After a morning of fighting over who gets what toy, lots of teasing, and sticking tongues out at each other, mama decides you need some help getting along with her new friend's little girl.
"On your knees, both of you. Legs apart and face each other."
"Nuh uh! She was the one who--"
"I don't care who started it, you both need to learn how to play nice!" mama says, cutting off the simultaneous whining. "Now girls, hold each other's hands."
You hesitate, but after a glare from mama you slowly reach for your playmate's hands. She does the same and you two awkwardly interlock your fingers, pressing your palms together. You refuse to make eye contact, but can't tell if it's out of petty rivalry or embarrassment. You look up at mama instead and pout. The position she has you in makes it impossible to clench your legs together, suddenly making you aware of a pressure building in your tummy.
"Aww, there's my sweet girls" mama coos. "Mama wants you to get along with your new playmate. You're going to kiss each other until both of you use your diapers"
You both look at each other wide-eyed, deeply blushing. You both slowly start to move closer before you close your eyes and touch your lips to hers. Her lips are soft and work their way around your own. Didn't she stick her tongue out at you earlier? Maybe you should repay her for that! You push your tongue into her mouth and she whimpers around it before slipping her own into yours. Before long you're drooling over yourself, soaking the front of your dress.
Her hands clench tighter around your own as her breathing becomes more strained. Your heart races at her telltale signs of messing, prompting you to start pushing too. With little effort you release both your bladder and messies into your diaper, making it sag between your legs. Your playmate's diaper is in a similar condition now too, an audible hissing coming from her saggy padding as the wetness indicator quickly changes color. The warm, squishy padding wiped your brain of any thoughts other than getting off with your new playmate. You're far too worked up to remember her teasing or arguing, or even that you're allowed to stop now.
With a satisfied smile, mama goes back to her book. The girls seem to be having fun, why interrupt? They can have changies later once they're all tuckered out~
