*****
Katica walked down the hall to the bathroom desperate for the toilet, the door was not completely closed, but it was usually open all the way when unoccupied, and she opened the door without thinking. Just as she was opening the door she realized that the shower was going and stopped. She looked over to the shower, realizing that her father, Yanick, was in the shower. Katica was about to close the door when movement caught her eye, he was moving where she could see him and she hid to avoid his eyes. As she looked to see if she had been spotted, Katica looked between his legs drawn by what she saw, it was about five inches she guessed and it was still fairly soft. Katica had been with a few guys and knew that as soft as he was it meant that when fully erect he would probably be about eight inches, the thought made her gasp and she quickly put a hand to her mouth to stifle it.
Thinking about her dad's cock was also having an effect on her sex as she felt herself starting to get wet. Carefully closing the door she almost ran back to her room, but then she remembered why she had gone to the bathroom in the first place. After stopping in the other bathroom, Katica immediately rushed back to her room locking the door as soon as she closed the door.
The attractive twenty year old stretched on the bed, her long black hair flaring out as she did so. Swiftly removing her clothes to reveal a fit body with medium dark skin and breasts that she occasionally felt were too small, but quickly discounted that given how much attention her boyfriends had lavished upon them. Katica spread her legs, hands going right to her needy sex as she thought about her father, she had never thought about him in this way before. Katica thought about his thick but well-trimmed hair, black like hers, his dark, kind eyes, his strong nose and his full lips that she now suddenly wanted very much to taste. Her mind's eye continued down to his broad shoulders and muscled frame that she had seen on occasions when they had gone swimming.
Next lower still as she thought about his muscular stomach, maybe not quite as flat as it had once been, but still very attractive she felt. Finally she recalled how his cock had looked in the shower and though about how it would feel, especially when it was hard, and even how it might taste. At last as she began thrusting two fingers into her pussy while stroking her clit with the other hand, she imagined how it would feel to have her father's cock thrusting into her.
When she came it was hard, harder than she could ever remember cumming before and as such had to moan into a pillow to avoid being heard. As she cleaned up Katica considered, could she ever make this fantasy a reality? She spent the rest of the night considering how this might be accomplished and fell asleep wondering as she idly stroked herself.
The next morning Katica awoke, more horny than usual, by her alarm clock. She groaned looking at the clock trying to remember if she forgot to turn it off or if she had somewhere to be at this hour. As expected realization dawned, it wasn't school, but a class on hypnosis that she had been taking for months. Katica wasn't certain how interested she was in the class, she had mainly signed up because her best friend Moira didn't want to be the only girl in the class, she needn't have worried, the class was about two-thirds girls and even the teacher was a woman.
The reason she didn't quit right away was because the class wasn't cheap and it wasn't through her school, so a full refund wasn't simple. Katica suppressed the urge to curse, as she was usually loud when she cursed, and got up to shower and prepare for class. She almost played with herself in the shower, but thought better of it because she simply didn't have time. The drive was fortunately brief as she didn't have the patience to deal with being in the car and dealing with traffic. As soon as she entered the room she spotted Moira at their usual table and sat down next to her.
"Hey, Moira what's new?" Moira looked up smiling.
"Not much Katica, psychology is still a drag, but I'm managing. But what happened, no one else would notice, but it doesn't look like you had much sleep." Katica froze and could feel herself start to blush as she thought about her response.
"Well there's a guy..." She paused as Moira gave her a knowing smile. "I was thinking about him and I couldn't help myself, I was up late." Moira only smiled more, now on the verge of laughing. "But nothing's going to happen between us." Moira's smile disappeared.
"What do you mean, you're amazing Katica, any guy would be lucky to have you." Katica nodded her mood worsening as she thought about the situation.
"I'm sure he knows that, but he would never allow anything to happen between us." Moira put her hand on Katica's and attempted to make eye contact.
"Is he married?" Katica nodded. "Who is he?" Katica shook her head. "Maybe you should hypnotize him." Katica's eyes went wide at this suggestion.
"Hypnotize him, are you serious?" Moira smiled nodding.
"Why not, hypnotize him, have fun and afterwards he won't have to remember." Katica stared openmouthed as she thought of the idea. Before she could respond the teacher, Miss Collier entered the room. After class Katica sat in her room considering how she might hypnotize her dad. As she considered this she knew that she had all day, because he wouldn't be home until evening and it wasn't even noon yet. Katica wasn't feeling very confident that she could hypnotize him and wasn't sure what to do about it. Then she heard her brother, Vlad, coming into the house and a thought struck her, maybe she should practice before her dad came home. Now, excited that she had a plan she stood up and went to her brother's door and knocked.
"Yes?"
"Can I come in?" There was a short pause before he responded.
"Sure." Katica entered to find him sprawled on his bed, apparently working on homework with a furrowed brow.
"Hey, bro what's wrong?" He seemed to brighten up when she came in.
"It's calculus, I'm really struggling right now." Katica smiled and sat down on the bed.
"I have a way to help you, I can hypnotize you allowing you to focus better so that you can learn it." Vlad's eyes went wide, but his brow was noticeably less furrowed.
"Really, you mean that hypnosis class is actually good for something." Katica nodded.
"Okay, now put your books aside and lay down, get comfortable." He quickly complied putting his books on the floor and lay down in the middle of his bed. "Close your eyes and concentrate on the sound of my voice, listen and go deeper and deeper." Katica continued until she was able to hear that his breathing was smooth and even. Katica was excited, it worked, but she had to be sure that he wasn't merely asleep as she saw the bags under his eyes. "Vlad do you hear me?" He nodded. "Good, now anytime I...pat you on the head and say "good boy" you will return to this trance state, obeying my every command. Do you understand?" He responded in a monotone without moving or opening his eyes.
"Yes, Katica I understand." At first she was elated, when she heard this but then she frowned.
"From now on my pet when you are in this state you will call me mistress. Understood?"
"Yes, mistress I understand." Katica was feeling amazing, but couldn't resist one last test to determine how much control she really had.
"Alright petboy, undress completely." Vlad nodded and swiftly removed his clothes dropping them on the floor. When he returned to laying on the bed she took in his nude body, like their father although his eyes and skin were a bit lighter in color due to their mother. At last her eyes reached his groin, he wasn't hard, but she had to admit she like what she saw. "Now stroke yourself until you are fully erect, but do not cum." Vlad's hand went to his cock and started stroking it, soon he was fully erect, about seven inches, almost as big as their father. Katica hadn't planned to go any further than hypnotizing her brother, but she had been horny all morning and the sight of his erect cock was making her wet.
Katica made her decision, standing up she quickly undressed and returned to the bed. She was too horny for anything else and straddled him moving his cock to her moist entrance, she was so wet that he entered easily. Katica hesitated only a moment once he was all the way inside before she began sliding up and down, however this was not enough.
"Thrust into me petboy, fuck me hard." Vlad immediately responded by thrusting up into her, filling her and then almost emptying her before returning. Katica felt the pressure building and she pressed her hands into his chest when she came all over his cock. Her pussy lips contracted around him and he came filling her pussy. Katica lay down on top of him until her breathing returned to normal and his cock softened until it fell out of her. She turned around to grab his cock, but found that he wasn't up for another round. Disappointed Katica carefully got to her feet and was about to dress when she realized that Vlad's cum was still in her pussy, she would need to clean up before she could dress.
"Petboy, you will clean yourself and only remember what happened when you're in a trance. From now on you will study calculus carefully and when you need the information you will have no trouble remembering the information." She paused to consider if there was any other instructions that she wanted to give. "If you see any member of this family naked or having sex, regardless of who with, you will ignore them and continue with your day." Vlad nodded as Katica gathered her clothes and went to the shower. Once in the shower Katica thrust her hand between her legs, but it wasn't the same. Katica stepped from the shower frustrated, wondering if it would be worth it to check on her brother, when she heard the front door, indicating that her younger sister had come home. A thought struck her maybe practicing on her sister, Martina would better prepare her for her father. Drying herself she quickly dressed and went to her sister's room. Her knocking was swiftly responded to.
"What is it? I'm changing."
"It's Katica, can I come in?" The pause wasn't long.
"Alright." Katica entered the room to seen Marina halfway through removing her shirt.
"What?" Martina looked over as she finished removing her shirt.
