Cock juice, jizzm, spunk, or simply put - cum, is the clear sign that the man has achieved an orgasm. More than that, it is also the mean of marking their territory. Much like the animals do, most men like to cum on or in their partners, kind of 'marking' them as their property. And others are just turned on by seeing a girl being covered in something that has come out of their cock, making it even kinkier than sex. Lots of girls love cum and do not hesitate to swallow it or wear it on their faces and bodies.
