Based on the first few images I'm inclined to believe this includes body swap/gender bender, but I haven't played the game so I can't confirm.

Edit: Alright, based on the Getchu it is indeed gender bender.

playing the game atm and so far all I can say is it's pretty much the same like the first body swap by noirsoft...only this time it's between family members instead of friends....first mc wakes up in his "neesan" body then own and "imouto" so forth depending on the choices you make

someone can confirm that the only male in the CG is the protagonist? (not important if body swapped) and not taking into account the pics where are several males

@Luke2009 173-196 are the MC having sex with classmates whilst in his cousins' bodies. 84-91 are the MC doing prostitution in his older cousin's body because they need money to fix the body swapping machine. The rest are pretty much the MC having sex with the heroines. Keep in mind that even then, the MC is the girl in most of those scenes.
