Two words: Uncontrollable Orgasms

Rain stays locked in place, hips pinned, arms and legs stretched until her shoulders burn. A vibe sits dead on her clit, no slack, no mercy. It rips the first orgasm out fast and loud, then drags a second right on top before the first even fades. Each new climax hits harder. Her thighs shake, her voice cracks, but the wand stays glued until her eyes go glassy and her mouth spills raw nonsense. They flog her chest first, the heavy falls snapping across tight-clamped nipples, then drop the lashes lower until her swollen pussy is slick and stinging. The pain spikes straight into the next orgasm, turning screams into broken babble. She goes silent mid-thrash. Eyes open, unfocused, body still twitching under the relentless buzz. Checked out. Gone. Only the vibrator and the slick sound of her cunt keep any rhythm while the rest of her stays quiet and still.
