Tales of Corruption

Luna enter the Canterlot throne room. Celestia had called for her. Upon entering, Luna noticed a small overturned tray on the floor. Some food has been spilled, along with some green condiment she doesn't recognize. "Please excuse the mess, there was no time." Celestia suddenly appeared in front of Luna, her eyes dropping and she is barely able to hold herself up. A yawn escapes her. "My Sister," Luna asks, "why have you called me? It is nearly time to raise the moon." Celestia closes her eyes for a moment, though she smiles when she does. "Sister?" Luna asks again. One of Celestia's hooves traces the side of her mouth, where a small bit of green is still visible. Slowly, she licks it off, eyes still closed. Her shoulders sag, and Celestia falls. Luna quickly jumps forward, catching her sister. She feels her sister's head rub against her, and a hot breath against her coat. "I'm so tired," Celestia breathes into Luna's ear. "And sleep feels so good." Celestia gently bites Luna's ear. "S-sister!" Luna steps back, easing Celestia off herself. Luna raises her head to speak, but it is cut off by Celestia's mouth suddenly in hers. There is a strange taste before Luna's mouth goes numb, and heat spreads through her body. Her hind legs shudder and collapse as Celestia forces herself forward. From the corner of her eye, Luna sees a green flash. The light hurts, and Luna closes her eyes.

Instantly, she feels compleatly relaxed, the heat spreading faster before. Her front legs go, compleatly collapsing and breaking off the kiss. "Well, well. It seems you love your sister after all." With difficulty, Luna forces her eyes open, and the pleasure fades, just a little. She sees the Changeling Queen, Chrysalis, standing over Celestia's prone form. Chrysalis had one hoof raised, covered in the green goo. Celestia's head lifts just enough to give the outstretched hoof a lick. "Well, Luna?" Chrysalis asks, "Aren't you tired?" "N-no," Luna breathes, staring at Celestia. "Sister, no, please. We know what it's like to feel this temptation, to wish only to give in, but you mustn't!" One of Celestia's eyes flickers open, a tingle of green light within them. Chrysalis laughs. "How cute, the night princess doesn't want to sleep, but we both know." Chrysalis moves, faster than Luna's tired eyes can track. Luna feels breath in her ear again. "You gave in once. You already know how good it feels, don't you? And you're already so, so tired." I am," Luna starts, "I am stronger now." :But you've tasted it once." Chrysalis purrs, gently, tracing a hoof along Luna's muzzle. Sweet smelling goo sticks to her fur, she tastes it with every inhale. Every blink sends a spark through her, and closing her eyes feels so good. Just a little rest. "What's one more time?" Chrysalis asks, "Go ahead, I can promise there will be no more...nightmares." "I am tired," Luna says finally. "Good girl," Chrysalis says, allowing a lick of her hoof, "and now," Chrysalis looks out a window, to the rising moon. A slight green tinge shadows it, washing the light over Equestria. "Sweet dreams."
