Kyonyû massage: Shibirete zetchô

The massage parlor run by the Aoyama couple is bustling with local customers every day, all coming to see Nana's large breasts. One day, the couple rescues an elderly woman named Megumi, who has collapsed at their front door. The next morning, Megumi has vanished, leaving behind two envelopes: one containing cash and one with a "Do Not Open" sign.
