Forbidden Heat: A Sibling's Secret

Chapter 1: After Hours Temptation

The day had been a brutal slog, and I stumbled into the house, my muscles aching from hours of relentless labor. My little sister, Mia, was already there, lounging on the couch in nothing but a tight tank top and shorts that barely covered her toned thighs. Her sharp green eyes flicked up to meet mine, a smirk playing on her lips as she stretched lazily, her body a tantalizing curve against the cushions.

'Rough day, big brother?' she teased, her voice dripping with mock sympathy. 'You look like you could use some... relief.'

I rolled my eyes, dropping my bag by the door. 'Don’t start, Mia. I’m too tired for your games.'

But she wasn’t having it. She slid off the couch, her movements deliberate, predatory, as she sauntered over to me. 'Oh, come on,' she purred, her fingers brushing against my chest. 'I’m not playing games. I’m offering a service. You’ve been working so hard... let me take care of you.'

I raised an eyebrow, trying to keep my cool despite the heat already stirring in my veins. 'And what exactly are you offering, little sis? A back rub? A beer?'

Her smirk widened into a wicked grin as she dropped to her knees right there in the living room, her hands already working at my belt. 'Something better,' she whispered, her voice low and sultry. 'Something to make you forget every damn ache in that body of yours.'

I should’ve stopped her. I knew it. But the way her eyes locked onto mine, fierce and unapologetic, made my resolve crumble. 'You’re trouble, you know that?' I muttered, my voice rough as her fingers deftly freed me from my jeans.

'Trouble’s my middle name,' she shot back, her tone sharp and playful. 'Now shut up and let me work.'

Her lips were on me before I could protest further, warm and wet, wrapping around my cock with a confidence that sent a jolt straight through me. She wasn’t shy, not submissive—hell no, Mia was in control, her tongue swirling with precision as she took me deeper. I groaned, my hands instinctively tangling in her hair, but she didn’t flinch. Instead, she looked up at me with a glint of challenge in her eyes, daring me to keep up.

'Damn, Mia,' I growled, my voice thick with need. 'You’re gonna kill me.'

'Not yet,' she mumbled around me, the vibration of her words making me harder. 'I’m just getting started.'

Her hands weren’t idle either, sliding up to cup and massage my balls with a firm, knowing grip, coaxing every ounce of tension out of me. I could feel the pressure building, my breath coming in sharp pants as she worked me with ruthless skill. She was relentless, her mouth a hot, dripping haven, and I knew I wasn’t going to last much longer. My body was already sweating, my mind a haze of raw, horny desperation.

'Mia, I’m—' I started, but she cut me off with a fierce look, her lips tightening around me as she took me even deeper, her throat closing around my cock in a way that made my knees buckle. She wasn’t just taking me; she was claiming me, and I was powerless to stop the wave crashing over me.

The room spun as I teetered on the edge, her name a ragged moan on my lips. This was only the beginning, and I knew the night was about to get a whole lot wilder.
