you need to lick her pussy clean every time after she has been fucked.
It's very normal. My wife goes on a weekend with her bf. Comes back completely satisfied,sexually and emotionally. But she is always happy when she is back. She says because that's my nest. I then treat her like a spoiled princess. Kiss her feat, kiss her hands, take her shoes off. Make dinner for her. During all this, she start to feel spoilt and then gets naked. I kiss her body, her pussy and she gets in the mood. We then both masturbate and she tells me all details and we both cum. It's the best thing to see wife fully satisfied by a dominating man.
