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.
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 f*** for that. I thought you were sitting on the cat."
