Mugiwara

Kalifa disguised in the middle of the people while Robin returned to her friend as nothing had happend, after several hours of partying everyone were exausted so they returned to Kozuki's castle to have a good bed to sleep, everyone went to their respective room and almost instantly fell asleep except by two of them, Brook who was composing a new song and Nico Robin who was preparing for her malicious plan.

Nami

For Robin she would be an easy prey, she didn't have obs haki and without her weapon she would be helpless against her new powers, Robin made a little passage on the ceiling that she could use, this way she wouldn't need to use the hall so no one would suspect about what she was about to do.

Robin changed to her symbiotic form and entered the ceiling passage, she quickly made her way to Nami's room, she could see Nami using only her pantie and bra that almost didn't covered her womanhood, Robin slowly approached to Nami, she had only one symbiote clone left so she used her akuma no mi skills to hold Nami, Robin was holding Nami in an eagle pose, Nami woke up scared but she couldn't scream deal Robin's hand on her mouth, Nami could only watch Robin starring her with her malicious eyes while she was dressed as a bitch, after some seconds the black puddle right in front of Robin started to move, from the puddle, emerged a giant cock, Nami became **** as the pennis moved as a snake over her body leaving a symbiotic trail for where it touches, for a moment Robin's hand uncovered Nami's mouth but it wans't enough time to her scream because the symbiotic cock invaded her mouth.

After some seconds filling her mouth with the black substance the large pennis shaped tentacle started to divide itself in several tentacles with a pennis shape on the end of them, the tentacle started to coil around Nami's body, dissolving her pantie and bra, exposing her large nipples and vagina, Robin could only watch as the tentacles started diving Nami's body, on the first moment Nami was crying, fearing for her life but everything changed when the tentacle penetrated her virgin pussy, she had already fingered herself before but this was different, she could feel the tentacle covering her inner walls while another tentacle suddenly dived in her ass, this was the most pleasurable moment in her life and she didn't wanted it to stop, she started sucking the tentacle in her mouth, after seen that Nami wouldn't resist anymore Robin stopped holding Nami, who immediatly hugged the main tentacle, it didn't take to long to Nami be fully covered and reveal her new appearance, she was pair of long boots until her kness, she was using a pantyhose that show her large pussy, she was using a bra that showed her symbiotic nipples and her hair was almost alive in a gradient of black and orange, both woman knew that they havendo enough symbiote to infect the whole crew so they would need to make more symbiote, using their hive mind they reached the conclusion that they would need to sacrifice Brook, the symbiote wouldn't be able to infect him because he isn't alive and his biomass would be enough to infect 1 or 2 mugiwaras.

Brook

Both woman went to Brook's room silently, Brook probably wouldn't see them because he was too concentrated writing his new song, they approached him slowly trying to do not make any noise, "hey Brook" Robin said while she sat on his bed, "Robin-chan ? What are you wear..." Brook was asking but he was interrupted by Nami who fell of the ceiling and put his skull inside her pussy, Brook didn't know what was happening but when he tried to push the woman that was riding him Robin made several arms that holded Brook, after some minutes of the symbiote consuming Brook skeleton they had enough biomass to infect 1 or 2 members of the crew, Nami and Robin looked to each other and said "this was a necessary sacrifice, rest in peace Brook"

Carrot

Robin and Nami now were ready to continue their plan, both woman entered Carrot's room just to have a little surprise, Chopper and Carrot were hugging each other, wearing only their kimonos, just in some seconds Nami and Robin grabbed them and webbed them against the wall, they didn't even stand a chance they were totally imobile and with their mouths sealed, with a malicious smile Robin and Nami started walking toward Carrot while they produced enough pheromones to fill the whole room, those pheromones were different, this pheromones would awake their animal instincts, their reproduction instincts.

Carrot was blushing while her scared expression became a malicious one, Nami and Robin dissolved the web that was holding Carrot, Carrot undressed herself and changed her pose to a doggy pose, showing her rabbit tail and her enchanced pussy, Nami didn't hesitate and started licking her pussy with the symbiotic tongue, Robin started sucking her nipples like a baby, when Carrot left her first moan, a tentacle emerged from Robin's pussy and covered Carrot's whole face, the symbiote that covered her face started simulating the moonlight, as long as Carrot enteredher Sulong form the more the symbiote covered her body, after some seconds Carrot was using a bunny-girl suit with the white spider symbol on her stomach, Carrot started staring Chopper with her dark eyes, Chopper was using his human point to avoid the effects of the pheromones but it still had some effects at his body, the web that was holding him was elastic and sticky so he wans't able to escape, he could only watch Carrot walking on his direction in a seductively way.

After Nami and Robin left the room by the ceiling Carrot grabbed his pennis and startet licking his pennis until it became hard as rock, Chopper tried to resist but he was unable to move so he could only wait and watch while Carrot sat on his cock and started boucing, she was a sex machine and even after chopper started cumming she didn't stop, she made the opposite the started bouncing even faster, the web slowly made a cocoon around his body, after some minutes of Carrot bouncing, the cocoon melted and showed his new form, it was almost like venom(Eddie brock) but with 2 differences, a pair of great and sharpen horns and a great cock, his symbiotic cock was 3 times bigger than his normal cock, both looked inside each other eyes and started a savage sex, like 2 animals just following their instincts, the symbiote changed their biology in a way that their cum would become new symbiotes instead of normal cum, and this was their final plan, Carrot and Chopper would make and send new symbiotes while Nami and Robin would subdue the rest of the crew.

Sanji

Nami and Robin continued with their plan and their next victim would be the easyest one, Sanji.

Nami used the symbiote skills to undo her clothes and become naked, she entered the room while Robin was on the ceiling acting like a safe-guard, Nami slowly approached him, when she was near enough she laid on him, pressing her huge breasts against his mouth and nose, Sanji woke up on the same time, for the first moment he didn't understod what was happening but when he looked down he almost passed out by his nosebleed, he had never been so next to Nami's huge boobs and the check-mate came when she said seductively "Do you want to make a baby ?, Sanji-kun ?"

Sanji and Nami were covered with Sanji's blood and Sanji finally had passed out, as Nami had planned, Nami put her hand at her pussy and grabbed a new symbiote and put it on Sanji's nose, the symbiote entered his nose and started covering his inner organs, after some seconds his cock started ejaculating the black goo that covered his own cock and made it much bigger, Nami knew that she needed to hurry but she was blinded by the lust and started bouncing on that symbiotic cock but this wasn't all bad because his symbiotic cum would only produce even more symbiotes, what would make much easier to infect the strong ones like zoro and luffy, she bounced there until the while room was covered with symbiotes and now all the infecteds knew that no one could stop them.

Yamato

Robin waited patiently until Nami and Sanji were done, she called some of the symbiote to come with her and she went to Yamato's room, Nami did the same, she went to Carrot's room and called the symbiote, she was surprised by how much symbiote cum was there, they were almost drowning in their own symbiotic cum, Robin and Nami went to Yamato room and stood on the roof and started filling the room with the symbiote, the black goo quickly covered Yamato's body, suddenly Yamato woke up scared seeing that black goo but it was too late, the symbiote penetrated her ears turning her brain off, the black goo covered her face making a cocoon around her and started the bondind process.

Inside Yamato's mind:

After Yamato felt something invading her ears everything became black, suddenly she found herself inside a dark room, Yamato looked around but the only thing that she saw was that black goo filling the room, suddenly the black goo shot a large tentacle at her direction, Yamato dodged it easily but she saw her kimono melting and becoming that black goo, she tried to pull off the black goo but it was too sticky, before she could do anything she was already immobilized but this didn't her will, she could see emerging from the black goo a strong man fully covered by the black goo with tear eyes and a mouth with a long tongue, his pennis slowly became erect, when it was full erect it had 20 inches, Yamato closed her eyes when she felt his tongue licking and playing with her huge breasts, she had never felt as a woman until the symbiotic man penetrated her virgin pussy, Yamato could only moan deal the pleasure but she still didn't give up until that moment, without Yamato note a tentacle emerged behind her and without any warm penetrated her ass, Yamato started cumming and as long as her cum covered her legs the more the symbiote corrupted her mind, Yamato could only moan and ask for even more symbiotes, suddenly she woke up on her room wearing her new "suit" she wearing a slimy leather jacket and a little pantie, Yamato saw Robin and Nami leaving the room, she was too tall to enter on the ceiling passage so she started masturbating herself with a symbiote dildo.

Usopp

Usopp would be an easy targed so Nami went to the other rooms taking almost all the symbiote while Robin took only one and entered Usopp's room, she undressed her symbiot pantie and produced some pheromones inside her pussy, she quietly approached him and sat on his face and put his nose inside her pussy, Usopp woke up scared felling something heavy smashing his face but the only thing that he saw was a great butt and a tight ass, he tried to move bit he wasn't strong enough, Robin was pleasuring herself using his nose while the symbiote that she brought slowly covered the helpless Usopp, she used his nose as a dildo until the symbiote covered him and made a cocoon to start the bonding process, meanwhile this Nami didn't stopped working.

Jinbei Franky Zoro

Nami knew that she couldn't handle against them, they were too strong for her even with the symbiote and they weren't so stupid like sanji or Luffy so she couldn't have the fun that she wanted, she decided to use the B plan, she sent one little symbiote to each one, the little symbiotes entered their ears and started corrupting them by their brains, this would take longer to corrupt them but this way there wouldn't be any resistance.

Luffy

After starting the B plan with the rest of the crew she went to Luffy's room, she approached her captain and started kissing him but it wasn't a normal kiss that kiss started filling his body with symbiotes, the brainless Yonkou's body started to change, it was almost a gear 4 but instead of air he was filled with symbiotes, he's will was one of the strongest on the world but he was probably one of the dumpests on the world so the symbiote convinced him to bond easily and smashing his mind on the first moment, Luffy wasn't like the others, it wasn't a mix of his mind and the symbiote, he was now only symbiote and the new King of the world, the symbiote King had a mission, cover every island and sea with his symbiosis.
