“Leo, where the hell are we going?” Raph asked his blue-bandana wearing brother.
“Shh, it’s a secret,” Leo insisted to him as he led him through the sewers. 
“I hate secrets…” Raph muttered as him and Leo reached a ladder heading up to a grate. 
“Up here,” Leo said as he started climbing the ladder. Raph rolled his eyes before following him up. 
“Always following the leader…” Raphael muttered as he climbed behind him.
‘And you won’t ever disobey again soon,’ Leo thought as he opened the grate to let themselves in the location. Leo quickly got inside and Raphael quickly followed him into a wide room that appeared to be a lab of some sorts. “The hell? How long has this been here?” 
“I don’t know. I just found it yesterday and wanted to ask you about what we do with this place,” Leo said as he examined a nearby machine, a large, metal construct that had a conveyor belt to lead items inside. 
“Do you know what this place is for or what this thing does?” Raph asked him as he got next to his brother to examine it with him. 
“No, which worries me. I’m afraid of just leaving it alone,” Leo said to him, “but I know Don would be interested in it.” 
“That brainiac is always interested in stupid machines,” Raph scoffed as he got on the conveyor belt to get close to the inside of the machine. As he got close to examine it, Leonardo was slowly making his way to the control panel. 
“What you doing, Raph?” the leader asked his brother. ‘I don’t even have to force him onto the belt…’
“I’m just wondering what’s in here,” his subordinate said as he examined the closed door that leads inside the contraption. Raph brought his sai out and started trying to get inside. 
“Raph, do you think that’s wise?” Leo asked him as he got ready to activate the machine. 
“What?! We got to figure out what it does, right? Now help me out!” Raph yelled at him. 
“Well, I can open that door easily for you,” Leo said as he activated the machine. 
“Huh? Woah!” Raph yelled as the door opened for him and metal claw came and grabbed Raph by the wrists and dragging him inside as the conveyor belt moves forward to help him along forcibly. “Leo! Help me out!”
“No, Raph. This is exactly what you deserved,” Leo said to him. 
“What? Leo! This isn’t funny!” Raph said as he struggled against the arms, using every bit of muscle in him. 
“Good-bye, Raph. I’ll come back when you’re done,” Leo said smugly as the door closed, leaving Raph inside the brightly lit machine. 
“Damn you, Leo!” Raph yelled as the arms started removing his gear, taking away his sais, belt, kneepads, elbow pads, and his mask, leaving him naked inside the machine. Metal arms came for his face and quickly inserted speakers in his ear slits, transparent screens over each one of his eyes, and adding a set of rubber lips to him that forcibly contorted his mouth into a lustful smile. He was weirded out by these additions, but continued to struggled as he came to the first part of the machine, a pit of black liquid. He was carried off the conveyor belt and made to dangle helplessly over the black abyss. As he was hung above the pit, a hand came to his pelvic slit and started pleasuring it, making Raph moan as his dick was slowly exposed and made to be erect. As soon as he got erect, the arms lowered him into the pit and dunked him in it, surrounding him in darkness as he was made to float in it. 
Raph was locked in a state of bliss as he drifted in the never-ending darkness. He felt the liquid surge inside his mouth, suffocating him at first before he felt it lighten and making him breathe easy inside the black goo. He felt it all over his body and he could feel his body changing. His finely-toned muscles slowly went away, leaving a lithe body. His shell was flattening and becoming impossible to notice. His waist started becoming constricted and become thinner in size. Most importantly, he felt his dick start to curl into itself. He was becoming a new Raphael. 
After what felt like forever for Raph, he was brought back out of the pit, the black goo dripping off him. Heat went over his body and completely dried out all the goo and make sure nothing more was left, leaving him completely encased in the black rubber substance. Raph now looked like a black, shiny drone. All his muscles were gone, his shell had practically disappeared, his waist had shrunk several inches, his ass had become a circular hole, and his dick had become a giant bulge, leaving him in a state of denied climax. 
The horny doll was moved forward to the second part, where paint sprayers came out to give the doll a fresh coat of paint. Pink paint came out and started painting him up, completely painting his feet and up to the middle of his lower legs. Hearts were painted on his knees before three stripes were added to the middle of his thighs. An outline of panties were painted on before a pink heart was painted on his bulge and on each of his ass cheeks. Five stipes were painted on his stomach and his waist before a bra was painted on him, a heart at the small of his back where a clasp would be and a heart at the center of each of his cups. His shoulder had a heart painted on it with a circle enclosing it before adding three stripes to his upper arm, five stripes on his lower arm, and another heart on his elbow. Hearts were painted on his palms, back of his hand, and his knuckles before painting nails on his finger. His neck was painted up before they went to his head and started painting a face, putting on pupils, irises, eyeshadow, eyelashes, and eyebrows with hearts on his cheeks and making his plump lips pink. 
With that, Raph was moved to the next stage of the process and a wide variety of clothing came to him to transform him into a playboy bunny. Pantyhose were brought first, rolling up his legs and being at his hips, a hole for his ass added in as well. A pair of thin, pink, latex panties were slid up his legs before being placed on his hips, hugging his groin tightly with a small hole for his circular sexhole. A rubber, pink corset was brought forward and wrapped around the rubber doll before tightly cinching it up, further thinning his waist. Pink, six-inch stilettos were brought to him and forced his feet into them, adding a few inches and making him have to move around at such an uncomfortable angle now. A pink, rubber collar was attached to his neck with a pink bow attached to it and tightly knotted. A pair of rubber, pink gloves with large cuffs were placed on his hands, tightly encasing his three-fingered hand. A pink, rubber headband with bunny ears attached to them were brought forward and affixed to his head. A pink plug with a bunny tail at the end was the last object, being pushed through his ass and making Raph shivered as a cute, bunny tail now covered his sexhole. Pink bows were further added to his cuffs along with a rubber garter to his left leg before a pink rosette was placed on both sides of his hips to complete the look. 
With that, the newly-dressed playboy bunny was brought forward for the final stage of the process. Raph was still struggling to escape as he felt something inserting itself through the back of his head and he gasped at it. The device started making alterations to his mind and Raph groan at it. His love for muscles and strength was change to a love of being slim and weak. Hs need to be the dominant turtle became a need to be dominated. Instead of feeling the need to show off his manliness, he felt he had to make sure his sissiness was on display at all times. He was made to enjoy the thrill of being humiliated in his skimpy, demeaning outfit. His love for women was replaced by the need to be penetrated and suck men off. 
After some time, the device remove itself from the back of his mind and moved him forward, Raph no longer struggling now. Microscopic cameras and microphones were brought towards him and placed on his eyes and ears before being turned on, finally giving Raph his ability to see and hear again. Raph hummed happily as he looked himself over under the bright light at his new, sexy body. As if knowing that Raph would want to examined himself, a large mirror came out for Raph to examined himself and Raph purred happily at seeing himself and examined his new look closely. He looked at his thin waist, his angular heels, his permanent smile, his lovely bowtie, his cute bunny tail and all of it in pink. ‘I look like such a cute playboy bunny!’ Raph could not help but think as the mirror was taken away again and the arms proceeded to package him up. The arms wrapped tape around his heels, ankles, knees, wrist, waist, shoulders, and his mouth before finally sending him out of the machine to the end platform. 
“Hmm~ you look beautiful, Raph,” he heard a familiar voice and moaned happily as Leo appeared in front of him. “Heh, and very excited too.”
‘Someone as beautiful as you always turns me on!’ Raph thought to himself as Leo started caressing his rubber body. 
“Hmm… a playboy bunny is a good look for you,” Leo purred as he groped his ass, sides, and thighs. “Really shows off your features.” 
‘Thank you, Leo,’ Raph thought happily, as he enjoyed the groping before Leo swept him off his feet. 
“Now, I believe I need to take you to my… special place,” Leo said to him as he went back to the grate they used to get in and dropping down to the sewers. “I made a special place for just you to live in.”
‘Oh? Thank you, Leo~’ Raph hummed happily in his mind as he was carried through the sewers. After several minutes, they reached a small two-room area that Leo had recently cleaned up. All that was really in the first room was a small table with two chairs while the second room had a bed and various sex toys around the room for Leo to use on him and a full-length mirror. Leo brought him to the bed in the room and quickly removed the straps of tape off him. 
“There. Now, I’m going to establish some rules here, Raph, and you must follow every single one of them. Understand?” Leo asked the pink sissy. 
“Of course, Leo. I’ll do whatever you want me to,” Raph said as he spread his limbs out on the bed. 
One, you are never allowed to leave this room,” Leo told him. 
“Of course. I’ll wait for you whenever you’re gone,” Raph promised to him. 
“You better. You wouldn’t like me to punish you,” Leo warned him before continuing. “Two, don’t attract any unwanted attention here. Don’t yell out for anyone. You only need me.” 
“I will do that,” the sissy nodded to him. 
“Good. Rule three, follow every order I give you. Don’t resist,” Leo warned him. 
“I see no reason to,” Raph hummed to him happily. 
“Good, now I think it’s time to test you out,” the ninja turtle grinned as he slowly got his cock out of his slit, precum already coming out, and Raph could barely hold in his excitement as he eyed it. The cock was easily nine inches long and Raph wanted it all in him. “Ready for it?” 
“Yes! I want it really badly!” Raph insisted as he nodded his head to him eagerly. 
“Good. Give me a good blow job,” Leo ordered him and Raph nodded before he opens his mouth happily for him and took the large cock slowly, savoring it. 
‘Hmm~ taste so good~’ Raph thought as he easily took half of it in. 
“That’s a good slut,” Leo said as he patted Raph’s head and played with his fake bunny ears as he thrusted his cock inside the mouth. Raph’s had a grooved mouth now with no teeth or tongue visible inside of him, only rubber covering it. “I want you to take it all in. That’s what a good sissy does.” 
‘Yes, master! I’m a good slut!’ Raph insisted in his mind as he took in more of the cock in his mouth. 
“That’s right. Get more and more of it,” his master insisted to him and the sissy did so, swallowing more and more of the dick until he got all of it in his mouth, pressing his lips against Leo’s slit. 
‘I got it all! Yes!’ Raph thought in triumph. 
“Good slut. Now suck it,” his brother ordered and Raph did so unquestionably, sucking his dick forcibly, but with care. “Yes… that’s it!” Leo moaned to his brother as he started thrusting into his brother’s mouth as well to pleasure himself. He gyrated his hips to move it around his mouth and Raph got giddy about that. 
‘Yes! Keep doing that and fill me up!’ Raph begged in his mind as he quicken the pace and worked to make his master moan in pleasure. 
“Yes! Just like that, my cute cumslut,” Leo praised his sissy as he kept thrusting harder and harder into their mouth. This kept up for several minutes, until, after much moaning, Leo cummed inside Raph’s mouth with a loud yell of ecstasy. Raph moaned happily as he felt Leo’s cum cake the inside of his mouth. Raph gave him one more suck before pulling back to give Leo his completely clean cock back. 
“Hmm… thank you, Master Leonardo! Did I do a good job at pleasing you?” Raph asked his master. 
“Yes, you did, my favorite servant,” Leo said to him before pointing to a metal box on the floor. “When I want you clean, use that. I don’t want a dirty slut all the time. Savor this for now, but use it before I come back.” 
“Of course, master,” Raph nodded. 
“Good,” he said before pointing to the mirror. “When you want to, feel free to pose in front of it to get a good look at yourself. I’m sure you need to appreciate your look and I have camera behind there to appreciate you in my room as well.” 
“Oh, I’ll always pose for you if you’re watching. I want you to appreciate me, after all,” Raph told him. 
“And to make sure you behave,” Leo reminded him. “Remember my rules or I will punish you.” 
“Of course, master. I won’t deviate from your orders,” Raph assured him. “I’ll be a happy little slut for you.” 
“That’s a good sissy,” Leo praised him as he patted him on the head before forcing his cock back into his slit. “Now, I got to go. I can’t just lounge around all day, like you.” 
“I understand, master,” Raph nodded to him. 
“Good. Now, while I’m gone, a little gift for you,” his master said as he got a controller out of his belt and pressed it. Raph moaned as he felt the plug in his ass activate and he laid on the bed in pleasure as it vibrated inside of him. “You have fun with that for the night. I’ll be back hopefully tomorrow where we’ll have more fun.” 
“Thank you, master…” Raph moaned to him as Leo started walking out. 
“You’re welcome, my loyal sissy. Have fun,” Leo said before exiting the room and leaving Raph to caress himself on the bed, moaning in absolute pleasure. The old Raph was truly gone, leaving nothing but a rubber whore for Leo to use and he was happy with that. He needed nothing in life, but to be used like the rubber whore that he was.
