It was a few years ago, I was going to the South of France with my girlfriend and her parents, her father was driving, her mother was on the passenger side and we were behind.

The road is a bit long, so we look for each other a bit, she stretches out her legs on me, pretends she's cold and hides under a plaid. In reality she pulls down her pants and I start to stroke her clit a little, then I get down between her buttocks and start fingering her ass. 1 finger then 2 then 3, she strokes herself at the same time still under her plaid with her parents right in front until she comes, holding back of course not to scream then gets dressed very gently.

Then she comes and lies on top of me, her head level with my cock, and still hiding it with the plaid, pulls it out of my pants and starts licking my head a bit, I'll let you imagine my state between excitement and fear of being captured by the father-in-law.

Finally we stop for a bathroom break, the parents get out of the car and my girlfriend starts sucking me harder. And just as I was about to cum, I saw her mother coming in the rear view mirror. It turned me on so much that I let it all out in her mouth, and a little on myself as she quickly straightened up to avoid getting burned while swallowing my cum. It smelled like sex to death in the car so I got out to clean up a bit. But I'm sure the parents understood that we'd done some dirty things.
