Sin Bound: short story collection

[ EUNICE ]

I stood in front of my stepbrother’s room, watching him work out. The muscles in his arms flexed effortlessly as he lifted weights, and I couldn't take my eyes off his biceps and abs. He looked breathtakingly beautiful. If he weren't my stepbrother, I would have devoured him right then and there. A sharp ache throbbed deep between my legs, and I could feel myself growing completely soaked just from watching him.

Suddenly, his eyes flicked toward the door. Panic shot through me. I bolted back to my room, slamming the door shut behind me.

Oh my God, he almost caught me staring.

But the rush of adrenaline only fed the fire. The urge was entirely too strong, and I needed relief. Without a second thought, I went to my nightstand drawer, pulled out my vibrator, and threw myself onto the bed, hastily pulling down my panties.

The moment the vibe touched my skin, I gasped. The sensation was incredible. Before I could stop myself, I was loudly moaning his name into the empty room. I pressed the vibrator harder against my skin, my hips tilting up to meet the rhythm. Every vibration sent a wave of heat straight to my core, but my mind was still stuck in the hallway. I closed my eyes, picturing the way his biceps flexed, the sweat glistening on his chest, and the intense look in his eyes right before I ran.

The fantasy made everything twice as intense. My breathing grew shallower, and my voice hitched as another loud moan slipped past my lips. I couldn't bring myself to care how loud I was being anymore; I was too far gone.

"Please," I whimpered to the empty room, arching my back as the tension built to a tight, unbearable peak.

Right as I was about to crash over the edge, the door suddenly clicked and swung open.

“What are you doing?”

I froze, completely paralyzed. My stepbrother stood in the doorway, his chest still heaving from his workout, his eyes locking instantly onto my exposed body. My legs were spread, and I was dripping so heavily from my own juice that there was no hiding it.

"Nothing," I gasped out, scrambling to pull the covers over myself to cover up.

"Don’t even try it," he said, his voice dropping an octave as he walked straight into the room, shutting the door firmly behind him. He stepped closer to the edge of the bed, his gaze burning into me. "You mean to tell me it’s nothing, and you’re in here loudly moaning my name?"

"It’s... it’s..." I began to stutter, the vibrator still clutched in my trembling hand. My thumb fumbled blindly against the plastic until I finally hit the button. The sudden silence in the room was deafening, except for the sound of my own ragged breathing and the frantic pounding of my heart.

"Show me," he rasped, stepping close enough that I could feel the heat radiating off his skin.

"What?" I whispered, my heart hammering against my ribs.

"Show me your sinful pussy," he demanded, his eyes dark with a sudden, predatory intensity.

My breath caught in my throat. The sheer shock of his words sent a fresh jolt of electricity straight to my core. I looked up at him, searching his face for any sign that he was joking, but his expression was completely serious, heavy with a raw desire that mirrored my own. The taboo of the moment made the ache between my thighs intensify until it was almost painful.

Slowly, my trembling fingers let go of the blanket. I pulled it back, exposing my flushed, trembling body to his intense gaze once more. I parted my thighs slightly, completely exposed, glistening and entirely undone by him.

He swallowed hard, his jaw clenching as he took in the sight. He didn't hesitate anymore. He reached down, his large, warm hand gripping my knee to push my leg further apart, settling himself onto the edge of the mattress.

"You've been watching me," he murmured, his voice a low growl as his fingers brushed against the inside of my thigh, sending a shiver straight up my spine. "Now it's my turn to watch you finish."

His fingers migrated higher, the heat of his palm branding my sensitive skin. I couldn't stop the soft whimpering sigh that escaped my lips as his touch edged closer and closer to where the ache was loudest.

"Look at me," he commanded softly, his voice thick with an intensity that made my core pulse in response.

I forced my eyes open, locking my gaze with his. His eyes were incredibly dark, reflecting a hunger that completely obliterated any lingering sense of hesitation or regret. The sheer taboo of what we were doing hung heavy in the air, making every breath feel thick and charged.

"You were making so much noise," he murmured, his thumb finally brushing against the very edge of my soaked center. I gasped, my hips instinctively jerking upward at the contact. He let out a low growl of approval. "Is this what you wanted when you were peeking through my door?"

"Yes," I confessed in a breathless whisper, past the point of trying to deny it. "Please..."

"Show me how you do it," he rasped, his hand sliding down to grip my hip, anchoring me in place. "Use the vibe. Let me watch."

My hands were shaking so badly I could barely find the power button under the pillow. When I finally clicked it back on, the familiar, low hum filled the space between us. With his eyes tracking my every move, I brought the device down, pressing the vibrating tip directly against my swollen clit.

A loud, uninhibited moan tore from my throat. My back arched off the mattress as a violent wave of pleasure ripped through me. Watching him watch me was entirely too much; the visual of his broad chest, still slick with sweat from his workout, combined with the friction of the toy, pushed me dangerously close to the brink instantly.

"Don't close your eyes," he ordered, his grip on my hip tightening as he leaned over me, his scent completely enveloping my senses. "Keep them on me."

I stared up at him, my vision blurring slightly as the tension coiled tighter and tighter. I began to move my hips in a frantic, desperate rhythm, chasing the release that was just out of reach. He reached down with his free hand, his long fingers dipping into my slick warmth, spreading my fluids over my skin and heightening the friction until it was almost overwhelming.

"You're so wet for me," he muttered, his jaw clenching as he watched my face contort with pleasure. "Come on. Come for me."

That was the breaking point. Hearing those words slip from his lips shattered whatever control I had left. My body tightened into a hard knot, and with one final, desperate press of the vibrator, I spilled over the edge.

A sharp cry left my lips as my walls clamped down in a powerful, rhythmic climax. My hips buckled against his hand, and I completely lost myself to the waves of heat crashing through my lower half. He didn't look away for a single second, absorbing every tremor and every breathless sob of relief that escaped me.

As the intensity slowly began to recede, leaving me shivering and completely spent, the hum of the vibrator was the only sound left in the room. He slowly withdrew his hand, his fingers glistening, before his gaze drifted back up to my flushed, exhausted face. A dark, satisfied smile touched his lips.

"Good girl," he whispered, leaning down until his lips were brushing against the shell of my ear. "Next time, don't hide behind the door."
