After a long day, Mac goes to wash himself in the public shower (do ponies use showers?). Boom is new to Ponyville. He sees Mac, and can't resist that hunky red stallion. He finds a nice spot with a good view, sits himself down, and Big Mac is none the wiser. For a little while… Mac finds Boom, and the fun ensues.
