The Ulleck interviewer had been very kind to Tannera. They were a gentle race that had found in human girls a much needed substitute for their own females. Since gender integration in the work force there had been a crying need for day care workers that could deal with the Ulleck young as wet nurses.
Ulleck in normal non-nursing physiological mode could do everything for their young but nurse them. Mechanical devices could feed the young but they couldn't meet the immature's emotional need for prolonged nursing. Human females were build on a different body plan but in certain ways they were good matches for the Ulleck.
The Ullecks genitalia were located mid-torso on their front. Below that in the crotch of the females of this bipedal alien was the single mammary that actually resembled the human female genitalia. This adaption of the species from this world allowed females to remain erect and observant as the grub-like juveniles nursed them.
Their mammary were full and ripe only during the active nursing part of the reproductive cycle and outside of this time were much reduced. Nursing was only possible for the actual mothers of the young and were kept from their jobs by this prolonged duty.
Machines had been invented but using them harmed the emotional and cognitive development of the young. The act was one of great intimacy just as it was for humans. In addition, although the young lacked the morphology for speech production this was a time for intense learning and mental development as the female talked to and caressed her young. It was a job for which a young human female well suited, and could get good pay before moving into more traditional professions.
Of course not all girls were suited for the work. It required a battery of psychological tests. The high pay for the work tempted some who were not really prepared to be taken vaginally for hours at a time, day after day, for around three terran years.
In addition, their genitalia were throughly probed and examined to, first, find the best candidates. Secondly, to determine the physical tolerance for being penetrated this way. And, thirdly, to find those who not just emotionally tolerated but also enjoyed such contact.
The machine had been probing Tannera's vagina for many hours. Still slick with sweat the girl had been orgasming the whole time. The Ulleck female, !Keck, had been carefully supervising the situation but Tannera could see she was very pleased by the results. As the alien examined the physiological monitors and the girl's genitalia the two bright blue cockscomb-like structures on each side of her lower jaws had vibrated rapidly with excited approval.
The next day she came in for the final test. Before the six month training course she needed to
experience an actual nursing session. It wasn't with some newborn either but a fully grown larva
nearly ready for metamorphosis into a sub-adult. It couldn't speak but it was very intelligent with
an equivalency to a nine year old human. Like a paper person on their first route it was eager to
help and do its job well.
!Keck attended her as she undressed. The
non-sexual aspect was emphasized even if the girl was being, in a way, sexually taken. Leaning
back in her chair the girl is manually and mechanically examined a final time by the coolly
professional Ulleck. Her smooth shaved labia of her small pouting nipple-like genitalia distended
as the probe was gently forced up into her vagina. !Keck then set the mechanism to vigorously
thrust and squirm in her like the larva's nursing tube. Then she was ready.
The door opened in to the nursing chamber. It was a small round room about only two meters across. The floor was like a bowl with curved sides that was filled with pillows and one fat grub-like Ulleck.
Its skin was transparent so that its internal organs could be seen throbbing inside of it. As they stood there its large blunt head lifted and the small weak eyes focused on them. !Keck motioned Tannera to enter and then closed the door after her and went to observe on closed circuit video.
She was somewhat intimidated by it. It had been selected for this job because it was particularly aggressive at nursing and did the most did the most invasive things to its wetnurse. She was going to find out for sure if she really wanted to get into this or not. But, for today there was no turning back she was going to be here for several hours, no matter what.
Kneeling down she gently stroked the grub's head. It responded by extending it three tendrils from their sheathes, two above the eyes and one from below is mouth. She watched with fascination as she observed the forty centimeter long grasping organs slide up the canals to their openings. Fluid was being bumped into them as contractile muscles thrust them from their sheathes.
They gently entwined her hand and pulled her to it. Unresisting she lay down against the creature. Her petite form rested against its dry warm skin nested comfortably amongst the pillows, her tender nipples coning with arousal at the thought of what it was going to do to her.
Resting on her right side against its lower body she lifts her left leg exposing herself to it. The blunt head released her hand and turns to her vulnerable slit. The mouth opened and settled over her groin.
The round sucker-like mouths wetted her bare skin and once firmly sealed to her sex organs begins to suck on her. With intense interest she sees her genitals bing pulled and distended from her crotch as the powerful suction draws them three to four centimeters into its oral cavity. The action pulls her outer labia open and sucks her inner lips from in between them and even deeper into it maw.
The three tendrils extended to grip her hips to secure them for the insertion of the nursing organ. It has learned a unique method not used by all Ulleck young to secure human females. The two slippery tendrils on the top of its head slid over her hips and down in between her buttocks to her anus. Once there the tendril from the lower sheath emerged the short distance to meet them at her tight anal opening. They all begin to burrow into the her tender little rear at the same time.
Only five centimeters of the upper two can extend into her before being fully extended. Their shafts are only a centimeter or so in diameter but the lower one forces most of it forty centimeter length into her body. At its base it is almost five centimeter thick and her virgin anus spasms on the violating shaft. The tendril then coiled to form a knot buried in her rectum giving it a secure grip to drive the nursing tube into her warm moist vagina.
She lay helplessly sweating in discomfort but great arousal as well. She gently gripped the head of the grub as it eagerly took her. Thru half closed eyes she watched the fat throbbing feeding organ slide up the creature throat to her exposed and distended genitals.
With no hesitation the organ was driven into her trembling groin. As she watched thirty-five centimeters of the tube are forced deep into her hot young vaginal flesh. Its shaft varied from five to seven centimeters in diameter and had a wrinkled surface that teased her slit.
Soon she orgasmed and then again. But in time as it settled into rhythmic feeding she settled into a low state of arousal punctuated with gentle orgasm. She began to caress it slowly and talk to it as a female Ulleck would. Minutes stretched to hours but they remained in embrace locked timelessly in their mutual pleasure.
Later, when the grub had satiated its emotional needs it released her. !Keck, was very pleased as she helped the girl clean up gently licking her vagina. It was no long professional but as a loving female Ulleck who was pleased at how her grub had been attend, as it was her own young that had taken Tannera.
Tannera was pleased herself. She had gone beyond merely letting it enjoy her but had felt maternal affection for the grub as it had taken her. Maternal tenderness combined with intense sexual arousal was a potent force.
She smiled to herself. Classes began in two days, she couldn't wait.
