Why not have some fun while I have this... thing Justin thought to himself and pointed the device at Maria:"You will enjoy my penis and you can't think of anything else." At first she stared at him confused, then she emitted a white, glowing halo. The surprising thing was when her clothes vanished, but Justin figured that will come in handy soon. Also her expression became a lot more... dim. A few seconds later the glow vanished again, and immediately Maria in all her naked glory took a few steps forward and begun caressing Justin's dick with so much decication like nothing else mattered to her anymore. Justin decided to sit down, and in that position the head of his cock reached slightly above his eyes. Amused he watched how Maria kept pumping, kissing, stroking and licking his shaft. She also brought in her B-cups, which felt nice, but didn't do much in terms of getting him off. Feeling his arousal grow he kept enjoying the show and the sight of his completely naked sister, and slowly allowed himself to get closer to an orgasm. It took her a few more minutes till he was so close that he couldn't hold it much longer, but before he could ask her to swallow, she already had her lips wrapped around the head of his cock, at least as much as she managed to take in. Justin let himself go and started shooting his load right into his sister's mouth. She swallowed as fast as he could launch it, and did not let a single drop go wasted, while she kept pumping his shaft to squeeze out the last drip of cum.
When Justin drifted back to reality, Maria was still working his shaft. An orgasm with a dick this size felt different, powerful, almost overwhelming, yet afterwards he was a lot more exhausted then he was used to. And much to his surprise his dick didn't really seem to go down much, but considering the size his body could hardly store all that blood, and even if it could, it might take several minutes for his body to pump it out. The other thing that surprised him was that his sister was still handling his dick exactly like before he came.
"You're doing a good job." Justin told her with a smile, but there was no reaction whatsoever on her face. "If you want you can stop now." he offered, but again she didn't even seem to hear him. Curious he waved his hand in front of her eyes, and while she clearly seemed to see it, all she did was to evade it to keep her eyes on his dick. But before he could figure out what was going on, his door suddenly opened and his mother stood there with two plates of food in her hand.
"Dinner is ready!" she chirped, and beside a quick look she didn't really seem to care that Justin was sitting there with a boner, and Maria was treating it. The device must have change her as well. Justin figured, but why that made her bring up dinner was beyond him. Feeling slightly awkward he watched how she put both plates on his desk, then once again looked at his shaft and then at his sister, then back to him.
"Don't forget to feed her this time!" she commanded him.
"Why... would I feed her?!" Justin asked confused.
"Are you joking me again young man?" her mother seemed to get a bit angry "You know she can't do anything by herself, except for... well you know." she pointed at his dick. Both watched for a moment how Maria once again tried to use her tits to service his cock. "Well then, see you later." his mother excused herself and left, closing the door behind her. Justin grabbed his plate and started eating, while Maria still mindlessly worked on his cock. It took him a while to figure out that he had told her that she can't think of anything else and the device seemed to have taken that quiet literally.
"Damn I wonder what's going on in your brain." Justin said after he had finished his meal. As instructed he tried to feed her, while she didn't even stop a second on his cock. It was difficult but possible, as she swallowed basically everything that entered her mouth. In between feeding her he experimentally put his finger into her mouth, and she immediately started sucking on it until he pulled it out again. "Damn I turned you into a cock-slut by accident." Justin laughed, of course Maria did not react to it. Curiously he reached out for the Reality Bender again, fired it at Maria's tits and said: "Firm G-cup tits." Immediately her boobs were surrounded by that white glow again and started expanding. Once again just a few seconds later the glow vanished and left her with unnaturally firm G-cup tits, that now wobbled like jelly with every of her moves. Encouraged by his success he fired the device at his dick again and said "Ten inch boner". A bit of glowing later his dick had shrunken down to exactly ten inches, yet stayed hard as rock for some reason. "Right... I said boner." Justin slapped his forehead. But before he could correct his mistake Maria suddenly moved into his lap and took his cock into her watering pussy. Distracted by that sudden pussy around his cock and those huge and firm tits jumping in front of his eyes while his sister moved up and down on his shaft, he put the device aside again and decided to fondle and kiss those tits instead. Undoing his boner just didn't feel right at this time, and he could still fix that anytime later, after he was done enjoying those melons and being fucked by his mindless sister.
