Technically my mom was the one babysitting, I was just there. Anyway she was upstairs with the baby and I was in the finished basement playing some game on my uncle's Commodore 64. I took a break and was poking around his office when I found a copy of The Joy of Sex. I was looking through that when I was called upstairs for something. Later I was back downstairs this time in front of the tv. I started digging through a basket next to the couch looking for the tv guide when I found a few Penthouse Variations type booklets. I nervously looked through them hoping my mom didn't call me upstairs again or worse come down and join me.
I seriously thought about bringing one home for some alone time in my room but decided it was too risky with only 3 of them in the basket. I can still vaguely remember my favorite photo spread of a brunette undressing on the back of a horse. It was one of those "she's the most beautiful woman I've ever seen. I'm in love moments."
When my aunt and uncle got home I also remember thinking "you kinky fuckers." Meant in a good way of course.
