Невинность или провокация? Ct 8

A stepfather on vacation relaxed at home exchanging messages with his lover, and a stepdaughter in her prime with great energy and completely bored! There are moments when she behaves in an incomprehensible way, insinuating attitudes that refer to both innocence and provocation towards her stepfather. This behavior has awakened in the stepfather a certain distrust and lust for his stepdaughter, to the point that he even remembers her when he is having sex with his lover!
