In the throes of puberty, two siblings, isolated and curious, find themselves drawn to the unspoken tension between them. The girl, a virgin, explores her budding sexuality in secret, while her brother, equally inexperienced, can't help but notice her subtle changes. One day, their shared bathroom becomes the backdrop for their first intimate encounter. She's in the shower, he's in a hurry, and their eyes meet as she's suddenly exposed. Awkwardness turns to desire, and they tentatively explore each other's bodies, learning the art of touch and pleasure. This forbidden first time is a dance of innocence and sin, leaving them breathless and craving more.
