“Who’s there?” Alf demanded loudly.
A woman glided towards him between the trees. A tall woman. A very tall woman.
“Now you stop right there,” said Alf determinedly, recognising that this must be one of the aliens and waving the barrel of his rifle in her direction. His instructions dealt mostly with the likelihood of the Press or members of the public trying to get close to the aliens, and somehow everyone seemed to have forgotten to allow for the possibility that these beautiful females might decide to go where they were not supposed to be.
She slowed, but did not stop coming towards him.
“I choose you,” she said again.
“Look, Ma’am,” said Alf, lowering his rifle. “I ain’t supposed to let no-one wander about round here. You’d best get back to your spaceship right pronto before one of us gets into trouble.”
He stared at her. It was impossible not to. Her long flowing hair waved and bounced as she walked. Her body seemed to exude sexuality. Her hips were wide, yet not out of proportion. Her breasts were large, yet neither over-large nor anything other than perfectly suited to her perfect form. Her shoulders were broad and strong, but feminine and attractive. She flowed rather than moved, her tight one-piece suit showing every movement of her body. And now she was beside him.
She held out her hand to him. In a daze he took it in his.
“Come with me,” she asked softly.
“Where?”
“We must make love,” she said. “I choose you. I am a Chooser. I am ready now.”
She led him back the way she came, towards the nearest space ship. He did not resist her.
............
In a daze, Alf allowed himself to be led by the woman towards her spaceship. Only as they started up the ramp towards the open hatch did he pull back.
“I can’t,” he said, “It’s against orders. I shouldn’t be here.”
She turned towards him still holding his hand and standing only a few inches in front of him. His face was only a fraction above the level of her breasts. The pink, shiny material of her suit brushed his cheek as she turned, and he felt the soft resilience of her flesh underneath. She leaned towards him until she pressed gently against him.
“Of course you don’t have to if you don’t want to,” she said, “But if you don’t then I won’t be choosing you again, and neither will any of the others. This is your one and only opportunity.”
She turned, holding his hand more loosely and giving him every opportunity to pull away. He followed her meekly into the spacecraft.
Her cabin was uncluttered, with a bed in the very centre. There were no bedclothes on the bed, just a padded covering of a soft, black shiny material. She let go of his hand and stood next to the bed, facing him. She slowly pulled open the front of her suit until it was at waist level and the fleshy curves of her breasts were clearly visible and seemed to swell outwards as if straining for the completion of their release.
“Take your clothes off,” she said softly, standing with her hands on her hips which seemed to accentuate her figure.
He undressed.
“Come here.” She had not yet opened her suit any further, nor exposed any more of her body. He was completely naked. He went to her, and she put her hands on his shoulders, looking down at him.
“I see,” she said, “You do not find me to be a repellent alien.” Her eyes were focused on his groin. He could not find the words to reply.
“Undress me,” she asked.
His trembling fingers found the edges of already half-open suit fastened, it appeared, simply by pressing the overlapping edges together down her front and under her. He pulled, and the remaining fastening came apart easily. She shook her shoulders, and the pink suit fell round her ankles. She wore nothing beneath it. She stepped out of it.
“Are you ready?” she asked. “Are you prepared? Because you know that once we start we cannot stop until we finish.”
He did not understand the significance of her words. He nodded, and once again let her take his hand and gently pull him on top of her as she lay back on the bed.
She murmured in his ear, “Remember I am not quite the same as human women. Don’t be surprised... ”
At that moment she was, to him, exactly the same as a human woman, only more beautiful and more exciting. Her skin was warm, resilient, soft and enticing, not quite the same as human skin, stronger, more flexible. Her body was firm, yet voluptuous. Nowhere was there any fat or flab on her, and her considerably larger size than most human women only served to excite him more.
As his hardness touched her between her legs, he felt a movement from her where he touched. She sensed his surprise.
“Not the same,” she whispered, “Better.”
Her skin seemed to be swelling out from inside her, making a perfect cavity for him. Automatically be moved his hips forward and as he did he felt her flesh encircle the end of his hardness. Her skin continued to swell outwards, forming a fleshy tube encasing right up his hardness tightly, squeezing yet not uncomfortable. She put her arms round him, pulling him to her, and as she did he felt the fleshiness hesitate before stretching itself round and over his scrotum and forming a tight, strong ring completely enclosing his genitals. A slight tingling ran up and down the length of his encased member.
To his shock and concern, the whole fleshy tube then started to withdraw into her without loosening its grip on him and taking him with it. It stopped as his groin pressed hard against hers.
The tingling increased, and at the same time pulses of muscle movement started to flow through the tube holding him. The feeling was unlike anything he had ever experienced. He could not have described the sensations he felt. The warmth and the contours of her body against him, under him, were at least as exciting as the movements within that tube, yet it was the movements of the tube that drove him unbelievably quickly towards his climax.
She gasped and moaned softly, as clearly she experienced deep pleasure too.
It was only a few seconds before he exploded, gasping, into her in the most intense orgasm he had ever experienced.
“I’m sorry,” he gasped.
“Why are you sorry?” she whispered.
“For doing it so quickly. You are so exciting, so beautiful, and that.... ” He could not find words for the intensity of the physical sensations.
“It does not matter,” she said. “There is plenty of time, but you must be so careful not to over-tire yourself. I am so pleased to feel that my enzymes do work on humans too.”
“What?”
She made no reply as at that moment her eyes were closed, her breathing becoming faster and she was moaning with what was clearly intense pleasure.
He felt the muscular pulses and contractions increase as she neared her climax, and realised, shocked, that he was still hard – and totally, rigidly hard as if pushing back at the fleshy tube that squeezed at him. The tingling had increased, and there was a deep, active warmth in his testicles.
Her body bucked and writhed, taking him with her as she squirmed across the bed in the ecstasy of long-awaited orgasm. He felt a moment’s pain as the fleshy tube tightened and constricted his hardness and his testicles, but in an instant it returned to its former comfortable tightness. The muscle pulses slowed to a flutter, but did not stop.
She lay still, panting.
“Enzymes?” he demanded.
“Of course,” she said, out of breath. “My enzymes, my chemicals to keep you hard and productive. I am so pleased they are working properly on you, so the rest of this will not be a waste of time.”
“The rest?” He was suddenly, uncomfortably, aware that he was still completely trapped inside her, and that the pulsing was now increasing in speed and intensity again.
“Did you not know?” she asked. “The mating is for six days. Naturally we do not have to stay on the bed, that would be impossible, but we must stay joined.”
She saw his look of disbelief, and anticipated his next words. “I have no choice,” she told him in answer to his unasked question, “That part of me is not within my physical control. I cannot release you until the mating is over...”
