Totally At His Mercy. R-18
Hal groaned at the feel of Valerie's lips around just cock head as she sucked on it as hard as she could while reveling in his taste.
Hal reached down and placed one hand on her head while he pulled her even closer and even more onto his cock almost to the point where Valerie choked but not quiet.
In regards to fellatio, the basics were usually the same but there were two distinct approaches to the act that would only really be noted during the act.
One approach was a dominant one where the lady despite being in the 'submissive' sort of the position held the power and was in control of the situation and she could play the man like a fiddle.
The other approach was the one that was as direct as the pose itself and it was the submissive approach in which case the lady was following the lead of the man and did not have control.
