The clouds around Rainbow's house started turning dark while Glitter was still sitting there catching her breath. The bright blue sky went gray then almost black in a few seconds. A cold wind picked up and made the soft cloud floor shake under them.
Rainbow sat up and looked around. "What the hay is that?"
Before Glitter could answer a tall shape dropped out of the dark clouds and landed right in front of her. It was Princess Luna.
Her skin was pale blue and looked almost black in the low light. Her mane flowed like a night sky with little stars in it. She wore a thin black dress that clung to her slender body and teasingly outlined the shape of her breasts and hips.
Her eyes locked onto Glitter and stayed there.
"You," Luna said. Her voice was low. "Come with me."
She didn't wait for an answer.
Her magic wrapped around Glitter's waist and yanked her off the cloud. Rainbow yelled something but the sound got cut off as Luna and Glitter shot upward through the dark clouds. The wind roared past them. Glitter's cock swung between her legs the whole way. Luna kept glancing down at it while she flew.
They landed on a stone balcony of a big dark castle floating high above everything. The walls were black stone with blue glowing windows. Luna set Glitter down and the magic let go. The air was cold. Glitter's cock was still half hard and sticky from Rainbow.
Luna stepped close and looked down at it. "I felt what you did to the rainbow one. Your power is loud. I want it."
She turned around and pulled the thin dress up over her ass. She wasn't wearing anything under it. Her ass was full and pale blue. She bent forward and put her hands on the stone railing.
"Hurt me," she said. "Fuck me hard. Make it sting."
Glitter walked up behind her.
She grabbed Luna's ass with both hands and squeezed hard enough to leave red marks. Luna made a small sound and pushed back. Glitter lined her cock up and shoved it into Luna's pussy in one rough thrust. Luna's walls were tight and wet. She cried out and her knees bent.
"Yes," Luna gasped. "Harder. Don't be gentle."
Glitter pulled almost all the way out and slammed back in.
The sound of skin hitting skin echoed off the stone. She gripped Luna's hips and started fucking her fast and deep. Every thrust made Luna's ass jiggle. Glitter reached up and grabbed a handful of Luna's flowing hair and yanked her head back.
Luna moaned louder.
"Slap me," Luna said. "My ass. Do it."
Glitter brought her hand down hard on Luna's right cheek.
The slap was loud.
A red handprint showed up right away. Luna's pussy clenched around the cock. Glitter slapped the other cheek then the first one again. Each hit made Luna push back harder onto Glitter.
"More," Luna said. Her voice was shaky. "Choke me. I want to feel it tomorrow."
Glitter wrapped one hand around Luna's throat from behind and squeezed. Not enough to cut off all the air but enough that Luna had to work for each breath. She kept fucking her the whole time, hips pounding against Luna's ass. Luna's tits bounced under the dress. Spit ran down her chin. Her eyes were half closed and wet.
Glitter let go of her throat long enough to slap her ass three more times in a row. The skin turned darker red. Luna came with a broken moan, her whole body shaking. Her pussy squeezed and pulsed around Glitter's cock.
Glitter didn't slow down.
She kept thrusting through the orgasm until Luna's legs almost gave out.
She pulled out, spun Luna around, and pushed her down onto her knees on the cold stone. Luna looked up at her with messiest of manes and red marks on her neck. Glitter slapped her cock across Luna's face once, then pushed the tip into her mouth.
Luna opened wide and took it.
Glitter grabbed the top of ger head with both hands and fucked her throat.
Luna gagged and drooled but kept her eyes on Glitter's face the whole time. Her arms became weak and they dropped down to her sides while Glitter used her mouth and throat like a toy.
Glitter drew her Luna's head back for a moment then drove her cock deep into her throat and held it there. Then her cock began to twitch, moments later, a deep bubbling sound could be heard coming from inside Luna's stomach.
After thirty seconds Glitter slowly slid her herself out of Luna's throat as her plump lips made a popping sound when the shaft finally left its hilt. Thick ropes of cum continued pulsing out, splattering on Luna's face, lips, eyes, nose, nothing was spared.
Some dripped down onto her chest. Luna licked what she could reach and smiled.
"Again," she said. She stood up on shaky legs, turned, and bent over the railing once more. Cum still ran down her face. "My ass this time. Make it hurt."
Glitter spit on her cock and pushed her tip against Luna's asshole. She worked it in slow at first then thrust the rest of the way in one hard push. Luna screamed and gripped the railing so tight it began to break and crumble.
Glitter started fucking her ass with long deep strokes.
Every time she went all the way in, Luna made a broken sound. Glitter reached forward and grabbed both of Luna's arms while she fucked her. Luna came again almost right away, her ass clenching so hard it almost pushed the cock out.
They stayed like that for a long time. Glitter switched between Luna's ass and her pussy, slapping her, pulling her hair, choking her when she asked for it. Luna kept begging for more. By the time Glitter finally came inside her ass, Luna was covered in sweat, red handprints, and cum.
She was shaking and could barely stand
Glitter pulled out and stepped back. Cum leaked out of Luna's ass and ran down her thighs. Luna turned around slowly. Her face was flushed.
She looked at Glitter with wide eyes and a small smile.
"I have never felt anything like that," she said.
Her voice was soft now. "You will stay here tonight. And tomorrow. I want you again. I want you often."
She stepped closer and rested her hand on Glitter's cock. It twitched under her fingers.
"I think I am going to keep you," Luna said. She leaned in and kissed Glitter's neck. "Do not leave. I will not allow it."
The dark clouds stayed thick around the castle.
Luna wrapped her arms around Glitter's waist and led her inside.
