Final Decision

I've known Cathy for more than 5 years now. We've sinc moved into our own apartment. We live and love together. We are best friends.
It was fall when Cathy and I first discussed me becoming a quadriplegic. We talked about it in great detail several times throught the winter and up into the spring months. Finally, I told her I had made my decision. I wanted to go forward with it. She agreed to help me anyway she could, so we waited for warmer weather for her parents to have the pool to be ready for summer.
We set Memorial Day weekend as the date. We were going to be at their place alone Saturday, 5/28/11. That was to be the day we'd do a trial run. Practicing her getting me out of water, or at least above it. We arrived and had lunch with her parents. They then excused themselves to go to a work function that evening. Cathy and I go into our bathing suits and headed for the pool.
Once in, we swam around and talked and waited for them to leave. As soon as they were gone, Cathy go in the shallow end with a ring on to help her float, and I sat on the side of the pool nearby. When the time was right, I just fell into the water and let myself sink, as if I were paralyzed and waited for Cathy to reach me and pull my head above water. She was right on it! Had my head up almost before I knew I was wet! We went thru the practice routine several times. Cathy had no trouble getting my head above water.
I got out and sat on the side of the pool. "Cathy", I said, "it's time". She was not so confident, and wanted to practice more, but I insisted. I said, "please Cathy, you know how much I want this". Finally, she gave in.
"Your dad has a ladder doesn't he?", I asked. She said yes, and asked me why. I explained that I wanted to be sure I had the best chance for a complete break. I wanted to dive in from the top of the ladder. Cathy was unsure, but finally agreed and told me where she thought he kept it. It was right where she said and I set it up sideways right on the edge of the pool.
There was one more thing I wanted to do before I became disabled. I knew I'd never feel anything below my injury level and that would mean sexually also. I wanted to the last thing I felt to be an orgasm. Cathy got out and helped me with that also:) There by the pool, she used her tongue, a dildo and a vibrator on me until I was about to explode. Then she said,"how's that baby?". "Fine", I said, "you get back in the pool and I'll finish this off myself". I was trembling, on the brink of an explposive and final orgasm. With my bikini slipped to the side, I worked the vibrator until I could barely walk. Then, trembling and still working it I climbed the ladder. Once on top, I balanced myself tenuously on that narrow top step. You know the one that says "NOT A STEP" lol. Anyway, I gave myself one final push with the vibrator, locking it on my clit until I felt it cumming. I turned to face the pool, my body tensed as the climax washed over me. I saw the world turn upside down, then, as I felt myself squirt, everything went black.
