Mari, a raven-haired beauty, is caught off guard when Anne, her stepsister, enters their shared bathroom, clad only in a towel. Mari's eyes widen as Anne drops her towel, revealing her naked body. Anne, emboldened by Mari's gaze, reaches out, tracing Mari's jawline, her fingers lingering on Mari's full lips. Mari's breath quickens, her body betraying her as Anne's fingers slip into her mouth, sucking gently. Anne's other hand reaches down, cupping Mari's mound over her shorts, feeling the heat and wetness. Mari moans, her hips pressing into Anne's hand, as Anne's fingers slip beneath the fabric, finding Mari's clit, rubbing in slow, deliberate circles.
