Chapter 3: Home Alone

As we approached civilization, I instinctively pulled away from him, the dreadful thought of streetlights exposing us making me shiver. Sweat glistened on my skin, betraying the secret passion we had shared just moments ago.

Pulling into the driveway, I locked eyes with Matti. His face was flushed, his lips still stained with a faint pink, glistening with the taste of me. I couldn’t hold his gaze for long—the embarrassment, the rush of nerves forcing me to look away as the car rattled over the gravel.

As the car stopped, I scanned myself for any sign of our encounter, wiping my lips with my wrist and adjusting my bikini like the good girl I was supposed to be. But I didn’t feel like a good girl.

I felt as if I was floating to the house, the atmosphere was surreal, I felt as though something had changed, it felt like I was a visitor in a memory. Shaking my head, I focused on the pounding of my heart, grounding myself as I watched my parents put on evening coats.

Matti had already disappeared into his room while I lounged on the sofa, letting the cool leather soothe my overheated body. My mom grinned at me as Dad pulled her by the waist, “Honey, me and your father are going out for drinks. You’ll be okay alone, right?” She giggled as they moved toward the door.

I was still so flustered from the car ride that I could barely piece together a response. “Uh ... yeah. We’ll be fine.” It took a moment for the implications to hit me—home alone. With Matti.

“Good girl. I left some money on the counter if you two want to order a pizza. Don’t wait up!” Mom laughed again, and before I knew it, the door slammed shut. I found myself standing before the lock had even finished clicking into place.

My heart raced, my feet practically floated down the hallway. I could hear Matti shuffling around in his room, his door slightly ajar. My hand hovered near the cold metal handle, my thoughts a chaotic swirl of guilt and desire. Could I even face him?

I decided against it, I should think carefully before taking things further. I wanted to tease him, make him squirm a little, I saw the way he looked at me. The way he would “brush up against me” when he passed, the way his gaze lingered on me a little longer than it should have during family movie night. It made me giggle, I wanted to see how far I could push him, give him a taste of what he desired so much and watch him buckle. I never thought it would lead to this. Now though, standing outside his door, it wasn’t just him who was trembling with need. It was me.

What happened to me?

I pulled my hand away from the door and turned to leave, thinking I’d cool off in the shower. But as I stepped back, the cool draft of the A/C kissed my skin, and the door creaked open

Matti stood there, frozen. His eyes locked on mine, and for a moment, everything stopped. The only sound was the frantic beating of my heart in the stillness.

“I...” I stammered, unable to look away. I wanted to flee, to pretend nothing had happened, but I couldn’t. My body ached for him to close the distance.

“They ... um ... they went out,” I mumbled, my voice low and breathless, laced with all the unspoken things I couldn’t say out loud.

“I know,” he whispered, his breath ragged, his chest rising and falling with each sharp inhale. His hand shot out, grabbing my wrist, and the touch sent a shiver through me. It felt like the world held its breath as he pulled me inside, shutting the door with a thud that seemed to reverberate in the silence.

My back pressed against the door, the wood cool against my overheated skin. Matti stood so close I could feel the warmth radiating from his body, the heat of him enveloping me, suffocating and irresistible.

His fingers tightened on my wrist, his grip possessive, trembling with barely-contained restraint. His breath ghosted across my neck, each exhale sending jolts of electricity straight through me. My chest rose and fell in time with his, the space between us shrinking to nothing.

He didn’t speak. He didn’t have to. The look in his eyes, visceral and unrestrained, said everything. His need mirrored mine—raw, feral, undeniable.

I wanted to say something, to break the silence, but words wouldn’t come. Instead, I arched toward him, my body betraying every ounce of guilt that still clawed at me. His lips hovered near mine, close enough to taste the breath between us, but he didn’t kiss me. Not yet.

“You knew what you were doing.” His voice broke the silence as I watched his lips, still swollen from our kiss. “At the beach—you wanted this, didn’t you? You planned it?” His tone was teasing, but I knew he was trying to justify it to himself—our unholy act, the way we touched each other.

“What if Mum and Dad had seen us?” His voice wavered, but I cut him off before he could finish.

“Then why didn’t you stop me?” I took a step forward, my breasts pressing into his chest, my hard nipples brushing against his torso like sparks igniting a fuse. “You didn’t stop me because you liked it. You liked touching your sister while Mum and Dad looked the other way.” My voice softened into something darker, daring. “And you let me do all those things to you in the car.”

His chest shuddered beneath my palm as I placed it over his heart, feeling the frantic beating. “They aren’t home now,” I whispered, my words a challenge. “So what are we going to do?”

His breath hitched, and he stumbled back onto the bed. The mattress dipped beneath him, his forearms flexing as he leaned back, supporting his weight. His eyes, dark with lust and guilt, watched me as I stepped forward, the damp fabric of my bikini clinging to my skin, the last thing separating us.

“Take them off,” I whispered, my hips swaying inches from his face. His gaze flickered with temptation and hesitation.

“Please,” I begged, my voice softening as my confidence wavered. “I want you to see.”

His trembling hands moved hesitantly to my hips, the touch of his fingers against my sun-kissed skin felt disarming. I looked down intently as his finger wrapped around the soft straps and begin shedding the last barrier of decency we still had.

His breath hitched as he leaned in closer to get my panties past my ankles, I felt the heat of his breath on my exposed flesh, it felt electric, searing my skin.

I was lost in the animalistic delirium of this moment and reached down to pull of his shorts. My hands grasped the pockets and pulled backwards, making him fall back onto the bed.

He gasped as I pulled them past his ankles, I looked up to see his cock slowly rising in rhythm with his pulse, standing enticingly, spurring me to action.

“Wait...” The whisper escaped his lips, a lie, he didn’t want to wait.

I pushed my knees onto the soft bed, straddling his thighs as my hands desperately pulled at the straps of bikini freeing my soft breasts. His cock throbbed between my legs, the hot shaft pressing into my slick heat, pushing against my belly, almost reaching my belly button. I felt a bit of unease seeing how far inside me it could end up.

I squeezed it between my thighs holding it in place as he writhed and squirmed under me in protest. I could feel the heat radiating from it warming my pussy. I marvelled at the pink tip, slick with precum. It looked delicious. My own brother has been keeping this a secret from me for so long.
