Stepmommy's Little Product Tester

Serene hovers over a box of satin and plastic, adjusting straps and buckles with calm fingers. Keys rattle at the door and Kimmy steps inside, brow raised. She asks what her stepmother is doing. Serene turns slowly, smile already forming. She says she needs help first, then explains: her new erotic-product line is nearly ready, but every sample wants a live body before it ships. She wants Kimmy to be that body. Kimmy stares, cheeks hot, then nods fast enough to loosen her ponytail. The first item is see-through lace. Without warning Serene tugs Kimmy’s sweater over her head, unhooks her bra, slides the new set into place. Silk kisses warm skin. She pivots the girl this way and that—arms overhead, bent at the waist, knees on the sofa cushions—testing seams and stretch. Every tug of fabric pulls a small breath from Kimmy’s lips. Then the lingerie is gone again. Cool oil splashes across Kimmy’s bare shoulder, trails between her breasts, slicks down the arch of her back. Serene spreads it in slow circles, then sweeps a second scented blend along the inside of her thighs. Each fingertip lingers just long enough to count the flinches. Next come the toys. Serene starts with a sleek silver vibrator, gliding it across slick folds until Kimmy’s hips lift off the cushions. Then a thick glass dildo, eased inside inch by inch, twisting on the pull-out. Kimmy manages words between gasps: she prefers the vibrator’s relentless buzz, but the dildo’s weight feels fuller. Serene takes notes like a tailor taking measurements. Last is the strap-on. It sits heavy in her palm. She fixes the harness around her own hips and looks straight at Kimmy. Real conditions, she says, are the only way to judge. Kimmy swallows, heart thudding, then whispers yes. Serene steps forward, pressing the blunt head against slick heat, and the test begins in earnest—slow strokes building to a deeper rhythm, every thrust counted like a completed review.
