ARM-801 "Stick your tongue in as deep as possible" is the company rule of Anus Licking Inc.

Tongues thrust in like they're sucking something out, thick, flashy, and unparalleled anal licking by five women! Working sisters x Aroma project... As a result of the work style reform in the Reiwa era, such a wonderful company was born. Each female employee brings their tongue technique to the max, lively performing anal licking... That is our company's raison d'etre. This is what happens when carnivorous women are released into society.
