Power and Denji are holed up in a cramped, dimly lit room, the air heavy with the scent of iron and sweat. Power, the Blood Fiend, her strawberry-blonde hair tousled and horns glinting, shoves Denji against the wall with a wild grin. "Oi, Denji, ready to get wrecked by the great Power?" she taunts, her voice dripping with narcissism. Denji, his Public Safety uniform half-unbuttoned, smirks, eyes gleaming with a mix of naivety and hunger. "Bring it, you loudmouth fiend," he shoots back, tugging at her tie.
Power wastes no time. She grabs Denji's shirt, ripping it open with a cackle, buttons scattering across the floor. "Weak human clothes!" she mocks, her hands clawing at his chest. She presses herself against him, lips crashing into his with a messy, toothy kiss, her tongue aggressive and unyielding. "Fuck, you taste like cheap ramen," she growls between kisses, but her hips grind against his, betraying her eagerness. Denji groans, hands gripping her waist, pulling her closer. "Better than your blood stink," he retorts, biting her lower lip. She laughs, a sharp "Gyahaha!" before shoving him onto a creaky bed in the corner.
Power straddles him, yanking off her own shirt, exposing her pale skin and small, firm breasts. "Look at these, Denji! Perfect, right?" she boasts, grabbing his hands and pressing them to her chest. "Squeeze harder!" she demands, moaning loudly as he complies, her voice echoing in the small space. Denji's eyes widen, his arousal evident as he kneads her flesh, thumbs brushing her nipples. "Shit, Power, you're loud," he mutters, but his hips buck up against her.
Power's blood powers activate, a thin red tendril forming from her fingertip, slithering down to wrap around Denji's hardening cock. "Feel that, you dumbass?" she moans, the tendril pulsing with warmth, stroking him in tight, rhythmic squeezes. Denji gasps, "Fuck, Power, what the—oh!" His words cut off as she leans down, licking a stripe up his neck, her moans vibrating against his skin. "So good, Denji! Keep up, you weakling!" she cries, hips rolling against his thigh, her arousal soaking through her pants. She tugs his pants down, freeing him, and the blood tendril morphs into a slick, warm sheath that envelops him completely. "Fuck, yes!" Power moans, her voice high and unrestrained as she works the blood-sheath, tightening and twisting in ways no human hand could. Denji's head falls back, a low "Ngh, shit!" escaping as he grips her thighs, fingers digging in.
Power's moans escalate, a constant stream of "Ah! Mmm! Oh, fuck!" as she rides his thigh, movements jerky and desperate. "More, Denji! Don't just lie there!" she snaps, eyes flashing with cross-shaped pupils. She shifts, positioning herself over him, and sinks down onto his cock, her blood powers enhancing the sensation, making her inner walls pulse like a heartbeat. "So fucking good!" she screams, moans bouncing off the walls as she rides him hard, hips slamming down with fiend strength. Denji groans, "Power, you're gonna break me!" but his hands guide her, pulling her down harder.
Power leans forward, horns grazing his forehead as she kisses him sloppily, moaning into his mouth. "You love this, don't you, Chainsaw Boy?" she teases, her voice breaking into a loud "Oh!" as she clenches around him. Her blood tendrils reappear, one wrapping around his balls, massaging gently, while another flicks against her own clit, amplifying her pleasure. "Fuck! Yes! Ngh!" she wails, body trembling as she chases her peak.
Denji flips her over, surprising her with his hybrid strength. "My turn, you noisy fiend," he growls, pinning her wrists above her head. He thrusts into her, deep and relentless, each movement drawing a new moan from Power— "Harder, you idiot! Oh!" Her legs wrap around his waist, pulling him closer, her blood powers creating a warm, vibrating ring around the base of his cock, driving him wild. "Shit, Power, that's—fuck!" he gasps, pace faltering as the sensation overwhelms him.
Power's moans grow louder, a chaotic mix of "Mmm! Fuck! Yes! Denji!" as she arches beneath him, body slick with sweat. She uses her blood to form soft, pulsating pads that press against her nipples, making her cry out even more. "I'm the best, ain't I?" she pants, voice smug despite the desperation. Denji grunts, "Yeah, yeah, keep talking," but his focus is on the way her body grips him, her blood-enhanced heat pushing him to the edge.
They switch again, Power shoving him onto his back and climbing onto his face. "Lick, human!" she orders, moaning loudly as his tongue meets her dripping core. "Fuck, yes! Right there!" she screams, grinding against his mouth, blood tendrils stroking him below to keep him hard. Her moans are relentless, filling the room— "Mmm! Oh! Don't stop, Denji!"—as she clutches his hair, thighs trembling. Denji groans into her, the vibrations making her wail louder, "Fucking perfect!"
She slides back down, impaling herself on him again, this time facing away, her ass bouncing as she rides him reverse. "Look at that, Denji!" she moans, using a blood tendril to spank herself lightly, the sharp sting making her clench tighter. Denji grips her hips, thrusting up to meet her, his groans mixing with her endless moans. "Power, you're—shit, too much!" he gasps, but he doesn't stop, driven by her vocal intensity.
Power spins around, facing him again, and leans down to bite his shoulder, teeth grazing without breaking skin. "You're mine, Denji!" she moans, her blood powers creating a pulsing, heated coil that wraps around their bodies, binding them together as she moves. Her moans peak— "Ah! Fuck! I'm—oh!"—as she comes, body shuddering, blood tendrils tightening around Denji to push him over the edge. He follows, groaning her name, his release mixing with her heat.
Power's not done. She pulls him up, pushing him against the wall again. "Again, Chainsaw Boy!" she demands, voice hoarse but still loud with moans. She wraps her legs around him, guiding him back inside, her blood forming a slick, vibrating layer that intensifies every thrust. "Oh! Yes! Fuck, Denji!" she screams, moans unending as they go again, her body insatiable. Denji matches her, his hybrid stamina keeping up, grunting, "You're crazy, Power!" but he's grinning, lost in the frenzy.
They collapse eventually, Power sprawled across Denji, still moaning softly— "Mmm, fuck, that was good"—her voice finally quieting. Denji pants, "You're gonna kill me one day." Power laughs, "Hah! You'd love it, dumbass."
