MDYD-528 - Stepmother Kiriko, and the forbidden line crossed with her son

*This may be a review of this series rather than this work, but I'm not impressed with the series' standard structure. The fantasy she has about her stepmother, who she views as a sexual object, is a threesome with her two friends, where she wears a leotard, plays with lotion, and then has sex, but this part is so unnatural that it's not exciting. For example, I think it would be more natural to watch a story where there is no memory of the mother, and the story goes through things like masturbating her stepmother, bathing her (with a hand job, blowjob, etc.), and finally having sex. After the opening panty-peeping and night-sex scenes, a delusional scene begins, which clearly lowers the viewer's tension. Also, I would like you to create Niio-san's mother-in-law.
