Stepmommy's Little Product Tester

Serene's rummaging through a box when Kimmy walks in and asks what's up. Instead of answering, Serene goes straight for it—she needs a test subject for the erotic products she's trying to launch, and Kimmy's the lucky girl. Kimmy's too eager to please to say no. Serene starts with the lingerie, yanking Kimmy's regular clothes off and shoving her into some skimpy number. She turns Kimmy around, bends her over, makes her stretch out every which way. The fabric rides high, rubs tight, rides right up between her cheeks while she checks the stretch and support. Kimmy's tits are practically spilling out the sides. Then Serene peels the lingerie right back off like it never existed. She opens a bottle of massage oil and rubs it all over—down Kimmy's neck, across her tits, between her thighs, slow circles around her nipples, slick fingers sliding lower until she's completely glossy and glistening. Serene grabs the vibrator next, presses it to Kimmy's clit and watches her jump. She switches to the dildo, works it in deep, twists it, pulls it out just to see how slick Kimmy's getting. "Which one feels better?" she asks, like she's actually taking notes. Finally she holds up the strap-on and says the real test is how it feels in actual use. She wants to fuck Kimmy with it—nothing clinical, just straight-up fucking so they can judge the harness, the angle, the whole setup under real pressure. Kimmy stares at her, half-shocked, half-soaked, and nods yes before she can even think twice.
