(Lila's pov)
The living room was dark except for the glow of the big TV screen.
Mom had picked some boring romantic comedy for family movie night, and the three of us were settled on the large sectional couch under a big shared blanket.
I sat in the middle, pretending to be interested in the movie while my body still buzzed from the kitchen encounter earlier that day.
Mark's c*m had dried on my thighs under my tiny sleep shorts, a constant reminder of how he had filled me on the counter. Mom was on my left, snuggled under the blanket with her eyes fixed on the screen.
Mark sat on my right, his big body relaxed but his hand already creeping toward me under the cover.
I kept my face neutral, staring at the flickering images, but my heart raced when his warm palm landed on my bare thigh.
He squeezed gently at first, then slid higher, fingers tracing the edge of my shorts. I bit my lip hard, trying not to react. Mom laughed at something on the screen, completely unaware.
"Relax, princess," Mark whispered so quietly only I could hear. His breath tickled my ear. "Just watch the movie like a good girl."
His hand moved boldly between my legs, cupping my p***y through the thin fabric of my shorts. I was already wet again, soaked from the constant ache he caused.
He rubbed me slowly, pressing the heel of his hand against my c**t until I had to clamp my thighs together to stop from moaning.
My n*****s hardened under my loose tank top, poking obviously against the material.
Mom shifted beside me, reaching for the popcorn bowl. "This is getting good, right honey?" she asked me cheerfully.
"Y-yeah, Mom. Really good," I managed, my voice strained as Mark's fingers pushed my shorts and panties aside.
Two thick digits slid along my slippery slit, coating themselves in my juices before pressing inside my tight hole. I gasped softly and covered it with a fake yawn, biting my lip harder.
Mark's fingers curled deep, stroking that sensitive spot on my front wall while his thumb found my swollen c**t and circled it relentlessly.
The wet squelching sounds were muffled by the blanket and the movie audio, but they felt deafening to me.
He pumped slowly at first, then faster, finger-f*****g me right there on the couch with my mother sitting just inches away.
"Such a naughty little cunt," he breathed against my ear, so low it was almost silent. "Soaking Daddy's fingers while we watch a movie with your mom. You love the risk, don't you baby girl?"
I nodded barely, eyes glued to the screen as my hips rocked subtly against his hand. Pleasure built fast, my walls clenching around his invading fingers. I reached under the blanket with my right hand and found the massive bulge in his pants.
His c**k was rock hard, straining against his sweatpants. I wrapped my fingers around the thick shaft through the fabric and stroked him slowly, matching the rhythm of his fingers inside me.
He added a third finger, stretching my p***y wider. The fullness made my toes curl under the blanket. Juices dripped down my ass crack onto the couch cushion.
I bit my lip so hard I tasted blood, fighting back the moans that wanted to escape. On screen, the couple kissed passionately, but all I could focus on was Daddy's fingers plunging in and out of my dripping cunt.
Mark's breathing grew heavier. He shifted closer, his free hand guiding mine inside his pants. I pulled his huge c**k out, the thick veiny length hot and heavy in my palm.
Precum leaked from the fat head as I stroked him firmly, twisting my wrist over the sensitive tip. He throbbed in my grip, growing even harder.
"Good girl," he murmured. "Stroke Daddy's c**k while I play with this tight pussy."
His fingers sped up, f*****g me deeper, curling harder against my g-spot. His thumb pressed firm circles on my c**t.
I was close, so dangerously close. My free hand gripped the edge of the blanket, knuckles white. Mom yawned and stretched beside me, her arm brushing mine for a second.
"Getting sleepy?" she asked.
"A little," I whispered back, voice shaky. Mark didn't stop.
If anything, he thrust his fingers harder, the obscene wet noises barely hidden. I pumped his c**k faster, feeling it pulse wildly in my hand.
"c*m for Daddy," he whispered right against my ear. "Quietly. Let me feel you squeeze my fingers while your mother sits right there."
The forbidden thrill pushed me over. My orgasm hit hard and sudden. My p***y spasmed violently around his three thick fingers, gushing juices that soaked his hand and the blanket.
I bit down on my lip desperately, body trembling as waves of pleasure ripped through me. My hand tightened on his c**k, stroking frantically through my climax.
Mark groaned softly, barely audible. His c**k swelled in my grip and erupted. Thick ropes of hot c*m shot out under the blanket, splattering over my fingers, my wrist, and onto the couch.
Spurt after spurt of his seed covered my hand as he kept fingering me through my orgasm, drawing it out until I was a shaking, overstimulated mess.
We both panted quietly, trying to recover. I slowly pulled my c*m-covered hand back, but Mark caught it and brought it to my mouth under the blanket.
"Clean it up, princess," he ordered in a whisper. I licked his c*m from my fingers obediently, tasting the salty thickness while pretending to watch the movie.
Mom stood up suddenly, stretching. "I'm going to grab some water and head to bed early. You two finish the movie without me."
My heart stopped. She leaned down and kissed my forehead, then Mark's cheek. "Goodnight, you two. Don't stay up too late."
As soon as her footsteps faded up the stairs, Mark yanked the blanket off us. His eyes were dark with fresh hunger. He pushed me back on the couch, spreading my legs wide and shoving my shorts completely off. His c**k was still hard, glistening with c*m and my juices.
"Finally," he growled, lining up the fat head at my entrance. "Now Daddy can really f**k you properly."
He slammed into me in one brutal thrust, burying his thick c**k balls-deep in my c*m-slick p***y. I moaned loudly now that we were alone, but he quickly covered my mouth with his hand.
"Not too loud, baby girl. She might still hear us," he warned, starting to pound me hard on the couch. The wet slapping sounds of his hips against my ass filled the room as he railed me.
I wrapped my legs around him, pulling him deeper. "Yes, Daddy! f**k me harder. Use your stepdaughter's pussy."
He hammered into me relentlessly, his heavy balls slapping my ass. Just as another orgasm started building inside me, we heard the floor creak upstairs.
Mom was still moving around up there. Mark grinned wickedly, not slowing down at all. He leaned down and bit my neck, marking me as he thrust even deeper.
"She is right above us," he whispered. "And I am not stopping until I fill this cunt again.
My eyes widened in panic and excitement as his c**k drove into me harder, pushing me closer to the edge while my mother's footsteps sounded faintly overhead.
