Unbeknownst to their parents, two innocent 18-year-olds, Emma and Lily, find themselves alone in the house. Boredom leads them to explore each other's bodies, tentatively touching and caressing. Emma's inexperienced fingers trace Lily's soft lips, making her gasp. Lily, equally inexperienced, explores Emma's firm breasts, her nipples hardening at the touch. They take their time, learning each other's bodies, their innocence making their exploration all the more erotic.
