Either in how much weight that is or that she broke yet another bar.

Here we see young Iona indulging in one of her favourite activities. Next to science, fucking, being worshipped and adored and maybe eating those worshippers. This happening could well have been what lead to this little laugh here. Being the avid breeder that she is, her bustsize is bound to change every so often, going up and down with her pregnancies (or... somethingsomething dragonanatomy) and here it seemed like she forgot just how big she was as she lifted the weight and her boobs of steel promptly repelled the several tons worth of weight.

Of course you're free to imagine your own little story how this came to pass.
