You cum quickly like a good girl.

zzzzZZZZZZzzzZZZzZZZZZZZZZZZZZZzzzzZZZZZZZZZZZ... CRAAAAAAAAAACKLE!

"AAAAAAAAAAAaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaarrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrgh!"

All of you scream as a sizzling crackle of electricity fires off into your nipples. Through the blinding pain you are hardly aware of the desperate looks you are getting from your sister slaves. All the girls are praying for you to cum and release them from their torment. Mistress Jade's fingers continue to batter your clit as you ride out the shocks. Until they current suddenly stops!

"Pleease..." Areli desperately gasps, "Yoshino... please... focus..."

Your knees buckle under Mistress Jade's cruel smile. The whining sound returns alerting you of the impending charges...

zzzzzzzzzzzZzZZzZZZZZzZZZZZZZZzZZZZZZZZZZZZZZZZZZZZZZZZ... sizzzzzle CRACK!

Your mistress hugs your little waist preventing you from struggling away. Her fingers continue to roughly stroke your little clit. The violent shocks to your nipples are too much...

You cum... hard within her grasp.

"Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!"

You aren't sure if the screams you hear are your own ecstasy or the desperate cries of your sisters suffering their punishment. Your core muscles cramp with the intensity of your orgasm. Somehow you have succeeded.

The shocks stop abruptly and Mistress Jade chuckles. You still are desperate for her approval despite the cruelness of your punishment.
