Alex smiled as he saw his young apprentice reading and he turned invisible, floating above the air. He was moving with silence, curious to see if Sarah would even notice him. If not, he would float behind her and peak at what she was reading for a bit, reading right over her left shoulder. After about a minute of this though, he turned back to normal and surprised her by covering her eyes. "Guess who," he smiled, not bothering to disguise his voice.
As Alex floated over she would look up suddenly and look around. It seemed that Sarah was not slouching, and had set up magical wards around herself to sense if anyone was about or if any magic was being used. She looked around for a little while but saw nothing, and cast a revealing spell, but it failed to overpower Alex's invisibility. Lastly she put her hand to the floor and cast a sensor spell, but since Alex was flying he avoided this as well and she went back to her studies thinking the ward had misfired. She was reading and old dark elf tome with a translation spell, it was a book on how to levitate easily and how to create powerful darkness even in the sun. When Alex covered her eyes she would stiffen but sigh when she heard his voice. "Hello Master." She said with a little smile.
"Hello, my dear," he smiled. "Interesting read you have," he added, looking at her book. "How are you ?" Alex also asked, moving one hand down to feel her soft breast, as the other gently took her hand and gently pulled on her, wanting her to stand up with him.
"Ahh, Im fine master." Sarah said with a small blush as he grabbed her breast and and hand. She stood with him as he pulled her up, already knowing where this was going.
"Yes. You are very fine," he smiled, kissing her lips as he wrapped his arms around her, feeling her butt, before moving up her body, stroking her lower back. "Sarah, would it be too much to ask for you to come with me to my room?" Alex smiled, not really giving her a choice in the matter as he kissed her neck.
"As you wish master." She said softly, holding back her soft moans of pleasure as he kissed her neck and rubbed her body. She knew that there was a large chance of this happening when she put on her slave outfit, which made her an obvious sex slave, but knew it couldnt be helped either. She would follow him up to his room if he wanted, or he could lead her up as he groped her body.
Alex suddenly picked the girl up, using his magic to make it so she was very light. He then pecked her lips again, before running to his room, holding her against his body, where she was safe. When they reached the room he placed her on the bed and began to gently take her clothes off, doing the same to himself after she was naked.
Sarah blushed as she was carried away in his arms, and then when he laid her down and began to strip her, revealing her altered body. What was once the body of a young girl was now that of a sexy woman, with large tits and ass, hour glass figure, and soft, subtle skin. She was perfect, and waiting. Also, with only a thought, Alex could make her body super sensitive to any touch, just like his brother could to any of the slaves he had owned and altered.
Alex did just that, making her body incredibly sensitive to his every touch. He inhaled and then exhaled, letting out a soft breeze onto one of her nipples, then the other. "You're beautiful, Sarah," he complimented, before blowing on her clit, then giving the nub a quick kiss and moving up to her breasts, taking one in each hand and gently squeezing and massaging them.
"Ahhh, master dont!" Sarah moaned as she felt her body heat up and become super sensitive. "Ahhh, it...its..." She moaned helplessly as he blew air over her stiff nipples, easily aroused by the simple action. She arched her back beautifully when he blew on her clit, and cried out in pleasure when he kissed it, blushing hard all the while. She moaned in pleasure as he grabbed her tits, each one warm and soft in his hands as he began to massage them, making her wiggle and moan beneath him, her pussy dampening quickly due to her heightened sensitivity.
