Sharing to you again one of the most beautiful & classic mother-son incest story. For me, one of the most (if not the greatest) great hentai/manga/doujin story and art of all time. Simple yet very effective to captures the hearts of its readers.
Enjoy!
None so far if I'm not mistaken. But the ending of this is somehow similar to that. They live as a typical family but no father figure. The son serve as an elder brother to her daughter/sister, while he is also a son and serve as a partner to his mom.
Many pushes the author to create a continuation of this wonderful story. Myself included. We hope one day the author hear us.
