Cat Girl - キーボードバシバシ

catgirls actually acting cat-like is excellent

Translation from your friendly neighborhood weeb:
Title: "Keyboard bashi-bashi* "
First panel: writing writing
Second panel:
sfx: bashi-bashi*
the guy: "Wha-! Cut that out!"

*TL note: bashi-bashi is basically the sound effect / action of striking the keyboard.
