Forbidden relationships are the most exciting. What if it's your girlfriend's sister? She's cuter and she's coming onto you. Experience the heart-pounding thrill of secret, high-stakes sex while the girlfriend is just in the next room.




















I wonder why so many works, regardless of the label, end up feeling half-baked. It feels lacking unless they use an actress who could pass as the live-in sister, have some light intimacy, and then move on to the younger sister. In the second part, they were finally about to kiss, and then the doorbell rings... They should have at least had a quick session before the doorbell rang. Aside from the second part, the actress playing the sister makes you wonder, 'Wait, he lives with her?' The gap between the sisters is just too jarring. Please, have a round with the sister first.
I think Yua Yoshikawa was the only one who really pulled off the 'little sister' vibe well. Her firm, large breasts when she stripped were also fantastic. Satomi Suzuki isn't bad, but as a little sister? I don't know. Her breasts are great, but... she feels more like an 'older sister' type to me!
It's a bit underwhelming because there's no real interaction with her. Everything happens in the apartment, but if she's supposed to be the younger sister, couldn't they have done it somewhere else, like a place they visited together?
The woman playing the live-in partner is just terrible... The first and third characters aren't exactly great either, but the second woman is so noisy that it kind of killed my desire to watch the subsequent scene with the younger sister. Even if the character is supposed to be hysterical, couldn't they have toned it down a bit?
This used to be my favorite label, but... 1. Yua Yoshikawa, the low-quality fake breasts are a huge turn-off. 2. Hinata Tachibana, she's been incredibly cute since 'Can-Colle' and looks great in tight jeans. Her acting has improved too. 3. Satomi Suzuki, haven't seen her in about two years; she's aged into a 'gyaru' style but still has the figure. Overall, the production is sloppy and there's zero excitement. The transition from guilt is poorly handled. I wish they'd put more effort into the emotional shifts. If it weren't for Hinata, this would be a one-star review.
