(3rd PoV)
Sakura was wide awake as she slept with Horikita.
Being chased down by the stalker was scary. But... if she had asked help from the authorities in the first place, she wouldn't have to worry, being scared this whole month.
Horikita hugged Sakura from behind, whispering to her.
"You alright now?"
"Y-yes!"
Horikita sighed and decided to just sleep. This girl wouldn't really calm down.
'Suzu?'
She didn't respond. She has probably fallen asleep.
After a while, both Horikita and Sakura fell asleep.
Suzu stirred, not feeling well. She felt like she didn't have a lot of energy, and was feeling weird. Like she was sick.
Still asleep, she coughed out something from Horikita's mouth, and it directly fell on Sakura's neck.
A new symbiote. Pink and black.
It injected some toxins into Sakura's blood via her neck, making her fall in deep sleep.
Then slowly, while making sure that its mother Suzu doesn't wake up from noise, it started spreading over Sakura's body.
It covered her upper back, and then started spreading over her chest.
It ate away at her pajamas, since they were getting in the way.
It then contested in what to do. Horikita was holding her waist.
So it started bonding with Sakura's head then.
It's tendrils creeped up her neck, and started covering the back of her head and covered each strand of hair.
And then, it started covering her face. It entered through her nose, and forced its way into her mouth.
Sakura woke up, startled, and tried to scream. But the symbiote was getting inside her mouth, making her gag. She couldn't see anything due to symbiote covering her entire head.
Horikita woke up due to Sakura's movements, and froze.
'Suzu! You gave birth to a symbiote!?'
Suzu woke up, and saw what was happening through Horikita's eyes.
Suzu now a Mumma too?
Horikita sighed and let herself be covered by Suzu, and tried to establish a hive-mind sort of connection to Sakura's symbiote.
'Be gentle with her.'
She commanded, and received an infant-like agreement.
The symbiote spread over rest of Sakura's body, eating everything in its way.
Watching the scene, Horikita couldn't help but think that this looks really hot.
"Sakura, no need to be scared, I am here."
She said, but Sakura wasn't going to calm down.
The symbiote completed covering her from outside, and from the inside, it has entered her brain.
It felt her fear and shyness from the world, but at the same time confidence when she wasn't being herself in front of the world and hiding behind a fake identity of Shizuku.
It...no, Shizuku felt like her other self, her host, needs to be protected beneath Shizuku.
The symbiote, naming itself, herself, Shizuku was her outer self. And she would protect her inner self Sakura, her host, from the world.
Shizuku completed bonding to Sakura, and Sakura's eyes fluttered open.
She saw Horikita in a Venom suit.
'Am I in a Spider-Man universe!?'
As she started to panic, her eyes fell on herself. She was also covered in a symbiote now. Pink and black, with a small black spider-symbol on her chest.
"I look so cool!"
She said excitedly, and hugged Horikita.
Wait!? That's not her! Her body and mouth moved on its own!
She was horrified. Will she loose control over her own body... to a symbiote?
A voice rang in her head.
"I will protect us. You remain our inner self. No one needs Sakura. Everyone is attracted to Shizuku."
Horikita, who was hugging Sakura, found it unusual. Why wasn't Sakura freaking out?
"Give back control to Sakura."
She said, and 'Sakura' froze.
Then, the symbiote retreated from her face, and asked in confusion.
"We are Sakura."
And then, her smile turned psychopathic.
"But better. Hmm, we are Shizuku. Should we change our legal name?"
Now, Horikita was scared. It seems like the symbiote has taken over Sakura.
Suzu forcibly controlled the new symbiote Shizuku with her hive mind, and Sakura was finally in control.
"W-what happened!? Please help me!"
Shizuku was struggling to fend off Suzu controlling her. She lashed at Horikita, using symbiote tentacles.
Horikita's razor sharp claws cut the tentacles, and she felt like there was only one way for Sakura to retain control.
She grabbed Sakura's crying face, and kissed her.
Sakura's eyes widened.
Horikita spoke inside her mind.
"You are not unneeded. Sakura, Shizuku is your personality. You are Shizuku. Not the other way around. Control your symbiote. And symbiote, your name is Pink. Your job is to help Sakura, who is Shizuku. Not hijack her body!"
With the power of love, Sakura should be able to win, right?
