100 Nights of Forbidden Fire

The Line They Shouldn't Cross

THE house felt different the moment Elena stepped into it again. Maybe it was the silence, maybe it was the faint smell of cedar and aftershave drifting down the hallway… or maybe it was simply because he was here.

She hadn’t seen Adrian in eight months.

Eight freaking months since their parents’ awkward backyard wedding. Eight months of dancing around the fact that they were now step-siblings. Eight months of ignoring the strange electricity that had been there long before anyone signed a marriage certificate. Eight months of pretending it meant nothing.

But the moment she heard his footsteps coming down the stairs, her breath stilled in her chest like a trapped bird.

He appeared at the bottom step, hand sliding casually along the railing, wearing that same quiet confidence that made her pulse skip. He now looked taller, a sharper jaw, broader shoulders. Life had been good to him, maybe too good.

“Elena.” His voice came out smooth and calm… too calm. “You came.”

She swallowed. “Mom insisted.”

“So did my dad.” His eyes flicked over her once, a controlled sweep he acted like he didn’t make. “Long time.”

Yeah. Too long. Long enough for feelings to grow into something that shouldn’t exist.

She forced a smile.

“How have you been?”

“Busy.” He leaned against the wall, arms folding across his chest. Veins, muscles, she noticed all of it, more than she should.

“You?”

“Same.” Her voice shook slightly. She hated that he still made her nervous. “I didn’t know you would be here.”

He lifted a brow.

“It is my house too.”

Right. Their parents had bought it together after the wedding. A place for both families to merge… never considering what merging did to them.

She adjusted her bag on her shoulder, trying to act unaffected.

“Well, I’m just here for the weekend.”

His gaze didn’t waver.

“I know.”

Then there was a beat of silence. It was thick and charged, making it impossible to escape.

“Mom is at the store,” she said quickly. “She won’t be back for an hour.”

His jaw tightened. A subtle reaction, but she caught it.

“So it is just us?” he said quietly.

Her heartbeat stumbled.

“Just for a little while,” she whispered.

Something unspoke passed between them, dangerous, heavy, and familiar. Something they had been avoiding since the night of the wedding when they danced too close, laughed too freely, and stepped outside to “get some air,” only to end up standing inches apart in the dark until someone called their names.

She still remembered the way he had looked at her under the porch light. Like he wanted something he knew he shouldn’t take.

He cleared his throat first this time.

“I will… show you your room.”

She followed him upstairs, trying not to breathe too deeply. He smelled like cedar, mint, and a little like memory. Halfway down the hallway, he stopped in front of a door and pushed it open.

“You can take this one,” he said. “I moved my stuff out.”

Her eyes snapped to him.

“You moved out of your room? Why?”

He paused, then shifted his gaze away.

“It felt…”

There was a beat.

“…weird,” he finished.

Weird.

Meaning what, exactly?

She stepped into the room, placing her bag on the bed. When she turned back around, he was leaning in the doorway, watching her with an expression too unreadable to untangle.

“Adrian,” she whispered, “we are adults. We can be normal.”

He let out a soft, humorless laugh.

“Yeah? Because we have always been so good at that.”

She looked down.

“We are step-siblings now.”

“I know,” he said, voice dropping lower. “Trust me, Elena. I know.”

She didn’t mean to move closer. She didn’t mean for their distance to shrink to only a few steps. She didn’t mean to look up at him with her heart in her throat. But she did.

And he didn’t step away.

His breath hitched, barely, but she heard it. She felt it.

“You should unpack,” he said softly, though he made no move to leave.

“Yeah,” she whispered, though she didn’t move either.

Their parents’ laughter echoed faintly from a memory downstairs. The safe part of her mind screamed for space, distance, logic.

But his hand lifted, just slightly as if it wanted to reach for her before he caught himself.

“Elena.”

Her name on his lips had no right sounding like that.

She stepped back first. Barely. Just a fraction of a step, but it snapped something between them.

He inhaled slowly, steadying himself.

“I will… be downstairs,” he murmured.

She nodded, though her chest felt tight. “Okay.”

He turned and walked away, shoulders tense, every part of him controlled, too controlled. She waited until he disappeared around the corner before she sat on the bed, breathing shakily.

This was going to be a long weekend. A dangerous one. A weekend where one wrong moment… one wrong look… one slip of control…

Could burn everything.

***

The next morning at exactly 9am, the whole family was at the table, Mrs. Dothan was on her feet, serving toast into everyone's plate.

“Kids—” she started and Elena quickly interrupted.

“Kids?” She scoffed, glancing at Adrian who had his eyes squinted.

Their parents exchanged glances and burst into laughter.

“My bad, dear. Lady and gentleman,” she corrected and sat down, picking up her table cloth, “your Dad and I would be out for a function immediately after breakfast. So you guys, take very good care of yourselves,” she finished.

Elena gasped. Adrian scoffed, dropping his fork. Whether it was deliberate or not, no one knew.

“Oops. Sorry,” he said and quickly glided down to pick it up, and when he did, he saw what he wasn't expecting.

Elena's legs were wide apart, he could clearly see through her short denim skirt, her fine sexy thighs, her cream pantie, he could see everything. Quickly, he glided out and at the minute he did, their eyes met. Her expression was unreadable but whatever message she was trying to pass on, he had gotten it.

The rest of the breakfast was eaten in silence. Soon, their parents were out, leaving them both at home, alone!

They had said nothing about the incident at the dining, but kept themselves mute as though nothing had happened, retired to their rooms and shut their doors.

About three hours later, Adrian opened the door to his room and headed for the kitchen. He walked straight to the refrigerator and got out a jug of liquid milk. He dropped it on the counter. There was already a jar of chocolate cereal, then he turned to get a cup.

At this juncture, Elena sneaked in and walked straight to the counter, sitting on the stool and reaching out for the jar, Adrian reached out for it too and their hands brushed against each other.

“Hey, give me that,” he said.

She pouted, shaking her head sideways.

“No, you give me that,” she said.

“Give me that or I will tear your t**s open,” he threatened.

She chuckled.

“I don't care, f*****g dude. I dare you!” She challenged him.

He wasted no time. Adrian quickly reached out for her elastic blouse and tore it open, revealing her set of round firm t**s.

“Woah!” He exclaimed.

“Now, are you okay?” She asked and he scoffed. “Okay?”

He said nothing, his eyes just lingered on the set of sweet t**s staring at his face.

“So now will you let me have the cereal?”

He chuckled.

“Nope,” he snapped, “till I see down there too,” he pointed at her honeypot.

She scoffed.

“Oops. I don't care,” she said and raised up her left leg, placing it on the stool, revealing her cream pants.

Quickly, he reached out, roughly shifted the pants to the right to reveal her very pink fluffy folds. Damn! It was so clean.

“Now, I can have it,” she pulled the jar towards her. Adrian didn't immediately take away his hand, he couldn't, he instead, slipped in his index finger and began finger f*****g her.

“We have always wanted this,” he said.

She said nothing, but just sat still to savor the pleasure.

He slipped in two of his fingers and went deeper, sending her moaning. Her eyes squinted in pleasure.

He stopped and pulled down his shorts in a haste, his solid member popped out, standing hard and rigid.

“Suck me,” he said.

She got down the stool and knelt down, taking his c**k in her left hand, she spat on the tip and began rubbing it whole. Soon she sent it into her mouth and began sucking. It filled her mouth. She sucked at it as though it was laced with honey, as though her life depended on it.

When her left hand alone became insufficient, she joined the other hand, holding his microphone with her two hands and sucking so intensely, gliding it in and out of her mouth, rolling her tongue all over it in ecstasy.

Then as if on impulse, he pulled the jug of milk towards him and uncorked it, then he poured a reasonable amount of it on his d**k, and she intensified the sucking.

“Mm. Sweet,” she said, licking out everything. She went for the balls, sucking at them as well. Adrian moaned.

As she sucked, she circled her right breast and n****e with her hand, gently cupping and m**********g with it, moaning in the process.

“Get up,” he said and she obeyed, sat back on the stool and spread out her legs the way she had earlier done. He shifted her pants, brought his c**k closer to her p***y, and slowly and gently, he glided in.

“Ahhhhhhhh!” She screamed out, cupping her hand over her mouth, and looking directly at him. But he wasn't having his eyes on her, his eyes were on the business downwards. He concentrated squarely on getting his manhood into this pinky fluffy p***y.

The cap entered, he pushed in again and two inches followed, again, an inch followed. And finally, everything went in, his balls dangled out on her skin as he began slamming in and out.

“Ahh!” She moaned, biting at her lips in a bid to shut herself up. The kitchen stool with which she sat on made its own noises and scratches on the floor, to the rhythm of the thrusts.

Adrian kept thrusting in and out, slowly and intensely, fire and forbidden. The s*x was mad, each thrust driving them both insane, sending shivers down their spines.

She raised up her skirt to give him easy passage into her, and he glided more into her honeypot, quickening his pace with each passing second, their skins slapping into each other. She moaned out again, louder.

He quickly placed his right hand over her mouth to lessen her sounds, while his left hand rested on his waist, he kept thrusting in and out of her.

“Ahhh!” He growled slowly, while she kept making muffled moans into his hand.

He suddenly slowed down, making slow thrusts and glides. But then—

“What are you guys doing?” A voice asked and he quickly pulled out, his hard member standing erect, pointing in the direction he faced. As he did, she quickly pulled up her blouse, covering herself properly. It was their mom, their parents were back!

But she couldn't see from their waists down, they were behind the counter and she stood by the door, smiling at them.

“Oh mum. You are back,” Elena said, smiling and reaching for the cereal jar.

“Welcome, mum,” Adrian greeted.

“Thanks, Adrian. Eating cereals, Elena. Don't forget what the doctor said,” she turned to leave.

“Ugh, yes… yes mum. Won't,” she replied, scratching her nape.

Mrs. Dothan walked out and Adrian stood Elena from the stool and sat on it, rubbing his d**k. Then he held her by the waist, she spread her legs apart and gently sat on him, slowly sinking into him, inch by inch until he was fully inside her, and they began f*****g again.
