I'm going to fucking scream this game is so good. but there are things you could add, such as more animations for the masturbation and after a certain amount of edging, her slick starting to show and eventually slick running down her thighs.
another thought is for the bed element, as its implied she'll eventually be able to sleep and dream and stuff. she could have dreams of being kidnapped or just taken advantage of while streaking. you could have the option to turn certain kinks on or off for dreams, or just choose not to have dreams entirely
