When someone receives a mouth full of semen and then closes their mouth and shakes their head violently like a rabid pitbull and then waits for the semen to settle in the bottom of their mouth before they swallow.
I went out with a girl and it got hot and heavy. I think she was trying to show off when she snow globed me. At least she swallowed.
In the lexicon of older women seeking younger men, a Puma is under 40 years of age, a Cougar is in her 40s, a Jaguar is in her 50's. A Snow Leopard is a woman in her 60's or 70's that has white or gray hair and likes younger men.
My girlfriend doesn't know but I'm also dating her granny who's a Snow Leopard with white hair, and unlike my girlfriend, she will let me do anything I want to her as long as she can have my young hard cock.
