Asserting dominance.

Instead of frantically looking around and trying to hide,your new alpha mind makes you stand tall and proud,your monster standing at full mast,thick, wiry veins running on it.

As usual,your baby sister runs up the stairs and throws open your door.

"Hey Dou...AAHHHH!!! WHO ARE YOU??! WHERE'S DOUG!?" She screams out in surprise.

You smile slightly,"What's the matter Sarah? You don't even recognize me now?"

"Doug? That's you?" She asks, clearly very surprised at your transformation."Bu..but ...how?"

You walk up to her and put a finger on her lips, silencing her. You wave your huge cock in her face,and she looks at it in surprise.

"It's so big!" She exclaims.

"Yes it is. Don't worry though, I'll make sure you take it without any problem." You say softly, stroking her cheek. Her eyes widen at that.

"N..no!! We can't do it!" She says, shaking her head vigorously. She tries to escape but you have her in a vice like grip.

"Why? What's the matter baby sis? You never seemed to have a problem with trying to get me near your wew-wee, why are you so jittery now?" Your face darkens and you continue,with poison dripping from your voice. "Or is it that you don't want to take a dick? You just wanted to use me as a cocksleeve didn't you?"

Sarah notices the change in your tone and shudders in your grip. Your cock twitches in between you and you roughly push her onto her knees she opens her mouth to protest and you take the opportunity to ram your monster down her gullet.

Your head hits the back of her throat. You look down at your sweet little sister. You've always loved her the most. You feel pity on her and decide you should show her some love.

"Alright,I love you Sarah and I always will. However,you need to know this is really necessary to show who is in charge here. Now,we can do this in two ways. First you co-operate and I'll take it easy on you. Second I just ram into you and break you. I really don't want to go with the second option sis so please choose carefully." Saying this,you pull out your dick from her mouth and she splutters out a lot of pre-cum,tears streak down her cheeks and she looks up at you submissively.

"I'll co-operate." She whispers. You tenderly stroke her hair at that.

"Come-on then, give your big brother the best blowie and let him fuck your sweet little throat." Sarah opens up her jaw wide and slowly starts taking your cock inch by inch. She takes in about 5 inches of it when she start gagging. You sigh and start pushing more of your length into her throat slowly. Tears start flowing down her cheeks but she doesn't complain. Finally you break into her throat, the tight muscles stretching out to accommodate your monster.

"Now, let's begin with the fun part." You grin and start thrusting. Sarah gags and pukes out precum on your dick but you don't relent. Soon your ramming with all your **** into the tiny little throat without mercy. Sarah has surprisingly stripped of her bottoms and is now stroking her 12" hard cock. Seeing this makes your balls tighten and you ram deep into her throat and unleash a torrent of cum deep inside her. You keep cumming inside her for full two minutes. Her stomach bloats up like she's pregnant and cum starts spilling out of the sides of her mouth. This triggers her orgasm too and she cums all over your legs and herself.

You pull out your cock from her mouth and she immediately pukes out inhumane amounts of your cum, gasping for breath.

You grin and grab her by the shoulders."Tell me sweetie, have you ever had anything up your pussy or ass?" You ask. Sarah meekly shakes her head in a no.

"Ah...my virgin sister." You grin again.

You make her bend down on your bed in doggy style position with her face smashed against the pillows. You slowly slide one finger along her slit. It's dripping wet.

Sarah moans loudly as you slowly lower down your face to her pussy and start licking it. Your one hand jerks her dick while the other slowly fingers her ass hole. You keep doing this unrelentingly for about 5 minutes before Sarah cum from both,her cock and pussy. You grin ferally.

"You're enjoying this aren't you Sarah?" You ask.

"Yes Doug." She moans,still riding out her orgasm.

"Won't you ask your big brother to deflower you?" You ask again,as you slide your huge cock against her folds.

"Please... please deflower me biggie." She moans again.

You slowly start inserting your dick into her pussy. Sarah yelps at the intrusion. Your cock meets a barrier,her hymen. You slowly push through it, tearing through it in one go. Sarah whimpers but doesn't say anything. You slowly keep pushing in until you reach another firm barrier. The cervix. You've managed to put in only 8 inches of your dick.

You slowly start pistoning in and out of her pussy. Sarah's pussy keeps clenching around you,as she cums again and again from your cock. Her dick too spurts out cum twice as you continue jackhammering into her pussy. Finally, you feel another load building up and you crash against her cervix to unleash another tsunami of cum deep into her.

You're so drunk on lust by now that you don't even wait and lube her ass as you pull out of her pussy and ram your length mercilessly into her ass. Sarah shrieks out loudly in pain but you don't stop. You don't bother and push deep into her until you finally bottom out, not paying heed to Sarah thrashing below you.

You start thrusting with full speed as you piston in and out of your little sister's tight,virgin ass, turning her insides into a mess. Sarah's eyes roll up into her head and tongue lolls out of her mouth as you pound your full length into her, almost tearing her into two. Your cum flows out like a burst dam from her pussy and her dick keeps spurting cum time-to time.

You feel another load build up and cum deep into her bowels,making her swell up with your huge load.

You fuck her like a rag doll in both holes for hours. Finally, after the 15th load, your dick starts going soft and you pull out and lie down on the bead. The room reeks of cum,sweat and sex. Sarah has long since passed out,all her holes overflowing with cum. She is drenched in sweat and both of your cums. Her futa dick lifelessly spurts another weak load as she lies there,well used and thoroughly fucked.

You slowly drift off too sleep too.
