Under the same roof, a brother and sister, bored and restless, retreat to their private spaces. She strokes her clit, imagining his touch, while he jerks off, thinking of her curves.

Naked and vulnerable, they explore each other's bodies, their fingers and mouths replacing their secret fantasies. Just as they're about to seal their newfound intimacy, reality intervenes, leaving them breathless and yearning.
