Faced with that overly erotic naked body, I lost my mind and could no longer restrain myself. That night, I attacked her while she was asleep and ejaculated inside her multiple times… At first, my sister was furious, but after being brought to multiple orgasms by her brother's youthful and intense lust, she unknowingly became a prisoner of the immoral pleasure! From using dildos and vibrators for toy training to secretly having sex in various parts of the house behind our parents' backs, the two of them gradually became addicted to crossing the taboo line, and their forbidden sibling life began!
