The drive to work

Leading the way, Erika opens the front door, waving goodbye to Mom, and happily skipping to the driver-side of a blue Chrysler sedan. You are stunned for just a moment before you realize that Erika was waiting for you to unlock the car. Fumbling around in your pockets, you find the matching car key and unlock it. Erika excitedly jumps into the car and closes the door. "What are you waiting for?" you hear your mother say. You notice that her right hand is engaged with something that you can't see from in front of her. "Sorry..." you mumble, and giving your mom a peck on the cheek, you walk towards the driver's side of the car and get it.

From behind you can see your mother waving. "I've already set your GPS bro!" your sister says cheerfully. You look to your side and see your sister, with blonde hair and pigtails, in her skimpy outfit, grinning at you like an idiot. You smile back and start the engine, and slowly drive off the driveway, and start to follow the directions the GPS is giving you.

Not a minute goes by when your sister, apparently still hungry for cock, unzips your pants while you're driving and fishes out your flaccid cock. "Hmmm you still have lots of cum in those amazing balls of yours..." your sister says teasingly, and greedily starts to suck and swallow your cock. "Sis what are you doing... I'm driving..." you start to get a little bit accustomed to the new rules of the universe. Popping your now semi-erect cock out of her slutty mouth Erika says "It's not safe to drive with such pent up sperm sacks! You could see a girl on the street wanting to empty your sack and cause an accident!" and with that advice dispensed, she wasted no time and swallowed your cock again, your sister facefucking herself with your cock while you're driving.

Following the GPS is slowly leading you into the city center. Your pants are awash with your sister's drools and your own precum. At a red light, you stop and look around. Almost everywhere you look you can see public displays of all sorts of anal fucking. And every now and again you see a petite woman getting showered (Which sometimes is quite literal) with cum, who then greedily try to drink/swallow every last drop, some even going so far as to lick the pavement.

After some slow stop-and-start traffic of the city center, the GPS is finally telling you that you've arrived at your destination. You park up and tap your sister's head to tell her we've arrived. Breaking free of your cock and gasping for air she looks at you with a bit of disappointment. "Why didn't you shoot your dirty brother spunk down my whore throat?" she asked whilst pouting. The casual way in which she just said that took you by surprise for just a minute, but quickly you formulate an excuse. "Just saving it all for later... I want to really pump you full for once!" you're quite astounded at your own words, but it seemed to do the trick. Licked saliva from her lips Erika was beaming once again. "Oh great I can't wait to get doused in cum!" she said, getting out of the car.

You step out of the car and walk around to the sidewalk where Erika was already waiting. You glance at her ass, which you instinctively stop yourself from doing, before doing a double-take and realizing it was perfectly acceptable now. Walking into the courtyard of a massive office building, you let your sister walk ahead a few feet, admiring her huge purple buttplug that was on full display, despite the silver mini-skirt.
