"Alright sweetheart, you're in timeout - from now on, I don't want to hear a single sound from you."
"Wha- " it wasn't fair. But before I could protest, Beth pressed her index finger above my mouth and gave me a stern look.
"You promised to be on your best behavior, remember?" With a swift motion she tapped my cheek and grabbed the pacifier gag out of my diaper bag. "Open wiiide!"
I complied. What choice did I have? I was strapped into my booster seat, wearing nothing but colorful wool tights, a onesie and my locking mittens. Oh, and of course the extra thick nighttime diaper that I was put in before we started our drive. Which I thought was the reason that we exited that endless stretch of a highway. Of course, I'd never admit that the stench was coming from me, but as I had not yet been able to come up with a scapegoat to blame it on, I assumed that Beth and Pops knew that I was in dire need of a change. So to get to the point, the noise cancelling headphones that Beth now pulled out of the door pocket were kind of confusing considering that she still had not unbuckled me from my containment. Especially since there wasn't really a reason not to change me - I had not begged for a change, I had not gotten on anyones nerves by asking "are we there yet" every other minute and I (albeit for the lack of ability with those stupid mittens) had not thrown with little pretzels to get some attention.
"mmmghh" I protested. But Beth had already placed the headphones on my ears and gave me an indistinct smirk. What was she up to?
The car shook when she slammed the door shut. Pops had gotten out of the drivers seat and walked out of my field of view as well. What were they trying to do? We were in a little parking lot in the middle of the night, in the middle of nowwhere. No gas station to buy snacks or bad coffee from, not even a lit path to take a quick stroll to wake up, it was literally just a pitch black empty parking lot.
The headphones began to play music.
Itsy bitsy spider, went down the water sprout.
Come on. I was so happy that I was allowed to listen to the radio with them instead of this crap.
Suddenly, I felt a cold breeze coming from behind me. The trunk? Maybe I'd get a change after all. Although I'd have to admit that the diaper bag that was still sitting next to me was not really a strong indication that my caregivers were going to prepare my change in the trunk.
As a small jump went through pops SUV, it dawned upon me. Oh oh. With another slight breeze, the boot lid was shut again. Those stupid big sidewalls of the booster seat and the tight straps that were still securing me very effectively kept me from taking a peek and seeing what was going on back there. But I didn't need to. Those small little stomps that went through the car were enough to tell that Pops and Beth were both climbing around in that spacious trunk. Not too long ago, I'd have been in Beths place actually. You may not believe it, but I wasn't always a diapersoiling little brat. But things had changed 'round here.
As the worn out shocks from the car started to replicate the rhythmic movements in the trunk, the little lady in the headphones started to sing the next song.
The wheels on the bus go 'round and 'round, 'round and 'round, 'round and 'round...
Damn, that was a new low. My crotch started to get tingly as I thought about the times when I'd be the one to get railed in some abandoned parking lot. How I'd bend over and get into very demeaning postures. I had always had a thing for humiliating myself. Of course, the humiliation of getting fucked in the back of a car and continuing the drive while Pops sperm was oozing out of me and into my panties was quite a bit less humiliating than being strapped into a booster seat in a completely wrecked diaper while the vibrations from my daddys new girlfriend were teasing me through the swollen padding pressing against my crotch.
I let out a sharp sigh as the next song came on. How do they always crank it up a notch? The worst thing was, I couldn't even say that I wasn't enjoying it. Of course, while sitting an arms length away from the two love bunnies, I didn't dare to grind the mushy mess between my legs against that crotch belt, but I knew that this would be food for quite a few rustly nights while Beth and Pops were asleep.
By now, they had found their rhythm. The way the car replicated it was almost comical. Yet, with the peefilled diaper and the - ehem - contents in the back, I was getting worked up even more. Not enough to cum of course, but definitely enough so that if I didn't get a change before we continued the drive, I wouldn't be able to ever calm down with the roads vibrations. I suckled more on the pacifier to calm me down a bit. Getting all riled up wasn't going to do anything besides frustrating me.
It felt like ages until they were done, although it probably only took four or five of these highpitched annoying songs.
Finally, Pops face appeared on the window next to me. After he took off my headphones, he unbuckled me and helped me out of my car seat.
Before I was lifted into the boot, I saw the remains of their little session. Beths bra was still dangling from the headrest and next to the big changing mat that was spread out over the whole trunk, a very full condom proved that I wasn't the only one who urgently needed this little stop. Beth, who had been eyeing daddy and me while he carried me to the trunk, gave me a wink and took another big drag from her cigarette.
With an audible quelch, daddy laid me onto the changing mat and started to get to work.
"Oh, looks like someone still remembers our little adventures in the trunk, huh?" Of course he couldn't let my throbbing vulva uncommented. With my pacifier gag still in, I could only nod and hum in agreement, causing Beth to laugh bright as a bell about my obvious desperation. She handed Pops the wipes: "Come on, let's get us going. You're the one who gave her all of that fruit juice, don't expect me to help with this mess."
After a very thorough clean up, Pops placed the new nappy beneath me. Beth, who had finished her cigarette in the mean time, handed him two stuffers. "Let's just pimp this diaper a bit so we can send her straight to bed when we get home."
To my despair, Pops nodded. Of course, practicality was always a big plus for him.
"Hold on!" Beth intervened another time. "We totally forgot to get that poor thing a bit of pleasure as well - make way" she ordered. With big eyes, I followed her movements.
She grabbed the used condom, untied it and poured its plenty contents all over my princess parts. She really knew how to crown the scene.
By the time she pulled my tights over my now not so freshly diapered bum, Pops had already returned from the trash can and got into the drivers seat. While Beth pulled the seat belt extra tight to spread that sticky goo around in my crotch, daddy started the engine of the suv.
High time to get me to bed.
