Vampire Love.

You were an ordinary pony living in Ponyville. You lived a quiet life. You had many friends, including Twilight Sparkle, and you were part of her close group. You also maintained good relationships with Twilight's other friends, Applejack, Rainbow Dash, Rarity, Pinkie Pie, and Fluttershy.

You spent most of your time with Fluttershy. Despite Fluttershy's conspicuous personality, she was more open with you than with anyone else. You often came to her tea parties and helped her care for her pets. Fluttershy seemed to have some affection for you, as she wasn't close to anyone else, not even her other friends.

Applejack recently had a problem: vampire bats had appeared on her farm, but they were actually fruit bats, and they had flown into the apple orchards. Applejack called all her friends, including you, and asked for help. Fluttershy suggested leaving part of the orchard for the bats, but Applejack insisted on driving them away completely, considering them pests.

Twilight decided to cast a spell to prevent the bats from eating the apples, but when Twilight cast the spell, Fluttershy was also affected and transformed. Fluttershy has transformed into a flying pony (she's grown fangs, her eyes have turned red).

When everyone learned of Fluttershy's fate and what happened to her, everyone began to think about how to cure her and return her to her former Pegasus form. You were sent to watch over Fluttershy while the others searched for a way to fix everything. That night, you cautiously entered the apple orchard and began looking around for Fluttershy, when suddenly you heard a sound from above.

Looking up, you saw Fluttershy hanging upside down from a branch, but she wasn't sleeping; apparently, you'd woken her. She looked at you with red, almost ruby-colored eyes. You saw hunger and desire in them, as if you were a juicy fruit. In the blink of an eye, Fluttershy flew up and grabbed you, wrapping her wings around you.

Fluttershy returned to the branch and perched on it, only now she was holding you with her hooves. You didn't understand why Fluttershy had grabbed you, but she didn't seem to pose a threat to you, at least not yet. It seemed that, having become a vampire, she had begun to desire you, desire you deeply.
