Sex with a virgin graduate, an extended game - The boss's caresses don't end after one night.

“Did you learn anything after just one session?”
What...? Am I not experienced enough? Is this an extension of our relationship?
Wakana, an employee with zero experience in love, was troubled by the extraordinarily large hurdle of being a "virgin".
One night, when Wakana happened to help Tachibana, the chief of the company, who was being courted by a woman, she said to him, "I want to do something for you.
When Tachibana says, "I want to do something for you," Wakana says, "Please give me your virginity."
The first touch of a man's tongue and his body heat... Every time his fingers carefully touch her, her whole body goes numb... and she feels like she wants more!
"Tachibana-san's voice makes me feel full..." It's my first time having sex and I'm climaxing for so long...!? Liar...I'm not sure what more you can do to me...?
