Another masterpiece from わりゅう. Hope there is more original story from him/her and a sequel to this one! *Seems like there are more original(and sequel to this one) coming after he finish his commissions, great.
Pretty straightforward story. The heroine is a single mom, abandoned by her high school boyfriend and later by her own parents. She spent most of her adult life overworking herself and ignoring her own needs just to raise her daughter. Things were fine until her daughter brought her boyfriend home one day. Fearing she will end up a single mother just like her, she decided to protect her and take care of her boyfriend's sexual needs. As you'd expect, she totally lost against the dick and ended up becoming the boyfriend's bitch.
The author said he has some ideas for a sequel, but he also mentioned the he has some other projects he wants to do. He might release a side story on his fanbox.
