This position requires leg lengths to match up suitably. Do remember leg lengths are adjustable for either partner by adding heels! The receiver or giver can also stand on a sturdy platform (like platforms for step aerobics).
The receiver will require something to lean against for support. They can be bent over the side of a bed, up against a wall, over a kitchen counter, or over the back of a couch. There is a definite dominant feel to this position. The receiver's cock is accessible by either, giver will need to do a reach-around.
And one more!
