We had left the changing room and courts behind us as I drove along the highway. North and out of town. For what Molly and I both wanted to happen we needed to be sure that no one would possibly see us. As we drove we each had one hand on each other's lap, mine occasionally massaging her diaper to make a satisfying crinkling noise, and hers every now and then pumping and squeezing to maintain a consistently semi cock in my pants.
I had opted, when we were getting dressed again back in the changing rooms, to forgo my underwear. Normally a dangerous move, but today I wanted as few layers as possible separating Molly from my cock.
Under my fingers I felt the texture change as Molly sighed a little. While one hand clenched the wheel pointing us further and further down the road, the other was feeling her release herself into the absorbent diaper that hugged her leaking pussy. Darting my eyes between the road, her diaper and her face, I saw a sign indicating a turn out 1 km ahead.
Molly's sighs became increasingly breathy under the weight of an approaching orgasm. Carefully managing both the damp diaper covering Molly's inflamed clit and the steering wheel, I pulled hastily off the freeway and put the car in park.
"Put your chair back and lay down princess," I directed. "Daddy needs to slide into your diaper."
Molly was happily obedient. She pulled the lever and pushed the chair back. "Like this, daddy?"
"Yes, just like that." I replied.
Momentarily my hand was inside her warm, wet diaper, my middle finger deep inside her slippery, wet pussy. She moaned and I worked my finger in and out of her hole. It was awkward in the front seat of the car, but when I looked around I noticed that we were alone in the turn off.
Molly had her track pants around her ankles, and was sitting in her t-shirt and a diaper. I pulled my hand out from her diaper, and said, "baby I want you to lay down in the back of the car so that daddy can see what you've done to your diaper."
She unhooked her feet from her track pants, leaving her wearing only her shirt, diaper and shoes. I opened the door as she did too, we both walked to the back of the car, and when I drew open the tailgate she instantly sat and gazed into my eyes cheekily, beggingly and said, "daddy, I think I need a minute, and then you'll need to really change me."
Her expression changed to one of concentration and bliss. She bit her lower lip again as I watched her squirming slightly. I knew what was happening as her diaper crinkled underneath her, and I imagined her mess spreading under her weight as she sat directly on the floor of the car's trunk.
After a moment, she moaned and said, "oh my god daddy, that feels so nice in my diaper. I know I'm not supposed to, but I like being your little girl."
