My older half-brother is at college and some times likes to make us a surprise visit. I live with my Mom since she got divorced from my Dad and really enjoy when my big brother comes to visit us. He never stays long but we always have the time to have a good fuck. This time he just showed up and I was alone at home, but we got so horny that even knowing our Mom could come home any minute, we risk it. That's why we did it close to the window, so we could see her car on the road and give us more time, and don't be caught.
