Caireen is in her diaper, crawling around in her room and finds her step-mommy's vibrator. She doesn't know what it is but it looks like a toy so she swings it around and pushes the buttons. All of a sudden, it starts to shake! "Oh!" cries Caireen and throws it back on the ground. But then she starts to play with it a little. It feels nice on her nipples. Mmm, it feels nice on her diaper too! She rubs the vibrator over her diaper and under the diaper on her pussy until she cums.
