My wife and I have had a good sex life, but one night not too long ago topped all others;

  I got held over at work, a few hours of mandated overtime which, when informed about it seemed to really piss my wife off.  I came home expecting to be ranted at, but instead, as I walked in, she was there, nude, kneeling and smiling up at me.  She put her finger to her lips as to say, "shhh" and undid my pants.  My jacket dropped to the floor and I pulled off my shirt as my pants fell to the floor, exposing my already semi erect cock.  I noticed the leather cuffs on her wrists and ankles.  She reached up and grabbed my ass as her mouth enveloped me.  I moaned aloud and instinctively grabbed her hair as I began thrusting in and out of her while she moaned, gagged and slurped my swollen rod. 
  Having been surprised by the whole scene, I came hard, gagging her on a large load of cum.  She held on, deepthroating me, draining me dry, then smiled slyly at me.  Without a word she turned to crawl toward the large ottoman adjacent to our couch and only then did I notice the large black plug in her ass.  Her ass wagged at me as she moved to, then crawled up on the ottoman.  Unable to hold back, I practically killed myself getting my pants and boots off, trying to run to her at the same time.
  She had set her magic wand on the couch, as well as lube.  I sank to my knees, pulled her wrists to her ankles, causing her to fall face-first onto the cushion, her ass thrusting skyward, and attached them.  I pulled her ass cheeks apart and dove in her pussy, licking, kissing and sucking her sweet juices until my face and neck were soaked in a glistening sheen.   She had been moaning and squealing with delight, and then I had an idea.
  I ran into the kitchen, and came back with duct tape from the junk drawer.  My wife looked back quizzically and I made the "shh" motion as she had.  I took the wand, positioned it on her clit and taped it securely in place, then turned it on "high".  She jumped, crying out in surprise and delight, then moaned more, grinding into it.  This freed both my hands, causing me to grin wickedly.  I toyed with the plug, adding to her stimulation, and slid two fingers into her pussy with the other hand.  She started to pant, adding to the sounds filling the room.  I was rock hard, pre-cum dripping.
  I pulled out the plug and started licking all around her pink gape while finger fucking her, adding a third, then fourth finger.  She started cumming in waves, crying out, hyperventilating,  bucking against my hand.  I twisted my hand around while thrusting, squrting lube over the whole area, and finally, it popped past the knuckles.  She screamed out, her pussy gripping my hand, then she slowly relaxed, exhausted.
  I turned off the wand, and started moving slowly.  She groaned and sank into the cushion, drool pooling around her sweet mouth.  I gradually increased the speed of my fisting, and she came back to life, building and building until she exploded, a monumental multiple orgasm, drenching my hand.  At this point, I could take no more so I slowly withdrew my hand, stood, and thrust my raging hard cock in her ass.  I fucked her so fast and hard she was bouncing off the ottoman, and I came so hard she felt each pulse filling her.
  I stayed inside, sliding out as I withered, undid her restraints, and slid up beside her on the couch, pulling the blanket over us, and blissfully passed out.

Thanks... I will dream up some more
