[* 3rd Person POV *]
The real Kuma stood over the collapsed form of Nico Robin for only a moment longer.
The street still smelled of sweat, metal, and the thick, wet aftermath of prolonged use. Fluid leaked steadily from between her thighs, soaking into the dirt in a widening dark patch.
Her body twitched in residual spasms. Her eyes were half lidded, unfocused, lips parted around shallow breaths.
Kuma's voice remained flat.
"Primary objective complete. Straw Hat crew neutralized and dispersed. This unit's secondary function is no longer required"
He turned away without another glance at the archaeologist.
The Pacifista that had been inside her straightened its clothing, the massive metallic cock retracting with a soft mechanical sound until it vanished beneath the fabric.
Both figures began to move off down the ruined street, leaving the mess behind them as if it were no more significant than any other operational detail.
Sentomaru remained.
He looked down at Robin for several long seconds. The scar that ran from his left eye to the corner of his mouth pulled slightly as his expression shifted into something between evaluation and mild irritation.
His huge frame blocked most of the light that filtered through the broken canopy of the grove. The red and white rope around his midsection shifted as he crossed his thick arms.
"Messy"
He repeated, voice low and rough.
"Clones don't know restraint when the limits come off. Look at this. Street's a damn puddle. Body's still twitching. Pussy still open and dripping like it hasn't figured out the session's over"
He crouched, the movement surprisingly controlled for a man of his bulk.
One massive hand reached out and gripped Robin's hip, turning her onto her back with casual strength.
Her heavy breasts shifted and settled. Clear fluid and thicker white streaks glistened between her spread thighs.
The entrance to her cunt remained visibly stretched, the outer lips puffy and shiny.
Sentomaru studied it the way he might study a training dummy after a heavy session.
"Still accepting shape. Internal walls haven't closed all the way. Pressure readings would still be high if I bothered measuring"
He glanced up at her face.
"You hearing me, criminal? Or is the brain still offline from getting fucked stupid by a machine?"
Robin's eyes focused slowly. Her voice came out hoarse, raw from screaming earlier.
"I… hear you…"
"Good"
Sentomaru stood again, towering. He reached down, hooked both hands under her arms, and lifted her off the ground as if she weighed nothing. Her feet dangled.
Fluid continued to drip from her in a thin string. He carried her three steps and set her down on her knees in front of him, facing the large bulge that had begun to press against the front of his pants.
"I'm not going to pretend this is about duty"
He said, already working the fastenings.
"I'm also not going to claim I'm only doing this because the opportunity is here. I'm doing it because I want to. That's all the reason required"
The thick, heavy cock that emerged was proportional to the rest of him darker, veined, the head already wet.
It was not metallic, but it was solid, weighty, and already fully hard. Sentomaru wrapped one large hand around the base and angled it toward Robin's mouth.
"Open. You've already taken metal the size of a forearm. This shouldn't be a problem. And if it is, I don't care"
Robin's lips parted.
He pushed forward without waiting for further invitation.
The broad head forced past her teeth, stretching her jaw. He kept going until the head pressed against the back of her throat. Robin gagged, throat convulsing around the intrusion.
Saliva spilled from the corners of her mouth.
Sentomaru exhaled through his nose.
"Tight. Hot. Wet. Better than the clone's readings suggested"
He held her head in place with both hands and began to thrust in short, controlled strokes, each one seating a little more of his length.
"I'm not going to talk about how good this feels. I'm just going to use the hole. That's all"
He continued anyway.
"Throat's gripping every ridge. You can feel the shape already. Swallow around it. Don't pretend you don't know how"
Robin's hands came up to rest against his thick thighs. She did not push away.
Her eyes watered. Each time he pushed deeper she made a choked, wet sound. Spit ran down her chin and onto her bare breasts.
Sentomaru pulled back far enough for her to drag in a ragged breath, then pushed in again, deeper this time.
The bulge of his cock appeared briefly in the front of her throat. He held there for several seconds, watching her struggle, then withdrew completely.
A thick string of saliva connected her lower lip to the head of his cock.
"Mouth works. Now the rest"
He lifted her again, turned her, and set her on all fours in the same dirt the Pacifista had already used.
Her massive ass was still marked from earlier impacts. Fluid continued to leak from her cunt in a slow, steady trickle.
Sentomaru knelt behind her, one hand spreading one cheek while the other guided his cock to the entrance.
He pushed in with one continuous thrust.
The stretch forced a broken sound from Robin's throat. Her arms nearly buckled. Sentomaru did not stop until his hips were flush against her ass and the full length was buried.
He stayed there for a moment, grinding in small circles.
"Still tight after all that. Impressive. Or just desperate."
He began to move long, heavy strokes that dragged almost all the way out before slamming back in.
The wet sound of each impact was loud in the quiet street.
"I'm not going to claim this is anything other than what it is. You're a warm, wet set of holes that happens to belong to a high value criminal. I'm going to use them until I'm finished. That's the entire plan"
He kept talking anyway, voice steady even as his pace increased.
"Ass is soft. Takes the impact well. Cunt is still trying to close around the shaft on every withdrawal. You can feel how much shape you've already accepted. Look down if you want. Watch your own stomach move when I bottom out"
