An oral sex act where the woman gives a blow job to her partner, he comes in her mouth and she doesn't swallow. Then she immediately kisses and shares the cum with him. He takes it into his mouth, goes down on her and with his tongue, while eating her puts most of the cum into her and over her clit which makes it very slick. Then typically he continues to eat her until she comes herself. Might be the ultimate in crazy hot oral sex between a guy and a woman.
The first snowball kiss was so exciting that afterward we couldn't wait to do it again, but once a night is all we can manage.
