IENE-605 - Wife left tied up by her husband, I taught her real pleasure

I bought this to see bondage scenes with Mio Kayama, an actress with beautiful, fair skin and a great bust. However, the content is just her having kinky sex with a guy who has a high-heel fetish. The bondage is half-assed, and there's no sense of the actress's shame or vulnerability at all. Given Mio Kayama's acting range, it's perhaps inevitable that she's stuck in low-quality productions like this, but I feel like better writing and direction could have saved it.
