You and Doe look at each other, and then you grin. Doe smiles back and you head over to Michelle. Heather hands you the pile of sex-toys and you examine them. Among them are a few butt-plugs, a lot of vibrators and a few dildos in various sizes.
You pick up one of the vibrators. It's pink and has a small controller with a dial labeled 'Intensity', ranging from one to ten. Along with the vibrator is an attached penetration device. The fake penis goes into her vagina while the vibrator is touching her clit.
"I usually use five, maximum six with that one. It's pretty strong," says Heather from behind you, laughing.
You smile at her and flip the dial up. It makes a low humming noise and starts vibrating in your hand. As you turn it higher, the humming turns to a whine, until you reach the maximum. You turn it off.
"She's going to have fun with that," says Doe, "I sure wouldn't be able to take it that high."
Michelle starts pleading with you as you turn towards her. "No, please John! C'mon! That's really cruel, can you punish me some way else?"
Her pleading gets more and more frantic as you reach over and place the vibrator against her legs. She clamps them shut, and the prefects pry them open. She starts writhing as she pleads. Finally you can't stand it anymore, and take off your shirt and stuff a bit of it into her mouth. You tie the rest of it around her head, keeping it in place. She can still breathe easily, but she can't say anything now.
You move the vibrator and push the penis head deep into her vagina. When it is in fully, the vibrator part rests against her clit. You motion for the girls to let go of her legs. You haven't turned it on yet, but Michelle starts trying to push the dildo/vibrator out with her legs, squirming on the floor. She can't move it a bit. The prefects pry her legs open again and this time you turn the vibrator up all the way!
