Remix: Soaring High (The Rusted Wingspan Remix) [Mal/River, 100 words, rated R], by jedibuttercup
Arousal works its way up River's spine in shuddering waves, speeding her heart and drawing lids low over her eyes, but her hands remain steady.
Long strokes of tongue; quick jabs; lingering applications of labia oris to labia majora. Her world has narrowed to just this: the yoke in her hands, pure focused pleasure between her thighs drowning out all other noise.
Her brother worries, thinks that flying-- thinks that sex is beyond her; but for all the smooth, unscarred shapes his skin and Kaylee's make together, he will never comprehend.
This is the closest she ever comes to serenity.
