Tit bomb

My mom said to me, early in the pregnancy, "Your tits are about to explode." Well, they have remained pretty small, their usual selves. Just kind of heavier, fuller... They've gained density, and my ribs have expanded to accommodate all my organs, but my breasts haven't really been much bigger.
Until now. The tit explosion is happening.
I know it's a little shallow, but I do hope I come out of this with some cleavage that does not require too-small dresses or duct tape.
