My wife once blew me in the car. If I left the story at that it wouldnt be all that uncommon. I will be more specific.

She blew me in the back seat of the car, while my parents were in the front seat. Dad was asleep, and mom was driving. On top of that it was dark, so they did not know what was going on.

She did not let me cum, at that point she was not comfortable swallowing and we didnt have a bottle or anything for her to spit in.

In retrospect it was stupid, and too risky. But it was fun.
