You approach the side of the tank with trepidation. Here I am, a real-life mermaid, nothing short of a scientific impossibility, swimming wistfully in my confined aquarium. I had been captured in some fisherman's net and rushed to your oceanographic institute. You stare at me in the tank. Below the waist I have a six-foot long greenish fish tail, but above the waist I am like a wet dream come to life. My lovely breasts, firm and ripe, hypnotically bound slowly with my swimming. My face is gorgeous, with a mane of red curly hair, intense green eyes and lips. Well, that is the thing, isn't it? Those lips, like nothing you have ever seen on a human, full and succulent, form together in a permanent O-shape. You speculated that with leeching lips like these I must feed by sucking on my prey, most likely succulent buzzard urchins. That's what you have been feeding me every day, and right now it's feeding time. No one is in the lab this time of night but you, and you walk slowly up the ladder to the side of the tank with a long sea cucumber in your hand. You place the tip of it in the water and I slowly approach your side of the tank. My eyes look intently at the treat and my long, flat tongue extends to the tip and runs up into your heart. I slavishly run my tongue along the length of it and you feel the shiver down your spine when my tongue lightly grazes over the tips of your fingers, holding the cucumber. My tongue is surprisingly warm and yet textured, almost like a cat's tongue. After a minute or two of this tongue bath, the purpose of which you cannot smize, my hungry lips descend and engulf the lower half of my prey. You immediately feel the strength of my suction as you have to grip tightly on the other end. I then begin moving my head up and down the length of the cucumber so slowly so deliberately. You can't help but imagine what would that feel like on your own cock. Should you even dare? No one is in the lab but you. Who would know? Even though watching this incredible creature suck at this cucumber is intensely erotic, you come to your senses. No, I'm a scientist, you think? But then my eyes look up to you, intense green eyes filled with hunger, and you feel your knees buckle on the side, looking straight into your eyes as I suck and suck and suck. Your cock begins to harden and throb at the side, and it makes an obvious bulge in your shorts. I look at it. I am noticing your erection. My eyes go back to glaring directly into your own and I start sucking the cucumber with increased speed and power. I don't know what this growing tubular object is that I'm looking at beneath your clothing, but it seems like it could be something that I could sample and taste, even though it appears smaller than the usual fare. I continue to stare into your eyes as I suck and suck on the cucumber in my hand, noticing a tinge of fear in your eyes, which increases my instinct to feed. Suddenly the cucumber makes a wet series of thumps as all of its seeds and contents blow into my mouth and down my throat. The now hollow tube concaves at the vacuum produced by the suction and starts sliding deep within my mouth. Your trembling hand lets go of the cucumber and you could almost feel your heart beat thumping in your cock as you see me staring back at you, not willing to leave the side of the aquarium after my feeding. You watch my thick and translucently wide tongue start to run across the sucker o of my mouth to collect any seeds that may have landed there after the explosion. You feel weak in the knees from gazing at me doing this, because my predatory eyes are now staring at the throbbing bulge in your shorts. Perhaps if you were in your right state of mind, you would have thought before you acted, but you immediately pull down your shorts and somewhat fearfully extend your erect member to the water's edge, as if it was another cucumber for me to feed from. I look at it quizzically and look up at you with a feral glint in my emerald eyes. I extend my tongue and you immediately feel that warm, thick muscle travel under your glands and shards. You let out stuttering gasps as you grip the sides of the ladder for support, shivering in anticipation. My tongue is like a warm sponge covered in gooey honey. It slides up and down your member, producing a friction that makes your heart start beating heavily in your chest and in your chest. Each stroke of my tongue makes your cock jump and quiver and harden to an iron-like stimulus. You are shocked to discover that my tongue is covered with hundreds of tiny sticky polyps that seem to excrete a thick film over your cock. The strange fluid coats it completely and makes it feel suddenly very hot, with pinprick tingles all over, like your cock was being put to sleep, as if it were prey that could escape or swim away. You can only let out guttural mouths at the sensations of having your cock being nudged and assaulted by this alien tongue. I look up at you once more and now my eyes show the same intensity I had when I was about to feed. Before you can think or react, the watertight seal of my incredible lips contracts around half of your cock. You hear out some strange sounds like an animal caught in a trap. My mouth feels like being lost in a tight tube of heated honey. There are no teeth and no pellets, just stripped flesh and muscle constricting around your cock, causing your head to tilt back and your eyes to go back into your head for a moment. I can hear you groan out some strange words that sound pleading in the nature, like some creature being tortured slowly under a strange instrument of pain and pleasure. And then I move my head all the way to the base of your groin and then I suck. My tongue starts lapping from the base of your cock to the tip while you're fast and tight in my mouth. The strength of my tongue muscle feels like it is drawing all the blood in your cock to your glands, making it twice its normal size. You start to shake as you grip the edge of the ladder with a white knuckle intensity. And then I begin to move back and forth, back and forth, back and forth, sucking and sucking. Your cock fallen in and out of the honey tunnel that will never let it go, a tunnel that was built for one thing, sucking and feeding. At this point you can no longer think clearly, you no longer know who you are. All your existence has been narrowed down to the sensation of me milking your cock. As if hypnotized, you reflectively sway your hips back and forth in time with my slow and inexorable mouth sliding up and down your helpless shell. As my sucking becomes faster and more intense, a sense of terror starts creeping into your brain, which is almost drugged by pleasure. Will this kill you? Will your cock be ripped off and bitten? But the pleasure is so good beyond any drug or sensation ever felt by a man before. I suck and pull and tug and miff at your helpless cock and you begin to weep, weep like a baby. You're reduced to a childlike state of vulnerability and make pleading sounds, all in vain. I don't seem to register or care that I am sucking from a human being instead of a cucumber. It is irrelevant. All that matters is being fed. I suck on this appendage the same way I have sucked on thousands of other meals, with a long practiced intensity and unfailing desire for sustenance. Nothing can resist my sucking indefinitely. I know that applying enough suction and friction and movement will always yield the same result. The cucumber seeds will bloom violently into my mouth and I will swallow and suck and swallow more. You can tell that your orgasm is near, near. How you have lasted this long under this amount of sensation you have no idea, but it must be due to my process somehow. I build and build the pressure until I can extract the entire viscous load from my prey. Your hands go down to my head and frantically try to push me away, but my strength is inhumanely great. I clutch my webbed hands around your ass and thrust your cocktongue tight, heated throat. I constrict my circular muscles in my throat as it grips and milks your helpless organ with fearsome strength. Your cum shoots down my throat like white ropes blown from a cannon and I suck, suck, suck, suck, suck, suck, suck, suck. You slump against the pull ladder, panting deeply, completely exhausted. I loosen the airtight seal that my lips had over your cock and let it fall away from my mouth as I look at it curiously, seeing it wilt before my eyes. That was no sea cucumber, but the taste was salty and rich, just as I like it. I'm intrigued by this fleshy sack behind it. That is the place that seemed to house the seeds that just shot down my throat. I dart out my tongue to your balls as you shudder in fear, but you are too exhausted to move away. My tongue slides up and down your balls, sensing that there are still more seeds within. Instinctively, I glide my thick tongue up and down and up and down your balls, coating your sack with a strange fluid that is emitted from the thousands of polyps on my tongue. It feels almost loving to you, like the sensual caress of a mustard to the pet. Even though your orgasm was so powerful that it was terrifying and any rational part of you would tell you to flee, you can't help but whimper and cry little tears at the pleasure now sliding up and down your balls. It feels like floating away into heaven. You look down and are suddenly shocked to notice that your penis is slowly getting hard again. You see my eyes open wide like saucers as I notice your shaft beginning to lengthen and I increase the lapping and licking of your balls. You shake your head feebly unable to stand up and watch with horror as your cock gets harder and harder. You realize there is nothing loving about the lapping of your balls by my tongue. I am merely forcing you to get hard again against your will. You whimper now, please now, but I am unable to understand you. All I see is a sick cucumber that has not given me all of its seed. Now you are fully erect and with such speed I envelop your cock into the heated prison that is mine. You go out and I grab your eyes from the hands of you and with a strong swipe on my tail I pull you into the pool with me. You are under water for a brief moment before I bring you out so that your head and shoulders are above water and your grip onto the pool's edge so you won't go down again. My body is completely submerged, my hands clasping your ass, my lips like a vice on the base of your throbbing cock and then I begin sucking and sucking and sucking. You moan and cry like a trapped animal above me, but I cannot feel suffering. There is more seed to be sucked from you. Then suck from you I shall. What a delicious meal, what a wonderful treat you are. The pleasure burns up and down your cock and spine and forces your body into an epileptic seizure. As you thrust your pelvis animal-like into my constantly sucking hole, you no longer can see as your eyes are rolled completely back into your head. It feels as though your very life force has been sucked into my mouth. Your balls concave in the water as they are siphoned of all of the semen on food. Your body is no longer human anymore, but merely a pump of fluids shooting through your cock and into my voracious mouth. All you can do is shoot, shoot, shoot, shoot, shoot, shoot, shoot, shoot. The last thing you can feel before you slip away into total blackness is my sucking and sucking and sucking and sucking.
