> A Lesson in the Library
> --------------------------------------------------------------------------

The familiar halls of the Canterlot library helped to relax Dusk Shine’s mind as he studied. Celestia had given him more to report back on than usual, and while he was on track to finish twelve hours early, he had wanted to finish a full day early. The last book he needed to read was nearly finished, a dry old tome about the logistical benefits of magically enchanted wagon wheels in ancient Equestrian warfare. It was the best book Dusk Shine had read all week, but he needed to finish it quickly.
From down the hall, the creak of old hinges told him that someone else was in the library with him now. A bit odd for three in the morning. He paid it little mind as he absorbed the last couple of pages of wonderful preclassical writing. With a satisfied smile, Dusk Shine flipped the book closed, levitating it over to the piled, taller than him, that had built up at the edge of the table. That was the last one. All that was left was to write out the report.
“Dusky? You in here?” It was Cadence that had shown up so late. That was odd.
“Over here.” Dusk didn’t even look up as he replied, the table already glowing with the purple of his magic as he furiously scribbled out sentence after sentence onto fresh parchment. He could hear Cadence’s hoof getting closer. When she rounded the corner, he could hear the amused chuckle.
“You know that could’ve waited until morning?”
“I like being done early. Gives me more time to read after studying.”
“So you read at night to give you time to read in the afternoon?” Cadence teased. Dusk looked back with a smile.
“You don’t have to make it sound so bad.”
“I’m only teasing. I just came by because your sister was worried you weren’t getting any sleep. Seems she was right.”
“Well, family knows family. I’m just finishing up my last report. I can sleep when that’s done.”
“How far along is that?” Cadence asked. Dusk Shine wasn’t even looking at the paper as the quill kept doing its work.
“Hm, probably another half hour or so.”
“Mind if I watch?”
“You just want to make sure I actually go to sleep once I’m done.” Dusk replied. Cadence giggled.
“You caught me.”
“Well, I don’t mind if you watch as long as you let me concentrate for just a bit. We can talk after.”
“Of course.” Cadence said. She spent the next several minutes quietly watching Dusk Shine work. The quill was a blur as Duck Shine put words to paper. The report was easy enough, he had been writing it in his head even as he was finishing the book. Before long, the report was done, a neat stack of parchment covered in tidy black ink.
“Done.” Dusk Shine muttered to himself, satisfied. 
“Great to hear. Now…,”
“Bed?”
“Bed. Come on, I’ll walk you back.”
“You don’t need to.” 
“Well, you know me, once a babysitter, always a babysitter.” Cadence gestured Dusk to get up and the two of them began to walk to the entrance of the library together.
“Hey,” Dusk had thought of something as they moved through the halls of books, “Why are you up so late? You said Gleaming Shield was worried about me, but that doesn’t explain why the two of you were still awake.”
“Well,” Cadence blushed a bit, “We were having a bit of a romantic evening.”
“Oh, that sounds fun. What did the two of you do?” Cadence’s blush deepened.
“I think…, well you know”
“What?”
“No offense, Dusky, but you can be a bit dense about some things. We, you know, had sex.” Dusk paused, staring at Cadence long enough that the older mare worried she had overshared.
“What’s romantic about that?” That question stopped Cadence in her tracks completely. She looked over to Dusk to find his expression completely serious.
“What?”
“Sex. What’s so romantic about that?”
“Dusk…,” Cadence had to stop herself from laughing, “Do you even really know what sex is?” Dusk looked irritated with the question.
“Of course I do. I’m not a child.” Duck straightened his back, his voice going into perfect-student mode. “Sex is the process by which some organisms reproduce. The male of the species inserts his penis into the….”
“Ok, Dusky, I didn’t mean did you know what sex is scientifically. Knowing you, you probably found that in a book years before you should have been learning about it. Sex is so much more than what a medical book can teach you though.”
“Medical textbooks teach you everything you need to know about the process.”
“Yes, but they can’t teach you about the passion, the intimacy, the pure pleasure of the experience.”
“Passion?” Dusk’s brow furrowed in confusion. “What can be so passionate about a flesh piston pushing into a hole?”
“Oh my Celestia, Dusk. I have never heard such a wonderful experience be described so emotionlessly…, or disgustingly.”
“Maybe it's just something a pony needs to experience first hoof to properly understand. Sometimes a thing can only be truly understood by doing it.” Dusk shrugged and moved to keep walking, turning around when he noticed Cadence wasn’t following. The mare was biting her lower lip, a thoughtful look on her face. Something about the way she was biting her lips made Dusk feel a tingle.
“My my, that’s the smartest thing I’ve heard you say all night. You have a point. Sometimes, first hoof experience is needed.”
“Cadence,” Dusk wasn’t sure he liked the way his former babysitter was looking at him, “What are you thinking?”
“A solution, Dusky. How about you get some first hoof experience?”
“Look, if you are trying to set me up with somepony, please don’t. I don’t have time to date right now.”
“First of all, yes you do, but I won’t pressure you on something like that. Second of all, you don’t have to date somepony to have sex with them. All you need is a little…,” Cadence closed the gap between them and whispered into Dusk’s ear, “...attraction.” Dusk pulled back in shock, struggling to reply.
“Cadence….”
“Yes?”
“Are you…trying to seduce me?”
“I am trying to help you.” Cadence closed the gap again, even slower this time. Dusk didn’t move away. Having a mare as attractive as Cadence be so close to him with an expression like the one she was wearing and talking the way she was talking did excite him. It wasn’t a completely unfamiliar feeling, Dusk had been attracted to mares before. However, this was his first time having a mare be so forward, and it was Cadence of all mares. 
“This feels…,” he struggled with his words as his body tensed. Cadence’s hoof was on his shoulder now, her face mere inches from his. “What about Gleaming?”
“Your sister will be fine. She knows that love is my area of expertise, and she will understand.”
“It still feels weird.”
“Soon it won’t.” Cadence leaned in more. “Soon it will just feel amazing.” Then, the tension was finally released. Cadence closed the last of the gap between them and pressed her lips to Dusk’s. The young stallion’s body felt like a jolt had passed through it. For several seconds the two of them stood in the halls of the library, their lips locked in a gentle kiss. Cadence was the one to break the kiss. She pulled away and brought her lips to Dusk’s ear and spoke in a breathy whisper.
“Do you know someplace we can be alone?”
“There’s an old nook,” Dusk was almost stuttering, his hoof shaking as he pointed, “The section on Applied Lumiostasis. Nopony ever goes in there but me.” Cadence’s eyebrows raised.
“Sounds like it’s dusty.” Dusk was about to apologize and suggest another location when Cadence suddenly bit his lower lips gently before whispering again. “Sounds intimate.” Dusk blushed as he realized that he had grown hard just listening to her speak to him like this. His cock twitched between his legs, excited for the experience he was about to have. Cadence noticed and her smile widened. “Looks like the little guy is excited to play. Lead the way Dusk. Let’s give your little friend what he wants.” Dusk was more than happy to do as Cadence asked. Not only was his mind growing more consumed by lust, but he was also nervous about the guards he knew patrolled the halls. He didn’t like the idea of being caught with an erection while with his sister’s significant other. So, he moved past Cadence and tried to walk calmly down the hall.
“It’s over this way,” he said nervously. He tried to walk so that he could hide his cock with his tail, but when he looked over his shoulder he knew he had failed. Cadence was following him, but her eyes were looking down towards his cock. She was lightly biting her lip. Dusk assumed that was a good thing, but it still made him embarrassed. The walk to the quiet little section of the library was awkward, but also exciting. Dusk would be lying if he tried to say he wasn’t looking forward to what Cadence wanted to show him. He was still a bit perturbed about her suggesting he didn’t understand sex, but she was the expert.
Cadence followed at a good distance, watching Dusk’s awkward attempts to hide his erection while walking. It wasn’t very easy for ponies to keep that kind of thing a secret. Gleaming Shield was understanding about what Cadence did. If anything, she would be happy to hear Cadence had helped her sister out. So, guilt free, Cadence thought about what she would do to the stallion. He was new to the whole experience, so she couldn’t do anything too wild. Additionally, the point to this was to show Dusk that sex could be intimate and romantic. With that thought running through her head, she quickly decided what she was going to do. There was one option that met every requirement she had.
The walk finally ended with Dusk pushing a small metal door open with his magic and gesturing her in. Cadence stepped into the small room. She could see why Dusk picked it. As expected from a library section on a concept as…underappreciated as Applied Lumiostasis, whatever that even was, the room looked like nopony had been inside of it in years. Well, no quite nopony. There was a small area in the corner with a used coffee mug that had been left out and several used candles. Dusk Shine really did like his obscure subjects. The room was a bit dusty, but that was an easy fix.
Dusk shine closed the door behind them before standing awkwardly in the middle of the room. Cadence’s magic lit up and brushed against the whole room. Flecks of dust lifted up with it as she carried it to the trash bin next to the door. Dusk moved aside to let her place it inside.
“Really, Dusk,” Cadence chided, “You couldn’t dust in here? From the looks of it, you’ve spent hours in here before.”
“It's the staff’s job.” Dusk pouted.
“Still, you chose to study in here.” She shot him a teasing wink. “You decided to have your first time here. The least you could have done is clean up.” Before Dusk could counter her, Cadence hooked her hoof around his and guided him to a cushion. The library was full of colorful cushions for guests to sit on. Unlike the rest of the room, those at least looked nice. Cadence suspected that Dusk had brought them in from another room. Whatever the reason, they would do just fine. Using her magic, she pulled all of the cushions nearby into the center of the room. Then, she pushed Dusk down onto them.
“So,” Dusk’s voice sounded nervous, “We are just going to do it?”
“Well,” Cadence crawled onto the cushions with him, “First, I am going to teach you to appreciate a little intimacy.” She was right by his lower legs now. Her hooves touched his thighs gently, then pushed them apart slowly. Dusk’s cock was hard and twitching against his stomach by then. “Someone’s excited,” Cadence commented, as if she hadn’t had a full view of his cock for several minutes already. “Is it alright for me to start?” Dusk took a second to process what she was saying, then nervously nodded. 
The young stallion’s legs were shaking slightly, probably both from the nerves and from excitement. It made Cadence smile. She loved breaking in virgins. She leaned down so that her face was inches from his twitching cock. Cadence put her mouth against the head of his cock and gently slid her tongue along it. The reaction was immediate. Dusk sucked air in at the unfamiliar sensation. Cadence looked up at him with the tip still in her mouth, locking eyes with him so he could see her face as she showed him a good time. His eyes were glued to the action. 
Moving down a bit and taking the tip out of her mouth, Cadence slid her tongue along Dusk’s shaft, starting from the base and slowly moving up. She could feel his legs squirm in her grip as she held them apart. When she reached the tip again she brought the cock back into her mouth and pushed it in deeper than before. She toyed with his sensitive part with her tongue slowly, sucking and slowly bobbing her head. When she pulled back off of him that time, Dusk gave a weak sound of disappointment.
“Don’t worry,” she whispered, “I’m not done.” She returned to the base of his cock and gently took one of his balls in her mouth. She used her tongue to gently stroke his ball, the rough feeling on the sensitive flesh getting more of a reaction out of him than anything so far.
“The diagrams didn’t show anything like this.” Dusk muttered in amazement before softly moaning. Cadence had to fight not to laugh as she pulled her mouth free again.
“I told you the books don’t include everything. Well, at least the kind you read don’t. I have some rather fun one’s I’d be willing to let you borrow if you want to do some… homework on what you learn today.”
“Yes please.” Dusk didn’t even say that in the usual tone he had when talking about books. He was lost in the moment and clearly just wanted anything that could make him feel like he did at that moment. Cadence returned to the task at hand. She could see that Dusk had already learned his lesson, but she was far from done. She wouldn’t be content until she had made the inexperienced stallion cum. The way things were going, she would probably need to take things slower or risk it happening prematurely. 
“Time for the real thing,” she said before taking him back in her mouth. Cadence began to bob her head, taking Dusk in deep with every motion. It had been a while since she had deepthroated a stallion, but from the sounds of Dusk’s moans she had lost none of her skill. Dusk’s cock throbbed in her mouth as the stallion squirmed more. It wouldn’t take much to set him off, at least not the first time. That was fine though; she had plans.
“That feels….” Dusk was breathing faster and faster. He didn’t finish what he was saying, but he didn’t need to. His hooves went unconsciously to Cadence’s head and she could feel him gently pressing her down on every bob she did. His moans were getting louder. Cadence pulled him out of her mouth and raised herself up to head level. 
“No,” Dusk’s eyes were glazed over with pleasure, but the disappointment in them was clear, “Don’t stop. Don’t stop.” His pleading chant was quiet and desperate. Cadence’s magic lit the room as she gently massaged his balls and stroked his cock, her lips inches from Dusk Shine’s face.
“You still think there’s nothing romantic about sex?”
“No.”
“You still think your textbooks told you everything you needed to know about it?”
“No.” Dusk’s voice was growing more and more desperate. The magic stroking him off was keeping him on edge, but it wasn’t allowing him the release his body craved. 
“Do you want me to help you cum?” Cadence’s whispers sent tingles through Dusk’s body. The stallion met her eyes and nodded.
“Please.” It was all Cadence needed to hear, she was done teasing now. Slowly, she got back into position, stroking the stallion’s cock as she did. When she was back in front of his dick, she dragged her tongue slowly up the shaft one last time before reaching the top and closing her mouth around it. Then she began to deep throat him again, this time with more energy than before. Dusk’s reaction was immediate. His breathing grew quicker and his moans louder. No matter how private the room was, if there were guards in the hall outside, there was no way they couldn’t hear what was going on. Neither pony seemed to notice or care. 
After only a few more short moments of Cadence’s skillful attention, Dusk finally reached his limit. He held her head down on his cock with his magic. Cadence was strong enough she could have pulled off if she needed to, but far from removing herself, she instead hilted him inside of her throat and began swallowing. Dusk came hard inside of her. His cock pulsed as it shot its load into her throat. The mare milked him dry, coaxing every drop of cum he could produce out of him and swallowing all of it. The pleasure was overwhelming for Dusk, and Cadence could see it. She smiled as best she could with a cock in her mouth as she delighted in her victory. 
When it was finally over, Dusk flopped back into the cushions. He looked dazed, lost in the aftermath of his orgasm. Cadence walked over to him so that she was hovering just over his head. Her horn glowed pink and Dusk felt something strange come over him. His cock, which had softened after the orgasm, was now hard and twitching again. 
“What are you doing?” Dusk asked.
“You don’t think the lesson is over yet, do you?” Cadence purred. It really should have been, but there was no harm in teaching Dusk a few more skills.
“I’m not going to complain,” Dusk leaned back into the cushions as Cadence turned around, her ass now just over his widened eyes, “But wasn’t the point of this to show me that sex could be romantic? You have definitely proven me wrong.”
“So you want to stop?”
“No no no!” Dusk was stammering, excited by the idea of getting to go again.
“Good. I hate the idea of wasting magic helping you to recover faster if we weren’t going to use it.” Cadence lowered herself down, her head by Dusk’s crotch and vice versa. Dusk eyes were glued to the mare’s pussy as it got closer. “Besides,” the mare continued, “What I showed you is just the start. The real romance in sex comes when both ponies are sharing in the fun.”
“I see.” Dusk was barely listening, his mind focused on one thing. Cadence couldn’t blame the poor stallion. Still, this would be an important learning experience, not to mention fun for her too.
“You ready?”
“Yes, but, how do I…?”
“You’ll figure it out.” Cadence lowered herself down so that her pussy brushed against Dusk’s lips. The stallion’s eyes went wide as he stared at her dripping pussy. “Ponies learn best on the job, so to speak. So, give it a go.” Without waiting for Dusk to start, Cadence took the stallion into her mouth. His cock twitched instantly at the contact. He was already so excited to start again. Cadence smiled in spite of her full mouth and began to swirl her tongue around Dusk’s head. She could hear him moan at the feeling and it made her motivation that much stronger. She would make this cute stallion cum again and again.
Dusk took a moment to recover from Cadence resuming her skillful work with her tongue. After he had a chance to get his head back on straight, he turned his attention to the pussy inches from his face. Unsure of exactly what to do, Dusk poked his tongue out from his lips. He’d seen the diagrams of course, but as Cadence had proven to him, the real experience was far more personal than the textbooks had suggested. Still, the basics seemed to apply. He would just need to stimulate her as best he could.
He grabbed her butt on either side by the cheeks, lowering her down just enough for him to have the best access to her lower lips. He pressed his tongue in past her threshold, feeling her hips quivering at the touch. That seemed to Dusk like a good sign, so he moved his tongue around awkwardly.
With a flick of her tongue, Cadence sent a shiver of pleasure through Dusk’s body. It was starting to feel very good for her too. As she had thought, Dusk had no real idea of what he was doing beyond the basics, but he would get better, especially as fast as the stallion tended to learn. For now, his pleasure was her focus. She would let him figure out for himself how to handle a mare.
This was a lesson that Dusk took on with enthusiasm. His tongue explored her pussy, the stallion growing accustomed to the taste and feel of another pony’s most private area. It was incredibly exciting for him, and while he imagined he wasn’t very good at it, he could tell that Cadence was enjoying it anyway.
After swallowing Dusk’s cum earlier, Cadence had felt pent up, her body craving its own orgasm. So, as the stallion started to work her body, the pleasure was quick to build up inside of her. Cadence had started this as a lesson for Dusk Shine, but she now found herself hornier than she had been ready to be, her body already quivering in anticipation of the orgasm that she was going to experience. 
Dusk could feel, could taste that Cadence was turned on. Her pussy was growing more wet the more he awkwardly moved his tongue around. He remembered his textbooks, trying to think of what he could do to make the experience better for the mare that had been so nice as to give him this wonderful night. She was showing him a good time, and he was determined to give her everything he could in return. It was while he was thinking about his books that he remembered what he had read about the clitoris.
The taste of Dusk’s precum on her tongue was getting Cadence worked up. His next orgasm was getting close, and she would get to taste Dusk Shine’s cum while feeling him try to bring her to her own orgasm. Cadence grinned, looking forward to it. However, she was certain that she would beat him to the finish line. His body was beginning to tremble under her, his moans growing louder, even muffle as they were. He was getting close. However, any thought she had that he would orgasm before her vanished the moment she felt his rough tongue against her clit. 
“Oh, fuck!” It was probably the most unprincessly thing she could possibly have said in response to the stallion hitting his bullseye. From where his face was buried in her pussy, Dusk grinned at his victory. He immediately set to work on her clit while he began to play with her ass with his hooves. It was immensely pleasurable for Cadence to feel what his tongue was doing, but just feeling how into the experience the stallion was getting turned her on that much more. Now, especially as she realized how intent he was to make her cum, she was determined to do the same for him. She would give Dusk an oragasm so good he wouldn’t be able to think straight. 
So, both ponies put their hardest efforts into making the other cum. It was a battle between Cadence’s skill and Dusk’s advantage that Cadence had already built herself up while pleasuring him before. It was a battle Cadence was quickly losing. Her hips began to shake in Dusk’s grip as her pleasure rose. She was gasping and moaning around his dick, her whole body beginning to press down to give Dusk better access.
The stallion didn’t waste the opportunity. It was getting harder and harder for him to concentrate on pleasuring the mare as his own climax grew slowly closer, but he kept himself as focused as he could as his tongue worked her lips and clit. He could feel her orgasm coming, his mouth working more to give to her the wonderful gift she had given to him moments before. His wish was granted. 
After a few minutes of the two pleasuring the other, Dusk felt Cadence pull off of his cock. He whimpered in disappointment for a moment before realizing why Cadence had done that. The scream of pleasure she let out was deafening in the small library study. There was no possible way that the guards outside hadn’t heard it, but neither pony cared. The guards knew which ponies were the last ones in the building, and no city guard in their right mind would interrupt Cadence when she was fucking someone.
The mare’s body was shaking as she climaxed, cum gushing out over Dusk’s mouth, the stallion lapping it up as it came. His face was still going to be sticky after this was all over, but he kept the mess from being too bad, all while mimicking what Cadence had been so kind in doing for him. The mare quickly put her mouth back around Dusk’s cock. He had beaten her, but she was still determined to make him cum too. So, even as her orgasm was still rocking her body, Cadence got back to work on Dusk. She moaned at the last of her climax even as her tongue slid down his shaft again.
Feeling the wonderful touch of the mare’s tongue on his cock once again, Dusk leaned back and loudly moaned. Cadence thought for a moment about letting Dusk know that she didn’t need to recover either with time or with a spell the way that he did, but she stopped herself as she realized that he probably knew and was more focused on his own pleasure now that his own orgasm was mere seconds away. It was definitely only going to be a matter of seconds. 
Legs squirmed under her and his hips swayed slowly. Cadence held his hips still to give herself better control over how she handled his cock. Dusk was moaning louder as she doubled her efforts, using her mouth in ways that Dusk had never imagined being so wonderful even a short few minutes before. For Cadence, she was just surprised at how much she had missed the feeling of a cock in her mouth. She had always enjoyed pleasuring stallions this way. The small movements in their legs, the way their hooves would go to her head; it was all wonderful to her. Her favorite part though, was getting to take the lead completely. Every bit of pleasure the stallion felt was because of her, and it made the ending all the more satisfying to her. The cum she would taste in the end would be the sign of her victory.
Dusk was in a state of bliss that made it hard for him to even think about anything other than the wonderful, velvety feeling of Cadence’s mouth around his cock. The sounds she made, the slight noises as she worked him felt to Dusk like the most wonderful sounds in the world. While not in the way that he would ever have imagined it happening, a mare was showing him a good time, and all he had to do was lean back and let her do her thing. Listening to Cadence’s little muffled sounds and feeling her warm mouth around him, he felt so close to her that he didn’t have words to describe it.
After a few minutes of soft intimacy, Dusk began to feel his climax coming on. Cadence sensed it immediately. The gasps and moans that Dusk was making were getting louder and more pleading. He was so close, and she would get him there in the best way possible. Doubling her efforts again, Cadence got ready for his orgasm.
With one final yell, Dusk was thrown over his edge, his balls emptying into Cadence’s mouth. The mare was surprised at how much there was. Even with her spell to help him recover, Dusk should normally have been fairly drained of cum, but she felt it shoot into her mouth as much as it had the last time. The mare’s surprise did not stop her from being able to swallow every drop. Dusk thrust forward unconsciously at the feeling of the mare’s throat convulsing against his cock. She had hilted him in an effort to not waste a drop, and the immense pleasurable sensation of it all drove him mad.
Seconds passed before the stallion was finally done, Cadence pulling off of him with a wet plop. Exhausted, Dusk flopped back against the cushion and caught his breath. Cadence gently set herself down next to him. She was also trying to catch her breath; the stallion’s orgasm had lasted longer than she was used to from a stallion and she hadn’t been able to breath while she had him hilted. Cadence always felt delighted to make ponies cum, but there had been something especially wonderful about what she had just done. Perhaps it was how fond of Dusk she was, but making him cum had been second only to making Gleaming Shield scream with pleasure. As she recovered, Cadence made up her mind to keep going and to show Dusk just how wonderful it could be to have proper, intimate sex. 
The two ponies lay on the cushions and took a moment to soak in the glow of the experience. Cadence was the first to move, though only enough to sit up and look at the stallion. Her horn glowed pink again, and the stallion felt the same sensation as before coming over him. Then, his cock was back at attention once more.
“How much are you planning to do to me?” Dusk was both eager and baffled.
“Well, if my goal is to demonstrate the romance of sex,” Cadence rolled over so that she was on top of Dusk again, this time with her face inches from his, “Then I have to show you the main event.” Dusk’s expression lit up at the suggestion.
“You mean…,”
“Keep laying there like that. Let me get us started, then we can swap and you can take the lead. Sound good?” Dusk nodded eagerly. “Good. Now, get ready.”
Cadence straddled the prone stallion. His cock hard against his belly until her magic gently took hold of it. Carefully, Cadence lined it up with her, gauging mentally how deep it would go as she gently stroked Dusk off with her magic. It would be a snug fit, she realized to her delight. She lifted herself up just enough to line the cock up with her entrance. Then, she lowered herself back down, taking Dusk’s cock in slowly.
“Oh, Celestia!” Dusk whispered. His front hooves instinctively moved to grip her hips as he moaned quietly. Cadence finally hilted on the stallion’s cock, feeling it twitch inside of her. She bit her lip again, drinking in the sensation of being filled. It had been a while since she’d fucked a stallion. Once she was reacquainted with havin a cock inside of her, Cadence began to slowly rock her hips. 
“How does this feel?” She moved so that her face was hovering over his, her lips less than an inch from his own.
“This is amazing.” Dusk’s eyes were pools of emotion; excitement, lust, joy, and intimacy. Cadence closed the last gap between them and pressed her lips to Dusk’s. The stallion kissed her back, moaning softly as he did. Her hips gently swayed, taking it slowly. She couldn’t have him cumming just yet, she needed to build anticipation for what she knew would be his favorite part.
The two of them were pressed together on old cushions in a mostly forgotten section of the library. The room echoed with their soft moans and quiet gasps as Cadence gave Dusk the best first time she knew how to offer. His hooves felt her body up, the stallion delighting in the touch of their bodies, in the sensation of being joined with another. Cadence kissed Dusk again, his cock filling her as her tongue pressed back his lips. Dusk’s eyes were locked with hers, the two feeling closer in that moment that they ever had.
The mare rocked her hips faster, the sound of their bodies smacking against one another driving her to greater heights. It had been a while since she had gotten this into a sexual encounter with anyone besides Gleaming Shield. She moaned into the stallion's mouth again, her hooves barely holding herself in place as they started to shake from her building pleasure.
“Cadence!” Dusk beat her to the climax, but only by a few seconds. He thrust up into her, his back arching as his body tried on instinct to bury his cock as far in as it could go. Cadence could feel his warm cum shooting inside of her, filling her. A little bit of magic made it so that she wouldn’t need to worry about the consequences of that, and could just enjoy the sensation of Dusk’s cum filling her.
Dusk’s hips pressed into hers as she rocked slowly, milking every last drop of cum from his cock. The last bit of slowing motion was actually what finally pressed Cadence over her own limit. She had hoped to orgasm in time with the stallion, but instead, just as he was relaxing, Cadence screamed in pure bliss. She pressed herself into Dusk’s prone form, her legs wrapping under him as she used her leverage to slide herself down one last time, the stallion gasping at the overstimulation he felt. Cadence felt nothing but ecstasy, however. Her body trembled as her body was overwhelmed with the pleasure she felt. Her breathing was ragged and her body exhausted when the orgasm finally eased up. When she finally was able to open her eyes and looked down at Dusk, she found him staring at her in awe.
“What?” She asked with a slight, embarrassed smile.
“That was amazing,” Dusk said. Cadence turned to lay on her side, her hoof on her hip and a sultry smile on her face.
“The sex?” 
“Oh, definitely, but I meant…, watching you.”
“Oh?” Cadence ran her hoof along her body, watching as Dusk’s eyes tracked it.
“Y…Yeah. It was, well it was…,”
“Sensual?’
“Yeah.”
“It’s intimate to watch your partner cumming, isn’t it.”
“Yeah.”
“Romantic?” Cadence asked, teasingly. That made Dusk laugh.
“You more than made your point.”
“Are you saying I’m rubbing it in?”
“I’m not saying that.”
“Just thinking it?”
“Maybe a little.” The two of them laughed, Dusk’s laughter cutting off when he noticed Cadence’s horn glowing and felt the same sensation as before.
“Again?”
“Again.”
“How are we doing it this time? It seems like you really want me to experience sex in a bunch of different ways.”
“Of course I do,” Cadence replied, “A studious stallion like yourself should appreciate the value of a thorough education.” Both ponies laughed for a moment before falling silent, their faces getting close before both leaning forward for a kiss. Cadence was the one to break it off before rolling over so that she was on her belly. Then, she moved so that her butt was poking out into the air.
“What are you doing?” Dusk asked.
“Inviting you. I’ve shown you all I really want to. Now, I want you to have the chance to feel what it's like to take the lead. I’m here for you, so why don’t you take me for a ride?” Dusk looked at Cadence’s beautiful body, curvy in all the right places and with a beautiful shine to her fur. The mare’s pose was definitely inviting, and Dusk wasn’t going to say no to anything the mare suggested.
“Yes, please.” Dusk rose from the cushions and moved around Cadence so that he was in position. His cock lined up with her entrance, her soft butt squishing against his hips as he slowly pushed into her. Cadence purred pleasurably as she felt it happen. This was what she had been building to the entire time, the main event.
“I’m going to start moving now.”
“Enjoy yourself,” Cadence replied, turning her head to wink at the stallion. Dusk laughed nervously, then began to slowly rock his hips into her. Cadence lay with her forehooves curled under her head to give herself a little more comfort. She smiled to herself as she felt Dusk slowly pulling most of the way out of her before gently pushing back in. Dusk was taking things slowly, and she found it hopelessly adorable.
“This is amazing,” Dusk said. He pushed into her again, only barely faster than last time. However, the stallion did slowly find a rhythm that he liked. With gentle but deliberate thrusts, he slowly worked his way to fucking Cadence properly.
Cadence was in heaven. His cock filled her just the way that she liked it, and feeling him take it slowly further hit home for her that she was giving Dusk his first time, that she got to be the one to introduce the bookish stallion into her word of love and pleasure. For the princess of love, there could be no more wonderful sensation than the feeling of a pony’s first time being as wonderful as she could make it. She only wished that she got more opportunities to do it.
Dusk moaned as his cock buried itself inside Cadence once again, the stallion slowly growing in confidence and thrusting with more force. He was inexperienced and sloppy, but Dusk had energy and enthusiasm. Experience would come with time, and Cadence could help with that. The stallion thrust with more passion with every passing moment, moans and gasps escaping his mouth as he rode Cadence. His body lowered until it enveloped hers, pressing her head down onto the cushion even as her hips stayed raised in the air. Cadence moaned as she drank in the sensation of Dusk filling her, even as she struggled to keep her body where it needed to be.
“This feels so good.” Dusk gently nibbled on Cadence’s ear, his hips already shaking from the pleasure.
“It feels good for me too.” Cadence had an expression of bliss on her face. Dusk’s thrusts were wild and growing faster, the sounds of their hips slapping together filling the room. Cadence had always loved things rough, and she knew she wouldn’t last long like this.
“I’m glad,” Dusk said, “I want this to be good for you too.” The sounds of Cadence’s sexual bliss was heaven for the stallion. If there was any lingering doubt in his mind about if Cadence was right, they vanished there. Dusk realized that there was nothing in that moment that he wanted more than to make her cum, to her the pleasure in her voice and to know that he gave that to her. While Dusk never thought of the experience as romantic, given that Cadence was taken, he now saw how sex could be like that for a couple. Dusk had never experienced something so intimate as what he was doing in that moment, his body joined to another and her pleasure becoming his.
The mare beneath him was moaning louder and louder with every passing second, Dusk’s own voice growing in volume to match hers. Their interlocked bodies quivered as they felt the other’s warmth, the passion of Dusk’s wild thrusting carrying both of them towards their climax. Neither one wanted to be the first to orgasm, and as Cadence felt Dusk’s thrusts grow more uneven right in time with the building of her own climax, she realized that it would be close. She bit the cushion under her as she loudly moaned, driving Dusk on further.
The small room echoed with the sounds of slapping flesh and youthful moans. Cadence could smell the old dust and made a mental note to find someplace nicer for her next time with Dusk, but for the moment, she found she didn’t care. The cock pounding into her made it difficult to think about anything else.
Dusk pressed himself into Cadence even more. He needed to feel her body against his. His moans were cutting out, the stallion unable to make any sound other than ragged breathing as his climax finally came to him. With a final, firm thrust into Cadence, he finally came. His cum shot into her, his cock buried balls deep inside of her. Cadence moved her own hips against Dusk’s as best as her limited position would let her, riding out the last of her own buildup, ensuring that they climaxed together. Hers started a second after his, but both of them climaxed with the other. Unlike Dusk, Cadence had not lost her voice to the pleasure. It was the exact opposite for her. The mare let out a long, loud yell. She tried to muffle it with the cushions, but it still filled the room and could likely be heard from outside. The mare didn’t feel an ounce of embarrassment thinking about that, instead just allowing herself to drink in the wonderful feelings that coursed through her body.
After a few seconds, the two of them were finally done with their respective climaxes. Exhausted, they both flopped down onto the cushions, Cadence still underneath Dusk. It took both of them several seconds to recover. Dusk had never felt anything as pleasurable as the orgasm that had just finished, and Cadence hadn’t in a while.
The two of them were left panting on the cushions. Cadence was pressed down by the weight of the stallion above her. She squeezed herself out from under him and rolled over onto her back. Cum filled her, and she found she’d missed that feeling. With a quick bit of magic, she ensured that nothing would come of that. Getting pregnant from her girlfriend’s brother wouldn’t be a good look for a princess. 
The stallion next to her was clearly exhausted, and with multiple orgasms across a relatively small amount of time, that made sense. Cadence adored her love-recovery magic, but it certainly took a toll on whatever stallion she used it on. Still, from the big grin on Dusk’s face, her mission was accomplished. Rolling back over so that she could face the stallion, Cadence traced her hoof down his chest.
“So, how was that?”
“That was the best experience of my life!” Dusk panted.
“Good.” Cadence leaned over and kissed his cheek before bringing her lips to his ear one more time. “So, still think there’s no romance to sex?”
“Oh, absolutely not!” Dusk had goosebumps as he suddenly stood up. “Everything I thought I knew about sexual intercorse was completely wrong. I can’t believe I had such a simplistic view on it.”
“That’s great, I’m glad you….”
“I mean, there is so much more to it than I could have guessed, and I’m betting I’ve only scratched the surface. Right?”
“Well, yes….”
“Yes!” Dusk was pacing now. It was a familiar sight to Cadence by now, and she figured she knew exactly where this was going.
“Need to do some more studying?”
“Oh, I certainly do! I’ll need a willing assistant for it of course. That, or I might be able to find books that actually do cover this side of things.”
“I think you mean porn, and I can provide you with some recommendations if you like.” Cadence rolled her eyes at Dusk doing his usual thing and getting incredibly into a new subject after finding it. She hadn’t really expected him to have that reaction to sex, but she wasn’t going to complain about it. It wasn’t quite what she had been trying for, but Dusk’s newfound enthusiasm was close enough for her. Still, there were more lessons to teach.
“So, what do we do now?” Dusk looked eager but exhausted. Cadence was feeling it herself. For a moment she considered using her spell one more time to recharge the stallion and go for another round, but she wasn’t sure she even had the energy for the spell.
“Well, for now I suggest we go to bed.” Cadence straightened her hair and walked towards the door. Dusk Shine was visibly disappointed, which Cadence took as a compliment.
“Really? I was kinda hoping….”
“For another round? Not tonight.” Cadence opened the door and stepped out, pausing for a moment at the threshold. “Don’t think this means we are done though. We’ll have another lesson soon. So, study up,” she said with a wink before closing the door. Dusk grinned excitedly as he put the cushions away. They would need to be cleaned later, but he would do that carefully at the end of the night. Being caught with a cum stained library cushion wasn’t something he was looking forward to. However, he was looking forward to whatever Cadence would have in store for him the next time that they ‘studied.’ As he grabbed his things and prepared to leave for his tower, he found his mind wandering. Dusk Shine had never been more happy to be proven wrong about something in his entire life, and thinking about the feeling of Cadence’s body against his, he couldn’t wait for her to school him again.
