This is the Wife - I sure like your style.  A normal aspect of your screwing is your plain pleasure expression, which we all get.  I have always wondered about that, both women and men as we're in the middle or getting toward the end, why we don't smile, but have our mouths open as we have that pleasure.

My husband says I get the expression when I get right on the edge of orgasm, and stay there, and by staying there, it's actually a super-long orgasm before a climax.  I know you like to do that!
