I don't know how to get past the first Enema girl encounter (can't penetrate yet, only have the first 2 powers). There's no way to masturbate on upper or lower body, the furthest I reach is bloating her with max enemas, at which point her "wake up" bar keeps going up constantly and there's no way to go back or lower her legs.
All I can do is rub her legs, belly or lick vagina to calm the bar, or lick anus which raises it faster. There's also "speak to her" and "look at belly" dialog options which I've exhausted. Do I just need to lick the vagina for minutes straight? Or go for risky anus licks until something happens? I don't get it.
You need to do a 69 with her.
