I Want to Make My Condescending Boss Squeal Like a Boy

The protagonist, Fukuda, is a woman who wants to make domineering men cry.
Her target this time is her boss, Koga.
She plans to invite him to another drinking session at her place and then make her mean, condescending boss admit defeat pathetically.
However... when she wakes up the following morning, she realizes that she doesn't remember anything about last night's sex!

Undaunted, Fukuda invites him to have sex again, but Koga seems dissatisfied, for some reason...

"Hey, why are you acting like a sadist during only foreplay, huh?"
"Huh?"
