Scootaloo and her human colt friend... Colt... now his name sounds stupid. Anyway, Scootaloo has found a way to spice up their sex life with a Collar created by Acid Flask after the events of Celestial Growth. The collar allows the user to set a trigger word, and when it's said, the user's sex organs and body grow bigger.

Story includes: Older Scootalo, sex, mare on human, human on mare, micro on macro, and dick sandwiched by big butt cheeks.
