A scheme to send love via the Equestrian Express by the triplets Derpy Hooves, Ditzy Do and Bright Eyes results in four ponies getting shipped to the same wrong address. Only one of them gets shipped to the wrong address on purpose.

In the headcanon for this story, Derpy, Ditzy and Bright are triplets.
Tagsplanation:
Teen for allusions to intimacy. And Chocolate.
Sex tag is for light innuendo. And Rainbow Dash's (implied) dirty, dirty mind.

Author's note: I didn't think this would be good enough to submit to the TwiDash competition... but after some cogitating, editing and minor rewriting, I think it's ready. And now that the contest is over, time for the rewrite and re-imagining. At some point.
