Appearing in the 4th series is ... Ayano Kato, a beautiful constricted butt! She is on good terms with Hibihata Combi, but it seems embarrassing to have her anal carefully observed. Otsuki's long tongue penetrates her anus, and Hatano expands her anal. Only in the distribution limited edition, the making video of 3 people who are too close with "Kato & Otsuki blaming Hatano for captive squid lesbians" is recorded! !
