I wear my wife's underwear when she isn't looking.
Why do you wear your wife's underwear?
My wife doesn't look much good when she wears them, the smell of it is much better when worn by me
You shouldn't wear other people's underwear. She will think you are creepy and disgusting.
Buying my own underwear is expensive.
You should suck it up and buy you own underwear you enjoy wearing. Wearing hers is creepy and unsanitary.
