Daddy and I (M/f) are going to be going on a roadtrip in a couple of days and we're looking for some ideas on what we could do to spice up our 20 hour journey!

The plan is for me to be easily accessible, meaning no bra/panties the whole trip, but possibly with a crotch rope harness. We're also going to be taking along a vibrator and possibly some other toys.

He's got some sadistic tendencies and I have some masochistic tendencies (though I think I lean more toward emotional masochism than physical) In general we're into orgasm denial, objectification, a bit of humiliation(but nothing major).

I just want to be an entertaining toy for him to amuse himself with as we drive, but I'm coming a bit short on tangible ideas.

Which is what brings me here. What do you do on roadtrips? Or what would you like to do/ have done to you?
