Breast Milk As A Secret Ingredient In Sweets Adventure

Introduction

A super popular "Extra Special Pudding" with only 200 made each day!
What is the secret to its flavor?!
The one who devised its recipe is Konomi,
the older sister of the Shirasago family.
She loves making sweets, though she may be somewhat capricious.
The secret nestling within that recipe is something only she and I know... Rather than using milk, Konomi uses her own breast milk!
("Wait... does that mean I drank Konomi's... breast milk?!")
And in time, maybe I'll drink Mitsuna and Ouka's milk too...?!

Story

The confectionery Hexenhaus's popularity with girls has been soaring recently.
Their Extra Special Pudding has become a hit overnight, selling out every day right after their doors open!
The main character of this story, Ikuya Rikumaru, had gotten wind of those rumors as well.
However, the reason he becomes in Hexenhaus is for an entirely different reason...
That reason was a cute girl in a confectioner's outfit that he spots from outside the shop.
Sneaking away from his friends, he enters the shop so that he can get to know her better,
and is greeted with a smile by the object of his affection-the manager of Hexenhaus, Konomi Shirasago.
Though her very straightforward way of speech is startling,
he somehow finds himself eating her store's most popular item, their "Extra Special Pudding."
As he is completely overcome by its delectable flavor, Mitsuna Shirasago appears to switch
with Konomi, who has just disappeared back into the kitchen.
Mitsuna deftly works the register and packages everything, all the while chowing down on sweets in front of her customers.
When the other customers leave, she comes to chat with him and, with her honeyed words, convinces him to help out around the store.
When he asks about why, she says that they've become really popular and suddenly really need another person!
Fortunately, his naturally dexterous hands catch the girls' attention.
Coming out from the back of the store, Ouka Shirasago also finds promise in his abilities,
and it is quickly decided that he will start working there!
The very lucky main character, having effortlessly become able to work with Konomi,
comes a step closer to fulfilling his hidden goal. (Yay!)
Some time passes after he begins work there,
and one day, he decides to come into work extra early without telling anyone so that he can impress them.
When he does, he finds a certain girl grappling with a particular issue in the kitchen.
It is then and there that he finds out just what the secret ingredient in that Extra Special Pudding is.

Staff

Older Sister
Naive, Air-Headed & Loves Making Sweets
I've already exceeded the necessary ten thousand hours needed to become a pro!
Konomi Shirasago
Height: 5'2"
Bust: 45 inches
Hexenhaus's manager and confectioner.
She has a deep appreciation for sweets
and compromises nothing when making them.
Because of that, she is very strict with the main character when he works in the kitchen.
However, she is actually a very cheerful and pure person, always saying exactly what's on her mind.
She sometimes reveals just how absent-minded she is and ends up believing whatever incorrect information regarding sex the main character tells her.

Younger Sister
The Sharp-Tongued, Calculating & Good With Customers
Ikuya said he's gonna become our ideal servant and accepts stuff other than cash for payment!
Mitsuna Shirasago
Height: 5'1"
Bust: 41 inches
The shop attendant at Hexenhaus.
Her customer service skills are stellar, and she is very proficient at working the register and wrapping up their products.
The staff trusts her greatly since she can deal with customers quickly and efficiently.
She always tries to eat what they're selling and gets yelled at by her older sister, though.
Because she's a fast thinker and has a silver tongue, she's able to play with the main character like a puppet on strings.

Mother
Doting, Seductive & Loves Drinking
How can you call yourself a man if you won't help out a girl in need?!
Ouka Shirasago
Height: 5'3"

A kind mother who treasures her daughters, Konomi and Mitsuna.
Her work mostly consists of dealing with the important but unseen management aspects of the shop.
She half-forcibly invites the main character and his skilled fingers to join the Hexenhaus staff.
She works together with her daughters to both tease and indulge the main character.
Her one tiny flaw is perhaps that she is pretty shameless when drunk.
