A frustrated wife buys a pair of crotchless 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 sipping a glass of wine.
At strategic moments she uncrosses her legs wide enough that her husband 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 saw the glass coming.
