I just got paddled and I was wondering how to make my bottom not red before swimming tonight. I don't want my friends to know I got spanked, lol

Suffer through it. Your bathing suit will cover it, unless you are swimming nude ! LOL

Life sucks, be glad you are not grounded.

Depends on how skimpy your bathing suit is. There really isn't anything you can do about the colouring of the skin. Sorry.
