Game of HE & SHE

I'm sure you can imagine,
It's simple as can be,
The place is very quiet,
The game is he and she.

She whispered, "Will it hurt?"
"Of course, a little bit."
"It's just a simple process,
Lay down and open it."

She said, "I'm rather frightened."
"I've done this before."
He started to continue,
But she interupted "It's hurting more and more."

"It's getting pretty painful,"
As the tears came to her eyes,
It was hurting something awful.
It must have been quite a 'size'.

"Calm yourself, my darling."
So she closed her dark blue eyes.
Then he said "Open slightly
So I can get inside."

Suddenly with a jump and a jerk
He gave a great big shout.
"Calm down, it's all over now."
Thank God he pulled it out.

This man is a DENTIST,
That soon you would find.
It's not what you were thinking,
It's just your dirty mind!
