In the sultry heat of Saltillo, Coahuila, two sisters, Tetona and her younger sibling, find themselves entwined in a web of unspoken longing. Their shared room, filled with the scent of jasmine from the open window, becomes their playground for secret desires. Tetona, her curves accentuated by the thin, damp fabric of her nightgown, can't help but notice her sister's growing curiosity. One evening, as they lie side by side, their legs brush, igniting a spark neither can deny. They begin to explore each other's bodies tentatively, their moans echoing softly in the night.
