Serena's resistance was visibly cracking. The Pleasure Echo continued its merciless work, sending waves of phantom pleasure that made her nipples throb and her core clench with need every few seconds.
She tried to push past him, but her back met the solid edge of the mahogany desk. "Zane… this has to stop. I don't know what game you're playing, but it ends now. I raised you—well, tolerated you—under this roof. This is beyond inappropriate."
Zane didn't retreat. Instead, he pressed forward until their bodies were almost flush. He could feel the heat radiating from her skin through her clothes. "You never raised me, Serena. You made sure I knew every single day that I was nothing but a burden. A reminder of a friendship you tolerated at best."
His words stung, but they also fueled the dark heat building inside her. The system's influence made every insult from the past twist into something perversely arousing.
He placed his hands on her waist, gripping the curve of her hips through the tight skirt. Serena gasped, her body jerking at the contact.
[Desire Feedback: +81%. Power Points: 8/10.]
"Feel that?" Zane whispered hotly against her neck. "Your body is betraying you. Your nipples are so hard I can see them through your blouse. And I bet if I checked right now, your panties would be soaked."
Serena's hands came up to push at his chest, but the push was weak, almost half-hearted. "Don't… talk like that. It's disgusting. You're my stepson, for God's sake."
Yet her voice cracked on the last words, and her hips twitched forward ever so slightly, seeking contact.
Zane slid one hand down, tracing the side of her thigh before slipping under the hem of her pencil skirt. His fingers brushed the smooth, warm skin, moving higher until they reached the edge of her lace panties.
They were drenched.
Serena whimpered, a sound she immediately tried to stifle. "Zane… please… don't do this…"
But her legs parted just a fraction, giving him easier access.
He rubbed her through the soaked fabric in slow, deliberate circles, pressing against her swollen clit. The Pleasure Echo amplified every sensation tenfold, making it feel like invisible tongues and fingers were teasing her simultaneously.
Serena's head fell back, exposing the elegant column of her throat. A low, needy moan escaped her despite her best efforts. "Ahh… this is wrong… so wrong…"
Zane leaned in and kissed the sensitive skin just below her ear, then trailed his lips down to her collarbone. "That's exactly why it feels so good, isn't it? The more forbidden it is, the wetter you get for me."
He increased the pressure of his fingers, rubbing faster. Serena's breathing turned into short, desperate pants. Her hands clutched the edge of the desk so tightly her knuckles whitened.
The system rewarded his boldness again.
[Pleasure Echo strengthened. Target arousal level: Very High. Taboo multiplier active.]
Zane slipped his fingers under the lace, finding her slick, hot folds. He stroked her entrance teasingly before pushing one finger inside her tight heat.
Serena cried out, her walls clenching around the intrusion. "Oh god… Zane!"
The sound of his name on her lips in such a broken, lustful way sent a surge of power through him. He added a second finger, pumping them slowly while his thumb circled her clit.
Serena's hips began to rock against his hand, chasing the pleasure even as shame burned in her eyes. "We can't… the twins could come home any minute… someone might hear…"
"Then you'll have to be quiet," Zane murmured, kissing her neck harder, sucking lightly to leave a faint mark. "Or maybe part of you wants them to know how their proud mother sounds when she's fingered by her stepson."
The filthy words pushed Serena closer to the edge. Her moans grew louder, less controlled. Her breasts heaved with every ragged breath, the buttons of her blouse straining.
Zane could feel her inner walls fluttering, tightening around his fingers as her orgasm built rapidly.
He leaned close to her ear and whispered, "Come for me, Stepmother. Come on your stepson's fingers like the needy, forbidden woman you are."
Serena's body tensed. Her eyes rolled back slightly.
Then she shattered with a choked cry, her orgasm crashing through her in powerful waves. Her juices coated his hand as she clenched and pulsed around his fingers.
She slumped against him, panting heavily, legs shaking.
Zane slowly withdrew his fingers, bringing them to his lips and tasting her essence while she watched with dazed, lust-filled eyes.
The conquest had truly begun.
