Things that go "Unf" in the Night
You could handle the complete lack of responsibility since being flung into this world naked as the day you were born.
You could handle the vegetarian diet, despite some serious cravings you were having for cooked meat. Fuck. You really miss being able to order a steak.
But what you couldn't handle was how ponies just didn't find you attractive, being the hairless ape that you are. They'd come around someday, but patience was never something you were good at, and right now, you really had a hankering for some magical pony poontang.
Earlier on that day, you sat on the sidelines in Ponyville while Twilight and her friends metaphorically tore a travelling magician pony a new asshole, for reasons that weren't entirely clear. Either way, she'd been run out of town, and as the sun started setting, you noticed smoke in the distance against the orange glow of twilight, and that gave you an idea. You start to walk towards the smoke, your nose really starting to pick up the inviting smell of a small, hastily-assembled campfire. You curse your senses as it reminds you of steak again. As the campfire comes into view, you catch sight of that magician pony from earlier. Ponyville is some distance away now; almost no chance of somepony coming to her rescue should things get loud.
Your dick twitches, sensing an end to your involuntary dry spell; this time, you weren't going to take no for an answer.
You approach the pony at the campfire, momentarily startling her. She appears to recognise you. "Aren’t you that hairless monkey from Ponyville?" she asks.
By God, you were starting to get really sick of that description. "Yeah. I came by to say hello, I saw what happened earlier."
"If you mean what those neigh-sayers did..." the unicorn signs, and stokes the fire with a twig in her hooves. "Trixie is used to it. Did you come here to rub it in my face?"
"No, I actually came here to talk," you say, lying like a professional.
The fire was dimming, and even you could tell that it wouldn't last more than an hour at most. "If you wish to join Trixie by her campfire... Trixie would welcome it; I just need to get some more firewood."
Trixie gets up, still wearing her cape, and goes into her wagon. Like a divining rod, your dick twitches once again in her direction; you obey like the degenerate fuck that you are and approach the doorway at the rear of the wagon. You can see that Trixie is trying to reach something on a shelf; almost as quickly, she notices your shadow, causing her to turn around slowly. For the first time, you see fear in her eyes, its menacing claws beginning to wrap around the unicorn's most basic instincts. The bit drops for Trixie.
"You-You're not really here to t-talk, are you?" she stammers, walking backwards until her rump is stopped by the end of the wagon, startling her.
You decide to act quickly, but unfortunately for you, Trixie decides to act quicker, her magic a good deal faster than your muscles as she smacks you square in the jaw with a rather hefty book. Fetching the book off the floor, you swiftly retaliate, and the book makes painful contact with her horn as you slam the book hard against her head.
"Argh!" she cries, as she slumps to the ground, a hoof rubbing her head as she winces in pain. You decide to capitalize on the opportunity, and you strike her horn again harder with the book, eliciting a much louder cry from the now-sobbing unicorn. You pick her up, and she weakly kicks against you. "You... you sick freak! You'll never..."
Trixie's pathetic verbal assault is cut short by your fist landing a sharp, hard punch to her stomach, winding her and putting an end to any serious attempt at resistance, the pony's sobs now interrupted by the sounds of wheezing and snivelling.
With your prey now safely subdued, you forcefully remove her cape with a hard tug, the small jewel clasping it at her neck falling to the floor, followed by the cape itself. Wasting little time, you now remove your belt and pants, freeing your rock hard dick from its confinement. The chilly air against your hairy buttocks feels awesome, but you know that what is about to come next will feel even better; you forcefully bend Trixie over the bed, followed by an immediate and enthusiastic thrust into her, a moan escaping your mouth as you sink your entire length into her cunt. The blue unicorn can only weakly protest at the pain from her dry tunnel as you start to pump away, privately admitting to yourself that those cute grunts she makes are a real turn-on, even as she continues her ineffective protests. "Trixie will... never... let you get away... with this..." she says, as your body weight holds her down to the bed. Her spirit impresses you, and you relish the opportunity to crush it.
After barely a minute of you solidly pounding away, Trixie's vagina betrays her as her snatch clamps around your rod, while the mare's quickened breathing making it clear that she's just had an orgasm. Her refusal to even look at you confirms that she feels disgusted by it, and knowing that seriously gets you off as you fast approach your own climax. Your dick starts twitching again, and Trixie knows it, her limbs still attempting to resist your domination of her, but you know that even in her own wagon, Trixie is completely at your mercy.
Feeling yourself about to tip over the edge, you ram as much of your shaft as possible into Trixie as months of pent-up sexual frustration start to empty into your captive, as spurt after spurt of your hot, virile seed makes Trixie its home. As you go limp, you apply your full weight to the hapless pony beneath you, the sounds of ugly sobbing and heavy breathing now beginning to ring clear to you as your mind enters that post-coital state of mind that reminds you that the room now smells like sex and shame. You start to wonder if there is a smell that doesn't make you horny.
Not even willing to entertain that thought, you pull your length out from Trixie, taking the opportunity to wipe your dick on her bedsheets. Taking a seat next to the bed, you can see the defeated magician laying on the bed, her fires of protest well and truly quenched by your significant stash of spunk in her snatch. She has just enough fortitude to turn her head to you. "You... you got what you wanted. Just leave Trixie alone now," you hear her say.
You remember that you're basically in the middle of nowhere out here and that Trixie certainly won't be missed any time soon. You have only one reply to her request.
"No."
Trixie's expression goes from one of cold rage to one of sheer terror.
"W-what do you mean?" she stammers, her eyes going wider.
"I'm not done yet," you say, reaching your hand out to grab the unicorn's horn. Trixie yelps in pain as you use her horn to stuff the unicorn's head into her pillow. You've violated her once, but there was still lots more of the pony to desecrate. You're still hard, and as you line up your penis with Trixie's ponut, the unicorn's blood runs cold. "N-no, not there! Not there!" she protests, but you've long since stopped listening. Without bothering to lubricate yourself first, you spear her anus with your dick, generating a scream from the unicorn. As you bury all of your rod inside her, you take a moment to get comfy, and then start to pound the pony's plush, plump rump. Looking down, you can see smears of blood on your cock, impressed that you managed to tear Trixie's butthole when you went in dry.
Trixie is audibly wincing in agony as your dick repeatedly intrudes into her back passage, the exposed anal tear causing a considerable amount of pain and discomfort as fresh tears soak into her pillow; she didn't know that someone was capable of this kind of cruelty, and you were only too happy to oblige giving the lesson. Having been drained already during your earlier session, it takes a few minutes longer for you to approach your peak, once again hilting yourself as much as possible as you pour out another hot steaming load of spunk into her rectum. Only this time, Trixie doesn't even get the consolation of an orgasm, only a constant shooting pain from her abused hole.
You extricate yourself from Trixie quicker this time, your shaft now covered in a mix of blood and feces as you notice both of Trixie's holes are now visibly leaking a suspicious-looking white fluid; this time, you elect to clean your staff of penetration using the unicorn's discarded cape, a rather beautiful crimson skid mark now adorning the lavender fabric as you toss it back onto the floor, discarding it like you did the feelings of your reluctant partner. You look over at Trixie, her expression now one of blank shock as she holds her forehooves close to her chest, her resolve now well and truly broken. You start to wonder if a human could get a pony pregnant. That important thought is interrupted by your bladder, rudely letting you know that it's full.
You contemplate relieving yourself outside, but you discount that idea; after all, what are you, some kind of animal? The wagon has precious few alternatives, but the unicorn on the bed looks like the perfect recipient. Peeling back the foreskin on your flaccid cock, you free the last vestiges of shame you had and unleash a stream of hot, steaming urine directly on Trixie's back. Her expression doesn't change, so you get bolder, and like the master manipulator of the streams that you are, you co-ordinate your efforts to Trixie's face; she closes her eyes as a reflex, followed by her nose crinkling as she instinctively stops herself from breathing, the only thought running through her mind is for the torment to end. After nearly a full minute of you urinating on Trixie, your stream turns to a dribble, and you shake off the excess drops onto the soaking-wet pony.
Trixie doesn't move at all, and you use the opportunity to get dressed. Still, it felt wrong to leave Trixie in her present predicament; you reach up and grab a log of firewood from one of the shelves. You drop it onto the floor of the wagon for Trixie to use for her campfire outside, "Wood for your fire. Best hop to it if you want to keep it lit."
You walk out of the wagon, and head back toward Ponyville; let it never be said that you don't ever do good deeds for people.
