Rule Number 4: Always Stay Naked!

Tara straddled Zane’s lap completely naked, her thick thighs spread wide over his muscular body. His rock-hard cock stood straight up between them, the fat head already slick with her leaking juices. She gripped his shoulders, eyes blazing with a mix of anger and burning lust as she slowly lowered herself onto him.

“You’ve been stalking me through those videos,” she breathed, sinking down inch by thick inch until her pussy swallowed every veined inch of his cock. “Now show me how much you need this forbidden pussy, stepbrother.”

Zane groaned deeply, hands gripping her wide hips as her tight walls clenched around him. “I set up the ankle twist, Tara. Not to hurt you… but to keep you here. I saw how burned out you were on your streams. The pressure, the exhaustion. I needed to protect you. To take care of you properly.”

Anger flashed in her eyes even as she started riding him, sliding her soaked cunt up and down his thick shaft. “You manipulated me?” She slammed down harder, her heavy tits bouncing in his face. “Fuck… you’re so deep.”

Zane thrust up to meet her, one hand sliding up to cup her breast and pinch her stiff nipple. “Yes. Because I love you. Not just as my stepsister. I’ve wanted to claim this body and this heart for years.” His other hand rubbed her swollen clit as she rode him faster, wet sounds filling the bedroom.

The betrayal melted under the heat. Tara’s movements turned desperate, angry fucking shifting into raw, loving passion. “Then breed me, Zane. Prove it.”

He flipped them suddenly, laying her on the couch and driving into her in deep, powerful strokes. Her legs wrapped around his waist as he pounded her cunt, the couch creaking beneath them. “Take every drop, baby. This pussy is mine to fill.” He sucked hard on her nipples, biting gently while slamming against her cervix.

Tara came hard, her pussy spasming and squirting around his pistoning cock. Zane didn’t stop. He carried her naked, cum-dripping body to the kitchen counter, set her ass on the edge, and hooked her legs over his shoulders. In this mating press he fucked her even deeper, his heavy balls slapping her ass with every brutal thrust.

“Gonna put a baby in you, sis. Watch this belly swell with our child,” he growled, rubbing her lower stomach as he railed her. Tara’s full breasts jiggled wildly. She screamed in pleasure, cumming again as he flooded her womb with thick, hot ropes of cum.

They moved to the floor, Tara on top again, riding him reverse cowgirl so he could watch his cock stretch her creamy pussy. He spanked her ass red, praising her between thrusts. “Such a perfect girl. So strong and beautiful. I’ll always protect you. Always worship you.”

Hours blurred into a breeding marathon. He took her bent over the kitchen island, slow and deep with tender kisses on her back. Then against the hallway wall, lifting her completely off the ground as he pounded up into her. Every position ended with another creampie, his cum overflowing from her well-fucked hole and running down her thighs.

Through it all, Zane mixed rough dominance with loving care. Forehead kisses during thrusts. Whispers of “I love you” as she came. Gentle wipes with warm towels between rounds. He massaged her sore ankle and muscles even while buried inside her.

Exhausted and glowing, they collapsed naked in each other’s arms on the living room couch. Zane held her close, stroking her hair and rubbing her cum-filled belly tenderly.

A car door slammed outside.

They froze. Headlights flashed through the window. Their parents had arrived a full day early.

Zane’s eyes darkened with fierce, possessive determination as he pulled Tara’s naked body tighter against him, his cock already twitching back to life against her thigh.

“We’re not stopping,” he whispered, kissing her deeply. “Not ever.”

Parents’ voices drifted up from downstairs as they unpacked suitcases and called out greetings. Zane had Tara pinned naked against the inside of his bedroom door, her back to the wood, one thick leg hooked over his hip. His rock-hard cock slid slowly and deeply into her cum-soaked pussy, stretching her creamy walls inch by inch while his hand covered her mouth.

“Stay quiet and cum for your stepbrother one more time, baby,” he whispered hotly against her ear, eyes locked on hers. “Then I’ll make this real.”

Tara moaned softly into his palm, her full breasts pressed against his muscular chest. Her pussy fluttered and clenched around his thick shaft as he rolled his hips in deep, grinding thrusts, the wet squelch barely muffled. Every slow drag of his veined cock rubbed perfectly against her g-spot, churning the loads he had already pumped into her throughout the day.

Downstairs, their mom laughed at something their dad said. The risk made Tara’s clit throb harder. Zane removed his hand and kissed her fiercely, tongues tangling as he fucked her standing against the door with long, possessive strokes. “I love you, Tara. Not just fucking you. I love your fire, your strength, everything.”

Tara’s eyes watered with emotion even as pleasure built. “I love you too, Zane… fuck, you’re so deep. Breed me again.”

He lifted her fully, both legs wrapped around his waist, and carried her to the bed without pulling out. He laid her down gently and climbed over her in missionary, folding her legs back as he drove in hard and deep. The bed creaked softly. His heavy balls slapped her ass with every thrust, his pelvis grinding against her swollen clit.

“Take every drop, sis. I’m claiming this fertile pussy forever,” he growled, sucking hard on her bouncing tits, biting her nipples while pounding her cervix. Tara’s curvy body shook beneath him. She came violently, pussy spasming and squirting around his pistoning cock, soaking the sheets.

Zane followed right after, burying himself to the hilt and erupting. Thick, hot ropes of cum flooded her womb again, pulse after pulse until her belly felt full and his seed leaked out around his shaft.

He stayed inside her, kissing her forehead, her lips, and her neck with tender aftercare. “You’re my safe place. My everything. We’ll figure out the rest together.”

A soft knock sounded on the door. “Kids? You up there? Dinner in twenty!”

Zane’s eyes flashed with dark possession. He pressed a finger to Tara’s lips and slowly pulled out, watching his cum pour from her gaping, well-fucked hole. He quickly cleaned her with a warm towel, then slipped a delicate promise ring onto her finger while kissing her naked belly.

“We’re not hiding forever,” he whispered. “Our family starts now.”

Tara smiled, glowing, and slipped the positive pregnancy test she had taken earlier into his hand. Two pink lines.

The knock came again.
