Found a hentai from a few years ago back when fakku wasn't shit.
There was a girl getting fucked by a dude while her boyfriend was studying in a library. I think they were on the second floor while bf was on first floor. She was wearing black high thigh boots (see pic related). Also i think the guy was a old friend of the girls from out of town but i'm not too sure about that one.
Also I think it was part of a tankoubon.
not exactly the same, but maybe
