Sharing the Castle with Starlight Glimmer

Spike and Twilight both looked at each other, their bodies still shaking from another blow and boobjob. Three mornings ago, Starlight declared they should share her. Yet this was as far as they could go with the other in the room. Both felt so uncomfortable going full fuck on her while sibling watched or even worse, while the other attempted a hole of their own.

Starlight stared back up at them, waiting avidly for things to go next level. She didn't the cum baths but craved their penetrations. She wanted both inside her. She needed to know how it would feel for both to rip her holes wide open.

"Um, Twilight, Spike..." Starlight blushed, slowly sitting up. Her fingers tracing over the cocks again. "Are we ever going to do the big event?"

"What are you talking about?" The two asked.

"You know, all three of us at once?"

Twilight and Spike shared a quick look before turning to the unicorn with intense blushes. "Starlight, are you crazy? We can't do that. It's forbidden."

"You two are not blood related, so what's the problem?" She kissed each tip to full attention.

"Starlight, you don't get it." Twilight pulled free. "Spike and I are still siblings."

"Yes, this is a taboo act for a reason." Spike the same, both of them refusing to look at each other.

Starlight giggled and crawled up, wrapping her arms around their necks. "I'm not asking you to fuck each other..." She turned back around and stole a deep kiss from one of them. "I simply want you to fuck me..." Switching to the other's lips with as much lust. "And beat my holes so damn good."

Twilight and Spike were frozen. Each of them was lost in her eyes, her words were sinking into their brains. This wasn't the same as fucking in secret and then fighting for dominance over her. If they were to agree to this, they would be entering new territory. A place where their bond would never be the same again.

"Are you really serious?" Spike asked.

"If you agree, there's no turning back." Twilight stated.

"Just let it happen!!" Starlight rolled her eyes at their lack of resolve. Grabbing Twilight, she pushed her onto the bed.

Starlight shivered back and over Twilight. Wrapping her arms around her, the unicorn took Twilight's mouth and started making out with her. Spike's jaw dropped, feeling left out until her foot tugged on his cock too. Twilight was taken back by this second kiss, but returned it in a heartbeat. Their tongues danced and their breaths mixed.

The mare was so hot and the passion was undeniable. The alicorn couldn't stop, the desire was too great. Her cock was raging again, even with her brother standing in the same room. Her hips were grinding against Starlight's crotch, trying to gain entry into her. The unicorn moaned and lifted her hips up, offering the pussy up for the alicorn.

The moment she got the opportunity, Starlight slammed the alicorn's cock right into her pussy. Twilight groaned with joy and her body shook. the unicorn was so tight, even with Spike's constant plowing. It left Twilight wanting more and she was not going to hesitate. The princess's legs lifted off the ground and her wings spread, getting a better leverage. She wrapped her arms around the mare's back, squeezing her shoulders and bringing back the kiss.

Spike couldn't believe what was happening. His sister, one of the main six, a pillar of Equestria royalty was plowing his lover, the ex-villain of Starlight Glimmer. She was his, and his alone... right? The dragon was not going to allow her to leave him, nor would he share her. He ran over and dug his claws into Starlight's hips.

The unicorn mare quivered with utter delight. A wicked smile curved over her face as she spread her ass cheeks for him. Spike wasted no time and shoved his large draconic cock deep into her anus. The mare screamed with pleasure and her eyes rolled back. Twilight gasped and felt her cock be pressed aside. It was even tighter inside Starlight now.

Starlight's planned worked perfectly. She was now in the center of two horny creatures, and the feeling was amazing. Both of them started to fuck her, slamming their bodies in perfect sync. Twilight was just as strong and fierce, her cock was pulsing and her hips were smacking hard. Spike was so wild and powerful, his balls were swinging as his claws digging into her. Starlight was trapped between them and loving every second. She felt like the world was spinning and the only thing she could focus on was the pleasure.

The two members fucked in and out at incredible speed. Slowly pushing more of themselves inside her with each thrust. Their grunts were animalistic like this was always the norm for them. Starlight was a mess, her mind was melting and her body was on fire. She couldn't speak and her tongue was sticking out. All she could do was scream and moan at the pleasure.

Twilight didn't understand what was coming over her. She couldn't think straight and she didn't care. Her entire being was focused on the pleasure and her body was begging for more. She couldn't stop herself even with her brother plunging into the same mare. The princess just didn't care, she was lost and the only thing that mattered was the sex.

Spike was a little different. Throughout the weeks, Starlight had fully broken him down into nothing more then her fuck toy. He was heart broken when he found her satisfying his own sister, but couldn't deny the pull her lust had over him. Even with the betrayal, he still desired her and couldn't deny his needs for her body.

"Fuck me, harder!! Rip me in two!!" Starlight begged, shoving the alicorn's head into her breasts while leaning over to make out with Spike once again. Her body was quivering and churned their members for all their worth. Spike's draconic tongue went down her throat. Twilight took a big bite of her nipples and sucked hard. The unicorn could barely handle it. Her holes were squeezing them so hard.

"Twilight, Spike, please!!"

They fucked faster, their members swelling up with desire. Both of them were panting and moaning. Their hips were a blur on the bed and their hearts were racing. The heat was rising and their minds were going numb. They couldn't fight this anymore. Starlight had finally brought them together and now it was time for her prize.

"Cum in me, cum in me!!" She demanded, her pussy clamping down on Twilight and her ass squeezing Spike. They couldn't stop, the need was too great. Their balls were churning and the pressure was building.

"Starlight, no..." They both groan in unison.

"Fuck me, breed me, make me yours!"

It was too much, they couldn't handle it. Their bodies were on fire and their members were swelling to the breaking point. With a final thrust, both Twilight and Spike blew. Their hot seed filled up the mare's womb and stomach. She moaned, and her body spazzed. Her holes squeezing tight as their cum splashed against her walls.

Twilight and Spike were in a mix of horror and absolute delight. Their cocks were still spewing, and their heads were dizzy. Their bodies were shivering with disgust, but they didn't want to stop. The sensation of their tips brushing against each other as each one popped out of her holes was beyond words. They tried to fight it, but Starlight had truly done the impossible and shattered their bonds.

They thrusted again, at each other, spitting tiny bits of cum on the other's cocks. They didn't stop and kept going at a fever pitch. Pushing their cocks deep and brushing their tips together again.

"It feel so good, Spike!!" The alicorn affirmed

"Twilight, I need more." The dragon agreed.

They stood up over the bed, dragging the laughing unicorn with them. Flipping her around and wrapping her arms around Spike's stronger shoulders. Twilight lined Starlight's body above their cocks and dropped her down. Starlight screamed and changed positions. Spike beating into her pussy and Twilight taking her anus.

The mare's eyes rolled back, and her tongue fell out. This was all she ever wanted. To be sandwiched between two who could give her all the sex she craved. Spike and Twilight were not even thinking at this point. Thrusting her back and forth in the air, their cocks rubbing into each other's seeds. They couldn't stop, not even when her juices splashed on their legs.

The alicorn and dragon were not holding anything back. Hitting upward with enough force to break a normal mare. But Starlight was not a normal cunt. She had trained her body over the years. Building herself to handle the most powerful of beings and the roughest of lovers. The two were giving her the fuck of a lifetime and she wouldn't stop them.

No, she wanted more and more. Her holes were milking them, pulling their cocks deeper inside. She was lost and couldn't believe what was happening. It was almost like a dream. Their tips were beating and her holes were sucking. Their cocks were pumping so fast and the heat was rising again. While the snowstorm raged without any sign of ending, the room felt like a spa.

Starlight wrapped her arms around both of them, flipping to each mouth with every thrust and taking them both at once. Her juices soaked their balls and her hips was gripping their bases. This was the most intense and erotic thing she had ever felt. Her heart was pounding, and her mind was melting. She didn't want to let go, not even for a second.

Twilight and Spike couldn't think, and they didn't want to. The feeling was incredible and they didn't want to lose the moment. They could feel the unicorn's body shiver with every thrust. Her holes were tightening, and her breath was growing shorter. Both knew what was coming, but their cocks were too sensitive and three nights trading her mouth.

Finally the string was cut, and they didn't care anymore about the other being in the room, sharing the same mare. Twilight and Spike fucked her with even greater intensity. Starlight couldn't scream anymore, her voice was lost. Her body was shaking and her eyes were closed. There was only the sound of slapping skin and the sweet aroma of their sweat.

Starlight was at her peak, her climax was ready again, and her body was tensing up. Yet they would relent, they beat her holes for all their worth and her body could only handle so much. The dragon and the princess were too far gone and their cocks were swollen and heated.

"Spike, Twilight!!" The unicorn pleaded in a whisper. Her holes clamping down hard and her juices were flowing freely. They didn't say a single word in return. Their groans were too strong. Her body was shaking and her toes were curling. She could feel it, their members were reaching the limit. Her pussy was so tight and her ass gripped. It was all too much, the unicorn pulled both of their mouths over her lips at the same time.

With a final thrust, both Spike and Twilight's cocks exploded. Their tips firing rope after rope of thick cum deep into her holes. Their seeds mixed with the previous siblings' loads like incestuous buckets inside Starlight. Starlight could feel their hot seeds splashing into her walls. Their bodies were shaking and her eyes were wide open. The sensation was beyond her wildest dreams. Her mind was melting and her body was quivering.

Twilight and Spike had to fight for the air, their climaxes were too strong, and their heads were dizzy. The heat was unbearable, but her grip was even stronger. They couldn't escape her body. Starlight's pussy and ass was still sucking, begging for more of their delicious cocks. Their seeds were dripping down and coating their bases.

After a solid ten minutes passed, the dragon and the alicorn were finally able to breathe properly. They pulled out of her and dropped her like a wasted sex toy. Starlight fell to the ground, her mouth full of saliva, her holes twitching and leaking with their incestuous seeds. Her mind was mush, and her heart was pounding. She couldn't believe what had happened but knew it was far from over. Seeing their erections still casting shadows over, she rolled around and spread her legs again.

"More, please... more." She begged in a daze.

Twilight and Spike looked at each other with the same wicked smiles. They couldn't fight it anymore, their bonds were severed, and their cocks were still stiff. Leaning own, they joined her on the floor. It didn't matter at this point which hole they took. Heck, they could even share a few holes at the same time. The snowstorm raged, the winds blowing and the temperatures dropping. None of this was a problem for the trio, their bodies were burning with sexual desire and the only way to keep warm was to fuck the night away.

Starlight cried out and her entire body tensed with multiple orgasms. Their ball sacks were clashing against each other with each fuck as if they were fighting over who would fill her first. The two ponies didn't say anything, their minds too focused on the sex. She leered at their scrunching faces and their grunts, knowing that her plan had truly succeeded. Spike and Twilight were no longer siblings, but two whores willing to commit to her every desire. And there was so much she wanted to try out.

Truthfully this was never some random thirst of the moment. She had been planning this since she first arrived at the Castle of friendship. The alicorn and dragon thought she had truly reformed and wished to be a better pony. That was all a lie. She came here to twist them under her command. She couldn't convince them in the village with her intellect, so trapped in this place surrounded by a snowstorm of her own making she would win them over with her body.

And the results were exactly what she expected. Both of them were far too horny and pent up from their years of sexual frustration living together. The presence of a hot and sexy mare like her was the break in the dam. Now the two were truly addicted to her power. They were her sex slaves and once the storm was ending she would conquer this pitiful town of Ponyville and soon all of Equestria!!

So declared with the final gasps of her latest orgasm. Twilight and Spike gave their final thrusts of utter defeat, filling both her holes to the brim. Starlight threw her head back and screamed one final time as her stomach expanded with the loads of semen. She had won, the princess and dragon were under her command, and they were the first of many. Her victory was only silenced as they pulled out of her and painted her body white.
