It's been gradually building up, but I'd guess that I give my wife a facial on average 4 out of every 5 times we fuck. As long as I give her a proper pounding (at least 30 minutes and multiple orgasms) I know it's going to end with me standing over her. As I'm banging her, she'll give me a look and tell me to cum all over her, and I can feel her pussy gushing at the thought. I make sure she cums again once or thrice, before she moves to her knees to suck my cock, working for her well-earned reward. As she gets me to explode, I grab my cock and blast my jizz all over my little cumslut's face, giving her the finish she deserves. She'll usually cum one more time as she loves it when I wipe her down with many, many kleenexes.
