Reitetsu na Toshi no Josei Kugusuguri Tsudzukeete Tachiba Gyakuten Suru Hanashi

Our hero has taken up jujutsu, but there's a younger instructor there who shows him absolutely no respect despite his age.

When he's finally had enough, he captures her and decides to give her a ticklish lesson in respect...

but he doesn't count on the tables being turned...

A game where hard tickling is the main focus.
