I imagine that Gia was so tired of waiting for Ian to give her a good pounding that she got to the point of not caring whether there were shitty bedroom cameras catching the whole thing.
Which brings up something I've noticed in each of the apartments. They've all seen the feeds and know exactly what the cameras can and can't see, and they know which cameras provide a good feed and which don't. Take Gia and Ian for instance. She tries very hard to not show herself nude anywhere but the bedroom, which happens to have some really shitty cameras. When Anton was pounding Alina's ass last night, he knew exactly which angle to position himself and the covers at to keep from showing a lot. Of course, I think she was just glad that he finally got off the damn computer long enough to touch her that she, too, did not care.
One last thing, I vote to change skinny and chunky to hottie and chunky. If hottie weren't a carpet muncher I'm pretty sure she could have her pick of guys.
