💜 Devoured 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 aching as the tight bindings dug into my skin. The filthy mattress beneath me offered no comfort, but that was the least of my worries. My heart raced, and panic surged through me with every shallow breath I took. The whip around my neck felt like it was cutting off more than just air-it was slicing away my sense of reality. How did things get this far?

Amethyst straddled me, her weight heavy on my hips, her wild eyes fixated on mine. But it wasn't her, not the Amethyst I knew. Not the goofy friend I always had by my side. But then again it is my fault that I've always seen her as just a friend right?

There was no trace of her left-just a crazed, twisted obsession staring down at me. I could still feel the sting of pain from my ankle, where her whip struck me earlier, and it sent waves of nausea through my body. It wasn't just the physical hurt though. It was the realization that the person I trusted, the person I thought would always have my back, had snapped.

As she looks at me with those unhinged eyes, I see a cruel smile spread across her face. She reaches up with one hand and strokes my cheek, her fingers rough and calloused.

"You should have noticed me sooner, Y/N," she coos, her voice dripping with malice. "Should have realized I loved you more than anyone else. But now you're mine, all mine." She leans down, her lips brushing against mine in a sickeningly sweet kiss. I try to turn my head away, but the whip around my neck tightens, forcing me to submit to her disgusting affection.

She pulls back, her breath heavy and labored. She reaches behind her and grabs another whip, cracking it loudly in the small, dim room.

I flinch at the sound, my heart pounding in my chest. She brings the whip down hard across my chest, the leather striking my skin with a vicious crack.

I scream, tears pricking at the corners of my eyes as the pain shoots through me. "You're going to learn to love me, Y/N," she hisses, her voice echoing in my ears. "You're going to worship me, and you're going to do it gladly." She brings the whip down again, and again, each strike leaving angry red welts on my torso.

Finally...after a painful couple of minutes, Amethyst finishes her whipping, I watch in horror as she stares at the fresh blood oozing from the wounds, her eyes gleaming with a perverse fascination. She sticks out her tongue and traces the welts, tasting my blood with a sadistic relish.

The coppery flavor only seems to arouse her further, her cheeks flushing a deep crimson as she listens to my screams and struggles.

"Mmm, you taste so good, Y/N," she murmurs, her voice dripping with hunger. She reaches between her legs, rubbing her cloth-covered crotch against my hip as she grinds forward and backward, the fabric of her outfit growing damp with her arousal.

I can feel the warmth and wetness seeping through the material, my mind reeling at the realization that my once innocent friend is getting turned on by my pain and suffering.

"Since I'm a gem, I've never really understood human pleasure..." she admits, her voice trembling with a mixture of confusion and excitement.

"But being with you, feeling your struggles and screams, it's making me curious. I want to know what it's like to be intimate with you, to feel your body against mine." She presses her soaked crotch against my thigh, the heat and moisture unmistakable as she continues to grind against me.
