"Oh really? But I... have always been in love with you, Senpai."

When the protagonist broke up with her ex-boyfriend, he told her she was "frigid." Since then, she has been worrying whether that is true.
One day, her kouhai at work, Azuma-kun, accidentally saw her smartphone, and the page displayed on the screen was on sexual frigidity.
To keep his mouth shut, the protagonist brings him to an izakaya and drinks so much that she reveals her past with her ex to him...

"Is there anything I could help you with?"
"...If Azuma-kun could help me solve my problem, I'd gladly ask you to help, but... I don't think you could..."
is what she said, but for some reason, the opportunity came much earlier than expected...?!

Being completely different from his usual earnest and friendly self, Azuma caresses his senpai with a poker face and makes her cum continuously and effortlessly.

"Senpai, you're not frigid at all. If anything, you're way more sensitive than you think."
"You'll cum so much you'll never wonder again whether you're frigid or not. I'll lead you to orgasm many times with my hand. So cum a lot, okay?"

This is an erotic comedy featuring a kouhai with a hidden face and a senpai who is a closet pervert!
