It was the first time that Dr. Smith allowed Mark inside his laboratory. He has been working for him for 6 months already; Mark needed the extra money to go to college. He usually cleans the doctor's mansion and runs some errands for his research.
Then one day Dr. Smith asked Mark if he wants to work full time for him, double his pay.
The scientist needed Mark to stay over and help him in his experiments. Mark though "Hell Yeah! Free food and lodging."
Dr. Smith, however, warned him not to tell anyone about his experiments. Mark promised he won't.
The laboratory was under the mansion. Mark was led to the center of the room. There was a metal table, in it was a bucket-sized glass tube. Inside was a creature, the size of a basketball ball. It looked organic and fleshy; it was an embryo according to the scientist. On top of the glass tube was a cryogenic spray, it constantly ejects liquid nitrogen on the open lid to the creature. It supposed to chill the creature the doctor explains.
"This is an experiment I am working on; it needs to be fed every six hours. I bring it to the incubator for waking when it needs to eat" Dr. Smith pointed across another table.
"After 3 minutes it should start to wriggle, carefully drop the liquid on its mouth."
"The feed is in the bottles on the fridge. After feeding it, carefully scoop it up with gloves on and put it back on the glass tube. Place it back to the cryogenic chamber, clear?"
Mark nodded in understanding.
The scientist had Mark follow him on the corner of the room where the locker was. He showed him his laboratory suit, mask, and gloves. He told Mark to always wear then when working on the lab.
On the next days, Mark assisted in the routine of feeding the creature. Every time Dr. Smith would have him hold the bottled feed right above the mouth of the creature on the incubator. He was fascinated every time.
Mark noticed that the creature is actually a slug-like; it would uncurl as it gets warmed on the incubator, the flesh like skin would become exaggerated slick with oil.
Mark got intensely fascinated by the feedings, he observed that the creature's mouth was a fleshy gummy opening without any teeth only some ridges, deeper down the gaping mouth he sees tongue like textured muscles that kept on contracting as the liquid feed was vacuumed down. This view never fails to make him horny. Good thing he was wearing the bulky laboratory suit which hid the tent in his shorts.
Mark started to get these erotic ideas when he smelled the liquid feed from the bottles. He asked the scientist what it was made of but Dr. Smith never told him. Every time he held the bottle feed down, the stench would waft to his nose. The first time Mark smelled it, he immediately thought it smelled like cum.
From then on Mark started to have weird thoughts of that fleshy slug feeding on cum of his dick. He wondered how would the slippery skin feel like... The ridges and tongue muscles contracting, creating a vacuum on his cock...Oh, God! But Mark's fear of the creature and respect for the doctor kept his sanity.
Then one morning the scientist got a call, from the sounds of their conversation it was urgent. Dr. Smith later told Mark that his fellow scientist needs him to go over to Asia about a recent discovery. He already has booked a flight and will be off this afternoon.
The two went to the scientist office and gave Mark instructions of all the things that he needs to do while he's away. Especially taking care of the embryo, throughout the conversation Mark felt really nervous and thrilled.
