Jessie loaned a dress to her step-sister and her step-sister never gave it back. She's not really snooping through her step-sister's stuff, she just needs to find it! She goes to the cupboard and looks through, not finding her dress, but finding a lot of nice ones that she might borrow. Then, she lifts up a t-shirt and uderneath is something very strange - a pack of adult diapers!

She pulls the diapers out and underneath is something even more personal - her step-sister's diary! Maybe there's something in the diary about the diapers! Jessie feels bad, but she can't help herself! Sitting on the bed, she pages through the diary, her eyes growing wider with every word! The diary says that her step-sister has been wearing diapers for a long time, p*eing and in them every day!

Jessie's kind of horrified! Her step-sister is not a b*by, why does she wear diapers? Reading on, she finds that her step-sister actaully plays with herself in her messy diapers! It's not just a medical problem, her step-sister has a d*aper fetish! Jessie's first instinct is to c*ll her step-mother and tell her what's been going on, but just as she starts to dial, she has second thoughts...

She's imagining what wearing a d*aper might feel like, and it's making her p*ssy tingle a l*ttle. She reads more of the dirty stories in the diary, and they are turning her on! Maybe she can put one on and see what the fuss is about?

Opening the d*aper, she's surprised by how soft it is. She runs her fingers across the padding inside and then slips off her panties. She slides the soft d*aper between her legs and does the tapes up nice and tight. Mmmmm, wearing a d*aper feels VERY nice! No wonder her step-sister likes it so much!

Jessie starts to touch herself through the d*aper.She lays back on the bed and rubs her dripping p*ssy through the thick lining. Feeling her throbbing p*ssy through the d*aper is amazing, but she thinks she knows how it might feel better.

Stepping into the bathroom, Jessie leans against the sink and starts to push. Right away, a huge gush of farts and runny phewp fills the d*aper! You can hear the d*aper filling up, cr*cking as the dirty mess spreads out inside. Oh yes, that feels amazing! The weight of the mess inside makes the d*aper hang low between her legs. Jessie puts one leg up on the toilet and starts to frantically rub her dripping p*ssy through the messy d*aper!

Pulling the legband open, she tries to peer inside to see how full her d*aper is. She rubs the dirty bulge in the back of her d*aper as it hangs low and heavy. She squeezes the load inside, mushing the mess all over her d*aper and her dirty *ss. Thrusting a hand inside, feeling the very messy contents of her totally loaded d*aper!

Jessie is one very, very dirty girl!
