He couldn't help but gasp at the sight that greeted him as the hatch door opened. The woman he had known was changed in ways he couldn't begin to fathom. It seemed a whole different person had entered here with him only a month ago; Now gone were the sparkling hazel eyes, the short and sensible hair, the lithe body of a trainee. This creature in front of him was Aryn, but so very very different. This creature was swathed in some semblance of a dress made from thin strips of a stretchy material. The lithe body had been replaced by the curves of a far more sensual being. Plump lips drew back in a smile of greeting as she saw him, and her coal-colored hair swung down to her buttocks. Her eyes were the same color, but there was a strangeness within them. Aryn had been the sweetest, and kindest human he had ever known, but this woman had a dark glint flickering in the depths of her expression.
"What have you done?" He cried out finally, his eyes instantly went to the Mistress of this lab. Dorethea lounged against the far wall with her guard standing nearby impassively. She had not changed at all, with high cheekbones and a cruel face, she stood nearly as tall as he when she rose from her position. Her smile was full of malice and mischief when she looked upon him.
"Is something the matter Richard? I thought you would be pleased to finally see Aryn again." She strode over to where they stood in the entrance of the lab, and ran her fingers through a few strands of Aryn's hair.
"She entered your service as an apprentice to learn from you! Not be turned into some...some..." He gestured at her body, before throwing his hands up in exasperation. Aryn, his adopted sister looked back at the scientist with a cocked head, as if wordlessly questioning what she should do. It made Richard sick, this was not the sister he had left behind, she had been a head strong, intelligent individual. "What have you done Dorethea?!"
"Your sister came into my service as she showed promise to help me in all my needs and serve me well while she learned from me. She has been learning, and she has helped me in more ways than one." The older woman chuckled to herself as she walked back over to the couches and sat back down. "Aryn, why don't you make some drinks for your brother and myself?"
As his sister began to walk away he grabbed her shoulders, and she turned her large eyes up to meet his slowly as if in a dream. "Aryn, I promise, I will help you get out of this. I'll find a way to fix this." She nodded slowly, as if almost comprehending then hurried away to one of the tunnels leading off from the living area. She wore odd-looking high heeled boots that clicked on the stainless steel floor.
"Please, Richard sit. There is no reason I cannot be hospitable." Dorethea called to him, and although he hated giving into her whims he needed to find out what had been done so he could save his sister from whatever strange going-ons had happened to her.
"Madam, please just tell me what has happened to my sister. She entered your service as your apprentice to help you study the chemical effects of extraterrestrial flora and fauna. An honorable apprenticeship for us being Earth-made but I don't believe this is within the bounds of what the Company had in mind when they created the apprenticeship program." Aryn had returned with glasses filled with electric blue liquid and set it down before her brother and Dorethea before seating herself at the chair across from him. He couldn't bear looking at his strange new sister and busied himself with his glass instead.
"Richard, I don't think you quite understand the apprenticeship program. When your sister entered my service she became mine, body and soul. While you think of the more traditional methods, I used my own ideas for how she could assist me - A rare opportunity for one as herself – an Earthborn orphan. There is a reason I rarely take on apprentices. Perhaps you should ask her yourself how she enjoys her apprenticeship." Dorethea smirked and picked up her own glass, taking a long sip as she stared at Richard.
He turned his gaze away from the scientist and back onto his sister who was also demurely regarding him. "What is she saying Aryn, how did she do this to you?"
"Mistress was using me as a test subject for a type of plant that grows on Crysapthum. The plants use almost a mental connection with each other to communicate, and even reproduce. Once we were able to study how they work Mistress wanted to experiment using the same process for humans, around the same time my apprenticeship application appeared. It has been an honor to share in this groundbreaking work with my Mistress." Aryn's hazel eyes glazed over in an almost ecstatic expression as she gazed at Dorethea. Richard noticed how her body leaned towards the older woman's almost unconsciously, and how her enormous breasts made the material of her dress expand and shrink with every breath... Embarrassed he turned back to his drink draining the rest. It must have been strong for it to allow his mind to wander to such disturbing places when thinking of his adoptive sister. "I still don't understand how this explains the physical changes to my sister."
"Oh Richard, it's a bit difficult to explain to one who's career lies moreso in the field of maintenance for space vessels. How can I put this into words you would understand? All you need to know is that once I found a way to link consciousness with other sources, I also found other methods to mold one to my desires. Homo sapiens have a way of focusing on pleasure, and through both artificial and natural plant sources your sister's goal soon became to fulfill my pleasures and her own by changing her own form and mentality towards something we could both enjoy. I even developed a machine that can produce rapid physical changes in her body," At this point Dorethea pulled out something that looked like a small, silver remote. Her finger pushed an area on its smooth surface and Richard watched his sister in horror as her already oversized breasts began to swell further, stretching the material of the dress to an almost ridiculous point. Aryn gasped in pleasure and seemed to have to restrain herself from succumbing to the feeling. "As you can see, she's quite pleased to help me engage in my work and develop more ways to utilize some these compounds."
