SDMS-972 - Office gossip: The truth about the two most talked-about beauties

The first one seems to be an actress named Yuina Manami. Her amateur acting is decent, but the pacing is too rushed; she gives in to the erotic commands way too easily, which kills the 'amateur' vibe. The sex scenes are hot, though. The second is Komine Hinata, who is clearly the main focus. It uses the typical blackmail trope of this series, but the gap between her plain, bespectacled office-worker look and her incredibly sexy body is top-tier. The sex scenes are undeniably erotic. The office worker setting is just a bonus; I think this is a work meant purely for enjoying the sex scenes.
