Get Big On 'em (or, 'Rumble's Tumbles in the Hay')

Rumble gets a grow-up potion and goes on his way to meet the mares of Ponyville... WITH SEXY RESULTS.

After acquiring a new, extra-strong aging serum from Flim and Flam, Rumble is overjoyed to find he's just as big as he was, and twice as horny. Now it's time to tackle that list of eligible Ponyville mares he's been lusting over since the last time he got this big...

A sequel to Growing Up Fast.
