Hot sex with a university girlfriend

My stepfather punished me for being 15 minutes late in the evening after a walk with friends, took away my phone and no one could contact me. A friend came to visit me and find out why I did not answer. And so I told him what a jerk my father is and that I want to take revenge on him. And I told him to come over because I had a plan. He asked me what I had in mind and I told him that we should sleep together. To piss off my father.
