Well the left scene is just from the breakfast scene, when she has enough corruption you can kiss her neck and start rubbing / dryhumping her ass. She also enjoys the rub but then pushes you off without drama and acts like nothing happened (good writing btw).
The right scene... don't remember if it's exactly in the game like this. There are a lot of branches you won't find immediately because they start with dialogue options that don't have requirements or stat changes.
Example in the scene where you both run to the bath, there is a "hidden" branch where you can pin her down and dryhump her on the floor. If she wears shorts instead of panties the MC will remark that it was better if she wore less and quit the scene.
(you can repeat everything later in the sandbox part of the game)
(ice cold MC !)
