Last year my father went to jail and I met his long-time friend in a visit I've made to my father. We started to go out and I end up living with him. A few months ago my father was released and he came to live with us until he finds his own place. What I didn't know was that since they were friends they had a pact, they liked to share their women with each other and I was convinced to participate in a threesome with my father.
