Yuka moaned loudly, her voice raw with desperation.
“Fuck! This is insane! I can’t stop moving!”
She bounced her ass up and down on his thighs, slamming his cock deep into her tight pussy with every thrust.
“Ungh, you feel so good,” she grunted, grabbing his wrists with one strong hand and pinning them above his head. Her other hand roamed his chest, squeezing his muscles roughly.
“Feed my pussy with your huge cock, you little slut,” she demanded, her hips grinding harder. “I’m going to make you pump my pussy full of cum and knock me up.”
“Yuka, slow down! Aghh!” William whimpered, his body arching under her weight. But Yuka didn’t let up. She rutted against him like a wild beast, the sharp slaps of skin on skin mixing with their heavy moans and gasps, filling the dark bedroom.
“You like that, Cuz? You like me fucking your big, hard cock?” Yuka growled into his ear, her eyes glazed with lust. “Beg to cum inside me. Beg me! Fill me with your cum, breed me!”
“Uh, f-fuck!” William gasped. The pleasure overwhelmed him as Yuka essentially raped him, her aggression making any past encounters seem mild. Being pinned and fucked by a woman was a shocking thrill, and her superior strength left him helpless.
Her thrusts were brutal and erratic, focused on milking his cum rather than mutual pleasure. But she was lost in it, and so was he. Despite his ego-driven protests, his hips bucked up to meet hers, the wet smacks of their joining growing louder in the shadowy room.
“I’m… close,” William panted, his balls drawing tight, a hot tingle spreading from his spine. He drove his cock upward faster, pounding into his cousin as Yuka bounced wildly, shaking the bed frame with each impact.
“Uuurhhh, yesss! Fill my pussy! Come on, come onnnn, Will! Oooohhh, fuck!”
“Heeeere it comes!” With a deep roar, William erupted, his cock pulsing as he flooded her womb with thick ropes of cum. Spurt after spurt shot from his tip, coating her insides with his hot seed.
Yuka screamed in ecstasy, her pussy clamping down like a fist around him as her own orgasm hit. She felt the scorching jets blasting into her core, her head thrashing side to side.
The sensation of his semen filling her fertile cunt pushed her over the edge, her walls convulsing wildly. This wasn’t her first time, but nothing had ever felt this intense—his load triggered waves of bliss that made her body shudder uncontrollably.
Just as the peak of her climax washed over her, a sudden presence registered behind her. Her keen senses had failed amid the overwhelming pleasure. Before she could turn, a slender arm wrapped around her neck, squeezing tight. Air cut off, her vision blurred as the chokehold tightened.
William, still riding his high, moaned softly, his cock twitching with the final spurts inside her gripping heat. He didn’t notice the intruder until Yuka’s body suddenly went slack against him. Her head fell back, eyes rolling white, collapsing like a lifeless weight.
“Hey? Yuka? You okay? Hey!”
Panic surged through William as he wrapped his arms around her, shaking her shoulders to rouse her. But before he could react further, a thin arm lashed out from the darkness, seizing Yuka’s shoulder with iron strength and shoving her aside.
Her unconscious form tumbled off the bed, hitting the floor with a heavy thud. She lay sprawled there, naked and drained, a sticky trail of their combined juices oozing from her swollen pussy lips.
“Will? Seriously?”
The voice cut through the air, sharp and accusatory.
William spun around, his cock still semi-erect and glistening with their fluids, heart pounding. In the faint light, Celestina stood glaring at him—his younger sister. Her reptilian eyes gleamed like black gems, slitted pupils narrowed in rage.
She was stark naked, her lithe body covered in faint, iridescent scales that shimmered along her shoulders, ribs, and the length of her whipping tail. The scales accentuated her fierce beauty, drawing the eye to the subtle swell of her breasts and the curve of her hips.
“Tina?” William stammered, shock freezing him in place. “Shit, you scared the hell out of me.”
Celestina hissed low, her tail lashing as she crossed her arms under her chest, pushing her small tits up slightly. Her gaze darted to Yuka’s limp body on the floor, then back to him, burning with betrayal and fury.
“Care to explain what the fuck is going on here, Will?”
William winced under her grip, the sharp sting of her nails piercing his skin. “Sorry, sis. Did we wake you? I didn’t mean to.”
Celestina’s slitted eyes blazed with a mix of fury and hurt, her tail whipping sharply against the bedframe. She lunged forward, slamming her palm against his shoulder to shove him back onto the mattress.
Her lithe body loomed over him, the warmth from her scaled skin seeping into his chest as she straddled his hips, pinning him in place.
“Do you think that’s the fucking problem? You’re balls-deep in our cousin, in my bed, and you ask if you woke me?” she snarled, her voice a low hiss that vibrated through her throat.
“I’m not blind, Will. Or stupid. I saw exactly what you two were doing. And as much as I want to drag her scaly ass out by the hair right now, looking at you… She’s not the only one at fault here.”
William let out a dry chuckle, aiming to lighten the mood, but it sounded forced and awkward in the tense air.
“Yeah, about that… I actually came in here for you. Somehow, I mistook her for you in the dark. Didn’t know Yuka was crashing here tonight. One thing led to another, and… well, you saw how it ended.”
He shifted beneath her weight, his semi-hard cock sliding against the smooth inner curve of her thigh, still coated in Yuka’s slick juices. The contact sent a jolt through him, and he felt himself twitch against her.
Celestina stared down at him, her mouth parting in shock before snapping shut, then opening again as if words failed her.
“You mistook her for me? Are you fucking serious right now?”
The sharpness in her tone cracked, revealing a thread of disbelief laced with reluctant amusement that left William unsure if she wanted to slap him or laugh.
“…Yeah,” William replied, shrugging as if it were a minor mix-up, though his gut twisted with the weight of it. “I really didn’t know she was here. The room was pitch black, and… shit, she felt just like you at first.”
“God, Will! Can’t you be more cautious? If I didn’t know you better, I’d think she jumped you. Hell, I’d have ripped her throat out for it already.”
Her voice broke on the last word, raw anger seeping through, mingled with something deeper—possessiveness, maybe fear.
She glanced over her shoulder at Yuka, who stirred faintly on the floor, a soft groan escaping her lips as her legs kicked weakly, her pussy still leaking their mingled cum onto the carpet.
“She looked like she was straight-up assaulting you,” Celestina continued, her breath hitching. “I almost—fuck, for a second, I was ready to grab the lamp and bash her skull in! I thought some intruder had broken in and was raping you on my bed!”
“…Fortunately, you didn’t,” William said, forcing a grin despite the chaos. “I don’t want to be an accomplice to murder.”
“I was this close,” she hissed, leaning in until her hot breath fanned across his face, her sharp teeth glinting in the dim light. “And that bitch! She could’ve sensed I was awake with those freak senses of hers, but she was too busy slamming her cunt down on your cock to notice me lurking.”
“Sorry about that…” William murmured, his eyes softening as he watched her tail coil tightly around the bedpost, betraying her agitation.
Celestina hissed again, but the sound softened into a frustrated exhale, her rigid posture easing just a fraction. Her brows furrowed deeply, lips pressed into a tight line that made her look both vulnerable and fierce.
Unable to resist, William reached up, his hand cupping one of her small, firm tits. The flesh was warm and yielding, but the faint scales along the underside added a gritty, textured friction against his palm—rough like fine sandpaper, yet thrillingly unique.
Celestina shot him a glare, her reptilian eyes narrowing to slits, but she didn’t yank away. Instead, her nipple stiffened instantly under his touch, peaking into a hard nub that strained against his fingers, begging for more.
“I’m not joking, Will,” she warned, her voice steadying into a scold. “I told you before to be careful with women, especially mutants like us. We can lose control if we’re stimulated too much—pheromones, heat, all that shit. She could’ve really hurt you… H-hey, I said, li-listen!”
“…I know, Tina. Don’t worry, I’m listening~” William’s grin turned playful, his tone dropping to a husky tease as he ignored her protest.
He leaned up slightly, his breath warm against her ear, while his hand kneaded her breast more insistently, fingers digging into the soft mound until she arched her back, pressing into him despite herself.
“I’m still… haaah, talking, Will… stop that…” Celestina’s words came out breathy and fractured, her eyes fluttering half-shut as a shiver ran down her spine. Her chest heaved faster, shoving her tit deeper into his grasp, and a subtle flush bloomed across her scaled cheeks, heating the air between them.
William chuckled low, his free hand gliding up her arm, fingertips tracing the subtle ridges of scales along her bicep—each one slightly raised, like embedded jewels that prickled erotically against his skin.
“You’re saying stop, but your body’s screaming for more. You love it when I touch you like this, don’t you? All those little scales are getting you worked up.”
He rolled her nipple between his thumb and forefinger, pinching just hard enough to elicit a sharp gasp from her parted lips, her tail flicking erratically behind her.
“Will, damn it… I’m serious,” she squirmed atop him, but the movement was languid, her hips grinding down instinctively so her slick folds brushed his thigh. “You snuck in here, fucked Yuka thinking it was me, and now you’re groping my tits as if nothing happened? We need to talk about this—!”
“Oh, I’m all ears,” he whispered, his mouth trailing to her neck.
His lips ghosted over the sensitive juncture where smooth skin met the edge of her scales, then he nipped the spot sharply before sucking hard, drawing a faint red mark that contrasted with her iridescent hide.
His hand on her breast drifted lower, palm skimming the textured line of her ribcage, feeling the subtle give of muscle beneath.
Celestina’s fists clenched the sheets on either side of his head, knuckles whitening, but she didn’t push him away. Her thighs squeezed his sides, a telltale rub of her pussy against his leg betraying the growing wetness there.
“You’re impossible… haa, just listen to me for once.”
Her scolding trembled with underlying worry, but her nipple pulsed under his teasing fingers, and she bit down on her lower lip to muffle a rising moan, her tail curling possessively around his calf.
“But… is she alright? You choked her out pretty hard there.” William’s voice softened with genuine concern, even as his thumb circled her areola, tracing the pebbled texture.
Celestina’s glare intensified for a beat, but her shoulders sagged, the tension ebbing as jealousy flickered in her eyes.
“I’m not a savage! I just… squeezed her windpipe until she blacked out. She’s tough—mutant like us. She’ll wake up with a raw throat and a hell of a headache, that’s all. Better than dragging her out and beating her senseless, which is what she deserves right now.”
Bitterness edged her words, thick with envy she couldn’t fully mask, her gaze flicking back to Yuka’s stirring form.
“Ugh, well, sorry about that. It’s my fault, really.”
William’s hand on her tit squeezed gently, drawing her torso down until her breasts pressed against his chest, the scales scraping deliciously over his skin. He slid his other hand up her side, fingers following the curving pattern of scales along her ribcage, dipping into the dips and feeling her shiver.
“Yeah, it’s yours… haah,” Celestina sighed warmly, her resistance crumbling as his touch ignited sparks along her nerves. Her hips rocked forward involuntarily, her wet pussy lips parting to glide along the length of his thickening cock, coating him in her arousal.
William drew Celestina closer, wrapping his arms around her lithe frame in a tight hug. His hands roamed down the smooth expanse of her back, fingers tracing the subtle ridges of scales that ran parallel to her spine before settling on the firm globes of her ass. He squeezed the taut muscles, feeling the heat radiating from her skin, the way her flesh yielded just enough under his grip to reveal the coiled strength beneath—like gripping a predator’s haunches, ready to pounce.
Celestina let out a deep, shuddering sigh, pressing her face into the crook of his shoulder.
She inhaled sharply, drawing in the heady mix of scents: the sharp tang of sweat from his recent fuck with Yuka, the musky remnants of cum still clinging to his skin, all layered over that intoxicating, familiar aroma that was purely William—earthy, masculine, and addictive. Her tail responded on instinct, snaking around his thigh and coiling tight, the sensitive tip stroking his calf in a possessive caress that sent a shiver up his leg.
“You’re such an asshole sometimes, you know that?” she murmured against his neck, her breath hot and uneven, fangs grazing his skin lightly.
William just grinned, his lips curving against her hair, unrepentant and smug.
Staring up at him, Celestina could see he wasn’t truly listening—not to her scolding, anyway. Even if the words registered, they bounced right off his thick skull without a hint of remorse.
What the hell had happened to her brother? How did he turn into this insatiable pervert, always chasing the next thrill without a care for the fallout?
“…You’re lucky I love you,” she added softly, the admission slipping out despite her frustration, her claws digging lightly into his back.
Of course, William knew it all too well. And he had no qualms about exploiting that vulnerability, turning it to his favor with ease.
“Yeah, I know. Luckiest bastard alive,” he muttered, his voice a low rumble as he pressed a kiss to the crown of her head, tongue flicking out to taste the faint salt on her scalp, mingled with the subtle, exotic spice of her scales.
Then he tilted her chin up with a gentle but insistent finger, forcing their gazes to lock.
Her reptilian eyes, slitted and stormy with lingering jealousy, met his—steady, playful, ignited by that ever-present spark of mischief that made her pulse quicken despite herself.
“Don’t think you can flirt your way out of this,” she warned, her free hand rising to pinch his cheek hard, twisting the skin until he winced and let out a hiss of mock pain.
“You know I’m pissed. If you snuck in here for me, then fuck me… not her. Not our damn cousin sprawled out like a used rag on the floor.”
She looked so adorably displeased in that moment, her full lips pursed into a pout that stripped away years, revealing the vulnerable girl beneath the fierce mutant exterior—raw, exposed, and aching for reassurance.
“…I’ll remember that next time,” William promised, though the glint in his eye suggested he might ‘forget’ just to rile her up again.
Before she could retort, he swiveled his head and captured her mouth in a tender kiss, lips pressing slowly and deliberately against hers.
Celestina feigned resistance, her palms shoving weakly at his chest, nails scraping over his nipples in a half-hearted protest. But it was all show—her body melted into him, arching forward as his tongue parted her lips and delved inside, stroking her own with lazy, teasing swirls that tasted of salt and lingering desire.
“You bastard,” she whispered when they broke apart, her voice dropping to a husky rasp, the sharp edge of anger twisting seamlessly into molten want. Her hips ground down against his, feeling his cock harden fully beneath her, pressing insistently against her slick folds as her arousal began to drip onto him.
