My dad remarried, and my new mom, Ai-san, was my homeroom teacher in elementary school. She always treats me like a child, with overly intense physical contact, but when I'm enveloped by those big breasts, everything else doesn't matter. As a student struggling with grades, she offered to tutor me and said, 'I'll give you a reward for every correct answer.' The rewards get more intense with each correct answer, a classic setup that's highly engaging.

Ai-san's super-sized breasts are stunning, and the film makes full use of them with ample breast-focused scenes. There are even two well-executed oral scenes with her erotic mouth, no skimping on details, which left me thoroughly satisfied. The interactions are great, highlighting her fair skin and tempting large breasts. For someone like me who loves seductive and doting scenarios, this was the work I'd been waiting for. A man needs a big-breasted sister he can snuggle up to and who'll accept him in bed.

However, most of the filming is in dimly lit environments, which doesn't do justice to Ai-san's body—a bit of a shame. Even when the curtains are opened at the end for some outside light, it remains quite dark. The pigeon-chested breasts might make it a bit hard to get excited for some, but overall, it's well done. The plot twist where achieving the goal leads to grades dropping again is rare in other works, and the ensuing punishment and teasing add nice spice. If I had to suggest something, a finale where she gets pregnant with the husband's or son's child and it's left ambiguous could have been interesting.

Overall, it's an enjoyable piece in the tutor genre, crafted to stir up those feelings of wanting to be pampered. I watched it myself and could relate to the son's obsessed, greedy demeanor. While the darkness might bother some, it adds depth to the situation.
