Я позволила моему отчиму трахнуть меня, чтобы он не говорил на меня мачехе

I was on a video call with my boyfriend and stepfather came into my room, I was surprised and I lied to him telling him that I was talking to my friend, he left and then returned to my room, he had recorded me masturbating by video call and I had no choice so we had hard sex so that he wouldn't give me away to my mom, since she doesn't know that I have a boyfriend.
