Enbo

The manga Nikuyome ~Takayanagi Ke no Hitobito~ & Erotic Heart Mother (Enbo aka Taboo Charming Mother) was written by the same author, Tsuzuru Miyabi. Both have similar pseudo-incest themes involving Housewives/Older Women. 

Plot seems similar; son trys to plan his way to get sex from his female family members. 

Incest and great artwork. Also the taboo stuff plays a huge roll in both series.  

Both series involve TABOOs between family members. Both series have great art work and character designs. The two series give off a great narrative as to what drives these situations to continue/develop. Both story's plots contain Drama & H rated elements. 

Both have good quality scenes and the females on both shows look the same. 

+ Housewife having sex with her family members (Stepson in Enbo, Cousin in Miboujin) + Female MC (Misako Amamiya & Sonomura Ayako) can't express her love to Male MC (Ak-kun & Amamiya Kazuhiko) because they still love her husband + MC get seduced by another character (Yumika & Amamiya Emiko) but his love only for Female MC 

The husband does not give the attention he wants. But a boy can give you what he does not give you, without worrying about the consequences, no matter what is wrong. Although at first hesitate and feel guilty, in the end the pleasure will make you forget everything. 

If you are into forbidden love between step-mother and son, this is just the right one for you 

Both have a stepson committing incest with their stepmom, but more importantly there is great Maledom in both, if you like one you will like the other as well.  

NTR! Husband in both series has his gorgeous wife stolen by another guy. 

Beautiful women in both series attempt to resist revealing their immoral sexual acts and end up craving for more. 

If you liked the incest in Akiba girls then YOU will LOVE the incest in Taboo Charming Mother  

The events leading up to the result of both series are not the same. 'Enbo' has a woman with a slightly higher loyalty while 'Furyou ni Hamerarete Jusei Suru Kyonyuu Okaa-san: The Animation' pushes the woman to defy all she believe in. Yes in the end, both woman fall but one has a future in mind while the other does not. 

Similar MILF/Pseudo Incest themes. 

Both crazy incest stories with moms and their step sons. 

Both OVAs: - realistic (sex toys are the maximum); - include a small hint of domination and submission; - portray a teenager making love to his older female relative due to her being neglected by her husband; - introduce the same type of woman with big breasts; - are produced by the same studio (Milky). Besides, the endings are similar. Kasumi-san is more romantic and light-hearted, though, while Taboo Charming Mother is darker. 

Similar MILF themes 

Wives seeking something more than what is provided in their life whether it's due to the lack of attention or boring family life. True love may never be the same again once the path of no return is crossed.
