I'd question the reason given because all my three friends are hot and they know it. Like if you want to show me some nudes don't lie to me as a set up.

No one who knows me would actually select me for this because of the amount of times I've said everyone looks dumb in nudes. It's impossible to look "good", because it's an incredibly silly thing to participate in imo. The situation is an absurd one. So either be at peace with the silliness of it and embrace what it looks like afterward, which is gonna be SILLY, or just don't take any.
