I don't know when the word "duck" was called, because it has no historical value and no one will study it. What I mean by "duck" is a duck that describes a man selling sex. But sometimes I envy them. After all, they have a choice. If they are tired, they can rest. But I didn't. I'm not even as good as □, and they still have a few days to see their popularity. The customers they receive are not all energetic and sing all the way, making them gushing out. But I am different, I have to satisfy them. Pity my woman, just want me to squirt once. If you don't feel sorry for me, I will wait until they are satisfied. Once, twice or even overnight. I'm going crazy.
