Being naked beside your sleeping body somehow turns you on.

For a long moment you're torn with indecision. The thought of your former body waking up and seeing you - naked, you suddenly realize - makes you....

Dimly you realize that aside from the fear of being seen by your 'new' brother you also feel kind of turned on by the danger of the situation. God, imagine waking up to your gorgeous sister standing naked beside your bed.

The thought brings a little groan from your lips, and your hands fly up to your mouth to cover it. The body in the bed makes not a sound or twitch as you breath shallowly in an effort to make as little noise as possible.

Your nose twitches, and you realize your fingers smell. Not badly, no not badly at all. They feel wet and you tentatively lick them when you figure it out. You've got pussy juice on your fingers. Your little pussy's getting all juicy at the thought of being exposed to your brother.

I'm such a pervert, you think as you suck your fingers clean before going back for seconds. Your eyes stay fixed on the face that was once yours, and your fingers alternate between licking off pussy juice and getting more, with side trips to caress and squeeze your boobs.

You groan again, but don't bother to cover your mother, you just put another finger into your pussy alongside the first. Those fingers travel to your mouth and the other hand goes to work, trying a third finger. When that squeezes in you alternate again, trying four. That's even harder, but your pussy is so slick it's not as hard as you thought it would be and feels so damn good.

You stare at your 'brother' and wonder if you could get an entire hand in. You've seen it done on the web, but was that because the girls were naturally loose or that wet?

You pause for only a second, moaning and sucking eagerly on your slimy fingers before you make a dowel with your left hand. Your body shakes with anticipation and excitement, your breasts heave, and while you start to push your unclenched hand against your quivering pussy your other hand shifts to your breast, squeezing and crushing the sensitive orbs.

Loud moans come from your lips without the slightest hindrance. Your hand works its way in up to the knuckles before you tuck your thumb against them, pushing slowly upwards. Whimpers come from your mouth, but they're not of pain. With your thumb's first knuckle passing passing your slick lips you fold your hand into a fist.

You body rocks, undulating up and down against your hand, the fist inching deeper, millimeter by millimeter, until you feel the stretch of your lips caused by one knuckle after another until all four have entered.

Whimpers of excitement come freely from your parted lips, your eyes hooded and glazed, but fixated on the greasy head of your former body.

When the last joint of your knuckle presses against your clit as you push it deeper you clench your eyes and cry out loudly in orgasm.
