Finally back with this one. Will be semi regular, can't promise when it will update but can promise it will be updating again.

Chapter 10: The Diamond Lust

Arriving at the bakery, Spike surveyed the shop. Spotting many ponies milling about and socializing as part of their daily routine. Upon spotting Pinkie, the bump Spike gave her clearly showing on her normally thin frame, he approached. Seeing Spike, Pinkie let Mrs. Cake know she would be absent for a moment and left upstairs to her room with Spike following.

Once inside with the two seated at her couch. "So, how's the quest going Spike?" She asked, giving the drake a soda and cupcake.

“It’s going...quite well.” He said honestly, taking a bite of the delicious confectionary. “Just...need to finish the last bit of it with...the most important mare of all.”

"Finally gonna go after Rarity then, huh?" Pinkie asked, a sly smirk as she rubbed her belly lump. "Surprised you waited this long honestly, though having experience under your belt is best before going after your dream mare."

“I have to be the best I can be to please her.” Spike said honestly. “I just...hope I can accomplish it…” The dragon said quietly, taking a quick drink of his soda.

"Oh, you've come a long way since then, Spikey. Granted, it actually hasn't been that long, you've learned a lot about the art of making love. Well, how are you planning on approaching her?"

“No idea…” Spike sighed out. “I could ask her out on a date, try and wine and dine her...but that sounds too cheesy at this point…”

Pinkie chuckled. "Well that would be right out of her romance novels. Though you'd best first charm her before anything. Given she's known you since you were little, gonna have to use some charisma to show her you aren’t little anymore."

“And I have all you lovely mares to prove I’ve got charisma in spades.” Spike smiled.

"Heh, to be fair though Lyra and I more or less gave you freebies." Spike huffed at that. "Look, we both know how you get around her. All tongue tied and blushing red like a ruby. You need practice…and maybe some help for things to go perfect."

“Alright…” Spike said, curious where she was going. “I’m gonna need some help…”

"I can help you practice with some lines and possibilities for your conversations with her, but also I'll need to make a pit stop at Zecora's for some…extra help."

“What would we need at Zecora’s?” Spike raised an eyebrow.

"Only a little guarantee Rarity’s gonna carry her own little baby half dragon~" Pinkie teased. "A simple fertility potion."

“Well...would certainly be interesting.” Spike said honestly. “And...well making sure she has my kid now would be...even better.”

"I can pop by real fast to grab one and til I get back you can try and write out several pickup lines to start off with."

“Please…” Spike nodded. “I’d rather not flounder like a fish out of water.”

"Then get to thinking. I'll be right back." Pinkie said, quickly taking leave while Spike put pen to paper and began to write out his options. He had read a few of the romance novels Rarity favored most and remembered a few lines from them.

Almost an hour later, Pinkie came back with two bottles. One was pinkish, the other a lime green. "So, how's the lines going?" Pinkie asked.

“I’m trying not to be cheesy as shit...but it’s not possible.” Spike groaned, as he handed over the two pages he’d managed to write for Pinkie to look over.

Picking them up, Pinkie browsed the various phrases. "Heh, yeah… though, this one isn't so bad. 'Shall we take a stroll and partake of the coriander?' that's not too bad."

“That was my best one too…” Spike shook his head.

"You do know that coriander is typically associated with lust right? It's a fittingly symbolic one-liner."

“Hopefully she won’t think I’m coming on too strong.” Spike said nervously. “But...well it’s worth a shot.”

"Knowing Rarity she'll get the reference, probably blush and such but be flattered nonetheless. Maybe save it as a closing line though, opening with it would be a bit too direct and strong."

“Yeah, best keep that for the right time.” Spike nodded. “And now to...think of how to get her to drink the potion.”

"Oh, leave that to me." Pinkie said with a nod. "Rarity is at the spa right now, once she's done there she always comes over here for an after spa treat. Typically she orders a muffin and mini pie but I'll give her a fruit smoothie, while she sits and talks with you~" Pinkie said. "And before she can even refuse the drink I'll be sure it's her favorite, Coconut Raspberry with a bit of lemon and salt. She can't resist those."

“Geez, you sure planned this out.” Spike said, honestly surprised at how detailed Pinkie's ruse was for a spur-of-the-moment plan.

"Yup. I spike—hehe—the smoothie with the potion. Also this one is for you." She said, giving the lime green bottle to Spike. "It's also a fertility potion but special for dragons. Zecora basically guarantee that heat or no, these two potions drunk before sex would help even an infertile pair have a baby."

“That’s amazing to hear.” Spike smiled happily, thinking that out of all the mares he’s lusted after, he really wanted to have a kid with Rarity the most.

"Yup. Honestly I'd be amazed if she only ends up with one foal. She might get twins, or more! Maybe. Zecora was explaining how the potions work but all that went a bit over my head."

“I don’t want her to get hurt because of it though.” Spike said nervously, having read up that too many foals can hurt the mother.

"I doubt she will. Hang on, maybe Zecora gave me some instructions." Pinkie said, sifting through her saddlebags. She picked up, pulling up a small folded paper. "Here we go." She said, giving it to Spike.

“Thank you.” Spike nodded as he took the piece of paper and unfolded it, curious to know what Zecora had written down.

Potion of Fertility (Female Brew)

This potion of pink will alight a mare's need, making her ready and raring to breed. Her heat will begin with no hesitation, and her eggs more easily fertilized by a male's insemination.
Beware good mare, that of this potion you do not take more than this weekly share. Too much can cause a lust unshrouded, and leave a mare with a womb quite crowded.

Potion of Fertility (Male Brew: Dragon)

For an anonymous dragon Ponyville is quite the hike, for sure this must be for Spike. Worry not, my lips are sealed. By me, your coming tryst will not be revealed. This potion will make your seed abundant, and an increased speed of your swimmers will see them meet your female's egg triumphant. With this brew's effect your testicles will refill quite rapid, loads copious and frequent will ensure her loins will not long be arid. A drink before an encounter most erotic will see your lovemaking that night abundantly episodic.

“Oh boy...Rarity is gonna have one amazing night from all this.” He said in anticipation.

"I bet. Better down it now, Spike. Takes ten minutes to kick in and lasts a whole day. I'll head down to the kitchen and get Rarity's regular order and the smoothie ready. Just hang out in the dining room until she gets there."

“Alright.” He nodded as he took the male brew and uncorked it as he downed it readily.

He savored the taste. It reminded him of lemonade but not as tangy.

Heading back downstairs, Spike sat at a table, eagerly waiting for Rarity to enter through the doors. Pinkie gave him a milkshake and sapphire donut to snack on while he waited.

As time passed Spike felt the potion begin to kick in. He felt rather… needy, the familiar drive in his nethers joined by a new sensation of a pressure building in his testicles. He had never felt that before and overall it wasn't an unpleasant sensation, but he just knew once he blasted the built up load into Rarity's wet, needy foal tunnel, it would be his best climax yet. He wished he had this potion with his prior sexual escapades.

“Oh yeah...it’s gonna be one wild night…” He muttered to himself, grinning at the thought of ravaging Rarity.

As Spike tried to make sure the potions effects didn’t cause any unwanted public displays, his eyes finally landed upon Rarity. The mare’s curvaceous figure was as beautiful as ever, the sight of her large plot swaying and jiggling with each step made Spike’s potionenhanced members twitch with anticipation. He watched as Pinkie Pie gave Rarity her order, motioning over to Spike and when Rarity saw them Pinkie gave the drake a wink before rushing back to the kitchen.

With a smile Rarity sat at the boot with Spike. “Hello Spikey. How are you today?”

“I’m doing great, been having a lot of alone time since Twilight left for that trip.” He admitted.

“Yes, I do hope she is alright though. We haven’t gotten so much as a letter from the poor dear since she left. I wonder what was so important that she’d hurry off and leave without so much as a goodbye?” Rarity asked, while Spike smiled as he watched as she took the straw into her soft lips and began to suck in a first taste of the thick potion-mixed drink. “Hmm?” She exclaimed, looking the drink over. “Tastes like Pinkie Pie added…lemons into the mix. Not too bad honestly, but I would like to know beforehoof next time.” Rarity said, returning to the smoothie.

Spike gave a mental sigh at that. He’d hate for her to have wasted the potion because of a slightly different flavor. “Heh, must just be trying new recipes.” He said. Taking a bite from his Sapphire doughnut. “So, what are you going to be doing later today?”

“Oh, the usual, working on orders and such. Thanks to my new shops and helpers I can focus on the custom orders for ponies who commission clothing. While making clothes for everypony is grand and the shops help with that, I just love the one-on-one work with customers the best.”

“Ah. Any big orders lately?”

“No, but I have the regulars. Actually, I did get an order for a dress from a Griffon of all creatures.” Rarity informed, her fruity drink now halfway gone. Spike listened to her, but kept watching to ensure she finished her entire drink. “It’s not all too different from making a dress for a pony but it has been interesting. It at least gave me a template to work with in the event others of her species wanted one.”

“Was it someone we know?”

“Friend of Gabby’s I believe. Grutha I think her name was. Sweet dear, with Griffonstone rebuilding she was able to set up a shop for her homelands exotic wares here in town.”

“That’s good. Rainbow and Pinkie Pie told me about how the city looked horrible when they first visited.”

“True, but Grutha tells me it at least resembles a propper town now, most buildings are all repaired or entirely rebuilt and the roads are finally fixed. Even managed a proper bridge across the gorge for non-griffon trade and travel.”

Spike nodded, watching as her cup was now just down to one last good sip to finish it off. “Will you be needing any help later?”

“Hmm…” Rarity thought, ignoring the last quarter of her drink. “I suppose if you don’t mind I’ll need help moving some fabrics from the basement up to my workshop. My current piece is for Prince Rutherford. He asked for something to blend both Pony and Yak cultures as a symbol for our friendship.”

“Wow, sounds important.”

“Indeed, he plans on wearing it whenever somepony of importance visits Yakyakistan or whenever he plans on visiting Equestria.”

“Well, shall we head on over to your shop? I imagine such a project needs no time wasted.”

“Why Spike, you are absolutely right.” Rarity said, getting up from her seat. “Come now, we have work to be done.”

With a nod Spike finished off his gem doughnut and followed the mare, staying behind her and her swaying, bouncing plot. The view was magnificent, only obscured by her curly tale that just managed to hide the delicious gem nestled between those pillars of soft, jiggly flesh.

"Oh! Almost forgot." Rarity said, rushing back to the table and quickly finishing off her potion-spiked drink on one go. Her cheeks hollowed out as she quickly sucked down the last remains of the smoothie. "Hate to be wasteful." Rarity said in a sing-song tone before rushing back over to Spike and out the door.

“No, no need to be wasteful.” Spike agreed with a growing grin.

The two arrived at Carousel Boutique with only a few minutes of walking, and by then Spike could clearly tell Rarity was already falling under the potions effects. She was quite flustered by the time they stepped into her shop. And once inside Rarity tried cooling herself off by turning the AC up and drinking a cold glass of water.

"Sorry for the delays Spiky, my head is just positively buzzing it seems. Feels as if I've— Well, nothing a lady should say amongst company." Rarity informed.

“Any way I can help?” Spike asked with practiced innocence.

"Oh, well, ummm…I need to clear my head some more. Oh, it's too soon for this. I don't have the pills…" Rarity said, muttering the last bit to herself. "If you'd be a dear and bring me something chilled? I just need to cool down a bit and with luck I can get started."

With a nod Spike headed towards Rarity's kitchen. He grabbed an old reliable of her's, ice cream. She's always kept a fair stockpile ready for any occasion. Of course he also reached into the fridge, finding a bottle of Sweet Apple Acres special hard cider. The kind not meant for foals. He poured the contents into a large cup and readily gave the two to Rarity.

Without hesitation the mare began to inhale the ice cream straight from the carton and gulped down the hard cider, not even noticing or perhaps even caring how strong it was. The sight of her unexpected gluttony doing something for the horny drake he couldn’t describe.

Unfortunately for her, Sweet Apple Acres special cider had the alcohol content equivalent to a bottle of whiskey, and meant to be taken in shots.

As Rarity finished gorging on the ice cream Spike noticed the cider was quickly working itself through her system. Her potion-addled and now drunken mind losing most of her usual sophistication and upper-class mannerisms. "Hehe, Always good to eat my, my…hehe, oh my. I thinks you gave me the hard cider Spi-(hic)-ky." Rarity slurred, her accent waxing and waning.

“How are you feeling, Rarity?” Spike asked politely.

"Oh, I feel—I feel really hot, Spiky." Rarity admittedly, her mind was such a mess she clearly no longer cared for subtlety. "Like, like when I’m in heat. Oof—it was—it was hard walking home. Kept gazing at everypony, kept smelling things. Lovely, musky things. Hehe, oh my. I'm getting a tad needy it seems."

“And how may I help with your neediness Rarity?” Spike asked readily, wanting to hear her say it before he fulfilled her obvious desire.

"Oh-oh well that’s qu-(hic)-ite kind of you Spiky. I'd-I'd hate to be a bother. Normally I'd be better prepared for this but-but, heh, butt. I've got a big one. Wanna know a Secret? My mother taught me a spell, Looooong time ago. Puts all the fat from sweets and such into the right places." Rarity said, giving her own rear an unladylike, audible slap that sent Spike's nethers on the alert. "It's hard being a lady. Sometimes I just want to-to go wild, show off what's on me and enjoy all those unladylike feelings I get from having this ass of mine."

“You can do that with me, Rarity.” Spike said, already loving everything he’s both hearing and seeing. “I can let you go as wild as you want.”

"Oh-oh Spiky, that's so nice of you. Hehe, you know I have noticed as you grew up." Rarity said, nearly making Spike do a double take on what he heard. "And not just grow tall but I've also seen how strong you've gotten too. That dragon strength must have multiple…uses?" She asked, giving Spike a set of needy hungry eyes that nearly made the drake pounce on her like prey.

“Believe me, there are many uses.” Spike growled happily. “And all for you.”

"Oh Spiky~ Come here and make me feel like a mare." Rarity declared.

Spike didn't need to be told twice. All too readily he pounced onto Rarity, holding her close as he planted his lips to hers. She, of course, tasted of ice cream and a hint of cider, but also of a prime diamond. Cool, refreshing, and a tad minty.

With an all too eager grab, Spike took as much of Rarity's plot that could fit into his hands, squeezing the soft, ample flesh. It was everything he imagined they'd feel like and more. The sensation of Spike's hands gripping her rear sent Rarity into a moaning frenzy, all the while keeping her lips on Spike's, her tongue tasting and feeling along his teeth and tongue.

The heat between Rarity's legs met the hard eager flesh of Spike's rods. She chuckled, finding their shape and texture against her marehood strange but equally exciting as she began grinding her dripping marehood against the drake's members.

Spike struggled not to immediately ejaculate from the sensation. He broke the kiss, wanting to save the best for last. "Ooh, Spike, what are you-" Rarity spoke, her words dying on her lips as Spike kneeled down, placing his lips to her nethers. His tongue, long and snake-like broke between her vaginal lips, exploring her marehood in a sensation Rarity could not explain nor wanted to. She just wanted to experience it.

"Aaaahhh~!" She cried in bliss, feeling her marehood touched and prodded in ways no pony tongue could ever deliver as Spike tasted all of Rarity's inner chamber. Wall to wall, leaving no spot unmolested by his tongue.

"Oh-oh Spike I-I'm going to- Aaaaaaahhhh~!" Rarity cried, a release of pressure spewing out her marehood and down Spike's eager maw as he drank all of her climax. When it ended, Spike withdrew his tongue, licking his lips as Rarity eyed him, huffing deep breaths as her white fur failed to hide a deep crimson blush. "More, Spike. More~" She begged.

“So my lady asks,” Spike started, lining up both his cocks to both of his horny unicorn’s needy holes. “So she shall receive.” He growled, thrusting hard into the needy mare.

Rarity's eyes widened. Having something inserted into her marehood was not unknown to her, but the texture, shape and overall feel of Spike's cock was alien to what the fashionista was used to. It hit nerves and rubbed in a way that sent waves of pleasure through her body. Plus, having her rectum, a part of her sexual unused and neglected, suddenly widened and filled with the same sensation drove her to new levels of pleasure.

Rarity's mind went blank as she was processing the dual feelings. Her body clenched in automatic response.

Slowly, remembering his lessions with Big Mac, Spike began to slowly pace and thrust in, then pull out of his dream mare. Feeling her vaginal walls and anus clenching his cocks so needily was making it difficult for the drake to hold back the desire to blow or go rougher.

"S-Spike." Rarity finally spoke, regaining some mental functions and sobering just a tiny bit. "B-bedroom." She moaned.

With a nod, Spike began the unnecessary, yet all too enjoyable task of walking while rutting Rarity from the downstairs boutique to her upstairs bedroom.

The stairs were quite the challenge, but Spike walked slow and steady, letting his natural walking take the place of his rutting as Rarity moaned and eeped with each step up the seemingly endless stairs.

Finally though, they made it to the second floor and once inside Rarity's bedroom, Spike locked the door and gently placed Rarity and himself onto her bed.

"Mmgh, oh Spike~" Rarity moaned.

“Not going—unf—too rough am I?” Spike grunted, reaching down and groping his mare's bountiful ass.

"Fuck me harder~" Rarity begged, wrapping hooves around Spikes neck and pulling him in for another kiss.

As she did, Spike obliged, thrusting as fast and deep as he could. The bed creaking as springs were rapidly pressed.

Rarity could taste her own marehood on Spike's lips, on his tongue and teeth, and she enjoyed it. She kissed him deeper, clenching with all her might around his rods, letting go of ladylike decorum. For once, she wasn't Rarity the lady, she was Rarity the mare, and as a mare, she wanted—needed—Spike to ravage and senselessly rut her into her bed's headboard. She wanted him to break her bed, leave her sore in the morning and most of all to feel him pump hot, sticky loads of semen into her marehood, into her rectum. Then, if he was still able, again down her own maw. Just as Spike drank all her climax, she wanted to guzzle his.

Spike was getting close now. Closer than he was wanting, but he wanted to add to Rarity's enjoyment before he blew. Spike moved his tail, a fast whipping motion that he used to give her buttocks a hard slap, then swinging back around and slapping her other side as well.

Rarity lost it, feeling her rump so roughly treated, smacked and groped red and tender, sent her mind into pure bliss as she found new strength to clench harder on Spike's cocks.

The drake blew his loads, deep into Rarity's marehood and anus.

The mare's cum chamber filled almost immediately, soon overflowing with Spike's semen as it began gushing out.

Her rectum, despite being new to the treatment, welcomed the hot, throbbing load into its depths. Not a drop escaping as Rarity's abdomen began to swell.

By the time Spike finished and pulled out, Rarity was gasping, her vaginal lips gaping apart showing their creamy filling, letting semen pour out as her anus still clenched its meal tightly inside.

“W-wow…” Spike panted heavily. “That…that was…” Spike was honestly speechless at how great it felt to claim her so thoroughly.

Rarity took several deep breaths, gathering the energy she needed before acting.

With a grunt she pulled herself up, surprising Spike as she scooted back on her bed, a trail of spunk left behind on her sheets she then happily collapsed forward upon. The weight of pressure not on her abdomen let her anus's grip slip, causing a large rush of Spike's semen to spill out. First in a powerful splatter now reduced to a light trickle.

Without a word, Rarity opened her mouth, letting her tongue hang out like a dog as she licked from tip to base Spike's top cock.

The sensation brought Spike back to full mast. His testicles feeling like more than enough was left to give to the hungry mare.

“Eager for more, my sexy unicorn?”

Rarity just nodded, her tongue trailing up and down Spike's top cock. The taste of his semen, salty and musky, mixed with the taste of her own marehood, a faint sweetness, was like ambrosia to Rarity. Once the cum was cleaned off Spike's top member she moved to his second, slightly smaller one.

Part of her mind was repulsed by the idea of tasting something that had recently violated her rectum. That part of her mind was properly tossed out the window by hormones and booze as she leaned in and licked it. The taste of semen was of course present, but the taste that could only be her own anus surprised Rarity. It wasn't vile, nor what she was expecting. It tasted a little like her marehood. A different kind of sweetness and more…unexplainable.

She greedily licked the second cock clean as well. Once both were clean and at full mast, she opened her maw wide, and greedily took both members into her mouth.

Spike grunted, holding himself up by holding onto Rarity's back as the mare carefully sucked and used her tongue to caress and feel both Spike's members within her maw. Careful not to let either one out of her lip's grasp.

“Gods Rarity, you’re amazing…” He groaned happily, not believing how great she was at sucking him off.

Rarity, in an act of lust and greed that surprised Spike, wrapped her hooves around his torso, pulling the drake in enough to press his crotch firmly against her muzzle. The tip of Spike's upper, longest member entering the back of Rarity's mouth and meeting the greedy throat its next load would be traveling down.

Spike groaned in pleasure, not wanting to let Rarity have all the fun he grabbed hold of her flanks and rapidly spanked and squeezed the jiggling, soft, malleable lumps of flesh.

Spike soon began thrusting into Rarity's maw, humping her muzzle as he groped her rear end.

Rarity accepted both the flank grabbing and oral thrusting with vigor, using her tongue to caress and lubricate Spike's cocks with every thrust while also kissing the base of them each time it slammed against her lips.

Spike soon let loose another climax, this one having both his rods shoot their loads down Rarity's throat.

The fashionista managed the first gulp, and the second with a noisy chug. But at the third, her lips failed her as the seed began to leak out. First a little, then it flowed out despite her rapid swallows. Her belly rapidly swelling again as her stomach filled with dragon sperm.

Despite her efforts, she could not swallow it all, and pulled Spike's member out, letting the fresh, hot semen spray her face, get into her mane, staining it white and dripping down her nose, mouth, chin, and neck.

“Good girl.” Spike smiled.

Despite her mouth overflowing with cum, Rarity managed to look up at Spike, giving a grin. "Woof~" She said, forcing what semen was left in her mouth down her already packed stomach. After a few breaths to collect her thoughts, Rarity spoke again. "So, round two, Spiky?"

“All for you my wonderful lady.” Spike said warmly.

The two were more than eager to return to their sloppy love making. Time passed and day turned to night. Yet even under the moon's lights neither were using the bed for sleeping that night.
