M4F - Car Ride (Family?)

My Dad and your Mom have been dating for a while and they are taking you and I with them on a camping trip. With all the supplies stuffed into the car, there isn't much room leftover for sitting. Our parents took the front seats so that leaves only one seat left for the two of us. The boxes and bags of food are taking up nearly the entire back seat, not even the middle seat is open, just one passenger seat. It looks like there is only one option, you'll have to sit on my lap, for the entire car ride to the camp site.

Please tell me what you are into for this scene and if you have any specifics in mind for your character or otherwise. I'd love to play this out for much longer than the car ride if things go well, the camping, the ride home, even after that.

Bonus if you include a picture of your character. I'm also open to changing the dynamic a bit, step/siblings or something along those lines. Feel free to check out any of my old prompts too.
