Naruto's mind blurred with heat.
Karin's pussy was already wrapped around him — slick, tight, and hotter than fire. Her body trembled as she slid down fully, her inner walls hugging his cock like a velvet trap.
"Fuck—fuckfuckfuck—I missed this," she gasped, grinding her hips in sharp, greedy circles. "You don't know what it's like, Naruto. Having tasted your chakra and then losing it—"
She bounced.
Hard.
His cock slammed upward, forcing guttural groans from his throat.
"K-Karin—too much—"
Her hands pressed to his chest, fingers digging into his skin.
"Shut up. You don't get to speak. You owe me."
Her glasses fogged as she rolled her hips, head tilting back in pure ecstasy.
From the spring's edge, the others watched.
Hinata bit her lip, eyes glued to the way Naruto's cock disappeared inside Karin's dripping cunt.
Sasuko growled. "She's using him like a chakra battery."
Tsunade, arms folded, nodded slowly. "And he's letting her."
But none of them moved.
Not yet.
Not while Karin claimed her fix.
Karin's riding turned frantic.
Her pussy clenched with every thrust — pulling chakra from his cock like it was feeding her, draining every pulse.
"Oh fuck—yes—your chakra—your cum—it's so rich, it tastes like lightning—!"
Her nails raked his chest as she came hard, milking his shaft, squirting violently across his abs.
But she didn't stop.
Didn't lift off.
She stayed seated — grinding, riding, taking everything.
Naruto twitched beneath her, eyes rolling back.
His cock pulsed once—
Twice—
And then he exploded inside her.
Thick, hot seed flooded her.
Karin moaned like a drug addict high for the first time in years.
"YES—YES—GODS YES—FILL ME—DROWN ME—!"
She came again as his cum spilled out around his cock.
Still, she didn't rise.
"More," she whispered. "You're not empty yet."
Hinata stepped forward.
"No," she said softly. "He's fading."
Karin turned, eyes bloodshot, body soaked in sweat and cum.
"Then seal him," she snapped.
And just like that…
The rest of the harem nodded.
Tsunade's hands glowed with chakra.
She pressed a palm to Naruto's stomach.
A glowing red seal formed — circular, intricate, lust-woven.
A binding that would keep him hard, keep him sensitive, and prevent any full orgasm without harem permission.
Naruto gasped — and whimpered.
The collar flared.
The seal pulsed.
And his cock stayed rock hard, even as Karin finally slid off him, dripping with cum.
They weren't going to stop him from cumming.
They were going to control it.
Forever.
