Jackie enjoyed her job as a night security guard at the Crypto and Alien Aquaria high in orbit above Jupiter's moon of Europa. It allowed her to attend her classes and still study in between her rounds through the corridors. As a dual extra terrestrial and crypto biology major, she was able to learn as she viewed the various aquatic alien creatures within their large tanks.
At times, her mind wandered towards the erotic as she thought the occasional lustful thought. It may sound strange, but it was easy to do when your time involved wandering through corridors alone with nothing but one's thoughts and the phallic shaped sea plants and alien life brought up for study to the space station aquarium. She smiled to herself as she thought of the time when she was observing the ice moon serpent from deep within the Europa moon which attached itself symbiotically to larger creatures.
The remora like creatures fed on the bits of flesh left behind when the Jovian Kraken attacked their prey. She had noticed that two of them had attached themselves to the glass of the tank, and mused at the spacing separating them. She moved her ample bosom against the glass and speculated on their relative positioning. Backing away, she had opened her blouse and undid her bra, then moved again to the glass and leaned against it. As she suspected the little lamprey like creatures were positionally spaced exactly as were her nipples when pressed against the glass.
Her mind drifted, and she imagined the sensation if the creatures were attached to her, their pulsing suction covering her large aureolas, gently stimulating them. The very thought brought her nipples to full hardness, and she allowed herself to respond to imagined sensations to the point that she found her face rubbing against the cool glass, even mouthing it provocatively. Whew! Enough of that, she thought. Time to continue her rounds before she passed the other Jovian Kraken tank and lost all control.
She had enjoyed the memory to the point that she had undone her blouse and was massaging her nipples. She had even gotten to the point where her lubrication had flowed and dampened the thong under the short skirt of her uniform. She reached under the hem to confirm. Her juices had built up and flowed down her thigh. She shook her head at how easily aroused she was, and how weak she became once it started. She knew she had to visit the ladies room soon, or she would be leaving a trail through the hallways.
