Sorbet, Soba, Lyra and few trainees are about to experience the
same training that humans in the past used to train wolf girls to become
sled wolves. Wolf girls are not easy to catch and they are stronger and
more agile than the average human. The suit and the devices were
designed for making captured girls feel helpless and easy to control. The
one who wields the controller for the vibrators, can bring even the fiercest
beast girl to her knees and tame her.

One by one the trainee girls begun squirming and making weird noises,
No way to remove the suit or the device themselves, the girls are becoming anxious, After Lyra's and Sorbet's turn Soba was next, she tries to
negotiate to avoid getting vibed, but she fails....

Tried to write a little story give this more context. xD
I'd imagine that humans study the girls' personalities and reactions to train them more effectively.
I would wanna try to make a sled wolf side story comic and bring more details to this theme. Perhaps after I have finished first chapters of the main story of Sorbet. ^^*
