Riley Daniels, my step-sister, bought me a gift for Christmas. I had nothing for her, and our parents weren't home. She was walking around in her underwear, which made me feel horrible but also drawn to her. I begged her to get a drink of water while I went to get the gift I had for her out of desperation. After frantically searching the entire house for something to gift her, I had an epiphany. I slipped my penis into a present box and gave it to her. We finally sat down again, and although she was ecstatic to open it, she was also very nervous. I informed her that I was aware of her penchant for fucking, so I thought it would be the ideal present. She thought of our old games together. She agreed and proceeded to suck, ride, and spray till I filled her with sperm.
