Search for a manga

Well, it's a japanese manga. It's yaoi. It's multiple stories. The first story is about a mother that helps her son have sexual relation with his son-in-law (her daughter, who was married to this young man, died). One of the stories is about a guy who returned home to caught his dad with his old classmate having sex (this son bullied the old classmate, his dad said sorry, sometime later, dad and old classmate recounter and fall in love). I remember that the title of this manga is short and i think it's in english? Anyway, if someone can help me find this one, i'm thankful!
