A sexual position where a female lays on her back and raises her buttocks in the air allowing her legs and feet to fall toward her torso and head. A partner then proceeds to perform analingis and/or cunnilingus while buttocks and/or vagina are up in the air hence the term, Pie-In-The-Sky.
Female lays on her back and pushes their lower back and legs raised all the way up so that their ankles are either side of (and beyond) their own head while her partner eats her out.
The personeating her out can move their hands all over her body too...
When pure mathematicians dream that the elegant proofs of their π-related theorems would increase the chances of landing their names in the Mathematical Book of Life, or could propel them into mathematicalimmortality.
It’s an unspoken desire among Fields medalists—the mathematicalequivalent of Nobel Prize winners in mathematics—and first-rate mathematicians to achieve pie-in-the-sky pi dreams.
