■肉体交換～妻の体で奉仕する男～
Nikutai Koukan~Tsuma no karada de houshisuru otoko ~

It's a body swap. The textless cgs start around pg 56 or so?

Description: An unemployed manager who lost his job switches bodies with his slutty wife who was supporting him through prostitution, after she coldly says "I wish you knew what I have to go through."

When they switch bodies she "trains" him, and in the end he decides he wants to live as a girl (and learns to speak in female speech) 'cas the pleasure feels so good. And he's told "You're already such a slut." His wife enters a company again, and they both adjust so well to their bodies they wouldn't want to go back even if they knew how.

(There isn't a full description yet because I have barely read it. In fact, I posted it by accident!)

Translation to English would still be great.... oh well!
