44. Suspended Union

The couple is standing up face to face, the woman grips her partner's back, suspends herself, and firmly wraps her legs around the man's waist. He holds her by her buttocks and back and penetrates her. She may also lean her back against a wall for an easier hold.

Plusses
Exciting position, achievable anywhere, in all situations.

Minuses
Rather athletic position, hard to maintain unless the woman is very light.
