[* 3rd Person POV *]
"See?" Tsunade murmured, the thin smile never leaving her lips as she watched the fresh puddle form and the first small chakra-slug continue its slow, deliberate path toward the still-spasming, dripping entrance.
"You came just from imagining it. Imagine how hard you'll cum when they actually start."
The lead slug did not stop.
Its soft, translucent body pulsed once more against the soaked, oversensitive folds, tasting the fresh wetness that still leaked from the fake's earlier climax, then began to push forward with slow, inexorable, almost curious purpose.
The cool, slightly sticky tip of the chakra-creation pressed firmly against the twitching, flushed entrance. Robin's breath caught in a sharp, broken hitch that turned into a high, involuntary whimper. Her golden eyes went wide, pupils blown. Every muscle in her thick thighs tensed hard as the living, slimy weight started to sink inside her millimeter by millimeter.
The penetration was nothing like a finger or a cock or anything else she had ever taken.
The slug's body was cool where her cunt burned hot, flexible and yielding yet persistent, coated in that luminous, chakra-slick mucus that made every single millimeter of entry feel exaggerated, slippery, and completely inescapable.
It stretched her gently but with relentless insistence, the soft, pulsing mass molding itself perfectly to the shape of her inner walls as it slid deeper and deeper. The sensation was alien and overwhelming cool living weight moving of its own will, leaving a thick, glowing trail of slime that made every tiny shift and pulse feel slicker, wetter, and more intense than the last.
The mucus seemed to tingle faintly with residual chakra, heightening every nerve it touched until the simple act of being entered by something so small and soft became almost unbearable.
Robin's mind fractured under the dual assault of physical sensation and pure, relentless masochistic self-awareness. Thoughts tumbled over one another in a frantic, shameful spiral that only made her clench harder around the intruding creature.
I'm letting a slug a chakra slug made from the real Tsunade's will crawl inside me… she's watching me take it with that cold little smile… I just came from imagining this exact moment and now it's actually happening… I'm so pathetic… my cunt is clenching and fluttering around a slimy little creature like it's the best thing I've ever felt in my life…
I love how cold and wet and alive it feels… it's pulsing against places nothing else has ever reached… the slime is so thick and glowing and it's coating every wall… I'm going to cum again just from how disgusting and perfect and humiliating this is… the real Hokage is using her summons to fuck the body I stole and I'm dripping all over them like a broken toy…
A long, broken, almost sobbing moan tore from her throat as the slug worked itself fully inside, its entire soft, translucent body now buried deep in the fluttering, overheated clutch of her cunt. The cool, slimy weight shifted and pulsed once it was seated, exploring the velvet heat with slow, living curiosity, and every tiny undulation sent fresh, electric sparks of overwhelming sensation racing through her overstimulated nerves.
Clear fluid continued to leak around the intrusion in steady, glistening drips that mixed with the luminous mucus and ran down the cleft of her ass onto the debris below. Her massive breasts heaved and swayed with every shaky, uneven breath. Her hips gave small, helpless, involuntary little twitches as if her body itself was trying to take the living thing even deeper, to feel more of that cool, pulsing, slimy fullness.
Tsunade watched the entire process with open, growing delight. The thin smile on her lips had sharpened into something colder and far more interested. She withdrew her fingers slowly from the fake's cunt, letting the stolen body feel the sudden, brief emptiness for a single heartbeat before the slug's soft mass filled the space again completely.
Then she simply leaned back on one knee amid the rubble, resting her weight casually, and observed the show with the focused attention of someone studying a particularly fascinating specimen.
"Look at you," she said softly, almost conversationally. "Taking a chakra slug like it's the only thing you've ever wanted. Your whole body is shaking. You're still dripping. And that was only the first one."
With a small, almost lazy gesture of her hand she signaled the rest of the cluster.
More of the small chakra-slugs began to move with renewed, purposeful energy, crawling up the trembling, slime-streaked thighs toward the same soaked, already-occupied entrance. Their soft bodies left glowing trails across the pale skin.
One reached the stretched, glistening rim and began to press insistently alongside the first, its cool tip nosing at the sensitive folds that were already stretched around its companion. Another followed close behind, then a third, the cool, slimy bodies crowding against the oversensitive entrance, seeking entry with patient, living determination.
Their luminous mucus mixed freely with the fake's own clear fluids until everything between her spread legs glistened and shone under the dim light filtering through the gaps in the ruined roof, a wet, glowing mess of arousal and chakra.
Robin's voice broke into frantic, high, overlapping sounds half coherent protest, half raw desperate pleasure as the second slug started to force its way inside alongside the first. The stretch increased immediately, the cool living weight doubling, the slime making every incremental push feel exaggerated and inescapable. Her inner walls fluttered and clenched in helpless rhythm around both soft bodies. Fresh fluid sprayed in smaller, involuntary spurts around the dual intrusion.
Two of them… two slimy chakra creatures stretching me open while she watches… I'm so full of cold living slime and it feels so wrong and so good… my brain is melting… I can't stop clenching… I don't want them to stop… I'm a stolen body being used by the real owner's summons and I'm going to cum again just from how full and disgusting and perfect it feels…
"Please—they're—ahh—too much—I can't—there's another one—!"
She managed between broken gasps, even as her hips twitched upward to meet the invading creatures rather than pull away.
Tsunade only chuckled low in her throat, the sound rich with cold amusement, and made another small gesture. More of the cluster answered, crawling higher, pressing closer, determined to join the first two inside the wet, trembling heat of the body that had dared to wear her face.
She settled in to watch how many the soft, greedy, stolen cunt could take before its owner broke completely again, golden eyes gleaming with newly awakened sadistic interest as the third slug began to push for entry and Robin's moans climbed higher and higher into pure, overwhelmed noise.
