This is a perfect position for a hotwife to:
1. Offer herself to be throughly fucked by a man.
2. Allow herself to be throughly licked clean by her sissy.
So, if you're a man, when you see a woman like this, your cock gets erect, ready to fuck. If you're a sissy, your mouth salivates, ready to lick.
Obviously, when I saw the picture, my mouth salivated.
