"No, please not"

she smiles.

"I knew that this would be your answer." she strokes your cock harder and leans forward to whisper in your ear. "but honestly: Did I ever give a fuck, what you want?"

she takes a leatherstripe and ties it around the root of your hard cock.

"Oh, is it to tight?" she askes giggling, as she sees your expression. Sur it is, but you know, that what ever you'll say now, just would just result in her tieing your cock even harder. So you consider it best to stay quiet.
"Seems your still comfortable, but no problem, I can change this." she puts on a devilish smile and ties your dick harder until you scream out from pain. She than scratches the tip of your dick with her nails and kisses you. But after that little treatment she looses the leather strip a little.
