kitek posted a translation about it. She's been at least 3 times that we know about, twice with Danaya. They go with Irma's friend Alex, who is desperate to fuck her but she has never let him and probably never will, but he is happy to take them so he can see her naked
It's a swinger club, so there is definitely sex happening there, however from what we have heard neither Irma nor the other girls have had sex with anyone there. It seems likely that she will at some point though, although we do not know that this is where she is this evening. From now on, whenever any of the girls leave the apartment people will be claiming they're at the swinger club, no matter if there is any truth to it
Angie looks like she could use another girl to play with. She's getting on very well with Nicole and Estelle but those two come as a pair and we know Nicole is straight as an arrow. Danaya would be nice but she is leaving soon so probably don't care to get too attached, and the other girls are all in B1. Maybe whoever replaces Danaya will be a good friend to her
I'd say the girls are a bit too dressed up for that particular type of club, and Danaya putting on makeup is not so clever if you're getting in a pool when you arrive. But wherever they go I hope they come home not too late, very horny and preferably without any dudes (just my opinion!)
