💜 Bound by Desire 💜

[Just a fair warning, if your not really into bdsm the following sex scene is pretty intense, I'll still include gifs but..damn even I was squeamish as I made this. Enjoy I guess?]

Y/N's Pov

I groaned, my wrists screaming as the coarse rope sawed into my flesh. The stench of mildew and sweat clung to the filthy mattress beneath me, the springs digging into my back like jagged teeth. Every ragged breath came harder than the last, the whip’s leather coil biting into my throat until black spots danced in my vision. How the fuck did I end up here?

Amethyst’s weight crushed my hips, her thighs clamping around me like a vice. Her eyes—God, her eyes—weren’t the warm violet I remembered. They were black pits, dilated with something feral, her pupils swallowing the light whole. This wasn’t the girl who’d shared shitty fast food with me at 3 AM. This wasn’t even a person. Just hunger. Just ownership.

The welt on my ankle throbbed, the skin split where her whip had lashed me earlier. Nausea twisted my stomach, but worse was the knowing. The way her fingers had lingered too long when she’d “accidentally” brushed against me before. The jokes about us being “meant to be” that I’d laughed off. Fuck. Fuck, I should’ve seen this coming.

Her calloused palm scraped against my cheek, the touch mocking in its gentleness. “You should’ve noticed me sooner, Y/N.” Her voice was syrup and razors, sticky-sweet. “Should’ve realized I loved you more than anyone else.” When she leaned down, her breath reeked of mint and something sour—adrenaline, desperation. I jerked my face away, but the whip yanked my head back, the leather creaking as it choked my gasp into a whimper.

Her lips smashed against mine, teeth clipping my bottom lip until copper flooded my mouth. She moaned into it, her tongue shoving past my clenched teeth like she was digging for secrets. One hand fisted in my hair, the other groping down my chest, nails carving half-moons into my ribs. This isn’t happening. But the pain was real. The wet heat between her thighs grinding against mine was real.

She broke the kiss with a string of saliva connecting us, her grin curling like a predator with its jaws already locked. “Now you’re mine,” she panted, her fingers already tugging at the waistband of my pants. “All. Mine.”

She pulled back, chest heaving, her breath coming in ragged gasps as if she’d just run a mile. The second whip uncoiled from behind her like a serpent, the crack of leather splitting the air before it even struck. I flinched, my body tensing—but there was nowhere to run.

The first lash came down with a sickening snap, splitting skin like overripe fruit. Fire erupted across my chest, my scream tearing free before I could choke it back. Tears blurred my vision, but I saw her—lips parted, pupils blown, watching me writhe like it was the most beautiful thing she’d ever seen. "You’re going to learn to love me, Y/N," she hissed. The whip rose again. "You’re going to worship me." Another strike. Another scream. Over and over, until my voice cracked and my torso was a canvas of raw, weeping stripes.

When she finally stopped, the silence was worse. Blood welled along the welts, droplets rolling down my ribs. Amethyst licked her lips, then dragged her tongue along the deepest wound. The groan that left her was obscene. "Mmm… you taste so good." Her hips jerked against mine, the damp fabric of her shorts clinging to her cunt as she ground down, leaving a slick smear on my hip. My stomach turned. She’s wet. From this.

Her fingers dug into my thighs as she rutted against me, her breath coming in short, desperate bursts. "Since I’m a gem… I’ve never really understood human pleasure," she admitted, voice trembling. A laugh bubbled up—hysterical, giddy. "But fuck, the way you scream? The way your blood tastes?" She rocked harder, her clit rubbing against my thigh through the soaked fabric. "I need to know what it’s like inside you. Need to feel you."
