I Looked Through My Sister In Laws Phone

I am an IT professional, so naturally my family tends to ask me to do their IT related tasks. I have no problem with this. One time I was at my SIL's house, and they just got a new router, a bunch of chromecasts, and google homes. She asked me if I would setup all their devices for them. Part way through the process, I needed her phone so that I can login to her account and finish setting up their services and such. I wouldn't have even thought of doing it if she wouldn't have said anything, but she said "Don't go looking through the phone though, you might find something you don't want to see." I just laughed and said I wouldn't. Now, my SIL is hot. Like seriously compared to my wife. There was a point where her sister admitted in a conversation between us that she was jealous of my wife because I was such a good husband compared to hers. It was an honest admission that didn't mean anything. That being said, I felt like her telling me not to look through her phone was a challenge. A part of me thinks she secretly wanted me to. I started going around the house setting up the devices. I did it legitimately for a few, but I padded the amount of time it took at each one to make it seem like there is a "long" process for each device. This would account for the "extra" time i would be spending on her phone. I went through her photos. About 90% were pictures of my nieces and nephew, usually ones I have seen on social media. Then I found them, the ones I wouldn't want to see. She was somewhat right, there were several of her husbands man parts, so there were some I didn't want to see. However, there was a treasure trove of pictures of her breasts, pussy, and ass. There were just regular topless shots, there were spread eagle shots of her masturbating, and there were shots of her ass up in the air staring straight into her pussy and asshole. It was wonderful. I used a little bit of my anonymous IT magic so that she wouldn't know, and sent them to myself. To this day, I have a hidden encrypted folder that only I have access to with these pictures. If I die, they die with me. What is more, I have had several more chances since that time to do this again. I have helped with some IT items for her that required her phone. My folder has grown quite a bit over the years with some very nice fapping material for myself.
