Leave it there and she leaves without a skirt or panties? I think something is wrong here. I understand that it is a game that contains ntr, but theoretically the options that lead to that are advised. And I can assure you that I did not choose them. And Julia casually walks off in Preston's direction without even panties. The scene was cut because the dev's computer couldn't anymore? surely, but the continuation seems to offer little doubt
The important part is that as far as I know you cannot
not cheat on Julia. I'd suspect some form of regret over suggesting to check the place out and being mad at MC would be a motive but MC literally doesn't care regardless of player choice either. On the non-three-letter-word route, Julia only has eyes for you regardless, right? Whatever else happens Julia knows she's just one of his orbiters (regardless of the love and affection route(s) being a thing), not his only romantic partner and that'll have to be factored in for the rest of the story. Makes sense since I alread thought that was going to be this kind of MC since the opening scenes with Lana.
I'm mentally preparing for scenarios wherein barely nubile smol tiddy goth gf Lilly thinks MC is such a great guy for working at a spa and lobbying for her to get a job there, and ending up on the same massage table as Lana did, while having similar frisky incidents with the latter and others. Just happens that I'm too awesome and incidents happen, brah.
