you can already edge her. she can get to a point where she’s so sex hungry, that she’ll just force herself on you (not rape because MC consents). getting her to this point is pretty simple.
First. You want her to have her full AI active, just play the story if she’s not fully sapient yet.
Second. You’ll want to edge her, this will increase her “horny stat”. you can see how close to cumming she is, by how full the omega symbol is on her tummy. letting her cum will decrease her “horny stat”.
Third. Lots of head pats. this will increase her “affection level”. DO NOT DENY HER WHEN SHE ASKS FOR SEX, this will decrease her “affection level”.
Fourth. Sleep. She only starts the scene when you go to sleep, AND both her “affection level” and “horny level” are high enough.
TL;DR: edge her, give head pats, don’t let her cum, don’t deny sex, sleep often.
