Not much of a big deal here in the States either. At least in my family. Hell, my slut sisters(Yes, they were actually sluts.) would walk around the house half and fully naked all the time. Walking from the bathroom to their bedrooms was a daily occurrence in my household. We used to walk in on each other when we were bathing/showering, to pee or whatever. But, my point is exactly what you stated.
Too many people are caught up in the whole: "If she's kissing me on the lips, she wants to fuck." and "If she's walking in while I'm fucking, she wants to fuck." It's a load of shit. I personally think Azel is missing the time she used to have with the MC, she's feeling lonely now that there's 100 other chicks sharing his time. Before, she only had to share time with Duck... err... Jaime and Shauna, now she's sharing her time with multiple women. So, she takes every opportunity that she can. That, is what's going on. Again, this is my opinion.
