Rainbow bat returns to Ponyville

The transformation complete, Cozy Glow smirked as her new minions rose to their hooves, their bodies now sleek and bat-winged like hers. "Excellent," she purred, her voice dripping with dark magic. "Now, let's have some real fun." She pushed Bon Bon down onto the grass, spreading her hind legs wide. Lyra watched with lust-filled eyes as Cozy lowered her head and ran her long tongue along Bon Bon's wet slit. Bon Bon moaned loudly, arching her back as Cozy's tongue explored her depths, lapping up her juices with hungry, deliberate strokes. "Yes... more..." Bon Bon begged, her hooves gripping the grass. Cozy complied, burying her muzzle deeper, her tongue flicking against Bon Bon's clit, circling it before plunging back inside. Lyra moved closer, pressing her own dripping cunt against Bon Bon's face, and the three of them became a tangle of pleasure and corruption, their moans echoing through the now-darkened park. Cozy's eyes glowed with crimson fire as she tasted her new thrall, savoring the submission and lust she had awakened.

Cozy's tongue slid deeper into Bon Bon's wet folds, her muzzle slick with juices as she lapped and sucked with increasing fervor. Bon Bon's moans grew louder, her body trembling as waves of pleasure crashed through her corrupted form. "That's it," Cozy purred against her flesh, her voice muffled but commanding. "Let yourself go. Give in to the darkness." Lyra, her own body burning with need, lowered her head and began licking Bon Bon's clit while Cozy's tongue worked inside her. Bon Bon screamed, her back arching off the grass as the dual stimulation sent her over the edge. Her juices flowed freely, coating both of their muzzles as she convulsed in orgasm. But Cozy wasn't finished. She pulled away, her crimson eyes gleaming with hunger. "Your turn," she said to Lyra, pushing her onto her back. Spreading Lyra's hind legs wide, Cozy lowered her head again, her tongue tracing a slow, deliberate path from Lyra's belly down to her wet slit. Lyra gasped as Cozy's tongue parted her folds, dipping inside before withdrawing to circle her clit. "Please... more..." Lyra begged, her hooves tangling in Cozy's mane. Cozy smiled against her flesh, then plunged her tongue deep inside Lyra, fucking her with it while her nose pressed against Lyra's clit. Bon Bon crawled closer, her own body still humming with pleasure, and began licking Cozy's exposed cunt from behind. Cozy moaned against Lyra's pussy, the sensation sending jolts of pleasure through her own body. For a moment, she allowed herself to enjoy it, her tongue working faster inside Lyra as Bon Bon's tongue explored her depths. Lyra came with a scream, her body shuddering as Cozy's tongue pressed deep inside her, drinking her release. Cozy pulled away, her chin dripping with Lyra's juices, and turned to face Bon Bon. "Now, my dear," she said, her voice low and seductive, "let me show you what true pleasure feels like." She mounted Bon Bon from behind, her bat-like wings spreading wide as she pressed her cunt against Bon Bon's flank. Her tongue snaked out, licking Bon Bon's ear as she whispered, "You're mine now. All three of us are going to have so much fun together." Her hips began to move, grinding against Bon Bon's wet pussy, their bodies sliding together in a rhythm of corruption and desire.

Lyra moved behind Cozy, her tongue finding Cozy's clit, lapping at it while Cozy fucked Bon Bon. The three of them moved together, a tangle of moans and slick flesh, their bodies singing with dark magic. Cozy felt her own orgasm building, her body trembling as Lyra's tongue worked her clit and her own hips ground against Bon Bon. "Yes... yes..." she hissed, her eyes blazing crimson. "Together... now..." They came as one, their bodies convulsing in a shared climax that left them breathless and trembling on the grass. Cozy collapsed onto Bon Bon's back, her wings folding as she caught her breath. "That's just the beginning," she murmured, her voice thick with promise. "There's so much more pleasure to spread through Ponyville."

As the three corrupted ponies lay tangled together, their bodies still humming with dark pleasure, a sudden gust of wind swept through the park. Cozy Glow's ears perked up, her crimson eyes narrowing as she sensed a familiar presence. A cyan blur streaked across the night sky, landing silently on the grass before them. Rainbow Dash stood there, but she was transformed. Her cyan coat gleamed with an otherworldly sheen, her rainbow mane now streaked with deep purple and black. Bat-like wings, larger and more powerful than Cozy's, folded against her flanks. Her eyes glowed with the same crimson fire, but there was something else—a mark on her shoulder, a dark sigil that pulsed with power. "Cozy Glow," Rainbow Dash said, her voice a low, seductive growl. "My master sensed a new corruption spreading through Ponyville. I see you've been busy." Cozy rose to her hooves, unashamed of her slick, body. "Rainbow Dash. Or should I say, Rainbow Bat Dash?" She smirked, her tongue tracing her lips. " master must be powerful indeed to have turned the Element of Loyalty into a creature of the night." Rainbow Dash stepped closer, her hips swaying with an unnatural grace. "He is. And he wants to see you. He's been watching your work with interest." She looked down at Lyra and Bon Bon, who were still recovering, their bodies glistening. "But first, I think we should have some fun." Cozy's eyes lit up. "I couldn't agree more." Rainbow Dash moved to stand before Cozy, her muzzle inches away. "Show me what you've learned," she whispered, her breath hot against Cozy's lips. "I want to see if you're worthy of our master's attention." Without waiting for a response, Rainbow Dash pressed her body against Cozy's, her tongue snaking out to lick along Cozy's jawline. Cozy moaned, her body responding instantly to the touch of a more powerful predator. Lyra and Bon Bon watched, their eyes full with lust, as the two bat ponies began to circle each other, their tails swishing, their wings half-spread. Rainbow Dash pushed Cozy onto the grass, spreading her hind legs wide. "Let me taste what you've been feeding on," she murmured, lowering her head. Her tongue, longer and more dexterous than before, traced a path down Cozy's belly, dipping into her navel before sliding between her wet folds. Cozy gasped, her back arching as Rainbow Dash's tongue explored her depths with expert precision. "Yes... yes..." Cozy moaned, her hooves gripping Rainbow Dash's mane. "More..." Rainbow Dash complied, her tongue plunging deep inside Cozy while her muzzle pressed against Cozy's clit. She lapped and sucked, drinking in Cozy's juices as if they were the finest nectar. Cozy's body trembled, her orgasm building rapidly under the assault of Rainbow Dash's skilled tongue. But Rainbow Dash pulled away just before Cozy could climax, leaving her quivering on the grass. "Not yet," she said, her voice dripping with dominance. "You'll come when I allow it." Cozy whimpered, her body aching with need. "Please..." Rainbow Dash smiled, her fangs glinting. "First, tell me everything you know about what ponies you have corruptied and turn, just these 2 or is their more." As Cozy began to speak, her voice breathless and desperate, Rainbow Dash's hoof traced lazy circles around Cozy's wet entrance, teasing her without giving her the release she craved. Lyra and Bon Bon watched, their own bodies burning with arousal, waiting for their turn with the powerful bat pony who had just arrived.

Cozy's breath hitched as Rainbow Dash's hoof continued its torturous circles around her entrance. "Only these two... for now," she gasped, her hips bucking involuntarily. "But I have plans for more. Rarity... Twilight... all of Ponyville will taste the masters corruption." Rainbow Dash's eyes gleamed with approval. "Good. Our master will be pleased with your ambition." She lowered her head, her tongue flicking out to tease Cozy's clit. "But ambition alone isn't enough. You need to prove your submission." Cozy whimpered, her body trembling with need. "I'll do anything. Just please... let me come." Rainbow Dash smiled, her fangs glinting. "Then submit to me. Acknowledge me as your superior, and I'll give you the release you crave." "Never," Cozy hissed, her pride flaring despite her desperate state. "I'm the one who spreads his corruption.the first to be turned by him, not you, I bow to no one but master bloodstone" Rainbow Dash's eyes narrowed. She pulled away entirely, leaving Cozy squirming on the grass. "Then you're not ready for me." She turned to Lyra and Bon Bon. "You two. Come here." Lyra and Bon Bon scrambled forward, their bodies still slick with arousal. Rainbow Dash positioned them before her, their hindquarters presented to her muzzle. "Watch, Cozy. Watch how true submission looks." Rainbow Dash's tongue plunged into Lyra's wet folds, making the mint-green mare cry out in pleasure. At the same time, her hoof worked Bon Bon's clit, bringing both ponies to the edge within moments. "You see?" Rainbow Dash murmured between licks. "They know their place. They accept the pleasure I give them." Cozy watched, her body burning with jealousy and arousal. She hated admitting defeat, but her need was overwhelming. "Fine," she finally gasped. "You're superior. Please... let me come." Rainbow Dash paused, looking up with a satisfied smirk. "Good girl." She returned to Cozy, her tongue immediately finding her clit while two hooves slid inside her. Cozy screamed as her orgasm finally crashed over her, her body convulsing violently. Rainbow Dash drank every drop, not stopping until Cozy was limp and trembling. When Cozy finally caught her breath, Rainbow Dash was already mounting Lyra from behind, her hips pounding against the mint-green mare's flanks. Bon Bon pressed against Rainbow Dash's side, her tongue working the cyan bat pony's nipples. Cozy watched, her body still humming with aftershocks, as Rainbow Dash took both ponies with practiced ease. "You may of been turned first, but as a ex element of harmony, im his general, now Join us," Rainbow Dash commanded, her voice thick with pleasure. "There's room for one more." Cozy crawled forward, her body aching but eager. She positioned herself behind Bon Bon, her tongue finding the mare's clit while her hooves gripped Rainbow Dash's hips. The four of them moved together, a tangle of moans and slick flesh, their bodies glowing with dark magic. Rainbow Dash came first, her body shuddering as she emptied into Lyra. Lyra followed moments later, her scream muffled by Bon Bon's tail. Bon Bon came next, her juices flooding Cozy's mouth. Cozy drank greedily, her own orgasm building again. "Yes... yes..." Cozy moaned against Bon Bon's cunt. "Together..." They came as one, their bodies convulsing in a shared climax that left them all breathless on the grass. Rainbow Dash collapsed onto Lyra, her wings folding as she caught her breath. "You've proven yourself," Rainbow Dash said, her voice low and satisfied. "Our master will be pleased. Now go to him. He resides in his new castle deep within everfree forest..." She looked at the three corrupted ponies, her eyes glowing. "We three will rest And prepare." Cozy smiled, her body still humming with pleasure. "I can't wait."

Back in her library, Twilight Sparkle paced frantically, her hooves leaving deep grooves in the wooden floor. The image of Cozy Glow's transformation burned in her mind—those bat-like wings, the way she'd had Lyra and Bon Bon, enthralled or something, the raw pleasure and allure that had radiated from body. "I need to understand this," Twilight muttered, pulling books from shelves with her magic. "There has to be something in here about vampiric transformations... about dark magic that corrupts through pleasure." She spread several ancient tomes across her reading desk, their pages yellowed with age. As she scanned through texts on dark magic and corruption, a chill ran down her spine. The descriptions matched perfectly—the bat wings, the heightened senses, the insatiable hunger for both blood and pleasure. "It's an ancient curse," she whispered, her hoof tracing a passage. "Spread through intimate contact, binding the corrupted to those they fuck, their sire to be with a venomous bite. But who turned Cozy? She was just a filly..now an adult." A knock at her door made her jump. "Twilight? Are you in there?" It was Rarity's voice, concerned but steady. Twilight hurried to the door and opened it a crack. "Rarity! I was just... researching." Rarity's eyes widened as she caught sight of the open books. "Darling, you look positively frazzled. What's going on? I saw Rainbow Dash flying toward the Everfree Forest earlier, and she looked... different." Twilight's blood ran cold. "Different how?" "Her wings," Rarity said slowly. "They were... bat-like. And her eyes were glowing. I thought it might be some new costume, but now I'm not so sure." Twilight pulled Rarity inside and closed the door. "We have a problem. A serious problem. Cozy Glow has been transformed into some kind of vampire , maybe better term would be sexpire pony, and she's been corrupting others. Lyra and Bon Bon are already probly turned. And now Rainbow Dash..." "Oh my," Rarity breathed, her hooves flying to her mouth. "What do we do?" Twilight's horn glowed as she activated a protective spell around the library. "First, we secure this building. Then I need to contact Princess Celestia. If this spreads any further, all of Equestria could fall." As she spoke, a shadow passed over the library window. Both ponies looked up to see a dark figure circling above—a bat pony with Rainbow Dash's distinctive rainbow mane, her eyes gleaming with malevolent intelligence. "She's already here," Rarity whispered, her voice trembling. Twilight's horn flared brighter. "Stay close to me. Whatever happens, don't let her give you any plesaure physically, thats hoe you succumb to the corruption and eventuallyshell turn you with her fangs." The shadow landed silently on the library's roof, and a low, seductive voice echoed through the wooden walls: "Twilight... Rarity... I can feel your fear, and slight arrousel, It's delicious. Why don't you come out and play?" Twilight's heart pounded as she realized the nightmare was only beginning.
