in terms of who is gonna the first one to have sex with sophia, he must be dylan, sam or aiden because they are the most important characters.
Given sophia's future sexual partner, we also can predict how the storyline would go.
1. She fucks dylan first: When a mom decides to fuck her son, she must've been very horny. So in this case, she has to wonder why sexual relationships with son's best friend and bully matters while she involved in incest. This may irritate dylan, but that will happen regardless.
2. She fucks sam first: Upon how romantic interact between sophia and sam we've seen, if she sleeps with sam then she loves him. Dylan might find out and because sophia is so repentant, she make it up for her son.
3. She fucks aiden first: I dont think she loves aiden at all but we have to admit she felt aroused by him. So i guess little by little, task by task, either she begs him to fuck her or she get raped. Regardless of the ramifications, it will lead to a situation where aiden humiliates her by letting dylan know how he had his way to his mom. And yeah, this is gonna hurt for both dylan and sam.
Btw, i wonder who play the most important role in lesbian route? That is not my cup of tea so idk. Partricia?
