This story started through some role play with a friend on SK. I then continued the story during some downtime at work. You're picking this up after Ashley is discovered to have a few secrets by her friend Lauren. Now Lauren is enjoying her friends discomfort - as is Ashley though she won't admit it, yet. 
The story has a few more pages, but it gets a little "rule 34" after the end and alluded to throughout. Friend me and we can discuss getting the rest.

You made it through most of the game without being too embarrassed wearing the bright pink Hello Kitty plastic diaper cover. You actually forgot all about the glossy plastic pants as you cheered through the game. If anyone noticed your pink diaper cover compared to all the other girls blue bloomers no one brought it up. The crowd was much too loud for anyone to hear the crinkle of your diaper cover but you believed everyone could.

Every pause in the game you would look from Lauren to Apollo sure she would pull some trick to humiliate you in front of the crowds in the stadium. Apollo had evidently been turned into the team mascot. The team, being the Rockets, tying his name to the famous moon mission rockets, had put a team shirt over him. He sat watching the activity, getting petted by all the people on the sidelines and loved the notoriety. Lauren asserted that Apollo would now come to every game.

The Rockets won. You cheered your team victory. Even Apollo wagged his tail and appeared to smile. The players ran back to the locker rooms. The throngs of people made the walk back to their cars. Lost in the moment of the team victory you bend over and grab your cheer gear, blushing instantly, you quickly squat. You stuff your items back into the bag looking around suspiciously.

Relax, Ashie, no one is around to see, says Lauren as you stand to meet her approach.

You look around and surprised everyone has gone.

Wheres Sissy?

Oh, I dont know, Lauren waves dismissively, Off fucking the team, maybe.

Lauren pats you on the bottom. You feel soft pat-pat against your diaper. As much as you glare you blush equally.

Still dry, cant have that. Lauren smiles at you and she pauses before saying, Well?

You look quickly from side to side. You dont see so much as a bird fly by and rather than argue with Lauren and possibly make a scene you let your bladder empty filling the diaper substantially. You feel relieved having held it in most of the game. As you do this Lauren reaches her hand between your diaper and diaper cover.

What the F, Lauren! you dont stop her but get closer so youre not seen with her hand in your pants.

Mmmm, so warm, she gushes. Quite a flow you have going, and her smile widens and still going! My, oh my!

You pout as you lose control of your bladder and every golden drop is squeezed out into the now bulging diaper.

Oh no, You say as Lauren gently moves her hand back and forth and you feel the slosh of pee that did not get trapped in the absorbent material. Any slight movement you know will cause it all to leak. Lauren smiles aware of your predicament. You look Lauren in the eyes, smile and walk towards the locker rooms with big steps. The golden liquid spews from every gap it can escape from and trickles down your legs. 

Lauren glares at your back for ruining her fun with you and your wet diaper. She slowly walks to you with Apollo walking next to her. You smile trumping her at her game. Who is around to see if I peed in my diaper? Who is around to see my diaper leek all my pee? No one thats who. Ill just go to the locker room grab a diaper from the locker full of them be nice and dry. Hah, just to rub it in her face Ill put on two. You stop at the locker room entrance door, turn your head around to Lauren and stick out your tongue. You tug on the handle.

Nothing. 

You tug again.

Nothing. You pull harder. Maybe its stuck? As the door moves a bit you can hear the deadbolt rattle in the catch. Locked! Damn it. You scold inwardly. You turn to Lauren who is back to smiling.

Oh yeah, I forgot I told the janitor to lock up and not to wait for us earlier, answers Lauren to the question you were about to ask.

Lauren Im soaked. I need to clean up. My¦ you start to whisper, diapers are in the locker!

Oh Ashie, she says as she reaches into her bag and shows you a handful of diapers, Ive got you covered, literally.

You lunge to steal them from her hand but she dodges at the last second. More pee sloshes in and eventually out of the diaper. The approaching afternoon has chilled the diaper and you shiver.

Is your tinkle making Ashie all shivery whivery? coos Lauren.

Shutup, Lauren! The jumper skirt is soaked as well as your socks and sneakers. The slightest cool breeze sends a chill up your spine. Lauren waggles the diapers.

Im betting you were gonna put on two diapers just to spite me, chides Lauren?

N-no? you blush in reply and another chill sends goose bumps on your legs.

Three then! she smiles broadly!

Fuck no, Lauren! you yell and try to hide the shiver.

Lauren walks over to her car unlocks her door and gets in. You know it was an illusion, but you seriously believe you felt the heat radiate to you as she opened the door.

Damn remote starters, you say.

Lauren rolls down the window and the heat wave radiates in the cool air. Three!

Oh for fucks sake, fine you stomp over to her car. Lauren exits the car. You go to get in and she stops you.

Nuh-unh, youre not getting in all pee soaked. She starts to lower the zipper on your jumper.

Im n-not g-getting n-naked h-h-h-here, you say with definite teeth chatter.

Just strip, she sighs, You fight me on one thing and not the other. Make up your fucking mind

No, n-no, b-because y-you have one of m-my b-baby d-dresses in the b-bag, you wrap your arms around yourself, and y-your g-gonna m-make me w-wear it

No, this cold afternoon air is going to make you wear it, she twirls her finger to address the air.

You slump. A-alright, which one am Im wearing

She opens the back door and its what you feared. You see as your Mother calls it your formal dress dangling from a hanger. It is a short dress as all your baby dresses tend to be however this has more ruffles and lace a high collar. Out of all the dresses you are always most embarrassed when made to wear it. It is not the ruffles or all the lace or the abundance of said material on the matching panties. The dress is famous for when your Mother bought it, the exposed bottom.

The dress is designed so the panties with it lace, and ruffles and large bow make the back of the dress. Worn with three diapers, which youve been punished to do in the past, the backside is prominent.

Fuck! You draw it out as you notice she has brought the whole ensemble. The Bonnet, booties, mitts and the bib. All with equal lace and bows.

No, not all of it. You frown.

All of it! you see Lauren click the fob on the key and the doors lock.

As the words, No are about to pass your lips a breeze blows and chills every inch of you. Goosebumps break out on your pale skin. You argue internally with yourself. ˜Its dry, one side says. Yeah, but¦ says the other feebly. Youre so cold you cant come up with a convincing argument with yourself. Even your internal voice is now starting to chatter. J-just d-do it!

Un-unzip me! You turn quickly.

Lauren unzips the back of the jumper and with another quick glance around you slink out of it. Lauren unhooks your bra and your large breast swing free. Your nipples become erect in the cool breeze. You cover them but not before Lauren comes around and gives them a glance and smiles.

You reach for the dress but Lauren says, Nuh-unh. Holding up the diapers. These first. Because if you get the dress on youll fight me.

N-no, I w-wouldnt you lie.

You pull the tabs on the diapers and the sodden diaper pulls away. You ball it up noticing the weight of how much you filled it. You place it on the ground. You spy another look around and still no one around. Just Lauren and the cold air. You stand nearer the car and Lauren is being polite standing by you to shield your nakedness.

Lauren takes a wipe from the bag first and wipes your bottom. Its not warm, but warmer then the chilled air and you enjoy the reprieve of the chill if even for a moment. She takes another wipe and is about to wipe between your legs when you hold her hands. NO! I got it. You take the wipes and clean diligently between your legs. You enjoy the fine baby powder fresh smell and feel a flush to your privates.

You blush at the arousal in your pussy from the wipe and hope Lauren doesnt notice. You look at her. You curse inwardly, she notices everything. She smiles at the apparent moment of pleasure you gave yourself.

She has laid a mat on the ground, a changing pad. It is a glossy pink.

Where the hell did you get that? You ask.

Oh, ever since weve started playing, Ive bought a few things, replies Lauren.

Id hardly call what we do, playing you murmur and not audible to Lauren.

Come on, diaper time. Lay down

You pause a moment. Fuck it, you say. Youre too cold to fight her. You also rationalize if you lay down you wont be standing naked. You lay on the mat. You dont know to cover your breasts, your vagina, or the blush on your face. You zone out as Lauren starts the process of diapering you. You feel the sprinkle of powder and the scent sets you on a high of sexual ecstasy again. Your clit tingles and engorges and you feel the rush in your vagina. Lauren slips the first diaper under you and tapes it. The warmth of the diaper feels heavenly and you feel some of the chill ebb. You had moment where you believed you had an orgasm but passes in a flash.
Oh God! You think to yourself, Three diapers. What was I thinking?

You automatically go through the next two diapers in a daze. Its when Lauren is pulling up the plastic pants and then the diaper cover you snap back to reality. Reality? You shake your head. Im dressing as a baby with my best friend who enjoys humiliating me as I am dressed. What happened? I lost track of time. Youre standing, when you look down, youre in the pink dress. The plastic bib is tied. The booties are on your feet. You hold up your hands and see the frilly lacey mitts tied with their bows. You glance out of the side of you eye and see the ruff of lace. You slump. The bonnet.

But oh God youre warm. You hug Lauren in thanks.

Okay, Ashie. She pats your bottom and you feel the whump-whump of the obvious quantity of padding.

You slouch. You notice the spread between your legs caused by the mass of diapers. You take a few steps and while you waddle, its not too bad.

You catch the reflection in the car window and see the ponderous butt of ruffles and bow accentuated by the open back of the baby dress. You smile. Im cute. I like this. Im with my best friend and she likes that I dress like this. Its Hello Kitty pink and I hate pink, but yeah, darn it this is cute.

Lauren, you say to catch her attention. She is beaming at you.

What?

Come on, take a pic of us two, you shyly say waving her over.

Lauren bounds the few steps. You smile.  You never noticed how happy she is when she is with you dressed like this. Shes actually glowing with enjoyment. She holds her camera out at arm length, smiles at you then faces the camera. You put your arm around her and pull her close. She kisses you cutely on the cheek and takes the picture.

You make a cute pouty smile as she and you giggle at the picture.

Im a baby, you think to yourself.

Can we go home now, Lauren? you say.

Lauren clicks the key fob and unlocks the door. You rush to sit in the passenger seat. While the dress and dry diapers provided some much needed warmth the car makes that seem arctic. You adjust as many vents as you can to blow warming air on you. You concentrate on the heat warming every inch of you and lose yourself in it. Lauren lets Apollo jump into the back. She climbs into the driver seat.

You notice Lauren is not taking you home. Well, not your home. You realize she is heading to her house.

Lauren, you start to feel a flush of anger, Im not doing¦it¦in front of you!

Youre not, I promised. She grips the wheel. I said I would. Oh wow Ashie, Im so nervous!

Really? You eye her suspiciously.

Ashley, oh my God, my heart is racing. She grabs your hand and holds it to her chest. Through the satin mitt you feel her pounding heart. You also feel the softness of her breast. Before she looks, you pull your hand away and look out the window and feel the blush of your cheek and tingle between your diapered legs.

You wont let him¦hurt me? Lauren asks.

Youre serious? still a tad untrusting.

She pulls over to the side of the road and puts the car in park. She takes your hands, Ashley, I love you. She brings her face close to yours and kisses you. You dont know how to react, but you feel the passion in her kiss. Her hand moves to cup your head and she draws you closer. Your mind races. Im kissing a girl. Im kissing my best friend. You push aside and reservations you have and return the passion she radiates to you and with satin mitted hands gently cup her cheeks and enjoy the kiss.

She pulls away looking you in the eyes. Her smile goes from ear to ear. She blushes. You stare in shock, she actually can blush.

That took a lot to say Ashie, says Lauren putting the car back into drive. Are you okay?

Im, honestly shocked you reply. I didnt expect my best friend to French kiss me. You giggle a little. I didnt think you were a lesbian?

Oh silly baby! Im not. She laughs. Im..um¦you just excite me. Probably the same way Apollo excites you?

Shut up! Thats different.

Do you love me Ashie?

Im confused, I dont know.

Do you love Apollo? When you and he have sex, says Lauren, Is it love or fucking.

Its something different, you realize you dont know what it is and you start to cry. If you love me Lauren why do you humiliate me?

I thought you liked it?

You dont take long to realize you do. You always felt a twinge of sexual excitement when made to be the submissive. Even when made to have sex with Apollo.

Lauren pulls into the long drive way leading up to her house. Such a large property and house. One of the three garage doors opens and Lauren pulls the car in. The doors unlock and she steps out. She opens the back door and Apollo leaps out.

You step out of the car and stagger a bit forgetting you had the bulk of diaper on. You lean on the car roof of the sporty car and say to Lauren, Im not having sex with Apollo in front of you.

Gosh, get over it, youre not.

Lauren grabs your hand and leads you into the opulent house. You gawk at the high ceilings and large open space on the first floor.

Do you want anything before we go upstairs to.. she blushes, you know

Wheres your Mom? you ask. Such a large house and you know only the two of them live here.

Business, shes home tomorrow night. She walks up to you puts her arms around your hips and pulls you close, It just me and you¦Oh she lets you go, and squats down to pet Apollo behind the ears. And you Apollo!

She stands and holds you again. You cant feel it but know she has her hands on the copious diaper.

Im sorry I humiliated you she gives you puppy dog eyes.

You try to hide a smile at her cute expression. No youre not! you chide her

Okay, she giggles and Im not She twirls you in the space. With the abundance of diaper you lose your balancing and spin right into the back of the sofa and role right over the top of it over the cushion and land with a whump on your diapered bum.

Lauren hurries over hopping over the couch  and sees you sitting on your ponderous ruffled butt. You have a pout on your face. Lauren falls back on to the couch laughing hysterical.

Shut up! you pout.

Are you Okay? She asks.

Yes, you meekly say.

Lauren stands tosses you a remote control. Watch cartoons, Ill be right back.

Where are¦ but she is already up the stairs before you can finish.

You fiddle with the remote but the hundred buttons confuse you. Without thinking you crawl to the television and press the on button. You crawl back to the center of the canyon sized room and sit on the floor.

Oh my gooooosssh, you hear Lauren chime from the top of the stairs. That was so adorable watching you crawl

You turn bright red.

Do you do that at home?

No, only when Im being bad. You correct yourself.

Do it again!

NO! you cross your arms.

Come on, she puts her hand up in prayer in front of her, pweeeasse Ashwie!

You get on hands and knees and make a few laps around the large area rug.

That was awesome. She finishes coming down the stairs, that was the cutest thing I have ever seen.

When she comes to the bottom of the stairs you notice what she is wearing. Its a lavender satin babydoll with tap sleeves and little satin bloomers with bows down the center of the crotch. You realize she is a wonderfully curvy woman and feel a flush of passion set your heart racing.

As she approaches you realize the bows in the bloomers are actually securing what would be an open crotch.

Im all ready. She poses with her arms out. What do you think? Huh?  Crotchless panties and everything.

Y-you look, you wet your mouth as you realize it had gone dry, You look beautiful.

She kneels next to you. Hugs you from the side, kisses you on the cheek and says, Oh thank you, so are you!

For the next few hours you two scroll through channels of cartoons, enjoy popcorn, and soda. Most often during the commercials you both would fall back onto the floor and kiss. When it first happened you felt uncomfortable about the girl on girl passion. Youre not into girls. I like boys. But when your hand slipped under her babydoll to cup her breast and her nipple responded by becoming erect for you to massage you admit your pussy did wet.

When the next commercial started you didnt fall back in her embrace.

Ashley? questions Lauren.

Wait a second, you reply squirming on your bottom. You shake your head not believing what youre about to say, Im wet. Its barely a whisper.

Lauren sits up. What?

I wet my diaper, you blush, I need my diaper changed.

Lauren claps. Really!? almost a shout, which echoes in the large space. Can you say it cutesy?

Oh come on, bad enough I just told you I tinkled.

Yeah, and I have the dry diapers you need!

You try to glare but even admit you want to be babied right now. Lauwen, can you pwease change my diapey, I made tinkles.

She claps again, Love it. I would love to wittle Aswie! She stands and you blush feeling the tingle in your clit watching her form as she walks away. She returns, obviously from the car, she has the mat under her arm and the diaper bag. She almost runs and hops into place next to you. With dramatic flourish she unrolls the mat and with both hands points to the mat. Lay down wittle baby!

You smile at how happy Lauren is playing with you. Maybe in this big house she gets lonely. You always have Mommy, Apollo or even Cicero to keep you company. Her Mom travels a lot, and her Dad, well hes not in the picture anymore. You scoot onto the mat. You respond to her gentle requests to raise your butt and she slips off the diaper cover, the plastic pants and the thoroughly soaked diapers. Luckily you wore extra. You notice you went through two layers.

You decide to play and roll over and try to escape. Lauren laughs as you crawl away. She puts her hands on her hips and says, Bad wittle baby Ashie! You get back here. She comes after you and you quicken your pace giggling. Lauren catches up to you and stops you and lightly pats your bottom, faking the spanking.

You get back to you mat you bad baby!

Wah wah, you fake cry and crawl back to the mat and lay back down. Lauren applies some baby oil to her hands and rubs her hands to warm it and rubs it on to your thighs and pussy. The scent excites you and your vagina reacts accordingly. You feel the blood rush. Your clit swells with obvious notice by Lauren.

Ooh, She says.

She dabbles more oil into her hand and rubs your pussy more. The days passion catches up to you in a huge onslaught and your toes curl, your back arches and you cannot hold back the moan and cry as the eruption of orgasm overtakes you.

Lauren falls onto you and kisses you. That was amazing!

Apollo raises his head from the familiar noise of your climax. Lauren sits back up and by the time your orgasm ebbs you have on a fresh diaper and the diaper pants are pulled up.

You look around and notice outside the windows and its dark. Um, its late! you say.

You want to leave? Lauren pouts.

I dont know, Im all confused.

Stay, please, she scoots closer to you. Call your Mom, she says leaning to reach and grab a nearby phone.

You want me to sleepover?

Yes, she says.

You admit you dont want to stop now. Youre having a great time. You grab the handset and dial home.

The conversation is brief and without any trouble your Mommy permits you to stay over Laurens house.

We need to give Apollo a walk, feed him and give him water.

Lauren stands and walks on tip-toes to the kitchen. She bounds with joy. You stand and with only the single diaper on make an easier trip to the kitchen. You feel a twinge watching her strut to the kitchen and she catches you looking when she looks over your shoulder. She reaches for a bowl from a cabinet. As she leans over to fill the bowl youre overcome with a compulsion to touch this woman. You step up behind her and the bulk of your diaper presses against her back side, you reach around her and cup a breast. Her nipple responds acutely. You gently massage it between as best you can in the mitted finger and thumb. You press more of the diaper against her and she responds my moving her hips against it. She leans her head back and looks at you. You kiss her for a moment and then kiss her neck. Your hand slowly goes around her hip and down into her bloomers. She lets out a breath of air.

You have only felt your clit between your hands before. Unsure what to do you do the same thing you would want done and she responds with a pleasurable moan. You feel the swollen clit through the satin mitt. She humps against the bulk of your diaper. She grabs the edges of the counter. Her mouth opens but no sound comes out. You meet each hump of hers with a thrust of your own pressing the diaper firmly into her. Your hands continue to fondle at her breast and clit.

She screams in a shuddering O-oh G-god, Ashley Im cumming! Her whole body tenses against you. Your hand between her legs receives a dousing of cum.

She rests her head on the counter. She seems to enjoy the sense of the cold granite counter for a moment. She lets out a shudder as you slide your hand from between her legs and turn to lean on the counter. You look at your hand and the puddle wet stain in the satin glistens from her cum. I made her cum, I made another girl cum!

Lauren leans heavily on her arm looking at you. That was a first. She says.

She stands and just pecks a quick kiss on your lips. She takes the bowl, the bowl that had been filling in the sink during your whole passionate play “ and sits it on the floor.

Apollo, come here, Lauren coos water for you.

He tilts his head.

You walk up to Apollo and hold out the cum soaked mitt in front of him. He intently sniffs at the hand then huffs having gotten enough walks to the water and laps up the cool drink.

What was that about? Lauren asks.

Um, it um helps if hes familiar with your¦um scent for later!

Oh my she blushes.

You dont want to now? You take the lead and take her hand. You go back to the familiar spot on the living room floor. Im not going to force you to Lauren.

Um, Its not that. She fidgets in place. She lets out a breath. Oh.

You cup her hands realizing the silliness of the satin mitts and chuckle. Can you take these off?

She laughs and undoes the bows. You cup her face in your hands.

She stands and walks to Apollo, she squats down next to him. She starts to scratch his head and he responds by leaning his head on her thigh. She opens the sliding door and steps out, her look conveys you should follow.

Will he run off without the leash? Lauren questions.

Oh God no. Embarrassingly you point at your crotch, And give up this? you chuckle at your suggestive joke.

Apollo runs out the door and after a few yards starts a pursuit of some scent. He wanders around in circles with his head to the ground. He eventually squats and does his business and scratches and continues to wander.

Lauren, what is it? You look her in the eyes, it cannot be worse than anything you have witnessed me doing.

She takes a deep breath. Im a virgin. She says it like shes ashamed.

WHAT?! You exclaim.

Yep, Apollo has lain down and rolls around in the grass then bounds up to lay next to Lauren. She starts to pet his belly. Ive never had sex.

But,

She interrupts, Yeah, all the rumors Ive fucked the football team, teachers, whoever she chuckles Guess Sissy has given me a bad reputation. She gives a dour look then her expression changes to one of joy and she says, Wowwy! You know youre the first person that ever got me to orgasm.

Lauren, you cant¦.your virginity to¦a..dog you put your hand on her leg. You slump and sigh and you really dont want to admit this, Lauren, I love Apollo and he is very pleasurable lover, but this¦

Hey, hey we havent even started yet. She pats your hand. You said you werent going to force me, so¦ she shivers. Its cold, come one lets go back in.

She sidesteps as Apollo leads the way inside. Lauren sits on the space before the television and you sit down beside her. You wiggle a little and have to admit, the bulky diapers were a lot more comfortable to sit on the floor with. Lauren puts her arm around you and you rest your head on her shoulder.

Ah, commercial! Lauren grabs you in an embrace and you both fall back on the floor to passionately kiss. You dont finish when the commercials come to an end and for the next hour you each bring each other to orgasm again. You exploded in ecstasy as in the middle of her rubbing your clit through your diaper she untied the bow on your bonnet and threw it to the side to get a handful of hair and hold you for a deep probing kiss.

Her orgasm again had her cry out when you sucked on her erect nipple and she was pinching and stretching her clit between her fingers.
