In a last glimmer of hope, Rimuru spoke to Ciel futilely. Ciel felt Clayman through her blissful voice tone and paid no attention to Rimuru. Clayman reached out his hand towards Rimuru.
          
          "Now this is truly the end. I hope you regret mocking me within infinite pleasure. Eternally ♪"
          "S-Stopppp♥ Don't mess with meeee♥♥ Stopp itttt!!!!!!! ♥♥♥♥"
          
          Magic power was emitted from Clayman's palm, corroding Rimuru's consciousness upon contact.
          In the hazy state of consciousness, new pleasure was invoked while Ciel's consciousness suddenly emerged.
          
          (Aaaahhhh♥♥♥♥ It feels so gooooooddd♥♥ Being completely brainwashed by Clayman-sama is sooo pleasurable ♥♥ Finally... finally, I can become a pussy slave ♥ Pleasure will be mine foreverrrr ♥♥♥)
          "Ohh? ♥ Nggu?! ♥ Our master-slave relationship between me and Ciel is being swapped‼♥♥ This means... no longer able to return to the surface――"
          
          It was a swap of deep subconsciousness. One could say it was the prelude for Rimuru becoming a splendid sex slave. The personality filled with hostility that Rimuru had become possessed by Ciel, an immoral core equivalent to or even beneath that of a prostitute. As such, they would become an obedient onahole who could never defy Clayman.
          
          "Abyoooooohhhhhhh!!??! ♥♥♥♥♥♥"
          "Ughyoooooooooohhhhhh!!! ♥♥♥♥♥♥"
          
          Rimuru's consciousness fell into darkness. Their personality was taken over by Ciel and there would be no possibility of swapping back ever again. And like this, Rimuru succumbed in defeat to Clayman.

While Rimuru screamed, it never reached Clayman's ears; instead, only causing the useless big breasts grown by Ciel to jiggle around. These special-made big breasts stimulate Rimuru's senses just by jiggling or being touched, further depriving her of her judgment and reasoning abilities.
          Merely touching the air is enough to make her feel pleasure, constantly in a state of arousal with her pussy dripping milk.
          
          
          "Well, shall we go for the finale now?"
          "Fi... finaaahh... ♥"
          
          When Clayman muttered those words, Rimuru barely managed to respond. The other women were all in the midst of extracting fluids such as squirting and love juices from their pussies and the semen released by Clayman; they didn't even have the luxury to listen.
          Rimuru was still lingering in ecstasy, receiving pleasure from Ciel who had become a prostitute core even more than before.
          No matter what miracles occurred or how the situation suddenly changed, there would be no more resistance. Understanding that, Clayman answered.
          
          "Yes. I think it's about time we completely brainwash your reasoning."
          
          Complete brainwashing. The brainwashing that Rimuru and others had been subjected to until now only controlled their upper bodies while leaving their control and reasoning intact - so to speak, an incomplete form of brainwashing. That's why they were able to talk and verbally resist Clayman.
          It wouldn't be interesting without any response, and moans have an irreplaceable eroticism like nothing else, but ultimately, they are just sex slaves. There is no reason to give them freedom of action.
          
          "No♥ Stop it♥ Shit, you...!♥ Ciel♥ Wake up! Do something about this situation♥♥ Nhii!!♥♥"
          (Ah... ♥ I'm happy, my lord. Now I can finally become your subordinate ♥)

"Oh, resisting, are we? Well, it doesn't really matter. Right, 'Ciel'?" 
          (I have no intention of resisting, my lord. Please bestow your mercy upon this filthy body ♥) 
          
          As Ciel answered like that within Rimuru, changes started to occur in Rimuru's body. Their breasts suddenly throbbed, and their nipples twisted upwards as they began to spray breast milk like a volcano. 
          
          "Ohyo♥★♥" 
          
          Ciel had been entrusted with managing Rimuru's body and skills. Naturally, she also possessed control over her body. She could turn her entire body into erogenous zones and even squirt breast milk without anyone touching them.
          
          (Following the orders of our master, Clayman-sama, all resistance rights of [Sex Slave] Rimuru Tempest will be stripped away. They will be remade into a pure lactating pussy slave.)
          "S-Seriously Ciel‼ What are you saying... ♥♥ Nhoo♥ C-Clayman♥ What did you do to Ciel-san!? ♥♥ Ahh♥ Stop itt! My bodyy ♥ Don't play with iiitt ♥"
          
          Rimuru's body stretched beyond its limits and the overflowing pleasure from within her easily reached its peak. The saturated pleasure overflowed as breast milk from her nipples and love juices from her crotch without any resistance or excuses allowed.
          
          "You shouldn't say things like ‘omae,’ 'Rimuru-chan'."
          "Ohyoooohhhhh!!?! ♥♥♥ Noo... It can't be... ♥ My pussy is throbbing for real... This way I'll really become a slave just like Ciel-san said ♥ Shit! ♥ Fuckkkk‼ ♥♥"

"Let me make you special too, just the way I like it - [I Love Dick Astral Body Expansion]."
          “Oh, ohyooooooooooo!!?♥♥”
          
          As soon as he chanted that, Rimuru's body abruptly stopped and contorted backwards in a strange manner, emitting peculiar sounds.
          
          "C-Ciel-san! Something feels weird with my body! Analysis... can't... oaa~♥"
          (Incomprehensible. Incomprehensible. This power is not of this world. Unable to analyze ♥)
          (Confirmed interference with the astral body. Unable to resist―― Ahh♥ Cannot resist ♥ The body undergoes rapid transformation from male to female form, with significant deletion of skills ♥ Resist... ngiiiiii♥ It's no good ♥ Can't resist anymore♥ If things continue like this, I won't be able to maintain the [Divine Wisdom Core] and will descend into a lower existence... nhi♥ Only successful at times like these ♥ [Divine Wisdom Core] Ciel has super degenerated into a [Prostitute Core] ♥ Demoted and bestowed gifts upon subordinate monsters――)
          "What is this... My chest feels tight!? This sensation is completely new... kyaahhh!? What's up with these boobs?! And my crotch... ♥ Why am I in this form?!♥"
          
          Screams and even self-references distorted, as Rimuru rapidly begins transforming into a female form against their will. Rimuru could become either gender at any time, but being forcibly changed both physically and mentally was beyond their expectations.
          And above all else, Ciel was also affected by this influence.
          Ciel had always spoken intellectually and analytically up until now; however, they now moaned in pleasure due to sharing a host body and underwent perverted brainwashing.
