Ngocong sambil diikat

I get punished for being talking back - my ankles and wrists are cuffed together, I'm stripped and left with nothing except my vibrator. I'll only be united when I cum, but..... I have to edge. I can't cum cum until my pussy is throbbing, aching and can't take it anymore. I get so close so many times, my pussy throbbing and clenching each time the vibrations run through my clit. I slowly swell up, desperate to cum but deny myself the luxury like a good girl. Its not long before I can't take it anymore and clench so fucking hard as I cum, straining in the cuffs and hoping I've done gone enough to be let out.
