This Christmas weekend, I went up to my inlaws.

I'm just under 25, my wife is a year under me, and she has a 13yo sister.

Last time I used my little sisters panties to jack off. This time we were cuddling and playing horror games, it was mostly just the two of us in her bed all weekend.

Day one she wore a T-shirt and panties, I ended up groping her tits because she would touch/slap mine.

Then when she fell asleep I played with her butt. All above her purple panties of course. Then day two night two, we were between each others legs while cuddling, our legs intertwine so my knee was against her crotch. I moved around as much as possible to play with her. Then she slept, I woke up horny and got bold enough while she slept to caress her tiny little slit above her PJs. She smelt young and innocent, I was the first to touch her.

Had to stop there, this was my first time perving like that since becoming an adult. It was amazing, I couldn't stop shaking.

Definitely will try more next visit
