Wife's Purple Vibe - With a Twist

So last time, my wife Mabel treated me to something new. She strapped her purple vibe to my shaft with rubber bands and let the sensations take over. I was cumming in no time and I had no control over when it would happen. I couldn't stop it if I had wanted to. Mabel caught on to this little fact, and last night she vibed me up again but with an added twist. You may recall from a previous Mabel story that we have a papasan chair in our bedroom. The chair is basically a big bowl made of bamboo or something with a round cushion to make it comfortable. It's also adjustable; the round seat part can swivel and tilt any which way. Last night, I came to the bedroom to see the papasan chair in the middle of the floor. Mabel quietly closed and locked the door behind me. She was in panties and nothing else. "Take off your clothes and have a seat," she said. I did as I was told, and Mabel said," Arms out to the sides." She then used short lengths of rope to tie my wrists to the bamboo rail that runs around the outside of the chair frame. She knows I like to be tied up and teased. She slowly walked around behind the chair and tied another piece of rope around my throat, pinning my neck to the chair frame, as well. Not too tight, but I wasn't able to move my head. "So you liked my vibrator the other night, huh?" she asked as she began pinching my nipples. "Yes," I replied. "We'll see if you still like it after tonight." I thought Why not? Mabel strapped the vibe to my now hard cock using the rubber bands as she did last time. It lay along the length of my shaft, underneath, with the base near my balls and the head pressed to the sensitive spot under the head of my cock. She turned it on High. She came over to the side of the chair, leaned over, and began licking my nipples. I was in heaven. The buzzing sensations were once again causing my cock to swell and twitch uncontrollably. I knew it wouldn't be long, and I told Mabel so. "Good. Let's do this," she said. She moved around behind me and pushed the chair frame down towards the floor, causing the end under my legs to raise up. I was now nearly inverted. Mabel grabbed my legs behind the knees and slowly pulled towards her, careful to not slide me out of the chair altogether. I was upside down, with my twitching cock pointing at my face. She was smiling broadly now. "Surprise! Open your mouth and stick out your tongue," she said. I shook my head as best I could; the rope around my neck limiting movement. "I can't do this," I stammered, my orgasm building rapidly towards its climax. "Do it!" she said, "or no more vibe ever." I barely had time to get my mouth open before I was shooting thick streams of cum straight down at my face. I couldn't control any of it and I couldn't move or block it. I got a bunch in my mouth and down my chin. It was more cum than I'd ever had in my mouth before, and I gagged a little as some slid down my throat before I could spit. When I finished cumming, Mabel tilted the chair back up and untied me. "When we get you over your gag reflex," she said, "your cum sessions will be 100% recyclable. No more mess, no more tissues. Next time I won't need to tie you up, will I?" I shook my head no and slouched off to the bathroom to clean up.
