Horse Riding

Nestled deep within a huge ass oak tree there was a cute, little purple unicorn. She asked you so… so many questions. However, you were very eager to answer them since she promised you a meaty steak as part of a ‘friendship lesson’ or something like that. Whatever the case may be, you were getting steak. You were getting pretty sick of eating vegetarian food. You wore a fancy black tuxedo for this interview.

You, the human were sitting upon a wooden stool. Across from you, on the other side of a circular wooden table was said unicorn, who was known as Twilight Sparkle. Her horn was glowing deep pink as she held a book in her magical grasp. While at the same time, floating above her book, she held a black-feathered quill pen at the ready.

“So, you mentioned earlier that you have ponies in your world. But they are far more ugly and stupid when compared to us.”

“Yeah, what about it?” you asked.

“How do humans interact with these ponies?”

“Well, Twilight. It depends on what country the ponies are in. Ponies are seen as animals for children’s entertainment in the form of horse riding where I am from.”

“Horse riding? I know what a horse is, that’s a slur to insult ponies. But I don’t get the riding part.”

“Before I answer. Can I ask why the word ‘horse’ is a slur?”

“Well, it means you are ugly basically to call somepony a horse.” her ears folded backward, as a look of worry crossed her face. “You don’t think of me like a horse, right?”

You reached your right hand out to her and began to tenderly scratch the back of her ear. Twilight in response moaned softly, and her tongue lolled out of her mouth. “Th… that… feels nice.” she shook her head, before she flashed her horn, and gently pushed your hand away. “That was nice but distracting. Let’s get back on track. You were going to tell me what horse riding was.”

“Horse riding is when a human rides around a horse’s back. Horses have been used by humans as the fastest form of transportation on land for thousands of years. It only became surpassed with the invention of the car.”

“Ah, I see. I’ll question further on what a car is later,” Twilight stood up, and turned around to show you her backside. Your eyes widen at the sight. Despite her being significantly shorter than you, this cute little horsey was packing a very shapely, plump bubblebutt. Her tail obscured her assets. “But right now, I want to see if we could try out some horse riding.”

You made to stand up, and moved to stand behind her. Her plump ass perfectly met your hips at the same level. It was just the right height to ‘ride her’ in another way. You found yourself increasingly attracted to these ponies. While they had small tits between their back hind legs, they more than made up for it with their plump asses that put any human woman to shame.

Twilight looked back at you, with a big cheesy smile upon her face. She eagerly awaited you to mount her. With all that considered, you suddenly found yourself nervous about this. Twilight seemed to pick up on your hesitation.

“Are you okay, Anon?” she asked softly.

“Yeah, give me a sec,” you took a deep breath, before you stepped forward over the small unicorn, and then you gently made to sit down upon her back. Your feet made contact with the wooden floor underneath, Twilight was a bit too short to ride. On a side note, the softness of her velvety fur was wonderful. For some reason or another Twilight moaned in bliss the moment you sat down upon her back.

Twilight giggled with a hoof over her mouth. “You seem too tall. I won’t be able to have you ride around on my back without your shoes scraping the floor,” her eyes shrunk to pinpricks when she felt something long and hard poke her back. “Did you just get an erection?!” she bellowed in alarm.

Your face went red like a tomato in embarrassment like a true gammon. You proceeded forth to stand up in order to stop your massive cock from poking her back. You turned around to hide your shame protruding inside your pants. “I’m sorry, Twilight. I didn’t mean to get an erection. I’ll just go now,” you said in a low voice.

You made to walk away, but you stopped when you felt a soft hoof take hold of your right hand. You turned around to face Twilight, who was smiling at you as she held your hand with her hoof. Her hoof was flexible as it lay curled around your own appendage

“Would you like a steak, beer, and a blowjob? And then we can mate for science, and then I could write a letter to Princess Celestia for a friendship lesson report.”

“I would be delighted, Twilight. But could I ride around your back for a little longer?”

“Sure, hop on.”

You stepped forward and sat yourself down upon her back. You then leaned forward, and rested your head upon her soft mane. Your cock felt tight in your pants as it poked her back through your pants. Forthwith you began to kiss her neck, earning yourself a happy whinny from her.

You reached your right hand back to her rump, and delivered a hard slap upon her cheek. Twilight’s body shivered as she moaned loudly, bucking her legs instinctively. “Oh Celestia… what did you do?!” she asked, panting hard.

“Uhhh… slapped your butt?” you asked, blushing. You suddenly could smell a distinct aroma, like lilacs and lavender. ‘Did she just- ?’ came your thoughts, before being cut off.

“That can’t be it, I’ve been hit there before… no, it had to be… MY CUTIE MARK!!” she realized, looking at where her luscious rump still stung. Silence pervaded between the two of you as this realization sank in. The unicorn then simply smirked.

Twilight lit up her horn with magic, and locked the front door. You yelped when your clothes vanished out of thin air, leaving you naked atop the mare. Your massive cock was now free from the tight confines of your pants. It was well above 10 inches, far surpassing any pornstar you've ever seen. It must have been at least twenty inches long, if not more so.

You shuddered at the softness of her fur against your bare skin. Twilight stared back at your massive cock resting upon her back. “Like what you see?” she joked as she looked over your meaty rod intensively.

“Yeah, you’re a real sexy little horsey.”

She giggled. “Can we skip the foreplay? I want you to mount me raw.”

You made to stand up, and positioned yourself behind Twilight. Her tail was wagging from side to side in excitement. Her soaking marehood was winking at your cock in greeting.

Twilight made to walk backward, and pushed you up against a wall. Your huge cock came to hotdog the cheeks of her ass. You brought your hands down, and lay them upon her cutie marks. Your hands sank into the plush softness of her rear, before they made contact with the strong muscles underneath.

Twilight took a few steps forward, to allow your long cock room to mount her. Your massive cock was now perfectly aligned with her marehood. Twilight stared back at you with a pleading doggy eye look, begging for you to mount her.

This told you all you needed to know, so with one fell swoop you pushed forward, and slammed your cock into her. The mare cried out as your huge cock came pounding into her pussy. You grunted as you clenched your jaw from the sheer tightness of her pussy. Slowly, you pushed forward as inch, after inch of your long cock gradually made its way inside her.

Moans, groans, and horsey sounds left the mare before you, as you slowly drove your cock into her. Eventually, your cock slammed home all the way into her pussy. Your balls came to slap against her buttcheeks with a loud meaty slapping sound of flesh slapping against flesh.

Her lovely, soft rump felt wonderful against your body. A strong wave of heat emitted off her marehood. Her pussy clenched hard around your massive invader, trying to milk you for your seed.

Twilight leaned her head back towards you as if she was trying to kiss you. You leaned down over the mare and brought your lips to hers. The two of you moaned in bliss as you kissed. You lightly thrust your hips against her as you kissed, pulling back only by an inch or two.

Twilight uttered a muffled cry of pure bliss during your kiss from the feel of your massive cock pistoning against her backside. You felt a tingling feeling in your cock, you were close to release already. The mare whined sadly when you abruptly stopped kissing her. You pulled back to near the point of exiting her, and then you came slamming back home deep inside her, before unleashing inside her with a loud moan.

Your hands resting on her cutie marks glowed with blinding light for a brief moment, before her cutie marks in turn did the same. A blinding light, accompanied by your pony lover howling in orgasm, overtook your vision as you felt Twilight’s butt seemingly… ‘inflate’.

“Huh?” you asked aloud as you feel your body being pushed up, or maybe pulled up, as Twilight’s height increased. When the light dissipated, you were now hugging onto the huge ass of a tall alicorn.

“What… what just happened?” asked a confused Twilight Sparkle as she almost got vertigo from the sudden change in perspective. She almost fell over, unused to the weight shifts and longer legs. The only thing keeping her from taking a tumble, was you still latched onto her backside.

The wings also kind of freaked the poor former-unicorn out. “How… how did this happen?!” she squeaked, trying to cope with these new sensations.

Twilight’s massive rump dominated your vision. It was much larger than even Princess Celestia’s rump. It was almost beach-ball like in appearance. Twilight herself was tall and imposing. She towered in the air, standing possibly at least 7 feet tall. Your hands sank deeply into the extra thickness of her rump’s soft cheeks. Your softening cock below came to slip out of her marehood.

“Well, at least I can ride on your back properly now,” you said, giving her buttcheeks a tender rubbing with both of your hands.

Twilight giggled. “You want to get on my back again and ride me?”

As if in answer, your cock rose back to attention, standing tall and proud once again.

“Dearest Princess Celestia, Today I learned that having a human riding around your back feels great. It felt even better when he rode me from behind with his massive cock. Background magic seems to be affecting his reproductive organ. Must investigate more thoroughly. His cum seems to have an empowering effect on me. I’ve become an alicorn, and gotten quite big. I think I’m even bigger than you, Celestia.”

“Your faithful student, Twilight Sparkle.”

Celestia giggled as she rolled the scroll back up. “Good to know that I’m not the only one who’s realized this fact. Can’t wait to see what… comes of this study.” she said as she sipped her tea.

Celestia found herself suddenly sad, as a tear went down her cheek. Her human love, Commander John Shepard from a thousand years ago was no longer with her. His soul was bound to the dream world. Only at night in her dreams could she see her love with the help of Princess Luna. Her human love too was the one who made her an alicorn.

Celestia frowned at the prospect of being surpassed in size. If Twilight is telling the truth, she now has the biggest rump in all of Equestria. She made a mental note to feed on this love from the human herself so she can have the bigger rump once more.

“Just you wait, Twilight. I will have the bigger rump. Nopony has a bigger rump than Princess Celestia. I have the best rump on the Citadel,” she said in a low, bitter voice.
