We were halfway through a 'quiet night in' that was anything but quiet where I'd been challenged to get through all of the best woman on top sex positions in one night. I'll be honest, the Erotic Accordion below for reference had me stumped. But as a long-term sex blogger and fan of all things kinky, I'm no more going to give up in the face of a sexual challenge than a banker would turn down a bonus. I'm glad we kept at it, and I feel a bit guilty that I'd been rude about this one to begin with, because when we got the angle just right, this position gave a deep penetration and achingly hot sensation. I felt powerful, in control, and about as dominant as I get without brandishing a whip. So what of the others?
