With as much fun as they had, I don't think anyone can classify it as stupid. Both were laughing the entire time and now both are cleaning up. It's good to see couples having fun like this. You don't see it often, if at all.
I would expect someone with 150 posts here to at least who dasha and demid are. Let alone know that Dasha is the girl. Neither one of them are dasha or demid. The title of the video even says it's their guests.
He might not. He doesn't really fuck that blond girl on a regular basis and he sleeps on the couch. She won't even let him sleep with her. Obviously they are not a couple and he might be angry he has to watch his roommate fuck his girlfriend (I'm assuming the red head is his girlfriend) multiple times a day.
Alina was the same way. She almost every single time wanted to have sex when she had one of her guests spending the night at their apartment. I think Carla is the same way though it is too early to tell with her.
I don't see what the big deal is. The girlfriend can stay with the guy if he's staying. The other girl can either sleep on the couch or with Tanya and Karen. Nothing has to change really especially if everyone gets along.
This was not an attack on you. But a lot of people like to bring the talk of apartment 2 here and make posts of that apartment here. I just like to remind everybody.
