Yeah, I'm pretty sure it won't be any of "our" girls, too. I'm just asking for 100% confirmation. This game even has some funny moments making fun of cucks and NTR like in this update.

So we're pretty safe. And, yes, I agree. Jake's ex-girlfriend should get some love from the MC.
No, there is no incest of any kind. There are
threesomes between the MC and a mother (Vicky) and her daughter, (Jenna, tha main girl) but between them they do not interact sexually. And all bisexual/lesbian content is totally optional, you are not forced to watch this content, don't worry.
