Identify Looking for name of game

[industrialpotato]

Looking for a 3D Japanese game:
- Has themes of: highschool, bondage, rape, incest
- Has some visual novel elements
- 3D sex scene controlled like Honey Select
- Protag can choose to participate or not in the sex scene
- Involves 2 highschool girls: a blonde (antag) and brunette (protag's sister)
- Something about licking feet?

Vaguely recalling the back story:
The blond antag is the queen/leader of a school clique or something like that, and the sister is bullied into being their underling.
