On a wonderous lavender night, you, the human were spooning a small lavender unicorn known as Twilight Sparkle. A blanket covered you to keep you warm on this cold winter night while you lay in bed with her. But other than that you were completely naked. Your furry pony friend kept you warm, her body radiated soothing heat from under the blankets.
Your head was buried into her silky soft mane. Your hands rested upon her upper back. Her warm, soft and furry body felt incredible against your bare skin. Your fully erect, six-inch-long cock poked her plump backside. Your ‘female’ equine friend’s cock was much larger than yours. She must have been at least 20 inches long. Her member was about as thick as one of her back hind legs. She was a female despite the fact she had a penis.
You were nervous about this, to say the least, but you were willing to try being less of a prude. You trusted Twilight not to destroy your asshole with her monstrously large cock.
She did indeed have a vagina, just above her grapefruit-sized balls. Incidentally, your balls rested upon hers. They were small and insignificant when compared to her massive purple balls. Your cock’s tip rested on her right asscheek and touched off her cutie mark.
She had a plump, semi-donut-like asshole on top, a vagina in the middle, followed by a set of huge purple balls, and a massive cock. Her long, purple cock had black blotches along it.
Twilight’s plump backside covered much of your lap, along with her heavy ballsack. Both her vagina and balls radiated soothing waves of heat. You agreed to do this trust-building exercise with Twilight as part of a friendship lesson or something. She was one of the few mares that did not flex her penis at you. Penis flexing apparently was away to get a stallion’s attention. However, this made you terrified and caused you to run away as fast as your legs could carry you.
You were thankful that rape was illegal here and was considered an even worse crime than murder. It seemed your asshole was safe from freakishly large horse cocks going up it.
Twilight had poor social skills. This worked to her advantage. Sure you would see her get erect when she spoke to you. She was one of those ‘nice mare’ types. Apparently, this kind of mare doesn’t get the stallion here on average. Stallions love strong and assertive mares that flex their penises around with pride in public. Twilight was nowhere near aggressive with her advances compared to most ponies. She seemed to be a socially awkward nerd. She didn't flex her penis at you when you first met her, unlike most other ponies. You just did your best to try to ignore the erection she had while you engaged in ‘small talk’ with her. Or whatever she considers ‘small talk’.
Back in the here, and now, you decided to reward Twilight for her non-brash nature. You reached your hand over her and took hold of the upper section of her cock, near her bloated tip. Partially at least, she was really thick… really… really thick.
Twilight gasped at the feel of your hand touching her cock. “Anon? You like my penis?”
“I… errr… I’m trying to,” you said in a low voice.
“If you don’t like my penis, you don’t have to jerk me off. I don't want to force you to do anything you're uncomfortable with. We can just spoon tonight if you want,” she said softly.
You sighed deeply. “I want to. Even if I don’t want to.”
With that, you began to stroke her penis. It was hot and hard to the touch. Twilight moaned happily and made a series of horsey sounds as you tenderly rubbed her penis. The sounds she was making were music to your ears. For quite some time you stroked Twilight's cock, listening to her happy moans and whinnies. Twilight’s marehood soaked your lap, it leaked thick and creamy fluid onto you.
You took hold of your cock with your left hand. And you guided it to the entrance of her marehood. Teasingly, you rubbed the tip of your cock against her wet, quivering marehood. Your cock quickly became lubricated with her leaking liquid. You took a deep breath and pushed your cock into her. Twilight for her part uttered a loud whinny as you pushed your way inside her. Her marehood clamped down hard on your cock, making the journey long and arduous.
Your balls came to smack against her lovely backside when you bottomed out inside her. You didn’t move, you took this moment to appreciate the soothing feel of her strong vaginal muscles hugging your cock as it lay lodged inside her. Twilight tilted her head to the side to face you, followed by bringing her lips to yours with a wet smooching sound. Her large equine tongue came to enter your mouth.
You and Twilight moaned in bliss as both of you exchanged tender intimacy. Her tongue swirled about in your mouth, exploring it. You licked the underside of her thick, equine tongue in your mouth. This kiss prompted you to slowly pull your cock back from within her squeezing marehood (the sheer tightness of her marehood made it difficult to quickly pull back) to near the point of exiting her before you came thrusting back inside her with your balls smacking against her lovely backside. Twilight uttered a muffled whinny in your mouth. You grunted from the tight squeeze of her marehood clamping down hard on your cock when you bottomed out inside her.
You held your cock in place, you felt as if you were about to unleash already. Twilight's warm and soft marehood lovingly squeezed on your cock, trying to coax you into releasing inside her. The mare whined sadly when you pulled your mouth away from her muzzle, a strand of your saliva fell from both of your departing lips.
“Twilight…. I-I… I won’t last long. I hope, I won’t disappoint you. I know I'm not as strong as a stallion. I’m just a human after all,” you said in a low voice, ripe with worry.
Twilight leaned forward and kissed your cheek with a wet smooching sound, and spoke softly.“Oh, of course not. I had a feeling that your cock had nowhere near the endurance of a mare. Or even a stallion for that matter. The average stallion’s cock is about 12 inches. Whereas a mare’s is usually about 20 inches long. Yours is merely 6 inches long.”
You sighed deeply. “Uhhh, Twilight, that’s not exactly making me feel better.”
“Oh… would it make you feel better to know that a mare’s vagina can squeeze down very hard? You don't feel that much different compared to a mare to me”
“So, you're not a virgin?” you asked, raising your right eyebrow.
Twilight fidgeted with her two front hooves nervously. “Well not exactly. My female friends have had sex with me, but I never had a stallion, until I met you. Again, you don’t feel much different when compared to even Applejack, and she’s 30 inches long.”
With Twilight’s reassuring words, you brought your mouth to hers and resumed kissing her. Twilight for her part squealed happily as you rejoined lips with her. Subsequently, you returned to thrusting your cock back and forth against her lovely backside.
‘Plat, plat, plat’ came your balls hitting her plump rump. You endured Twilight’s squeezing marehood down on your cock each time you bottomed out inside her. Twilight for her part uttered muffled whinnies and moans in your mouth. The mare found herself jerking her hips back and forth against you, meeting your cock in time with your thrusts against her backside. Her massive cock bobbed up and down, repeatedly smacking against her torso as it jerked back and forth during her movements.
Your breath became shallow and you found yourself near the point of release. This time you did not hold back. You thrust against Twilight’s lovely rump one last time and drove your cock as far as it could go inside her, this was followed by you unleashing a deluge of your creamy human spunk inside her as you moaned into her mane. Twilight uttered a deep throaty moan in your mouth, her marehood subsequently soaked your cock and your lap below. At the same time, her cock swelled even larger by a good few inches before it unleashed a volcano eruption of her thick and creamy marecum.
You only lasted a few seconds with a few spurts of cum inside her. Twilight on the other hand was like that of a fireman's hose as her cock blasted bucket fulls of marecum out of her ejaculating cock. You looked on in awe as Twilight unleashed a continuous wave of thick and creamy marecum. You were not safe from behind her. Your lap was soaked with a monsoon of her marecum spurting out of her vagina.
Twilight’s cutie marks began to glow with blinding light, and the mare subsequently began to grow larger. You found yourself being pushed back as her air ballooning rump swelled in size before you. Your softening cock immediately slipped out of her marehood, and came to rest against her asscheek. You don't know what happened but within the space of a few seconds, your vision was now dominated by a pair of beachball-like-sized asscheeks in front of your face. You looked up to see she had a pair of feathery wings on her back. It appeared she had become an alicorn.
Your eyes drifted downward to look at her balls to see that each one was now the size of a watermelon. You found yourself becoming erect again, and you immediately brought your cock between her asscheeks. However, there was quite a bit of a problem. The canyon gap between her asscheeks to her marehood was quite substantial. You were quite inadequate for the much larger mare now. Nonetheless, Twilight squeezed her asscheeks together and welcomed your cock between them. Your cock was wrapped in their soothing, heavy softness creating a makeshift vagina for you.
You brought your hands down upon her massive rear and took a tight grip. Your hands sank deeply into her plush softness, your hands dug in like memory foam into her huge squishy soft ass. Even now Twilight did not seem to care that you were even more inadequate for her. You began thrusting your cock between her asscheeks.
Twilight moaned happily as you thrust your cock back and forth between her lovely asscheeks. Her massive, bubbly cheeks jiggled about like a stormy ocean as you thrust against her, not only that but her balls smacked against one another as she jerked her hips back and forth. In addition, you could hear her buttcheeks clapping together as they smacked against one another with loud meaty slapping sounds of flesh slapping against flesh.
You found yourself succumbing quickly to Twilight’s wonderful ass. You grunted, as you subsequently unleashed between her asscheeks and delivered a small spurt of cum into the canyon of her buttcheeks. The mare sighed happily at the feeling of your cum hitting her cheeks.
You heard the hum of a horn and Twilight subsequently shrunk back down to normal size. Your vision was no longer dominated by her beach-ball-sized asscheeks. Your head was returned to resting on her mane. Your hands were still upon her buttcheeks and still dug quite deeply into the plush softness of her ass.
“Heh, I got a bit too big back there. Even with pocket dimension magic, I believe my cock would struggle to fit inside you,” she said in a cheeky tone.
You gulped. “Be gentle Twilight. Even at 20 inches long, your cock could destroy my asshole,” you said nervously.
“Of course. I love you, Anon,” she said softly.
“I love you too,” you said, partially taking hold of her super thick, and long cock with your right hand, causing her to moan softly.
