Sister-in-laws Teasing Me

So it all started when my sister-in-law Had a problem with her son's iPad.

I'm not bad with technology so she asked me to take a look at it as it kept freezing and seemed really slow. Thinking it could just be full I asked if I could delete things and she agreed. I clicked the photo gallery and noticed her phone was connected to the tablet.

There was a few pictures of her standing in nothing but a thongs and one of a close up of her pussy. I was instantly hard and decided to take pictures on my phone. I masturbated to those pictures so many times. fantasizing what I would do to her.

When I have the iPad back I mentioned that she should be careful of what's on her phone as the two are connected. She was embarrassed and told me not to tell her sister (my wife). Obviously I agreed.

A few weeks later I got a random Snapchat from her. It was her naked in the shower. It was then followed by apologies, claiming it was for her boyfriend and begged me not to tell her sister again. Of course I wanked to the memory of the picture yet again.

On the following week's when I saw her she often wore low cut tops and tight bottoms, bending over a lot so I could see down her top or showing of her pretty impressive ass. She also brushed past me a couple of times rubbing her ass against my cock. I notice she looked at my crotch to see if I had a hard on. Once I did and saw a little smirk on her face.

Eventually she was alone. She mentioned she had problems with her laptop and asked if I'd take a look. She left the room and the door was open slightly. I noticed a few things open and one of them was a video of her rubbing her boyfriends dick. I rubbed my throbbing dick through my trousers.

I noticed her looking through the gap in the door but she didn't think I noticed. I carried on watching the video as she licked and sucked his hard on. I slid my hand in to my jeans and rubbed harder and harder. I watched as he cum in her mouth and I cum in my pants. She was still standing there.

I bought my hands back out and looked for my pictures or videos but there wasn't anything else. She came in a few minutes later, bought me a drink and asked if I found anything. I said no. She said that's a shame, took the laptop and then both acted like nothing happened.

Since then not much else has happened but I get massively turned on thinking about it. I've cum over her so many times, cum in my wife thinking of her sister. Really wishing I could cum inside her.
