Our tale begins with you, the human, nestled safely within a huge oak tree structure. Inside it was homely and warm; a tad bit primitive to your liking, but it was by no means uncomfortable. Nonetheless, you began to appreciate the lack of technological progress this alien world has. It seemed almost mediaeval, without the filth. On the contrary, it was borderline the early industrial revolution, with the advent of trains. At any rate, technology seemed rather inconsistent here; it didn’t make much sense.
The huge tree you resided in literally had a library inside it. A great source of heat was provided by a fire, which crackled quietly in a nearby fireplace just a few feet away from you. In addition, you wore a thick black woollen jumper, accompanied by a thermal vest underneath. Down below, you wore a pair of bulky white woollen pants.
Even with the warmth of the fire, you could feel the icy cold hand of winter touching you. Outside you could hear a raging blizzard, no doubt shrouding the land in a thick blanket of snow. You were looking forward to this thing called 'Winter Wrap Up'. A certain lavender unicorn told you a lot about it. You were indeed well protected against the harsh conditions of winter.
The fireplace in front of you helped illuminate the dark room a great deal. You could see shelves carved into the surrounding walls of the tree's interior, each one filled to the brim with books. You were sat upon a soft lavender couch on the far right side of it. The couch was made of some leathery material you couldn't quite determine the source of. You believed the inhabitants around you would object to such material. Then again, this is not Earth; it's some sort of alien world dominated by creatures known as ponies, which came in a few subspecies. With all that considered, you don't know for certain. After all, there were some other intelligent creatures out there other than ponies.
Nonetheless, you safely assumed ponies would object to the use of leather since you had become good friends with a certain lavender unicorn, who just so happened to be lying down very close to you on the couch just to your left.
However, she was a tad too close to you at the moment. You didn't necessarily object to this, but it felt weird. Especially since she was your landlord, and this appeared to be a female-dominated society. The situation's awkwardness was further enhanced by the fact that she was stark naked. In addition, your eccentric unicorn friend was messing around with potions today… which resulted in her having a rather large growth spurt. You don't know if it was intentional, but it seemed to have caused her butt to balloon out quite a bit to the point her buttcheeks might as well be the equivalent of exercise balls.
Not only that, but she seemed to be extra touchy-feely today. But that wasn't really unusual since ponies are very affectionate in general. Nonetheless, she appeared to be acting stranger than usual. You did your best not to look at her bubbly rump.
A great deal of heat radiated off her plump, lavender butt as it lay firmly pressed against you. If you were to stare at her bubbly butt, it would no doubt bring you to an erection. The thick bubbly cheeks of her fat rump were perfectly round and smooth and had not even a hint of sag. So in that regard, you did your best to try not to look at her lovely butt for too long.
Occasionally you would take a glimpse at her lavender butt; she was, after all, too busy reading to notice. It was a real struggle for you not to stare at her ass. The temptation to stare at her butt was further complicated when she would occasionally flick her tail against you. Each time she did this, you assumed she was reading a particularly exciting chapter in her book.
Despite the fact you were distracted by her lavender butt, you were quite concerned for your friend. She was unusually quiet and seemed slightly anxious. Oh, she was reading alright; that wasn't unusual. You could see the tip of her horn blowing with a faint dark pink glow. On occasion, she would call you by your name. You would turn to look back at her as she stared back at you. From there, she would open her mouth for a brief moment before closing it again. The mare would then return to reading her book. Twilight seemed to be acting unusually shy.
This mare normally loves talking to you. You were somewhat lost for words yourself with Twilight's lovely rump oh-so-close. You started to believe the wild theory she must have deliberately drank that potion to trigger a growth spurt in order to have a much larger rump to get your attention. But you don't know for certain, so to be on the safe side, you decided not to question her on the matter.
Your eyes mindlessly wandered around the room as you fidgeted in place. You didn't want to stare at your landlord's fat butt being so close to you. But at the same time, you didn't want to come across as ignoring her. Frequently, you turned to look at Twilight to see if she was upset or not. Thankfully each time, the mare appeared to be happy while reading her book.
All this silliness went on for quite some time until it was eventually broken when Twilight spoke again.
“Anon?” came her soft voice, speaking your name.
Slowly you turned your head to look at her. You made sure not to stare at her lavender butt, even if it was so tempting. Her large purple eyes glowed in the dark like that of a cat as they stared into your small human eyes.
“Yes… Twilight?” came your voice, low and nervous.
“Do… do you like my butt?” she spoke with clear nervousness. You could even see a pink blush lighting up the cheeks of her face, along with her ears folding back.
To answer her question, you daringly decided to lift your left hand and place it on her left buttcheek, right upon her cutie mark. You watched in delight as your hand sank into the plush bubbly softness of her warm cheek. The softness and warmth of her furry cheek against the bare skin of your hand felt absolutely fantastic.
You took a moment to appreciate the feel of her ass before you decided to look up to see if you had made the right decision, and thankfully, you were met with a smile.
This was the beginning of a very lavender-butty romance.
