Hey babe... it s time for a diaper check during our road trip. It s wet already & still have many miles to go but.. uh oh... what s that look on your face? Do you need to go #2? There s no rest stops for a long time... you re wearing your bathroom so you may as well use it. I promise, I ll change you afterwards. Let s pull over and I encourage you to push it all out as I look you in the eyes & get so turned on by watching you. I can feel the load in your diaper. Lean back babe, I m just going to untape the top tapes, pull your rock hard dick out & pointed up and straddle you cuz I need to pee too. You feel it trickle all the way down into your already full diaper. Since I m practically grinding against your rock hard member I may as well just... slide down on it. We have messy diaper sex and both cum. Now it s time to lie back while I casually change your messy, soaked diaper in the backseat.
