Hello

I'm looking for an extremely long fic in which Dean, working as a barista or something similar, is attracted to Castiel who is often in the coffee shop reading. Dean thinks he's a teacher, but one day when Cas leaves his book behind Dean heads to the college to return it (with his telephone number inside) and discovers he's actually a student.

He then refuses to do anything about the attraction due to the age difference but still befriends Cas, who ends up moving in with him & Sam, & taking over their living room as they don't have a spare bedroom which doesn't impress Lisa, who Dean has started dating. Eventually Dean & Lisa break up but Dean is a bit wary of relationships so he doesn't ask Cas out.

However there is a movie night, which ends up being a porn night, which ends in Dean offering to 'help out' Cas (who I think fell somewhere on the asexual spectrum) & they end up in a friends with benefits arrangement for quite some time as they explore Cas's sexuality.

Eventally, of course, there is an admittance of feelings and they officially get together. There was also a sequel written from Cas's pov which may have been a wip.

I'm all googled out trying to look for this, can anyone help me out?
