Sounds like you have an awesome wife and should do something special and spontaneous in return.
Sounds like he has an awesome imagination and a blu-ray copy of Skyfall.
It was the straight razor part that gave it away to me. I shave with a straight and my wife wouldn't even think of trying to use it on me or anyone else for that matter.
Unless his wife is a barber, of course. And even then it's hard to find one who does shaves. Even more difficult to find one that uses a straight.
So, what did she want?
Seems almost too good. But if it's wrong to enjoy her treatment of you (assuming it actually happened), then I wouldn't want to be right.
