When talking about Sam's concert or some of the other arcs of the novel, we can fantasize endlessly and end up falling far short of L&P's intentions.
In my opinion, the only juicy event that we can predict with a high probability of coincidence with L&P is the plot of Sofia and Zach when she next goes to his spa salon.
First, she plans to sunbathe naked.
Secondly, she saw Zach naked and she is very interested in how big his penis can be in an excited state.
Third, they would be alone there.
These and many other small and important factors and events that have already happened and will still happen by the time they meet at the spa, suggest that Sofia can take the initiative to see Zach's penis in an excited state.
I don't know what game day Sofia is going to go to the spa, but she probably wants to know how far Zach can go? Depending on when exactly that happens, that's how much Sophia will allow Zach.
It is not possible to talk about other arcs today, something more specific than about Zack.
What are your thoughts on this?
Just please seriously, drop the speculation.
That's easy: Alyssa and Ellie. Sophia has already shown she is willing to go further with the women than with the boys.
Now that "Coach Sophia" has been dropped, Alyssa is back on to meet up with Sophia on playable day 17 at Alyssa's apartment. Which is the "ignition point" of their relationship, quoting L&P. They will be there alone, except for Antonio. Alyssa has already got Sophia wet
twice, and once on the brink of orgasm she Sophia was riding Antonio. One of her students not being there, and Alyssa not being family may be enough to get Sophia relaxed enough to push her over the edge.
Sophia is already comfortable being naked with Ellie, in Sophia's favourite place to masturbate, being caught several times, both by Dylan and Ellie. Ellie's is the route that
requires Sophia and Liam not to be having sex, increasing the chances of Sophia actually being horny during the event. Ellie is also one of the few (like Alyssa) that can get Sophia wet. All Ellie would need would be to convince Sophia that it'd be okay if she masturbated in front of her, same as how Ellie did in the shower last update. There is also the yet to be had conversations about how "intimate shaving" because of how much Sophia enjoys oral.
