A voyeuristic 'gostosa' catches a glimpse of her neighbor, a soloboy, in the throes of self-pleasure. Her heart races as she watches him, his hand moving rhythmically along his thick, veiny shaft. She can't help but imagine it's her hand, her touch, making him groan in ecstasy. Her own body responds, her nipples hardening, her pussy throbbing. She bites her lip, her hand creeping down her body, ready to join him in his solitary, yet shared, pleasure.
