it is choice based action to involve John, simply put; dont put drugX inside his beer. If you put DrugX+sleeping pills into John's beer based on gentle/rough value Janice will fuck him. Oh and by based on gentle/rough value i mean she fucks him alright but you can tweak the scenes like getting double penetration.As I'm just starting from 0.22 again, I'd like to confirm that there are no scenes where Janice fucks John.
Specifically, steps 378 - 381 and 398 - 399 from the walkthrough seem like they involve John somehow and I'd like to avoid them if possible. (I like to be the only one for the girls. Selfish, I know.)
