Trickery

Sequel to "Fangs"
Twilight Sparkle moaned, squirming weakly in her bed. Nightmare Moon straddled her, kneeling on her forelegs, pressing her elbows onto Twilight’s shoulders and leering at her prey; her fangs shone brightly in the near-dark of Twilight’s bedchamber.
The fangs were about the only thing she could definitely see; everything else was hidden in shadow, except for the Nightmare’s body.
Where weak moonlight filtered through the window, it seemed to flow into Nightmare Moon’s body like mist, only to… seep out at the seams. Nightmare Moon was less a silhouette and more a luminous outline, like someone had sketched a goddess, using fireflies as the ink.
Nightmare Moon chuckled, bringing her muzzle to Twilight’s neck. “Come now, Twilight.” Twilight moaned again, louder. “I thought this is what you wanted.”
“I… You… You’re… Everyone… has become suspicious… I’m too tired during the day, never as happy as I should be…”
“Dearest Twilight,” Nightmare Moon rose to her full height, her words shocked, “are you suggesting you are not happy with the knowledge I am giving you? With our arrangement?”
“Nightmare…” Twilight whispered. “You’re… taking over… my life…”
Nightmare Moon frowned in the dark; Twilight could hear it in her voice. “Twilight Sparkle, you agreed to this: You would allow me to sleep beneath your castle; you would allow me to remain undisturbed; you would not reveal my return until we were ready to present ourselves; and you would allow me to siphon your magic once in each phase of the moon until I had replenished my reserves. In exchange, I would protect you during the night, and teach you the things I have learned. And in time…”
Nightmare Moon leaned in again, tickling Twilight’s ear with her breath. “In time, you will unlock your full potential as an alicorn. You could even challenge Celestia. Imagine: Princess Twilight Sparkle, Ruler of the Unified Equestria. You would be on equal footing with your dear sister-in-law Cadance, and your brother Prince Shining.”
Twilight began to cry, silently. “I’m so… empty… Cadance, Shining, Princess Celestia, Spike, my friends… don’t understand… I’ve changed so much, seen so much. I have so much duty, but no responsibilities. And when Tirek… he took everything… There’s this pit in my stomach… in my soul… you’re clawing into it…”
Twilight squirmed yet again, pushing Nightmare Moon’s face away from hers, and squinted. “Nightmare… you tricked me… now I see what you’re doing… You want… Luna’s place… You want me to fill your heart… like I want to fill mine…”
Nightmare Moon stiffened, but a throaty, amused, almost girlish chuckle escaped her. “And, dear Twilight, do you think I cannot see what you desire?” Her voice dropped to the merest whisper. “You. Want. What. Celestia. Has.”
Twilight moaned loudly, despair echoing through the room. “Noooo…”
“Twilight Sparkle,” Nightmare Moon said, harshly, “you are an adult. You have desires, you have responsibilities, you have vices. You are ashamed of what you desire; you are ashamed for having ‘given in to the darkness.’” Nightmare Moon rose again, her wings flashing out; Twilight covered her face, so bright were the ethereal feathers to her tired eyes.
“Twilight,” Nightmare Moon continued, less harsh but still sternly, “I will not deny that I covet the high seat of Equestria. I covet what Luna has: power, respect, fear… a sister.”
Twilight peeked through her forelegs, which widened their gap involuntarily as she saw what appeared to be a single diamond fall from the Nightmare’s head… from her eye.
A tear, made of moon-light.
“Our desires are the same, Twilight Sparkle.” Twilight felt Nightmare Moon’s weight lift, saw her moon-light form vanish into glimmering mist.
“I need you just as you need me; I said so before.” The voice came from just behind Twilight’s head; Twilight went rigid.
Can you say “no”?
I can’t…
Fangs sank into Twilight’s body just above her left shoulder, as they had four times before.
Twilight’s mind fell into oblivion.
