>>45141209Lana mommy is the easiest to break in, she's lonely and horny so she'll be down for all kinds of sexual acts. However, she'd be protective of her daughters and probably wouldn't be willing to let you do much of anything to them, she'd want you to act as a father to them.
This is where Lana gets involved, despite her young age, it's been shown that Lana is extremely thirsty for dick. Seducing her will be no issue, getting her mom on board with your actions will be. The best solution is to have your way with Lana behind her mom's back as much as possible, in no time at all she'll be utterly addicted to your cock. Then, have her initiate the idea of a threesome. Mama Lana will be more receptive to the idea if she's there to "supervise" so to speak. Over the course of several sessions, they will eventually become so depraved that they'll lust over each other regardless of your involvement.
This is when you go for the twins. With both protective figures out of the picture, you're free to groom them as much as you want. With how young and impressionable they are, it'll be easy to convince them that depraved sexual actions are actually perfectly normal. If they resist, then it's a simple matter of involving Lana and Mama who are too far gone at this point, and in fact may be happy to bring the twins in. With the combined pressure of all of their authority figures, any resistance will be crushed and they'll give in to whatever you want, they'll become easily the most loyal and obedient of your harem extremely quickly, with unmatched energy and vigor thanks to their youth.
