He gave me a moment to adjust before starting to move, his hips snapping forward as he f****d me hard and deep. The bed creaked beneath us, the headboard slamming against the wall with each powerful thrust.
"Oh god," I panted, wrapping my legs around his waist. "Yes, Jaxon! f**k me harder!"
He obliged, pounding into me with abandon. The room filled with the obscene sounds of our f*****g - the slap of skin on skin, our moans and cries of pleasure.
'Tell me you love your stepbrother's c**k,' he demanded, thrusting relentlessly, our voices loud and unrestrained.
'I love it,' I whimpered, nails raking his back, pulling him closer. 'Don't stop... f**k me like you own me.'
I could feel my orgasm building quickly, the coil inside me winding tighter and tighter. Jaxon reached between us and rubbed my c**t in tight circles, sending me hurtling over the edge.
"f**k, I'm coming!" I screamed, my p***y clenching around his c**k like a vice as wave after wave of pleasure crashed over me.
Jaxon followed soon after, burying himself deep inside me as he groaned out his release. I could feel his hot c*m filling me up, marking me as his.
We collapsed together in a sweaty tangle of limbs, both panting hard as we came down from our highs.
After our first intense round of f*****g, Jaxon pulled out of my quivering p***y and stood up, his c**k still hard and glistening with our mixed fluids. He looked down at me with a predatory gleam in his eye.
"Get on your hands and knees," he commanded. "I want to see that ass in the air."
I did as he said, my p***y clenching with anticipation as I got into position. The headboard dug into my ribs as I braced myself, presenting my ass to him like a b***h in heat. I could feel his eyes on my exposed p***y and asshole, and it made me squirm.
"God, your holes look so inviting like this," he said, giving my ass a sharp smack. "I'm going to wreck you, sis. Pound you into the f*****g mattress until you can't walk straight."
I whimpered in both fear and excitement, my p***y gushing at his crude words. He grabbed my hips and aligned his c**k with my entrance, teasing me by rubbing the head up and down my slit.
Then he slammed inside me, not bothering to go slow this time. I cried out at the sudden intrusion, my back arching as he started to pound into me mercilessly. The new angle allowed him to go even deeper, hitting spots inside me that made me see stars.
"f**k, yes," he groaned, his fingers digging into my hips hard enough to leave bruises. "Take it, Lily. Take your stepbrother's cock."
My t**s bounced with each powerful thrust, slapping together obscenely. Drool ran down my chin as I panted and moaned, the pleasure overwhelming. He reached around and grabbed my hair, yanking my head back as he f****d me from behind.
"That's it," he panted. "Scream for me. Let the whole f*****g house know who's giving it to you."
I let out a loud wail, too far gone to care about who might hear us. All that mattered was the feeling of Jaxon's thick c**k splitting me open, wrecking my tight little cunt.
He pulled out suddenly, flipping me over onto my back. He pushed my knees up towards my shoulders, folding me nearly in half as he lined himself up with my asshole.
"Wait," I gasped, tensing up. "Not there. Please, Jaxon. I've never... I'm not ready."
He paused, looking down at me with a wicked grin. "Aww, poor baby. Think I'm gonna let you off easy? Not a chance, sis."
Before I could protest further, he pressed the head of his c**k against my tight puckered hole and started to push inside. The burning stretch was unlike anything I'd ever felt before as he forced his way into my virgin ass.
"Jaxon!" I shrieked, my fingers scrabbling at the sheets. "It hurts! You're too big!"
He didn't stop, gradually pushing more and more of his huge c**k into my clenching hole. "Relax," he grunted through clenched teeth. "Just breathe through it. You'll take it like a good girl."
I tried to do as he said, taking deep breaths as he continued to invade my ass. Slowly, the pain started to ebb, replaced by a dark, twisted pleasure. I found myself rocking back against him, desperate for more.
"f**k," Jaxon groaned. "Your ass is gripping me so tight. Like it was made for my cock."
He started to move then, shallow thrusts that grew deeper and harder. My t**s bounced wildly as he f****d my ass, the wet sounds of our f*****g filling the room.
"Faster," I panted, my eyes rolling back in my head. "f**k me harder, Jaxon!"
He obliged, slamming into me with brutal force. The bed shook with the force of our f*****g, the headboard slamming against the wall. My p***y was dripping juice down my thighs, throbbing with need.
"I'm close," Jaxon panted. "Where do you want it, sis? Want me to fill this tight little ass?"
I nodded frantically, too far gone to care about the consequences. "Yes, yes! c*m in me, Jaxon! I want to feel it!"
He groaned, burying himself to the hilt in my ass as he exploded inside me. I could feel his hot c*m flooding my insides, filling me up until it leaked out around his c**k.
The sight of his c**k buried in my ass, with his c*m dripping out, was so f*****g dirty that I came on the spot, my p***y clamping down on nothing. I screamed in ecstasy, convulsing beneath him as I rode out the most intense orgasm of my life.
Jaxon collapsed on top of me, both of us panting and covered in sweat. He nuzzled into my neck, pressing soft kisses to my skin.
"That was incredible," he murmured. "I've never c*m so hard in my life."
I could only whimper in agreement, too wrung out to form words. My body felt used and abused in the best possible way, and I knew I would be feeling the effects of our marathon f**k session for days.
But as we lay there basking in the afterglow, I couldn't help but feel a sense of unease creeping in. We had just crossed a major line, one that couldn't be undone. And with Jaxon still holding that screenshot over my head, I had a feeling this was only the beginning of our twisted forbidden affair.
