Rainbow Dash and her human love Ivan have been together for a few years now. But Dash has noticed Ivan while loving her with all his heart, still can't seem to keep his eyes off the other mares with bigger rumps than hers. She gets an idea and asks an old friend to make a potion for her to drink so she can look like other mares. She then invites Ivan over for some fun.

Sex: Growth, big butt, macro, dildo, mare on human, human on mare, sitting on face, and just for fun real horse sounds.
