How come they look so shocked despite they had sex too? Shouldn't they look tired?

@DiaStarkLordoftheBed my guess is the first page of them reaching for a random paper decide which girl will be the one to have sex with the guy.
and the following pages are just "what if this chick was the one who got the lucky number instead.", that would explain why it always look like they're seeing it for the first time.
