Sex On The Beach

A policeman sent his wife and child to a sea resort for a vacation. After a week he joined them in the hotel. As soon as he came to the hotel room he wanted to make love with his wife.
"No darling, we can't do it here, our kid is watching us."
"You are right, lets go to the beach."
"After a while, they start to make love on an empty beach. All of a sudden, a policeman runs into them."
"Put your cloths on immediately, shame on you, you can't do that in public."
"You are right - said the husband - but it was a moment of weakness. We didn't see each other for a week. By the way, I am a policeman too and it would be very embarrassing if you fine me."
"Don't worry, you are a colleague and it is your first time. But this is the third time I caught this bitch making love on this beach in the last week and she will have to pay for it."
