Don't mix them, Tameike Goro's craziest exclusive duo finally appears together!! ! An unmanned sales outlet in the countryside where long lines form. Run by close sisters Kanae and Futaba, who moved from the city, the store harbors a nasty secret... They pinch each other with their sweaty bodies, and lick each other's entire bodies with tongues dripping with saliva... The beautiful but insane sisters gang-rape each other, forcing them to ejaculate 20 times in a row! Inspired by each other's insanity, the two reach a max level of insanity that they couldn't achieve alone, resulting in a massive 200-minute, extremely vulgar, and extremely controversial slut orgy!
