I can’t tell if she’s doing that on purpose or not.

Only think in... milk direct from origin

Searching chanta + breast grab I would say a good firm grip around a foxtit or two has become more of a "tradition".

Or Yukari is stuffing the tabard up underneath Ran´s breast for the sake of looks.

I think she was just reaching out for the glass without really paying much attention or looking... and grabbed a fox tiddy instead.

Damn how is it so big? The glass of wine that is

Knowing her, the most plausible is pretending that she intended to do that while she actually wanted to just grab the breast.
