This Inflating Bra Commercial Left Me Confused Yet Reaching For My Wallet

Based on my non-existent Chinese skills, I managed to understand that this inflatable bra makes boobs big, BIG, BIG. And I guess it comes with odd sound effects included? Can someone watch please this commercial and translate for me?

I just really need to know whether the voice over guy or the girl with the measuring tape are included with the purchase or sold separately.
