[TG] Thirsty

Tier Reward for Matthew Knuckles

A man gets caught sneaking off to a seedy porno shop by his girlfriend and gets transformed into a cum hungry whore. 

~

The room was small and dank; the dusty old curtains that blocked the view inside from the windows meant no natural light could come in. As a result, the room always looked vague grey and shadowy. The shelves were so ancient it was a miracle they hadn't fallen apart and the paint on the walls was chipped and peeling; the parts that were bare that is. Most of the walls were covered head to toe in posters; some faded and ancient, others new; all lewd. Each showed a woman with a face full of ecstasy as she danced around a pole or posed on a bed. All in all, the porn shop couldn’t have been more stereotypical if it tried and that made Natalie all the angrier.

This was the place her boyfriend had been sneaking off to? She almost wished he’d been cheating on her, that would have actually been easier to respect. She grimaced, looking at the lines of neglected magazines and walked the aisle down to the video section. There was a little register sitting on a desk, behind which sat a man who looked wholly uninterested in her; he obviously knew she wasn’t here to buy.

“If you’re looking for your man he’s probably in one of the booths.” The man behind the register said in monotone without looking up from his playboy issue. “If you’re gonna have a screaming match do it outside, people are trying to have a good time.”

Natalie sneered at him, her magic boiled beneath her skin but she kept it in check. She would need every ounce of it to punish Jack when she found him. 

The back of the store had several small rooms with curtains separating them from the main area. Behind the thick fabric she could hear muffled moans and the static of old TVs, along with the telltale sound of live grunts and the occasional slap of skin. Masturbation rooms; lovely. The sound of a familiar groan made her ears prick; he was here. With her temper rising Natalie stalked over to the booth where the sound had come from and flung back the curtain to reveal her boyfriend, spread out over a dusty couch with his hands in his pants, eyes on an old CRT monitor and a busty blonde.

“You bastard!”

“Natalie?! What the fuck, you followed me here!?”

Jack was scrambling, wincing as he stuffed his stiff cock back into his pants. On scream the blonde was moaning;

“Oh please give me cum, I’m so thirsty and it’s the only thing that’ll satisfy me!!”

“This is the sort of thing you like?” Natalie scoffed, ejecting the tape and taking in the label. “‘Cum Guzzlers’?” 

“Look, you won’t do some stuff, it’s not like I am cheating or anything.”

“I sleep with you plenty, just because I won't beg you for your cum doesn’t mean you can go and hang out in a dump like this!”

“Stop acting like I am doing something awful.” Jack crossed his arms. “It’s just porn.”

“Well, if that’s the sort of stuff you like, you can go live it to your heart's content, without me!”

She snapped her fingers, letting her magic burst forth in a silent beam that struck Jack straight through the heart. Not that he knew; her spells were silent, as far as he knew she’d just clicked her fingers for emphasis. But the job was done, Jack was cursed and soon he would be compelled to act just the way Natalie wanted. Or rather, how her magic did. 

“Fine, you were crap in bed anyway!” Jack cried and Natalie stamped her foot in a huff, storming out of the dank old shop with her nose in the air and a triumphant smile on her face. 

“By the time you get home I’ll be long gone!” She yelled over her shoulder before slamming the door.

“I told her no arguing in the store.” The manager said, again in monotone. “One strike against you Jack, three and you’re out.”

Jack just rolled his eyes.

“Don’t worry, she won’t be coming back. Speaking of cumming, I’m going to keep watching my movie.”

The manager just shrugged and turned a page of his magazine. Jack settled himself back down in the booth; still annoyed and more than ready to relax with a little self care. Natalie hadn't been a great girlfriend anyway, so vanilla, it was boring. Not like the girls in this film, they were up for anything. 

Jack put the video back in and clicked play, ready to watch. The blonde laid in the middle of the bed, jacking off two guys on either side. With loud groans they both came and the woman opened her mouth to swallow as much of the white streams as she could, getting a full facial in the process. 

Jack groaned and stroked, trying to imagine himself standing over that woman and cumming down her throat. For some reason though, it just wasn’t working for him anymore, Natalie must have ruined his mood. No, that couldn’t be it. He was still horny as hell, but imagining a girl swallowing him down just wasn’t as enticing as it usually was. 

Instead his mind drifted, imagining how good it would be to be in the woman’s position. Swallowing down the hot, thick cum, feeling it drip down his throat…fuck, it was turning him on so much. His cheeks flushed with embarrassment but he couldn’t help it, his mind was going wild with fantasies of swallowing cum. The idea was getting him more and more turned on but for whatever reason, he just couldn’t finish! 

Groaning in sexual frustration he stopped to let his wrist rest. The video had finished ages ago and now the DVD menu was just looping on screen. The image of that woman on screen was burned into his brain though. Just then, he heard a sound, the low groan of a man cumming in the booth next door. 

The sound sent a shiver down his spine, Jack was sure he could even smell it. Before he knew what was happening he was up on his feet and passing a man exiting the next door booth. Without even glancing to see if anybody was watching, Jack snuck into the booth and saw it. A viscous white stain on the chair. He was on his knees, lapping it up before he could stop himself.

“Mmmm, oh fuck what am I doing but uhhhh it tastes so good!”

His body shuddered as pleasure passed through him; Jack was sure he was cumming, but for some reason he wasn’t cumming. A shame, because the little stain wasn’t nearly enough, he needed more.

Suddenly the curtain pulled back and Jack blinked in surprise as a burly looking man stepped inside, looking shocked to see somebody else already occupying the private booth. 

“Uh, sorry.” He muttered, turning to go.

As he did so, Jack caught sight of the DVD in his hand and his stomach lurched. It was a gay porno, this man was into guys and that meant…he might be able to get some more cum. God, the idea of sucking another man off was so embarrassing and yet, he couldn’t help himself. He was obsessed. 

Before he could stop himself his hands were resting on the burly man’s belt and pulling him back inside.

“I’m much better than any film.” Jack whispered, face flush with humiliation and need. 

The man opened and closed his mouth in shock, looking between Jack and the DVD in his hand as if weighing the options. 

“Please.” Jack hated how desperate his voice sounded but he just had to get more cum. 

“Go on then.” The man grinned, “Who am I to turn away a willing mouth?”

Jack could feel his lips growing wet as his mouth watered and the man undid his fly. Oh God was he really going to do this? There was a glistening drop of precum beading on the tip of the thick length and that was all the convincing he needed. Before he could stop himself his tongue was licking the drip, moaning at the salty taste and sliding the cock along his tongue. 

He had no idea how to give a man a blow job, but he knew what he liked and tried to copy it, swirling his tongue and bobbing his head until the man’s balls began to twitch. Without warning a hot stream of cum was pouring down his throat; so fast Jack couldn't even take a moment to savour the taste. 

He moaned, his whole body felt tingly; it was pleasurable but there was something else. His lips felt poutier, and his hair a little longer, long enough that the man was able to grip a handful of hard as he finished. Jack continued to suck and swallow, trying to get every drop possible before the man finally pushed him off with a gentle hand. 

“Fuck, that was great.” He groaned before looking at Jack quizzically. “You know, I don’t usually go for the femboy type but you were pretty great.”

“F-femboy?” Jack choked, but the man was already leaving, DVD forgotten on the floor. “What did he mean femboy?”

Jack got to his feet and wobbled, his shoes felt slightly too loose all of a sudden but he brushed it off. Stepping back into the shop the manager looked up for the briefest of moments before muttering.

“If you see anything you want just let me know.”

Jack felt his brow furrow; he came here all the time, why didn’t the manager recognise him all of a sudden?

“Bathroom?” Jack asked, the manager shoved a thumb over his shoulder.

“But if you want private time the booths are better.”

Jack ignored him, running straight for the bathroom to get some answers. The mirror was a bit dirty but the second he saw his reflection jack felt his jaw drop. No wonder that man had called him a femboy; he looked utterly different! His lips were pouty, his hair an inch longer and his features seemed slightly smoother and more delicate. He was still obviously a man, but a pretty looking one. What on Earth was happening. 

The sound of voices made him turn just in time to see another young man walking in the door, magazine curled up in his hands and looking back over his shoulder.

“No thanks! Those curtains don’t look very private!” 

The man turned and took a step back in surprise to see the space already occupied.

“Then again.” He sighed. “You going to be long? I’ve had a hell of a week and no luck at the bar.”

Jack found his mouth watering once more when he realised what the man was implying. He wanted to resist, wanted that blow job to be a one time humiliation but his body almost felt like it was being pulled on a physical cord. He couldn’t taste the cum from the first blow job anymore and it was torture. He fell to his knees before he could stop himself, desperate, his throat burned with need like he was dying from thirst. 

“Woah dude, what are you doing?!”

“I’m sorry, I can’t help myself.” Jack moaned, pawing at the front of the man’s trousers where a bulge was slowly forming. “Please let me suck you off, I need to taste it…”

The bulge grew bigger and the man smiled widely. 

“Well if you’re desperate…”

He pulled himself out and Jack was on him in an instant, sucking down the length and squeezing his balls in an effort to produce more for him to drink. 

“Oh fuck! Oh wow uh..uhhh! Oh fuck I ain’t gonna last-!”

It took barely a minute until that lovely cum was coating his tongue, this time he made sure to savour the flavour before gulping it down loudly with a groan of satisfaction. That warm fuzzy feeling inside him grew and expanded. Jack could feel his chest swelling as two pretty tits formed there and his ass began to weigh him down. With every swallow, Jack could feel his body becoming more feminine and yet he still couldn’t stop. 

By the time he’d sucked the guy dry his whole body shape had changed to something more hourglass inspired. Luckily for him, the man whose cock he’d just sucked was so blissed out from the intense orgasm he didn't seem to notice. Just stumbled back out into the shop with a pleasant, vacant smile on his face. 

“Oh fuck, what’s happening to me?” Jack said as his new chest heaved. “Why do I have tits!? Oh God, why do I want more?”

Even though he’d just sucked off two different men he still felt thirsty, not for water but more seed. Fuck, he could remember the face of that woman int he video and the look of ecstasy on her face as the white fluid soaked her. Jack wanted to be her so badly right now. He still had a few traces of masculinity but he was definitely looking more like a woman now. Maybe if he could stop himself from sucking another cock he would change back? 

That was easier said than done though, even after leaving the shop to walk home he felt that burning need inside him. Every man on the street that he passed looked enticing and he swore he could smell that heady, salty scent in the air, drawing him in. His hips swayed now and his feet clicked as his sneakers transformed into a pair of long high heels. 

“C’mon babe, just one round?”

“I ain’t getting on my knees for less than fifty, get lost.”

Jack froze on the spot as the words floated out of the alleyway. A woman dressed in a tight fitting miniskirt and tube top stormed out, followed by a dejected looking college guy holding a twenty dollar note and sporting a bulge in the front of his pants. 

Jack’s breath caught in his throat. The man was young, with curly hair and a freshly shaven face, not bad looking by any means, but clearly down on his luck. Their eyes met and Jack felt like a deer in the headlights as eyes roamed over him. 

His jeans and shirt had changed at some point, he had no idea how. Now he was dressed in a tight fitting leather mini dress with big golden hoops poking out of his ears. The dress hugged his figure and pushed up his small breasts. He didn't look half as womanly as that hooker, and his face still had some boyish features to it, so the young guy didn’t look super impressed. 

“Don’t suppose you’re on the job?” he asked half heartedly, “I just want a blowjob.”

Jack felt humiliation welling up inside him; this guy thought he was a hooker! He opened his mouth to say no but then froze, the hunger was there. The desperate need for more cum and the temptation of it being right in front of him. Jack nodded.

“I’m Caleb.” the man grinned, “Come on, back here, do you have a name?”

“Jack.”

“Jackie?”

“...sure.”

Jack felt himself getting tunnel vision; this Caleb could call him whatever he wanted if it meant he got what he needed. Jack took the cock lovingly into his mouth and began to bob, gripping both of Caleb’s hips tightly as he sucked and swallowed; deep throating him as much as possible. 

Just like before he was rewarded with a stream of hot cum down his throat and in response his boobs began to grow. Caleb howled as he came, something that made him quite flustered as he awkwardly handed over the twenty and fled the alley. Luckily for Jack, somebody had heard them. A male somebody. 

He stopped hesitating, unable to resist the allure of cum. He swallowed down more and more, sucking off every man who was drawn to the sounds of ecstasy he could elicit. His butt swelled, his breasts doubled in size until they were almost falling out of his dress and his blonde waves now brushed his back. Nobody would ever guess that a few hours ago he’d been a man. 

Jack couldn’t even bring himself to pretend he wanted anything different; couldn’t force himself to feel ashamed anymore. This was just too much fun and he loved the sound of his heels clicking against the concrete as he went in search of new men in need of servicing. No matter how much he drank, there was always room for more. 

From the shadows Natalie watched with a superior smile; she had intended to switch Jack back once he’d learned his lesson but he was having so much fun she didn't have the heart to do it. He’d never worked so hard in his life; if anything this was his calling and who was she to keep him from it? 

~

At first, Jack had been worried about whoring himself out to satiate his need for cum but the stars aligned for him pretty swiftly. The dusty old porn shop had never been more popular since he took up residence. Soliciting on the street had been risky, safety wise. Some men were rougher than he would have liked and Jack realised he needed a way to keep up his supply without putting himself at risk; so he’d started to sneak into the porn shop booths and present himself for willing men. Once the manager caught on he’d thought it would be game over but on the contrary, he was more than happy to let Jack suck his clientele off. 

The manager even gave him room and board; for a fee of course. Not a monetary one, but one of sexual favours. Which as far as Jack was concerned, was a win-win. If Natalie had put this curse on him to try and ruin his life, it hadn’t had the desired effect. He’d never been happier!

He had a stable job, a roof over his head and all the cum he could ever want to drink! It was incredible. More customers than ever came to the shop too, so the manager was able to make it look less shabby. 

“Maybe I should hire more girls like you.” He said one day after they finished closing up in the wee hours of the morning. “I never fancied myself a pimp but this partnership seems to be working out well.”

“No.” Jack said sternly, “No other girls, I wont have anybody muscling in on my turf.”

The idea of having to share the cum around with other women….no, he wouldn’t allow it. 

“But you can’t service everybody-”

“I will, I’ll suck twice as much dick if that’s what it takes.” He said defiantly, “I’m not sharing.”

The manager just chuckled.

“Have it your way.”

Jack had the distinct impression that he may have just been manipulated but he didn't care. If anything, getting to suck more cocks will mean more cum and that was the most important thing. 

The little bell above the door tinkled and in walked a handsome but irritated looking man. He had that stiff look about him that was a dead give away that he hadn’t had any good sex in some time. His hands fidgeted with magazines and his eyes darted around; a first timer; with looks like that he probably wasn't used to dry spells and now this shop was his last resort. 

“Can I help you?” Jack asked with a knowing smile, stepping out from behind the shelves and making him jump. 

“Uh, just browsing.”

“You don’t look like you want to be browsing.” Jack laughed before taking his hand and gesturing to the booths. “Want something more…lively than a magazine spread?”

The man’s face broke into a grin. 

“I’d heard rumours…Harrison, by the way.”

“Harrison, nice to meet you, I’m Jackie, why don’t you come with me?”

Harrison was already half hard by the time we reached the booth; Jack could smell him in the air and his mouth started to water as he unzipped his fly. Jack got down on his knees and reached out to stroke the length to full hardness then licked his lips; it was time to do what he did best.
