On all fours (dildo in ass)

You get on all fours on the carpet and look over your shoulder toward Allen. "Take me," you say, "please, fuck me so damn hard." You remove the dildo and put in on the floor next to you. Allen stands up and, quickly removing his pants, shirt and underwear, lines himself up behind you. He pushes your panties aside and rubs the head of his magnificent pole over your lips. Your eyes close in anticipation.

Suddenly, you feel something on your asshole. You figure it's just his finger, but how can his finger be so big? He starts to push his cock into your pussy, and you put whatever's at your asshole out of your mind. He starts fucking you, slowly at first. Long, powerful, deep thrusts. You start to feel pressure on your asshole again, but you can hardly breath, let alone ask Allen what it is. Suddenly, you feel something huge enter your other hole. You look behind you and see that Allen has put the dildo in your ass while he keeps fucking you.

You're more full than you've ever been and it takes everything you have not to cum right then. You desperately want to cum when Allen does, but you don't know if you can hold out that long. "Oh gawd," you moan. "Faster. Fuck me faster." Allen smiles and playfully slaps your ass as he picks up speed.

You bring your face down to the carpet to free up your hands as your stepbrother takes your pussy and ass at the same time. One hand goes straight to your clit, rubbing to give you ever more stimulation as you're being DP'd by your sexy stepbrother's cock and the present he gave you. The other hand finds a nipple and pinches hard. You're right on that fucking edge, and want nothing more than to go over.

Allen tells you he's there, too. "Inside me!" you scream, "come inside me!" You feel him release his seed and you finally go over the edge. You cum like you've never dreamed possible. The stimulation from Allen's cock in your pussy, the dildo in your ass, your fingers on your clit, and your hand on your tit are creating wave after wave of orgasmic pleasure. Knowing your stepbrother is the one making you his property by cumming inside you just makes it more euphoric.
