“Assistant! Look at this!”
“What did you do this time?”
“This medicine…”
While we were having this conversation, I looked at my senior in a lab coat as he mixed a suspicious medicine.
Niizuma Sae, the cute red-haired head of the chemistry department.
She has a genius mind that is uncharacteristic of ●●●, and is a senior with the temperament of a mad scientist who often mixes medicines.
I was attracted to a senior who was very particular about what he liked, but by some chance, he found out about my penchant for super-huge breasts…
“Hey, assistant…do you like big breasts like this?”
“yes……”
“I-I understand, assistant! Leave it to me!”
A lovey-dovey story about growing breasts that begins with those words.
