Well, it was written by someone who at other times writes yaoi...
And it sure reads like it! Woah there, gals.
Actually, it's pretty rare that I see someone openly writing sex scenes for both flavors of gay, so in that regards the author has my serious respect (Additionally, looks like they right a bunch of straight smut too). A bit of everything; that's sort of refreshing, even if a lot of it is a bit too much for me.
