Diane could feel something changing, although she wasn't sure what it was. She looked over at Rebecca and saw that she was returning to her normal size again. Diane already knew what was coming next, and cringed at the thought of being forced to endure the humiliation of being made a baby.
However, Rebecca did nothing to Diane once she returned to her normal size. Instead, she just stared at her with a blank look on her face. Then her shirt vanished, and then her bra followed, leaving her topless and her C cup breasts fully exposed. Then her shoes and socks, as well as her skirt, followed, exposing a large diaper underneath. Rebecca suddenly wobbled, then fell down on her ass and gurgled, a small line of drool escaping from her mouth.
"It serves you right, you little bitch," sneered Diane, not noticing that she was undergoing the same transformation as the 17 year old baby until she felt a breeze on her chest. She gasped and noticed that she was naked except for a diaper underneath. Then her mind got hazy. Diane knew that she was becoming stupider, but there was nothing she could do to stop it. Within a few seconds, she had the same blank look on her face as Rebecca, and started sucking on her thumb.
"Tsk, tsk, tsk, Rebecca dear," came a voice from around the corner. Both girls turned instinctively and saw the man from the mall, Rebecca's father. "If you're going to be so incompetent, I'll simply leave you both like this." He then grabbed both girls by the arms and all three of them disappeared in a wisp of smoke. In moments, they were inside his house.
"Now I've arranged a special playroom for the both of you. And don't worry about your parents coming to pick you up, they don't know you exist anymore." And he led them up a small flight of stairs, both girls wobbling at their knees and their breasts bouncing. "And just so you don't get lonely, I've brought some company to play with you."
He opened a door, and inside was a large playroom where they found April, Bets, and Chastity, all three of them wearing only diapers. April was playing with some building blocks, Chastity was shaking a baby rattle, and Bets was watching Barney, clapping happily. "Now you girls play nicely, I'll be back to check on you in a few minutes." And with that, he set down his newest acquisitions in the middle of the room and left, closing the door behind him.
