In the throes of puberty, a brother and sister discover each other's bodies, their inexperience fueling their intense curiosity. As they tentatively touch and explore, their innocence gives way to raw desire. The sister's soft moans as she touches herself drive her brother wild, and he can't help but stroke his growing erection. Their first time is clumsy and passionate, a dance of discovery as they learn each other's bodies and the power of their forbidden desire.
