I was supposed to be building a good relationship with my new sister-in-law, talking to her about school and love, but...!? One day, my girlfriend dumped me, and the reason was that I couldn't have sex because of my huge dick. My sister-in-law comforted me when I was feeling down, but she told me that she would watch over me when I felt that I would never be able to have sex again. My sister-in-law couldn't stay still when I saw my dick, which was bigger than she had imagined, and she suddenly started giving me a blowjob! My pussy was throbbing in front of my big dick and I couldn't stand it!
