MilkyBody is an inflation artist who normally does full-body work, but in this one he’s focused just on breast inflation. It depicts an anime demon girl with modest breasts sticking her thumb in her mouth, which blocks air from leaving so that it collects in her chest! Soon she’s inflated the equivalent of several queen size air mattresses, all in her boobs! It’s a good thing they probably weigh so little or she wouldn’t be able to walk! Not that she’d be able to fit those huge balloon breasts through any doors, though.
