sex and cats

A frustrated wife buys a pair of crotch less panties in an attempt to spice up her dead sex-life.
She puts them on, together with a short skirt and sits on the sofa opposite her husband.
At strategic moments she uncrosses her legs... enough times that her husband finally asks,
"Are you wearing crotchless panties?"

"Y-e-s," she answers with a seductive smile.

"Thank God - I thought you were sitting on the cat."

He never heard the gunshot.
