becoming fwb with my ex-boyfriend’s future roommate [FM]

Some background:

Hi there, I’m a nineteen year old girl who is in her first year of college. I’m average height, tan, brunette, with green eyes and although I have small boobs (B cups on a good day), I am told I have a great ass. (I would say I agree) I’m also in pretty good if not very good shape. (was a soccer player, now I just run a lot and lift some) This is also my first story and post, so sorry if it sucks lol.

So around a month ago, my boyfriend and I of three years broke up after about a year long rough patch. It had been pretty rocky for while, and we both just got to a point where we decided we were better as friends rather than boyfriend and girlfriend. This did not, however, happen before a close friend of mine signed a lease to be said ex-boyfriend’s roommate next year with two other mutual friends. This close friend of mine also happened to be someone I secretly had a developed a thing for shortly after my boyfriend and I’s relationship became very chippy. You see, this friend was everything my boyfriend couldn’t be in my eyes, laid back, fun, positive and uplifting, not to mention he is extremely tall with an adorable smile. The closer we became, and the more distant my then boyfriend and I became, the greater my attraction grew. Once I was finally out of the relationship, I immediately set my sights on fucking him. I was so happy to finally be free of the restraints of a toxic relationship and I decided I would try and be bold by suggesting to him we become friends with benefits when the time was right.
