[FM] [MF] friends or backstabbing? Vanilla story if my cheating gf.

Was my bday and me and my girlfriend at that time threw a party. Bunch of mini games and drinks.
She invited her friends and some of my friends as well. So roughly about 6 girls and 7 guys. Two of the guys were my girlfriends’s ex. One dated her during middle school. And one dated her sophomore year of highschool til senior year. The girls they were pretty, besides two cause female always need someone to make them look better. Single guys besides me, taken girls besides 1ugly and one pretty. What my gf didn’t know was one of them was lily(the name i used on the girl from my last story) her brother didn’t come cause he had work and no pto left. She is dating now in a serious relationship and has one kid now. Beginning of the year, so it’s still cold out and party started at 4 but didn’t kick off until people started drinking more.

Quick story, [MF] [MFF] the sisters

I had a thing for my friend’s younger sister. She is a year younger, and also she has a sister a year younger than her.
I went over to my friend’s house, to hang out and chill. Most of the reason is to see her. She was pretty cute, and her younger sis (also cuter) but i was into the older one because we had history. Me and her used to talk years before during middle school year. Met her at an open casket funeral.
Continuing with the story, i was hanging out with my friend, then he had to go do some errans for his mom. I told him if its just 10-30 minutes, I’ll wait for him at his house. So i did and he left. I took the chance and went and hung out with the sisters. We sat and watched movies. They were both whispering to each other and giggling like kids. I then started small talks with her and the younger sister.
One thing led to another, i sat next to her and holding her. We all shared a blanket as it was pretty cold during the winter. On my side, i was holding her hand and touching her thigh. On the other end, the younger sister was playing footsy with me. (Couch was pretty long) 3-5minutes in the movie, i was kissing the older sister as the younger one was watching. I slowly move my leg so that my feet was aligned with the sis’s pussy and slowly rub it with my feet. Toasty feet, cause it was warm.
Not long my friend returned, and i told them i gtg. Me and my friend hung out more then he had to go to work(3rd shift) so i left and went home. Later that night the older sister (ill use lily so it’ll be easier)(angel for the younger) so lily messaged me that her pussy is craving some dick. Now if you read my tale of my virginity, i had a two bounce wonder. This one came close. I quickly went over.

First theater head. [MF]

So there is this one girl i was obsessing over during the summer of 2015, Petite asian with big tits and ass.

I stumble on her facebook because i have mutual friends with her. So i decided to shoot my shots. She had a bf, i knew him alittle. So i messaged her and she said they broke up a while ago but i never knew.
We kept talking for a few days until i had the courage to ask her about sex. Even though i wanted to ask her sooner but didn’t want her to know my intentions or what not. She told me, her ex and her fucked every day for 1 year, then regularly on the weekend for the last 3 years. She admit she had cheated on him a few times with her other ex who came back and messaged her. Of course they never had sex before the most recent one. She mentioned one time her bf(at the time of event) was in the next room when she gave his friend heads and swallow. Then making out with him here and there that night.
So a freak she was. But a sexy one.
