Leah woke up with something in her mouth, but it wasn't her pacifier. She opened her eyes and found herself face-to-face with a bare breast! She unlatched from the nipple she was drinking from and stared up at the owner of the breasts: Tina.
"Oh, you woke up," Tina said. She guided her nipple back into Leah's mouth. "Finish with your breakfast, and then you can get dressed for school, okay?"
To Leah's surprise, new instincts from this latest warp took over. She obediently suckled from her stepmother's breast, then the other one. While she was nursing from Tina's other breast, she let out a loud fart. This was closely followed by a massive poopy in her surprisingly still clean diaper. Tina didn't bat an eye at Leah pooping on her lap, merely commented that Leah would have to change her diaper before she got dressed.
Once Leah's tummy was full, she let go. Tina set Leah on the floor of her room, which now had a chair in the corner, presumably for breastfeeding sessions, and patted her head.
"Sorry I started nursing you before you woke up. I was pretty much bursting."
"It's okay," Leah said, still dazed from what just happened.
"All right, get ready for the day. The bus will be here in half an hour." Tina left Leah's room. Leah stood in her dirty diaper for a few minutes, trying to decide how she felt about apparently now being breastfed. Definitely not as positive as the other warps, but not negative, either, now that the shock had worn off. It was certainly tasty...
Leah changed her diaper and got dressed in her school uniform, which now included a matching diaper cover. She grabbed her backpack, which resembled a diaper bag with back straps, and headed downstairs.
Tina was in the kitchen, packing a lunch for Leah. Leah watched her regular sort of food, sandwiches and chips, go into the lunchbox, as well as what had to be a baby bottle full of Tina's breastmilk. Clearly, Tina had caused a warp by either thinking she'd like to nurse Leah or that Leah looked young enough to not be fully weaned.
Leah took the lunchbox from Tina with a smile. But she was still confused. She didn't yet know the in-universe explanation for why she was now being nursed by Tina, and whether it was something that applied to everyone her size, all minors her size, or just her.
