Even in the closest and most open relationships the sex often has lingering inhibition, holding back, or at the very least, some modified behavior to take their partner’s preferences into consideration. After that first night, Soarin displayed that same kind of restraint while fucking the now-enslaved Thunderlane as he had when they were a normal dating couple. After all, despite his glee, he still looked out and saw the face and body of his ex-coltfriend, and even knowing that Thunderlane was now his own personal property, it took some time for Soarin to loosen up.

Once Soarin started to loosen up, Thunderlane saw a whole new side of his ex-coltfriend, qualities he’d never known were there. Of course, he saw them as he looked out through the small windows of his eyes because he was trapped, captive in his own head, and Soarin slowly became used to the idea that when he fucked Thunderlane, he wasn’t having sex at all, but using a new fuck-toy to masturbate.

The moment that sunk in, Soarin really cut loose. He treated Thunderlane like a toy, something he used to get off.

Thunderlane was no longer allowed to sleep on the bed, instead, he was forced to sleep on the floor beside the bed. Every night Soarin would wake up Thunderslut by yanking his muzzle open and jamming his cock down his throat. Thunderslut would barely be able to breathe while his tongue, mouth, and throat went to work coaxing another big load of stallion spunk out of his master's cock.

Once he'd pumped his pet's 'late night snack' into his stomach Soarin would go back to bed without so much as a second glance at Thunderslut.

A few faint whimpers could be heard from Thunderslut as his own member throbbed in need of release, but once it was obvious that Soarin was fast asleep again, he would resign himself to curling up and getting what little sleep he could get before Soarin would wake up in the morning and torment him some more.

Mornings had become a depraved routine as well, waking up smothered by Soarin's flanks wrapped around his muzzle Thunderslut would happily extend his tongue out and begin to rim that delightful ponut. His tongue worked in circles around his master's puffy anal ring, eliciting groans from Soarin that were muffled by Soarin's hind legs being wrapped around his head tightly.

“That's it sweetie, eat my ass, you're going to be doing this every morning for the rest of your life,” Soarin taunted.

Thunderslut felt more pressure being put on his skull as Soarin let more of his weight down onto his pet's muzzle, Thunderslut took that as a signal to start probing his tongue inside Soarin's rectum. He wiggled his thick tongue inside Soarin, the taste overwhelming Thunderslut for a moment before the enslaved butt eating stallion carried on.

Soarin closed his eyes and shuddered, enjoying the sensations. He leaned forward with a sadistic smile and grabbed his slave's throbbing cock with one hoof. He gave it a firm squeeze, causing Thunderslut to moan directly into his asshole. He stroked his pet's stallionhood, knowing that each stroke brought his pet closer to another cruel and mercilessly denied orgasm.

“What's it been now...Almost 3 weeks without release? I'm sure you'd be begging and crying to let you cum if I'd let you.” Soarin said with a groan, Thunderslut's muffled bark caused vibrations to ripple across his sensitive prostate. “I've got a special surprise for you tonight too... I might even let the old you stay out and play!” Soarin's cock exploded, the combined pleasure from Thunderslut's rimming and the thought of his plans for the evening sending him over the edge. Five solid streaks of jizz flew through the air one after the other and landed on Thunderslut's stomach fur, causing it to become sticky and matted.

Soarin slowly stood up, legs wobbling slightly as he panted to catch his breath. He looked over at the clock, taking note of the time. “Oh no, it's getting late, no time for you to clean yourself up before work again. You're going to have to leave now, just so you won't be late... Oh don't forget the lunch I made for you, It's in the fridge.” Soarin laughed.

“Yes, Master,” Thunderslut replied.

Going to work used to be something Thunderlane actually enjoyed, but now it was just another layer of hell he was forced to live through. He went from obedient submissive pet-slut enduring the constant sexual torment Soarin put him through at home, to being forced to turn back into a shell of his former self and go to work. Each day trying hard to tell somepony that he needed help, that his coltfriend had him brainwashed and under his control.

Unfortunately for Thunderlane, Soarin had everything covered. With a few well-chosen orders, Soarin crafted Thunderlane a persona for work. Working-Thunderlane was cheerful, friendly, a hard worker, never spoke badly about anypony, and did his job well. And, of course, he never commented on his home life, he kept to himself, politely refusing any invites to social engagements from coworkers, and absolutely never mentioned anything about Soarin. Thunderlane had been closeted at work back before the brainwashing anyway, so it was easy enough just to continue with that.

No pony noticed any physical changes with Thunderlane either, A strong perception charm powered by the magical mind-controlling microchip inside him made it appear to anypony other than Soarin that Thunderlane looked the same as he always had. The dirty cum-stained matted fur and painful throbbing leaking erection of Thunderlane went unnoticed. It was why Soarin always happily used him as a cum-rag each morning.

Lunch hour would arrive, everypony would take a break from busting clouds and sorting out the weather for the day to grab something to eat. Thunderlane had begun to bring a thermos from home in for lunch every day. He'd sit down with some of his coworkers and watch them as they ate hayburgers and sandwiches. All the while he was forced to open his thermos and happily glug down a chilled thermos filled with his master's cum. It was the only thing he was allowed to 'eat' now, “A strict cum only diet.” as Soarin called it.

If he had any control over his body, Thunderlane would be retching and gagging from the taste, but Soarin had him programmed to love the taste. A warmth would wash over his body as the thick sticky liquid slowly rolled across his tongue, down his throat, and into his eagerly waiting stomach. The taste would linger in his mouth for the rest of the day.

“Hey, Thunderlane,” Cloud Chaser would say, in between bites of her lunch. “How's it going?”

“It’s awful!“ Thunderlane would try to say, ”I’m living in a nightmare! My asshole ex-coltfriend had me brainwashed and now I do what he says, and he’s a nymphomaniac who just fucks me all day long, I haven't cum in three weeks and I've lost count of how many orgasms I've been denied. He took everything from me and makes me work to earn money just to torment me. Please, please help me!“

As he tried to mouth the words, of course, he’d instead smile. “God, I’m doing great,” his mouth would say, “I’ve been really feeling really awesome lately. I don’t even know what it is!”

“Well, whatever it is, if you find out, let me know.”

“Ha! I definitely will.”

And off he would trot, like a cheerful robot, back to doing his job.

Everyday work would end and he'd be ready to go, jumping up into the sky, and fly back home. No matter how many days passed, it never got easier, the sense of dread filling his mind as he landed gracefully in front of his home.

Now it was more like a prison.

Bondage had always intrigued Soarin, the aesthetic of it really made his cock throb. To see somepony struggle against their bonds and know that no matter how hard they tried to escape, they were at his mercy always made him shake with anticipation.

Before things changed, Thunderlane was completely opposed to any kind of fetish play in the bedroom whatsoever. Now, he had no choice.

Soarin was in the bedroom setting everything up when he heard the front door open and close. “Thunderlane, come up to the bedroom.”

“Yes, master,” came Thunderlane's reply.

Soarin watched as Thunderlane walked into the bedroom. “You may speak freely... but no yelling.”

Tears started to well up in Thunderlane's eye's a mix of anger, fear, and yearning for release buried his mind in emotion. “Please... Let me go, You've had your fun, I promise I won't tell anypony. Just let me have my life back.” The waterworks started to trickle down his cheeks, a hushed sob working its way out of his muzzle. “I don't want to be your slave, my dick hurts, and my balls ache so badly... I want to cum, I want to live a normal life again.” Thunderlane couldn't hold back the tears any longer, he cried and pleaded with Soarin.

Soarin walked up to Thunderlane and grabbed his face with one of his wings, Thunderlane tried to shy away, but Soarin turned his face so the two were making eye contact. “Aww sweetie, don't cry.” Thunderlane's tears and sobbing stopped. “You're stuck like this forever... Life is too perfect for me now... I fuck my little obedient cock slave every morning and night and still collect a nice chunk of bits from being a reserve Wonderbolt, and you make a fair share of bits working as a Weather Pony. Your money even paid for the fun night we're going to have, just look!” Soarin stepped to the side, allowing Thunderlane to see what his captor meant.

“No, no, no, no, no, please don't.” On the bed was a wide variety of toys and bondage gear. Butt plugs, vibrators, chastity cages, shackles, ropes, gags, and plenty of other things Thunderlane had no idea what they were but they looked intimidating nonetheless.

“Yup! Sometimes you spoil me,” Soarin laughed as he pat Thunderlane on the head. “I think tonight I'll let you stay out and play, give Thunderslut the night off... Celestia knows, he earned it. Hahaha”

Soarin walked over the to bed and picked up a butt plug, it's width clearly wider than Soarin's cock. “You see this one.” He clicked a button on the bottom of the base, causing the plug to vibrate wildly. “You'll be wearing this one to work every day. It should rest right up against your prostate, causing even more painful denied orgasms.” Soarin clicked the plug off and set it down, grabbing the chastity cage next. “This thing is kind of redundant since I already control your orgasms, but if you ever piss me off this thing can be hooked up to an elctro-stim meter...” Soarin picked up a small electronic box showing it Basically I can shock your dick, turn you into a pain-loving slut, or just torment you until I think you've learned your lesson. Just a helpful little reminder so you don't forget your place.”

Thunderlane started to shake, his pupils turning to pinpricks. “Please don't make me endure this... Just lock me back in my brain, please,” he pleaded.

“Hahaha oh no sweetie, If you're going to beg like this, I think I'll have more fun with you like this than with Thundeslut.” Soarin picked up a thick black leather collar and cinched it tightly around Thunderlane's neck. He cleared a space on the bed, moving everything out of the way, he gestured to the end of the bed. “Come over and lay down with your head hanging off the bed.”

Thunderlane tried his hardest to keep his body from moving, but in the end, he found himself unable to disobey Soarin's order. “Yes, master.” He laid down just as Soarin asked, his head hanging off the bed and facing the ceiling. He watched Soarin get to work,

“Open wide, sweetie.”

Thunderlane opened his muzzle and felt a ring gag placed inside, the strap was tightened around the back of his head, just tight enough to be uncomfortable as it dug into the back of his head. Drool started to leak out of his mouth, Soarin grabbed a few large straps and quickly had Thunderlane restrained down on the bed.

“Go on, try to break free.”

Thunderlane wriggled and squirmed as hard as he could, the straps clearly serving their intended purpose. He couldn't move an inch, Thunderlane wanted to scream...cry...escape... anything at this moment.

“Good,” Soarin bit his bottom lip. “You look so fucking hot tied down, unable to move, with a ring gag in your mouth, ready to throat my cock... Just a couple more things and you'll be perfect.” Soarin added a few more items to his bound little pegasus slave. Vibrators were attached to the head and shaft of Thunderlane's cock, turned on to their second highest setting. This caused pre to start leaking from his throbbing cock, the closest he ever got to release now.

“Perfect!” Soarin said as he straddled his pet's head, the tip of his cock poking through the ring gag. With a harsh thrust, he drove his cock deep down Thunderlane's spasming throat his ballsack slapping against the gagged pegasus's forehead.

“You've got a long weekend ahead of you, honey.”

Author's Note

Ideas cut due to 'time constraints' (Me being lazy/feeling repetitive/didn't feel like I could find a good way to end if added.) 😂

-Drippy Dick Torture: Thunderlane bound in a way that forces his precum leaking cock to drip directly into his mouth for the rest of the night.

-More Anal and Blowjobs: I mean It kind of felt repetitive to put it in with just the additional 'bondage' spin

I welcome and encourage any and all complaints about this chapter/story as a whole.

With the one exception being "You wanted a 'Good' ending". Because that was never fucking happening. 😂
