In the dimly lit room, the scent of essential oils hangs heavy. Jillene, kneading her stepbrother's tense muscles, feels an unexpected spark. His groans morph from pain to pleasure as her hands linger on his lower back, tracing the edge of his boxers. She can't help but imagine his cock hardening under her touch. He flips over, catching her gaze, and she blushes, realizing her nipples are taut beneath her silk robe. Their breath hitches as she straddles him, grinding slowly, their bodies slick with oil and desire.
