yeah, my autism picked up on that a while ago too. Ive assumed for a while it is because her husband is doing the shooting. That's why I was so surprised by the onsen set earlier this year, because it was obvious he was the one filming, and there were nip slips and a lot more skin in it than in her normal shoots. If you look at some of her older stuff too, you'll notice that she has the more professional photos and even videos then sometimes, the next item in the set will drop in quality to a video or two or some gifs of her, and those are always way hotter because it's her alone in a room filming herself.
while I loved her last set, dont take it for granted nips will be a regular thing now. I'd love to be proven wrong, but she'll drop a super lewd set, and then not get back to its level for months if ever again.
