Summary:
Gobta had an unexpected transformation after eating Shion's cooking at Rimuru's fear for his life. Gobta, now a young hobgoblin with bountiful assets, found 'herself' in an situation in the hot spring.

.....

"Shion," a cold tone was heard from Rimuru as they observed Gobta's 'dead' body on the ground, foam leaking from his mouth. "From now on, before you present any food, make sure to have Benimaru taste it first!"

The young redhead master turned to Rimuru, panic and fear etched on his face as sweat trickled down his brow. 'That's too cruel, Rimuru-sama!' His thoughts were transmitted to Rimuru, who only shrugged and stuck out his tongue. 'Don't care. She's your problem now.'

"Uhm..." Shion muttered in surprise. She noticed smoke emanating from Gobta's body. "Rimuru-sama... something is happening?"

Rimuru looked at Gobta, confused. The young goblin was beginning to glow and morph. "What the hell is going on?"

<<Noticed. Physical reconstruction is occurring on the individual Gobta's body.>>

'Reconstruction? What does that mean?'

As they continued to observe, making no move to stop the event, Gobta's short frame began to grow taller by a few inches. His mohawk-style hair started to lengthen, filling his head with lustrous gray strands that reached past his shoulders. His belly shrank, only for his chest and buttocks to swell and fill out unnaturally.

"What the...?" Benimaru muttered, his expression contorting with disbelief as the transformation grew more surreal by the second. "Shion, what did you make?"

He couldn't help but exclaim. The purple-haired ogre had somehow managed to create a mysterious concoction that could alter the victim's body. Shion shook her head, her own worry mounting. She was just as confused about what she had made—and the fact that Rimuru was supposed to have eaten it.

Gobta's body continued to change as they spoke. His height increased until he was nearly as tall as Rimuru. His chest expanded in proportions that were unnatural for a 'male,' and his buttocks followed suit, growing to an extraordinary size that made even Shion's form look small in comparison.

The sheer size of his transformation was nothing short of shocking.

Gobta began to frown as his eyes fluttered open. His 'chest' felt heavy, and an itch ran across his neck and ears as he felt hair growing. He rubbed his eyes and looked at the others, who were staring at him in shock.

"Rimuru... sama?" His voice was now lighter than it had been before. Gone was the funny, almost mocking tone and accent he usually carried; instead, it was sweeter, more feminine.

....

It had been more than a few months since then.
The orc lord and the orc invasion had been taken care of. The city Rimuru had dreamt of building for them to live in had been steadily growing into fruition. The orcs, specifically the two thousand orcs residing in the city, were excellent at construction and had helped create the vast majority of the permanent structures in the city.
Life was beginning to feel more stable and safer for everyone in the forest.

"Rimuru-sama," a green-skinned young woman with excessive proportions called out to the slime. "I heard you might have found a lead on how to turn me back?"

Rimuru blushed as he saw the hobgoblin's 'assets' sway, quickly closing his eyes and cursing himself for knowing who they were attached to.
"G-Gobt— I mean, Nemuri, I just said that we need to recreate the exact recipe of Shion's 'food' and analyze it to make an 'antidote.'"

Nemuri, formerly the goblin Gobta, dropped her shoulders, sulking at his words. "I see... Sorry for the interruption." She turned and walked off, Rimuru's eyes trailing down to her behind and how tempting she looked from behind.

'No!' Rimuru cursed himself, slapping his face. 'That is Gobta, there is no way I am aroused by that idiot!'

After Gobta's... transformation into a girl, Rimuru and the others quickly attempted many things to return him too normal. However, with the incident occurring during the orc lord invasion, most of the attention and resources were focused on the battle.
Even after the battle was over, Rimuru had focused on relocating the surviving orcs and constructing the city. Even now, Gobta's issue was kept on the backburner until everything had settled down.

"It is weird, though, that he wants to be called Nemuri..." Rimuru muttered as Gobta eventually started telling people to call him Nemuri. It was as though, slowly but surely, he was beginning to accept his new form.

"Whatever, we'll resolve it when Great Sage can find a lead." Rimuru stretched and turned into his slime form, jumping toward the hot springs.

Rimuru found no one else had entered the hot springs. Seeing that, he moved toward the men's side. Normally, he would go to the female side, but with no one present, there was no point.

"Hahh..." He let out a satisfied sigh, though he couldn't feel the heat of the water. He was merely floating around in the water, surrounded by tiny miniature Rimurus, akin to rubber ducks.
"We sure have advanced in such a short time." He reminisced as he stared into the night sky.

Suddenly...

"Mh~"

Rimuru looked around as if he heard something, 'what was that?'

"Mhaa~!"

Rimuru jumped out of the hot spring in surprise, he began looking around with his slime body for the origin of the noise. Then with his magic sense, his body turned to the other side of the wall.

The wall was the only thing separating the men from the women side of the hot spring. He felt himself grew embarrassed and curious as he continued hearing the strange noises coming from the other side.

"It, it should be fine if I come over right?" He tries justifying, as he has already done several times barging into the women's side.

He slowly slithered his way to the other side of the wall. Sticking to the wall and moving quietly hiding his presence, normally he wouldn't be this cautious or careful about going but...

"Hahh~ right here~"

The sounds were getting clearer in his mind and his thoughts were getting weirder and weirder as images began appearing on his mind on what was happening.

As he finally reached the other side, the first thing he noticed was the massive green breast being caressed and pinched by its owner.

'Go-Nemuri?!' Rimuru (metaphorically) was wide-eyed from what he was seeing. The green hobgoblin was sitting in the edge of the hot spring 'her' hands on her massive breast playing with them.

"This is... mh~!" Nemuri let out a light moan as 'she' pinched 'her' nipple. "This isn't right... Ever since I change.. ah! I, I.. ahm~!"

Nemuri was having a crisis in 'her' mind. Formally Gobta who was known as a childish stupid goblin who has a bit of a perverted streak for woman was now playing with 'herself' as a woman.

"This... Rimuru-sama better find a cure quick." 'She' sighed as she let go of her breast. Staring at them for a long time, normally 'she' would be completely aroused by such massive bosoms but for the past months she has grown used to them.

"If this continues.." 'Her' hand trailed over 'her' breast to the waist and between 'her' legs. "I might not want to return to normal..."

Sighing to 'herself', she was about to jump to the water when she felt two hands coiled at 'her' stomach. The arms locking 'her' in place as a presence latched themself behind.

"Wh-who is there!" Nemuri blushed as 'she' turned her head. The sight of a silvery blue haired man can be seen, "Rimuru-sama? Wha, wait who are you?!"

The person behind 'her' was similar to Rimuru. Yet, it was someone much bigger and muscular than the master 'she' served. The same height as Benimaru, with a body rivaling even Rigur. The long hair was way passing his back and with a sly almost lustful glint in his eyes, 'she' felt 'her' legs tightened.

"It is me," The deep voice echoed in Nemuri's head. Before she could process the words, the hands on 'her; waist raised up to 'her' breast.

The large hands were nothing compared to the unnatural breast the green skinned woman had. The fingers began to sink into the flesh, not even able to cover the entire thing with his open palm.

"I have been seeing this for months now, but they really are big." He whispered in 'her' ear as he began massaging and playing with them.

The grasp he had of 'her' breast grew firmer as 'she' continued to hold 'her' moan, moving around slightly as if resisting his caresses.

Nemuri bit 'her' lips as the moans were beginning to grow louder as the pleasure began building up inside 'her'. 'Her' hands went up to his, one might thing that 'she' wants them to let 'her' go.

Instead, they only held his hands as if finding some place to grab onto as the pleasure was getting too much to bear. "Look at me~"

Hearing his deep demanding voice, 'she' couldn't help but follow and turned 'her' face. As soon as their eyes met, their glazed eyes getting closer until their lips touched.

Their eyes closed as their tongues danced around. One of his hands left 'her' boob and moved between her legs.

"Hm~!?" With a muffled yelp in their deep kiss, Nemuri felt a finger inserted inside of her hole. 'Her' insides were quivering, it has never felt anything other than its owner's hand entering such a place before.

The wetness and juice spilling out in his hand was a testament to 'her' desire leaking out to his palm.

Breaking from their kiss, Rimuru stared deeply into 'her' eyes. "Why don't you get down and let me feel those boobs."

Nemuri blushed at the bluntness of his words, 'she' nodded 'her' head and got down to the hot spring. Rimuru sat at the edge, where she was in previously, and 'her' upper body was just in the right spot to meet his lower one.

Nemuri stared at Rimuru's member standing tall. It was the first time 'she' has ever since Rimuru with any form of genitalia, granted most of the time he is in his slime form. Even then, the sheer size was almost as unnatural as 'her' body.

'She' gulped as 'she' slowly moved her breast and sandwiched his member. Surprisingly, even with her large assets, the head was still peeking out of 'her' cleavage.

'She' shuddered just imaging it impaling her insides. She can feel the form in between 'her' breasts.

Rimuru groaned lightly as the breast that has been seducing him for months has finally become his. The soft feeling of flesh squeezing at his member was heavenly. "Lubricate it."

Nemuri nodded, opening her mouth and letting saliva dripped down his member. As the saliva began to lubricate his member and 'her' breast, 'she' began to slowly move them.

Kneading them back and forth as she carefully massaged his member with the intention of pleasuring Rimuru, 'she' was glad to see him groaning with his eyes closed.

'She' felt pride seeing the expression 'her' master was making. 'She' deliberated for a second as she observed the member appear and disappear in 'her' cleavage.

Repositioning herself to show more of his shaft out of her breast, her wet long tongue began to trail on the exposed parts. Rimuru's eyes opened wide feeling the sudden wetness and trailing feeling.

Looking down at 'her,' Nemuri was staring right back at Rimuru. 'Her' eyes were asking if she was doing good. Suddenly, she took his entire member into her mouth.

"Shit..." Rimuru cursed as she closed his eyes again to enjoy the moment. Bobbing her head up and down, sometimes taking it out and making long licks and soft kisses on the tip.

"Where did you even..agh" Rimuru's hand unconsciously landed on her head, moving the long hairs that began to cover her face.

Taking out his member, Nemuri smiled almost teasingly. "I have been having... not so male thoughts about Rimuru-sama for a while now."

Rimuru felt his expression crack slightly as the young woman's smile felt so alluring and adorable he had to look away.

Nemuri took this as a sign to continue. Picking up speed, her bobbing head and the squelching sound of saliva and flesh were the only things he can hear and see.

"Fu-" Rimuru's hand on her head grasp a fistful of hair. He was close, and he wants it to be as good as it can be.

With his other hand moving to 'her' head as well, with both hands embedded on her head. 'Her' eyes looked up at him, with their eyes staring at each other's lustful gaze the paced increased in anticipation of what's to come.

Bucking his hips, he moved his hand in unison to thrust into 'her' throat. Surprised, Nemuri grabbed at his thigh as Rimuru began to use 'her' mouth as his plaything and 'her' head as handles to control his toy.

She can feel his member reaching the deepest part of 'her' throat. One can see Nemuri's throat slightly bulging every time Rimuru thrusted deep in 'her' mouth.

He could feel his orgasm rising, with it coming, he plunged his shaft deep into her throat that 'her' mouth took in every bit of his member. Rimuru made sure to held 'her' in place as ropes of his essence continue to paint 'her' stomach white.

Nemuri did not resist, in fact 'she' held onto his hips and began to suck making sure to take every single drop that came out of him.

Rimuru sighed, satisfied with playing with 'her' breast and mouth. With his hand still in 'her' head, he raised 'her' head off his member. Nemuri swallowed licking 'her' lips before opening her mouth to show Rimuru.

Rimuru felt his arousal double seeing such a scene before him. Two blue tendrils grew from his back, the two appendages grabbed a hold of Nemuri who took 'her' out of the water.

Laying her on the floor near the water, the two tendrils wrapped themselves onto her hands. Wriggling and coiling around 'her' arms.

"Ri-Rimuru-sama?" 'Her' tone was light and slightly worried. Rimuru moved himself in between her legs, with both hands on her knees, he spread her legs wide open.

Before him was a wet and puffy lower lip quivering whether in excitement or fear he did not care. Licking his lips, he dove down on 'her.'

"Wai- Ah~!" Nemuri closed 'her' eyes as 'she' felt Rimuru's tongue playing with her core.

Eagerly lapping into 'her' lower lips, Nemuri couldn't help but squeeze her thighs together due to the unknown experience it was having.

"Rimuru-sama~ Ahh~!!" A loud moan escaped before 'she' could close 'her' mouth.

Rimuru's eyes stared at 'her' panting appearance from where he was eating 'her' out. Nemuri felt Rimuru's tongue lengthen and go deeper inside. The sudden change in paces forced Nemuri to fully cross 'her' legs into Rimuru's head.

Then, she felt the tendrils holding her hands on her side began to twist and crawl closer to her body. She looked at them moving worryingly but couldn't do much with her hands bounded and her legs barely holding on with Rimuru's teasing.

"Mh~! Wha, wait!" Nemuri shouted as she felt the slime like tendrils moving to her large breasts. Coiling themselves from the outermost part of her breast, they coiled around it like a snake until they reached the very tip.

Her nipples.

"Ahh~~!!"

The two tendrils latched onto her nipples, with a rough suction. The rough treatment of her nipples while the tendrils continue to coil at her breasts handling and squeezing them for Nemuri's pleasure.

The tendrils felt weird; it was as if they knew 'her' body more than 'she' did. The waves of pleasure were being sent to 'her' brain simultaneously as the pleasure on 'her' lower body.

"What is this~?" Nemuri felt her eyes began to water, the pleasure was getting too much that it was making her cry. "Rimuru-sama! I, I think..."

Hearing 'her' warnings, Rimuru grabbed at her thigh and raised it high forcing himself deeper. Rimuru's tongue played deep inside while also taking it out and making long playful licks and sucking on her nub.

Nemuri's body was beginning to give out as her legs were no longer locking his head but was dangling on his shoulder. Seeing Nemuri's orgasm reaching its peak, squirming, and writhing at his movements, the speed grew faster and more intense.

"Rimuru-sama~!!!" Nemuri cried out.

Nemuri's lips flooded Rimuru's mouth with 'her' orgasm. Rimuru sucked and took long licks to take in everything.

Lowering her legs, he wiped the dripping liquid from his chin.

"Hah...hah..Hahh~~" Nemuri breathed hard exhausted by the cunnilingus.

"For the real deal" Rimuru smirked kneeling between her legs, showing of his member for her too fully see.

Earlier, she could only see it between 'her' breast and a quick glimpse before that. Now that it was fully presented in front of her, inches away from 'her' slit, she couldn't help but stare.

To be able to fully see it now, the deep blush on her face grew hotter and her inside quiver imaging Rimuru ravishing 'her' body with that. "Rimuru-sama..."

'Her' face filled with tears and the two tendrils still latched onto her breast, 'she' looked as appetizing as food was to Rimuru to be gorged with no care.

"Turn around and get on all fours."

Nemuri fully shaded with crimson, nodded, and got up slightly sluggish from the afterglow. Placing 'her' hands on the cold floor and 'her' knees in place. 'She' felt embarrassed as her behind was fully exposed to 'her' master.

Taking a deep breath, she took one hand and pulled at 'her' butt presenting 'herself' to Rimuru.

Grabbing her waist with both hands, he lined himself with 'her' slit.

"Ahh~!"

A sharp moan echoed as the sound of flesh began. He barely worried for Nemuri's first time, with how wet and massive 'her' orgasm was, 'she' was already properly lubricated.

He could fill 'her' inside spasming and tightening around his member, "For someone new to this... your insides sure know how to turn me on."

'She' moaned as the previously silent tendrils on 'her' breast began their suction and coiling once again. Rimuru brushed his hair that was getting in the way as he watched the way Nemuri's ass bounce when their flesh make contact.

"This butt of yours," He grabbed squeezing them roughly, then the tendrils began pulling at Nemuri's breast as if milking 'her.' "And that pair of boobs, having the most lustful body in the forest."

He gave 'her' butt a quick slap as he began to thrust faster. "They are all mine."

"Mhha~!" A new tendril made its move at her lower lip, as Rimuru's member move in and out of her slit, the tendril made its way to 'her' bulging little nub and began playing with it with the same suction as 'her' breast was experiencing.

Rimuru frowned, with one hand grabbing 'her' hair, he pulled her body up. 'Her' hand no longer on the floor and she was now kneeling, like Rimuru's posture.

His hand embedded itself deep in 'her' hairs' roots turning her head. "Answer me, who does this vulgar body belong to?" Cold and frustration leaked from his voice at her unresponsiveness.

The treatment of her body was getting rougher every second she does not answer. She was having dangerous thoughts of not answering, thinking how much more can Rimuru drive her body into ruination.

Clicking his tongue, his other hand grabbed at 'her' throat as he stared at 'her' eyes. "Answer me you whore."

"Khak-!" She felt the hand began to tighten at her neck, 'she' shivered seeing such a dark side of 'her' kind master. "Ha.. Rimuru-sama, Thi- ah! Bod.. belongs to Master!"

Rimuru felt his mind growing into much more darker places seeing the 'adorable' way Nemuri's face was beginning to lose consciousness from both pleasure and lack of oxygen.

"Fuc-!" Rimuru cursed feeling himself getting close, picking up speed. "That's right, tell me again whore who do you belong to?"

"Master, Rimuru-sama~!!" Nemuri cried out as his member was deep in 'her.'

Rimuru hitched a breath as he planted 'her' face on the cold floor. Letting go of 'her' neck and throat, he grabbed at 'her' thin waist and thrusted deep with slapping noises as their bodies collide.

Nemuri jumping between awake and passing out, her body has long orgasm with Rimuru being none the wiser as for every thrust of his shaft, more juices continue to leak from her.

Pressing his entire weight at her body, he finally reaches his own peak. "Shit..!"

Nemuri felt the wave of warm liquid filling 'her' womb. 'Her' body jolted every time more semen was inserted deep inside her.

Pulling himself out of her body, he sat down on the floor of the hot spring. Looking to his side, he can see Nemuri's body slumped down breathing haggardly as semen leaked from her lower lips.

Her expression a mix of both pain and pleasure as her eyes were leaking tears and drool from her lips.

"From now on, all investigation looking for a cure for your transformation will stop." He began as he moved to her face. "You understand why?"

A tendril crawled to 'her' legs, coiling and moving between them.

Nemuri still in a daze crawled towards Rimuru's body, grabbing his still hard member and began to give licks and taking the entire thing to her mouth. "Excellent."

A/N: Probably my second weirdest one-shot. Just a reminder, these are requests lol.
