Agreed, big tits in VR is great (both natural and fake). Especially when there is teasing and more relaxed parts with them in your face. I'm not really a fan of aggressive riding where the tits are bouncing up and down because the action is so fast that I cant concentrate on them, especially with video bitrate problems.
SLR basically doesn't care. There are plenty of pornstars/onlyfans models that still have big tits but if they're beyond a C-D cup, they don't really make an effort.
