A sexual position where the woman is on her back and the man is vertical. The man is lifting her by the legs to raise her vagina to his penis. The term "Rising Moon" is appropriate because the woman's ass (the moon) is being lifted (the rising) off the surface she lies on.
"I want to be on my back" she said.
"I want to stay standing" I said.
So she laid back and I lifted her by the legs and entered her. "Rising moon, baby. I got a solution to everything."
