Castle hated jobs like this. "Cheating spouse" jobs were the lowest PI work there was, and he only took the job because work had been very slow and he just needed something to do. He regretted it almost immediately, even more so when he got pics of the wife fucking a huge cocked Latino man and knew the husband would be furious. Susan's face was nothing special and her nose was a bit large, but she was very muscular and could have been a fitness model if she had bothered. Castle remembered watching her muscles flex and move under her skin as she pushed back against her lover. She had lost so much body fat that her tits were almost gone, but her overall look was that of an expensive woman. She looked like money. She was incredibly attractive, no doubt about that.
Now, with pictures on the table, the husband was raving mad. Stephen Dobson was a very successful and wealthy movie producer and Castle got the feeling the man didn't take disappointment well.
Castle tuned out the man's ranting and thought about how much he hated these jobs when the man asked him a question.
"I'm sorry, what was that?"
"I want her to pay. I've heard you have some seedy connections, that's why I picked you. If she likes Mexican cock, I want her to get so much she never wants it again. I want her to pay. I want that fucking bitch to..." The man went on, but Castle starting tuning him out again.
When his client's steam ran out, Castle said, "I can make it happen. If you want her getting fucked until she regrets her affairs, that's easy. But it will cost a good bit, and most importantly, she won't be the same after. She'll be permanently damaged both mentally and physically. Do you really want that? It would be cheaper and easier to just divorce her. Anyway, I want you to take a few days to think about it. If you are serious, call me on Saturday."

Saturday: "I want her to pay."

Tina's pussy was pleasantly moist as Castle jerked his cock off in her numb hole. A few months back, they had discovered Tina could come with her asshole if they abstained from anal sex for a week or so and then Castle gently worked her up to an anal orgasm. He had settled on what he thought was a hilarious plan to help her cum. For a week or so, he would abstain from her primary fuckhole and would use only her pussy and mouth to empty his balls. Tina didn't know it, but once every three months Castle would drug Tina and shoot her clit up with botox. So she could barely feel the pussy fucking, but she could feel it enough for the vaginal sex to tease her mercilessly. She would writhe around panting and desperately trying to get off as Castle stroked in her tight cunt, but ultimately he would shoot into her and leave her a sweating and frustrated mess.
He loved it.
Tuesday morning, exhausted from her overnight shift, Tina lay on her back sweating and frustrated as Castle rode her in missionary, enjoying her clasping pussy around his fat cock as he sucked on her neck and frenched her mouth. After some time, he picked up steam until he was roughly pounding her while pinching and slapping her tits. Finally, Castle leaned over and roughly crushed a bulging tit while he bit into her neck and had a very satisfying cum deep in her pussy.
After catching his breath for a few seconds, he rolled off of her and said, "Only five more days, then you get to cum. Are you excited?"
She lay there panting and silent. After their years together, Castle knew she was in deep inner turmoil. He could almost hear her thoughts as his lesbian girlfriend struggled with her desperate need to cum and the fact that she could only cum from anal sex with Castle. She had tried sex with women multiple times, but even with a strapon they couldn't get her asshole off. So far, only Castle could do it.
So, of course, he used that fact to humiliate and manipulate her.
Castle built it up to Tina that the week of anal abstinence was not something Castle was enthusiastic about, so he made Tina earn it. This week would be her second orgasm in the three months since Castle figured out how to make her cum, and Tina was desperate for it.
For the last two months, Tina had done everything for Castle. She made him dinner, she cleaned his apartment. She sucked and fucked him whenever and wherever he said. But during this week where she was earning her orgasm, he had humiliated her without hesitation or mercy. She lay there panting, thinking of horrible memories.
...Castle waking her up from a deep sleep during lunchtime for a quick fuck. Tina grunting in pain as Castle grabbed two handfuls of hair and brutally smashed her pussy until he came in her...
...Castle again with two handfuls of Tina's hair, but this time using them to fuck her head on and off of his cock. He didn't let up the pressure as his cock reached her throat, and he groaned in pleasure as her throat opened in his cock slid in her tight sheathe. He held her down for a second, then pulled her off and let her get a few breaths. Then he said, "alright baby, let's get to that skull fuck you promised me" and began to roughly fuck his slick cock in and out of her tight throat while she gagged and choked around his fat cock...
...Castle very softly groaning as Tina knelt between his legs. It was a weekend and he was drinking beer and watching football while she serviced him. She had just brought him a fresh beer and then knelt back in her position, slurping him back into her love hole again. She was wearing a pink tube top and matching thong underwear. The tube top was obscenely stretched over her generous tits, and the thong framed her asscheeks and showed off the pink triangle tattoo on her asscheek. Several minutes later, Castle gave no visible clue that he was cumming besides a gentle sigh as he used her mouth to relieve his balls. She kept gently sucking and swallowed his load, then kept mouthing his tender cock afterward. He said nothing, just kept watching the game and took another drink of beer. He took his phone out to check it, and a few second later Tina felt the piss start to flow into her mouth as he used her to relieve himself once again, but in a different manner. When he was done pissing, she continued to nurse on his cock, drawing out the last few drops of his piss. After several minutes, he said "here baby, throw this bottle in the recycling bin and grab me another beer. Then you can recycle some of the beer I've been drinking with your sweet dyke mouth..."
...Sometimes Castle would fuck her pussy gently and tenderly, and she would almost always end up crying from her inability to really feel it. Castle would say sweet things like, "don't cry baby" as he gently worked his fat cock in and out of her and kissed and sucked at her neck, ears, and lips. These sessions were the closest thing she had in years to normal sex, and she always ended up sobbing in frustration. Her peaking misery always drove Castle to his own peak, and she would sob as he finally worked up the speed and came in her...
...Piss became an almost constant part of their sex as the week went on. Castle stopped warning her during their first heavy piss session. After those first couple of warnings, he simply pissed in or on her when he felt the urge. Almost every time she sucked him he would start pissing at some point, and she looked him in the eyes and drank it or played with it, opening her mouth so the piss could spray into it and on her face. Other times, he started relieving himself while he was fucking her, and she would romantically lick his neck or gently chew his earlobe and throatily whisper how good it felt when his piss sprayed in her pussy. Very late in the week, she had a moment of clarity. They had just had gentle, loving sex that culminated with her crying and Castle grunting and cumming in her pussy, then he pulled out and she moved down to suck and lick him clean. He immediately started pissing and she thought, "of course he has to go, we've been at it for a while" and started drinking it down, then snapped out of it and remembered that drinking a man's piss is abnormal and incredibly degrading and that she hated it. She had gotten so used to being his toilet she had forgotten to hate it. Her tears flew freely again as Castle groaned and used her to relieve himself...
...Castle started calling the Monday she would cum "C-Day". The last week of humiliating sex had built the anticipation so much she thought she would have a panic attack. She worked her overnight shift at the diner on Sunday night, but when she got home the next morning Castle wasn't there. She was on the verge of tears when she heard his key in her lock, and Castle and a huge black man came in.
"Hey babe, this is Trey, he works for Lamont. I told him about you and he said he's never seen a girl cum with her asshole, so I invited him to fuck you."
She just stared at them, then Castle said, "don't worry baby, you're gonna love his cock."
Trey said to Castle, "What's up with the short hair? Do you like it like that? I prefer long hair myself."
He then pushed her gently to her knees, and she knelt there in her diner waitress dress as they fished out their cocks. Castle's cock was the largest Tina had fucked, although Lamont was about the same size as Castle. Trey's cock was about the same length, but was substantially fatter than either Castle or Lamont. She could barely wrap her hand around Castle, but she was nowhere close to getting her hand around Trey.
"As long as she keeps enough hair to hold onto, I don't care. I told you she's a dyke so she tends to keep it pretty short. You make a good point though, maybe Tina should be a bit more girly."
She lubed them up with the bottle they kept by the couch, then jacked Trey's huge cock while she buried Castle in her throat and pumped on and off it a few times. Then she slurped on Trey's cockhead a few times and tried to go deeper. When it hit her throat, she realized just how huge it was. She worked it a bit with the opening to her throat, but there was no chance of her swallowing it easily.
As she moved her mouth between the two men and got them ready to fuck her, they talked shop.
"How long have you been at Lamont's?"
"About three weeks. I came out to LA to shoot porn, but I was too big for most of the girls. I met Lamont at a party and he hired me. With the movies he makes, it doesn't matter if the girl likes it." Tina made a gentle glurk noise as she switched back to Castle and buried his cock in her throat.
"She sucks pretty good for a lezzie," Trey noted.
They both watched her fuck her throat on Castle for a second, then he said, "she's had a lot of practice. I think I've just about fucked the lez out of her. Her favorite thing in the world these days is a nice gentle buttfuck. Isn't it Tina?" She pulled her throat off Castle, swallowed and took a deep breath or two, then glumly answered, "You know it is." Then slid Trey into her mouth and started working his cock while she stroked Castle.
Castle chuckled and said, "You should have seen all the fucked up shit she did this week to earn today's buttfuck!"
Conversation paused as they watched the pretty dyke work their cocks with her lips, tongue, and throat.
"Lamont showed me one of your vids earlier. Very hot stuff. I loved the scene with that teenage blonde."
"That shit was crazy. Lamont picked her up from the bus station that morning. She came to LA to become a star, and Lamont is going to make her one, though I'm pretty sure getting fucked on camera wasn't what she had in mind. She was tiny, maybe five feet tall and weighed almost nothing. She wasn't cherry, but her pussy was so tight it was almost painful for me!" Tina moved back to Trey and started slurping on his huge balls while stroking the head of each man's cock. Trey's description of the tiny blonde teen triggered Tina's lesbian nature and she got a bit turned on as she listened and tongued the cock and balls that had violated the defenseless teen.
Castle laughed, "it certainly was painful for her! She was bleeding by the time you got it in. I love it when women cry. Her sobbing was super hot."
"It was worse than the film showed. Toward the end of the scene, her pussy tore at the back toward her asshole like when bitches give birth. I loved it, all of a sudden she got very wet and loose, but it turned out she tore and the lubrication was blood. After she got so loose, I finally got to pound her a bit until I got my nut, but when I pulled out to come on her face, there was so much blood Lamont was worried it would kill the scene for some dudes." He paused as Tina pushed her head against his cock and tried to force it in her throat.
"Ow, baby, don't get too rough!" Tina pulled back and started roughly nursing the head of his cock and he said, "Ooooh, girl that is much better. You keep doing that and I'll feed you some of my sweet milk."
Trey continued, "anyway, Lamont had me clean all the blood off my cock, and then I jerked off on her face. Lamont checked her pussy out and decided the tear wasn't bad enough for stiches and her pussy needed to get bigger anyway. Lamont put her on blowjobs only for a couple of days until the bleeding stopped, then he popped her ass cherry and pimped her out ass and mouth only. It actually took a couple of weeks for her to heal, and Lamont later joked about it and said he should have gotten her stitched up, because her pussy is so loose now dudes complain about it! I haven't fucked her asshole yet, so I think it's still pretty tight." They both chuckled at the damage Trey's huge cock did to the girl as Tina slobbered all over the enormous black cock that had torn the girl apart.
Trey's large hands took control of Tina's head and increased the pace, using her mouth as a fleshlight to jerk himself off. He finally grunted in pleasure and filled her mouth with a large load of sticky white ball juice. She swallowed it down and sucked the last few drops from his cock.
No one told her to stop, so she kept gently sucking, but Trey said "hold on, baby" and she paused with the head of his cock in her mouth. He closed his eyes, and she realized what was going to happen just a split second before piss started spraying from his cock. Castle had thoroughly broken her over the last week when it came to drinking piss, so it didn't even occur to her to spit it out. He softly groaned in pleasure as she drank his waste, using her thumb on the underside of his cock to stop the flow so she could swallow and keep up as he emptied his bladder into her mouth.
Tina turned red with humiliation as Trey said to Castle, "You were right, this bitch is filthy!"
Castle simply relied, "She loves it. She was a prim and proper lipstick lesbian when I met her, but her true nature has come out of the last couple of years." As Tina swallowed down the last of Trey's piss, she wondered if Castle was right and this was her true nature.
After Trey had finished pissing, he didn't give her any direction so she kept sucking until he started to get hard again and in a few minutes he was rock hard again.
Once Trey was ready again, they paused to shuck their clothes, though Tina kept on the pink Y-back thong she wore to work because she knew Castle liked how the tiny panties framed her shapely ass.
They moved to her bedroom and Castle laid back and motioned for her to mount him in cowgirl position, she lubed him up, pulled her tiny thong to the side, and slowly worked him into her hungry asshole. Since she hadn't been fucked in her main hole for over a week, her ass had tightened back up and she was surprised how much it hurt as she slid down his cock. She paused just for a second and then started rocking her hips, feeling the pain quickly blend with pleasure as his fat cock stroked the pleasure centers in her asshole. Meanwhile, Trey stood on the bed and fed his cock back into her mouth.
Castle let her set the pace but tried to lengthen the stroke just a bit to make it better for her. He even gently stimulated her nipples and used his hands to gently rub her fat tits. He sincerely wanted her rare orgasms to be as good as he could make them, because then he could push her to even more fucked up and humiliating behavior before he let her cum the next time.
She quickly became lost in her own world of pleasure as she rode Castle and absent-mindedly nursed on the huge black cock in her mouth.
After maybe ten minutes, she was groaning in pleasure and building up toward the orgasm she had done such terrible things to earn. When Castle thought she was close, he said to Trey, "alright, let's do this" and Trey pulled out of her mouth. He grabbed the lube off the bedside table and lubed his huge cock while Castle lifted Tina enough to slide out of her now gaping asshole. She groaned in frustration when he slid into her pussy instead, but then he pulled her torso down so she was laying on his chest. She was close enough to her anal orgasm that she had a bit of a difficult time understanding what was happening until she felt Trey pull her thong further to the side and then she felt the blunt head of his enormous cock press against her fuckhole.
She made a loud grunting, "Huh!" noise as Trey popped the head of his cock in her asshole. With Castle's fat cock in her pussy, her asshole felt overstuffed and the pain pulled her back from the orgasm. But Tina had long ago begun to find some pleasure in the humiliations Castle drove her to, and having Castle in her almost numb pussy while a giant cocked stranger was gently but painfully pushing into her guts kept her right on the edge of pain and pleasure, and by the time the huge black cock was all the way in her ass, Tina had essentially collapsed on Castle. She was covered in sweat and seemed about to pass out. Castle motioned for Trey to pause, and they let her rest with their cocks inside her. She felt like her insides had shifted to accommodate the huge invaders, and the pain in her extremely stretched asshole mixed with the intense pleasure and humiliation to render her almost senseless.
Finally, Castle started to slowly and gently pump her pussy, and Trey followed suit. Soon they had a steady matched rhythm going where both cocks were slowly pumping in and out at the same time. Tina felt like she was hollowed out when their cocks pulled back, then felt like she might explode when they pushed all the way back inside. Her numb pussy provided very little direct stimulation to her, but the pressure of Castle's cock against the giant cock in her asshole was the most intense sensation Tina had ever felt. A few minutes after the double penetration started, Tina passionately kissed Castle on his face then whispered in his ear, "thank you!" as she shuddered into a mind-blowing orgasm.
Trey simply muttered, "goddamn..." as she twitched and milked his fat cock with her tight white asshole. They let her catch her breath for a few seconds, then started in again where they left off, sliding their huge cocks in and out of her body. She came again a few minutes later, but this time Castle didn't stop, so Trey kept going. It seemed like she kept coming for the next several minutes or so as they continued fucking her shaking body.
Finally she just collapsed in a sweaty mess on Castle, and they stopped. Every few seconds they stroked a tiny bit to keep their cocks hard, but they let her catch her breath.
Then they started again.
***
A while later, Castle was ready for a break and climbed out from underneath her. Tina seemed almost unresponsive. Before tonight, she had cum twice in the last two years or so. She had cum so many times tonight there was no way to keep track.
Castle asked Trey, "Beer?" as he walked out.
Trey said, "yeah, man" as he started roughly fucking Tina's asshole. Since Castle had pulled out of her pussy, her artificial tightness was gone and the damage Trey's huge cock had down was apparent. Her hole hung slack and open, and she lay there with her face on the bed drooling and vacant eyed as Trey grabbed her hips and started to roughly pound her ruined asshole.
Castle grabbed the beers and popped caps off while listening to the slapping sounds coming from the bedroom. He smiled to himself thinking about how blown out her asshole must be. He took the beer back in and handed it to Trey, who paused with his cock several inches in Tina's guts and took a big drink. After another big drink Castle took the beer back and set it on the table while Trey resumed his demolition of Tina's asshole.
Castle sat by Tina's face and used her hair to guide her mouth to his cock. She was semi-responsive as began to gently mouth the head of his cock. After several minutes of jacking off with her loose asshole, Trey pulled her back onto himself and blew his load deep in her intestines. He pulled out with a pop noise and wiped his sweaty brow as he moved to get his beer.
Castle set his beer down, moved behind her, and took in the sight of his little lesbian's ruined asshole. She'd spent the better part of an hour with a cock larger than a soda can in her asshole, and much of that time Castle's slightly smaller cock was in her pussy. The result was that as she knelt there on her knees, her pussy was stretched and distended and Castle guessed it would never be the same tight pussy it had been a week ago. He asshole, though, was hanging completely open. She had a gape about the size of a 50 cent piece, and the skin around her gape was red, raw, and slightly torn in a few places. Castle lubed himself up and stroked his rock hard cock staring at the damage Trey had done. Finally he slid into her asshole with a sigh and realized that her hole was so loose he could just barely feel it. He slapped her ass and started to pound into her blown out hole while thinking about his pretty lesbian and how far he had taken her.
It didn't take him long, and right as he was about to cum he felt Trey's cum start to leak out around his cock. He pulled out and shot a huge cumload into her gaping hole. He used his cock to push their cum back into her. She collapsed on her side on the bed, and Castle grabbed his beer to take as sip as he watched their cum drool from her destroyed fuckhole.
After he caught his breath, he and Trey gently helped her up and into the bathroom. He helped her into the tub, then had her kneel. As she knelt there sweaty and broken with cum drooling out of her damaged fuckhole, they sipped on their beers as they pissed on her. When they were done, she lay on her side in the tub stinking of piss with cum still running out of her.
She heard them talking in the other room but couldn't concentrate on what they were saying. Finally she heard the front door close and she willed herself to get up. Before she could get out the tub, Trey walked back in, with his huge cock soft but rapidly hardening.
"Turn that water on, baby. Castle said he's leaving town and I could stay for a few days. So let's wash your dirty ass and get back to some nasty fucking."
Tina sighed and paused for a beat, and Trey thought she looked utterly exhausted. He half expected her to resist, but then she leaned over and turned the water on. With a big smile, Trey watched the sexy middle aged woman get the shower going and rinse their piss off body. He loved her slender, fit body and big tits. He noticed the pink triangle tattoo on her hip as he grabbed the lube off the counter and stroked his cock back to full hardness.
When he was nice and hard, he climbed in the shower, closed the curtain, then turned her to face the wall. She made a gentle groaning noise as he slid his huge cock back into her loose asshole, then he said, "show me what you can do baby". He took a drink of his beer as the exhausted waitress started pumping her hips and stroking the stranger's huge cock with her raw and torn open hole.
***
Mr. Dobson took his wife on a spur of the moment vacation to Mexico a week after Castle showed him the photos. She liked Mexico so much, she decided to stay for a while. He made sure it was in a remote area and told her to tell her friends how bad the cell phone coverage was.
***
Castle and Diego retrieved Susan from the Dobson's rented villa on the beach near Tijuana. Her husband had drugged her and was in the process of raping her asshole when they arrived.
He acknowledged the other men's presence with a curt nod, then said, "you like that, you bitch? Since you're a cheating whore I figure you've already given your asshole to your boyfriend, so I might as well fuck it."
Castle and Diego had a glass of very expensive scotch in the kitchen while listening to Dobson finish in his wife's asshole. When he was done, he said, "you like Mexican cock? Well, I'm going to give you all the Mexican cock you want, baby."
When he was done, she lay drugged and draped over the couch drooling cum from her asshole as her husband gave Diego her phone and provided final instructions.
The deal was she would spend the next three months as a cut rate whore at Diego's place, then they'd return her to her husband. No sexual act was forbidden. Since she was a lovely blond California trophy wife, Diego and Castle planned to make a lot of money from her muscular little ass. On top of that, her husband was paying well, so this was going to be win-win. Diego would make sure she responded to texts from her friends, and he'd maintain the illusion that she was on an extended vacation rather than being whored out.
Later that night, Castle concluded there was no way her big dicked Latin lover was fucking her asshole. Even after her husband's earlier assrape, she was still painfully tight as Castle slowly but firmly slid into her. Castle loved the sensation of lubing up and sliding into a hole way too tight for his fat cock. Pussies were very nice, but they tore open too easily and the tightness was lost. If he moved slowly, Castle could get into a woman's asshole without tearing it (much) and her asshole would stay tighter much longer than her pussy. The resulting fuck was always incredibly intense. Truth be told, fucking a tight and mostly unused asshole was his favorite sex act. Susan was still drugged so didn't respond much, but she still felt wonderful wrapped around Castle's fat cock.
They were in the back room of Diego's place on the mattress used for breaking in new girls before they went on the market. Castle had put a couple of pillows under her belly to raise her ass up and was pumping in and out a leisurely pace when Diego came in with a young and lovely young Mexican whore. He sat on a chair and she knelt between his legs.
Over the young whore's slurping, Diego asked, "She is tight?"
Grunting a little, Castle said "very tight. I'm almost done here."
"No rush my friend, as you see I brought the lovely Maricia, who is still new and needs all the practice she can get." He gently smoothed her hair as he said it, and she kept slurping on his cock.
Castle took hold of Susan's firm hips and built speed, enjoying her tight anal sheath and her muscular ass. He grabbed a handful of blonde hair and yanked her head back as he picked up speed, finally reaching a point where he was laying on her back, brutally pounding her asshole while yanking her hair and beating her ass with his free hand. He came what felt like a huge load in her clasping asshole and lay panting on her back. He could feel her heartbeat through her asshole that was so tightly wrapped around his fat cock.
Castle thought for a moment about the beautiful woman currently wrapped around his cock. He had fucked so many women he had long ago lost count, but Susan had to be one of the most sexy. Castle loved the fitness girl look, and as he lay there still deep in her guts, he thought that maybe he should get Tina working out and see if she could develop a similar body. As he caught his breath, he felt his softening cock slip out of Susan's asshole and got up. He heard Diego stand up, and with a smile they traded places. Diego slid into Susan's pussy as Maricia slurped down Castle's slightly shitty cock and started working to get him hard again.
Diego quickly got a good rhythm going while Maricia finished cleaning Castle's cock and started sucking it in earnest. He felt himself hardening and realized it was going to be a long night.
***
Castle left the next day in the early afternoon. He and Diego had fucked Susan until they were exhausted, then took viagra and tried to fuck her again. Maricia fluffed them to get them hard again, and Diego managed to cum again, but Castle fucked her for a while until he realized he wouldn't come again and just passed out. Overall, it was a great night.
When he woke up, Susan was gone. During a very late breakfast, Diego explained that he had slapped Susan awake and put her to work that morning. Diego said that even though her face wasn't perfect, her body would make her a great earner. She had already fucked half a dozen customers before Castle woke up.
Castle just said, "Use her hard. Might as well give Stephen his money's worth and make some change while you're at it."
***
A couple weeks later, Castle was in TJ on a case looking for a lost daughter and stopped by Diego's. They chatted a bit and then Diego sent Susan over. The former trophy wife was dressed in only a tiny thong and slurped down his cock in the middle of the bar while they watched a stage show consisting of two pretty Mexican gals trying to fuck back against a huge double ended dildo in each other's assholes. Diego had pierced her nipples after she arrived, and the thick hoops running thru them shook prettily as she sucked him off. Finally, the girls onstage were grunting and pushing back on the now invisible dildo that was lodged several inches in their colons. Castle had a very satisfying cum in Susan's now talented mouth watching the pair on stage grimace in pain and make weird noises as the huge dildo filled their guts. Susan swallowed his load without hesitation.
***
Maybe a month after she was taken, Castle stopped by Diego's but didn't see Susan. A Mexican soccer team was passing through and they were immediately interested in Susan's muscular physique, so she was currently entertaining them, as she had been for several hours.
Diego said, "you should see her, my friend, she is a mess. But they continue..." with a shrug.
***
Castle very much enjoyed the new Susan. Being a deeply underpriced whore in a busy Mexican brothel meant her workouts now lasted 16-18 hours a day. She was very fit when she started whoring, but several weeks of emptying men's balls all day had changed her physique from "fitness model" to "hardcore athlete". She had no visible fat before, but now her muscles were sharply cut beneath her formerly flawless skin that was now marked but multiple bruises, bitemarks, and scratches.
Her asshole had lost its tightness, but she made up for it with enthusiasm and sheer strength. Many, many fucks ago she had learned that enthusiasm made men cum, so she used her muscular legs and hips to rut against Castle's cock like her life depended on it. They were in the back office again, but this time she was facing the wall and pushing her ass back to fuck against Castle. She was almost rough in the way she aggressively fucked back at him, and he came much faster than he wanted to in the muscle-girl's clenching asshole. When she realized he had cum, she spun around to suck down the remains of his ball juice, and after a few minutes in her skilled mouth he was hard again.
He took a handful of her hair and lifted her to standing, then looked her in the eyes and simply said, "do that again." She proudly smiled and turned to face the wall, and he plugged back into her asshole. She fucked him even more roughly the second time, her muscular ass clenching and milking his cock as she pounded back against him.
***
The next time Castle saw her, she was clearly being used up. Fucking all day long eventually wears a whore out, and Diego kept her price very competitive to be sure she got more than her fair share of cock. She had new wrinkles, and she had a tiredness in her eyes Castle had not seen in her before.
As she sucked Castle into her mouth and started trying to suck his balls through his cock, Diego explained that she had been very busy for the last couple of weeks. A surge in business and a lack of top tier American girls meant she was working almost 24 hours a day for more than two weeks. The wear and tear was catching up with her, Diego explained as he maneuvered behind her and slipped his cock into her well used cunt.
Later, after they'd filled her with cum from both ends, Castle told Diego, "her three months is almost up, there's no need to ease up on her."
***
Three weeks later, Mr Dobson picked his wife up from Diego's. She was a changed woman. The fight had been fucked out of her, and she looked like a soiled beauty. Her friends might notice a slight change where whoring had aged her a bit, but it was minor.
However, after only one day at home, Dobson called Castle and simply said, "she needs to go back."
It's not that Susan was disobedient, it's that her husband expected her to be utterly broken.
Castle picked her up the next day. The husband wanted her destroyed and agreed to allow some skin damage, but no damage to her face. He also had some very specific requests.
***
So, Susan went back to being a cheap whore, but this time Diego rented her to the roughest customers. If someone wanted a woman to abuse, Susan got the nod. A couple of weeks after she returned, Castle saw her and she had two black eyes as well as dark bruises all over her muscular and thong clad ass.
Two weeks later as she roughly rode his cock with her loose cunt, Castle noticed cigarette burns on her small tits and muscular ass. He even noticed a few on her pussy lips.
***
The next time Castle saw Diego, Susan was on stage performing. They chatted while the show progressed, first with Susan receiving a thorough fucking from a huge-cocked Latin man, then with her getting fucked by his Great Dane. When the dog's huge knot locked into her pussy, Castle thought he could see the desperation in Susan's face, which made it much easier to feed the pretty Latina bargirl the load she was trying to suck out of him.
Diego said, "the best part is when she cums on the dogcock. One dog in particular, a large Mastiff mix named Diablo seems to fuck all the resistance out of her. As he rides her and breaks her down, you can see it in her face as the humiliation turns to pleasure. My friend, I swear that the humiliation is worse every time because she knows what Diablo will do to her. She loves it and hates it so much."
Castle stayed an extra night to see it, and afterward told Diego he was right and that Diego really needed to film Susan's performances with Diablo.

Finally, Diego thought Susan was used up. It had been about seven months, and he had made sure she was his top earner almost all of those months. Diego sent her to the surgeon they used for the special cases.
***
When Castle came to pick her up, Susan looked like a different woman. Stephen had specifically asked for a series of changes, and the Mexican doc had made every single one.
Before the surgeon, she was a beautiful, very trim and muscular trophy wife, now she was a trashy and very trim bimbo. Her tits had been filled with very impressive implants, which Castle learned were "expanders" that her husband could inflate at will. As they were, the skin on her tits was so taut Castle didn't think they could expand right now without popping.
Her face had been reworked. Her oversized nose was gone, replaced by a cute little button too small to ever be thought to be natural. Her eyes had been lifted just a touch and her lips had been inflated just a bit.
The first thing Castle did is take her for a test run.
"I hear you've learned a new trick."
She just looked at him with her lovely new face, but she was clearly psychologically damaged from the involuntary changes made to her body.
"Why don't you pull out your teeth and show me what you can do."
She sat there looking a bit shocked as he fished his cock out, then his cock got hard as iron at the humiliation in her face as she pulled her false teeth out of her mouth and set them on the seat, then leaned over and swallowed him down.
Her gums were just incredible, and after having spent over half a year sucking off strangers all day long her mouth skills were remarkable. Castle closed his eyes, leaned back, and daydreamed about how to manipulate Tina into having her teeth pulled while Susan sucked and roughly gummed him until he forced her head down onto his cock and shot a large load of cum into her stomach.
Stephen Dobson's fitness model wife had been transformed into a very obedient, fake looking, big titted fuck toy, and Castle was sure Dobson would be pleased. Castle took her to his apartment in TJ for a few days before he returned her to her owner.
He performed every filthy act that occurred to him on her, and she took it all without hesitation.

Mr. Dobson was delighted. They were in his home office. He was behind his desk and Castle was sitting in a very comfortable chair on the other side of the large and antique oak desk. Underneath the desk, Susan was working very hard to prove to her husband why she deserved to come home. Her dentures were sitting on the desk, and the sucking and slurping sounds she made echoed around the room. She was wearing a skin tight red dress that clung to her new curves like obscene shrink wrap.
"My god, her mouth has gotten much better" Dobson looked at Castle with a bit of surprise in his face.
"She's had a lot of practice, and pulling her dentures make her mouth a very nice place to stick your cock. That was a good call on your part."
"Her face turned out lovely. I always hated her big nose. Now it's a pretty little button nose, and then her tits..." he closed his eyes and paused in pleasure while slurping noises filled the room, "they are so fat. They expand?"
"Just like you asked, there's a valve where you can pump them up more as her skin stretches. They can inflate to three times their current size."
"Uuuum, perfect." Dobson was distracted by Susan's gumjob.
Castle thought about Susan's current tits. They were inflated as much as they could be, to the point of causing her pain as they stretched the skin of her rock hard softball sized fake tits. During her time with him over the last few days, Castle had very much enjoyed pinching, slapping, squeezing, and otherwise torturing her lovely fake tits. He knew her husband would get great satisfaction from pumping those balloons up over the years to come. By the time they were fully inflated, the girl would have taut, soccer ball sized milk bags hanging from her slim, muscular frame.
Dobson sat back and enjoyed his wife's skill, pleased with his decision to modify her mouth to make it a better fuckhole.
Uncomfortable, Castle said, "look, I can come back later..."
Over the slurping sounds of his wife Dobson said, "no need Mr. Castle" as he opened a drawer, pulled out a check, and handed it across the desk. "I added the extra amount for that special arrangement you made."
As Dobson paid Castle, the moment became very uncomfortable because he very obviously came in his wife's mouth.
"Ungh"
Castle took the check from his hand as Dobson closed his eyes and unloaded his balls in his wife's mouth.
After the moment passed, Dobson opened his eyes and said, "When will Diablo get here?"
His wife visibly stiffened and apparently stopped pleasing Dobson because he roughly slapped the side of her head and said, "no one told you to stop, whore!"
As she got back to work, he said, "I've been watching your videos baby, and I just loved watching Diablo make you cum. The humiliation in your face as you came so hard on his dog cock is the hottest thing I have ever seen. I did some soul searching after you cheated on me, and I know now that my cock just isn't enough for you. This way you'll have all the cock you can handle, and, while I know it's hard for you to admit, we both know how hard you cum when your doggie boyfriend fucks you." They could hear her gently sobbing as she kept gumming his now hard cock.
Castle waited a beat and then said, "Diego's men will bring Diablo tomorrow. The trainer is also coming to show you how to care for and control Diablo, and men are coming to install the cameras."
"Control him? Ha, I've had a special cage built that's big enough for both of them. Diablo is going to get as much bitch pussy as he wants, and my lovely Susan will be having those humiliating orgasms whenever Diablo decides to give her one." He looked down at Susan and said, "Baby, I worked out a deal with Diego to record you and Diablo, and Diego will sell the vids. My whore is gonna help pay back all the money I invested on her aren't you?" She just kept sucking and gumming him as tears rolled down her face.
Castle turned to leave and heard Dobson say, "I'm gonna sit back and let you jerk off my cock with your muscular ass. I know your hole isn't tight anymore, but Castle told me you can clench the ass muscles you've built and it feels incredible." As Castle walked away, he heard Dobson groan in pleasure and heard the sound of slapping hips as Susan roughly fucked her asshole on her husband's cock like a human fleshlight.
