Ladies men love their cocks being licked straight after cumming. We can't describe the feeling, it's like cumming again feeling your velvet tongue lick our bell end is out of this world. Next time do this to your guy (even if you hate the taste of cum) guarantees another hard on soon after.
What a conundrum / dilemma us men face. This is a perfect example he/we really want to cum watching a lovely mature woman wanking your cock. But we also want to enjoy and savour the moment for as long as we can. But, she wants us to blow our load which indicates to her what a good job she's done or is doing, it's a catch 22 scenario? Or is it just me?
