Right before Kosaka still kept fighting with Renka on the floor while they were asking each other on them why did they need to keep away from Yakubo Mio.
Ogawa: please stop fighting both of you
Renka: sorry we can stop fighting each other and if you hurt yourself later Kawata Hina is worried sick about you
Kosaka: argh…fine I will stop but can you tell me why did you make her like this Tamaki
Right before Tamaki was telling them the long story about Yakubo Mio had brainwashed her project on something more than other Hinata performances.
Tamaki: I plan to make Yakubo don't remember each of the member's names but I put a few names only
Flashback back went she was inside the TBS studio and there have Yamasaki Ten along with the 3rd gen member who are worried about Yakubo Mio's condition she had to brainwash her mind and set thing the right way before they know that Yakubo had changed her thought into someone else or a different person.
Tamaki: Kanemura let me do this on Yakubo's brain
Kanemura: are you sure about this
Tamaki: yes I'm sure but don't tell the Nogizaka member about this project just between us
Meanwhile, Kanemura Miku agreed with Tamaki's project, and nine months later went Yakubo was waking up from her deep sleep she woke up from the tech bed and she can only see Tamaki who are standing there waiting for her to wake up.
Tamaki: good morning Yakubo Mio how is your body felt like
Yakubo: my body feels like light but why I can't remember anyone's name inside my brain
Tamaki: don't try to force yourself again just like last time
The flashback has ended and back from the present day and Tamaki had told them the truth being brainwashed by Yakubo Mio's thoughts and not remembering anything.
Tamaki: that's my story about the Yakubo project
Kosaka: so it was all your fault then
Tamaki: yes it is my fault and please don't scold Yakubo just scold me
Inside the experiment room together with Yamasaki and Yakubo, they were doing the same as Renka's experience with her but she had a different kind of thing right at Yamasaki and she was pushing Yamasaki against the door of the room.
Yamasaki: woah…Yakubo just relaxes there, can you?
Yakubo: sorry I can't but I need to you kiss me on my neck
Yamasaki: eh? What kiss you on your neck and why?
Once Yakubo was using her telekinesis power on Yamasaki's hand and she want to control herself but she can't control out of the blue, she was forced to kiss Yakubo on her neck and she had to sound coming out of the mouth while another can hear them have some alone time together inside the experiment room.
Tamaki: what the hell is going on here?
Renka: they are doing some kind of experiment thing inside
Tamaki: like what kind of experiment they do inside Renka
Back inside the experiment room and Yamasaki still kept kissing Yakubo's neck right before Yakubo grab her right hand and tries go to touch her below her pant suddenly, she can feel something is on her behind her back.
Yamasaki: what the hell is that, Yakubo?
Yakubo: I'm sorry Tenchan that was something you can't imagine why
Yamasaki: huh…? And what?
Out of nowhere, Yakubo tied both of Yamasaki's hands together and was put on top of the empty desk table she going to start to open her skirt and she went inside and Yamasaki can feel like hurting inside her belly.
Yamasaki: Yakubo…why my belly felt so damn weird
Yakubo: because it is called sex Tenchan
Yamasaki: wait…we are doing some sex together but you are a girl
Yakubo was pulling down her black long pants along with her boxer and Yamasaki can see that Yakubo had a futanari huge cock that sticking out from her pant and she was putting an XL condom onto her futanari huge cock on it.
Yakubo: can I move Tenchan
Yamasaki: please be gentle with me Yakubo it is my first time
Yakubo: sure I will go slow if you want to but if you want to make it go faster just whisper in my ear
Later Yakubo was moving inside Yamasaki's great fucking pussy and suddenly Yakubo had cum a lot of her futanari white sticky sperm inside of Yamasaki Ten pussy.
Yakubo: Tenchan…Tenchan I'm about to cum right inside of you
Yamasaki: please give it to me and I want to feel so breathless with you Yakubo

They can feel like something is exploding together with her but other can hear them moan very Yamasaki had to shout just some kind of adult moan and they finished the sex alone with Yakubo Mio and next is Sugawara Satsuki who are going to taste her pills.
Yakubo: Tenchan can you call Satsuki inside the room

Yakubo: sure I will do that
Sugawara was scared of Yakubo's looks and she was doing the same as Renka and Yamasaki she was sit sitting on the chair and she did not tie both of her hands or legs to the chair itself.
Sugawara: wait…Yakubo please wait up
Yakubo: we can do it quick trust me you will love it
