Looking for story: Girl comes home on college break to find old fuckbuddy still around and cheats on her boyfriend

[theadmiralspawn]

I think the conceit was it was her brother's friend who was kind of an asshole and her boyfriend is passed out on the couch while they fuck and then eventually move to the bedroom. It was the second or so time she'd done that but idk if it was a chapter 2 in a sense
