It's weird waking up with someone in your bed, when you've been used to sleeping alone for years. It's even weirder when it's with not just one, but two beauties. But the thing that completes the weirdness is the fact you woke up with Octavia's plump ass right against your crotch. Not something you ever expected to feel one day.

Your body naturally turned towards her during your sleep, you have an arm right around her waist that you almost pull back instantly when you notice. But that would wake her up.

Vinyl's face is pressed against your back. Okay, maybe she's the one that made you turn during your sleep.

They're both asleep. Judging by what little light passes through the shutters, you guess it's still the middle of the night. You feel a bit tired, but not that much. Way less than the times when you fapped on your own before bed. Could it be because of the infusion Tavi got you?

As you ask yourself that question, you look at the dimly lighted body in your arms. Octavia's gray coat, her long dark mane so close to your face you can smell her shampoo, the soft contact between your skins. All under the barely visible neon light filling the room.

But, of course, your attention inevitably goes to her breasts. That massive bosom, right next to your arm. Their fat nipples. She did say you can do whatever you want, right? Even if she's sleeping?

Time to put that to the test. Gently, you move your hand until it reaches her breasts. You knead it, slowly, appreciating its shape, its bounciness, the weight, how much it squeezes under your fingers. Kinda like a stress-ball, but way better.

Her breath gets a little heavy for a second, as you play around with that wondrous curve. Just toying a bit with the nipple is enough to get your stallionhood up for some fun again. Looks like the infusion got its effect right. You slowly rub yourself against Octavia's ass and back. The fact you can do that is still out of this world to you.

She breathes in suddenly, in a shiver, before opening her eyes. She immediately looks at you, with only a sleepy surprise. When your eyes meet, when she sees your desire, she smiles and gives you a gentle but brief kiss on the lips.

"Naughty colt," she whispers.

"Can't help it," you say, grabbing her breast more firmly.

She bites her lips, pushing her ass against the base of your shaft, rubbing against it slowly. Sounds like she's up for it.

You roll with her, on top, still rubbing against her back. She giggles a bit.

"Don't wake Vinyl. She won't let you sleep until morning otherwise."

"Is that a threat or a promise?" you playfully reply, standing up on your knees, a quick gesture of your hand inviting her to raise that flank.

Which she does, presenting her ass to you, lifting her tail so you may get the best view possible. You help yourself, grabbing her two round cheeks and spreading them apart, getting a nice look into what the lusty mare has to offer. Two dark and sweet lips and a small but quite noticeable backdoor.

Your eyes stay locked on the latter one. You consider it. You only got one night, you can do whatever you want. And with her, nonetheless.

Would that be too much to ask? You look at her, then notice on the nightstand, right next to her glasses: lubricant. She planned for it.

"Enjoying the view?" she asks, seeing you take your time.

You certainly are. But you also nod your head towards the lubricant. She looks at it, smiles and grabs it, handing it to you. Once you take it, she grabs her pillow and crosses her arms around it, holding it against her muzzle, ready to muffle her soon to come noises.

Better prepare her well. You open the bottle and take a generous amount of lubricant on two of your fingers. With care, you apply it on her precious place. As soon as the liquid touches her, she shivers. Probably because it feels a bit cold. Drawing small circles with your fingers, you gently push some of it inside. Her ass-cheeks contract, her hole winking against your index and middle finger, as you hear her breath out against her pillow.

Slowly, you push inside, spreading the lubricant onto Tavi's inner walls. She tenses up a bit, but lets you do your work, trying her best to keep her tail on the side and her small tail trail lifted. You rub your fingers inside, in and out, gently, making sure you reach as deep as you can to prepare the way. Even if, well, you barely reach a quarter as far as your cock could do.

Once you feel her entrance is ready enough, you remove your fingers, getting a little spasm out of her legs. You take the bottle again and put it upside-down above your cock, before pressing on it like you're spreading sauce on a hot-dog. Once that's done, you grab yourself, stroking your shaft with both hands, making sure every last square inch of meat is lubricated.

Octavia is watching you do it. Her eyes are locked on your cock, with heat and soft desires. She swallows her saliva in anticipation. She knows you plan on going in balls deep. And she's imagining what it'll do to her.

You rest your penis in between her buttocks, grabbing them again, rubbing yourself with them. Your veins touch her entrance, and she tightens a bit each time.

"Should I be more gentle with this place?" you whispered, remembering how she asked you to mess her up earlier that night.

She nods shyly, getting her mouth of the pillow to answer:

"A-At least at the start. I-I'm not used to that kind of caliber here."

She's way less assured than before. Not afraid or anything, but still more sensitive. Well, better not mishandle her then. You wouldn't want to hurt that oh so desirable mare.

Moving your hips back, you rest the flare against her husband hole. It twitches a bit, almost as a welcome. You gently press against it and Octavia immediately buries her muzzle back into her pillow.

Firmly holding her wide hips in place, you take a deep breath and push in. The lubricant helps a bit, making your movement a bit smoother, but still. You have to put quite some strength in it just for her ass to start spreading around your tip.

She shivers, her nails sink into the pillow, she does her best to be relaxed as you slowly push your arm-thick rod down her hole. The head finally goes in, and a couple of centimeters get shoved in right away, as you get caught by the sudden easiness of penetration. It's tight, it's warm, a nice ring is circling your rod. You hear her breath out against the pillow.

A little back and forth gets a quiet moan out of her. Which only invites you to do it again, while shoving a bit more of yourself pass the widening entrance. You feel her muscle rubbing against your throbbing vein, as she takes another deep breath in. She can't stop shivering while you make your way inside her.

Little back and forths become long and passionate thrusts into Octavia's hot insides. Words can't really do justice to how tight yet easy to slide in her ass is. Your median ring quickly passes, followed by the thickest part of your rod. Octavia breathes in a little squeal, eyes widening, but she's not stopping you at all. The rest of your shaft is quickly swallowed down to the base, as your crotch meets with the gray mare's plumpy ass. All this punctuated by a muffled moan.

You're stretching her, there's no denying it. And in a way she probably never felt before. You can feel your flare poking through her upper belly and in between her breasts. Through it, you sense her heartbeat, heavy, quick, and impatient of what's to come.

You lean on her, grabbing her breasts in a gentle yet assertive way, giving her another stimulus she wasn't ready for, as she spasms briefly when you do it.

Feeling a bit cocky, you playfully whisper into her ear:

"Hold tightly onto that pillow."

She doesn't get the time to look back at you. You hammer your sentence with a quick and deep thrust, sending her neck to tense up, while she refrains a new muffled moan. And before she can recover from it, you do it again. And again. And so begins the dance of your crotch against her round rump, moving back a few centimeters each time, only to plunge them back right away.

Being on top like that, having her breasts in your hands, her body exposed, her hole at your mercy, hearing the noises she's desperately trying to cover with her pillow. It does something to you. It fills you with something primal. You don't want to be too rough, but you want to be rough. Just the sound of her ass bouncing against your hips, it makes you wonder how much they would clap if you were going at it seriously.

For now, you contain yourself to a simple, nice, fast-paced pounding. And it's already great in its own way. Her insides grabs you, draws you in, wraps around you, almost begging for your cock to come back every time you pull out, even slightly. The bulge rubbing against your fingers is a nice bonus, and so are the long moans of your partner, always cut short by another thrust.

You knead her breasts, enjoying the pleasure you're getting from fucking that hot mare in the butt. It's so vulgar, but it feels so great. From virgin to doing the sexiest mare around, in the ass, in the span of a single night. What a dream.

You're resting your head on her shoulder, you don't miss any bit of her reactions. Her pupils retracting when you pound-in, going back to their regular size when you pull out. Like a heartbeat, but one you're dictating the pace of. The way she tries to catch her breath, but can't really do that against her pillow, so she always quickly pulls the top of her muzzle out to breath in, before burying it back again. Just by her spasms, you can tell she's enjoying every last bit of what you're doing.

Your breath also becomes quick. You're feeling burning hot. Horny like you never were. Horny for more. You don't want to just fuck her nicely. If that's going to be your only night with her, your only chance, you want to go wild. To leave an impact she won't forget, be it mentally or physically. If that ass is to be yours for one time only, better wreck it properly. So that every time she inserts something in it, she'll only be able to remember you.

Picking up a bit of pace, you start to add some strength to your hips as well. Octavia goes one note higher as soon as you do that, her muscles trapping you in a bit more. Or, at least, they're trying. But she's too overwhelmed to really contain you, even unwillingly. Her body's attempt at slowing you down, just so that it doesn't immediately drown in pleasure, is transformed into a mere better way to jerk you off.

But that's not enough. You lack reach in this position. Letting go of her breasts, you straighten up, still slamming your crotch against her behind. As you let your inhibition fall, your hand comes slapping against her asscheek, giving her an audible spank. Good thing she has the pillow, because that cry she just had would have definitely woken up Vinyl.

She turns her head, looking at you, not with reproaches, but with submissiveness. She knows you're not going to go easy on her anymore. And she's all for it. She's letting you lead. For a brief moment, you contemplate calling her a slut, but that would be a bit too far. Probably.

So, instead, you dig your fingers into those generous asscheeks, pulling on them heavily while you slam yourself into her. She tenses up again. You let go of any restrain you had and begin to ram her tender hole with your honestly oversized dick.

You moan with her. Quietly, even though the sound of your hips hitting her ass would be more than enough to cover it up. You pound Octavia like crazy. Going in balls deep every time. Adding a nicely timed spank here and there, when you feel like she's not getting enough roughness. Her eyes are slowly going backward.

During the long minutes you spend reshaping her asshole, you notice something wet running along your balls and thighs. You don't need to check, it's pretty evident just by her look. She's cumming hard. Probably harder than when you did it earlier. Could she be a true anal-slut? Or is she just sensitive for some other reason? It doesn't matter, she's yelling against her pillow all the same.

You still haven't fully recovered from before as well, it seems. While you wish this instant would last longer, ultimately, you're only a stallion. Arching back a bit, hammering her hips against you harder and harder, you let your pleasure rise progressively, before climaxing abundantly in Octavia's husband hole.

Cum flows out of you at an unprecedented pace, draining both your balls and your energy, as you pump everything into her. You still go for a couple of well meant thrusts, but your strength is gone. It already takes you a considerable effort to not just simply fall on her. You're panting, heavily, slowly. Feeling better than you ever felt.

Octavia is shaken with spasms. She's still holding onto that pillow, trying her best to calm herself down, with poor results. Her eyes are still wandering off, while her mind is recovering. Finally, she slowly turns to you, panting.

If you weren't high on dopamine, you could swear you're seeing love in her eyes. But you're not really sure of what she's truly thinking. So, you reply to that with a calmer but still dry spank on her ass. Just to feel it jiggle against your palm once more and see her giggled moan.

"Someone gained confidence," she whispers.

"Someone couldn't resist that ass," you replied, before giggling at your own dumb response. You're just feeling happy and still uninhibited.

"Glad you enjoyed it. Don't think I'll be walking straight tomorrow."

She giggles, while you're just finding that hot, weirdly enough. Looking down at her ass, you gently pull out your cock. At least it's easier now that it is a bit flaccid. That doesn't prevent her from shivering.

As you pull out, you notice she's a bit.. loose, to say the least. Her once small hole is now slightly gaping. Not obscenely, like she had just made a mold of your shaft. But you could probably slip a finger or two in it without stretching anything. Not that you're going to anyway. Now that you had your fun, your body is feeling tired again.

It seems Octavia is feeling sleepy too. She lowers her hips to lay down on the bed completely, while you lean on top of her, embracing her, giving her a gentle kiss on the cheek.

"Looks like we didn't wake up Vinyl," you say. "I don't know how."

"She's a really heavy sleeper," Octavia giggles, looking at you with tenderness. "Being used to loud noise probably doesn't help."

You smile with her, before yawning. Damn, that post-nut exhaustion is kicking in fast. And it's contagious, Octavia yawns too.

"You don't mind if I stay like this?" you ask, thinking you might be a bit heavy for her.

"I don't. Keep your thing on me, though. Vinyl is not going to be pleased if there are too many cum stains on the bed sheets."

You blush a bit, taking your shaft covered with a thin layer of your own semen, letting it rest on the mare's back. That night is going to feel a bit humid, but you don't really mind. Not like you have the strength to reach for a tissue either way.

Once done, you give her another kiss.

"Goodnight?"

"Good night," she says, resting her head on her pillow.

You lay yours on her shoulder, closing your eyes. Feeling great.

Vinyl yawns before turning towards you. Just so she can get closer to you two.

Author's Note

This one has actually been ready for a month now, but I was too busy to do the re-reading process.
Last part should arrive... I'd say "soon" but I feel like 2 weeks isn't soon at all for most people... Anyway.
