-NOT EDITED-

Eric smirked as Ann came, moaning over and over about how much she loved her diaper. Her moans were mixes embarrassment and pleasure, and he couldn't help but love how they sounded. He knew it was wrong, but he was only a year older then her and had only known her for 3 years. He only called her "little sister" because he's foster parents wanted him to, they thought it would help them get along. He had to admit she was gorgeous, and adorable. He knew it couldn't happen but his dick however, didn't. He ignored his own disturbing thoughts and focused on her.

"That's it, what a naughty little baby, cumming all over your diaper, you must really love being a pathetic little baby."

Ann couldn't help it, when she finished she fell against his chest. Her diapered butt sticking up and her dignity completely in tatters. She felt his hand rub her back and then go down to her diaper and pat the wet, messy and now cum fulled diaper. She had to admit, it felt good. She felt him grab the waist band of the diaper and squealed knowing exactly what he was about to do.

"No no no no eric no, please, don't!"

But she just felt hun chuckle has he pulled the back of her diaper up, giving her a wedgie and spreading the mess back in her ass and between her checks.

Laughing, Eric watched her squirm in her own mess.

"Aww does the wittle messy baby like her mushy diaper wedgie". And as embarrassed as she was, Eric knew she liked it. She knew she liked it, although she would never admit it to him.

"No, Eric gross"

And that's when she knew she messed up.
