It swam in a frenzy, instinctively knowing that it was about to be fed. Half a dozen assistants, and the lead researcher, Prof. Hynes, stood at the observation window, watching the creature circle in the chamber below. "And this is what we are calling a Tyrannus Temptatur, which for those with a good grounding in Latin, means 'Tyrant Feeler'," said Richard Hynes.
The assistants were new recruits at the Feltzmann Institute, and had, of course, never seen such a creature before. It was neither a squid, nor an octopus, but it had similarities to both. No-one could believe that it was native to this planet. Indeed, it had no earthly DNA. Perhaps that is what it was trying to acquire: a way to become less alien. If that was the case, then it was only interested in becoming more human, as is it did not "feed" on any other animal.
Hynes turned to the assistants, with his back to the glass. The assistants looked intermittently between him and the cephalopod below. "I have specially arranged for you to see its most fascinating behaviour. Pay close attention, for I expect you to learn much." The professor picked up a phone from the observation console, and requested that Chris meet with them.
The professor explained as many facts about the original discovery of the creature as he could until Chris arrived at the group after a few moments. He was dressed in a white dressing gown, and wore loose sandals. "This is Chris," explained Hynes. "He is also new here. He joined just a few weeks before any of you, and in fact this will be his first session feeding the creature."
"Now, this species is unique, in that it has a very peculiar diet. This particular creature feeds exclusively off of men's semen. Others of its kind obtain their sustenance from women, or a mixture of both men and women. The species needs a live subject, for reasons we have not yet been able to determine. It rejects semen given to it in a container or prosthetic penis, for example. This is where people like Chris come in. Chris, please, if you would loosen your dressing gown."
Chris did so, untying the belt and letting the robe hang loosely down his body. He was only wearing a red pair of swimming trunks underneath. "Chris, if you would kindly lower your trunks so that we can see what you're made of, please." Chris lowered his trunks to his knees.
"As you will notice, Chris has an uncommonly large pair of testicles." The professor cupped the young man's testes, and held them out so that the audience could appreciate them better. Chris watched as eyes lowered their gaze to what was hanging between his legs. His penis twitched as he sensed all eyes upon him. "We have found that the specimen seems more satisfied when the donor has a large pair of balls. The system we have at the Institute is that there is a rotation of young men who abstain from sexual activity for approximately a week. This creates an optimal build-up of semen in the testes. Beyond ten days, the body begins to break down the old sperm, as it is no longer viable for reproduction. How long has it been since you last ejaculated, Chris?"
"Six days," said Chris. His penis began to swell. He was obviously enjoying all the attention. "I had sex with my girlfriend six days ago." Some of the women in the group licked their lips imperceptibly. They thought about what sex with this handsome young man with big balls must be like.
"Good," said the professor. "Now, Chris, pull your speedos back up and make your way to the containment tank." Chris did as we was told. He now sported an unmistakable semi as he snuggled it back into in his speedos. "Feeders usually report straight to the tank rather than the observation window. I thought that, on this occasion, it would be informative if one met with you all personally. And can I just add that, if there are any young men here that would be interested in volunteering for the feeding work, then let me know. We could always use a reserve of volunteers, as the creature needs a constant supply of semen."
The professor scanned the faces of the men in the audience. His eyes locked on the youngest of them, who was also the most attractive. The young man bent himself at the waist slightly, put upon that he was viewed as prime feeding material.
There was a buzz from the console, which was a signal that Chris was at the entrance of the containment room, and ready to begin. Hynes flicked a toggle switch on a different panel, and spoke into a microphone there. "OK Chris, enter the tank." The professor's voice could be heard from speakers overhead, and from the tank, and surrounding area.
The creature froze in its tracks. Then it slowly glided towards the entranceway. Supper was about to be served.
The hatch opened. Chris stepped through, naked, and the door closed behind him. He walked slowly along a grilled gangplank. The walkway ran from the hatch to the far end of the chamber. It was two inches above the pool in which the creature floated motionlessly. Chris continued walking, and the monster submerged itself, aiming to position itself behind him.
After a few more steps, the monster lashed out with a thick tentacle, snagging Chris by his left calf. Chris froze. Suddenly, another tentacle, about twice the thickness of twine, whipped out of the water, and wrapped itself around Chris' testicles with lightning speed. His testicles were given a painful squeeze as the monster tried to drag Chris downwards by his balls. Chris grabbed a hold of his nuts, trying to maintain control.
