The first week back was pure torture.
Millie moved around the house like a ghost, hyper-aware of every creak in the floorboards and every time her mother’s voice echoed from the kitchen. Richard played the part of the perfect stepfather flawlessly. With polite smiles at dinner, casual conversations about work. But behind closed doors, his eyes burned with barely contained hunger. And while all this was happening, her mom didn't take any notice. She was always involved with one work or call or the other.
It was the third night when the tension finally snapped.
Her mother had gone to bed early, exhausted from her latest “work trip.” The house was quiet except for the low hum of the air conditioner. Millie waited in her room for twenty agonizing minutes before slipping down the hallway in nothing but an oversized t-shirt. She moved. Richard’s door was already cracked open. The moment she stepped inside, he was on her. He pulled her against him, mouth crashing down in a hungry kiss as he backed her toward the bed. His hands roamed possessively squeezing her ass, sliding under her shirt to cup her bare breasts. She let out a soft moan.
“You have no idea how hard it’s been keeping my hands off you,” he growled against her lips. “Sitting across from you at dinner while knowing this p***y is still full of my c*m from yesterday.”
Millie whimpered, already soaked. “Daddy, please…”
He spun her around and bent her over the edge of the bed. No foreplay tonight. He shoved her shirt up and thrust into her in one hard stroke, burying himself balls-deep.
“f**k,” he hissed. “So f*****g tight for Daddy.”
Millie buried her face in his pillow to muffle her moans as he f****d her hard and deep. The bed creaked softly with each powerful thrust. The risk of her mother waking up just down the hall made everything ten times hotter.
“Quiet, baby girl,” he warned, spanking her ass sharply. “You don’t want Mommy hearing what a dirty little slut her daughter is for me.”
The filthy words made her clench around him. Richard reached around and rubbed her c**t roughly while pounding into her.
“Gonna fill you again,” he whispered. “Gonna keep breeding this p***y until it takes. I want you to be swollen with my baby while you sit at the dinner table pretending nothing’s changed.”
Millie came hard, biting the pillow to silence her cry. Her orgasm triggered his own, he buried himself deep and pumped her full, groaning quietly as he emptied himself inside her. They collapsed onto the bed, breathing heavily. Richard pulled her close, spooning her from behind, his c**k still nestled inside her.
“I can’t stop thinking about you,” he admitted, voice low. “Every time I see you, I want to bend you over and claim you again.”
Millie smiled, pressing back against him. “Then do it. Whenever you want. I’m yours now.”
The next few days fell into a dangerous rhythm.
Mornings, Richard would pull her into the bathroom while her mother was still sleeping, f*****g her quickly against the sink. Evenings, when her mother went for her nightly wine on the porch, he’d have Millie on her knees in the laundry room, sucking him deep until he came down her throat. One afternoon, when her mother ran to the grocery store, Richard didn’t waste a second. He took Emma right on the living room couch, the same couch where they used to watch family movies. He had her ride him reverse cowgirl, hands gripping her hips as she bounced on his thick c**k.
“Look at you,” he groaned. “f*****g your stepdad in the middle of the house like a little whore.”
Millie moaned, grinding down harder. “I love it… I love being your secret.”
He pulled her back against his chest, one hand around her throat, the other rubbing her c**t.
“c*m for Daddy,” he ordered.
She did… hard… her juices soaking his lap. Richard followed, flooding her again with hot c*m. As they caught their breath, reality crept back in.
“We have to be careful,” he said, kissing her shoulder. “But I’m not stopping this. You’re mine now, Millie. Completely.”
She turned in his arms and kissed him deeply.
“I don’t want you to stop,” she whispered. “Ever.”
Their secret affair had officially moved from the lakeside to their own home which was intensely riskier, hotter, and more addictive than either of them could have imagined.
And Millie knew, deep down, that this was only the beginning of their dirty sin.
