Miyuki

She's an elf, a vampire, and a sorceress. A failed spell has left her cursed. The curse transforms her into a doll, and she ends up in my room. She needs my sperm to become an elf again. She speaks to me telepathically, and I can hear her voice. She uses manipulative tricks to make me ejaculate inside her quickly, but at the same time, she enjoys it. Although she doesn't want to become addicted, she's happy when she reappears in my room as a doll.
