A demeaning car ride.

"Yes, baby girl, Emily," Julie told the stunned Kylee. "Someone has to take you home with Michael gone, and Emily very kindly volunteered, despite her busy schedule. Wasn't that nice of her?" Kylee's new nanny said with a sternness that implied there was only one right answer.

Sitting on her diapered ass in a giant highchair, clutching a bottle with a mysterious milky liquid that Julie would only call 'Nanny's special milk,' Kylee knew she was in no position to question anything Nanny told her to do. "Yes, that's very nice of her," Kylee said with the flat, performative tone of a teenager being **** to say something polite by their parents.

"Great! I knew it wouldn't be a problem! Plus, you don't have to worry your pretty little head about having to hide anything from Emily. I've filled her in on EVERYTHING regarding your situation," Julie said cheerily.

That statement stunned Kylee. Emily, the most beautiful person, let alone woman, Kylee had ever seen, her gym crush, KNEW she was being reduced to acting like a horny little toddler. Kylee didn't think she could feel more humiliated than she had when humping a stuffed bear in a poopy diaper earlier in the day, but the wave of shame that hit her on learning Emily knew about it threatened to overwhelm it. Kylee dropped her bottle.

"Emily... Emily knows... EVERYTHING?" Kylee stuttered out. Her half full baby bottle started to roll on her tray towards the floor. Julie adroitly caught it and handed it back to her charge.

"Yes, baby, everything. She particularly enjoyed watching the show you put on for me with Mr. Bear," Julie responded nonchalantly. "Oh, don't act so surprised! You know she already knew that you had to wear protection to the gym after your last visit. She was the one to check if you were wearing a pullup today. Also, taking care of you is going to be a difficult job. I am going to need some help. Emily has also agreed to provide that help." Julie continued. "Isn't that so sweet of her?"

"She's going to HELP you?" Kylee sputtered, outraged at this new information.

"Really, she is going to help YOU sweetie. YOU are the naughty little girl who can't control her pee-pees and poo-poos. You are the naughty little girl who gets off at wearing poopy diapers and letting another woman wipe her ass and puss-puss. You should be ecstatic that a woman as wonderful as Emily would even consider offering to help me with someone as pathetic as you," Julie lectured Kylee. "Now, I won't hear another peep out of you about this. Finish your bottle and know that I expect you to obey Emily as well as, if not better than, you obey me. If I hear a single breath from Emily that you weren't a perfectly behaved little toddler for her, what you went through today will seem like child's play compared to what it will take to convince me not to share the videos I have of you with Michael."

With the stern warning, Kylee pressed the nipple of her bottle back up to her mouth and started suckling down the sweet milk again, all the whole glowering at Julie.

"Good choice baby. Now, finish that bottle. Emily will be down here to sign you out if daycare soon." Julie said.

Kylee finished her bottle without further incident while Julie went about mundane tasks of cleaning the daycare. After Kylee finished her bottle, Julie left Kylee sitting in the highchair with nothing to do but sit alone with her thoughts. Kylee didn't have to sit long, however, because just a few minutes after she finished her bottle, the door to the daycare opened and Emily walked through with broad, mischievous smile on her face.

"Julie, I'm here! Is our little stinker ready to head home?" Emily said sweetly, ignoring Kylee's face turning red at her words.

"Oh yes. Little Kylee napped like a champ after her playtime. I got her changed out of her poopy diaper, and she's had a bottle of my special milk. She's all ready for you to take her home," Julie said, clinically recapping Kyle's morning to Emily like she would to the parent of an actual baby left in her care.

"Wonderful! Is there anything she needs to take home with her?" Emily asked, still ignoring Kylee like she would any toddler.

"Yes! Here!" Julie approached Emily carrying what Kylee could very clearly tell was a diaper bag, "I put together this special 'gym' bag for Kylee. It has enough changing supplies, diapies and pull-ups to get her through to tomorrow. She'll need to bring it when she comes everyday to get a restock though."

Kylee groaned internally. Of course she would have to start carry around a diaper bag. Julie had proven her nothing if not adept at torturing Kylee with her thorough attention to detail.

"Wonderful, I am sure little Kylee will remember to bring this back," Emily said, throwing the pastel pink diaper bag over her shoulder. "Well, then, I guess I have everything I need. It's time to go home, Kylee!" Emily said with a saccharine sweet tone as she walked over and helped Kylee out of the giant highchair.

Kylee looked down at her feet as Emily placed her hands in Kylee's armpits and lifted her out of the chair. Kylee couldn't bring herself to make eye contact with Emily. Being treated like nothing more than a toddler by Emily, plus the physical contact with her was causing Kylee to flash back to her most recent dream where Emily was a main character. Kylee's humiliation, plus just being in close physical proximity to Emily, was causing Kylee's pussy to throb with arousal again.

Emily, seemingly unaware of the aroused state of the pathetic woman standing next to her, gave Kylee an appraising stare. "Oh, Kylee! You look SOOOOO cute in your little pampers!" Emily squealed in delight. Her words sent a fresh wave of arousal through Kylee's body.

"Now, sweetie, why don't you go give your Many a nice big hug and tell her thank you for taking such good care of you today, even though you were pretty naughty, and Ms. Emily will give you a drive home," Emily ordered Kylee like she would a toddler. "Oh, and Kylee, make sure we both believe you mean it," Emily followed-up with a much more menacing tone.

Kylee, based on her previous conversation with Julie, new she couldn't disobey Emily. So, with all of the exuberance she could muster, Kylee waddled over to Julie, her Nanny, and embraced her in a clumsy but big hug. Julie's height **** Kylee to bury her face in her Nanny's breasts as she hugged the woman, which confused Kylee for a second. For some reason, Julie's breasts smelled a little bit like the milk she had just drank tasted. Shaking off the thought, Kylee focused on finishing the task assigned to her by Emily.

"Tank you Nanny for the fun day!" Kylee lisped out in her best impression of a toddler saying good bye to her favorite babysitter. "I'm sorry I was a bad girl today! I pwomise to be better tomorrow."

"Oh, sweetheart, it was my pleasure. I am sure you will get your behavior turned around tomorrow. Don't forget to send me those pictures you promised!" Julie said, wrapping her arms around Kylee and pulling her even more deeply into the embrace.

Kylee shuddered slightly at the reminder that she was now expected to be a bedwetter. However, the concern passed quickly as she let herself be pulled into Julie's body. Kylee had to admit to herself, being held like this felt oddly comforting and, dare she even think it, right?

Emily walked up behind Kylee, rubbing the diapered woman's back as a subtle signal it was time to let the hug go.

"Alright sweetie, I am glad you love Nanny so much, but we really have to get going. Grab my hand, and I'll show you to my car," Emily directed Kylee.

Kylee let go of Julie, unburying herself from the large woman's gigantic, sweet-smelling breasts, and let Emily lead her out of the daycare by her hand.

As Kylee waddled out of the room hand-in-hand with the woman she had just had a graphic sex dream about, Julie called out to her, "Bye-bye Kylee! Be a good girl! I can't wait to see you tomorrow!"

Kylee turned red, but continued to let Emily lead her like a small child out of the daycare and through the gym. During the walk, Kylee kept her head down. She was aware that her childish diaper, labeling her a "Potty Pants," was on display to everyone else in the gym. She could feel the eyes of everyone on her. But, Kylee also knew that all she could do was keep her head down, swallow her embarrassment, and hope that maybe, the other members of the gym would forget this incident quickly.

Emily and Kylee made it to Emily's vehicle relatively quickly. Kylee looked up as Emily slide open the back door to, what Kylee was surprised to discovered, was Emily's minivan. Kylee looked into the pristine vehicle and noticed four open seats in the back. She did see one had a very large, rear facing car seat strapped in place. Upon seeing that, Kylee immediately became concerned.

"Um, Emily, do I have to sit in the back? I'm big enough to sit in the front with you," Kylee said, hesitantly.

"Oh, Kylee, we both know you aren't BIG enough to sit in a normal car seat, let alone up front. I saw what you did to your last diaper while you were sleeping. There is no way I am letting you sit directly on my upholstery and ruin it," Emily said, causing Kylee to turn red yet again. "But, I am sure you are plenty small enough to fit in this car seat. Nanny helped me install it special for you! Wasn't that nice of her."

"But..." Kylee tried to protest. However, before she could get another word out, Emily had produced a pacifier from the pocket of Kyle's new 'gym' bag and popped it in Kylee's mouth. Kylee accepted the pacifier and began suckling it indignantly, remembering Nanny's rules regarding pacifiers.

"No 'buts,' stinker! Climb up into your car seat now, or there WILL be consequences," Emily said, smacking Kylee on the diaper for emphasis.

Kylee furrowed her brow, but complied, climbing into the giant, rear facing car seat. As Kylee settled into the seat, she was amazed to find that she fit in the seat, if just barely. Regardless, the seat wasn't comfortable. Because of how it was positioned, Kyler was **** to spread her bend her legs sharply and spread her knees wide to have enough legroom to sit comfortably. Beyond being a little uncomfortable, it **** Kylee to expose the front of her giant diaper. Kylee didn't need to be worried about her diaper being exposed for long though.

Once Kylee was settled in the seat, Emily leaned into the van, placing the pink diaper bag next to Kylee's seat, and leaned over Kylee. Emily then quickly thrust her hand between Kyle's legs, under Kylee's diaper, and pulled out the car seats crotch strap.

The sudden, unexpected pressure in her groin, being caused by Emily, of all people, sent an immediate waive of pleasure through Kyle's body. Involuntarily, Kylee's eyes rolled back in her head and she let out a low moan from behind her pacifier. Emily, her face incredibly close to Kylee's because of her position over Kyle's carseat, looked at the other woman and raised an eyebrow.

"Oh, you ARE a dirty little baby, aren't you? Your Nanny warned me you were sensitive, but this is impressive," Emily said as she placed her palm on Kylee's diaper and rubbed it a few times, teasing Kylee. "I'll have to remember this," Emily continued as Kylee moaned again.

Emily stopped teasing Kylee and quickly finished buckling Kylee in. She made sure to synch the straps tight, ensuring the crotch strap pressed firmly into Kylee's padded pussy.

"Looks good!" Emily said as she stepped back admiring her work. As she looked on, she noticed that Kylee had started lightly grinding on the crotch strap. That gave her an idea. She popped the pacifier out of Kylee's mouth.

Holding the pacifier in her hand, Emily asked Kylee, "Now, baby, do you want your paci for the car ride or do you want to be able to talk?"

"Um, talk," Kylee said.

"Good, I'll allow it, but you need to promise to be a good girl and do exactly as I say. Can you do that?" Emily continued.

Sensing a trap, but wanting to avoid the added humiliation of sucking a pacifier while wearing a diaper and being strapped into a car seat, Kylee responded, "Yes."

"Good girl," Emily said as she closed the sliding door to her van and climbed into the driver's seat. Emily then turned on her van and adjusted her mirrors. Due to a well positioned mirror on the headrest of the seat Kylee's car seat occupied, Emily could clearly see the diapered woman's diapered crotched rubbing against the strap of her car seat.

Emily turned on her radio and switched the station quickly. Kylee groaned as Emily settled in a station that seemed to only be playing children's nursery rhymes.

"Perfect," Emily said to herself as she pulled out of her parking spot and began driving Kylee home.

Emily had previously gotten Kylee's address from Michael, so she knew where the other woman lived. She also knew there were two ways to get to Kylee's house. One, the more direct way, involved taking a smooth, paved road with little difficulties. The other way involved taking gravel roads, roads under construction, and roads that crossed train tracks for a much more bumpy ride. Given the humping motion she was still seeing from Kylee in the back, she knew the other woman, and Emily herself, would get a lot more enjoy from the bumpier ride. So, she proceeded to take that path.

Emily was right. As she drove down the various bumpy, unpaved roads, with nursery rhymes blaring in the car, Emily could see Kyle's diapered crotch rubbing more and more furiously against the strap of her car seat. Emily could hear Kylee's breathing accelerating punctuated only by soft moans. About halfway through the drive, Emily decided to amp up the humiliation and pressure. The Wheels on the Bus started playing on the radio at about the same time the van hit a large bump, causing Kylee to admit a particularly loud moan. Emily could tell Kylee was close.

"Baby! This is one of your favorite songs! Why don't you show Ms. Emily what a good little singer you are and sing along!" Emily yelled back to Kylee.

Singing along to a baby song was the last thing Kylee wanted to do right now. Being treated like a toddler by Emily, just like in her dream already had Kylee in a heightened state of arousal. Each bump of the van, forcing her diapered crotch against the car seat strap, was providing her more than enough stimulation to cum. It was taking all of her concentration to not orgasm while sitting in the car with Emily. However, when Emily ordered her to sing along, so knew she had to comply. So, as the song continued, she knew she had **** but to sing.

"The WHEELS on the bus go round A... AND round," Kylee belted out with all of the enthusiasm of a toddler, unintentionally emphasizing words wear bumps caused her pussy to rub against her diaper. "Round and ROUND, round and ROUND," she continued as Emily giggled at Kylee's moans.

As the song continues the road got bumpier, and Kylee started to lose her battle to keep her dignity. She was finally pushed over the edge just a half mile from her home when Emily drove over a street that was crossed by four different train lines. The vibration of the tracks combined with her humiliation, the arousal of being around Emily, and the divided focus of having to sing pushed her over the edge.

"The BABIES on the BUS go.... ahhhh, Ahhhhhhh, AHHHHHHHHH!" Kylee screamed as she came in her diaper for the second time that day.

"Great enthusiasm baby! Such a beautiful singer!" Emily said smugly as she felt her own pussy throb in pleasure from watching the diapered woman in her backseat debase herself so thoroughly. "Very good girl," she said, moaning slightly, as she let her right hand drift to her clit and rubbed herself slightly, enjoying Kylee's slowing fading gasps of pleasure.
