Switched and Hitched

(Late April Fools request, originally a one shot so may get a follow up chapter in the future) What if a mistake on Ash's part led to two unique demons coming to Ooo and helping setting up a romance long forgotten about... plus more when Finn's student gets involved and a zombified Ash as well... get ready for laughs and lemons in Switched and Hitched... one to possible two shot.
