Your own sisters

Both of your hot sisters are among the first girls you've lusted after in your teenages years. Sure, you've always felt guilt for those uncontrollable urges, and more than one wanking session ended with you calling yourself a sick turd. But it never prevented you from doing it again, sometimes in their underwears. Not only are they incredibly sexy and the sweetest girls you could ever dream of having in your life, but the taboo of **** has always been among your secret kinks.

Now, as God incarnate, you can choose what is or isn't taboo. You're not bound to morality anymore, you decide what is right and what is wrong and can even impose rules for humans while placing yourself above them. You still feel a tiny hint of doubt and guilt about those impious desires, but you simply wish them away. And, just like that, you're free from your last fetters.

Your decision is taken. They will be yours, body and mind, and they will love every minute of it.

A quiet smile on your face, you get out of your bedroom and stealthily go downstairs, using your new powers to muffle the sound of your steps. You find the girls in the living room, lying reversely on the couch, polishing each other's toes while absentmindedly watching a show on TV. You don't even bother to identify it, but you make sure they both focus on everything but you while you check them.

Lara is the older one. She's a gorgeous blond girl with blue eyes, full lips and harmonious facial features. She's always been very protective toward you and your little sister, Maya, but she also takes care of herself. She's fit and always has the perfect hair style, the perfect makeup, the perfect clothing, to put herself in her adventage without looking like she's putting too much effort into it. She exercises a lot, is careful about what she eats, take her law studies quite seriously and always engage cautiously into her relationships -although she's single right now since her last boyfriend and her decided by mutual agreement that they had no time for each other anymore. Despite all that, she's a wonderful big sister, always supportive and ready to have fun with her siblings. But what interests you right now is her body. She's taller than most of the girls you know -she was actually the same size as you before you used your powers to give yourself a sudden surge of growth- and has long legs you've dreamed for a long time to wrap around your waist. Despite her thin waist, she has big round tits she often complain about because they embarrass her when she's exercising at the gym and sometimes cause her pain in the back.

Maya is her opposite in many ways, but her carbon copy in other. She's far shorter, but also better gifted by nature. She has wider hips and an ever huger rack, which isn't surprising since she's lazier and a bit chubby. She's also paler, compared to her athletic sister whose tan come from regular sessions of jogging and swimming. Other than that, she has the same eyes and facial features in a slightly smoothier model. She would also have the same hair if she didn't died herself red these days. She's more careless, which she can afford to be with both her big brother and big sister looking after her, and she's funnier and livelier at the same time. She's always been the party-goer and the clown of the family. But she's also a disaster when it comes to relationship. She can't stay single for more than a couple days and more often than not find herself dating bad boys who leave her in a wreck state, after which it's always up to Lara and you to spoon-feed her with icecream until she's back as your joyful baby doll of a sister. She's about to reach the end of her last year of highschool and can't make her mind up about what she wants to do later.

You think about it for a few seconds, then use your powers to alter their bodies without them noticing. First, you make their chests firmer, rounder and even bigger than before, but toy with the laws of physics so they won't weigh anything on them. You remove Lara's tan marks and make Maya's hair naturally red. You also remove all hair below their neck and make sure it can't grow back, except for a triangle of pubic hair which will always stay naturally trimmed. Then, you make their bond to you unfailing. Their bodies will shiver with a touch of your dick, your cum will act as a hard **** on them and your presence alone will bring them happiness. But most of all, you make them both immortal in the same way as you. They cannot age, nor can they get sick or hurt.

Once your satisfied with what you've done, you make your clothes disappear and let them notice your presence, while you stand with your fists on your hips and your erect dick pointing to the ceiling.
