Silverstream's Substitute Tutor

by Holocron

First published

Silverstream's regular tutor couldn't meet her, so instead, Twilight sends Spike to look after her.

Since Big Mac became her tutor, Silverstream's grades have gotten much, much better. And though Twilight Sparkle has asked if the hippogriff was ready to go without a tutor, she refuses. Not really for the grades, but for the body shaking sex the stallion gives her whenever they meet; though this is a major secret. Unfortunately, her tutor now has to leave for Appleloosa for the week, and she is really, really horny. Concerned that the lack of Big Mac may affect Silverstream's grades, Twilight has asked someone else to fill in for the time being; Spike the Dragon.

How to Help her Grades

Pacing back and forth in frustration, Silverstream was in her dormitory room. When she was told Big Mac was going to
Appleloosa, she was annoyed. That would mean no magnificent cock for a week. But then when Headmare Twilight told her she would have a substitute tutor, she felt a little better. Only to then be discouraged when she was told it was Spike. Sure, he was a dragon, and that should mean something, but she has had conversations with Smolder about such things. Should the dragoness has said some dragons can get pretty big, with cocks that could stretch even the most flexible holes, Spike had only just come of age, and his greed and lust were lower than average for a dragon. He could get big one day, but not any time soon.

Pacing some more, Silverstream looked over to the other bed in the room. Ocellus' bed, but it was empty. The changedling was out with Smolder tonight. The hippogriff only huffed in frustration as she was envious of those two. It wasn't really a secret that both dragoness and changedling were fucking, and more than once, Silverstream was curious what it was like. Given her shapeshifting nature, there were no doubts Ocellus could have any cock she wanted between her legs. Envy bubbled in the hippogriff's mind, only being interrupted by the sound of knocking at her door.

Giving one last sigh, Silverstream walked over to the door. Opening it, she saw Spike standing there. Sure, he had just come of age, as Smolder said, but was nearly a head shorter. More than once, she's had to remind herself that dragons grow based on their greed, and Spike was the most selfless dragon in Equestria. He was dressed in some dress pants, and a button up shirt, no doubt something he thinks Rarity would like. His crush on her wasn't a secret, but it was debated in whispers if Rarity knew or cared. She was nice, but could be quite vain when she gets attention.

"Hello Spike, please, come in." Silverstream commented, gesturing her arm. "Please, come in."

"Thanks, Silverstream." Spike nodded, walking into the room. Under his arms were a number of books. "So what should we work on-ah?!" Turning around, he saw that not only did Silverstream close and lock the door behind her, but she had already begun to unbutton her shirt. "W-w-w-w-what are you doing?"

"Look, I'm gonna get to the point." Silverstream commented, looking at Spike, while dropping her shirt and skirt, leaving only her thong and tight looking bra. "You're a sweet dragon, and I know you were forced into this. So I'm gonna make you a deal." Spike only stared on as the hippogriff further stripped, showing off her wet pussy and huge tits with perky nipples. "I study best after I've fucked, and I mean a bed shaking, womb stuffing fuck. So how's about we just get on the bed, and you help me study?"

Spike stared for a moment, his eyes were unable to look away from Silverstream's tits. How perfect they were, how big and perky they were. It reminded him of the time he accidentally walked in on Fluttershy after she had showered. But when he saw her, he felt something growing inside him. It was warm, but grew hotter and hotter as he could feel his body starting to get sore. His breath became heavy as he could feel his clothes getting tighter on him.

"Um...Spike...are you o-" Silverstream asked, but she could only watch as this smaller dragon was growing in size. But not only his muscles, but something else between his legs was growing. "Well...okay, I didn't expect that."

Cautiously, she approached the dragon, who was only huffing a hotter and hotter breath. Though he didn't seem to be hostile, Silverstream still felt some overwhelming feeling. Her body was also becoming hotter and more aroused. Swallowing hard, she reached out to touch his metal like scales and muscles. He was so hard, and the cock that was tearing out of his pants. Even when it wasn't fully out, she could tell he must be massive.

"Well...looks like Smolder was wrong about you." Silverstream cooed, shuddering as she could feel how hot Spike was. "Then maybe you can help me after all."

Rubbing her hand along Spike's chest, she swayed her way over to her bed. Once there, she bent over it, wiggling her ass back and forth in front of the dragon. His hot breath and throbbing cock was showing off more and more of his growing lust. Silverstream felt as her pussy was getting wetter and wetter. Was he going to fuck her full and hard then and there? Maybe use that large mouth to tongue fuck her first? Or maybe he was going to place those big, strong claws on her first, and fuck her like the cock loving whore she was?

"Come on Spike..." Silverstream cooed, looking over to the dragon with heart filled, fluttering eyes. "Please, don't keep me waiting." Spike smirked.


"Wow, you're just as good as Big Mac is at tutoring Silverstream." Twilight complimented, reading through some of the hippogriff's current grades. "How did you do it?"

"Oh well...you know..." Spike nervously replied, rubbing the back of his head. He couldn't even look the mare in the eyes as he explained himself. "I just saw what she needed, and found a way to help her. J-just like you've told me."

"Oh, good, good." Twilight nodded, smiling at the dragon. "Well, I did get a call from Applejack, and she said both her and Big Mac will be in Appleloosa for maybe another week. Would you be able to continue tutoring Silverstream for the time being?"

"I-I-I-I..." Spike replied, his mind filling with what he had done with Silversteam, as well as what she was going to do with him next. Swallowing hard, he feign confidence with a smile on his face. "S-sure. I can handle it."
