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 and eventually her husband finally asks, "Are you wearing crotch-less panties?"
"Y-e-s," she answers with a seductive smile..
"Thank goodness..... I thought you were sitting on the cat."
