Isabel, the nuera, finds herself alone in her suegro's house, her mind filled with thoughts she can't suppress. She starts to touch herself, her fingers tracing the lace of her panties, feeling the dampness that's already gathering.

She pushes her fingers inside, mimicking the rhythm her husband uses, her moans filling the silent house as she chases her release.
