yes, it is chapter 2, don't know if there will be chapter 3 and on or not since this is his latest work. Hope fully someone likes Sakaki Naomoto art-style enough that they translates the work.
Summary: Kanae corners the Tanizawa at school about what happened and wants to confirm that it is masturbating that causes them to swap and jacks him off. They of course switch, but then a teacher chases them off, so Kanae says she'll go home to Tanizawa's room so they can switch back. Later she tracks the MC down and they go to a love hotel where she says she wasn't able to do it at his place because his cousin came over for babysitting and kept wanting to play games. After doing it in the hotel she tells him that masturbating is forbidden from now on ... but if he absolutely must to call her first so they can do it together... MC wakes up as Kanae again and apologizes as apparently he had a night emission. The end says "I think I'll be continuing it!"
(Although given both of them cum while having sex together, wouldn't that leave them unchanged in their current bodies? But I digress...)
