Two Brazilian teens, Paulo and Maria, explore their budding sexuality in the privacy of Paulo's room. Paulo, a curious young man, discovers the pleasure of masturbation, his fist pumping his virgin cock, the foreskin gliding back and forth. Maria, intrigued, watches from the doorway, her heart racing as she witnesses her brother's intimate act. Seizing the moment, she joins him, her small hand wrapping around his thick shaft, guiding him to his first orgasm. Their secret moments of pleasure grow bolder, their bodies entwined in a dance of discovery.
