I suspect how it’s gonna work is, after enough horny dreams about the MC, Emma will confess it to either Suzi or Lucy, both of whom will be repelled at first… then come round to the idea when they realize just how super horny much in love Emma is.
But what’d be more fun is if Emma climbs on top of his cock while he’s sleeping, Charlotte walks in on them, and kicks him out for a bit. During which time Emma will beg her to come round. But what’ll ultimately sway her will be some rapey guy whom the MC conveniently happens to intercept and castrate, preferably by crushing his balls with his bare hand.
Then it’s all, “Oh, MC, you’re the best; you can have my daughter but only if I get to join in,” and every player’s head explodes with joy. Well, it’s more likely the other head explodes.
