SPRD-496 - My sister is walking around in a bikini, help!

You can enjoy seeing Nanako Mori in various swimsuits. Seeing her in a swimsuit inside the house felt surprisingly fresh. I also thought she had a really beautiful backside.

Pros: You get plenty of shots of Nanako Mori's skin spilling out of her swimsuit. Personally, I loved the bath scene. Cons: The scene where she wears a hat was unnecessary. Also, the black swimsuit at the end was a bit too plain.

The film is a string of fantasy sequences—the brother's fantasy, the teacher's fantasy, and the sister's own fantasy. It’s a lazy script that even a fool could write, but the actual scene where the sister teaches her brother is surprisingly wholesome and great. Nanako Mori was excellent as the doting sister who can't help but adore her cute brother, and the actor playing the brother—who is clearly obsessed with her body but pretends not to care and acts rebellious—really added to the atmosphere. The final scene alone makes it worth watching, but you might want to lower your expectations for the overall production quality.
