My sister stayed with me while her husband was on a business trip. She is talking to him on the phone and he says he is on his way to pick her up and he will be there in 10 minutes. She hangs up and asks me if I can cum in her in under 10 minutes. She starts to suck my cock and then she sits on my cock and rides me. We are listening for his car the whole time. I turn her around and fuck her doggystyle until I squirt all of my cum in her pussy! As I am pulling out, I hear a car door, it is him, we made it just in time
