Best portrait lens for the pentax k 3?

For portraits on the K-3, I'd start with the Pentax HD D FA* 85mm f/1.4 ED SDM AW. It frames like 128mm on full frame, which is a flattering distance for faces, and f/1.4 gives you soft backgrounds.

If you want something shorter and easier to carry, the Pentax smc DA* 55mm f/1.4 SDM frames like 82mm and is still a very good portrait lens. For a more affordable fast option, try the Pentax smc DA 50mm f/1.8, which frames like 75mm.

Whichever you pick, the lens matters far more than the body, but light matters more still. Put your subject facing a window and expose for the face. See portraits for more on that, and lenses if you're choosing a first lens.
