The yellow scientist left the room with the succubus in it and was greeted by a purple colt scientist.

"Tell Stone Shard I'll sign off as her permanent guardian," the yellow colt said.

"You sure?" asked the purple colt. "You sure she won't tear into you like the other one?"

"I'm sure, Tide. Just give me the form."

Tide smiled. "As you wish, Sunny... Just don't come crawling back to me when she rips off your legs."

Sunny chuckled. "I'm sure it won't come to that..."

The purple colt rolled his eyes before walking away. Sunny then eyed the door of the room where the succubus was.

Trixie and Lightning Dust looked around the cell as Trixie let out a yell. "Ah! Trixie can't take this anymore! I need out!" she yelled, holding her head.

Lightning jumped at the sudden outburst before holding her by the shoulders. "Relax, Trix... They're letting us out, remember? It won't be long now."

"But, it's taking forever!" Trixie complained.

Lightning then forced her on her back and climbed atop her. "You need to CHILL!" she yelled, making Trixie shut up instantly. "If you freak out and assault whoever comes to let us out then we're never getting out of here. Now, I don't know about you... but, I'd rather become a team again than waste my life away in here!"

The blue unicorn hesitated before sighing. "You're right... Trixie apologizes..."

Lightning then leaned in close to Trixie's ear. "And, you can talk normal when you're with me..."

Trixie smiled. "I'm sorry."

"Better..." Lightning cooed, before leaning in and kissing the mare.

Trixie shuddered and wrapped her arms around the mare's neck and her legs around Lightning's legs.

"Whoo! A show!" Gilda cheered, standing up and gripping the bars as she watched.

Amanté rolled her eyes as she lay on her back in her cell. Sunset Shimmer looked over at them and smiled, reaching between her legs. Gilda also began to rub herself and gripped her right breast with a moan.

Sunset Shimmer looked to her left at Amanté's cell. "Hey," she said, crawling over to the bars and standing up. "Amanté?" The black mare looked over at her and saw Shimmer spreading her dripping pussy. "Come on... Help me out here..."

Amanté hesitated before sighing. "Alright..." she said as she sat up and crawled over to the bars.

Once there, she pressed her face to the bars and stuck out her tongue, licking away at the mare's slit and making her moan.

Meanwhile, Gilda had dropped to her knees and was pushing a talon into her own slit, moaning loudly.

"Oh, that's it..." she moaned, still watching Trixie and Dust.

Suddenly, Applejack walked in and stopped, letting out a chuckle. "Holy shit, ya'll."

Every mare and griff immediately stopped and looked over at her. "Oh, don't let me stop ya. Keep goin'..."

"Which one of us is next?" asked Trixie, holding Lightning's face against her crotch.

"Amanté," Applejack replied, walking over to the black mare's cell.

"Oh, come on!" Trixie groaned.

"You seem to be passing the time pretty well..." AJ said with a chuckle as she pulled the key from her pocket and unlocked the cell. "Besides, ah was told ya'd be next, anyways, so..."

Trixie smiled and pushed Lightning's face deeper into her slit out of happiness. Applejack eyed her with a chuckle before opening Amanté's cell.

"Ready?" asked AJ.

The black mare gave one last suck on Shimmer's slit before pulling away and standing up. "Of course," she said, walking to the orange mare.

Sunny opened the door to his quarters at the lab and entered, shutting the door behind him. When he turned the light on he was tackled to the wall by the succubus. Her hands and feet were pressed to the wall, trapping the colt as she opened her mouth, revealing monstrously sharp teeth. After about a second, however, she closed her mouth and looked him over.

"Oh... You..." she said, before leaping at the ceiling and squatting down on it.

The colt's heart rate returned to normal as he looked up at her. "I see your powers are developing. You can walk on walls and ceilings now..."

"Fun..." the nude succubus replied as she crawled around a little.

"So, it's now official," Sunny said with a smile. "I'm your guardian now. Meaning I will be the one who takes care of you and keeps you under control."

The succubus hesitated as she stared at him. "I like you," she said again.

Sunny chuckled. "Which is why I took this assignment," he said, heading to the bathroom door. "Now, try not to cause any trouble while I take a shower, okay?" he said as he opened the door.

The succubus looked at him before quickly and silently crawling across the ceiling towards the bathroom door. As the colt entered the succubus crawled in over the top edge of the doorway and onto the ceiling of the bathroom. Sunny then shut the door with a sigh, not knowing he was being watched as he began to undress.

He took off his lab coat and hung it on the door before taking off his white shirt, tossing it onto the toilet. He then slipped out of his pants and boxers, tossing them with his shirt. The succubus eyed the colt's junk with hungry eyes as Sunny stretched. He then went to the shower and turned the water on. When it began to steam he stepped in with a happy sigh, closing the curtain.

The succubus then dropped to the floor and crawled over to the shower, watching the silhouette of the colt against the curtain. Once she saw him turn to face the wall she slipped inside and then slowly stood behind him. Sunny didn't even notice her as he let the water wash over his face. After a brief moment he turned around and opened his eyes, letting out a yell of surprise as he found himself looking into the crimson eyes of the pseudo-demon.

"Oh... damn..." he sighed, quickly realizing who it was. "What are you doing in here?" The succubus tilted her head before leaning in and sniffing his shoulder, her D-cups pressing to his chest. "I thought I told you to wait in the bedroom..."

The mare then looked him in the eyes. "You no like me?"

Sunny started to say something but sighed. "That's not it all... I just..." He then looked her over and sighed. "All right... You can stay in here..."

The mare smiled lightly and looked down at the colt's hard junk, quickly getting to her knees.

"Oh, boy..." the colt said, watching her.

She looked over the twitching meat, leaning in slowly before opening her mouth, revealing her sharp teeth. The colt gasped and grabbed her shoulders, kneeling down.

"No no no..." he said before chuckling. "That's not how to do it..."

The mare closed her mouth and tilted her head. "Then... How?" she asked.

"Um..." the colt said, trying to think how to explain this. "Oh..." he said. "May I see your hand?" he asked, reaching out and gently taking her wrist. The succubus looked at what he was doing before looking him in the eyes again. Her lack of resistance told him it was okay, so he held her hand near his face. "This is how you do it..." he said, before wrapping his lips around the mare's thumb.

He then bobbed his head up and down, pretending the thumb was a cock. He then pulled away and smiled. "See? No teeth. Just lips and tongue," he explained. "And notice how it's still attached and unharmed? That's most important. Understand?"

The mare looked at her thumb and then at the colt's dick, nodding. "Yes."

Sunny hesitated before standing. "Alright... Same goes for these," he said, patting his ball sack. "No teeth. Just lips and tongue."

"Okay," the mare replied, leaning in again and opening her mouth.

This time her teeth stayed normal as she wrapped her lips around his shaft, pushing down so her lips touched his crotch as his cock slipped down her throat.

"H-Holy fuck..." Sunny moaned, feeling the succubus deepthroat his cock with ease.

She then began to quickly bob her head as she slurped and gulped, making lewd noises as it sounded like she was devouring his cock. Sunny pressed his back to the wall and moaned out, his legs feeling weak.

"H-Hold on, I... I gotta sit down..." he said as the succubus kept sucking.

He then slid down the wall into a seated position, his cock slipping out of the mare's mouth. She tilted her head and licked her lips, looking down at the cock. After hesitating in thought she smiled, crawling into the colt's lap. Without hesitation, she raised her hips and slammed them down on his crotch. The colt moaned as he felt his rod enter her pussy and held her waist.

"You don't... waste time... do you?" he said with a chuckle as he began to thrust into her.

The mare moaned out and began to quickly move her hips, riding the colt somewhat roughly as she placed her hands on his shoulders. After a bit more riding, the mare let out a moan as demon wings shot out of her back and a tail grew above her butt. Sunny went wide-eyed as he looked at her new form but didn't stop fucking her.

"Damn... I guess you can make those come and go when you please..." he said in awe, wishing he had his clipboard.

The mare kept riding him a little while longer before the colt grunted, firing his load deep into her pussy. The succubus let out a loud moan as she felt the energy course through her, sighing happily before looking the colt in the eyes.

"I like you..." she repeated.

Sunny smiled and rubbed her butt. "I like you, too."

"I won't eat you."

The colt chuckled. "That's good to hear."

"We have sex often?"

Sunny smiled. "If you want." The succubus rested her head on the colt's shoulder. It wasn't out of exhaustion but more for comfort. "We will need a name for you, though..."

"A name?"

"Yes... How about..." Sunny thought aloud. "Um... Cinder?" The mare stayed quiet as the colt shook his head. "No, you're not hot... I-I mean you're not fire based," the colt said quickly. "No fire powers. So Cinder wouldn't really work... Um..." He then looked over her body. "You're Red... What about... Ruby?"

The mare lifted her head at this to look him the eyes. "Ruby?"

"Yeah, do you like that?"

The succubus hesitated in thought before smiling. "Ruby..."

"Ruby, it is, then," the colt said with a chuckle.

The mare then rested her head on his shoulder again, kissing him on the neck. "Master..." she cooed, pressing her chest into his as she kissed his neck.

Sunny let out a silent gasp but did nothing except wrap his arms around her, holding her close.
