After my wife tied me up and gunged me, I take it upon myself to clean myself up but with a twist.
I start my washing off the gunge. Then I take the tie that my wife used to bound my hand and tie it around the head of my cock, and begin tugging on it. I use the taps as a lever to get more pull on my cock.
After that I strip naked and play with myself a bit before my wife walks in on me, completely catching me off guard.
