When one of the two people involved in sex cums before the other, leaving the other partner quite unsatisfied.
My girlfriend always pulls a kerdunkle! We only do it when she wants to, and always cums after like 5 minutes! Its so annoying, and she makes me feel like an ass when i ask to keep going. And she wonders why i masturbate....
