I tricked my sister in law [F] into looking at old photos of me fucking her sister [MF]

Years back my wife’s little sister was visiting us from out of state. It was cool because we had been together since we were kids, I had even briefly dated her sister before I got together with my wife in like 9th grade. Nothing serious, but obviously we were all close. She was cute, and we probably flirted a little more than we should have, but no one ever took it too far or got upset, it was all harmless fun.
But all that flirting was definitely a turn on. I wasn’t about to start anything up but I did really enjoy the attention and the sexual tension. With that in mind, I came up with a way to excentuate that while getting to show off a little as well.
Back in highschool, I had gotten to take a photography class, which was nice because it gave me the chance to develop my own film. Back in the day before cellphones this was the only safe way to take nudes, especially in highschool. I had quite the collection ranging from classy artsy stuff, to spread eagle, and crummy blowjobs. My girl had taken some very flattering closeups my dick at the time as well. I have a small box of some of my favorites I keep handy for jerking off with.
My plan was fairly simple. I took this box, and I moved it to the cabinet under the sink in my guest bathroom. Next I would stage the toilet paper to be on it’s last square just as her sister was about to go in. She would ask through the door if I had anymore. I would tell her to check under the sink. I had indeed put a roll under there, but I had also had the box of photos placed precariously behind it. Removing the roll insured the box would fall out, spilling the photos all over the floor. So now, she is in a locked room, with her phone, and a whole box of amateur porn of me and her sister. I have even subtly placed a hair on the lid of the box, that would tell me for sure if the hair had fallen off, the box had been opened.
Well I set everything up and even though she seemed to be feeling fine just before, the little sister would up spending a full 30 mins in the bathroom that night…. I later checked, and not only was the hair gone, the photos were all out of order. I absolutely LOVE knowing that she was going through all the photos. I wonder if she just looked at the naked pics of me, or she was looking at her sister as well. I wonder if she got turned on seing my cum in her sister.
