Hitome's Fillup, part 1 (Patreon)

So, picture this. You've been away for a business trip and come back home to find your previously-rather-flat-chested Hitome has not only gotten an incredible set of implants, but turns out they're also expanders. Not only that, she's been preparing for your return by stocking up on saline to fill her up to whole new levels of expansion.

All hooked up and ready to go, how big she'll go, nobody knows! (that's a lie, but play along).
