Pumpkin Spice Latte

The main quartet (Mordecai, CJ, Rigby and Eileen) are ready for a night of Halloween partying, but the weather turns their plans around. Instead, they spend the night in the house, drinking pumpkin spice lattes and warming up... with more than just blankets. Mainly Rigleen [Rigby x Eileen] with side-couple, Cloudycai [Mordecai x CJ]! Oneshot! Happy (belated) Halloween, folk! R&R?
