A certain itch in a certain place

Rarity made an irritated noise as she shifted in her chair to once again scratch a spot on her bottom. It had plagued her as she attempted to sew for a while now and her hoof couldn’t quite seem to get it. She didn’t seem to be getting much of anything done. For the past few hours she just hadn’t been able to focus and it was irritating her. With a sigh, she pushed herself away from the machine and fabric scraps on her desk.

Checking the clock, she saw it was near noon. She supposed now was time to make lunch for Spike and herself. But first she’d check up on him in the other room and see how he was faring. She’d asked him over this morning to help her work, and of course the pining adolescent dragon had not refused.

Rarity poked her head into the main room. There he was sitting in the center of the floor among pile of papers, back turned, sorting her order forms, business receipts and other minutiae. It couldn’t have been very interesting for him. It wasn’t for her, which was why she’d asked him to do it.

Nonetheless, Rarity observed him working hard at it. So devoted, to her. Her little helper. The poor thing burning for her with a love that could never be requited. It was tragically romantic. But all young hearts must grow up sometime, Rarity told herself.

Yet here she was taking advantage of it. She felt a stab of guilt. It was little better than leading him on, constantly inviting the dragon to help her with no intention of returning his feelings. Making him do the work even she wouldn’t do, a greater occurrence than she’d like to admit. As she leaned against the doorway, she thought of all the times he’d looked at her so obviously desiring some sign of feelings returned only for her to play innocently unaware.

Her train of thought was interrupted by the returned prickling on her butt. Out of sight behind the door frame, Rarity scratched at it.

She almost chuckled thinking if Spike could see her now. There he sat right before her unaware of her grabbing at her own bottom. Oh what hormonal flames that would fan. And Rarity wondered just what desires Spike thought about enacting with her. She blushed, then chided herself for thinking such things.

She found herself imagining just what it would be like with a dragon. In a romantic context of course. But just how different would his penis be from a stallion’s? No, she mustn’t think of that. It was hardly proper thoughts for a lady, and she’d already established that the dear was much too young anyhow.

Yet Rarity found her eyes drifting to his claws. Purple and despite being scale, they looked incredibly smooth. So smooth... Of course it wouldn’t be proper to touch her in her most intimate place at all...

But she did have that most insatiable itch, right on her rear. And Spike did have those flexible fingers. Surely he’d be glad to help scratch it for her. Platonically, she clarified to herself, purely as gesture between friends. Really, really good friends.

Spike sighed inwardly as he squinted at small type on the form before him and started yet another pile of papers. There were so much different information to watch for, most of it obscure and hard to read. All this paperwork meant nothing to him and was worse than the usual chores Rarity had for him.

He’d been doing this all morning and had quickly grown sick of it, yet he forced himself to continue at a diligent pace. It was for Rarity, he told himself. She needed it done and if he could make her work just that much more easier, then it was worth it.

So, steeling himself he reached for the next sheet and—

“Spike.”

He turned to see Rarity watching from the doorway to her sewing room. She nodded appreciatively. “Darling, you’ve been doing such great work. I wonder if I could trouble you to help me with something in here?” She said before disappering back inside.

She wants my help with something else? Curious, Spike followed her in, hoping it wouldn’t take too long so he could get back to sorting.

As he entered, he saw Rarity standing by her sewing desk at the back of the room, work pushed to the side. When she spotted him she gave a strange smile.

Spike was just about to speak but his mouth closed in astonishment as it happened. Rarity turned her back to him and raised her forelegs to rest on the desk, back legs still on the floor, and presented her firm yet exceedingly curvy white butt. He gaped as her tail lifted, exposing her slick marehood and the pink of her asshole.

“Spike,” she drawled, “I have the most insufferable itch on my bottom. Could you take care of it for me?” Rariy wiggled her generous hips.

Spike felt blood rushing both to his face and somewhere lower. He stood in shock, unable to take his eyes off her uncovered posterior. The same butt he’d ogled at so many times, now with nothing hidden.

She giggled. “Go on, it’s rude to keep a lady waiting.”

For another moment, he didn’t move. He could feel his penis leave its sheathe, erection throbbing at the sight. This was happening? Rarity really wanted him to touch her butt?

She did. Suddenly his heart was pounding.

With nervous steps Spike approached Rarity at the desk. Her massive butt loomed before him now, round and white, just under eye level due to his short stature, with ample curves that coursed down into thick thighs. Not plump like Pinkie Pie, Rarity was slim with the figure of a model, but what fat she did have made its home on her toned and shapely rear. Her raised tail playfully flicked back and forth. Spike could barely think and her intoxicating lavender scent only added to his daze.

He tried to focus despite the beautiful butt facing him. Hesitantly he reached his arms and took in his small claws her soft buttcheeks before him. Gently he began scratching along their surface.

“L-like here?” he asked, worried he’d somehow completely misinterpreted the situation.

But Rarity only hummed in response, lowering her head and relaxing into her forelegs as she enjoyed the treatment. She seemed completely at ease.

That was all the encouragement Spike needed, and enthusiastically he took up his new task. With the greatest care he scraped against those furry globes. His claws scuffed at her flanks, first in an up and down pattern along her cheeks, but that soon didn’t seem enough. Rarity hadn’t told him exactly where to itch and her rear was so big he couldn’t grasp it all at once so he resorted to grazing in lazy circles, occasionally reaching down her slopes to the back of her thighs and back up to the base of her tail.

He was without words. For a while there was only the hums of Rarity and rustling of fur as he moved his hands through her butt, kneading and rubbing the firm muscle as he scratched. He was captivated by the glistening slit just under his hands, swollen and wet, from his actions. It was heaven and Spike couldn’t imagine anything better than the sight before him and the sensation of the soft skin in his palms.

Then Rarity cooed, “Oh, Spike, that does feel so wonderful. But, I’m afraid my itch is somewhere a bit more intimate, if you don’t mind.”

That stopped him. Intimate? Spike wondered. Adrenaline rushed through him. She wanted him to go further than this? Forbidden late night dreams and fantasies played out through his head. But, he realized, she hadn’t mentioned vagina, she’d said bottom. Did she mean her butthole?

Her tail was still off to the side. Curiously Spike leaned in closer and for the first time got a good look at her anus. Just under her dock, it stood proud and exposed. The muscle looked strong and tight, as though it had never been stretched open before, a vibrant pink ring that looked so inviting and he found himself wanting to touch it.

Unsteadily Spike moved a hand from her cheek and drew it to the center, starting at the base of her tail and tracing down the dark curve of her crack. Her fur was thinner here and as his index finger neared her bright tailhole the muscle contracted in anticipation. Her whole rear tensed. Then his finger arrived, and he stroked her anus.

Rarity twitched at his touch and let out a breath, resting head lazily in her forelegs. He himself let out a breath he hadn’t known he was holding. Gentler than before Spike moved his finger scratching along the ridges of her ring. He took in the sight of her ass and his finger touching it, her sphincter exuding warmth as he scraped against it. Her puckered flesh quivered at his ministrations. He was diligent to cover the entire small surface and Rarity sighed contentedly whenever he pressed in a bit firmer, almost tickling as he worked his treatment of her anal hole.

His erection felt like it was going to explode. He’d had fantasies about doing all sorts of things to her, but nothing like this. He never thought something could be so hot. He was scratching the tailhole of Rarity, the mare he’d lusted over since moving to Ponyville!

But still that wasn’t enough for the mare, who eventually glanced back and said, “I’m afraid the itch is a little deeper. Could you maybe go inside?”

He almost came right there. Now she wanted him in her butt? “Yes! Sure, I mean I can do that!” he nodded vigorously, desperate to do so before she somehow changed her mind.

Leaving the rim, Spike placed the tip of his finger at the center of her hole, prodding the narrow exit. Finding it firm yet flexible, he began to gently push his claw in against the resisting muscle and slowly it slid into that glorious tailhole, swallowing him eagerly to the first knuckle.

Spike had never in his young life been so aroused as when he felt her pink ring squeeze down around his index finger.

“Oh,” Rarity shuddered and moaned in response. “That’s it, just the spot. Don’t stop!”

Spike found himself somehow getting even harder as he dug his index finger yet further into her butt, stroking the warm, tight walls. He wormed his finger through her pulsing rectum and massaged her muscles as they constricted against the intruder, searching out that phantom itch. The grip of her internal walls clenched around him so hard he could barely bend his digit to scrape. His other hand still grasped her ass which pushed back against him, trying to get him in deeper. Rarity tossed her head in satisfaction and he could feel her hind muscles flex in his palm as she squirmed.

She moaned as his claw scratched against a particularly sensitive spot.

It was too much. He wanted to shove his face in her crack and inhale her scent as she sat on him, pressing those huge cheeks against him. He wanted to just let go and fuck her ass senseless until he ejaculated deep in her rectum. It was difficult to restrain himself and stand here as he sedately pleasured the mare before him with only his finger.

Apparently Rarity thought something similar. “Harder, please!” she cried, rolling her hips. “You can go deeper, Spike, don’t hold back!”

He almost groaned himself. He’d give her what she wanted. Spike drew his finger from her asshole then mindful not to prick her, hilted it once more. Dropping all pretense of scratching he pushed in again and began thrusting his finger in and out her quivering hole. He sunk his finger in as deep as it would go and writhed it, stretching her sphincter in different directions.

Rarity clutched at the desk and her tail spasmed. Desire spurring her, her moans grew louder, “Fuck... Spike, yes, that’s it. That’s just the spot!”

Her cries flared something deep within him. He longed to stroke his length but couldn’t bring himself to stop groping her thick white butt for a moment. Spike moved faster, driving his finger and pretending it was his cock. He imagined her already tight hole even tighter stretching to accommodate his throbbing young erection, her hot cavity enveloping him. He brought his head close to smell more of her feminine arousal, watching those squirming glutes before him as he pounded her anal passage.

“Yes, yes, put your finger deep in my ass!” The mare cried.

With one last shove he embedded his finger in her rectum, and finally Rarity came. The muscles of her rear tensed and her marehood convulsed, a small amount of fluid squirting to Spike’s chest. Keeping his finger bottomed in her, he reveled in the feel of her muscles contracting wildly through her orgasm. The mare let herself fall limply on the desk as it passed.

Then, still breathing heavily, slowly Rarity moved her hips forward and pulled away, his finger sliding out.

Spike watched her demount the desk, feeling strangely fullfilled yet unsatisfied. He’d made her orgasm just from his finger in her butt. Yet still his penis painfully throbbed for more. But he knew this was more than he already could ever have expected. He thought better of it, yet couldn’t help himself. “Do you... think I could do more?”

Rarity turned around toward him. She looked at him, then giggled, her voice dancing into his ears. “Now, Spike. That was wonderful, but I hope you understand we mustn’t go any further. Merely a gesture between very good friends.”

He looked down. “Oh.”

“However,” she continued, “perhaps we could do this again next time I’m feeling a particularly bothersome itch?”

Spike felt hopeful at that. He longed to do so much more. But he wouldn’t give up what just happened for all the world, even if it was just scratching her ass. He answered, “Yeah... I would like that.”

“Excellent,” Rarity beamed. “Now, how about we go have lunch. And be sure to wash those little hands of yours.”

So began Spike’s sessions scratching Rarity’s butthole.
