(MC POV)
After that proud declaration from Tsuki, we returned back to class just as the bell started to ring.
"Tsuki-chan… I might be imagining things but… Did your breasts get bigger?" Maeda asked, looking pointedly at my little sister's chest area.
She smirked, "Hehehe~ I had a growth spurt and it's a cup size bigger than before! Jealous?"
I did my best to keep my face neutral and pretended not to hear them.
I caught Nishimura glancing towards Tsuki's direction, his eyes widening for a moment, before quickly turning away and pretending he did not hear nor see anything as well.
"Heeeeh~ I'm definitely jealous," Fujiwara groaned, looking down at her own chest. "Did you do something special to make them get bigger?"
Tsuki's eyes gleamed, her eyes darting to me for a moment before returning back to her friends.
No, Tsuki, don't say it...
"Fufufu~ It's all thanks to Aniue!"
"""Eh?"""
