HKW-004 I'll lend you the key to the room where M-kun is waiting. (HKW-004)

The pleasure of eating Oazuke. The sweet and kind sister who kills men, Kona Ai, and the seemingly innocent but actually sadistic girl, Misaki Mio, both of whom are genuinely fond of men and penises from the core, visit rooms where M-kun awaits them. They repeat the process of teasing thoroughly and tormenting intensely. An omnibus work featuring an intense live-action killing festival in a private room. Witness the ultimate orgasm that feels like melting, awaiting those whose entire body is made to cum non-stop.
