For those things, consent is required, the female's dialogue in what Sana was watching was very much not consensual, so that leaves either consensual non-consent, ie, rapeplay (which is or can be a type of BDSM play), or actual video of actual rape.
As I said, it could be a video of a rape simulation or it could even be a real video of a girl being raped.
It could be either, but rape fantasy is likely since she was trying to bait Sensei into groping her (or whatever she wanted him to do) before the reset after she had a heat stroke in the first place. Sadly I'm not enough of a porn master to be able to tell from a few lines
I still think that Sana just pretended to have heatstroke because as you can see she pretended to faint and when she got to the room she just wanted to be alone with Akira. so much that she talks.
The heat stroke was surely fake:
I honestly think that both of them have forgotten about this event because of the reset, as it seems that nothing has changed between them, even though Rin witnessed Sana doing that to Akira. They haven't shown any indication that they remember that, or perhaps they are avoiding talking about the subject, especially since Akira is not present."
girls who I think don't care much about Akira: Makoto, Sana, Yasui, Otoha, Osako,Yumi.,Nodoka.They were the only ones that came to my mind since they were the ones who showed the least concern about Akira
Maybe, although I'm not sure why else Rin and Sana apparently have a list of things not to speak about:
At this point cosplaying Maya would be a thing for the whole class.
