The Chin.Po, eh? Great naming sense. Also, what a great mum she has! But damn, quite the generation they live in. Electric dildos and portable onaholes controlled with a remote... Hmm, he mentions visual stimulation but the moment she offers to help, he instantly assume she means sex. He is certainly quite savvy about his hentai situations! Pft, also, great ending. The father wanting to 'try' it as well, with the punchline being 'as a massager'...Amazing.
"It's a bit smaller than the one mom's got installed at home... " (page 7, panel 1)
Apparently, Moriyama and her mom shared the same big wall-cock! That's so typical of Tatsuro's subtle little curve balls. They make the reader stop and think: "Wait... what... ?"
Tatsuro loves to throw the reader a curve ball, but it's always a playful, gentle curve ball (and often there's more than one, as in this chapter). His tales are in a class by themselves--- odd, quirky, and cheeky---like the sort of thing Thorne Smith might have written, if he had applied himself to eromanga.
