Dirtiest whore competition

You watch Jennifer work her tongue along your floor, methodically licking her way towards the motherload beside your bed. You lightly help Melissa move up and down your cock with one hand and a light thrust as you finish the last of the energy drink.

"Alright!" You say, crushing the can in your hand and forcing yourself down Melissa's throat in the same motion. She gags slightly, but looks up at you trying to smile, hoping you've somehow already processed the drink. Jennifer sits up on her knees beside your bed quickly and turns to face you, her face and body now soaked in piss. Her huge tits bounce and glisten; only one heart shaped pastie left, the uncovered pink nipple standing out proudly in the center of her firm breast.

"Dirtiest whore contest!" You exclaim, removing your cock from Melissa's throat and stepping over towards a whiteboard on your wall. On it you write "Jennifer" and "Melandra" then underline them. "Winner gets my load!"

The sisters glare daggers at each other while you try to tally a current score. You mark one for Jennifer for her progress on your floor and another for her piss soaked body. You mark one for Melissa gagging on your cock moments ago.

"My name's not Melandra...." Melissa starts, looking at the score and immediately thinking better of it. "It's... uh... Cumdumpster!"

You erase "Melandra" and replace it with "Cumdumpster" along with another mark for the effort.

"And... and... don't forget I was licking your piss on the ground outside!"

Your sister did the same thing outside, you think, she's lucky you aren't marking down the titfuck to make it more interesting. You look into your bedroom at Jennifer, who now has her face pressed firmly into the puddle by your bed, hair and all, tongue out as she rubs her entire head back and forth to lick. You mark one in her column.

Melissa looks at the board and starts to panic. She quickly turns around and bends over, showing you the glittering jewel in her asshole for the first time. You hadn't noticed the butt plug. Nice. Score one Cumdumpster. You adjust the score accordingly.

She begins working it in and out of her asshole with one hand as she half crawls towards the remaining drag trail, running her tongue on the dry floor the entire way. She finally reaches a missed spot and begins to clean it while working the plug faster. You mark another for her. The score is now 3-4, advantage Cumdumpster.

Jennifer notices the deficit as she begins to run out of piss to lap up. She immediately begins to look about for other ways to earn points. She stands up and starts pulling off her tiny panties as she jogs towards you. You watch the way this complex series of moves tosses her huge tits around in a satisfying manner; bouncing and jiggling their way towards you. You almost want to reward how turned on it makes you feel with another point but decline, as Jennifer turns around and bends over for you.

She sticks two finger from each hand up her ass and quickly begins fighting her own tight asshole to gape for you. Her fingers spread further as you are able to see a black void forming between them. Now fairly buzzed with piss, Jennifer moans at her own ****. Great show. You mark a point.

You begin slowly stuffing your cock in her ass, sliding in smoothly between her fingers with her help, still lubed up with the sister's spit. You begin to thrust as you mark another point.

5-4 Jennifer.

Melissa quickly gets up rips the shirt off her nipples with a snap, tearing it off and tossing it behind her in the same motion. Her breasts bounce with freedom briefly and she ducks to get under her sister, who fights back slightly to keep her away. Melissa gets the upperhand since Jennifer's fingers are still around your cock deep in her ass. She tosses her head underneath your balls with gusto, immediately beginning to juggle them on her tongue as you work in and out of her sister's ass.

You award one point for the balls and wonder if you should count the nipple rip or winning the fight. Nah. Tie game.

"OooOOooh boy! I just love eating my sisters pussy!" Jennifer exclaims with pornstar quality fakeness. She proceeds to pull her hands out of her ass, allowing it to reform more comfortably around you, then spreads her sister's legs and starts going to town as noisily as possible. She laps wildly, more for show than effect, and starts moaning loudly with a sexy voice. You mark a point for effort and the incestual cunnilingus.

Not to be outdone, Melissa starts stuffing your balls in her mouth, then sticks out her tongue as far as possible to work the underside of your dick as you plow her sister's ass. You mark one for Cumdumpster, evening up the score once again.

This might be the best idea you've ever had. You wonder how they plan on topping themselves as you increase the pace of your anal ****, relishing the feel of Melissa's efforts.
