The alarm clock cut through my sleep like a jagged blade, jolting me awake to the reality I’ve crafted for myself the previous night. The sun from the window beat down on my forehead, the searing Mediterranean heat making a bead of sweat drip down to my brow.
There was a knot in my stomach, the pent up anxiety relentlessly gnawing at my frayed conscience. Yet, it couldn’t mask the excitement, I wanted to see what corruption the day held in store for me, how close to the sun could I fly, how I could make Matti squirm.
As I pulled the covers off to leap out of bed, I realised how wet I’ve gotten just from the anticipation of the day. I admired the wet spot on my panties, a testament to my unbridled reckless desire. It was devious but the forbidden fruit was just too sweet and knowing Matti couldn’t resist my temptation pulled me deeper into this abyss.
After a quick morning shower I threw on whatever I could find on the floor next to my messy suitcase, a creased crop-top and a pair of shorts. The way the shorts clung to me was almost indecent, perfect for what I had in mind.
I was invigorated as I reached the kitchen, a scene of domestic bliss contrasting with the wicked thoughts in my mind. Mom humming as she laid out fruits and brewed a pot of coffee, Matti sitting next to dad, looking at the mapped out day they planned for us. It seemed so normal, so-much-so that I felt like an outsider looking in.
I had to maintain this veil of innocence, ignoring the unquenchable lust clawing the remnants of my purity. There was a hint of guilt as I looked at my family there, unaware of the transgressions which happened right under their nose. However, we were in too deep, there was no repentance for what we did, so why not continue?
“Coffee, sweetie?” I was jerked back into reality with my mom’s comforting voice. Matti’s eyes darted to me with a startled look. I smiled at him, offering a kindred understanding of our situation and the entanglement we felt.
“Y ... yea, I need it, thanks.” My eyes crinkled with a smile as I dropped myself onto he chair next to Matti, pulling a mug close. I could feel his tension and I relished it. Each time the hot air carried his scent to me I felt an electric tug. My body reacting on its own.
The conversation around me became muffled as I focused on my own twitching leg, slowly moving outward, my legs parting. I looked to the side, catching Matti’s gaze, holding it as I let my knee brush against his. I had to stifle a whimper as the heat of his skin met mine—his muscles against my softness. He didn’t pull away, we sat at the table silently, listening to our parent’s idle chitchat, completely lost in the illicit sensation of our flesh—this isn’t how a sister is supposed to touch her brother.
I felt a strange thrill, doing this in the daylight, if they looked they’d see how my thigh caresses his, the fervour in our shuddering movements, yet they were blind to it as we strayed so close to the edge.
As mom poured the fragrant black liquid into my mug, I turned to her, my hot breath escaping with a fevered rasp, “What was that about the market yesterday?” I could barely get the words out.
“We’re going to the open market in the town today.” Her smile was disarming, but my mind was fixated on my desires. A gnawing at my core, desperate to be alone with Matti again.
“Sounds like fun, I need some new clothes ... something sexier.” I joked with my mom, her light giggle putting me at ease, unaware of the implications.
“Oh? You trying to show off for a new boyfriend, dear?” She quizzed me while ruffling my hair.
“Hah! Not quite, but who knows ... maybe I’ll meet a hot Greek guy while I’m here.” I felt Matti’s leg push harder into mine, his eyes darting to my face as I ignored him—he was so easy to tease.
“Well, good luck, dear.” My mom chuckled as she pulled away to sit down herself.
Under the table I felt another heat approaching. My stomach tensed and a sudden whimper escaped my lips as I felt Matti’s hand descend onto my thigh, his fingers grabbing and clenching my flesh possessively, leaving a red mark of his affection on my skin. I looked over at him with burning eyes. This is what I wanted.
As the morning progressed we packed the car. The heat was overbearing, dry and accented with the fragrance of dried vegetation and the sea, a paradise. I couldn’t help but to feel like this was a bubble, an escape from my real life, or perhaps my guilty conscience just needed to create this duality.
To my dismay, Matti sat up-front with dad, discussing the map and the day ahead. I sat with mom, looking at pictures of nearby beaches and restaurants in the area, talking about her favourite wines. On any other day I would be absorbed in the conversation and atmosphere like a good daughter, but today there was something darker on my mind.
The market bustled with life, colourful stall and lively conversation, stray cats hoping to get lucky. The smells of fresh food mixed with the smell of the sea to create a vibrant atmosphere. We weaved through the crowds, looking for anything that caught our eye, souvenirs, clothes, snacks, it was almost too much to process.
Then, a man approached my mom, a stereotypical moustachioed seller.
“Pretty ladies! Come! Come! You need better clothes for this heat, yes?” His accent was thick as he waved his hand, inviting us into his makeshift tent store. The walls lined with colourful beachwear, the smell of factory-fresh fabric.
“Maybe you can get something here?” My mom nudged me as we entered. I shot Matti a quick glance, his eyes briefly fixed on mine.
Inside, the man was in his element, laying out bikinis, sundresses, letting me and mom pour over them. I could see dad outside in the sun, taking pictures, lost in his own little world, but behind me I felt the unmistakable presence of Matti. He stood right behind me, and my eyes twinkled with delicious opportunity.
I leaned forward, feigning interest in a yellow sundress, my back arching, my ass moving back just enough to graze against Matti’s crotch. I could feel him move back slightly, scanning his surroundings for prying eyes, but I was unrepentant. I shifted lower, moving back further. I felt the soft flesh of my ass press against his hips, separated from our desire but two layers of clothing, the fabric electric against my needy skin.
It was almost maddening, feeling his swelling length nestled between my buttocks. I held back the wicked purr threatening to escape my flushed lips. And just then a wicked idea began brewing in my mind, my heart pounded at the mere thought.
“I think I’ll try this one on.” I picked up the yellow sundress, draping the sheer fabric over my hands as I stood up, pulling back from the comfort of Matti’s touch. The absence of his warmth stoking the embers I felt deep in my core.
“Great choice! You will look beautiful!” The seller smiled widely, his moustache tickling his own nose. He pointed me towards the changing room in the corner, a small stall with a black curtain—all I needed.
“Go on, dear, I’ll go check on your father.” My mom announced as she turned on her heel towards the exit. I almost trembled with anticipation and anxiety, I knew what I needed to do and I just needed everyone to look away for a single moment.
I tugged Matti’s wrist, pulling him close to the changing room, he stumbled slightly behind me.
“What are you do doing? Ouch!” His protests fell on deaf ears. I looked around the small, dark store. Our mom turned away, the seller lost in his phone, scrolling. I pushed Matti into the changing room, following closely behind and closing the curtain.
As soon as the curtain pulled shut on our little sanctuary, an Eden in the sea of people, I felt an elation bubbling up in my stomach. The twisted thrill of being stuck in this trap with my brother.
“Shhh, be quiet, Matti.” I pushed my finger against his warm lips, savouring their softness. The changing room was silent apart from the pounding of our hearts, the smell of sweat stoked by the fear of being discovered. It all heightened the sensation to unbearable levels.
I looked down at the cramped space. Barely enough to move around each other, I relished the closeness, out hips pressed together, unable to separate, sharing our heat. For a moment I was lost in the sight, his shirt clinging to his toned body, sleeves tight around his upper arms, but I knew we didn’t have much time, and I needed to take what I wanted.
