SDMS-725 - SOD Executive Series: The girls with mutated, oversized pleasure organs.

Surprisingly good. The director and Tsubomi-chan appear in the commentary mode, and I think watching it while listening to that is the best way to enjoy it. Her personality shines through, and the commentary makes it clear that she's genuinely enjoying herself, which is a huge turn-on. Listening to Tsubomi-chan's comments during the intense scenes with the actor will definitely get you hard.
