her.
