Aleisha is asleep in bed when her house mate Danni comes in to wake her up and remind her it's her Mom's birthday. Aleisha is reluctant to get up, so Danni perseveres and pulls the covers off her. Imagine her surprise when she discovers that Aleisha is wearing a diaper! But Danni is fascinated and wants to know more, questioning Aleisha whether she wets in her sleep and if she does it every night. Aleisha is clearly embarrassed, but does see the funny side too when Danni keeps trying to pull the covers off to get a better look.

Danni checks and discovers that Aleisha's diaper is dry, but still teases her about it, and then dares her to poop in it, not thinking she'd do such a thing. Aleisha retorts that she's happy to take on the dare, and that she poops her diaper all the time, and will do it right there to prove it. Danni of course doesn't believe her, but she'll soon find out that Aleisha is serious!

First Aleisha untapes the diaper to show there is nothing there yet. Danni asks again if it's true that she poops her diaper regularly, and guesses immediately that the thought of doing it is making Aleisha horny. They chat about Aleisha's love for diapers and why she's kept it a big secret, since she already knows other intimate things about Aleisha, including when she's fucking guys. Danni does think Aleisha looks cute in her diaper though, and asks her put her hand down the front. Aleisha gives her pussy a little rub, while Danni tells her how sexy she looks, but still she doesn't believe Aleisha would poop in it.

So Aleisha gets on her hands and knees on the bed, first farting and then pooping a bit into her diaper. At first it's not much, and Danni wants to see her do more, even admitting she's finding it satisfying to watch. Aleisha paces beside the bed and then squats. She tries to poop more, but still Danni is not happy that it's enough. "I dare you. You need to poop more. This is nothing. I want a BIG mess!"

Aleisha agrees. Bending over in front of the mirror, admiring herself and with her butt poking out, she grunts and groans. Wonderful squelching noises emanate from her butt as she fills her diaper full, this time with a lovely big mess! Aleisha admires her poopy diaper in the mirror again, as Danni instructs her to mash the poop all over her butt. Aleisha is then furher instructed to sit down on the floor and open the diaper, and she sits there with her legs apart, her butt in the mess, and a big smile on her face!

Despite her protests as to the smell, after what she's just seen, it starts to seem like maybe Danni is getting a bit horny too. She even puts her hand inside Aleisah's diaper and gets poop on her fingers. But there is no doubt whatsoever that Aleisha is turned on, as she rubs her pussy through the dirty diaper right in front of her friend. Then Danni has an idea, and gets Aleisha to smear her poopy butt all over the closet mirror. It's clear that both girls are having fun, as Danni then says she wants to see Aleisha cum! "I want you to cum. Finish for me!"

So Aleisha goes back to rubbing herself, but Danni joins the fun to, putting some more poop on her fingers and smearing it on Aleisha's nipples! And a "B" for bitch on her tummy! It's just part of the fun though, and just how young girls tease and talk to each other. It's the playful interaction between the two girls that is part of the fun and appeal of this movie.

Danni leaves the room briefly to wash her hands, but Aleisha is clearly not done yet. She totally filthy and still needs to cum. She sits on a low chest of drawers, and with her poop smeared breasts exposed, she masturbates like fury through her diaper and then directly on her clit! But oops, it looks like her Mom might have arrived!
