Spike laid a bowl on the floor at the foot of Sweetie’s and his bed. In it were more than enough gems to make a diamond dog punch out his own mother in order to get them. Rubies, emeralds, sapphires, topazes, amethysts, garnets, aquamarines, and a selection of every mare’s best friend: diamonds.

Sweetie Belle looked up at her husband and fluttered her eyes saccharinely. “You spoil me,” she said as she reached into the bowl and plucked out an amethyst absentmindedly. She continued to look at Spike until the jewel hovered in front of her mouth. She crossed her eyes to look at the gem. “What’s it like?”

“Ever chew a set of pop rocks?” Spike asked in reply.

“Hmmmm...” Sweetie Belle’s lips curved downward slightly as she contemplated the response. She opened her mouth and deposited the precious stone on her tongue. She closed her mouth, and then waited. After a few seconds of absolutely nothing happening Spike chuckled at Sweetie Belle.

“Didn’t your mom ever tell you to chew your food?”

The pastel-finned dragon positioned the stone between her teeth and pressed lightly with her jaw. As she increased the pressure she could sense the small fractures that began to web their way across the surface of the stone. When she gave one final squeeze the gem shattered in her mouth and bathed her mouth in the magical energies held within. The taste of grape suffused her mouth as she worked the fragments around to chew down the larger chunks.

When she at last swallowed Sweetie Belle stuck out her tongue. “That answer your question?” she inquired playfully. The purple dragon reached over to the bowl and plucked out a sapphire. He waved it in front of his wife’s tongue and grinned.

“Betcha can’t eat this using just your tongue!” he cooed. Sweetie Belle’s tongue quivered around to continue pointing at the gem as it was waved before her. Spike eventually stopped moving to let the gemstone lie in front of Sweetie’s tongue. Focusing on her reformed muscle, the white dragon stretched out until its point was well past the gem. She then curled it around the gem until it formed a loose lasso. She then carefully tightened the coil until Spike was certain she had a firm grip. It was then that Spike let go of the gem and his wife was left to support the weight herself. Her tongue drooped slightly as she brought the gem into her mouth and chomped on it.

Sweetie Belle smiled before lifting a jewel and waving it about Spike’s snout. Spike’s tongue snaked around the gemstone as he reached into the bowl himself and waved a large ruby in front of his wife’s mouth. The two fed each other in that manner for several minutes until all the crystalline minerals were gone. The dragoness reached over to her husband’s chin and slowly trailed her claw down to his belly.

Spike looked up at her and smiled. “Feel like going to bed after that?”

Sweetie Belle’s claw continue downwards until she stroked Spike’s sheath. Many layers of scales went to protecting a male dragon’s most precious asset, besides his hoard. She withdrew the claw and leaped onto the bed. She turned around and sat looking at her husband as he clambered into bed as well. He stepped over to her and closed his eyes as he brought his lips to hers.

Sweetie Belle parted her lips and granted Spike’s tongue entry as she penetrated his mouth with her own serpentine taster. The two tongues met and immediately started coiling around each other almost by reflex. Spike’s tried to wrap around Sweetie’s in a playful test of wills, but the white dragon’s tongue slipped out and tried to subdue her husband’s own whip-like appendage. Striking and wrapping, sliding and coiling and wrestling: the two dragons continued this proverbial battle of the sexes for minutes until they finally withdrew.

They were looking fondly into each other's eyes when Sweetie Belle blinked as she felt the fin along her neck raise. Spike wordlessly reached around her neck and ran the back of his paw over the semi-translucent stretch of skin. When his index plucked at a spine like a harp string a pleasured jolt ran down the length of his dragoness. As Spike’s fingers continued to agitate Sweetie’s reptilian frill she could feel a warmth building up inside of her.

“Mmmmm, hah! Uuunhh...” Sweetie’s eyes fluttered as Spike reached the last of her neck spines. She looked down herself to see a few drips had leaked out of her in the anticipation. Her gaze then turned to her husband to see that he was at full mast. The white dragon looked at the purple and grinned. “Any time I want to turn you on I just have to make those noises you like.”

Spike reached over to his partner’s lips and pressed a claw to them. He stepped a little closer and wrapped his other arm around her neck, drawing her close. When they were chest-to-chest Spike coiled his tail around Sweetie Belle’s rump. By some natural instinct Sweetie Belle did the same to her husband. The two lovers resumed kissing and engaging in a romantic duel of tongues as they wrapped their arms and legs around each other.

Sweetie Belle could feel her husband’s penis poking at her belly just above her slit. She looked around and flexed her wings. She then had an idea; she stretched her wings out as a third set of limbs to wrap around Spike. The purple dragon flexed his own wings and covered Sweetie with them. To the outside observer they would have looked like a scaled ball with spines and fins coming out every so often.

Inside the heat from their collective breath made Sweetie Belle grow even more wet as she grabbed her husband’s erect member and adjusted it until it lay directly over her entrance. Sweetie gazed at her husband who was smiling with a bit of worry tinging his eyes.

“Think you’ll be able to handle it this time?” he asked.

In response Sweetie Belle grinned coyly. “I was made for this.” With that she began pressing herself against Spike’s spire as he pushed in himself. The entrance went smoothly despite his penile barbs. If anything in this new body Sweetie’s pleasure was heightened. The little spikes on Spike’s spike rubbed against her insides and set off fireworks in the dragoness’ brain. “Guuuuuaaahhhhhggghhrrrr!” she exclaimed in a volume her husband was not used to.

“Good hurt?” he questioned with a lifted brow.

“No, just good,” Sweetie giggled as she guided her husband deeper inside.

Spike felt his member twitch in ecstasy as he pressed further into his love. This was leagues better than the telekinetic ministrations that his wife had perfected over months of finding some way around their problem. Now the problem could simply be gone through. As Spike scraped along the insides of his wife she cooed softly before he felt a new resistance.

Sweetie Belle swallowed and looked down at her husband. “Finally going to do it!” she said excitedly. “Now this will hurt a little bit no matter what you do, so if I yelp don’t stop.” Spike looked up at his wife and saw her eyes glistening with tears of joy. He nodded and slowly pushed against her hymen. In a few seconds he pushed through the barrier and Sweetie Belle grunted in discomfort. Spike stopped pressing as he waited for his dragoness to get through the sharp pain that had gone through her.

Sweetie waited as the sharp penetration died down to a dull aching throb that simply tightened herself against Spike’s penis. She began to move her hips back and forth against her husband and pressed her lips to his. They exchanged a deep kiss as Spike moved in time with his wife’s motions. There was no competition in this kiss: the two simply entwined their tongues and let their hot breath wash over each other’s faces.

The couple’s rhythmic grinding continued as Spike drove himself deeper into Sweetie Belle. Eventually, he was burying himself full-shaft into her with each thrust. A pleasured squeak escaped the dragoness’ mouth as the barbs roughly stroked the inside of her vagina. A warmth permeated Sweetie’s chest as she felt her toes become numb. Spike pounded into his wife with a greater fervor and soon she felt a pressure building in her nethers.

Spike approached his own climax as he opened his eyes to look into Sweetie’s, their tongues still locked. Her eyes were pleading for him to complete them. Adjusting his arms, Spike drove himself into Sweetie Belle, causing his wife to peak with him. Sweetie felt her insides become washed with Spike’s copious amounts of semen, warming up her insides as it bathed every crevice within her gully.

In the throes of ecstasy both dragon’s wings pulled back from each other as a sweltering pressure built in their chests. Before either of them could know what was going on they let out a deluge of fire into each other’s still locked mouths. It wasn’t a warming feeling, but tingling like chewing on mint. The fires of their hearts bathed each other’s mouths in an inferno concealed by their lips. When the blaze died down they finally pulled back.

“That wasn’t in any of the textbooks Twilight gave me!” Spike chuckled while Sweetie simply blinked. The two unraveled their limbs and extricated themselves from one another. The white dragon spooned up against her husband as he played with her fins.

“She’s going to be asking questions for weeks you know,” Sweetie Belle said as an amused smile spread over her long muzzle.

“Yeah, that should be entertaining.” Spike rolled his eyes as he continued twirling some of Sweetie’s dreadlocks with a claw.

“I could always distract Twilight, point out the looks Big MacIntosh gives her whenever she helps Applejack during harvest.” Sweetie Belle turned to look at her husband. He had a big grin on his face. “What?” she asked.

“If you manage that, when I teach you how to fly, we get to try doing this midair.”

Sweetie’s eyes opened wide at the prospect. “Is that even possible?”

“I’m becoming a powerful enough flyer to pull out apple trees while flying,” Spike replied. “We find a lake to do it over, I hold you--”

Spike was distracted by the feeling of his erect member pressing against Sweetie Belle’s belly.

“Or we could continue with a more... grounded approach right now,” Sweetie offered.

Spike extended a wing over her head, turning her vision a shade of purple as light shafted through his translucent wing. “Sounds wonderful.”
