Your eyes hone in instantly to her bust, captured within that lace. That red lace, hiding her nipples, cupping her breasts when you should be the one doing it. But her taking it off might not be enough — you want it completely out of the way. You hastily find the slider “Boobs” which is set at a ‘C’. There’s a lot of room to grow in this slider bar (and a little bit to shrink), mimicking just how much you can make her change. What size do you change her to?
