I’ve written about Millie before. Please see [my first post](https://www.reddit.com/r/gonewildstories/comments/7pgbeg/angry_fucking_my_ex_in_the_park_next_to_her_house/) for a description. She was an insanely sexual person. She masturbated constantly and she was into some kinky things. Besides being a little bi, she was very into rape fantasies and incest fantasies.
While she claimed to never be interested in her own family, I started teasing her about her brother, who we will call Stan. Stan was tall and handsome so naturally, being the perv that I am, I fantasized about them fucking. When I shyly told Millie about this she was immediately turned on. She said that it was hot that I would be fantasizing about her doing something so depraved. I’m pretty sure, though, that when I would talk her through these fantasies that she was actually getting off on the idea of sucking Stan’s big cock because he wouldn’t let her borrow his car. When I told her that i imagined the two of them swimming in their parents pool, fake wrestling, and her hand accidentally grabbed his dick, leading him to pull her bottoms off and start pushing his fingers inside of her in broad daylight, she slid her own hand under her pants and made herself cum in less than a minute.
One day, while we were driving to visit the college that, 1.5 years later, she would attend, she asked me to tell her a “story.” I knew that this meant that she was horny, that she wanted me to finger her while I drove, and that she wanted to hear me say some kinky shit while I did it. So, I made up a fantasy involving two of our classmates who were sisters. In a nutshell, I told her to imagine them at an age that cannot be said here, sleeping in their shared room. I told her to imagine the older one sneaking into the younger one’s bed under the pretext of cuddling. Of course, the older one starts molesting the younger one.
Millie was fucking soaked as I was describing this story. When I described the way in which the older sister snuck her hand underneath her sister’s pj tops, caressing and pinching her tiny tits, Millie loaned loud. I had three fingers inside her wet pussy. On this day, she was wearing a sundress and she had taken off her thong. She hadn’t trimmed her pussy in a while, and it was so wet that it soaked all the curly hair around it to the point that it was matted down. When i described the way in which the older sister pulled her sister’s pj bottoms off, positioned her teenage head in between her downy legs, and started licking her untouched pussy, Millie almost squirted. Imagining these sisters making each other cum for the first time had both the passenger seat of my car and the bottom of her dressed soaked with her juices. By the time I told her that the sisters were 69ing, Millie pulled off her bra and started pinching her nipples as I made her cum for what was probably the third time. She didn’t even care that her breasts were completely exposed though my untinted windows, all she cared about was these girls’ bodies on each other.
She told me later that she would fantasize about these girls by herself for years afterwords. For years afterwords I’ve regretted not pulling over and putting my face in between her legs to taste her pussy at its wettest.
