i think it will be unrealistic sophia being naked all the time because i don't see her ever being comfortable to be commando under her clothing until aiden task comes along and even then it's a stretch for me to see her go down the sluttiest route like that. The game started with her box full of lingerie and underwear falling and it'll end with someone slipping it off onto the floor to have messy sex.
i understand your last point about being disappointed on the idea of this updates peak being Sophia naked, however, looking at the direction of the past updates; she released Dylan's cum onto herself, Sophia did make Ellie cum by eating her pussy and Vicky did allow her to stroke Deshawn, also let Vicky finish Deshawn in her hands.
i see this update as being unrealistic but if enough riskiness, filthiness and willingness out of lustfulness has happened since last night till so far afternoon (last few updates timing) then surely enough this update isn't going to end with Sophia being naked on front them. there's a lot more to expect.
