Competition

As you lead the three girls into the room, you gesture them into a kneeling position beside Lia, Mina and Jisoo
"We'll have a competition girls. Momo and Somi, detach your equipment and put it beside you. We'll be having a competition. On your back and spread eagle girls."
As you said that, they said, "Yes Master"
All the girls got the position you asked them to be in, and then you went to put a beaker in front of all of them.
"You girls have to jack yourself off into these beakers. Whoever squirts the most in 2 minutes gets the role of my enforcer, while the other 5 will have to break the 5 yet to be broken"

The girls then began to finger and rub themselves, with moans galore, all while the 5 still unbroken watched in horror as they tried to comprehend the sight in front of them, all while tied in a restrictive position and being tortured with a vibrator, the puddles below them indicate some of them had cum already.
