SVDVD-263 - Shame! Secretly attack amateur girls with boyfriends using machine vibes! 3

This is the work that introduced me to the 'machine vibe' genre. There are many scenes of clothed penetration within the everyday setting of a magic mirror, and the multi-person play makes it very exciting. In the sister edition, the scene with the hairy beauty being penetrated while her sister covers her mouth was the most arousing. It would have been even better if they did side-pull penetration without taking the panties off, though.
