443. Dental impression

A middle-aged cocksman named Mark,
Took a sharp-tongued old bitch for a lark.
She gave him some head
And it turned his dick red
For her bite was much worse than her bark.

There's a subject I think I will broach,
Regarding a madam named Roach.
Taught her young whores to blow,
Was a great teacher, so
They referred to her as their head coach.
