#14 of Teaching Blueblood

Vinyl shows Octavia that the recent changes to her body aren't all bad, but the unicorn is in for a real shock when she tries out the new equipment.


"The good news is that this sort of thing has happened before. You aren't in any danger." The doctor looked over some medical charts while Octavia and Vinyl waited anxiously to hear his diagnoses. "Vitality transfers aren't normally dangerous, so they're unregulated. Sometimes a unicorn will drain a stallion and transfer it to a mare. It's usually just a party gag or something equally harmless, and it never results in something quite so...blatant."

Octavia shifted in the hospital chair. Her new equipment rubbed against the insides of her thighs, and the alien sensations made her wince. Vinyl held one of her hooves for support. "Will she go back to normal?" the unicorn asked.

"I can't say for certain," the doctor said with a regretful sigh. "Everypony responds to magic a little differently. Vitality transfers are usually temporary, but this is a very powerful spell." He looked at Vinyl sadly. "I can already see the spell matrix fading away."

Octavia glanced at Vinyl, who was covering her mouth with a hoof in shock. "What does that mean?" she asked.

"It means the spell is finished," Vinyl said. "Once the spell matrix fades away completely, it can't be undone. The magic becomes part of you. I...I think you might be stuck like this." Octavia whimpered and crossed her legs, uncomfortable with the new additions to her body.

"It isn't as bad as you might think," the doctor said, a hint of optimism returning to his voice. "As I said, I've seen this spell used in similar ways before. There's a quick and easy way to let a mare hide the changes, but it's only intended for temporary use. Try these." He levitated a small box out of a cabinet and let Octavia open it.

The cellist held up a pair of dark grey panties, her blank stare never leaving the doctor. "You'd better be joking." When he shook his head, she reluctantly began slipping them on.

"They're only good for one day," the doctor said. "After that, the spell needs to be renewed. I can teach it to your friend, if that would help."

Octavia slid the panties up her legs and squeezed her new endowment into them. She didn't feel any different, although the soft fabric against her sheathe felt quite nice. "Hey, cool!" Vinyl exclaimed. Octavia looked between her legs and saw that her new stallionhood had completely disappeared. The panties had vanished as well, leaving no indication at all that anything was out of the ordinary.

"I can still feel it," Octavia complained. She walked around the room once to see how it felt. "It's...painful. Why does it hurt?"

"Your body is still getting used to having nerves where it didn't before. The tenderness will go away in a few days."

"But I want to get rid of it!" Octavia insisted. "Please, doctor? Isn't there some kind of surgery or a different spell we can use?"

After looking over them one last time, the doctor dropped the medical charts into a sealed container. "I'm afraid not," he said. "Magical intervention is right out. I haven't seen spell work this powerful in a long time, and it could be dangerous for everypony involved if we try to mess with it. I wouldn't want to risk surgery either, or you could trigger some hidden counter-curse. It's up to you, but something with this much power behind it usually has some very intricate safeguards in place in case anypony tries to fiddle with it. I'm sorry, Octavia, but as your doctor I have to recommend that you learn to live with it. It's the only safe thing to do."

Octavia crossed her legs and stared at the floor, looking as though she would burst into tears at any moment. Vinyl hugged her tightly, and she buried her face in the comforting warmth of the unicorn's white coat.


There was something to be said for waking up next to somepony. Octavia was still getting used to it, but she enjoyed the feeling of being held in her sleep. Vinyl was a rowdy party animal most of the time, but in spite of her frantic activities during the day - or perhaps _because _of them - she slept like the dead. Nights had never been more restful.

Unfortunately, mornings were not as pleasant as they had once been. It had been two weeks since her sudden transformation, and Octavia still hated the way her body felt. Every morning there was a tightness in her groin, and a great temptation to touch it.

She always refrained from doing so. She had tried once, and found it...uncomfortable.

It wasn't long before Vinyl stirred. "Morning," Octavia whispered.

"Mmmm" was all that Vinyl could manage. She kissed her cellist and snuggled closer under the covers. Octavia tried to pull away, shrinking from any contact that might stimulate her.

Soft fur brushed against her erect shaft, and Octavia whimpered. Vinyl hugged her closer, ignoring her quiet protests. "You're alright," she whispered while Octavia tried to hide her blush. "It's okay, Octy."

In the beginning, Octavia had been afraid that her special somepony wouldn't want her now that she was a freak. The thought of losing Vinyl so soon after finally having her was heartbreaking, and it took a lot of reassuring to convince her that their relationship wasn't going to end.

In fact, if she weren't so distracted by her new equipment, Octavia would have been very impressed with how Vinyl handled her problem. Her marefriend had been very patient with her, never once trying to pressure her into sex. It was strange to see the normally manic pony being so cautious and considerate. It was a side of her that few ponies ever got to see, and Octavia secretly cherished that.

"We could fool around if you want," Vinyl offered.

"I don't think that's a good idea," Octavia said. "I'm not...comfortable."

"I know," Vinyl said with a sigh. "I don't blame you." She kissed Octavia's nose in what had become something of a morning ritual. "Just letting you know the offer still stands. Don't rush yourself, babe."

A small, almost nonexistent whisper came out unbidden: "I had an idea." Octavia regretted saying it as soon as the words left her mouth, but she had already committed herself. "M-Maybe if I...if I couldn't see..."

"You think that would help?" Vinyl asked. "Hey, no harm in trying. I think I've got just the thing." Her horn glowed, and a white scarf floated out of her closet. "My mom gave me this a while ago. I didn't have a use for it until now." The length of soft fabric wrapped around Octavia's eyes, blinding her. "How's that?"

Octavia started to say that she didn't think this was a good idea anymore, but Vinyl's hoof brushed against her shaft and her protests died in her throat. She had avoided playing with her new stallionhood all this time, and it was extremely sensitive. She slowly spread her legs, still debating whether or not she should back out while she had the chance.

"I'll start slow," Vinyl said as she slid beneath the covers. "Try to relax, okay? Don't freak out on me."

"Of course," Octavia thought sarcastically. "Who would ever freak out about growing extra reproductive organs?" Vinyl pushed her onto her back and laid down between her legs. An awkward minute passed while she waited for something to happen.

Vinyl hadn't told Octavia, but she had been dreaming of this moment. She had wanted a closer look at for days, and was enjoying the opportunity to look it over. Octavia's new stallionhood was grey and purple, just like the rest of her. it started out purple at the tip, but the shaft abruptly faded to dark black near the medial ring. "You're actually really big down here," she said as her hooves went to work once again. "I don't normally go for stallions, but the few I've been with weren't nearly this hefty. How does it feel?"

For a moment she was afraid to answer. "Could we start with something more familiar?" Octavia asked. Vinyl stopped what she was doing and carefully slid her hoof downward until she was touching Octavia's pussy, hidden behind her fuzzy foal makers. "Better?" she asked.

Octavia couldn't answer. Shame and embarrassment had robbed her of her voice. "Told you to relax," Vinyl whispered. Hot breath tickled her, and Octavia felt the unicorn's muzzle slide below her balls moments before a hot, wet tongue snaked inside of her. Her mouth fell open in shock at how incredibly long it was. That couldn't possibly be normal!

"H-Holy Celestia!" she whimpered as she rested her hooves on the back of Vinyl's head. They were trying to keep things a little quieter than last time, as the neighbors had complained about the noise.

Vinyl went deeper, pushing the front of her muzzle into Octavia's tight muff. Her tongue lapped up her marefriend's juices, coating the inside of her mouth with the taste of Octavia's arousal.

After only a few minutes Octavia let out a muffled cry and pushed down on the back of Vinyl's head. She came hard, her pussy clamping down while her cock throbbed in sympathy. Vinyl's muffled giggle reached her ears, but the unicorn didn't let her amusement distract her. She hungrily lapped at Octavia's folds, drawing out the orgasm for as long as she could.

When it was over, Vinyl pulled back and licked her lips. "Damn, Octy. I think you needed this even more than me!" She slowly stroked Octavia's shaft with one hoof. "How do you feel? Any better?"

"I-I...think so." Octavia nibbled anxiously on one of her hooves. Her stallionhood was so hard that it ached, but she didn't dare say anything about it. "That was lovely," she said. "Thank you, Vinyl."

Vinyl kissed her on the cheek and giggled. "You should have seen your face," she said. "You had your tongue hanging out and everything. What I wouldn't give for a picture of that!"

Octavia was still trying to think of a witty reply when something warm and wet pressed against her stallonhood. Vinyl's hot breath tickled her cheek and made her giggle as she unicorn ground against her. "You want more, don't you?" she asked. Octavia hesitated, but nodded in agreement. "There's that blush again. Ready?"

"I think so," Octavia said.

Vinyl's hooves gently pulled the makeshift blindfold from her marefriend's face. After a reassuring kiss, she shifted so that the tip was prodding her entrance. Octavia's blunt head spread the unicorn open, and the first inch squeezed inside. It was a tight fit, but Vinyl wouldn't be denied. She breathed evenly as she dropped lower and lower, soon taking in all but the last few inches of Octavia's new stallionhood.

After a little more work, she finally bottomed out. Octavia throbbed inside of her, and they both took a moment to catch their breath. "Damn," Vinyl groaned. "You've got a big dick for a mare." She laughed as Octavia glared at her. "What? I'm serious. That's got to be, like, a foot and a half at least."

"H-Hardly," Octavia said.

Vinyl ground against her base, cutting off any further argument. "Still really big," she grunted as she lifted her hips. Her wet, aching pussy quivered at the sudden feeling of emptiness. Octavia grabbed her shoulders tightly and clung to her as she dropped down again.

The thrust into Vinyl's depths felt maddeningly good. Octavia bucked upward with a brief shout and caught her lover by surprise. "Shh," Vinyl whispered. The neighbors had complained about the noise after their previous session. "Keep it down, baby." She picked up the pace, sitting up on the earth pony's lap for a better look at her shy marefriend.

They continued that way for a long time, moving in synch they tried to get used to a multitude of new and strange sensations. Soon Vinyl whispered that she was getting close, and Octavia redoubled her efforts. She felt bad that her marefriend hadn't been getting the attention that she deserved lately, and wanted to make up for it now.

Octavia thrust upward with a little more force each time, causing Vinyl's moaning to rise in pitch. She began to feel an odd tingle along the length of her stallionhood, and grunted as something in her groin pulsed. Vinyl's eyes widened as she gasped. "W-What was that!?" she asked.

Before Octavia could answer, it happened again. Vinyl clenched her teeth as a ripple of solar energy surged through her, lighting up her horn like a tree on Hearth's Warming Eve. She came harder than she had ever cum in her life, and the effort of keeping quiet was almost too much for her. She still squealed happily, but kept it low enough that it wouldn't bother anypony next door.

After a moment of stunned silence, Vinyl started to say something. She was cut off when Octavia rolled them both over and took control, forcing the DJ into a needy kiss. "Not done yet?" Vinyl asked when she was allowed to breathe again.

"It's hard to know if I'm getting close," Octavia grunted. "I don't exactly have a lot of experience with this sort of thing." She railed Vinyl mercilessly, causing the overly stimulated mare to squirm beneath her. It wasn't long before Vinyl was warning her of another orgasm, and Octavia made sure to sink herself in as deeply as possible for that one as well.

Again, her member emitted the strange magical pulses. Vinyl's body was flooded with solar magic, causing an orgasm so intense that her eyes rolled back in her head. This time Octavia kissed her, and the resulting scream was properly muffled. Despite how good it felt, Octavia's satisfaction remained frustratingly out of reach.

Both of them soon lost track of time. Vinyl came again and again, losing all semblance of composure. Rational thought became impossible as Octavia ravaged her. She gave up on communicating with words, and soon could only whimper and moan like a mare in heat. It was a good thing that she wasn't, because in her state she wouldn't have had the presence of mind to say anything.

It was a huge relief when Octavia finally felt like she was getting close. She had started to wonder if her endurance would ever run out. Her legs ached, her coat glistened with sweat, and she had given Vinyl several love bites hard enough to leave a mark. She hated to think what could have happened if she had been the one on the receiving end of such treatment, as her reputation would likely have been irrevocably tarnished. On Vinyl, it just looked like the end result of another successful party.

Vinyl, meanwhile, wasn't capable of thinking much of anything by this point. Her mind had been blown so many times that there wasn't much of it left.

"I-I think I'm cunning!" Octavia hissed. "Oh, goddesses! D-Do I pull out?" Vinyl's hind legs wrapped around her in a vice-like grip, which was as close as the unicorn could come to saying "no". She wasn't allowed to pull out, and Vinyl was making sure that she knew it. She buried her face in her lover's colorful mane and, at long last, hit her climax. Vinyl felt another surge of magic as she came, this one even stronger than the rest, and wondered how much of her sanity would be left after this.

Both mares screamed, no longer caring that the neighbors would hear. Octavia's head flared and locked them together as she strained forward, desperate to penetrate as deep as possible. She felt a wonderful rush as her foal makers began to empty themselves, an unfamiliar sensation that she instantly fell in love with. A rush of solar magic jolted both of them, causing Vinyl to go completely limp.

Octavia came harder than any stallion Vinyl had ever known, splashing up against her cervix and even straining against that final barrier. Her reserves seemed endless, and the pressure became so great that Octavia's flare wasn't enough to contain it. Her first male orgasm was more than she could handle, and the normally reserved musician completely lost control of herself. She bucked her hips and thrust wildly, giving up on any sort of rhythm for raw, animal lust. Vinyl mindlessly pushed back against her, driven mad with pleasure. Gushes of thick, white seed stained the bed sheets and Octavia's fur.

Vinyl collapsed, and Octavia landed on top of her. The unicorn stayed limp, unable to do anything more than mindlessly drool into her pillow as Octavia rolled them onto their sides.

Slowly, they both began to recover. Vinyl curled up against Octavia again and kissed at her neck, too tired to reach for anything else. Her first attempt at speech was a failure, so she waited a few minutes before trying again. "Mmmmmm..." There, that was better. Much more eloquent.

"Likewise," Octavia mumbled sleepily. "I'm glad you enjoyed it. I was s-scared that you'd...I love you, Vinyl."

"Love you too," Vinyl answered. She was completely drained, and decided that Octavia had the right idea: more sleep was definitely in order. She hugged her marefriend, buried her face in Octavia's fuzzy coat much like she did every night, and immediately fell asleep.


Once again, Terrabutt to the rescue. Dat DJ butt. If you're having trouble with the source like I am, try this one. I almost used THIS incredible bit of work from Derpah, but it didn't have the "come hither" look.

I'm really, really sorry that this took so long. I've been so busy with other things that this just fell off the checklist somehow. Anyway, hope you enjoy Vinyl having her mind blown over and over again. Let me know what you think in the comments, kay? By the way, that neat trick with the solar magic? We'll be seeing that again coming from the source. This was just a side effect of the magic making Octavia grow a totally new organ instead of improving what a stallion would normally have. It duplicated Celestia's organ, including the color pattern! Silly Blueblood, why did you try that spell on a mare?
