Basically they're talking about the armpit fetishism how's growing up, like more armpit models and people paying to see their armpits. There are 2 models, a man with white tank top and a woman with black tank top. So they're start smelling and at some point they're invited on the set. One of the hostess has the idea and ask them if they're dating, the female model says she has a girlfriend but the male model is single, so the hostess says: "Wel I can do it to you" and asks if they're ticklish. The male says a little bit and the female says she is. She quickly tickles the male's armpit and then she quickly tickles the female armpits. At that point the other hostess says, hey you're touching them without their consent, and start talking about been consent even it's playful tickling, this is a little more sexual so always ask for consent. So then the "tickler" raises her arms and says, "well now you can tickle me" and the female model quickly tickles her armpit.
I'll try to see if I can extract the video and publish it here.
