Forbidden Affair With My Step Uncle

CHAPTER 10 : Surrender.

CALLAHAN’S POV ~

The phone kept ringing down the hall. Victor’s ringtone cut through the space between them.

Callahan froze above her, his thick c**k pressed right against her wet opening. The wide head was already stretching her a little. Isabella’s legs were wrapped tight around his waist. Her nails dug into his shoulders. She was breathing fast, eyes locked on his.

“Don’t answer it,” she murmured against his ear. “Please. Not now.”

Callahan looked toward the door. His face was full of pain and want at the same time. Then he made a low, broken sound in his throat.

He reached down, took hold of his c**k, and pushed in slow.

Isabella gasped loud. He was so thick. So big. He stretched her open inch by inch until he was all the way inside. She felt so full. So claimed.

“Mmm, you’re dripping for me,” he teased, voice low. “Greedy little thing.”

He stayed still for a second, forehead pressed to hers. His eyes were dark and soft at the same time.

“I’ve wanted this for so long,” he growled low. “Too long. God, I’m sorry… but I can’t stop now.”

Then he started to move.

Isabella’s head fell back against the sheets with a sharp cry. He was so thick it burned in the best way, stretching her walls, filling her until she felt split open and claimed at the same time. Her inner muscles fluttered around him, trying to adjust, trying to pull him deeper.

“f**k,” Callahan hissed through clenched teeth. “So…fucking…tight.”

He sank to the hilt in one final thrust, hips flush against hers, balls pressed tight to her ass. For a heartbeat neither of them moved. They just shared their breaths – locked together in the wreckage of every rule he’d tried to enforce.

Isabella whimpered, fingers tangling in his wet hair. “Move. Please move.”

Callahan pulled back almost all the way—until only the head remained inside—then slammed back in, hard enough that the headboard thudded against the wall.

Isabella arched, a sob of pleasure tearing from her throat.

He did it again. And again. Each thrust deeper, rougher, more desperate. The wet slap of skin on skin filled the room, mingling with her moans and his low, guttural groans.

He f****d her like a man who’d been starving for years and finally found food – relentless, possessive, no gentleness left.

“You feel that?” he growled against her ear, hips snapping forward. “That’s what you’ve been begging for. Every tease. Every flash. Every time you rubbed against me and walked away smiling. This.”

“Yes– God, yes–” Isabella’s voice cracked. Her nails raked down his back hard enough to draw blood. “Harder. Don’t stop.”

He hooked one of her legs over his shoulder, changing the angle so he hit deeper – right against that spot that made stars explode behind her eyes. She screamed his name, walls clamping down so tight he nearly lost it right then.

“f**k, you’re gonna make me come too fast,” he rasped, slowing for a second, grinding deep circles instead of thrusting. “Been too long. Been thinking about this p***y for years.”

Isabella’s eyes flew open. “Years?”

He leaned down, forehead pressed to hers, hips still rolling in filthy, slow grinds. “Since you turned eighteen. Every summer visit. Every time you wore those little shorts and sat on my lap during movie night. I hated myself. Jerked off in the shower hating myself. And now you’re here — wrapped around my c**k like you were made for it.”

Tears pricked her eyes – not from pain, from the raw honesty in his voice.

“I wanted you too,” she confessed on a gasp. “Since I was sixteen. I used to touch myself thinking about you calling me into your study, bending me over the desk…”

Callahan groaned, hips jerking forward involuntarily. “Don’t—f**k—don’t say that.”

“Why not?” She clenched around him deliberately, milking him. “It’s true. I’d come so hard imagining you finally giving in. Finally f*****g me like you owned me.”

He snapped.

Any last thread of restraint dissolved.

He pulled out suddenly— making her whine at the loss– flipped her onto her stomach, yanked her hips up, and drove back inside from behind in one brutal thrust.

Isabella buried her face in the pillow, muffling a scream as he pounded into her, one hand fisted in her hair, the other gripping her hip hard enough to bruise.

“Mine,” he snarled, voice wrecked. “Say it.”

“Yours—” she sobbed. “Yours, Callaha…fuck—yours—”

He reached around, fingers finding her c**t, rubbing fast, rough circles while he railed her from behind. The angle was merciless; every thrust slammed against her G-spot until her legs shook and her vision blurred.

“Come for me,” he ordered. “Come on my c**k like the good girl you pretend to be.”

Isabella shattered.

Her orgasm hit like a tidal wave—walls pulsing, thighs trembling, a broken cry ripping from her throat as she soaked him, dripping down his balls and onto the sheets.

Callahan followed two thrusts later– burying himself to the hilt, hips grinding deep as he came with a guttural roar. Hot, thick ropes flooded her, spilling out around his c**k as he kept thrusting through the aftershocks, marking her inside and out.

They collapsed together—sweaty, shaking, breathless.

The phone finally stopped ringing.

Callahan looked down at her. His eyes were full of guilt, but also something warm and real.

“Victor called three times,” he said quietly.

Isabella touched his face. “I know.”

He kissed her again, soft and slow. “I didn’t answer.”

She smiled a little. “What happens now?”

His hand slid down and rested on her belly, right where he was still buried inside her.

“Now you stay right here,” he whispered. “I’m not letting you leave this bed tonight. I’m going to f**k you again… slower this time. I want to feel every second of you.”

He rolled his hips once, gentle, making her gasp.

“And tomorrow,” he added, voice rough, “when Victor calls again… we’ll figure out how to lie. Because I can’t give you up. Not after this.”

Isabella pulled him closer with her legs.

“Good. Because I don’t want you to.”

Callahan kissed her deep. Then he started moving again — slow, deep strokes that made her moan softly into his mouth.

The phone started ringing again.

They both heard it.

But they didn’t stop.

In that moment, they both knew they had committed the sweetest sin of their lives, and they wouldn’t take it back even if they could.
