Best friends since childhood, Ana and Maria, now teenagers, share a secret only they know. They've never been with a man, but they've explored each other's bodies in the dark of night. One evening, Ana suggests they take it further, guiding Maria's inexperienced hands to her breasts, teaching her how to touch, how to pleasure. They undress each other, their breaths ragged with anticipation, and Ana shows Maria how to taste her, how to lick and suck until Ana cries out in ecstasy. Maria watches, learning, and when Ana returns the favor, Maria discovers her own pleasure, their bodies entwined in their shared secret.
