An orgasm, pain and a discovery

You trip pretty much as soon as the treadmill and the vibrator are turned on at the same time. Struggling to take quick steps in your ridiculous heels you lose your balance and you're soon hanging in the harness, screaming into the gag in pain. Your weight has pulled the loops around your tits much tighter, making them bulge outward like tight water filled balloons.

You scream into the gag for some time while trying to find your footing again, your vision obscured by tears from the sudden and immense pain in your breasts. "get on your feet bitch!" yells the woman behind you, relentlessly hitting your exposed ass with alternating implements.

You finally find your footing, awkwardly running in your heels while half hanging in the harness, your breasts under immense pain, added to by the bouncing they do because of your running. You breathing becomes more difficult both from running and from your approaching orgasm.

The woman controlling the treadmill slows it down to a walk, which is still difficult for you but a lot more manageable then running in heels with a approaching orgasm. You almost want to thank her right before you cum but she suddenly shifts it back to a running speed while you begin convulsing from your orgasm.

You pretty much instantly fall again, hanging in the torturous harness, the pain and vibrations pushing you over the edge while your ass is restlessly whipped. You hang there moaning and screaming into your gag as your breasts feel as if they are going to explode from pain.

Once you've finnaly come down slightly the blonde puts her hand on your face "good job, you came, too bad you're in the wrong place" she says in a cruell voice as the women remove your mask "we'll come collect you in a bit" they say, leaving you hanging and convulsing with a treadmill moving quickly under you.

You simply hang there crying and orgasming, losing all sense of time
