Ryouta was an average salary worker. For the last 4 years he'd labored
thanklessly under the management of his boss, Ms Ayaka Takami, as a
designer of brassieres for women's lingerie maker Dejour.
When he got the chance to design part of the season's main
product line, it was offered with Takami's usual coldness:
"You. Can you make a J-cup bra?"
It was a backhanded offer, as there was nobody who would buy such a size.
But with few prospects for advancement and nothing to lose, Ryouta went for it.
"I'll do it!"
"Of course we can't afford product testing. You'll have a budget of about $100."
"But--"
"This isn't a hot seller. We can't waste more than we expect to earn back."
"But--"
As Ryouta's spirits tumbled he was introduced to his design partner.
As soon as he saw her, they both let out a surprised gasp.
"Ah!"
"Ah!"
Before him stood his old senpai from college. Shiori Houjou. For the longest time he'd
had a one-sided crush on her. She went off and got married. Ryouta never
forgot her incredible breasts, regal and large. The biggest he'd ever seen.
