I had a 4 hand at chun a couple months back. It was with happy and I forgot the other girls name. I believe she is gone now. Was very thin with A cups and not too experienced either. But anyways, the girls didn’t seem like they wanted to be doing the four hand. The masks stayed on both of their faces the entire time, but in sessions with these girls solo they would take the mask off. I think they had to take extra precautions both being in the same room, and now maybe they just don’t do it at all.
I’d lean more on the side that they were probably busy or something.
