A form of eating out a girl. Oral sex position.
Girl lay on their back with their legs raised up pointing toward the ceiling. The exact end position will depend on the flexibility of the receiver. This position exposes the groin area to the giving partner who kneels there to perform.
I gave my girlfriend a good seeing to by going under the hood, she was wriggling in ineffable pleasure, revealing her raw self to me, finally collapsing in cathartic paroxysm. It was the hottest moment.
