Serena's resistance had almost completely evaporated. Her hands, which once pushed him away, now clutched desperately at his shoulders and back, nails digging into his skin through his shirt.
Zane kept thrusting into her with deep, punishing strokes, the desk shaking beneath them. Papers continued to flutter to the floor unnoticed.
"You feel how tight you are around me?" he growled against her breast, biting lightly at the sensitive nipple. "Your body knows exactly what it wants, even if your mind is still fighting it."
Serena moaned brokenly, her hips meeting his thrusts eagerly now. "It's too much… too good… We shouldn't be doing this…"
The system chimed triumphantly in Zane's mind.
[Novice Power Pack Unlocked!]
[New Ability: Aura of Desire (Enhanced) – Focus on a single target for intensified, prolonged effect.]
[Seduction Dominion Level 1 Achieved. Taboo actions grant bonus power.]
A rush of new energy surged through Zane. His movements became more confident, more skilled, as if the system was directly enhancing his technique. Every thrust hit deeper, angled perfectly to rub against her most sensitive spots.
He kissed her deeply for the first time, tongue invading her mouth in a possessive claim. Serena kissed him back with desperate hunger, years of emotional repression and the system's influence turning her into a trembling, needy mess.
When they finally broke apart for air, saliva connecting their lips, she whispered shakily, "What if the twins come home early? What if someone hears us?"
Zane smirked darkly, never slowing his pace. "Then they'll hear how their mother moans like a whore when her stepson fucks her senseless on her own desk."
The filthy, degrading words sent a visible shock of pleasure through Serena. Her inner walls clenched hard around him, another orgasm building rapidly.
Zane gripped her thighs, spreading her wider as he pounded into her with increasing force. "Come again for me, Stepmother. Let go completely. Show me how much you've needed this."
Serena's eyes rolled back. Her entire body tensed like a bowstring.
Then she came with a raw, unrestrained scream, her juices gushing around his cock as powerful spasms milked him.
The intensity pushed Zane over the edge. With a guttural groan, he buried himself as deep as possible and erupted inside her, flooding her womb with thick, hot spurts of his cum.
They stayed locked together for long moments, both panting heavily, sweat glistening on their skin.
Serena looked up at him with wide, dazed eyes—shock, shame, lingering ecstasy, and something dangerously close to addiction all mixed together.
"What… what have we done?" she whispered hoarsely, her voice barely audible.
Zane remained buried inside her, still semi-hard. He brushed a strand of hair from her face almost tenderly, though his smile was pure darkness.
"Only the beginning, Stepmother. And you're going to crave it again before the night is over."
