I'm trying to find a specific hentai manga. I remember it was about a thin blonde who works in an office and one day two young boys who are, like, her cousins or a friend's cousins arrive and they proceed to fuck for like 100 pages. I remember the boys are hyper sexual brothers and even touch each other and crossdress. The cover of the manga was solid blue with the blonde on the front and a solid vertical yellow (or black?) line on it.
i think maybe one of the brothers was a crossdresser
