I chose the 100-foot tank that wasn't open to the sea, simply because I didn't want any small fish swimming into my mouth. I went to the side, took a deep breath, and jumped in. I was overwhelmed by the water, briefly panicking because I couldn't see clearly, but then realized it was because I wasn't wearing a mask. The thought of drowning was a little scary; I calmed down a little as soon as I touched bottom. I blew a few bubbles, listening to the deep GLUB they made as they shot to the surface. Trying to swim along the bottom was impossible with the heavy weight belt. I knew if I let it go, I might float to the surface. I looked around and over to the viewing window in Michele's office. Even thought it was a little blurry, I could see a circular bed next to the window. Through the doorway, I saw who I beleived to be Michele at her computer. She saw me, and finished whatever she was doing before getting up. I started having tremendous difficulty holding my breath. Bubbles trickled from my nose. My body urged to inhale, and I was so horny, every little movement of my legs gave me sexual pleasure. The desire for a woman became unbearable. I looked around for the mermaids, Jane, anyone I could romp on. Then someone grabbed my hand. It was Michele. She smiled at me. The eyeshadow and dark mascara complimented those beautiful green underwater eyes. She wore a mauve sweater, short white skirt, and suntan pantyhose. We kissed. I started making out with her like I had never done before. Michele swam around me; I grabbed her leg. I couldn't take it anymore. Holding on, I pressed my lips against the bottom of her toes, opened my mouth, and inhled. Water and bubbles shot out. The urge to breathe became irresistable. I opened my mouth and took a deeeeep breath....... I rolled my eyes back a few times as I inhaled deeper. I began to spasm, inhaling and exhaling the water in and out of my burning lungs. Michele came up behind me in a seated position. From behind, she stretched her legs out alongside mine, and wrapped her arms around my waist. Her nylons were a slightly different shade than mine. I grabbed onto Michele's pantyhosed legs, while she slide her hand into the leg opening of my leotard, inside my tights, and to my crotch. With Michele's loving arms around me, I coninued to inhale until I blacked out. It was done. I don't know exactly how long I was out, but when I regained consciousness, I thought I was still drowning. There was somebody giving me CPR.....underwater. It was Janet. As I opened my eyes, she smiled at me. I was still underwater, but breathing. I panicked. I began to flail and shoot for the surface. Michele and Janet grabbed my legs and pulled me back down. "Take it easy," said Michele. "You have to get used to it. You're going to be OK. I calmed down, slowly breathing the water in and out of my lungs. I looked like an eel, my eyes were wide open, and my cheeks puffed in and out with every breath. What an experience! I discovered another new phenomenon: I could see everything clearly whileunderwater, just as if I had been wearing a mask. Michele then explained to me that part of the changes was clear vision. I was able to see clearly underwater as well as above, breathe underwater as well as above. A true amphibian! She also said that I could stay underwater indefinatley if I wanted. Your skin adapts so it doesn't become diseased from staying wet at the time. Michele explained that I was given CPR wihil still underwater. "After you drowned, I lay you down on the bottom and pushed on your chest until all the air was out of your lungs. By this time your heart had stopped. Janet was swimming nearby, so I asked her if she wanted to give you CPR. You are the first person she revived." Michele also said it was a good idea to continuously breathe water without surfacing to get my lungs used to it. I told her I had to pee really bad. She gave me a nose clip, and told me to take a deep breath, close my mouth, then hurry up and run to the nearby bathroom and go without taking a breath of air. So, time to go. My lungs are full of water as well as my bladder. Excuse me........ After using the bathroom, I jumped back into the tank and swam down to the bottom, giving the nose clip back to Michele. We then swam around the bottom for awhile, holding hands as we went. "I'm surprised to see you with your clothes on," I said. "Did you expect to see me naked?" she replied. "I didn't expect you to just walk out of your office, kick offo your shoes, and jump into the water without changing first," I explianed. Michele said "I saw you in the the tank and just wanted to be with you." We kissed, sinking down to the bottom in the process. Michele then told me about the excursions to the Caribean every year. Twice a year they travel to Cozumel, so women who want to can drown in the open sea. "How deep can you dive?" I asked her. "After you become amphibious, you can go down to a maximum of 600 feet," Michele said. "The limit is about 700, but we like to leave it at no more than 600 for safety resons. Would you like to go along on our next trip? We leave next week." "I'd love to," I said. Still not having orgasmed since becoming an amphibian, I was really horny. I slid me hand into the leghole of my leotard and touched my screaming loins through my tights. Michele grabbed my around the back of the head and kissed me passionately, moving my hand out of the way and touching me with her own hand. I returned the favor. For the next two hours my lungs fully adapted to breathing water, as we made passionate love on the bottom at 100 ft.
