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 till her husband says...
"Are you wearing crotch less panties?"
"Y-e-s," she answers with a seductive smile."
"Thank God for that. I thought you were sitting on the cat."
