STORY
Protagonist Eiji was struggling through his math exam.
He filled in the blanks without a clue.
After a while, Ms. Shoko came into the room.
She was gorgeous, early 30s, a young mother, and Eiji's fantasy girlfriend.
Unhappy just wanking to her in his mind, he dreamed of ways to do more.

Maybe it was luck or fate, but that day as when everything changed...
