Spitroasted

"Good idea Sis, I will let you take Doug's ass as a late birthday present as I have allready fucked his ass" Fiona says looking up at her sister.

Before you can say anything else the two girls pick you up and bring you over to the bed as there cock's become erect as they get aroused at the thought of spitroasting you, Fiona's cock quickly reaches it's full size at sixteen inches whilst Christy's cock becomes an even bigger seventeen inches of rock hard cock at the thought of getting to fuck a boy in the ass for the first time.

You try to protest when Fiona silences you by shoving the first four inched of her cock into your mouth, at the other end Christy strokes her cock as she presses it to your tight ass hole. Unable to protest that her cock is too big for your ass because of the cock in your mouth you can only hope that Christy's cock is wet enough from your blowjob to make it not hurt as you feel her start to put pressure on the entrance to your bowls.

You wince in pain as Christy's huge cock head pops through the tight enterance to you bowls as she keeps up a steady pressure pushing in inch after inch of her cock, when Christy manages to get half of her cock in you she starts to pull out as she starts a steady rythm fucking your ass going slightly deeper on each slow thrust forward as she works to fit all seventeen inches of her cock into you.

You are focusing on the feeling coming from the ass fucking you are getting when Fiona gets bored of waiting for you to start sucking her cock so she grips your head saying "Doug if you arent going to suck my cock then I'm going to fuck your throat", as she starts to thrust her hips back and forth as she begins to fuck your mouth.

With each thrust you could feel their cock sink deeper into your throat and ass as they worked to fit the entire lenth of there huge cock's inside your body.

Finaly with a loud moan both girls managed to fit there cock's all the way to the hilt where they stoped to savour the feeling of your warm insides surrounding there cock's.

Your ass feels like its going to split open from the size of Christy's cock, but it feels so fucking good you don't care.

After they pause for a moment to let you get used to it they start to fuck you properly. Fiona drives her long cock in faster and brutal, while Christy slamming her cock into your throat as hard and fast as she can, you can feel each inch of there cock as it slides in and out of you.

Held tight between them as they fuck you hard you can feel there pre-cum flowing into you filling your stomach from both ends.

You can't help but cum as Christy's cock hammers your prostate over and over again with each thrust of her cock, soon you are cumming on every thrust Christy makes until your balls are dry and the only sign you are cumming is your cock jerking as you have no cum left.

Soon you can feel your stomach becoming full from all of the girls pre-cum as they keep fucking you with no end in sight, you feel your belly start to swell as there is no where for the large amount of pre-cum filling you to escape as you are compleatly plugged by there cock's.

The girls continue to fuck you for another ten minuets when Christy suddenly moans loudly as she stops thrusting with her cock hilted as deep as it will go as she begins to cum.

You feel a huge wave of cum shooting into your stomach as Orgasms hard, the first wave of cum makes your belly bloat so that you look more than three months pregnant.

Seeing Christy cum is enough to send Fiona over the edge into orgasm as she cum's straight down your throat with her cock stuffed into your mouth and throat to the hilt.

As both girls continue to cum you can feel your belly swelling extremely fast as it soon reaches the bed below you even though you are being held up by Fiona and Christy as they keep cumming shot after shot of thick hot cum driectly into your stomach.

It feels like it take an eternity for the girls to fininsh cumming when they slowly and reluctantly slide there softening cocks out of your mouth and ass.

Now that they stoped fucking you, you look down to see that your belly has swollen so large that you are unable to reach the bed without assistance.
