Oh, Yes! Kasshoku Bitch Hitozuma no Seiyoku Kaishou Walkthrough (Fan-translation)

My Ex Sister In Law

This is a walkthrough for the English fan-translation of “Oh, Yes! Kasshoku Bitch Hitozuma no Seiyoku Kaishou ~Ero Ero Dekiru Mama-san Volley Kai~”. Originally created by Japanese developer Appetite and translated to English by Anonymous (More info  on VNDB).

This guide is simply based on the original Japanese walkthrough by Seiya-Saiga. So all credits to them. You’ll unlock all CGs, and you’ll need only 1 save slot.


  • Choices are not translated, but in the guide below the option should be as clear as possible. There aren’t that many anyway.
  • You can save using the first menu option (S), then choose the (S) option again.
  • Loading is done in the same menu with (L)
