I was fucking the Doctor Space Cowgirl then I turn around and ride him reverse Space Cowgirl bouncing hard up and down on his cock then I lay him back and start sucking on his cock I feel he is ready to cum so I squeeze hard on his balls and suck hard and he soon reaches a climax and shoots his full load deep in my mouth, I now have a sample of Earth Mans sperm to take back to my planet so I no longer have need of the Doctor so I grab my ray gun and Disintegrate him.Speedybee xxx
