Another girl getting a picture of them doing something together in a hallway and then confronting them in private about it- then using that opening to break down and ask him if it's weird that she masturbates with a vibe and about her insecurities about masturbation in general. This of course leads to Kazoe asking what the hell a vibe is, but fortunately (?!) the girl brought it with her. After the obligatory "What the hell were you thinking?!" facepalm, Hanazono then feels obliged to explain that the loanword "vibe" refers specifically to oscillating dildos in Japan, while what she has is a "rotor" i.e. an egg, and then when he demonstrates to Kazoe what it does she immediately decides it's just like an "electric massager" which forces him to correct her because in Japan that term specifically refers to things things like the Hitachi wand. The guy is a walking TMI about fetish stuff, but he means well. ^_^;
