Tommy decided to go out to the shop and left me alone with his friend Dimitri. He had barely reached the car and I was on my knees with Dimitri's big cock in my mouth. I knew that I didn't have long and he could return in only a few minutes so I worked my magic, using my lips, tongue and throat and get exactly what I wanted. A mouthful of delicious cum from Tommy's friend! We didn't get caught and our secret was safe.
