We get Scarlet spread up against the wall, and go to work on her back side. We flog her perfect ass till it is bright red, then flog her back for the same result. A double clothespin zipper is applied from her neck to her ass.
We make her cum and as she is cumming we make her scream as we yank the zipper off her sexy flesh. The scream fills the building but it doesn't stop her from cumming, she is still cumming... What a pain slut, using the pain as a conduit for pleasure, clever girl...
Then we make things difficult, we turn her standing spread into a wrist suspension, back breaker. We professionally and thoughtfully cane her helpless feet and make the slut cum some more. Now even Scarlet is nearing the end of her endurance, but that does not stop us from ripping one more orgasm out of her exhausted body, as if she could stop us anyway...
