My Roommate's Brother

Alexia Rivers had moved into an apartment with her very best friend when they both turned twenty-two. The idea had been brought up multiple times as a joke until one day became their reality. People didn't like the idea of a man and woman living together without being married to each other, but her man wasn't attracted to women in the slightest. They've never fought or had any other form of emotion towards each other besides pure bliss. Will all of that change when she has a one night stand with his brother? Especially when his brother forms an obsession over Alexia and wants to be near her all the time.
