Once he's finished cleaning up his mess remind your husband that it's important to pee after sex.
Go to the washroom but DO NOT wipe -let his tongue do that
Seriously. (pee is sterile and safe) and he probably won't even notice -
To add a little bit of humiliation tell him BEFORE you sit on his face.
Then have him lick you to another orgasm.
and remember if he complains....-TAKE a picture!
