Ty always wanted more control in his life. He thought out an arousing plan. "I wish that my family would never come into this room, but that anyone else but me who walks into this room, feels an urge to strip off thier clothes, but not notice what they had done. Secondly, anyone who is in this room has to listen to my commands, but not realize what they are doing.And lastly, I wish that Linda from school would suddenly walk in this room, and be invisible to my family." As soon as he finished saying this, Linda walked in the door. Linda was a beautiful girl, with brunnette hair. She was slender, and had green eyes, and long silky brown hair. She was wearing a bikini, and was wet. Obviously, she was swimming in her backyard pool at her house, which was near Ty's. "Ty?" she said. Ty then replied, "You came here because you had something to show me, remember?" "Ah, yes, Ty. It was...um..." Ty sat back on his bed and watched Linda as she tried to remember something that never was. He made a wish in his mind. "Linda sat down and glanced at Ty. She squirmed a bit on the floor. "Well Ty, im sorry for bothering you, but i just can't remember..er, what I was supposed to er think about." she said, as her IQ got steadily lower. "Uh, well, you can like, y'know, er, do what you wanted to do and um..." she kept rambling, but her hand had unconciously slipped to her pussy, and had started to rub. She took her bikini off, and started furiously masturbating, oblivious to ty sitting on the bed. She looked to her right, grabbed a dildo that wasnt there before, and pushed it into her. She groaned, and started thrusting the dildo in and out of her vagina. Ty smiled. She kept at this for 10 minutes, getting exhausted. "Uhhnn..why..can't..I cum!" she cried. Ty made another wish. Linda suddenly bent into a ball and started to lick her own pussy. She finally came, and cum splattered across her face and body. But the cum didn't seem to stop. As she lay back in the long orgasm, cum kept spraying out of her vagina, until the floor in front of her was a small lake of cum. The cum finlly stopped, and dwindled to a small stream, which was getting slower by the second. She got on all fours, lay down in the middle of the pool of cum, and started slurping it up, suddenly feeling hungry for it. It tasted wonderful to her, and she kept on slurping while Ty contemplated. He suddenly got up, and reached for a huge black dildo laying next to him on the bed. Linda suddenly froze in an all fours position, rock-solid, and unmoving. Ty got behind her, and slowly pushed the massive dildo into her ass. The end of the dildo Ty was holding tapered off to a thin line going vertically. He pushed it in until the thine line slid in between her buttocks. He then pulled off his pants and started fucking Linda, hard. She seemed stuck to the floor like a statue. He funally came in Jennifer, stepped away. He made a wish, and his cock sprang erect again. He snapped his fingers, and Linda fell to the floor, shuddering with delight as the last few moments came to her in a second. "Get up, Linda." Ty said. Linda took an eager look at the cum, and reluctantly stood up. Linda, i control you through the dildo in your ass. You now no longer have any memory of your past, until the moment you walked into my room. I have made it so noone remembers you like you were before, but remembers you as my sister, but you are not biologically one. I wish you had the knowledge of simple math and such, and who your family is. But, you wil stay with a bimboish mind and attitude, with a subbmissive trait to me. You aslo now cannot get pregnant, or age or mature unless i wish it. And that were your mental changes for now. Now I'm going to give it a test." Ty finished. "I'm going to ask you some questions, ok, Linda?" Linda giggled. "Whatever you say, bro. But you have got to fuck me in return for this." she giggled. Test one complete. Ty thought. "Now then, what is 2+3, Linda?" "It's 5, Ty." Linmda answered. "Can we fuck now?" "Not yet." said Ty. "What is 12x12, Linda?" "It's 24, Ty." she answered. Ty grinned. Ok, the test is over. But one more thing. The dildo inside Linda started to vibrate and become warm. Linda's beatiful brown hair began to change to blond, her breasts grew a little bigger, and what was weird to her, another vagina grew between her breats, and her skin turned a light purple color. Her size decreased steadily until she was half of Ty's size. But her vaginas stayed the same size, taking up more of her body. "Now, Linda, he said. Now we can fuck." Ty said. and she hopped onto the bed and they both were soon having sex admist purple cum and sweat.
