Corrupting the Crystal Heart

Spike had never quite openly admitted this before but he was a hell of a boob guy, he loved the feeling of tit flesh against his cock. Plus there was always something of a power move walking around with big titted sluts on each arm. As such he had learned he really liked titjobs these days, and the only thing he liked more was a double titjobs. As such having the two busty bisexual wives pressed their tits against his cock was a feeling right out of heaven, and he soon found himself unleashing his load like a geyser and painting the two pairs of tits white.

The two mares were squealing with joy, frantic hands eagerly took great big handfuls of the sticky substance into each other their hands like it was sweet honey. Both took long sniffs of the substance, and delighted in the musky scent that tickled their nostrils.

“You should lick my cum off each other,” Spike ordered the two. Upon his order they were quick to dive onto each other. Gleaming was first, wrapping her sapphire lips around Cadence’s neck and slowly rolling her tongue against her cum coated skin.

“Wow I guess every pony loves the taste of my cum right?” Spike asked, and the two could only nod dumbly as their **** tongues scooped up any drop of his semen that they could find. He was brought again to a full erection. Soon they had licked each other completely clean, not that this caused them to stop.

“Hey your Master is sitting here unattended. Don’t you have any sexy ideas Cadence?” He asked, waving his hands to indicate himself. The Princess of Lust seemed to have been stricken with an idea. She rushed forward and took her Master’s hands into hers with an evil glint in her eyes.

“I do indeed Master, follow me,” she said dragging him away without bothering to get dressed. They ran naked throughout the Crystal Palace with Gleaming Shield trailing behind, at least until they approached the room where the Crystal Heart resided. It was at this moment that Spike was quite glad that the Crystal Heart had been shielded off since word of the conspiracy met Shining Armour. After all they didn’t want anyone to do anything to such an important artefact.

But of course the real threat to the Crystal Heart did not come from any external threat at all, but rather an internal threat from the pink alicorn who eyed the Heart with a savage glee.

“Did I ever tell you two about my special connection with the Crystal Heart?” She asked tapping her fingers across said object. It seemed to shake to her touch, as if it could sense the growing threat. “It’s in my Cutie Mark after all, you know that the Crystal Heart can lift the spirits of the Crystal Empire, but I believe it can do so much more than just that if I try.”

Her eyes darted to her Master’s eyes with an evil smirk on her face as she jutted her ass out and swayed it in little circles towards him, “it’s dependent of my emotions, thoughts and… desires.”

She emphasised that last word with a long drawn out groan. “And if I were to feel those emotions, thoughts and desires were focused on being dominated by a certain dragon when I’m connected to the Crystal Heart…”

“Then I imagine that would be an idea that spreads throughout the Crystal Empire, though it could create unintended consequences,” Gleaming Shield pointed out, but Spike was busy smiling like a savage.

“Only pleasant ones right?” He asked, getting an approving grin from Cadence for his prudent use of his power.

“Let’s find out Master,” Cadence asked, shaking her ever so invitingly, lustful sweat drenching her fur and creating an intoxicating smell for the dragon.

“Gleaming make sure that we’re not interrupted,” Spike ordered her, sparing her only the briefest of glare’s, so fixated as he was on Cadence’s ass.

“Understood Master, I’ll gather the guards. Maybe get started of giving the stallions new out of the way jobs, and perhaps introduce the girls to our new dress code.” Gleaming Shield said, giving the pair two thumbs up. "Just wish I had updated my armour."

That was a problem easily fixed Spike thought. "Don't you have it already altered exactly as you wanted? Aren't you wearing it right now?"

"Of course I am Master," Gleaming Shield said now wearing her new armour. Strangely it seemed despite her new life as a massive slut, and now as his sex ****, the act of going out in public in armour fit only for a stripper still embarrassed her if the faint pink blush on her face was any indication. But Spike looked past that blush to see how splendidly perverse her outfit was. With leggings that acted more like stockings, a battle skirt that would leave her exposed in a gentle breeze and a chest plate that served only to push up her breasts rather than protect them.

"Irresistible Gleaming dear, but hurry along now. If I am to corrupt the heart then I'll require some inspiration Master," Cadence said with a voice bordering on song. Spike could smell the cum leaking out of her pussy and evaporating into steam. The Princess in heat was truly reaching a boiling point, it was fortunate dragons could bear any heat.

A tongue rolled across Spike's lips as he approached the Princess, as Gleaming Shield left the room. He'd been growing more confident since Rarity had convinced him to embrace his role as Master of the harem, and that confidence had become dominance. Cadence was waiting in apt attention as her Master approached, placing her fingers on the Crystal Heart, her cutie mark lit up just as the Crystal Heart did as well. The tips of her fingers glowed a rosy purple along with her horn.

Spike took his place behind Cadence, and the alicorn was eager to shove her ass into his waist begging him to take her right now, but Spike instead decided to reach forward and take a breast in each hand. Rubbing his hands from her chest to her nipple and feeling her soft, burning skin melt with his hands. Gasps and moans escaped the lips of the Princess and were channeled into the nature of the Crystal Heart.

"Please... please stop stalling Master. This unworthy **** requires your cock," she begged, her voice little more than feeble gasps at his touch.

"Tell me," Spike ordered, his voice now deceptively calm.

"Tell you what Master?" She begged, **** eyes looking back at him.

"Why you want to be my ****."

"Why?" She gasped in disbelief, they both knew the real reason was because of the Root of Honesty. But she knew that's not what her Master wanted, he wanted her to tell him what appealed to her now. What the new Cadence wanted to be.

"I want to be your **** because I want to make your life perfect. I want to be there Master as you transform Equestria piece by piece into your perfect harem. I want to be in hoard because your dick is magnificent and no other stallion can compare. Least of all my old husband," she gasped, causing Spike's already savage smile to become a full on grin. He pushed his dick into into her cunt driving her face to full aheago. She was now screaming into the heavens, not caring at all who heard, in fact she was hoping that the entire Crystal Empire heard.

"I NEED TO BE YOUR SLUT SO YOU CAN ALWAYS FUCK MY HORNY CUNT! I NEED TO MAKE YOU PLEASED! I NEED RARITY TO BE BETTER THAN ME! I NEED HER TO BE YOUR DIAMOND! AND I NEED TO BE YOUR BITCH, YOUR WHORE, YOUR ****!"

With her final words she let out a scream as she orgasmed over his cock, almost losing her grip on the heart as it began to be corrupted to its core. Dark shades of a crimson red lined its outsides and it pulsed with a crimson red like magic, ready to corrupt the Empire in new and lewd ways. But the Crystal Heart didn't just lift the spirits of the Crystal Ponies, but also was meant to repel certain evils. Most especially the evil King Sombra and this corruption would affect him in a unique way.

A/N: I'll be honest this was a bit of a filler chapter, I'm stuck for ideas to do with Sombra/ Umbra and could do with some suggestions, sometimes these votes really surprise me since Sombra/ Umbra was fifth last time, you guys really like your genderswaps I see. Hopefully I can either think of something soon, or someone has a good idea I can borrow.
