The following evening felt electric. Victoria had left for a dinner meeting in the city and wouldn’t be back until late. The storm had only grown stronger, thunder rumbling in the distance like a warning neither of them wanted to heed.

Elena had tried to stay away. She spent the afternoon reading in her room, but her mind kept drifting back to Marcus’s fingers inside her, his voice claiming her pussy as his own. By dinner, the tension was unbearable. They ate together in near silence, stealing glances across the table. Every look felt loaded.

After they cleared the dishes, Marcus poured them each a glass of wine. They moved to the living room, where the fire was crackling warmly against the cold rain hammering the windows.

“Come here,” he said, setting his glass down.

Elena went to him. The moment she was within reach, Marcus pulled her into a deep, hungry kiss. There was no more hesitation. His tongue claimed her mouth as his hands roamed her body—squeezing her ass, cupping her breasts, pulling her tight against his rock-hard cock.

“I’ve been thinking about this all day,” he growled against her lips. “About how wet you got for Daddy’s fingers. About how tight you felt. I need more, baby girl. I need all of you.”

Elena moaned into his mouth. “We really shouldn’t… Mom could come home…”

“She won’t be back for hours.” He spun her around and walked her toward the large leather couch. “And even if she did, I’m not sure I could stop tonight.”

He bent her over the back of the couch, her hands bracing on the cushions. Marcus yanked her shorts and panties down in one motion, exposing her ass and dripping pussy to the cool air. He dropped to his knees behind her, spreading her cheeks and dragging his tongue through her soaked folds.

“Oh fuck—Daddy!” Elena cried out, pushing back against his face.

He ate her like a starving man—licking, sucking, tongue-fucking her until her legs shook. When she was right on the edge, he stood, shoving his sweatpants down. His massive cock sprang free, thick, veined, and leaking precum. He rubbed the fat head up and down her slit, teasing her clit.

“Tell me you want it,” he demanded, voice rough.

“I want it,” she gasped. “Please, Daddy… fuck me.”

Marcus gripped her hips and pushed forward. The thick head stretched her open, then inch after inch of his huge cock sank into her tight pussy. Elena moaned loudly at the overwhelming fullness. He was so much bigger than anyone else. He bottomed out, balls deep, with a deep groan.

“Fuck, baby girl. This pussy is gripping me so perfectly. Like it was made for Daddy’s cock.”

He started thrusting—slow and deep at first, letting her adjust to his size. Then harder. Faster. The sound of skin slapping skin mixed with the rain and thunder. Marcus reached around to rub her clit while pounding into her.

“You’re mine now,” he growled, leaning over her back. “This tight little cunt is Daddy’s. I’m going to fuck you raw and pump you full of my hot cum.”

Elena was lost in pleasure, pushing back to meet every thrust. The taboo of it all—being bent over and fucked by her stepfather in the family living room—only made her wetter.

“Daddy… I’m going to cum…”

“Come on my cock,” he ordered, slamming into her harder. “Milk me, baby girl.”

Her orgasm exploded through her, pussy clenching and fluttering around his thrusting shaft. Marcus roared, burying himself to the hilt as he came. Thick, powerful ropes of hot cum flooded her womb, pulse after pulse, filling her completely. He kept grinding deep, making sure every drop stayed inside her.

When he finally pulled out, a thick stream of his cum dripped down her thighs. Marcus reached down and pushed some of it back inside her with his fingers.

“Such a good girl taking Daddy’s load,” he praised, kissing the back of her neck.

They stayed like that for a long time—him holding her, his cum leaking from her used pussy—while the storm raged outside.

But as the high faded, guilt began creeping in for Elena. This was only the beginning of something far more dangerous.
