"Yes. Afterall, that's what you're supposed to do with food." Robin giggled as she continued to rub Nami's belly.
Nami had to admit that Robin rubbing her belly felt good. Not only that, but she felt satisfied after eating Hancock and feeling her kicks as Hancock attempted to escape.
Hancock continued to struggle though began to weaken as Nami's stomach worked hard to digest the empress. As Nami's belly shrank, her breasts and ass began to grow in size. Soon, Hancock was fully digested as Robin rubbed Nami's potbelly.
"Well, looks like our empress is finally done." Robin giggled as she pulled back and admired Nami's new body.
"Oh my, Nami. You look stunning."
"Really?" Nami excitedly got up and walked up to the mirror. As she did, her breasts and ass began to jiggle, now fattened up by Hancock.
"You aren't lying. Hancock does look better like this." Nami said as she grabbed her breasts and slapped her ass.
"Indeed." Robin said as she continued to admire Nami's body.
"Wait, since I digested her, doesn't that mean I get her Devil Fruit?" Nami became intrigued.
"I don't know, try it out."
Nami began to shape her hands like a heart. "Mero mero mero" Nami said as a beam was released from her hands.
"Looks like I did. Well, looks like I won't be that weak anymore." Nami said, giggling.
The only 'bad' part of digesting Hancock was letting her go. Nami sat on the toilet, releasing whatever remained of Hancock. In reality, Nami felt nice releasing what remained of Hancock. As she finished, she looked down at the toilet. Various brown logs of shit sat on the toilet with Hancock's earrings sitting on top of the pile of shit.
"Well, looks like this is where we part ways, Hancock." Nami said, though she knew Hancock could no longer hear her. "At least you made me look better. And gave me this cool Devil Fruit.
It was ironic. Boa Hancock, the most beautiful woman in the world, was reduced to a pile of shit and fat on the Straw Hat's navigator.
Nami began to flush the toilet, though the amount of shit in the toilet meant she had to flush a few times, though eventually what remained of Hancock finally flushed down the toilet and into the sewers.
As Nami walked out of the bathroom, she continued to admire her body. "Well, looks like the reign of Boa Hancock as the most beautiful woman in the world has come to an end. The reign of Nami has begun." Nami thought to herself. "Now, what to do next..."
