I hope you all don't mind me sharing.

Wife had me tied up on my back, partially restricting my movement. She told me "toy with yourself as best you're able", and then ignored me and read her book. She took a break from reading to use a riding crop on my exposed sensitive bits; not too hard, but it got my attention. She noticed that my penis (normally "small and soft", according to her) was actually pretty hard. She said she was considering taking advantage of that, which was incredible to hear. My penis has been inside her exactly once in the past 1342 days, and I couldn't stay hard enough to make that work for either of us. Then she ignored me some more while I played with myself. A little later, she got up without a word, took off her clothing, and sat down on my face. Exquisite! I was stroking my penis and eating her pussy, in heaven. She came pretty quickly, got up, and put her foot next to my penis. "OK, time to finish up." Which I did, trying to get it all onto her foot. She brought her foot up to my mouth and let me clean up the nasty mess I'd made. Then she untied me and told me to clean up. Miraculously, somehow there was no cum left anywhere. It all landed on her foot, and I swallowed it all!

That's, like, PERFECT sex, as far as I am concerned!
