Ponytropolis II

Twilight took a few steps forward as the Succubus grinned. "You're that mare I was following..."

"Following?" Asked Twilight. "What do you..."

"That was a nice car..." Ruby said as she hopped up onto the stage. "When you were leaving, uh... Bit and, uh... Bit and something..." she said, trying to remember the name.

"Bit and Bridal?!" Twilight gasped.

"Yes!" Ruby exclaimed, pointing at Twilight. "That's it!"

Twilight quickly turned to Dash. "She saw us leave Bit and Bridal... That means she knows where we live!"

"What, that hotel?" Ruby asked with a chuckle as she squatted down, placing her hands on the edge of the stage as her fingernails began growing. "I can't wait until I find my way inside there..."

Twilight growled and looked at her. "I challenge you, demon!" She yelled, pulling her shirt off and throwing it to Dash. The cyan mare caught it, going wide-eyed at the sudden assault. "You and I are gonna have a sex battle," she said, kicking her shoes off.

Ruby tilted her head with a smirk. "A sex battle?" She asked, sounding interested.

Twilight nodded and pulled her pants down, kicking them aside. "First one to cum loses."

"And, what are the stakes?"

The purple mare undid her bra and tossed it to Dash, who caught it, having to take a quick step forward to do so. "I win, you have to become my pet. If you win, we let you go."

Ruby smiled evilly as her eyes began to glow red. "Mmm-mmm..." she said, leaning forward as she slowly shook her head. "If I win... I kill you..."

Twilight stopped moving and gulped. "Shit..." She then looked back at Dash, then eyed her gun. Looking back at the Succubus, she realized this was the only way. "Fine. Deal..." she said, pulling her panties down. She then turned towards Dash and raised a finger. Putting the panties around her finger, she pulled back and sling-shot it into Dash's face. The mare let out a light pant as Twi turned back to the Succubus, her cock growing.

"Ooo..." Ruby cooed, climbing down the side of the stage before crawling across the floor to Twilight. "A mare with a nice, juicy cock..." she said, lifting her head up to smell the mare's balls. "Such a strong scent you have... I can smell the juices of others on here... How many mares have you fucked with this thing?" She asked, running a finger up to the tip.

"Six," said Twilight. "Well, one I did it in the mouth..." she said, making Chrysalis look away as she remember the orgy. "...and the other was a dragon, so..."

"A dragon?" Asked Ruby, running her nose up the cock, smelling it. "Mmm... So, that's what that smell is..." She then held Twilight's waist and ran her tongue up the mare's body, licking up between her tits to her mouth. "You think that makes you powerful enough to face me?" She asked, licking her lips.

Twilight grabbed the Succubus' hips. "We shall see..." she said, pulling her hips back and then ramming her cock into the red mare's pussy. Ruby didn't even flinch. She simply licked her lips.

"Mmm... Such a big cock... I can feel it pressing into my womb..."

Twi growled and began moving he hips back and forth, fucking the mare as she panted and gasped, feeling the warmth of the demon's pussy. "S-So warm... S-So good..."

"What'd you expect?" Asked Ruby as Twi felt her legs begin to weaken.

The Succubus smirked and gave a thrust with her hips, knocking Twilight onto her butt as Ruby dropped with her. Letting out a grunt as she hit the floor, Twilight looked into the demon's eyes before Ruby wrapped her arms around her.

"You can't beat a Succubus when it comes to sex..." Ruby cooed with a smile as she rode Twilight's huge rod.

Chrysalis and Dash watched as the Changeling eyed Dash. "Shouldn't we do something?"

Dash looked at her, Twilight's panties still in her face. "Twilight said we should wait... She knows what she's doing."

Chrysalis sighed and crossed her arms. "Fine..."

Cloudchaser kissed her sister on the forehead, trying to calm her. "It's okay... The purple mare is taking care of her..."

"Yeah..." Candy agreed, gently rubbing Flitter's arm. "Everything'll be okay, sweetie..."

Twilight arched her back as she laid on her back, moaning in pleasure. "Oh, this feels so good!"

Ruby stated to look annoyed as she kept riding Twilight. "Why haven't you cum yet?"

Twi giggled. "Maybe you're... not as good as you think..."

Ruby growled and sped up as she gripped Twilight's breasts. "Something's wrong here..."

"No, nothing's wrong..." Twilight said with a smile, biting her lip. "Mmm... Keep going..."

Ruby glared at her before pulling off. She then gripped the cock and began stroking it as she licked the tip, making the unicorn moan out in pleasure.

"One thing's for sure..." Twi moaned. "You are good... Just not good enough..."

"Oh, I'll make you cum eventually!" Ruby snapped.

"Or you could give up and be my pet..." Twi said with a smile as she sat up. "Think of how fun that'll be..." She then quickly reached out and grabbed Ruby's crotch, rubbing her wet lips. "Are you getting close?"

Ruby growled and rammed her mouth down Twilight's shaft. Twi let out a moan and a gasp when she felt her entire cock slide into the mare's throat.

"How the fuck..." Twi gasped, shocked the mare was able to take it all.

Ruby then began massaging it by vibrating her throat, making Twilight moan out loudly.

"How is she holding out?" Asked Chrysalis. "I probably would've had a couple orgasms by now..."

Dash thought for a moment before slowly pulling Twi's panties off her face, smiling as she realized.

Ruby sucked for a bit longer before pulling off and poking the dick. "What the hell?!" She growled. "Why haven't you..." she said, trailing off. She then leaned in and rubbed her cheek against the rod, sniffing it and closing her eyes. "Wait... This feels different..." she said, feeling a different kind of lust coming from the cock. "This isn't real..." she said, pulling away and glaring at Twilight. "You tricked me..."

The unicorn chuckled nervously. "Oops..."

Ruby growled before pulling her hand back. She then rammed it underneath Twilight's balls and into her pussy, making Twi gasp loudly.

"F-Fuck!" Twilight moaned out, trying to grip the floor.

"This is real, though, isn't it?" Asked Ruby, smiling as she pumped her hand inside Twi's pussy.

"Shit..." Dash said. "Twilight's fucked..." she said, pulling out her gun.

As she did, Twilight squealed as she squirted all over Ruby's hand and wrist.

The Succubus grinned. "There it is..." she cooed, quickly grabbing Twilight's throat and opening her own mouth.

Her sharp teeth shimmered in the light, making Twilight whimper as she tried to get away. Chrysalis thought quickly before coming to a conclusion.

Stepping forward, she said, "Take me."

Ruby stopped suddenly, her teeth pressing to Twilight's face but not yet cutting through. She then slowly pulled away and looked at the Changeling. "What?"

"I said... Take me instead," Chrysalis repeated. Ruby tilted her head but didn't move. "Think about it," the queen said, holding her arms out in submission. "I'm a Changeling... Lust pretty much flows through my veins. Imagine how long you could feed off me before killing me..."

"Hmm..." Ruby said, clearly thinking about it. "How tempting..."

"And, I won't fight you..." Chrysalis added, not moving as she watched the Succubus.

Candy, Cloudchaser, Octavia, Rainbow Dash, and Twilight all looked at Chrysalis and then Ruby, waiting for the next step. After what seemed like an hour, the Succubus threw Twilight to the side and lunged at Chrysalis. The unicorn tumbled across the floor as Ruby quickly grabbed Chrysalis' neck and leaned in, sniffing her.

"Mmm... There's a lot of lust in you..." she cooed, sticking out her long tongue and licking the Changeling's cheek. "Mmm... And you taste good, too..." she said before wrapping her arm around the Changeling's waist and rushing passed Dash out the door.

The cyan mare gasped and spun around, taking off after them. Once she got outside, she saw Ruby climbing up the side of a nearby building before disappearing over the rooftop.

Standing there, she simply stared. "She sacrificed herself..." she said, not believing what happened. After a brief moment she gasped. "Twilight!" Rushing back inside, she saw the purple mare slowly getting to her knees. "Are you alright?" She asked, kneeling beside her.

The mare nodded. "Uh-huh... Where's Chrysalis?" She asked, rubbing her head as she looked around. "Did Ruby take her?!" She asked, gasping.

Dash nodded. "Why do you think you're s... still alive?" Dash asked as she seemed to trail off into thought. "You're still alive because of her..."

"Well, we can't let her sacrifice be in vain..." Twilight said, getting to her feet. "We have to track that thing."

Cloudchaser then spoke up. "She said her name was Ruby."

Twi looked over at her. "Ruby, huh?" She asked. "Fitting. Well, it's good to see we got here in time. No one's hurt, right?"

Cloudchaser shook her head. "No... Just scared..." she said, stroking her sister's hair.

The unicorn nodded. As she turned to leave she spotted two Vinyl records on the floor, both having blood on them. She then looked over at the DJ booth to see Vinyl sitting up. The cellist hugged her and began talking to her but Twilight couldn't hear the conversation.

"Hmm..." she muttered, turning to Dash. "Alright... Where's my clothes?"
