I asked my younger brother's girlfriend out on a date without telling her. She looked cute and sexy, so I thought I'd be lucky if I could have sex with her once, and she agreed. It seemed like she had a date with her younger brother in the evening, so I went out with her for a quick date to warm her up, and then I forced her into a hotel room, thinking we still had time... and she got more and more lewd. It was almost time for the date, but I changed the time for my date with my younger brother, and we went back to the hotel and had raw sex again.
