Translation (YouTube has subtitles):
Subaru: "Find and point out the sensitive spot of the person in front of you"
Subaru: Who wrote this?
Luna: Luna wrote it~
Choco: There's only one person it could be.
Subaru: Hey you...! This girl is so weird!
Choco: So, that means you should point out Luna-tan’s sensitive spot, right?
Subaru: Wait, hold on... What the... Wait a second... She is even enjoying this!
Luna: Then I’d like it if Shuba could touch my body all over.
Subaru: That’s gross!!! Seriously gross!!!
Subaru: What the heck is this...
Subaru: touches nape
Luna: screaming
Choco: First, the nape...
Subaru: Alright, it's done~
Choco: Subaru touched her nape...!
Subaru: That sounded like a scream from some crime scene, so it's done here.
Subaru: Hey. This is over, right?
Luna: I wish you had been a bit more gentle...
Luna: screaming
Subaru: So loud... My ears are gonna go numb.
Luna: I've been touched all over...
Subaru: No, you haven't. I just poked your nape, that's it.
Luna: I was touched around the nape and near the armpits...
Subaru: What's wrong with you?
