In this position, it's easier to bring her hands up the back of his thighs to grip him tightly and keep him right where she wanted him. Her fingertips dug in and held, even pulled a little as if she was trying to get closer. The position also made it easier to take all of him in, to angle her head and make the most of her opened throat. When the first taste of him hit her tongue, she whimpered in lust and anticipation.
