It's Sunday afternoon and Kim wants to be a little girl and has decided it's dress up time. She is relaxing on the bed with her boyfriend, blue fairy wings on her back, diaper on under her dress and her pacifier in her mouth, playing with a puzzle book. She's searching hard for the red crayon, but can't seem to find it. The first part of this movie is all about what it's like when your girlfriend is a cute big baby. Basically they mostly want to play, and as a Daddy you have to indulge their little girl side.

But watching her act like a baby is turning him on, and eventually he asks "Why don't you take a break and come over here?" She turns around, revealing her diaper, and then her gets her to come sit on his legs, and it's easy to see his hard cock through his jeans. He lifts up her dress, and asks if she's dry. Discovering she is, he decides it's time to have some fun, bouncing her up and down until she has an accident. All little girls love bouncing up and down, and Kim is clearly having a fun time and can't stop giggling and laughing.

Kim's boyfriend is also obviously enjoying having his baby girl bouncing up and down on his cock, and keeps making little jokes to make her laugh harder and harder so she has to pee. This is a really fun part of the movie, watching Kim trying not to laugh, hands over her face, but continually cracking up. This is without a doubt the kind of fun game I'm sure everyone would love to play with their baby girl.

All the bouncing does eventually take it's toll though on Kim's bladder, and soon she really does need to pee. In the face of more bouncing, resistance is useless, so she gives in to the inevitable. Sitting there on her boyfriend's hard cock, dress pulled up at the front and with a loud audible hissing sound, Kim finally wets herself. The yellow stain creeps slowly up the front of her diaper and the warmth around her pussy must feel wonderful. It must feel wonderful for her boyfriend too, as there's no doubt he can feel the warmth, even through his jeans.

But then there's another unexpected sound, more like a fart and a squelchy pooping sound, and Kim resumes bouncing up and down. "You did more than just pee didn't you?" he asks. "Daddy liks that." Kim just giggles in reply. He undoes his jeans so he can feel her now wet and poopy diaper directly on his cock. With warm pee and a poop in her diaper, Kim is obviously feeling turned on too, as without being asked, she pulls the legband of her diaper aside and with both hands guides his stiff cock past it and into her waiting pussy.

Then it's back to the bouncing game, only this time Kim is actually being fucked at the same time! Kim moans more and more with pleasure, her diaper crinkles loudly, and eventually they both cum. At one point the diaper is opened, revealing Kim's pussy sitting against the yellow pee stained diaper. Then she lifts up her butt, also revealing the poopy mess at the back of her diaper and proof of her sexual arousal with girl cum extending from her pussy!

The dirty diaper is removed and Kim helps guide his cock back into her pussy, and they resume fucking. The movie ends with Kim turning around to display her gorgeous poop covered ass and with her boyfriend's cock snuggled into her butt crack and at the entrance to her pussy. Very sexy!
