I'll sit on her lap

“I’ll sit on yours I guess.” You tell Robin.

“Somehow I thought you’d say that.” She replies with a smile.

Jenny gets in the car and turns on the motor while Robin sits down in the passenger seat and leaves the door open.

“Well, hurry up!” Robin says playfully.

You feel a little silly preparing to sit on a girls lap but for some reason you feel like this is the right choice. You maneuver yourself awkwardly into the passenger side of the car and as you begin to sit down Robin places her hands on your hips and helps guide you to her lap.

Click… Slide… Swish… Plop!

As you were sitting down Robin abruptly unbuttoned your pants and slide them and your underwear down passed your butt cheeks. This strange act makes you want to hesitate but you can’t as Robin simply pulls you down onto her. At the same time you feel something long and hard pushing itself into your ass. After a moment of confusion you realize that Robin has you riding her cock while the car speeds off towards your destination. Good thing for you your ass is well lubed from your all your previous fun in the men’s room.
