Oh!
Spike, having fled home with as much haste as his short legs could muster - and, eventually remembering that he had wings now, having flown as quickly as possible - had retreated upon arrival at the castle to his room, where he was safe to nurse his confusion, his embarrassment, and his pride.
How many times? he wondered. How many times has she seen me jacking off?
It was almost arousing, actually. To think that somepony as adorably sexy as Princess Twilight - not that he thought of her in that way, of course - should have seen him, watched him, as he pleasured himself in the comfort of his room. . . He thought back to the conversation they had just had, and winced at the concern she must surely have felt as he not only fainted - ouch! - but, as soon as he came round, ran away.
What must Twilight be thinking? he asked himself. And, not knowing the answer, he didn't reply. But he suspected she was feeling rather hurt and confused.
In actual fact, she was experiencing neither of those emotions, and was rather nearer to Spike than he himself realised. As soon as Spike had come round, remembered what they had been talking about and what her last question had been, he had disappeared into the distance, as fast, apparently, as he could go.
Now, Twilight was a logical pony. If X happened she knew, without the merest shadow of a doubt, that Y must have caused it, because of reason Z. So if she applied this rationale to the present situation:-
X: Spike ran away. Y: He was embarrassed - that much is obvious. So Z must be. . . She thought for a moment, trying to piece together what had happened. She had been asking him how sex worked, and then been confused as to why she sometimes saw him rubbing his colt parts - sorry, 'penis' - without the presence of another pony (or dragon). So, naturally, she had asked him why he did this - and that must be Z. He was embarrassed at that question!
So why should he be so ashamed at being asked that? Perhaps it was time for her most favourite of activities: Research in the library!
With that thought uppermost in her mind, Twilight focussed her arcane energy and, with a bright flash of magenta light, a loud CRACK of sound, and the merest, almost unnoticeable release of a minute amount of gamma radiation, she teleported back home, appearing milliseconds later in the castle library - arriving a full twenty minutes before the breathless Spike.
Without further ado, she set about conducting her research. Where to begin, though? That was the question. She had no idea what it was called, this penis-rubbing thing, so how to start learning about it? Perhaps I should just start with 'penis', she thought. Yes - I'll do that.
So she quickly - and incredibly efficiently - made her way to the 'Biology - Equestrian' section of the library. This was a subject she was rather familiar with, having learnt much about magical biology during her time at Princess Celestia's School for Gifted Unicorns, but there was one subsection which she had always, always steered clear of. "Ah, here is it," she murmured aloud. "'Biology - Equestrian - Sexual'."
She blushed, mentally hushing herself, before reminding herself that she had every right in the world to be here, and that no-one was going to come along and punish her for reading the books herein. During her early adolescence she had, in fact, been going through random books in her parents' small library back home in Canterlot, and their reactions when they came across her reading a book entitled Kinky: Interesting & Unusual Sexual Activities for the Jaded Couple (written, incidentally, by none other than the now Princess Cadance) had been more than enough to ensure she was far too frightened to ever try reading such books again.
Even now, she had to suppress a guilty glance over her shoulder, swallowing nervously, as she carefully scanned the titles of the books in front of her. Sexual Practices of pre-Equestrian Earth Ponies - interesting, but not quite what she was after - Pegasus Fetishism: Why Wings Matter - that didn't sound helpful - and Help! My Partner's a Sexaholic! - which, though a fascinating-sounding concept, didn't seem right either.
Eventually, however, she hit upon a title which sounded helpful: Self-Pleasuring: A Mare's Guide. This 'self-pleasuring' business sounded like the sort of thing Spike had been doing, so perhaps there would be the best place to start.
With this in mind, Twilight slid the slim volume down from the shelf, and flew lightly over to one of the large, ornate reading tables she had had installed (weirdly, the Castle hadn't come with tables other than the Cutie Map - despite having pretty much everything else).
Having pulled up a comfortable chair, and with the late afternoon sunlight streaming pleasingly through the arching, Gothic-style windows, the Princess sat down to read. . .
Half an hour later, Spike was to be found enjoying a quiet afternoon nap. The warmth of the day's sun, combined with the effort expended in running (and flying) all the way home, and the strangeness of the morning's conversation with Twilight, had all conspired to wear him out. And so he had decided to have a short snooze, being well past the age where admitting to being tired was something to avoid at all costs.
He was dreaming pleasant, though elusive, dreams, when he was brought back to his senses by the repeated sound of knocking at his bedroom door. Blurrily, he rubbed his eyes, still half asleep, and not yet fully aware that the knocking was, in fact, real, and not just a continued figment of his disturbed dreams.
After a few seconds, however, as he gradually returned to full wakefulness and the knocking continued, he realised that there was actually somepony at his door who wanted to be let in. And as Starlight was currently away, touring the nearby towns with Trixie and unlikely to be back before tomorrow evening, that meant that the only pony who could be outside was Twilight.
And Spike was not sure if he wanted to see Twilight, just yet. Not that he was angry, or annoyed with her - far from it. He was merely still somewhat embarrassed at the thought of having been watched whilst. . . 'enjoying the pleasure of his own company', by her. And thus it was with some reluctance that he got up from the bed and wandered slowly over to the door.
Taking a deep breath, he pulled it open - and there indeed was Twilight, looking rather more red in the face than usual, and hopping up and down in that way she did whenever she was uncertain about something. "Ah, Spike!" she greeted him, as though nothing had happened. "I wondered - well, I wondered if you might be able to - to explain something to me."
Spike raised a questioning eyebrow; it was then that he noticed that Twilight was carrying a slim book of some description, levitating it in her magic to the left of her head. His surprise - and not a little consternation - grew as he read the title of this volume: Self-Pleasuring: A Mare's Guide. He hesitated, unsure of what the Princess might be about to ask. "Er. . . sure, come on in."
So saying, he held the door open while Twilight trotted eagerly within; once inside she went over and sat on the edge of Spike's bed; Spike himself came and sat next to her. Before she could say anything, he first wanted to apologise for his earlier disappearance. "Hmm - sorry, Twilight, about earlier. I didn't mean to run away like that. You just - surprised me, is all."
Twilight shook her head; "Oh, that's alright," she reassured him. "I didn't know at the time why you might be embarrassed, but I think I understand now!"
She brandished the booklet whilst saying this, and Spike swallowed. "I see. . ."
She nodded again, evidently very proud at having learnt something new for herself on a subject she had previously been completely in the dark over. "Yes - I've been learning about mass-ter-bay-shun."
The way she said it made it clear to the dragon that this was the first time she had ever pronounced it aloud. "Right, I see," he intoned again. When she didn't seem about to explain any further, he prompted her by saying, "So. . . you wanted my help, with something?"
"Oh, right! Yes. Well, y'see - this book explains all about masturbation, and how it works, and I think it sounds very interesting - but I don't know - I don't know how. . . You see, I don't know if I'd - If I'd be any good. At it."
Spike raised his eyebrow again; with the amount of exercise his eyebrows had got over the past few hours he'd have to be very careful to keep his calorie intake high enough. "O-kay. . . And what do you want me to help you with?"
Though he would never have admitted it, least of all to himself, Spike was finding the topic of conversation, especially with the highly physically attractive Twilight, rather stimulating; and on top of this there seemed to be some sort of. . . 'aroma' about which he found very arousing. He could feel his member beginning to harden, and quickly shifted his position to try to hide it.
Not noticing his discomfiture, Twilight hastened to explain. "Well, you see - I was wondering if you might be able to show me how to do it. To masturbate, I mean."
Spike almost choked on his own tongue in surprise; "What!?"
The Princess seemed to realise she had said something unexpected; "Oh, I'm sorry! I didn't mean to - to worry you!"
"No, no, it's fine," Spike reassured her, now scrunching his legs together uncomfortably in an attempt to keep his erection hidden. "It's just. . . Wow. I would never have expected you to - You really want me to show you?"
Twilight nodded again, relieved that his initial shock seemed to have passed. "If that's okay - the book is very helpful, and I'd like to try out what it suggests, but I think a demonstration would be useful. I don't want to get it wrong, or anything like that! So yes, if you don't mind. . ?"
"Mind? Of course not!" Spike replied hurriedly. He had just realised where the source of that wondrous aroma was - and, as he watched, a tiny, damp stain could be seen spreading slowly from beneath where Twilight was sitting. It seemed that he wasn't the only one to feel aroused!
"Well, if you're sure you don't mind," Twilight said. "I don't want to embarrass you again."
"No, that's quite alright. Are you sure this is what you want to do? You want me to show you how to masturbate?"
After Twilight had nodded in agreement, Spike told her what to do next. "Well, in that case - the first step is to become aroused; that's your body's way of getting ready for sex."
"Oh, I see - that sounds like what the book said."
"Excellent. And I can see by the wet patch beneath you that you're already pretty ready!"
"What? Oh!" Twilight had apparently not noticed the steadily, salubriously leaking liquid which had been dripping from her nethers for some minutes. "Oh dear - I hope that doesn't stain! I'd forgotten the book mentioned that might happen."
"That's okay, it'll wash out." In fairness, he really didn't mind Twilight's juices seeping into his bedsheets in the slightest. Turning his attention to her fully, he announced, "Right. If you come up the bed and lie on your back, propped up by my pillows, with your knees apart, that'd be great."
She listened carefully to his orders before complying. It was with rapidly quickening heartbeat that Spike caught his first glimpse of Twilight reddened, dripping pussy, which remained in full view as she pulled her legs wide apart. "Like this?" she checked.
"Perfect, just like that." Spike now stood up, letting his boner stick out in front of him; he heard Twilight's muted gasp as she saw an erect male member for the first time in her life.
"Hmm. . ." she murmured.
Spike winked. "Yup! This is called an 'erection', though there are lots of more common words too. Are you ready for me to begin the lesson?"
As the dragon clambered back up onto the bed and sat down facing her, sitting just in front of her, she nodded, swallowing in anticipation. "Ready when you are, Spike."
"In that, case. . . Now that you're all ready and wet," he indicated her sopping pussy with a wave of his left claws (the right were already busily engaged in gently stroking his own throbbing member, much to Twilight's gratification), "You can begin to stroke yourself with a hoof."
Leaning back on one elbow, Twilight reached gingerly forward and, ever so slowly, pressed a hoof to her reddened area; at the touch her eyes rolled back and the moaned, "Ooh. . . that's nice. . ."
Spike watched her gratuitously as she made her first attempt at pleasuring herself in her life, enjoying every second of it. She continued to touch her pussy gently, before beginning to carefully rub very slowly up and down, experimenting with the sensation until she settled on the perfect rhythm, moaning again, "Hmm. . . that feels so good. . ."
She opened her eyes again, mouth open slightly, cheeks a bright red. Spike, who had continued to fondle his own member whilst Twilight was so doing, licked his lips, and murmured, "Would you like me to give you a claw?"
Breathing raspily, Twilight nodded, removing her hoof after one final, quick rub. Spike ooched slightly forward on the bed, his knees now touching the inside of Twilight's, and looked up at her with half-lidded eyes. "Are you ready?"
She nodded eagerly, licking the residual quantities of her own juices from her hoof. Spike, his left claws fondling his balls, reached forward with his right to stroke down the length of Twilight's inner thigh, from bottom to top. She moaned in pleasure at this teasing touch; "Hmm. . . that's good, Spike. . ."
Enjoying and rapturous look on her face, Spike hesitated a few seconds longer, drawing out the moment until he was sure she could wait no longer. Just as she was about to ask him when he was going to start, he lunged forward, planting two claws firmly against her puffy nether lips.
She gasped, "Oh! Oh wow! Oh - oh yes that's good. . ."
Spike began stroking her nether regions up and down, up and down, paying attention to her outer folds before pushing gently past them to insert a claw within her vagina. She groaned, her muscles tensing in appreciation; "Ah! Oh that's good, keep doing that. . !"
The dragon obliged, willingly, pushing a second claw gently past her outer folds - but being carefully not to touch her most sensitive organ, the clitoris. He was saving that for something really special. . .
He continued to finger her for several more seconds, first rubbing the outside of her folds, then pushing past them to gently caress the inside of her love-canal, before reverting to stroking the outside. All of this she found intensely pleasurable, giving cute moans and gasps almost constantly. "Ooh. . . oh! Oh yes Spike, that's good. . . that feel so good. . ."
With this feast for the eyes, the wonderful, arousing scent of Twilight's natural lubricant wafting through the heavy air, and his own ministrations never letting up for a second, it wasn't long before Spike felt himself beginning to reach his climax, and he hurriedly let go of his cock lest he cum too soon. Perhaps it was time for phase three of 'Teaching Twilight to Clop'. . .
With this thought in mind, he withdrew his claw from her nethers, licking her juices from them eagerly. Twilight, who had been lying back with her eyes closed, propped herself up again, opened her eyes, and asked anxiously, "It's not over, is it? I don't want it to be over yet!"
"Don't you worry, Twi'," Spike reassured her. "We're almost there, but the best is yet to come!"
Twilight smiled in relief; having never had any form of sexual contact with anyone else in her life, this whole experience was both incredibly enjoyable and rather overwhelming - but nothing would've made her back out now. She waited, tense with anticipation, as Spike changed his position, moving to kneel on all fours, his head not far from her crotch. "Are you ready for the best feeling in your life?" he asked her, enticingly.
She nodded hungrily and, without further warning, the dragon lunged forward and planted his mouth over Twilight's aching pussy.
"Hnng! Ooh, oh sweet Celestia that's amazing!" Twilight contorted, her muscles quivering in delight at the astonishingly, intensely pleasurable sensations emanating from her soaking vulva. "Ooh, oh yes! Oh my. . ."
Spike, too, was enjoying himself, savouring the warm, sweet scent and juicy, slippery sensation of Twilight's dripping pussy on his tongue. He began by licking up and down her length, teasing her outer folds, before suddenly pushing his searching tongue deep inside her.
"Oh! Oh, oh, shit that's good!"
Spike was so busily engaged the uncharacteristic profanity barely registered; he was preparing for his pièce de résistance. He could hear Twilight's breathing speeding up, becoming shallower; he could sense her muscles contracting in pleasure and desire, and he could feel the heat radiating from her pussy - he knew she wasn't far from cumming.
With one arm rubbing his own member feverishly, he reached up with the other and grasped hold of one of the Princess' breasts, rubbing the teat through his claws, and squeezing her firm bust masterfully. Timing everything to perfection, he heard Twilight's spasmodic moaning turn to a steady, yearning groan and, as if on cue, began rapidly licking and sucking at her hot, pulsing clit.
"Oh my! Oh my days! Oh, yes Spike, yes!"
Burying his muzzle deep inside her folds, Spike sucked powerfully on her swollen cherry, willing her to orgasm with him.
And at that second, something seemed to snap within her - without realising what was happening, she came, bringing her legs together and clenching down tightly on Spike's head, forcing him to continue his eager sucking of her nub, kissing and nibbling at her folds.
"I, I, I - argh! Oh, oh yes! Yes, yes, yes, yes! Hnnng, hmm, yes! Oh my, oh shit, shit shit! Agh!"
She squirted thickly into Spike's mouth, coating his lips and teeth with her warm, aromatic juices, and at the same moment Spike cummed too, spreading his seed over the bedspread, as his lips burrowed further into Twilight's nethers, thirsty for more sweet, sweet filly nectar; he moaned into Twilight's pussy, the vibrations extending her orgasm still further.
"Oh, oh yes! Oh, oh shit that's good - oh, yes!"
Eventually, as the last of Spike's cum sprayed unceremoniously from his throbbing cock, and Twilight's body ceased to shake and quiver with delight, she fell back upon the pillows, and spread her legs wide apart, releasing the lube-coated dragon to breathe.
Taking deep, welcome breaths of fresh air, Spike crawled, exhausted, to lie next to the Princess. Together, the two of them panted their way back to normal, heedless of the liquids still dripping from their privates, and mindful only of the wonderful experience they had just shared.
After several minutes, and as his breathing finally returned to normal, Spike leant forward and planted a wet, sloppy kiss on Twilight's lips, allowing her to taste her own squirt. She turned to smile warmly at him, whispering in pleasurable weariness, "Wow, Spike. . . That was - that was amazing. . ."
He nodded in spent agreement. "Yeah. . ."
A few minutes passed by, each of them simply enjoying the other's company and nearness without the need for words. Eventually, Spike cleared his throat, and murmured, "Best keep this to ourselves though, 'kay?"
There was no reply - for, thoroughly overtired from her first, thrilling sexual experience, Twilight had fallen fast asleep.
Smiling to himself, Spike lay back, and closed his eyes, in bliss.
