Rarity's Greed gets her a sexy new form

"You sure spike" says Luna.

"Yeah..she's loose in the castle, the cutie mark crusaders are warning Applejack , Rarity and Fluttershy as we speak...as for Starlight Glimmer, well I'm unsure if she escaped and Zecora was already a victim " says SPIKE.

"That means the cure can't be finished except ...maybe, Applebloom..spike go find her , she the only pony that was learning potions left not infected " replys Celestia.

"As you wish my princess " replys Spike.

Meanwhile on another floor, Zecora the zebra is casting a potion that will age any pony by ten years. For her sights is on her apprentice Applebloom.. Zecora though knows she is to young for relations of the adult pony kind, but with this potion, she can age Her desired prey to adulthood, and teach her the ways of pleasure as her batpony mate. Zecora not greedy, makes three doses, one for Applebloom, and the other two for her two friends if she desires them as well after her transformation.

Elsewhere in the castle moans Rarity as Twibat slips her magical vampiric phallus through her slick, moist pony folds.

"Mmm..your tight Rarity..mmm..take my load into you" moans Twibat as she starts thrusting into Rarity.

This continues for sevral seconds as Twibat licks her pony lips. Soon she erupts a load deep into Rarity. It's warm as it flows deep within her pony womb. Twibats penis then shrinks back into a normal cliteris as the magic spell fulfilled its act. Twibat steps off of Rarity, as She sits up. Rarity still lays but more of a siting , lounging position.

"Mm..that was fun, but I still want you to turn me Twilight...make me a sexy vampiric batpony like the" coos Rarity.

Twibat lounges next to Rarity

"Of course my sweet...it's time to join the master" replys Twibat .

Rarity smiles as Twibat leens to her furry neck, and her fangs pierce Raritys pony flesh. Rarity gasps as the fangs enter her. It's a quick pinch of pain, then it just feels pleasureable as Twibat feeds upon Raritys blood. As Twibat feeds, Rarity form starts changing. First her ears morph to be more bat like, as she grows fangs of her own. The comes her irises changing from their blue hue to a crimson hue that glows. And finally, as Twibat finishes feeding, leather bat wings sprout from het back.

"Mmm...welcome to the family Rarity " hisses Twibat, licking blood from her pony lips.
