Coming Home Early

I had finished all my errands much earlier than I expected and when I got home I was happy to see that my wife had also come home early. I came in and not finding her in the living room or kitchen I figured she must be upstairs. When I opened the bedroom door I was shocked to find my beautiful wife tied spread-eagle to our bed. Her eyes widened when she saw me as I rushed to her side to rescue her.
"You're early," she whispered at me, "go away for an hour or two...hurry!"
I heard the toilet flush and realized I wasn't needed.
