Ok, we know someone was in the room at some point, Aaron said it was April who liked to sit in the corner. It could have also been Kayla, we just heard a female voice once, nothing further. He also read the same superchat something like 10 times, and said "oh shit we're still on" before the apparent bj, was that also him telling her to stop? He could also been verbally reminding himself the camera was still on, also in line with making a shitty dsp masturbating joke and the fact that he had said it earlier and was at a point where he verbalised everything he was thinking.
It wasn't Kayla, we know this because she didn't sit and watch him stream in the past. The whole meme about the fact he kept looking off to someone in the room - this was recent, since the polycule - we can reasonably infer that this is because a new person was watching him stream. It wasn't Aaron, it doesn't match Kayla's previous behaviour and Aaron had stated that April did it - evidence points to April being in the room.
However if you want to be specific about things lets run through this in a play by play.
Nick is rambling about something or other, and then looks down in the direction of his crotch and states "Why would you do this, why now?"
He then appears to be either jerking it, or reacting to someone else playing with his
polish sausage, before exclaiming "why is this camera still on... we'll play the credits, no what we will do is we will sit here". Notably, what is incredibly telling for me is that you can see Nick look at his crotch, then every time he looks down he is looking at a different position. The positions of where he is looking track exactly with how someone would have to move to get back into the corner from under the desk without being caught by the camera. He also smiles at whatever he is looking at.
In addition to this, when I turn up the quality and turn up the noise I agree with Warski - you can hear a belt being undone. I personally think you can hear his mic picking up blowjob noises from under the desk. Although audio is always questionable when it is not entirely clear, so take that as you will.
The wider point is that it is highly likely April was in the room, and Nick is looking at her, watching her crawl under the desk and back, he smiles at her and reacts to whatever is going on as if someone is sucking him off. Yet we are to believe that this is some crazy theory.
I'm baffled how everyone is acting like we have 100% verified proof that it happened
The first thing I said is that there is no confirmation. Sure, it could be a stupid DSP joke, it could of been him masturbating, but we have to acknowledge that all the available facts would indicate that he was being sucked off. People speculate on this forum all the time, as far as I am concerned the basis for these speculations is relatively solid.
