rooms hote too expensive

A couple of young people visit a Sexologist.

Young man: "Doctor, we are married new wife. We want to know if our way of having sex is right or not. Will you see him? "

Sexologist: (Kind of surprised for a moment, but then agree).

The two young men then climbed into bed and have sex. Once they are done,

Sexologist: "Yes, your way is right. It costs Rp. 25,000. "

After paying, both then go home. But the next day they reappear to the Sexologist. This time they both have sex in different positions. And so on for 4 days in a row they go back and always have sex with different styles and positions.

(On the fifth day, the Sexologist can not take it anymore).

Sexologist: "I see that your way is right and you are already an expert in sex. Why do you always come back again? "

Young man: "Hotel room is too expensive. While here only Rp 50,000. Besides, the cost to the doctor will be changed by my office. "
