The Science Experiment

The girl clamps the pads to her forehead, taps more commands, nothing. Frustration prickles under her skin until the sensors slip and land in her lap. She tries again lower, right over the thin cotton, and the jolt hits fast—sharp, grinding, her hips jerking before she even knows she’s coming. Hard, loud, soaking. Mona heard everything. She waits, then slips inside once the shower starts running, straps the electrodes low, and the shock slams through her so thick she nearly bites her own lip bloody. Steam hisses when Cadence opens the door and sees her stepmother on the bed, electrodes glowing between spread thighs. Mona doesn’t blink. “Show me,” she says, voice low, daring. The towel drops. Mona places the sticky circles herself, one on each puffy lip, then hits the switch. Cadence’s knees buckle at once. Mona’s tongue follows—slow circles on her swollen clit while electricity hums straight through her cunt. Every time Cadence thinks she’s done, the current spikes again, milking another orgasm out of her until her thighs shake and her breath breaks. The older woman wants more. She lies back, pads snug against her own soaked slit, and nods. Cadence climbs between her legs, drives two fingers deep, curling until Mona sprays across the sheets in one long, filthy gush. Rules are gone. Cadence climbs higher, plants her dripping pussy on Mona’s mouth, grinds until the tongue drags her over the edge again. Then she dips lower, tongue flicking Mona’s tight rim, working it until Mona comes loud enough to rattle the frame. Later the electrodes ride with them, slapping skin as they trib hard—wet lips sliding, current humming between them. They finish the night grinding and shaking, electrodes flashing with every fresh, helpless climax.
