"What'd you think, Spike? Pretty cool party, huh?"

"Are you kidding? A holiday where you get free stuff? Best holiday ever!"

Twilight quit putting all of her presents away for a moment and turned towards Spike.

"Spike, it's supposed to be mutual..."

"Aw, come on! It's not like you pay me, anyways. How am I supposed to get enough bits for that kind of stuff?"

"I-" Twilight stopped herself once she realized that Spike actually had a point. "Never mind."

Conversation stopped between the two for a moment while Spike helped Twilight clean up the living room. She didn't consider putting some sort of sheet below the tree, so she had to deal with sweeping up all of the tiny pine needles from the floor. However, her magic made it a much simpler task than it would've been otherwise. Spike took the liberty of lounging on the couch after making sure that all of the presents were tucked neatly in the storage closet.

"Oh, by the way. Did you see that bruise on Vinyl's leg?" Spike said as he scratched his belly.

"Actually, yes. I did." Twilight answered with a troubled tone in her voice.

"You don't think... Alex is... You know..."

"Goodness! Of course not, Spike! Alex would never do something like that! Plus, Octavia would say something if that was happening... She's not the kind of pony that would let something like domestic abuse go unpunished, especially towards her best friend."

"Okay, okay. I was just wonderin'."

A few more moments of silence went by as Twilight dumped all of the tree needles into the trash bin.

"So, what do you think it is?" Spike sat up and puzzled while rubbing his chin.

"Well, it looked like a bruise... There's only one other thing I've seen that sort of mark from and I really hope it's not that..."

"Huh? What's that?"

Twilight paused and thought for a moment whilst running a few possibilities in her head.

"Don't worry about it. There's no way Vinyl would get something like that unless she took weekly trips into the Everfree Forest, which I doubt she does since she lives so far away from it. That's something she wouldn't do since she stays inside most of the day. Or, at least, that's what Alex tells me about her. It's probably just a bruise."

It sounded to Spike that she was trying to convince herself instead of trying to convince him, but she suddenly sounded confident again when she said that it was just a bruise, so he let the subject slide.

Just before Twilight walked up to her bedroom, Spike saw Twilight grab a book from a low shelf. She did it in a way that made Spike think she didn't want him to see her doing so. He didn't have time to read the entire title, but he could make out the first couple of words.

Everfree Forest.

Your heart rate was already fast, but it got worse once Vinyl told you about the spell she found. You were more excited and turned on than anything, but you now felt some nervousness as well.

"S- So it's not permanent, right?"

"Yup. Only lasts twenty-four hours. That's plenty of time for us..." Vinyl said in her best seductive voice, her eyelashes fluttering in your direction.

"So... That means..." You were beginning to stutter. "It's okay to cum inside you?"

"Mhmm. All you want. All... Night... Long..." She lifted a hoof up and scratched your chin seductively. You gulped and bit your lip.

She leaned back on the bed and looked down at herself after taking a quick glance at the instructions in the spell book. You were still a little scared that she might permanently damage herself, but you tried your best to put faith in her magic ability.

Her horn began to glow and her magic aura traveled down her belly until it reached right above her crotch. Vinyl's eyes closed so that she could concentrate and, since you didn't want your marefriend to be childless for the rest of her life, you kept quiet and did your best not to distract her as she did so.

"Okay. All done..."

You blinked in surprise. "W- What? That's it?"

Vinyl giggled. "Yup. Now, come here you stud..."

Before you knew it, she was down on the floor stroking your thick meaty cock. The familiar tingling sensation grew in your lower belly. You looked down with one eye closed to see Vinyl's gorgeous face below your shaft before her tongue dragged along the bottom of it. Your stallion cock twitched in pleasure and you bit your lip. The warm soft feeling of her tongue made you groan a little and you started to leak out pre-cum once her tongue began to play with your head.

"Mmmm... Somepony's excited..." Vinyl said before popping your head into her mouth and licking off your pre-cum.

"Fuck..." You reached down and played with her long bangs.

"Lets see how much I can take in this time..." Vinyl popped your head into her mouth once more and you felt her tongue swirl around it.

A low pleasure-filled groan escaped your throat as she began to take you further into her mouth. Her tongue was pressed to her bottom lip and she slid along the bottom of your thick shaft. Her mouth was extremely warm on the inside and you prepared yourself to enter her throat. Instead, she sucked back and played with your head once more.

Her second try was much better. Just like before, she slid you into her mouth. Vinyl moaned as the tip of her nose made its way farther down your cock and you felt a jolt of pleasure when her tongue passed over the ring on your shaft that marked the halfway point. She stayed there for a few seconds and savored the taste of your dick. You could feel the back of her mouth and you knew that one more inch would make you enter her throat.

She slid back and pulled you out of her mouth, gasping for air once the tip exited. Her eyes were completely filled with lust and she couldn't take her eyes off of your enormous horse cock.

"Much bette- Ahhh!"

You were cut off by her suddenly going down on you again. She slid down faster this time and before you knew it, her throat was squeezing your head and her chin was pressing against your balls. As she pulled back and began her sucking motions, thick drops of saliva trickled down your shaft and rolled over your balls. Lewd slurping sounds filled the room as your marefriend gave you the best head you ever received. Involuntarily, your hips moved back and forth in sync with her sucking.

"Sweet Luna, Vinyl... Ahhh! That feels amazing..."

Vinyl raised a hoof up to stroke the base of your cock as she continued to suck on it like a whore. You knew you couldn't take much more but you could tell that you'd be able to cum at least one more time after this. Her teeth lightly touched your shaft every so often but it didn't ruin the experience whatsoever. You couldn't blame her either; she was taking a cock that was almost thicker than her leg.

"Vinyl I'm gonna cum... I'm gonna cum, babe..." You spoke low through your moaning and closed your eyes as pressure built up in your abdomen.

Vinyl slid back on your cock and just sucked the first two or three inches of it while her hoof did the rest of the work, stroking hard and fast as you throbbed and twitched. It was obvious that she wanted you to blow your load inside her mouth, so you didn't hesitate to do so.

"Hnnnggg!" You grunted.

Your orgasm hit hard and caused your legs to twitch. You pumped ounce after ounce of thick creamy semen into her mouth as Vinyl's tongue continued to swirl around your head. Her hoof was still stroking you back and forth, attempting to milk every drop from you.

Vinyl moaned as she attempted to swallow your load, but some of your cum still managed to leak out of the sides of her mouth. Slowly, while still sucking on your cock, she took you out and caught her breath again. She took a moment to swallow what was left in her mouth and then licked her lips.

"Mmmm... You've been eating a lot of fruit haven't you?" She asked while looking up at you with her drop-dead gorgeous maroon eyes.

"H- Huh?" You were still catching your breath from your orgasm.

"Never mind." She got up and laid back down on the bed. "Your turn, lover boy. Take me however you want..." Vinyl held a seductive pose which left her soaking wet outer lips exposed through her rump cheeks as she presented her rear to you. Her muzzle was pressed into the bed sheets, but her eyes still turned back to look at you expectantly along with a naughty smile.

You felt a bit of blood trickle down your nose.

Spike knew he wasn't supposed to interrupt Twilight during her studying especially since she took the time to lock her door to her room to do so in this particular instance. Still, his curiosity got the better of him and he knocked on her door three times before preemptively flinching for a scolding.

Instead, in a low and uninterested tone, she answered. "Come in."

"It's locked, Twi."

It wasn't as if Spike could reach the door knob to check to see if it was locked. He simply assumed that it was since Twilight wouldn't have any other reason for closing her door all the way.

He heard a small sigh from inside followed by soft hoof steps on carpet. The door opened and the busy princess immediately turned back to her books which she temporarily abandoned on her bed.

"What'cha studyin'?" Spike asked as he hesitantly entered Twilight's room.

"Nothing." Twilight said nonchalantly. Her eyes were already focused onto her next book and she seemed as if she was worrying about something in particular.

Spike, Twilight's best friend, couldn't let that feeling go.

"Twilight. I can tell when you're worrying about something. Tell me whats up."

Twilight took a moment to think whether or not to tell him, but her friendship values eventually won out.

She sighed. "I'm worried about Vinyl. That bruise we talked about earlier... It might not be just a bruise."

"What'cha mean?" Spike hopped up onto her bed.

"Well..." Twilight flipped through some pages. "There's this fungus called 'Mors Moss' that grows in the Everfree forest that's been known to cause symptoms like that."

Spike scoffed. "What could something like that do? It's not like her skin's melting off."

"Spike, according to what I'm reading, if she doesn't get that treated soon..." Twilight's pupils dashed left and right as she scanned through text.

"Then what? She'll catch a cold?" Spike seemed as optimistic yet ignorant as always.

"No, Spike! Out of all the recorded afflictions associated with that fungus, eight out of ten ponies died within a week! What's worse, there's absolutely zero symptoms except for that bruise!"

"So, what are you saying is..." Spike's face contorted into fear as he suddenly realized the weight of the situation.

"I'm saying that if she doesn't get that treated soon, she could die!"

"Damn, Alex... Ahh!" Vinyl yelled out in surprise and excitement as you pinned her against the wall and rubbed your cock in between her ass cheeks. "I didn't know you were that horny..."

"You're the one teasing me..." The tip of your penis slid in between her cheeks and prodded at her warm marehood. "Your fault."

Vinyl let out an adorable moan as her forehead rested on the wall. Her entire body was shaking from excitement and desire.

"S-Stick it in already, dumb ass..."

You looked down to see that her juices were starting to dampen the upper portions of her stockings and you concluded that her body desperately needed to be fucked, so you did as she said and popped your head inside of her. It wasn't as if you could've resisted otherwise.

"Ahhhhn!" Vinyl moaned. It became apparent in that moment that she was extremely sensitive because of her being turned on so much.

You didn't waste a second. Your hips gently pushed forward and you felt her marehood constrict around your shaft. You had to bite your lip again to cope with the unbearable pleasure that came from penetrating such a tight and hot pussy.

Before you knew it, you could feel your balls mashing into her crotch and your base sliding inside. At the end of your lengthy dick, you felt her womb tighten around you and it urged you to start fucking the daylights out of her, but you gave her a moment to acclimate to you first.

She didn't, however, show as much restraint as you expected.

"Damnit, Alex! Buck me!" Vinyl reached back and spread her plot so you could enter her easier.

She didn't need to ask you twice. In one fluid motion, your hips swung back and plowed into her which caused her to let out another loud moan against the wall she was being fucked into. Again, you would've waited for her to get used to it, but because of how desperate she sounded, you didn't hold back. You obeyed your body's instinct and bucked her at a moderate yet forceful pace as you felt her warm fluids leak down your cock. In addition, her juices were beginning to dampen your fur and mat it down.

Vinyl's body rose up against the wall every time you thrust yourself into her. Her tail, even though you doubted she had control of it at the time, tried to wrap around your body in a futile attempt to hold on to something.

At that point, you were beginning to lose it. Vinyl's tight cunt was like a drug and you couldn't last long without it taking over your mind and driving you insane. You slid your meat out of her which lead to her yelping once the wide flared head popped out.

She was about to protest you stopping, but you didn't give her the time. You took her by her hooves and pulled her towards the bed with your lust driving your strength.

"H- Huh? Alex, wha- Ahhhh!"

You threw her on the bed, making sure not to hurt her in the process, and mounted her rump from behind. Her face was stuffed into the bedsheets in the same fashion as the wall, but her hind legs hung off the bed and shakily stood up on the carpet. Her other two hooves quickly grabbed the sheets in preparation for an upcoming fucking.

You could tell by the look on her face that she loved it when you were forceful.

Your jet black horse dick swung back and forth between your legs as you lined up the tip between her ass cheeks yet again. You were almost tempted to stick it in her ass because of your intense pleasure trip, but you wanted even more to cum inside your marefriend.

"Baby... Ahhhh...." Vinyl let out a moan into the bedsheets as your cock pushed against her opening. "Please, I want you to cum inside... Give me your jizz..."

And at that point, you completely lost it. You hips slammed right in between her perfect white ass and into her soaking wet fleshy marehood. As you pulled out and pushed back in, sloshing noises confirmed that she was just as turned on as you were. Vinyl bit into the bed sheets and kept giving muffled moans and screams as her body rocked back and forth on the bed due to your forceful thrusting. You couldn't think straight and all you could focus on was your hips pushing into your marefriend over and over again. It was as if everything else around you faded away and all you could see was her perfect body as you made passionate love to it.

You couldn't take much more. The all-too-familiar pumping sensation started in your lower stomach yet again.

"I... I can't... I'm cumming! Fuck!"

What happened next couldn't be accurately described in words. In short, you felt as if your cock was melting inside of her. The pumping of your thick potent semen and her inner walls throbbing around you gave you a sensation that made you yell out in intense pleasure. Your balls squished against her crotch as you froze with your entire length inside. You came hard, giving her several ounces of your cum.

Apparently, the intense feeling of cumming inside was mutually appreciated because Vinyl's orgasm hit shortly afterwards. Even though your cock was sitting still inside her, the pumping and the hot jizz pouring inside of her was too much for her to handle. Instead of screaming, she went silent and her eyes rolled back in her head slightly.

"Holy Celestia... Ahhhhnnn..." Vinyl finally let go of the sheets in her mouth and looked back at you.

You didn't stop there. There was no way such a horny cock would be satisfied after just two orgasms. Whilst keeping yourself inside her, you laid down on the bed on your side with her back facing you. You lifted one of her legs up and, with one hoof, turned her head around to kiss her deeply as you resumed pounding away into her. Quickly, you felt her warm slippery tongue swirl around yours.

"Mmmphhhh!!!" Vinyl nearly screamed in your mouth.

Because of the speed of your thrusts, your balls slapped up and tapped her clit with every complete entrance inside her. You could feel it despite the intense feeling in other areas and you were sure that it was doing something to get Vinyl off as well.

Suddenly, with as much force as you exerted earlier, she lifted her hips and pulled herself off of your joy stick. After just a few moments of rough housing and intense making out, she pushed you on your back and crawled on top.

Vinyl had to catch her breath before speaking.

"Hah... My turn..."

You looked down to see her stroking your cock that was dripping wet with cum and mare fluids. As she raised her hips to put you inside of her yet again, you saw a thin white trail going down her and leading from her entrance from where you came inside.

Expecting her to take her time, you grabbed onto her hips and pulled her down on top of you. However, she wasn't planning on doing so and the two combining forces made her take your entire length in all at once. She yelled out so loud that you were afraid the neighbors would hear.

Vinyl put the rest of her weight onto her front hooves which planted themselves on your chest as her hips began to rise and fall. There was no way your lustful sex drive wouldn't allow you to bounce your hips up and down in sync with her riding. Your hooves slid around to her ass and you squeezed it while your girthy veiny black horse cock continued to plow into Vinyl's tight hole.

Her front hooves began to tremble and her body soon collapsed on top of your chest. Her head tucked under your chin and she continued to moan against your fur as you kept thrusting up into her.

"Mmmph... So much for your turn..." You grinned mischievously and tilted her chin up to look into her eyes as you fucked her.

"Ah... Ahhhhnnn..."

Her eyes were completely glazed over and she could only respond in moans, hinting that her dominant strength was gone and she was completely at your mercy.

You tilted your head down and kissed her passionately. She opened her mouth wide so you could explore her mouth with your tongue as you explored her marehood with your cock.

You started to moan a bit more and you felt your third orgasm approaching. Vinyl must've sensed it because she broke the kiss and began licking on the nape of your neck; it was one of your weak spots.

Her legs trembled and you started to feel yourself melting inside her yet again. You closed your eyes and moaned deeply with the added plesure of having your neck licked and kissed. Vinyl didn't have the strength to cum anymore and she instead pressed her warm body against your chest, breathing in and out heavily as your cock pumped your gooey jizz inside of her.

Your eyes rolled back as Vinyl's did earlier and you realized that as soon as your sex-driven adrenaline rush ended, you would most likely pass out from exhaustion.

"Hah... One more, babe... Hah... I wanna feel your cum all over me..." Vinyls words tickled against the fur on your neck.

"Damnit, this girl's gonna milk me dry..." You thought to yourself while flipping her over to her back and mounting on top of her.

You nibbled and licked her ear in revenge for earlier and you felt her hooves wrap around your sturdy back as your cock, still as miraculously hard as ever, spread her marehood wide open one last time. She wasn't as tight as before because you had been bucking her silly, but the warmth and wetness of her marehood gave you enough pleasure to push forward towards a last climax.

Her hooves pulled your body down on top of her so that the two of your bodies were pressed together and you immediately began to make out with her once your lips were close to hers. Her fatigued moans resonated inside your mouth every time your thrusts made her bounce up and down.

Vinyl didn't make any recognizable change in her whorish moaning, but you could tell that she came again because your cock felt her walls squeeze your stallion stick tight. Before, you were somewhat worried that it might've taken an hour for your next orgasm to come, but the sudden tightness of her marehood increased your pleasure levels exponentially.

Her front legs curled around your neck while her hind legs pulled your hips closer to her. All of a sudden, she broke the kiss and screamed out with her mouth right next to your ear. Her orgasmic yell went silent and she left her mouth agape while she slowly came down from her cumming. Her eyes rolled back into her head even more than before and you were afraid that she would pass out, but her surprisingly powerful legs were still embracing you and keeping you from continuing your thrusts.

The only thing you could do was grind inside of her since you were virtually locked in place. Vinyl had zero energy left, so she responded with silence as her tongue hung out.

One throb of her inner walls triggered your final orgasm. Remembering where she wanted it, you slid yourself out of her with her legs no longer holding you back, and started to stroke your long thick horse cock above her sexually exhausted body.

It wasn't nearly as good as the first since most of your cum had already been dumped inside of her warm marehood, but seeing spurts of your seed splatter all over her body, face, and mane made it a worthy finish. You managed to miss the inside of her mouth even though it was still open and panting heavily. She still circled her tongue around her lips to lick up any nearby semen she could reach.

After watching her swallow, your body collapsed onto the bed next to her and you started to pant with her. Your stiff dick pressed between your belly and the sheets and you felt it pump one or two last tiny spurts of cum before going back to throbbing.

One of Vinyls' stockings rubbed against your leg and you felt how damp it was due to her fluids. You soon felt her weight on top of you as she rolled over. Her belly rested against your back and all of your sticky cum was sandwiched in between.

"Merry Christmas, babe..." Vinyl whispered into your ear which was soon followed by her nibbling at it and panting.

Meanwhile, your face was contorted into a satisfied grin which was accompanied by rosy cheeks as you thought to yourself.

"Best. Christmas. Ever."

"Come on, Spike! If we don't do something, it could get even worse than it already is!" Twilight exclaimed as she picked up her assistant and put him on her back.

"Wait! What if they're-"

"What if they're what?"

"What if they're... You know..." Spike grew nervous about the concept of barging in on a love-making couple as the two of them dashed out the door. Twilight quickly shut and locked the door behind them once her tail had made it out.

She groaned. "That's not important! Vinyls life could be in danger!"

"Still, could we at least knock first? I don't want that image burned into my head forever..."

"Whatever, Spike. Did you mail that letter to Princess Celestia yet?"

"Huh? You mean you were serious about that?" Spike, as clueless as ever, raised an eye brow in surprise.

"Yes! This kind of illness hasn't been recorded or documented in centuries! It's imperative that she know about this!" Twilight seemed to be on her last nerve with Spike, but he reluctantly summoned parchment and one of his new ink pens.

Using Twilight's back as a pseudo-desk, he quickly wrote:

"Princess Celestia,

Your presence is required in Ponyville at once. No time to explain. Rare illness. Vinyl Scratch and possibly Alex in danger. Meet at hospital.

Twilight Sparkle."

and then sent it off in a green puff of smoke.
