ONSD-634 - Ruri Saijo's M-Cup Masterpiece: 8-Hour Uncensored Marathon

The humiliation aspect is limited to groping, and unfortunately, there is no female investigator. I recommend this if you're okay with that.

Ruri-chan is known for her short bob cut now, but this features a lot of footage from when she had long hair. It's got a good runtime, so it's probably great if you just want to see a lot of scenes. Personally, though, there weren't many scenes that really did it for me, so it felt a bit lackluster.

The second best-of collection where you can fully enjoy the early days of Ruri Saijo. Just like the previous one, it's packed with content.
