The zipless fuck is absolutely pure. It is free of ulterior motives. There is no power game. The man is not "taking" and the woman is not "giving." No one is attempting to cuckold a husband or humiliate a wife. No one is trying to prove anything or get anything out of anyone. The zipless fuck is the purest thing there is. And it is rarer than the unicorn. And I have never had one.
