Her sister is physically weak and cannot have children. So, her sister asks her younger sister, Hina, to have sex with her husband to conceive a child. Hina agrees for the sake of her beloved sister, but contrary to Hina's pure intentions, her brother-in-law becomes obsessed with her young body and loses his mind. As his demands escalate, Hina's body and mind begin to change...




















The only downside is that the older sister and her husband are a bit too old, but casting Sugiura Bokki to interact with Hina-chan was clearly a calculated move to boost the sense of taboo, so I'll let it slide. Regardless, it lived up to expectations with some very erotic scenes. It’s a wild world where such a cute girl gets so passionate with a guy like Bokki. The sister’s resentful expression was a nice touch, too.
It was great seeing Sasaki Hina pull her skirt down slightly to expose her belly button, and then having it licked so wetly.
The age gap between the sister and the parents feels way too forced. If she's a surrogate, how old would the parents even be by the time the kid grows up? It's also hard to buy the premise that there's no guilt involved in the sexual acts... First, the scene in the daughter's room: penetration while fully clothed, followed by a massive amount of fluid. The blowjob in the changing room and the hallway masturbation leading into sex were good, but it cuts off with the sister watching from afar. The second half features deep penetration in a sailor uniform. The daughter seems to really enjoy it, and there's a solid creampie. Even here, the sister's shadow is on the sliding door. Finally, the daughter with a growing belly and the brother-in-law, with the sister watching through the crack in the door... It's terrifying.
[Pros] The lead actress is cute and her facial expressions are great. The actor also did a good job portraying a husband who is considerate of his wife. [Cons] The actress playing the older sister is a terrible actor. The sister and her husband look too old; they just look like parents. [Verdict] It felt a bit much to jump straight into the sex scene from the start, but the progression of their growing intimacy was handled well. Don't expect too much, but it's above average for this genre.
