Do it. Fuck your little sister's face.

You move slightly back and grip your sister's jaws and her lips part easily, revealing two perfect rows of teeth and her tiny pink tongue. You love the idea of sinking your cock in between them. You've wanted to do this for so long. You look down at her vacant eyes wishing she could see what you're about to do to her, taking out the years of frustrations on her helpless body while she's completely immobile and unable to stop you. **** her smart little mouth that loves to talk shit to her older brother.

She always looked down on you, but no more. You close your eyes and sigh.

"Time to use your mouth for what it was really made for, little sister."

You push your cock into your little sister's mouth, feeling her lips part and her warm tongue glide against the underside of your cock. It feels heavenly, everything you dreamed it would be. If only you could make her experience her own humiliation and be here with you while you defile her body.

And almost as if on que, the watch on your wrist chimes again.

That gives you a wonderful idea. You take two steps back with your cock still firmly lodged in your little sister's mouth, until her body is leaning forward, held up only by your hands holding her face to your crotch. Your cock is bathed in the warmth of your sister's mouth and you fight the urge to **** it down her throat. That can wait for a moment, you have something better planned. You don't know how, but with the message that flashed past your eyes, knowledge flooded into your mind, teaching you how to manipulate the timeslip field surrounding you, that lets you move in the world frozen by the timestop watch.

The field stops just past the edges of your body at the moment, but you know that you can extend it now, and shape it around you to make time pass again for objects in your vicinity. And you have the perfect unwilling little sex-doll to practice it on. You smile to yourself gleefully as you expand the field carefully, just encompassing your little sister's head, so that she will be aware of what's happening to her, but her body still frozen firmly in place, unable to move anything from the neck up.

The response from your sister is predictable and delicious. You see it happen in real time as you sink your aching cock into her waiting mouth, piercing through the resistance at the back of her throat until you're wedged balls deep in her mouth, your nose pressed into your stomach as you fuck your cock down your little sister's gullet.

There is a moment of confusion and disorientation, for Vanessa it must have seemed like she was standing at the doorway one second, and a split second later, finding herself on her knees, with a foreign object being **** into her mouth. Then she recognizes it for what it is as the smell and taste fills her nostrils and her throat is stretched open to accommodate the invading member. Her eyes flick up to see her pervy older brother leering down at her as you violate your own little sister's mouth.

"Time for some sucky sucky, little sister. I'm going to **** your face until your ears pop."

The muffled scream that echoes from the pit of your little sister's stomach is music to your ears as you **** her face down on your cock until you're embedded hilt deep in her smart little mouth.
