Nico did not get along with his bratty step-sister Katie. One day he was looking through a porno magazine when she arrived home abruptly and caught him unwares. The sassy, hot-pants-wearing minx immediately began to tease and mock him for what he was doing. Nico gave back as good as he got, and the step-siblings were soon arguing. Plenty of mutual name-calling ensued. Then Katie called Nico a slob, and said his step-dad was a deadbeat who had married her step-mother only because she was a wealthy widow. Nico replied that Katie and her step-mother were nothing but arrogant and shallow tramps. The step-sibling’s clash became as bad as any they’d had to date. Then Katie grew so irritated with her step-brother that she stomped off to her room. As soon as Nico was alone, he took up his porno magazine and happened to glance an unusual advert on the last page. It was for a revolutionary, mind-controlling phone app. Suddenly getting ideas about what he fun he could have using such a device on his step-sister, Nico proceeded to download it. This done, he went with his phone to Katie’s room. The busty brat was sorting through her closet when Nico entered. He made the excuse that he had come to ask her to listen to a song on his phone. Katie did not want to know. She called her step-brother a nerd and told him to get out. Instead, Nico used the app on her. The results were remarkable. In an instant, Katie’s voice trailed off, her body language turned docile, and her eyes became vacant. She had entered the deepest of trances, and was now completely at Nico’s disposal. The young man was thrilled upon seeing the extent of power he suddenly had over her. Neither was it long before he put it to immoral use. With Nico being such a horny youth, and his step-sister being so hot, it was inevitable that he would want to check her out bodily – in spite of how much he disliked her for her attitude. This began with him uttering the command to freeze – thereby causing Katie to go as still and stiff as a statue. While she was in that state, Nico removed her top and her daisy dukes, leaving her stark naked. He then spent a long time exploring her body with his hands. He fondled and squeezed her big breasts, savored the curves of her hips and butt, fingered her pussy, and finished up sucking hard on her nipples. All the while, Katie did not move. She was as vacant-minded and as subject to another’s control as a string-puppet. Later, Nico dressed her in a sexy bra and panties, and set her to cleaning up the house. When she bent over to tidy up some magazines, he froze her so that he could get a good look at her shapely butt and caress it. He repeated the process in the laundry room – where he had frozen her while she leaned over the washing machine. Afterwards, Nico made his zombie-like step-sister do the washing up in the kitchen. There, having eyed Katie’s luscious, scantily-clad body for some time, he finally decided to take things further. First came his getting her to suck his cock. Katie proved most obedient. First bending, then kneeling, she worked rigorously to please her master. There was much deep-throating and plenty of tip-to-balls licking. Indeed, Katie often lapped away like an eager puppy. Several times Nico froze her so that he could prolong a sweet sensation, and enjoy the sight of his bratty step-sister in an act of unwitting, slutty slavishness to him. In one instance of her being frozen, Nico helped himself to her mouth – fucking his cock into it just the way he wanted. This was followed by him laying Katie out on her back and fucking her in the missionary position. His step-sister gasped and moaned with pleasure as he pounded deep into her pussy. When Nico gave the freeze command, she became outwardly unresponsive. Inside, however, her nerves thrilled with pleasure. Hating her step-brother as she did, Katie would have been horrified if she had known what was happening. Not only was he taking complete advantage of her, but her body was loving it. Her pussy was soaking wet, and she was fondling herself – especially her breasts – with restless excitement. In the doggy-style fuck that followed, she panted and cooed more passionately than ever. Nico held her hair as if it were reins, and he thrust his cock right in to her sweet spot. The of it made her breasts sway and her butt shake violently. Her pussy, meanwhile, was creaming visibly. Yet Nico wasn’t finished with her yet. For as long as he had his step-sister under his control, he intended to make the most of her. Thus he got her to sit on his lap and ride him reverse-cowgirl style. As ever, Katie did as she was told. In her blank-minded but impassioned way, she worked herself furiously up and down on his cock. Once or twice, Nico froze her, letting her rest while he fucked up into her waiting pussy. After that he took her on her side. This was an exceptionally physical fuck in which the vigour of Nico’s pounding caused his step-sister’s body to shake, and her moans to fill the room. Finally, all that remained was for him to unleash his load. He did this on Katie’s face. Had she been herself, the young brat would had have never taken it in a million years. But, being her step-brother’s total slave, she gladly accepted his hot man-cream all over her cheeks and lips and into her open mouth. For Nico, the whole experience of fucking his step-sister was so pleasant that he vowed to do it again and again. As for Katie, she would carry on mocking Nico, thinking herself better than him – without ever having a clue that she became his willing, slutty fuck-toy whenever he wished it.
