After Donkey and Shrek had fucked so hard, they felt awkward. Shrek awkwardly went home to his beloved wife, Fiona.
Shrek walked into the door.
Fiona kissed him and welcomed him home.
Shrek got a boner from that. Fiona noticed and blushed a bit, "Oh, Shrek. Would you like me to take care of that for you?" Fiona said with a wink. Shrek declined, because he had just gotten satisfied by Donkey.
Fiona was suprised, and a bit raged. Shrek never declined her sexual invitations. Fiona ignored Shrek for the rest of the day, and then approached Shrek later that day, "Shrek, do I not please you in bed anymore?"
Shrek sighed, "No, my darling. It's just, I wouldnt have lasted long because.."
Fiona knew what happened right there, "You cheated, Shrek?"
Shrek sighed.
Fiona was heartbroken.
