Jenna smirked triumphantly, satisfied by the obvious signs of desire pouring forth from Shiro Taiyo. Their body language, their breathing, the unmistakable sound of their cock pulsing in sync with hers - everything screamed consent. Releasing her hold on Shiro's hair, she slowly started undoing her tight yoga pants, revealing more of her voluptuous curves. As soon as her thick member was fully exposed, she moved in again, positioning herself between Shiro's legs."Tell me how much you want this," she demanded, her blue eyes filled with hunger. "Tell me you've been imagining your perfect futa older sister taking your virginity, making you beg for more while your tight hole surrenders to my huge cock."

Delighted by Shiro's visible struggle, Jenna relished every moment of power she had over them. She placed a gentle kiss on top of Shiro's head before whispering softly into their ear."That's right, baby boy. You belong to me now. Your cute little ass belongs to me, and I plan on claiming it thoroughly today," she murmured seductively. "So tell me… Are you ready?" Without waiting for an answer, Jenna quickly thrust forward, pushing half of her massive girth inside of Shiro's tight entrance. A loud moan escaped both of their lips as pleasure coursed through their bodies; Shiro's hands grasped onto the walls behind them for support, their hips instinctively lifting upwards to accommodate each powerful thrust. The sounds of flesh slapping against wetness echoed throughout the empty house, filling the air with erotic rhythm.

Jenna chuckled darkly, delighted by Shiro's pleading voice. Her pace quickened even further, slamming her entire length into Shiro's tight ass with forceful precision. Each brutal thrust caused waves of ecstasy to reverberate through both of them, intensifying the already mind-bending orgasmic experience."Because I bloody well wanted it that way, kitten," she growled playfully. "And besides, who else would satisfy someone like you? Some pathetic human male? No thanks!" Reaching down, she grabbed Shiro's own hardening member, expertly stroking it in time with her thrusts. Soon enough, Shiro's moans turned into high pitched whimpers, their climax rapidly approaching. With a final, deep groan, Jenna let loose a torrent of hot seed, painting Shiro's insides with her creamy load. Panting heavily, she pulled out slowly, savoring the sight of her thick cum oozing out of Shiro's stretched hole. "Now then," she said, licking her lips clean. "How do you feel about some post-fuck fun, hmm?"

Intrigued by Shiro's desperate words, Jenna couldn't help but grin devilishly. Approaching Shiro's still trembling body, she wrapped her strong arms around them, trapping them in her vice-like embrace. Slowly, methodically, she started massaging Shiro's swollen member, teasing the sensitive tip with light touches before increasing pressure until sharp gasps of pure pleasure were forced out of Shiro's throat."Oh, don't worry, darling," she purred. "You'll get everything you want and more." With practiced ease, Jenna positioned Shiro's rigid erection at the perfect angle before lowering herself onto it, engulfing the head of Shiro's cock in one swift motion. Their moans intertwined, creating an unholy symphony of desire and submission. As their hips rocked back and forth, driving themselves closer to completion, Jenna leaned in close, her breath brushing against Shiro's flushed cheek. "Tell me," she whispered huskily. "Do you wish for me to suckle your delicious cum from this beautiful cock, or shall I ride you till we both collapse in bliss?"

Chuckling deeply, Jenna relished in Shiro's helplessness. She loved how much control she had over them, how Shiro was willing to surrender completely to her every whim. Standing up straight again, she reached behind her and gently caressed Sh's ass cheeks, eliciting another soft moan from their lips. Then, without warning, she bent forward and reinserted half of her massive cock into Shiro's tight rear entrance."A little bit of both, perhaps?" she mused aloud, her eyes twinkling with mischief. With slow deliberate movements, Jenna began to pump her huge member in and out of Shiro's ass, each powerful thrust causing Shiro's stomach to contract violently as their cocks rubbed together in synchronized rhythm. The sounds of flesh slapping against wet skin echoed throughout the room, punctuated by Shiro's cries of ecstatic agony. As they continued their depraved dance, Jenna increased the speed and intensity of her thrusts, pushing Shiro harder against the wall until there was nothing left between them except primal animalistic hunger. A thin layer of sweat formed on both of their bodies, mixing together in a sickeningly erotic display of power and dominance. Finally, unable to hold back any longer,

Growling low in her throat, Jenna picked up pace even further, her thick cock almost disappearing entirely inside Shiro's tight hole. With a loud groan that reverberated through the room, she orgasm hit hard, sending waves upon waves of hot sticky seed shooting out of her massive cockhead and spraying everywhere. Shiro felt their own orgasm building up within them, matching the ferocity of Jenna's release.Holding onto Shiro's wrists firmly, Jenna leaned down and captured their mouth in a rough, bruising kiss, tongue forcefully probing deep inside their mouth while her ballsack smashed against Shiro's ass cheeks, leaving behind a trail of semen and sweat. Breathless and spent, she finally pulled away, resting her chest against Shiro's sweaty back. "That… was… incredible…" panting heavily, tears forming in the corners of Shiro's eyes from the intense sensations.
