Well she ate it obviouslyliterally where is the cup though?
No really, though, I think I’ve been ninjad but the cup on (her) right is in tact and holding what presumably is her smaller boob. The(her) left boob is either big enough so that the cup isn’t showing or that cup is not there at all. Normally cups will look like they do on (her) right if there’s not enough boob to fill it, so you just get the cup showing on a tight shirt
Now in her case she’s fat so it’s not that she doesn’t have enough boob to fill her cups. It’s that there’s no support in her other cup which means there’s no wire, significantly more boob, or no cup
Idk of any woman who would wear a one cup bra. It could possibly be she just has one huge left tit or no underwire support.
