let's do some exercise

You walk back to the girls still waiting in line. you sit next to Miss Helga and smile. Leisurely you say: "We are in the gym so let's do some exercise... turn left and start running." the girls start running being followed by your gaze and the relentless eye of the camera.
You see how the redhead walks funny because of the plug in her ass. You see Tina running hard because it helps her to keep the heavy toys in her pussy and ass. And you see the brunette biting her lip as the chain bounces up and down and by that pulling on the nipple clamps.
"Girls, please remove your bra's" Tina and the redhead stop for a moment to remove their bra. "Did I say you could stop? Run!" they start running again and remove their bras while running. When they pass you they throw their bra's into your lap. You are amused, they are really getting into the mood now...
They aren't the only one you look at three pairs of titties bouncing while the girls are running. Your already rock-hard cock get's even harder if that is at all possible. They might have to fuck with you soon, but first a little more fun.
"Stop running, please remove your panties and stand in front of the vibrators now." they obey. You turn on the vibrators and say they will have to do pushups now. They position themselves over the vibrators and start doing pushups. Each time they get on the ground their clit is stimulated making it harder to get up again.
You watch the girls shudder in pleasure each time their clits hit the vibrators making it harder to get up again.
It isn't long before the girls can't get up anymore. they start pushing their clits into the vibrators. Moans escape from their mouths as they start to cum. their bodies tensing on the floor their heads turning red in excitement.

After having watched them for a while you now feel it is enough. "Please remove your toys and stand in line again." After they regain their senses they comply and stand up again albeit a little shaky. "You have made me quite horny so I think I deserve some compensation from the three of you..."
