One Click Chicks Forum - What happened to the pictures?

I had a fling my junior year of college with a girl that lived up the street with me, Nancy. All of the guys in the house had known her since freshman year in the dorm. We hooked up about halfway through spring quarter on a Friday night, this started about a week later on Saturday. I had gone over to her place, the plan was to study a couple of hours first, but we ended up naked on the couch fairly quickly. Anyway, I was sitting on the couch, she was kneeling in front of me giving me head when I noticed a polaroid camera on the side table. I picked it up and took a picture, she didn't even flinch. As I was about to cum, she started jerking me off with her mouth wide open and her tongue sticking out looking right at me. I took another pic as I came and caught a frozen rope impacting her tongue.

Over the next weeks, I took pictures of everything we did and we did a lot. Bondage, oral, titfucking, facials, etc. We were a couple of horny young kids. I ended up with around twenty pics, which she made me swear to not show anyone. I agreed and told her I was going to stash them in the back of my closet and only use them for jerking off when we couldn't get together (and for the rest of spring quarter that was maybe once). Our relationship ended when she went home for the summer (it was mutual) but I still had the pics.

After graduation, I moved back home with my parents as I was starting grad school in the fall. I had the pics properly stashed at the bottom of a box of stuff I had moved home. I spent part of the summer going through crap I had kept from my high school and earlier days and threw a lot of shit away. Once I moved into my apartment, the envelope of pics wasn't in the box I had been keeping it in. So here's the question. Did I accidentally throw them out or did my Mom find them while cleaning? I'm sure she wouldn't have confronted me about having polaroid pics of hard core sex acts. And my face was visible in a couple of them.
