Ginny slowly blinked her eyes open and stretched. She looked at Lavender and Hermione who were sleeping next to her on the floor. Then she remembered she was wearing a diaper and reached down to touch her butt. She was surprised at the amount of poop that was in it. She sat up and cringed as the huge load squished around her bottom, then realized she kind of liked the feeling. She wiggled around in it, smearing it all over her diapered area. She took a glance at Lavender, whose diaper appeared equally messy, and then at Hermione's, whose diaper looked like it could still hold more. Well, thought Ginny, I can fix that. The red-haired witch leaned over the sleeping Hermione and pulled her shirt up a little, exposing the girl's belly. She put her hands on Hermione's belly slowly as not to wake her. Then she moved them around softly, gently massaging the brown-haired girl's abdomen. Hermione giggled in her sleep, and to Ginny's surprise, released her bladder into the diaper in response to the tickling sensation. Ginny found herself reaching down and feeling the warmth rush in to the garment. If a simple tickling can make her wet herself, the ginger thought, what can I make her do with this? She put both hands on Hermione's belly and pushed down hard. Hermione sat up with a gasp at the same time as an extremely loud fart and load of poop shot out of her butt. She looked at Ginny, who was blushing profusely. "Ginny? What are you doing?" The redhead stammered, "I, I- I just-" Then they heard a yawn and saw Lavender wake up and sniff the air. Her nose immediately wrinkled. "I don't know about you guys, but it smells like we all need a change." Seeing as Hermione had sort of designated herself as official diaper changer, she set to work on Lavender, who kicked her legs around and laughed, obviously still enjoying the baby game. It was Ginny's turn next, and her butt was covered in poop from her previous fun. Lavender laughed. "Geez, Gin, what'd you do, sit in it?" Ginny didn't answer. When both girls were done, Hermione looked down at her diaper. "It would seem as if I need a change as well, anyone up?" Lavender sniffed Hermione's diaper. "Whoooee, you won't get me anywhere near that thing!" Hermione sighed. "Guess I'll do it myself then," and she promptly stripped the diaper off of her body and wiped herself down. Lavender was still looking at the soiled thing on the floor. "Wow, Hermione, you were messier than the both of us combined!" Hermione glanced at Ginny and said, "I had help." Ginny couldn't tell whether Hermione was angry or not. Then the three girls noticed someone was missing. Sometime either while they wer sleeping or changing, Parvati had left the room.
