Honoka slowly but surely drained Nozomi's breast, feeling the comforts of childhood come back to her. "Mmm, feels like I'm right next to Mommy... Mama..."

As Honoka drank from her, Nozomi noticed something odd. She thought her eyes were playing tricks on her but eventually too much was happening for it to be an illusion - Honoka was regressing, now a 6-year-old girl just about to enter school for the first time. "I don't know how young she'll get; I need to get her off my breast!"

"C-Come on sweetie... You can stop now..." Nozomi stammered. 

As Nozomi reached down to Honoka's young sucking mouth, she couldn't seem to get her to stop suckling... Honoka had aged down at an extreme rate, now looking like an infant.

A sudden jolt went through Nozomi, preventing her from being able to unlatch Honoka from her breast. Honoka stopped shrinking around six months, popping off of her breast and falling asleep, although still slightly wriggling.

"O-Oh my God... Honoka's a baby now..." Umi was shocked at what she saw, unable to fully believe it.

"Wow, Rin's not sure what's going on... but Hono-chin's a cute baby, nya~" Even though Rin had an equally shocked look on her face, the small smile indicated she wasn't as bothered by this as others.

"Th-There's gotta be some way we can change this? I mean, Honoka's not going to have to grow up again, right?" Maki had burst out of her chair, the doctor's daughter on the verge of freaking out.

"I-I'm not sure..." Nozomi looked down at the tiny, orange-haired bundle in her arms, resting peacefully against her new mommy's breasts.
