She told me to stop. Her voice was sharp, that same bossy tone she used when she first married my dad two years ago. But I had her pinned against the kitchen counter, my hands already yanking her silk robe open so her heavy tits spilled out. Her nipples were hard as rocks. She wasn't wearing anything underneath.
"Get off me, you little shit," she hissed, pushing at my chest. "Your father could walk in any second."
I didn't answer. I just shoved my knee between her thighs and forced them apart. She was already wet. I could smell it. My fingers found her cunt and shoved two inside without warning. She gasped, her hips jerking back, but she was dripping down my knuckles. "Fuck you," she spat, but her pussy clenched around my fingers like it wanted more.
I pulled my cock out, thick and angry, and forced it between her legs. She tried to close them but I was stronger. One hard thrust and I was buried to the balls in my stepmom's tight, hot cunt. She cried out, half protest, half moan, her nails digging into my arms. "No—don't—"
I fucked her hard right there, the counter digging into her ass with every slam. Her tits bounced with every thrust. She kept saying no but her pussy was sucking me in, soaking my shaft, making filthy wet sounds every time I bottomed out. I grabbed her hair and yanked her head back so I could bite her neck while I pounded her.
"You wanted this," I growled against her ear. "Walking around in those tiny robes, bending over in front of me. Now take it."
She came with a strangled sound, her whole body shaking, cunt pulsing around my cock like it was trying to milk me dry. I didn't stop. I flipped her around, bent her over the counter, and drove back in from behind. Her ass cheeks spread wide around my shaft. I slapped one hard and she yelped, but her hips pushed back to meet me.
I reached under and rubbed her clit fast and rough until she came again, legs trembling, cursing my name.

Only then did I let go, flooding her married pussy with thick ropes of cum. It leaked out around my cock as I kept thrusting through it, making sure every drop stayed deep.
She stayed bent over, breathing hard, robe twisted around her waist. When I finally pulled out, my cum ran down her thighs. She didn't move. Didn't tell me to stop again. She just looked back at me with dark, furious eyes and whispered, "Lock the fucking door next time."
I already had plans for the bedroom.
