Since the vanishing of the human race, ponies from all over Equestria have been living on Earth for a while now

Rainbow dash, You, and Pinkie pie were all in the woods playing. "I'm gonna get ya Pinkie!" Rainbow said while chasing Pinkie. "WEEE!!" Pinkie said while running away with you, Rainbow bumped into Pinkie and was on top of her, nuzzling her snout in Pinkie's neck.

"Rainbow!" She blushed as she kissed her cheek while Rainbow nibbled at her neck, they were a couple.
