As Frisk downed the rest of the cider the spider-girl infront of him smirked and held out one of her hands. “That’ll be 1900 gold deary~” She says, Frisk digs into his pocket only having about 150G on him. “Oh, not enough? Hmm no matter, I suppose I could take other forms of payment~” Muffet slowly steps out from behind the booth, looking over Frisk. “I could use some help with some of my other shops set up around the Underground.” She explains resting one of her hands on Frisk’s shoulder. “If you help me for a bit we can forget about this, what do you say?” Frisk stares up at her blankly before nodding, the spider chuckles and clasps two of her hands together happily. “Oh that’s wonderful deary, come with me and we can get you started.”


        It didn’t take long for the two of them to arrive at Muffet’s parlor as they take a seat in two chairs covered in webs. “Now then all I ask is that you stay here for a few days and help out, think you can do that?~” She asks placing two of her hands on the web-table infront of them making her breasts push out a bit. Frisk nods again not seemingly phased by Muffet’s “persuasion” “Great now how about I show you to your room and where you will be staying.” She explains sliding out of the chair and heading deeper into her parlor, with Frisk following behind.


        After a quick tour around Muffet and Frisk end back up where they started. “Well that’s all for now, how about I get you something to drink before heading off to sleep. On the house for my temporary employee.” The spider laughs a bit as she strides to the fridge (Which was suspended by more webs) and takes out a container filled with what looked like Spider cider, though this kind was much more thick and creamy looking. After pouring him a glass the spider sets the glass on the table next to Frisk. Who after thinking it over for a bit starts to drink from the glass. The taste was much stronger than regular cider and had a bit of an aftertaste to it.


        Chatting for a little longer Frisk soon heads up to his room and gets ready to go to sleep. As he slipped into bed her would feel a slight tingle go through his body, thinking nothing of it he quickly drifts off to sleep. The following morning after eating a nice hefty breakfast they head out, setting up shop nearby Muffet noticed Frisk more curvy, and thickly hipped frame. Smirking lightly the spider goes to grope the boy’s ass but stops herself figuring it wasn’t the right time yet. As they worked throughout the day Frisk didn’t see to notice his pants getting tighter as his ass and balls swelled with size, creating a nice bulge around the front of his pants. 


After a bit of time Frisk finds himself getting a little shifty, his pants for some reason were very uncomfortable, and the thick bulge in the front of his pant was throbbing every few minutes. Muffet looks over murring lightly as she spots the pulsing bulge, laughing a bit she says “Ahuhuhu, having a little problem there aren’t you dearie?” She reaches down patting the bulge, making Frisk shiver and blush in pleasure. Slowly she starts to undo the boy’s pants and helping him out of it. “There we go that should be better~” As his pants come off all the ass fat trapped inside just seems to pour out, giving his rump a little bit of a jiggle. This is soon followed by his now larger cock. What appeared to be extra flesh seemed to be spreading down his shaft, the only difference was this skin was a light purplish blue, similar to Muffet’s.


His balls had also gotten quite larger hanging between his knees as they sagging and pulsed with large amounts of seed. “Ahuhu hm I think we have enough for today, how about we head home now and I can help you out with your little, problem?” She asks tapping the tip of his throbbing cock. Frisk lets out a small gasp and shaky nod as they start to walk back, leaving the boy’s pants behind. Arriving back at the parlor and after another glass of thick, delicious cider, Muffet stands over Frisk wearing nothing on her perfect body. Lightly she grasps the shaft of her cock with two of her hands while using another two to fondle her balls a bit. “Now then how about we help with that little problem of yours~.” She coos walking a little closer. Leaning down she pressed the tip of his prick against her own before sliding into his shaft with a wet *SCHLOP* noise. Laughing a bit she starts to pump in and out of his sensitive cock, jizz pouring out either side of it as Muffet gives it a nice pounding. With each thrust Muffet pours more of her own Spider Seed into his balls, watching them swell more and more until they touch the ground.


With one last pump she pulls back out with an equally wet noise a long strand of cum connecting their tips before breaking off. Frisk’s cock was now pouring a hefty amount of seed from the tip as his balls rubbed and dragged across the cold webby ground. Which only made him cum more. “Fufu there we go, how do you feel?” She asks slowly sliding her jizz stained panties back up, which somehow managed to cover up her “assets.” Due to the pounding even more thick, smelly purple flesh had grown onto Frisk’s shaft now creating a nice hood around the tip of his dick. His balls were also a nice healthy purple and had quite a few wrinkles and creases in the musky flesh. 


After sending Frisk off to bed Muffet waits a little while before heading upstairs with what seemed to be a milking machine. Pulling the covers off of the young human boy she licked her lips looking at the big dick. “Now this is what it was all building up to~” She whispers to herself as she straps the milking tube around his tip. Slowly she started to extract thick, “cider” from his cock, watching it fill into many of the bottles below. She had heard rumors of how a changing human could make some of the best organic cider, and now she had one of her very own.


The next morning as Frisk slide out of bed he felt himself being yanked to the ground, by the weight of his sagging balls. After dusting himself off and walking out to the main parlor area he noticed Muffet sitting at the table using one of her hands to drink tea while using to others to read what appeared to be a magazine. “Mornin.” He says with a small wave sitting down across the spider.


“Ah morning dear, sleep well?” She asks setting down the magazine which now was seen to be a rather obscene porno mag. “I have a bit of a special plan for us today. I am going to put you through a little bit of training, you know just to get you into the job~”  


“Sounds good.” Frisk nod giving a thumbs up. After eating breakfast the two of them head deeper into the house. Muffet leads him back into a room hidden in the very back of the parlor. Turning on the lights revealed a room with just a stage and another door laying on the other side of the room. In the center was a large stage with a large, thick pole in the middle of it.


        “I decided maybe it would be best to try out something new to attract some traffic, and since you’ll be working with me for awhile I thought you would be best.” She says stepping onto the stage. “Though as of now it might be best for me to show you and then you can try a bit later?” Frisk nods again as he watches Muffet climb onto the stage using her two upper arms to pull herself up onto the pole. Slowly she started to use her other arms to strip off her clothing showing off her thick cock and ass.


        She wrapped her body around the pole before sliding down coating one side in the pre dripping from the tip of her dick. It didn’t take long for her to work on a sweat, heavy between her breasts, armpits, balls and ass. The stink of her body quickly filled the room. The air grew stuffy and heavy with musk as Frisk watched unaware of his body continuing to change. His cock grew larger now almost as big as him The purple skin was also starting to creep up his body, specifically around his plumping ass and thickening asshole forcing his fat cheeks apart.


        Soon Muffet stops climbing down and patting as she walks over to Frisk. With a smirk she plops her balls down in the boy’s lap giving him a slight wink as the spider’s swampy ball stink fills his nose. The boy blushes deeply, something in the back of his mind was telling him this was wrong but at the same time it was very faint. “Ready for you turn?~” She asks seeing Frisk lean down taking a deep sniff of her sac as he gets back up.


        “Ahu yeah let’s go~” He replies his dialect sounding slightly similar to Muffet’s Slowly he climbed onto the stage looking back, causing his cock and balls to swing, he gives a small wink and smirk to Muffet who was sitting back in her seat, drenching it with sweat as she smiles. Frisk climbs onto the pole rubbing his cock against the still warm metal, wet from Muffet’s pre. He starts to spin and dance on it almost like a pro. His balls and cock throbbed with each movement pre spurting out from his cock landing all around him.


        “Mmm that’s a good.” Muffet says as she plays with her sweaty balls and thick shaft. Watching the young boy on the stage makes her murr in pleasure stroking her cock as he leans back. The added weight from his Junk put a little more weight into Frisk’s dancing already making him sweat heavily. As he finally finished his shirt was soaked and he smelt pretty bad. A rather large pair of breasts had also grown on his body which was nice and outlined by his tight shirt.


        Muffet leaned in close breathing in the boy’s musky stench. “Mmm good work out there dear~” She says pulling him into an embrace, pressing their cocks together as Muffet’s foreskin covered cock tip pressing again Frisk’s nose drooling pre onto his face. Muffet chuckles a bit still stroking her cock, it doesn’t take long for her to climax, covering the boy’s face in her thick musky seed. “Now how about we get something to eat and head back, it’s been a long day of practice.” 


        “Yes, that sounds lovely darling~” Frisk replies with a bit of a laugh using his sleeve to wipe the jizz off of his face. The two of them head back out a cold breeze brushing across their musky bodies. Their thick long ocks swinging in the air as they head back to the dining area.


        “So what can I get for you dear?~” Muffet asks smiling lightly sauntering over to the fridge, her thick asshole shining and dripping with sweat. Frisk licks his lips as he stares at the massive donut, his thick throbbing dick pumping against the table.


        “Hmm whatever works~ maybe some spider and some pastries?” Frisk asks squirming a bit in his seat as the spider ends over slightly. Showing off her assets even more. Thick heavy balls dangled between her legs and her fat used “spider donut” puffed out lewdly. As Frisk stares something in the back of the boy’s mind told him something about this was wrong. He was meant to be doing something else, but what was it? He didn’t even notice Muffet walk back over setting a plate of spider donuts and a glass of cider in front of him


        “Ahuhu a little distracted are we?” She asks, as Frisk looks up he could see the underside her swampy, musky pits. Loads of sweat just dripping from them making her skin darker in comparison. “Maybe you’d like a closer look?” She asks walking over to Frisk before pulling him against her body, pressing his nose deeply into her armpits. Instantly the stench of musk fills his senses making him tense up and moan lightly. His body start to plump up more as well, cock throbbing and spurting against Muffet’s chest.


        “I-it smells so… nice…” He mummers  blushing deeply as he humps against her body, his cock slipping between her two plump sweaty breasts. Their sweaty balls slapping wetly against each other as muffet holds the boy there. After a bit Muffet pulls the dazed human out from under her pits setting him back in the chair. 


        “How was that?~” Muffet asks curiously chuckling lightly as Firsk gave a weak and dazed thumbs up, his head and hair drenched in sweat. “Good now go ahead and eat up, tomorrow is a big day.” Frisk gives a small nod as he starts to eat, stuffing his face with the pastries and washing them down with a glass of warm cider. 


        “Mmm thank you again dear for letting me stay here for a bit~” Frisk says voice sounding a little more feminine.


        “Ahu of course, it was nothing dearie~” Muffet replies. “After all it’s always nice to have a new worker here, especially one as talented as you~” The spider chuckles and smiles patting Frisk on the head. “Now how about we head on off for now and get some sleep~” Muffet starts walking towards the stairs shaking her massive rump with each step, making sure Frisk was not only following but watching her hypnotizing rump.


It was only as they got to the top of the stairs that Muffet stops, with a chuckle she stretches and bend over. Slowly her massive pucker yawns open as it rips a loud, hot *BRAAAAPPPPT* the warm gas rushes over Frisk making him shudder and moan as he breathed it in. “Ahu sorry dear was feeling a little backed up~” She explains giving her thick ass a small slap before continuing to walk. Frisk stays behind for a few moments, rubbing his thick musky cock as he breathed in the stink lingering in the air. He soon arrived upstairs only to find Muffet laying on the bed, stroking her massive cock while staring Frisk down with her many eyes. “Fufu come and join me~ I have a special little reward for you after this long day of work~” She coos, Frisk seems to hesitate for a moment pausing before he starts to walk over.


“What did you have in mind?” He asks with a bit of a stutter in his voice. A voice in his mind was telling him all of this was wrong, and he needed to get out of there. But no matter how much he struggled his body disobeyed him and kept walking towards Muffet. The spider woman chuckles standing up, and reaching forwards as she pulls Frisk closer.


“Oh you know nothing too big, just wanted to have some fun.” Slowly Muffet pressed his cock up against Frisk’s own prick. The tip slipping into Muffet’s saggy foreskin with a wet *SHHLOORP* The inside was warm and wet with old cum and musk as Muffet leans down pressing the young boy’s face between her large, musky tits. Frisk felt his cock surge as he was forced into the sweaty, smelly mound infront of him. “Ahu that’s right just go ahead and breathe in, let your mind succumb to me~” Once again something surges through Frisk’s mind as he starts to push against the Spider woman, though weekly.


“N-no this isn’t right..” He mutters his cock still pumping and pulsing out of his control. “I need to get out of here.” Suddenly Muffet reaches around with her two other hands giving his rump a nice firm squeeze while using two more of his hands to stroke and rub the poor boy’s throbbing prick.


“Oh what could you mean dear?~ Don’t you want to be a good worker? A good, slutty spider worker?~” She coos lovingly  continuing to grope and rub the boy’s body, even as it slowly starts to plump out and grow more. His shirt started to become more and more constrained tightening around his now thicker chest and taller body. 


“N-not like this..” He growls lightly his voice now almost completely identical to Muffet’s as he finally breaks free. However as he does the boy falls backwards onto the floor, grunting in pain though his fat ass absorbed most of the damage.  Slowly he pushes himself off the ground, purple covering his body as 4 small nubs appeared down his torso. “I won’t lose here.” He raises his arms, having left his weapons and armor in his now lost pants, even so he was filled with the determination to win and leave.


BATTLE START


“Ahuhu do you really think you can win dearie?~” She asks with a laugh as she slowly stripped off her clothing, her large breasts pouring from under the skirt as she stretched her arms green balls of musky stink poured from her pits flying down at Frisk’s SOUL. He manages to avoid them all, even though he was slowed by his fatter ass and much, much larger cock. 


“I may not be able to fight but I will find a way to win.” Frisk ACTs with a scowl. Muffet chuckles turning around as she bends over.  Her thick pucker causing Frisk to shudder, causing his defense and speed to lower. He tries to ACT again but something seems to stop him, as he can only gaze into the thick pucker which was slowly yawning open. “D-ang w-why can’t I move.” He says frozen in place, face now lowered right in front of the open flesh cave that was Muffet’s asshole.


“Ahu because you belong to me~ I just have to break that silly free will of yours~” She coos ripping a loud *FFFRRRAAAAPPPPPPTTTT* right onto Frisk. The thick gas pouring over his body and SOUL covering the box in a green mist, blocking his view.  As Frisk gain control of his body again he stumbles back cock drooling thick globs of pre onto the ground below him, leaving his cock nice and slick with the stuff as his pubic hair started to grow out growing into a nice, thick, and very musky bush around his crotch


“S-shoot what is happening?” He pants out, a heavy blush covering his face looking down he noticed that the small nubs had now grow into two new pairs of arms that had torn through his shirt shredding it to nothing, showing off his thick, purple body. 


“Oh we’re so close~ just a little bit more dearie~” Muffet says quickly rushing in, making sure Frisk had no time to ACT as she shoves her thick cock right up against the boy’s still pure SOUL. The red heart is quickly pulled into the hood of the spider’s cock. Frisk let out a groan as he felt the warm musk and old jizz cover his soul, causing him to pants and fall to his knees.


“N-not like this..” He says one more time as Muffet laughs giving her cock a hard thrust as she sprays a nice coat of jizz all over Frisk, something hard and dripping thumps against his chest, causing him to orgams as well. Moaning loudly he throws his head back, spraying the rest of his humanity onto the floor infront of him. After finishing he slumps his head down seeing his SOUL stained a bright white, dripping with the Spider’s cum. The SOUL no longer that of a human but just another monster. Infact it was now a SOUL identical to Muffet’s, and his body was soon to follow.


“Oh yes like this~ Muffet says collecting as much of Frisk’s “cider” as possible as the boy’s chest starts to push out. Large mounds of flesh grow from them as his nipples puff out a nice stream of what appeared to be cider dripping from them as he panted heavily. Muffet laughs again as he walks over, tying a large bow in the boy’s head. Looking up Frisk seemed a little dazed as he looked up with his 5 eyes “How do you feel my dear?” Muffet asks smiling a bit. Frisk chuckles a bit and smiles as well, showing off his new spider fangs.


“Ohh I feel absolutely amazing dearie~” Frisk replies smiling a bit. “Oh but I think I might need some new clothes to wear~” He says raising his top arms to stretch, middle arms to grope and squeeze his new breasts, and lower arms to stroke his massive cock, which now was nice and hooded like his fellow Spider. His underarms had now also grown a rather thick forest of hair under each and every arm. All of them nice and damp with sweat.


“Ah yes of course~ don’t worry we can get you some stuff, though for now how about we get some rest for work tomorrow~” Muffet replies patting her new Spider clone on the head. The next morning Frisk awoke nice and early, his balls and breasts painfully full as he climbed out of bed. Heading downstairs he sees Muffet with what appeared to be two milking machine. “Nice and full this morning?” The spider asks.


“Mmrrf very~ I might need some help dearie~” Frisk says, Muffet doesn’t reply as she pulls the machines over, one having just a singular massive pump and the other having two smaller pumps. She quickly hooks them up to Frisk’s cock and breasts and switches it on. Relief almost immediately rushes over him as a light cider flows from her breasts and a thicker more creamy cider, similar to the one he drank poured from his cock, both machines fills up rather quickly Frisk moans happily as they remove the pumps, his foreskin dripping with leftover cider that stuck to the inside of his hood.


“My my, you certainly produced quite a bit, I guess I was right to choose you~” Muffet says with a giggle giving Frisk’s ass a nice firm smack. “Now let’s get to work so you can’t put yesterday’s practice into work. But first, let’s get you some clothes.” The two of them share a laugh before heading off.


Frisk’s first true day of work was amazing, Muffet had set up a nice, thick pole next to the stand for Frisk to attract customers. They had sold a massive amount of cider that day, though of course there was at least one person that couldn’t pay. They happened to end up either under Frisk’s massive ass or in a headlock under his sweaty pits. Making a new mindless worker for them until they paid off their debt. It didn’t take long for news to spread about Muffet’s new partner. A shemale spider dressed in nothing but a puny purple thong and ridiculously short dress that left nothing to the imagination, and who smelled like she hadn’t washed once in her life. About Muffet’s new spider cider, which was incredibly addicting many monsters couldn’t get enough of it, even as they fell into debt, which by then they would have to work it off. Helping with the Spider’s ever expanding business.
