I remember reading this yaoi manga but I can't remember the title of it. All I recall is that the brother is living together with his brother-in-law because the sister, who?s the wife, had an affair and ran away with another man. One night, both guys happened to sleep together and the brother-in-law hugged the brother from behind as he mumbled the sister?s name in his sleep, so the brother just lets him hold onto him. Afterward, the brother-in-law realizes it wasn?t his wife but the brother whom he hugged. However, he still continues to hug the brother every night while pretending not to know as he rubs his erection onto the brother. One day, the brother was concerned that his underwear would get dirtied, so he took it out and I think they did the deed.

Wow I don't know it but now I want to read it too.
