Anny was left tied up in the kitchen by M and F, who had to go outside for a while.
Akemi realizes they are alone and takes advantage of the situation to humiliate the submissive Anny, ordering her to lick her armpits. Anny responds to Akemi's requests with the hope that she will release her, but Akemi doesn't even think about it.
Anny's tongue works on Akemy's armpits, which by the way are beautiful armpits!
Akemi better not let the guys know what she did to Anny, because the punishment will be great if they find out!
