"My sister asked me to come to her room later. When I did I found her as you see her. She asked me to come in and close the door. I walked in slowly and ask her what she was doing with the pentagram. I almost ran out of the room when she said she was trying to appease the great deity of chaos, when she said she'd offer him the virginity of a far maiden. My attitude changed when I said okay sis. Turns out cult girls are crazy in the sack especially when they try to appease their god. If you had asked me before if there was mystical forces I would have disagreed, but in that pentagram, something came over me as I repeatedly emptied my balls in my sister as she begged for forgiveness."
