I approached the side of the tank with trepidation. Here she was, a real live mermaid, nothing short of a scientific impossibility, swimming wistfully in her confined aquarium. She had been captured in some fisherman's net and rushed to our oceanographic institute.
I stared at her in the tank, below the waist she had a six-foot long greenish fish tail, but above the waist, my God, she was a wet-dream come to life. Her breasts were the size of melons, firm and ripe as they hypnotically bounced slowly with her swimming. Her face was gorgeous, with a mane of red, curly hair, intense green eyes, and lips, well that was the thing, wasn't it?
Her lips completely covered the lower part of her face from her chin to her nose, two fat and succulent sausages that formed together in a permanent "O" shape. We speculated that with remora lips like those, she must feed by sucking at her prey, most likely sea cucumbers and urchins. That's what we had been feeding her every day, and right now, it was feeding time.
No one was in the lab at this time of night but me, and I walked slowly up the ladder to the side of the tank with a long sea cucumber in my hand. I placed the tip of the cucumber in the water and she slowly approached my side of the tank. Her eyes looked intently at the cucumber, and her long, flat tongue extended to the tip and ran up and over it. She slavishly ran her tongue along the length of it and I felt a shiver down my spine when her tongue lightly grazed over the tips of my fingers holding the cucumber. Her tongue was surprisingly warm and yet textured almost like a cat's tongue.
After a minute or two of this tongue bath, the purpose of which we could not surmise, her monstrous lips descended and engulfed the lower half of the cucumber. I immediately felt the strength of her suction as I had to grip tightly on the other end or else the cucumber would fly right out of my hand. She then begin moving her head up and down the length of the cucumber, so slowly, so deliberately. I couldn't help but imagine what would that feel like? Should I even dare? No one was in the lab but me... who would know?
Even though watching this incredible creature suck on this cucumber was intensely erotic, I came to my senses; no, I'm a scientist, I thought. But then her eyes looked up at me, intense green eyes filled with hunger and I felt my knees buckle at the sight of her looking straight into my eyes as she sucked and sucked and sucked. My cock began to harden and throb at this sight and they made an obvious bulge in my shorts. She looked at it! She was noticing my erection! Her eyes went back to glaring directly into my own and she sucked the cucumber with increased speed and power. Suddenly the cucumber made a wet series of thumps as all of its seeds and contents blew into her mouth and down her throat. The now hollow tube concaved at the vacuum produced by her mouth and started sliding deep within her.
