It's a lesbian story where the main character's brother comes home with his girlfriend and the main character and the brother's girlfriend start fucking after some mutual masturbation

Is this a story you have seen somewhere already on the site, or one you hope to see written?

OK that was a bad summary. Brother comes home from college for the summer and brings his new girlfriend with him. One night as the sister is masturbating in her room, she hears brother and his girlfriend having sex in his room. Thier rooms are connected by a bathroom. After her bother climaxes, she hears the bathroom door open and the girlfriend tries to sneak through her room to get out. Sister surprises her and they talk and she finds out that the girlfriend has never orgasmed while having sex with brother so she has always had to relieve herself after. Sister somehow gets girlfriend to masturbate with her and after they finish, girlfriend goes back to sleep with brother. This happens as couple times until they start getting each other off and things are starting to get awkward around the house. Finally girlfriend breaks up with brother and leaves the house. She stays at a hotel for a night and sister visits. I don't remember much after that. This story might have been in a series format.
