Male or Futanari ejaculation, the expulsion of semen through the shaft of a Penis. An ejaculation during Sex is often visualized through Cum Overflow.
Use the Female Ejaculation tag for female ejaculations.
Not to be confused with Precum. A good rule of thumb is that, in artwork, Precum is usually transparent, while Cum is solid white or off-white in color.
