Kara whirled on Tavian. "And what was that supposed to be? Why didn't you erase her completely? You shouldn't have left any human in that drafty head of hers."

Tavian folded his arms sternly, "No way Kara. I'm not a monster. Johnny deserved what happened. But Susan? She was just an insecure girl who had never felt happiness. Look, she's gone ok? That's what you wanted isn't it?"

Kara grumbled and started looking through Susan's purse. She pulled out various forms of currency and some valuable looking jewelry. "Daddy treated her nicely." She turned to Tavian. "I'll give you your cut of the loot, but you can forget even seeing my breasts for not erasing Susan."

Kara began to walk away but Tavian smiled, "Is that so Kara?"

Kara's eyes went wide, "Please don't tell me..."

She was cut off by Tavian speaking a seemingly random phrase, "Boy oh boy it's hot." He was grinning devilishly as Kara turned around, she could still think clearly, but her body wasn't her own anymore. She turned around against her will and her hands started moving on their own.

"Tavian wait. I'm sorry I yelled." Kara pleaded as her hands gripped the bottom of her shirt and quickly pulled it over her head, her hands tossed the shirt aside, all without her will to do so. Then her hands moved to the center of her chest where her bra was clipped together. She had worn a smaller bra today and it was straining to hold her breasts down. But her mindless hands quickly removed the stress by slipping the clip loose. Her tits literally sprang out of their captivity, shaking violently at the release of tension. "Tavian, you don't have to force this out of me." She pleaded, wanting him to let her go, "I'm not ashamed to do it myself. Honest!"

But as her legs began to walk towards Tavian on their own, Tavian spoke in his soft hypnotic voice, "The best part about that code word? You're wired to not hate me for using it at my leisure. Whenever I want your breasts, I can have them. And you won't have a problem with it."

As Kara's hands grabbed Tavian's head and pulled it into her cleavage, she pleaded again, "But I do have a problem! You broke the deal! I agreed that if you would completely get rid of Susan, I would let you have your way with my breasts. But you didn't erase her, if you had, I would do this willingly!"

Tavian looked up from his fleshy home, "Yes, but you didn't want to, and I wanted you to. Don't worry, the command only makes you let me do this. If I tried anything else that you didn't want, you'd stop me." Suddenly as if on cue, Kara felt a strange pushing against her hind quarters. She looked back and saw a long cat's tail stretching from the brim of her jeans. She felt a poking at her head and touched two cat ears that had grown. Tavian smiled, "Oh, the command does that too. Don't worry, you can do that yourself at will now. Compliments to your younger brother." Kara starred in helpless shock at her younger brother who was currently suckling her nipple. She felt the pleasure pulse through her veins. It wasn't as good as what Susan could do, but it was something.

Pressure was building inside Kara from Tavian's treatment, but since her body wasn't in her control, she couldn't squirm or try to release the pressure. She moaned painfully, "Tavian...it hurts."

Tavian looked at her pleasured expression and with a quick "Oh." He snapped his fingers, releasing her hold from his hypnotic command. Kara gasped loudly and fell against the couch. She squirmed under her brother's mouth and tongue until she finally pushed him away. She focused on her ears and tail and they disappeared, just as tavian said they would.

Through panting, Kara looked at Tavian with a frightened expression. "W-what else can you make me do?" She grabbed her shirt and bra and starting putting them back on.

Tavian smiled, "I was going to let the rest of your inputted commands be surprises but, if you really want to know, I'd be happy to show you. Boy oh boy it's cold." To anyone else the phrase would've been completely out of place as it was actually quite warm. But as soon as Kara heard it, her subconscious mind took over. She lost control of her body again and her mindless hands went to work removing whatever amount of her top she had put back on.

"When did you give me these commands anyway?" Kara asked while her hands stripped of her shirt and bra.

"While I was hypnotizing Susan, you fell under my trance unintentionally. I took advantage of that and imputed several commands I felt might prove useful." Kara groaned as her body stood up from the couch and her hands pulled Tavian towards her. Then her legs did something that made her regret being conscious. Her legs began to fold themselves into a kneeling position in front of her brother. She found she was eye level with his groin.

"Tavian, you didn't...you couldn't have." Kara whimpered, hoping that her little brother hadn't given her the sick command she feared he did. Her fears were confirmed when her mindless hands reached out and undid the button and zipper of Tavian's pants. She nearly gagged as her hands worked Tavian's dick out of his boxers. "Tavian please don't make me do this." She pleaded, "I'll do anything. Just don't make suck your dick, not now." Tavian looked down at his sister's unhappy expression as she moved her head towards his dick, her mouth forcing itself open. He finally conceded just as her lips were touching his penis and snapped his fingers.

Kara gasped loudly as she regained control of her body and scrambled backwards. Tavian rolled his eyes and put away his manhood. "I'll use that one later then. It's one of my favorites. And you won't be mad at me for it!" Kara was near tears. How could her little Tavian do something like this to her? "Let's try another command, shall we? Darkness hides the truth." And suddenly Kara's mind went blank.

She came back to consciousness at the sound of fingers snapping and immediately found she bent over staring at the ground instead of sitting on it like she was. Then she realized what she was doing. She looked at herself and saw her shirt and bra were pulled up above her breasts and they were hanging down, and her pants and panties were pulled down to her knees. She could suddenly feel her body moving in a way she hadn't moved since freshman homecoming. She was grinding Tavian!

She screamed and leapt away from him, covering herself with her hands. "I have a command that makes me grind on you half naked?" She exclaimed, shocked.

Tavian laughed, "No, that's ridiculous. The command put into a hypnotic trance where you were under my complete control. Next command shall we?" Kara groaned while pulling up her pants. She was beginning to get mad. "Expose." Tavian said, which made Kara pull her pants right back down to her knees and keep her hands from covering her. "I wouldn't want to ruin anything for this next one. Which I think you'll like. I flat you are enjoying yourself." Tavian said.

Kara cocked her head, "Don't you mean "see"?" Suddenly she stopped as a strange feeling enveloped her chest. Her breasts began to shrink down until it looked as if she had never hit puberty. Her chest was now as flat as a boy's. "Why would I like this one Tavian? I don't want small breasts!"

Tavian held up a finger, "I G you are enjoying yourself." Immediately Kara's breasts began to inflate. Fat was coming from nowhere to fill out her expanding breasts, which were gaining weight and straining her back.

Kara's eyes widened, "Tavian! That's incredible! Any size?"

Tavian nodded, "I just replace the word "see" with any cup size and your breasts fill the bill. Boy oh boy it-" Tavian didn't even finish the command before his face was shoved into Kara's massive cleavage. Her shirt was already off.

"My choice this time asshole." She rubbed his face in her breasts for a moment before pulling him out and kissing him on the lips. Which shocked Tavian.

He simply murmured, "I C you are enjoying yourself." Causing Kara's breasts to shrink back to their normal size. "Good girl Kara." He said.

Kara had never had such a sudden onslaught of pleasure in her vagina. She was nearly thrown back on to the couch and frantically fought her pants down her legs. She was moaning uncontrollably from the pleasure. It felt like someone was fucking her and eating her out at the same time, within seconds she had an orgasm. Then another, and another. Orgasms kept repeating in her vagina, sending so much pleasure nerves through her she nearly popped. Her moans were uncontrollably loud. "Fuuuck!" She cried out, "This is-oooohhh!-incredible!"

Tavian clicked his fingers and Kara stopped spasming from pleasure. She was breathing heavily. "I...like that one..."

Tavian smiled, "I figured you would. See? I can do anything to you. But don't worry, you're wired to never let me have sex with you without permission. That's your choice, not mine. You're my sister after all."

Kara blushed, "Thanks Tavian." She stood up shakily, "You're my brother. That being said. I can't fall in love with you like a couple. But that doesn't mean I can't find you attractive you know." Tavian smiled knowingly, "In fact, I wouldn't mind having sex with you." She quickly pulled out his erect member, "Right. Now."

She was about to shove his cock into her throbbing vagina, when the apartment door opened. Standing there was there neighbor, Mr. States. "Kara? Tavian? I was hearing a lot of screams and-what is going on here? Don't you know why incest is wrong?" Kara stepped away from Tavian, blushing. "Just you wait until I tell your parents."

"Kara fetch!" Tavian suddenly cried. Kara didn't know what he meant until her cat features appeared and her body lunged at Mr. States. She had him in her grasp before he could even turn to run. She restrained his hands and brought him to the couch, sitting him down. "Thank you Kara. Just another command I have for you. Clothes on. Then I have some business with Mr. States." When Tavian said "clothes on" Kara quickly began putting all her clothes back on.

Tavian nodded and turned to Mr. States, who was very scared at the moment. "Mr. States, I need to calm down. Just stay calm and focus on the watch." Tavian said as he began swinging his pocket watch. ••• Thomas States woke up from his couch nap with a start. He groggily started scratching at a strange itch on his side. When he started to think about it, he didn't even remember falling asleep on the couch, but thought nothing of it. He was more concerned with the itch spreading across his body. It felt like some kind of rash.

To top it off, his shirt was beginning to feel tighter somehow. "What is going on?" He muttered, not noticing his voice was a tiny bit higher. Thomas' shirt was getting gradually tighter and tighter and the itch just kept getting worse. Finally he conceded and just stripped down to relieve the itch. His pants slipped off much easier than he remembered, but it wasn't until he pulled his shirt off and his hand touched his hair that he really realized something was up. "My hair is not that long." He said, running to a mirror.

Seeing his reflection shown a new light on was happening. His hair was extending down his back quickly, the itch was from a strange amount of body hair. Though as it thickened, Thomas realized it wasn't normal human body hair. His chest was expanding as well. Two separate bulbs were growing from his chest. He gently touched them and winced at the sensitivity.

His body was loosing it's masculine definition and even his penis was slowly shrinking into his body, replacing itself with a feminine labia. His strange new chest, things, continued to grow until they strongly resembled a medium sized pair of breasts. And the body hair covering him began to thicken until he...she was forced to classify it as "fur". Then a sharp pain greeted her head. She touched it and felt two nubs protruding from the top, and they were growing. She also noticed two ears poking from the top of her head in the mirror, they looked like they belonged to a deer.

Thomas watched her horns growing to an astounding height. She had been to the zoo before, and her horns looked just like a gazelle's. "How is this happening?" She said in horror as her feet began to pinch and clench up. They went from flesh to a hardened material and suddenly Thomas had cloven hooves. Thomas looked up from the ground at her new reflection in the mirror. She was no longer human. And as she gently stroked her breasts, she was certain she was no longer a man.

"I...What happened to me?" She asked, gripping her horns in disbelief. "How can I be a woman?" Thomas said, touching his vagina to confirm its existence, again she winced at the pleasure. "And, why a gazelle woman?"

Outside in her living room, Tavian and Kara snuck out of their hiding spots while Ms. States became distracted with her new body, and she became very distracted. They left her apartment and went back to theirs. Finally Kara spoke. "Ok Tavian, you were right. That method is a lot less, evil. Plus it's a lot more fun to watch, I am so turned on right now." She unconsciously stuck her hand down her pants.

"Plus, it pays just as well." Tavian said, holding up the stack of bills they had taken from Ms. States's wallet. He pulled Kara's arm out of her pants and handed her half of the money. She blushed.

"Well," Kara said, unbuttoning her pants, "Should we pick up where we left off?"

Tavian held up a condom and smiled, "It's your choice if you want to do this sister. You know it's serious taboo."

Kara rolled her eyes and dropped her pants and panties to the floor. "Who fucking cares?" She said as she pulled her shirt over her head. This time, by her own free will. She left her bra on as she shoved Tavian's cock into her loins. Tavian gasped at the pleasure. "Just remember, we're not a couple. We're close siblings. Got it?" Tavian kissed his sister and started thrusting into her.
