Seeking Games with a bitchy sister getting blackmailed/raped

[nakati]

Like I said in the title, I'm looking for games where at least 1 of the sisters behaves like a bitch to you, and ends up being blackmailed/raped.

May include drugs, mind control, sleep sex, but they are not 100% necessary

(For example of what I'm looking for, I loved "bad bobby saga", but sadly it was abandoned and there are no sex scenes with that particular sister.)

Preferably in 3d (Ren'Py, unity, etc)

Echoes of lust, dirty pool

neither of the two game mentionned above got a bitchy sister being raped.

The sister's not terribly bitchy in it, but you can do that in The Company.

I think the Bella arc in Sisterly Lust loosely fit your description. But the "bitchy" phase really only lasts as long as you want it to.

Man Of The House
The elder sis is a bitch, and the blackmail goes both ways on diffferent stages of the game. No actual rape though

Any other games since then?
