Once we hit the road, things were as you would expect. The minivan was on the highway! Sammy my 4 year old was seated behind me watching cartoons on his tablet, and Alice my 9 year old was in the back of the van on the bench seat, texting friends and listening to her IPad. My wife and I were focused on the road and our long trip ahead. We never like to stop for anything other than food and gas. We always continue straight through the night. Throughout the years we have got this driving thing down to science. In case you didn't remember both my children are diapered up, to prevent any accidents, like I said no stopping!

After about 2 hours of driving Sammy started complaining about his wet diaper. My wife as the passenger was on diaper duty, so she happily unbuckled herself and crawled into the back of the van. She positioned herself in front of Sammy and pulled off his pants. She then undid his diaper exposing his tiny hairless cock. Elizabeth (My wife) instantly took his cock in her mouth, she worked him up and down with her tongue, licking his little shaft all over. She took his entire cock and balls in her mouth at once! I was trying to keep focus on the road and not get into a wreck, but I could not help glancing over at the erotic scene taking place over my shoulder. Know Sammy being only 4 was to young to cum, but he still enjoyed having his little dick sucked on, he sat there perfectly still as his mother gave him a top notch blowjob!

Just when I thought it couldn't get any better she licked her finger and slowly started to work her finger into his tight little ass. This started to get me really excited.... you see, we started working Sammy's ass a few months back. We are slowly working bigger objects (fingers, vibrators, etc..) into his ass in anticipation of me fucking him real soon! This lasted about another five minutes or so. My wife worked her entire index finger into my sons' ass while continually jerking and sucking him off. Finally, she grew tired of her sexcapades and finished up by putting a fresh diaper on Sammy pulling his pants back up and making him lick her finger clean!

Now, once my wife was back in the front seat she looked at me and said "my pussy is so fucking wet I need to get off" she popped open the glove box and took out an eight inch dildo/vibrator. She lifted up her dress and put one leg on the dash exposing her neatly trimmed bush and went to town. It wasn't long before she was cumming all over herself, She must have had two or three orgasms before she put the darn thing away!

Surprisingly we had not heard from Alice this entire time. I think the little bitch was trying to show me up because she really resented being in that diaper! After about 3 hours of being in the car the gas was on 'E' and a quick refill was in order. We pulled off the highway and into the first gas station we saw. I gave attendant my card and had him fill it up. My wife and I ran inside to quickly use the restrooms and grab some light snacks. When I came back out the refuel was complete and Alice started complaining that she need 'to go'. Tough shit kid, I replied. You should of said something before we went in. My wife jumped into the drivers seat, me into the passengers seat and off we went! Alice continued to pout in the back but went back to her music after a short while.

After an hour or so Alice really started whining about pulling over, she was on the brink I knew it. Tough cookies, we have a schedule to keep I shouted. After a few minutes she got real quiet. I knew she had done the deed. I waited to see if she would say anything but she sat there in silence. After about a half hour I asked, 'Hey Alice, you still want us to stop' she quickly said 'that's so not fair you know its too late for that'!

'Well looks like I better come back and change you' I replied. I quickly undid my seat belt and jumped into the back seat. I gave my daughter a peck on the forehead and whispered into her ear "I knew you wouldn't last". She turn and looked at me with a little look of disappointment, I gently placed my hand on the back of her head pulled her close and started making out with her. I passionately worked my tongue in and out of her mouth as I felt my cock slowly stand up in my pants.

I broke the kiss only to unfasten her seat belt. I reached my hand under her sweats and started rubbing her pussy through her heavy wet diaper. I was fully erect now....there was no stopping me. I quickly removed her sweats and whisked off her tank top too. I began to suck on her flat chest as I undid the straps on her diaper. She lifted her butt off the seat and I removed the piss soaked diaper from her bottom. I slowly worked my way down from her chest to the top of her bald mound. I quickly engulfed my mouth over her slit. Licking her up and down slowly, rubbing circles on her clit with my index finger. She tasted so childlike, clean with hint of fresh urine, I was in pedo heaven.

Now, Alice has been able to cum for over a year now, so even though she was pouting at first she knew she would get what she wanted. After about 5 minutes of licking her tight slit up and down and fingering her beautiful pussy she started to breathe heavy and thrust up and down really hard on my face! Orgasm achieved....My turn! I sat up on my knees and took out my erect cock. I grabbed Alice by the hips and pulled her butt to the edge of the seat. I lined the head of my cock with her bald cunt and started to work my way in. I would push in a little wait a few seconds then slowly work deeper and deeper, she was so tight it was amazing, I sometimes get hard just at thought of her pussy.

Now, I have been fucking her for several years now, but she can still only take about three and half inches of my cock. I slowly started working it in and out of her while I alternated between kissing her and sucking on her flat chest! 2 minutes later I couldn't take it anymore, I needed release. I took the head of my cock and jammed it in her pussy as deep as it would go. I then began to jerk off the shaft of my cock into her bald pussy. A minute later I felt the pressure building and several loads of cum began to fill my daughters pussy! After I came down from my intense orgasm I looked down at my daughters cum soaked snatch and gave her a flick on the clit as my cum slowly drained out of her.

I picked up her ass and placed a new diaper under her bottom and sealed it shut, The thought of her cum filled pussy and diaper was almost enough to get me hard again. I sat down next to her so she could lick my cock clean. When she was done we both got dressed, I gave her a peck on the cheek and returned to my seat up front.
