Taking Her Sister’s Husband’s Cock (I)

Bianca had always watched Carlos Williams from behind his office glass door, teeth clenched, thighs tight, wanting what she was never supposed to want. He was her cold, ruthless, untouchable billionaire boss. And her sister’s husband. The man who ruled boardrooms with a glare and gave his loyalty to no one but family, especially Sarah, his wife.

She watched how his shirt hugged that broad, hard chest, how his jaw flexed when he was pissed. But it was the way he looked at her when no one else was around that wrecked her, like he was thinking about bending her over his desk and shoving his cock inside her pussy so deep she’d forget her own name. It wasn’t sweet. It was filthy. And it made her pussy throb like she already belonged to him.

Bianca was Carlos secretary. She got the job because of her sister, his fucking wife. It was pure nepotism, soaked in guilt. But that didn’t stop the thoughts.

Carlos, on the other hand, had been testing Bianca’s limits for weeks, brushing close, giving orders in that deep, commanding voice, staring too long when no one else was watching. And she let him. Worse, she wanted him.

She thought about him fucking her all the time. Spread across his desk, taking him deep, moaning his name while her sister’s picture sat on the wall, watching.

It made her feel sick. Dirty. Like a whore without shame. But she kept thinking about it anyway, because she wanted it more than she’d ever admit.

Carlos had told Bianca to bring him a couple of files a few minutes ago. Now, here she was, hesitating at his office door.

She took a breath, opened the door, stepped inside, and closed it behind her.

The office was quiet. It was already past eight, which meant almost everyone at the company had gone.

She walked towards his desk with the files in her hands, spine straight, skirt too tight, eyes burning with the kind of need she didn’t want to name.

“Here are the files,” Bianca spoke up.

Carlos sat in his chair, his eyes fixed on the tablet in his hand. He didn’t look up.

“Put it on the desk,” he muttered.

She dropped the file on his desk, but she didn’t leave. She just stood there. Carlos finally raised his head and looked at her, then stood and walked around the desk slowly, like a predator.

“You think I haven’t noticed the way you look at me?” he asked, voice smooth, dark.

Bianca’s breath hitched. She opened her mouth, but no words came.

He stepped closer to her, placed his hand on her hip, and began brushing it with his thumb.

“You’re too fucking tempting, Bianca. And you know it.”

“What are you doing? Your wife is my sister…” Bianca whispered, more to herself.

He chuckled, grabbing her by the waist, pulling her against his body.

“Then be a good sister and keep a secret.”

His lips were on hers before she could protest. His kiss wasn’t soft. It was filthy, claiming, like he owned her mouth the way he owned everything else.

Bianca’s body betrayed her instantly. She melted into his hold, gripping his shirt as her thighs clenched.

Her sister’s face flashed through her mind. The woman she was betraying with every breath and she still couldn’t stop.

“You’re wet already, aren’t you?” he growled against her lips, sliding his hand up her inner thigh. “I barely touched you, and you’re fucking soaked.”

She whimpered, pressing against him.

“I couldn’t stop thinking about you…”

“And now you don’t have to.” Carlos’s voice dropped. “I’m going to fuck you on this desk. You’re not leaving until you’ve screamed my name.”

And she didn’t argue. She was too far gone. Too turned on. Too obsessed.

His hands were already on her hips, dragging her forward across the smooth glass surface of his desk until her thighs hit the edge. Her breath hitched as his fingers moved under her skirt, bunching it up around her waist with no hesitation.

The air was cold against her bare skin. She wore a black lace thong, delicate, low-cut, and barely covering anything. The lace, already soaked through, clung to her like a second skin.

His gaze dropped.

“You wore these for me,” he muttered, more statement than question, voice thick with dark approval.

Bianca couldn’t form a reply. Her throat was dry and pulse pounding between her legs. Her thighs parted slightly, needy, aching, inviting. She didn’t try to be coy. She couldn’t. Not when her pussy pulsed with every second of delay.

Carlos grabbed her delicate lace and tore it off her like it was nothing. The sound of it ripping echoed in the quiet office.

Bianca’s breath stuttered.

He grabbed her thighs, rough and demanding, lifted her like she weighed nothing, and set her down on his cold glass desk. The edge dug into her ass as he shoved her legs apart, wide and open, like she was already his to use.

Then his fingers traced from her inner thighs to her wet pussy, slow and deliberate. Her body reacted instantly. Her skin tingled, and her breath caught.

She gasped, her back arching as his fingertips found her clit, slick, swollen, and already aching for more. He didn’t ease her in. He shoved two fingers deep into her pussy, thrusting hard and fast, filling her so suddenly her thighs jerked.

“Fuck,” Carlos growled, watching Bianca’s face twist as she clenched around him. “So fucking tight.”

A moan slipped out of her lips, sharp, breathless, raw. She didn’t care if anyone heard. She couldn’t think. His fingers were fucking her slowly, curling just right, dragging against her walls in a way that made her legs shake.

Her hands scrambled behind her, gripping the edge of the desk, nails biting into the polished surface.

“Please,” she whispered, voice cracked and needy.

He leaned in, his mouth brushing her ear.

“Please what?”

She whimpered when he shifted, adding pressure with his thumb on her clit. He circled it lazily, cruelly, like he wanted to drive her insane.

“I need more,” she managed to say. “I need—”

“You need to remember whose fingers are inside you,” he snapped, curling his fingers and fucking her hard. Her body jolted. “You walked into this office soaked. You’ve been begging for this without saying a word.”

“Yes… mhhmmmm… fucckkkkkk.”

Bianca’s moan grew louder, raw and desperate. She couldn’t hold back as his fingers quickened, tightening their grip, pulling her closer to the edge until her thighs trembled uncontrollably.

Every muscle in her body tightened. Her mouth dropped open. Her eyes rolled back as she moaned loudly, “yes… fuckkkkk… I fucking love this.”

Her orgasm hit like a wave. It was violent, messy, and unstoppable. She convulsed around his fingers, hips grinding into his hand, breath breaking into stuttering gasps as her whole body rocked through the release.

And just when she thought he’d pull away, give her room to recover, Carlos did the opposite.

He pulled his fingers out of her pussy slowly, dragging them against her entrance, glistening with her release. Then he brought them to her lips.

“Taste it,” Carlos said, eyes locked on Bianca’s.

She didn’t hesitate.

Bianca took his fingers into her mouth, sucking them deep, tasting herself on his skin, her tongue curling around his fingers like she needed more. Her moans vibrated against his knuckles.

Carlos eyes darkened.

“Good girl. I’m gonna fuck you so hard, you won’t even remember your fucking name,” he growled.

Carlos then undid his belt. The sharp clink of the buckle sent a thrill through her chest.

“Get the fuck ready,” he growled again, shoving Bianca flat on the desk as he yanked his pants open. His cock was thick, hard, and already dripping. “I’m not stopping until you’re wrecked and leaking with my cum.”
