Naughty sister

I never did anything with my sis but I did with my older chubby girl cousin when I was like eleven and she was thirteen on three separate occasions when I was visiting her. We'd go off together on horseback while the rest of the family was busy making lunch or just talking.
We went to the barn and once into the nearby woods near the creek. She taught me how to "French kiss" and we had sex. I didn't ejaculate yet but I did dry cum inside of both her vagina and once inside her asshole.

When my little sister was like around six she'd be on her tummy with one of the pillows from the sofa tucked under her chin to watch tv.
I remember that we were watching Personal Best on HBO. From the sofa I noticed that she had tucked the pillow under her hips and was slowly pushing her ips against the pillow as the explicit part of the movie was playing.
I didn't say a thing because my own hand had slipped into my panties seeking my own orgasm as well LOL 🤭

I had just turned twelve and I remember our parents not being in the house with us when my then fourteen year old sister actually letting me do anal sex to her. She initiated everything by getting me to go into the walk in closet in her room and do "practice" kissing before she turned around for me. It was awkward as hell at first but I got like crazy horny and did it to her. It was over pretty quickly and it got even way more awkward afterwards.
We only did it that one time, she'd crush any of my hints to go for more when I was horny. She'd tell me to go jerk off (which I would do thinking of her) Over time we never talked about it and we actually grew apart. It's actually been like three or four years since I have even heard from her, now that we are adults.

Yup, girls are as naughty as boys.

Even worse than boys usually.

Great sister
