One month has passed since Twilight fully accepted Thunderlane as a friend with benefits, short FWB, and since then Twilight’s body has undergone some subtle changes.

Despite the frequent sex her body didn’t seem to calm down from its needs. Quite the opposite in fact. She felt a constant craving for some nice meat pole being shoved down her twat. Twilight theorized that her body was adjusting to the continuous stimulation as her wet canal was seemingly reshaped by Thunderlane’s dick. In the end she needed him inside her pussy at least once a day.

Or in simpler words she somehow got addicted to it.

Not that she saw it as a problem, mind you, as over the course of the last month she was simply fascinated by his dick, and also his ability to shrink it down if needed. It was a monster of a cock and Twilight simply couldn’t help but test it thoroughly with her throat, pussy, and yes, even her ass.

Aside from the arousal, Twilight also found herself getting bolder as her skirts got shorter and she found herself buying shirts and sweaters that would actually show off her belly. She felt quite a lot more sexy that way.

Especially now as she was walking down the street in a short blue skirt, with a lighter blue shirt, her hips practically swaying with each step.

Twilight of course was on the way to Thunderlane’s house, her legs slightly quaking at the mere thought of getting another dose of his healthy vitamin D. It was noon on a saturday and she knew she could find him going out of his house on a walk today. She had after all enough time to memorize his entire schedule and always kept herself informed, so that she would never miss him when she truly needed him.

And true to her calculations she saw him going directly in her direction, already leering at her form.

Twilight couldn’t help but blush as she could practically feel his gaze tearing down her clothes so that he could shove her against a wall and use her luscious body for his amusement.

As they came in each other’s reach, Thunderlane took a quick look around, before determining no one was near. He then groped her ass, making her moan out lewdly. A few wet drops of her arousal already fell from her soaked panties to the ground and her legs started to quiver even more in anticipation of what was to come.

He leaned in, his breath tickling Twilight’s ear and sending a spike of arousal through her body.

“Alley?” he asked huskily. One simple word that made the once so proud princess leak, as her clear arousal was now starting to flow down her legs.

“Alley,” she replied needily as she hurried along with Thunderlane in the nearest alley. Twilight’s horn quickly lit up, casting a newly learned illusion spell on the entrances and making sure their fun was not heard, before also casting a soundproof bubble, to also ensure they weren’t heard. Now they could do all the naughty fucking they want. She could scream out his name loudly and ponies could actually look down the alley and still she would be safe.

Not that it felt safe. It still felt risky, but that was the beauty of it all.

As soon as her horn flickered out, Thunderlane pressed her forcefully with her back against the wall, while his mouth lunged for hers. She managed a surprised gasp, before he stuffed his tongue into her muzzle, dominating her own with expertise.

The princess started to let out a barrage of delightful moans inside of his mouth, which only seemed to increase in pitch as he travelled with his hands down her blue skirt, before slipping under it, and burying two fingers inside her panties and then her bottomless and naughtily dripping wet twat.

He started to fingerfuck her, while his thumb caressed her erect clit, teasing her. Twilight couldn’t help but wink, as her hot and soaked cavern was trying to pull his fingers in.

Thunderlane chuckled as he pulled away from the kiss, while also pulling out his fingers, making the princess slut whine. He then presented said fingers to her and Twilight didn’t even hesitate as she lunged for them to greedily slurp on her own juices. Her tongue made sure every nook and cranny between his fingers was licked clean as she enjoyed the taste of her own arousal.

As soon as his hand was free, he hunched down and with one fast movement pulled her panties down with him, making Twilight quiver from the forceful undressing. She then assisted him as she stepped out of her panties, letting Thunderlane take and pocket them as he stood back up, leaving her lower region completely naked and ready to be taken by his hot throbbing shaft.

“You have come a long way,” Thunderlane commented with a humoured voice as he snaked his free hand under the horny princess’s thighs, before lifting it up and placing it over his shoulder, giving his cock a free line to bury itself into her juicy crotch.

“I-I can’t help it!” Twilight whined, squirming in his grip, “Y-You know h-how my heat gets!”

Thunderlane simply smirked at her with a raised eyebrow, “Oh? Are you sure it is really just the heat? Or could it be that you are just a needy slut?”

“I-I-I most certainly am noaaAHHHHHHHHHHHHH~” the lavender mare tried to protest, but was cut off as Thunderlane simply shoved his length completely into her in one fluent thrust. Spreading the well-used lips without trouble and gliding effortlessly into these dripping needy depths. Twilight couldn’t help but pant heavily from this rough and forceful insertion.

“B-By C-Celestia! I-I needed this!” she stuttered out in ecstasy, enjoying the feeling of having her hot needy twat speared by his majestic meaty pole, practically stretching her wide and even without revealing his true length.

Thunderlane could only grin at the slutty princess as he pulled his hips all too slowly and teasingly back, making her gasp in anticipation, as well as squirm as a sudden emptiness was creeping up on her love canal, before Thunderlane then released her as he drove his thick cock back into her and without mercy.

Twilight couldn’t help but squeal out loudly, pleasure overtaking her mind like a drug as she braced her hands against the wall of a house for balance. It was a wise decision considering that Thunderlane didn’t even give her time to adjust as he started to fuck her hard from the beginning. Not that Twilight protested. She needed this. She needed it hard and forcefully. For this hunk of a stallion to dominate her frame and make her his. The taboo thoughts of this action alone made her walls clamp and clench all too frantically along his large cock, enjoying each vein on it that so teasingly rubbed her cunny.

The sideways position she found herself in made it only more arousing for her, as her whole body was on full display for anyone that would walk past the alley, if it wasn’t for the illusion she had placed down.

Each wet smack splattered some of her sticky juices on the ground, showing just how much enjoyment the slutty mare received from this, and also how high her libido has become. The sounds of her continuous spurts was also a huge turn on for Thunderlane who felt his balls getting positively drenched every time he buried his shaft completely into that wet snatch.

What baffled him from his time with Twilight was that he was still holding his true length back and she already had such an extreme reaction. It just showed how adjusted the two of them were to each other and how much Thunderlane had shaped her pussy with his cock. It was quite the arousing thought, though it would be even more arousing to send the mare he was fucking delirious with his true length once again. So, he gave the alicorn a teasing grin.

“So, is my little Princess Slut ready to take on the full dose of my vitamin D?”

Twilight herself escaped a whimper as she heard that Thunderlane was about to get serious, “P-P-Please,” was all she managed to stutter out in her pleasurable haze. There was nothing more needed.

Thunderlane simply gave her a saucy grin, before he grabbed her other leg, and throwing it over his shoulder, so that Twilight was now positioned with her back to the wall. She yelped briefly at being repositioned, but it was nothing compared to the volume of the squeal as she felt the cockhead that was buried at her entrance expand.

Immediately her outer pussy lips were stretched to the max as she felt Thunderlane release his monster of a cock. Twilight herself couldn’t help but jizz herself at the sensation as her whole body was wracked by the pleasure his mighty tool brought her.

Thunderlane didn’t even wait for Twilight to recover as he thrusted his spear into her without mercy, letting the slutty alicorn be impaled on his shaft. His rock-hard cock met no resistance as it practically battered the entrance of her womb open in an all too rehearsed fashion, hilting his cock there for a moment to enjoy the feeling of this hot inner sanctuary. A sanctuary he has defiled oh so many times with his cock and seed that he even had to wonder if it could be called sanctuary anymore.

Twilight meanwhile was in hysterics, her body going in another mind-numbing orgasm, as her whole body simply spasmed as Thunderlane pressed her with the full might of his cock against the wall behind her.

She only got out of this state when Thunderlane started to pound her naughty wet snatch again. The lavender mare was gasping as his tool was pulled out all too teasingly, before squealing loudly as it was stuffed back in to the hilt.

Thunderlane meanwhile changed the position as he took the legs from his shoulders and to the sides of his hips. Twilight reacted immediately as she needily wrapped them around his waist, not willing to ever let his cock go. Her arms followed as they wrapped around his neck, making her feel his hot breath on her neck, sending a shudder of pure bliss through her thoroughly fucked frame.

Her legs seemed to tighten as Thunderlane lurched forward again, encouraging each of his hard thrusts into her dripping wet twat. And how wet it was!

Each time their hips smacked against each other a wet squelch could be heard as Twilight’s juices covered them both by the hips, making Thunderlane’s cock, balls and thighs practically stick to her perverted frame wetly, while the rest simply continued to make a wet puddle on the ground.

With the pace at which Twilight was losing her juices, Thunderlane knew she would need a drink to regain them, and he had already an enticing idea for that.

“Ready for the big finale, my Princess?” Thunderlane teased, making the lavender mare twitch.

“YES! GIVE IT ALL TO ME!” she practically screamed and begged, making the pegasus stallion grin.

He then sped up, his hips a blur, sending Twilight over the edge again with no problem. Though he didn’t stop or show any signs of slowing as his throbbing length simply punched into her again and again, forcing a second orgasm in row to follow and driving the lavender mare delirious as she stuck her tongue out in a continuous scream of ecstasy.

Though what she didn’t expect was for Thunderlane to pull out just as he had gifted her with her third orgasm in a row. She couldn’t even react as Thunderlane had pulled her legs around his waist loose, lowering her to the ground with her legs widely and lewdly spread.

Then without waiting for her reaction, he grabbed her mane and drove his enormous cock into her mouth. His hot throbbing length plunged right through her throat until it rested in her stomach.

Twilight felt his crotch press against her muzzle, making her forcefully inhale his strong musk, making her body quiver in need as her orgasm still tore through her mind, practically frying it as her pussy lips frantically grasped against a shaft that wasn’t there, while gushing out a huge torrent of her juices.

Thunderlane used her deliriousness to pull her on her mane, thrusting his shaft in and out of her, giving the alicorn princess a hard facefuck and smearing her own wet juices all across her muzzle.

His motions didn’t remain long however as he soon hilted himself inside her stomach once again, but this time lingering there as he decided to empty his balls directly into her.

Twilight could only helplessly gurgle as she felt volleys of cum travelling down her bulged neck and into her stomach. The wet sloshing of cum filled her stomach, painting it in his white seed, and marking it as Thunderlane’s personal property.

Twilight’s belly slowly started to expand, giving her a noticeable bulge, before Thunderlane decided to pull out. On the way he also gave her throat a nice new coating, as well as her mouth as he lingered a moment there to fill her up.

As soon as he had pulled out of these luscious cock-sucking lavender lips he aimed his meaty pole at her face.

Twilight didn’t protest as she felt his hot sticky cum staining her face and mane, marking her as his mare. He didn’t even stop at her clothing as her shirt and skirt were soon drenched as well in his stuff.

As soon as the alicorn was marked as his personal cumdumpster the flow tapered off, making Thunderlane sigh in satisfaction. The mare before him now was a perverted art, a painting with streaks of cum all over her, one even dangling all too obscenely from her horn, while her filled mouth was drooling his spunk freely, making it drop from her chin and dripping to her defiled short skirt below.

Thunderlane then stepped forward, pulling some of her clean mane from behind her before using the soft silky strands as a towel to wipe his cock clean on her.

After that he stepped back, making her hair fall back against some cum splotches on her arm and shirt.

He was really glad that Twilight turned out to be such a perverted mare, and helping her with her needs certainly has come to be a very enjoyable pastime. Especially considering her magical abilities. He could leave her there in the alley without problem as her illusion still held strong, and he didn’t have to worry about some bukkake action since she could teleport herself straight to her bathroom. So her being an all-powerful alicorn certainly had its upsides, besides the obvious one that she could take his full length.

Thunderlane then pulled her drenched panties from his pockets, showing it to the still delirious mare whose legs were occasionally twitching.

“I will take these,” he simply stated with a saucy wink, before pocketing his souvenir once again and making his retreat back to his home.

Twilight could vaguely see Thunderlane take her dripping panties with him. Not that they would have done much to help her from leaking anyways. It was pretty much something Thunderlane loved to tease her with. The stallion wanted her to go commando, but Twilight until now was still too embarrassed to go through with it. But her inhibitions have been broken down in huge steps over the past month, and she was sure that her determination would break this very week. Just as her determination would break on the point that she still refuses to wear an egg vibrator in public.

It actually sometimes made Twilight wonder why she fought against this bliss if she knew she would eventually give in anyway. Though she concluded it was probably the side of her rational mind trying to save her dignity, or what was left of it. At this point, she didn’t know if there was even any dignity left to save. Not that she cared as she sat in a puddle of her own juices on the ground, her eyes rolled back to her head as she was practically beaming from the blissful feeling of her afterglow.

An hour later the train in Ponyville arrived. The doors opened without any hindrance as the different passengers left the train, or entered it. Among the passengers leaving the train was a familiar pegasus guard with orange fur and a blue mane.

The figure had a smile on his lips as he eyed the crystalline structure in the distance and made his way towards it with an upbeat gait.

It was time to see his marefriend again.
