Dr. Sloan was driving us across the country to visit my polycule. She was the closest thing I had to a Caregiver. In this day and age, a Kinky Lifestyle Little like me couldn’t be picky. The State had a huge nation-wide curfew on travelling this time of year. Dr. Sloan had connections. Dr. Sloan, who told me, many times, to call her by her first name, Lakshmi, had to make one simple phone call and all was taken care of. 

So there we were, I was sitting shotgun in her Chevrolet Suburban. The road from Iowa to California was bumpy and full of barbed wire and wasteland. It was December in Post-World War Three, America, but it might as well have been World War One, Siberia with how cold it was. 

“You’re squirming. Do I need to turn up the heat?”

Her voice ripped me out of my reverie and I adjusted my glasses as I turned to look at her. 

“No, I just gotta potty, I can hold it though.” 

“You should have gone when we stopped at the fuel lodge several clicks back.”

“I didn’t have to go then.”

‘Clicks’ I loved when she used that kind of military slang. Dr. Sloan was a veteran. She fought in the war that raged across the planet and turned most proud countries into unified wastelands of solidarity through survival. It made going to a meeting like this more important.  I had been talking to Harriet for fourteen years and Bellanie for seventeen years and we’d never met offline before. This would be the very first time.  This year, we were going to be each others' Christmas gift. 

“Lucky for you, I came prepared.”

I was ripped away from my thoughts again, “Ma’am?” I asked, as she pulled over the car to the side of the road, and turned off the ignition. 

“I’m not waiting for you to get desperate and have to squat on the side of the road - not when  I have a warmer option than risking you getting frostbite on that pretty little cunt of yours.”

“Wha--?”

I watched as Dr. Sloan took off her seatbelt and pushed the seat back. She started hiking up her skirt. I could see the tops of her thigh highs, her petticoats, and garters.  It made me flush with emotion and I wanted to look away but I didn't. I liked what I saw, especially once she spread her legs a bit. 

I heard a crinkle sound as she started unfastening the sides of an adult diaper. She spread her legs further apart. They opened enough that I could see her girlcock peeking out of its nest of soft, fluffy, dark hair. 

“You’re gonna go potty in my diaper. C’mon hurry up now, there’s another patrol due down this road soon. We don’t want to get caught doing this. Straddle me and go potty in my diaper, it’s okay.”

“You’ve been wearing a diaper this whole time?”

“I told you,  I came prepared.”

My bladder chose that moment to pulse its need to be emptied and I bit my lip but  wiggled my panties down under my own skirt and reached to set them on the dashboard. 

“Ah, ah, ah,  hand those here.  Your panties, Mya, give them to me, you silly girl.”

Fisting the pink fabric into her bigger palm, I moved carefully to straddle her. Her other hand held my hip, as I pushed up my shirt and  made sure I was angled to aim on the diaper and not make her leak.  She ran her hand over my arm,  “It’s okay, just let go, it's okay…”

I leaned forward, feeling the top of her girlcock kiss my pussy, as I lowered my squat. I felt tingly and excited doing this.  I wrapped my arms around her neck, pressing my face into her warm neck, and let myself let go. The hissing of my piss started slowly, trickling out, and I felt Dr. Sloan suck in a breath,  “That’s it, good girl, let it all out…”

It felt so intimate and illicit to pee like this. The slow trickle was a more steady stream now. The heat from my piss was fogging the windows. I glanced up, just in time to see her nostrils flare, enjoying my scent. I felt the warm tinkle against my clit and whimpered my aroused noise and Dr. Sloan chuckled.  “Are you getting excited, little one?”

“It just feels good to pee.”

“Yeah?  Or does it just feel good to pee in my diaper?”

“Mmhmm...”

“Good girl.  All done?"

“You’re gonna keep it on? You’ll be all wet!” 

“Mm, I’ll be nice and warm.”

I hid my face in her shoulder feeling bashful. She chuckled as she swished some of my long braids aside and placed a kiss on my neck.

“Mmmph, If you keep doing that, I’m gonna wanna ride your girlcock til I see sparkles, Doctor.”

“Maybe that’s the idea. Ever think of that?”

I pulled back enough to look at the smug expression on her face. I gave her one of my own, in return. Boldly I slid my hand up her shirt to curl my fist around the handful of tit. Kneading her nipple into my palm, I watched the way she squirmed under me. 

“Tease,”  she chided, and reached down to angle her now hard girlcock into my pussy. 

“We gotta make it quick, we don’t want to be late to - Ah!”

I sank down onto her, the diaper crinkling its enjoyment between us.  I rode her hard, making the car creak its joy as well. 

“Easier to see the arrival of comets at night anyway. It will be like the story, only instead of three wise men it's two horny lesbians. We got time… we got time...” I assured her, panting with effort from my movements. 

“So tight and warm…”

“Uh uh… not yet.  Let me get my sparkles first, please?? I’m almost there… I’m almost there.” 

I squeezed her tit again, they were so small and reactive, my favorite. Mine were big and heavy and got in the way all the time. But the way she watched them jiggle and bounce, right then, was worth it.  I watched her eyes lose focus, and her brow furrowed with concentration, trying to hold back.  Watching her fight her body was turning my body on more and more.  “Keep holding it. You can do it, can’t you, Lakshmi? You can hold on a little while longer, huh? Yeah. Yeah you can…”

I tipped my head back, creaming my cunt around her girlcock, cumming hard and strong. Bucking back, that I hit the horn on the car and it startled us both, that we laughed. Lakshmi gripped my hips, letting go of her load inside me, quiet and hot, like a secret.  I felt her face press into my chest. Her breath heavy, body shaking the last drops out while she was still cumming hard.  After a moment, Lakshmi lifted her head, wiped her face of sweat.

“Now close my diaper. We need to get back on the road.”

“Yes, Doctor!” I said and lifted up enough to push the diaper back up and refasten the strips on the side. I got back over to my seat.  “Panties please?” I asked, sweetly, holding my hand out for them.  

We both got re-situated and re-adjusted. She started the car again and got us back on the road.  Passing the patrol car on our way,  who saw the travel pass sticker on the windshield so we didn’t have to get stopped and searched. Lakshmi laughed.  “And to think I was contemplating asking you for a little road head. That was much better.”

“Ho ho, ho!” I laughed, “We bring crinkly, warm, wet tidings of great joy and arousal. Lift the skirts and unwrap to enjoy.” I continued my joke, expecting to hear her signature chuckle of being lightly amused. But Lakshmi's face was slack as her hands gripped the wheel. And I could hear a faint sound of hissing.

"Keeping warm, Doctor?” I asked with a wide smile.

"It is healthy to pee after sex. I will never break the habit."

"How much does that diaper hold?"

"We're gonna find out..."

I could hear her still going, the mingled scents of our combined piss, and sex, was heady as it baked in the recycled heat of the car. I slipped my hand in my panties, looking at the relief relaxing Lakshmi’s face.

“Tease.”  I whimpered as I fingered my clit, knowing full well that I was teasing her back with the action.
