Big Sister BJ

You drop to your knees in front of your big sister who still sat on the bed. Running your palms up her thighs and belly you grab her tits and feel their soft weight in your hands. You take in Fiona's beautiful body, still striped from the flogger's touch.

"Hands behind your back." You say.

Your sister-****, of course, obeys. Placing your hands on her knees you spread her legs and move to the space provided. Reaching around her you pull her forward, Fiona moving to your slightest direction, and bring her so she is sitting right at the edge of the bed. Her heavy tennis ball sized balls hang over the side of the mattress. Her cock lay slumped over her right leg. She was definitely sporting a chub, but it was still far from its full magnificence. Even half aroused it utterly dwarfed anything you had seen outside the family. You had been this close to her unit one other time, back during that masturbation race when she surprised you with a facial. That had happened so quickly, and you were still in your old modes of thinking, that you hadn't had a chance to admire and enjoy. You wanted more than anything now to see Fiona at her glory. Gone were your fears about whether you could handle it or not. The way your backdoor snatch was feeling right, wet and achingly hollow, now you felt like you could take a fucking fire hydrant.

"Beg me." You say.

"Please Sir. Please touch my cock. Please Master."

You wanted to play with her more, tease her a bit, but fuck that. You wanted her inside of you so bad. This would have to do.

Settling down comfortably you slowly wrap your hand around your big sister's big dick. It felt like a dick alright, just much MUCH larger. You had felt your own and you had felt Chloe's but this was a whole different level. You knew from the measurements that at thirteen and half inches Fiona was bigger than you and Chloe put together. That knowledge was simultaneously humbling and exhilarating. The number, as ridiculous as it was, couldn't do justice to actually seeing and feeling it up close like this.

You held it in the middle, a bit closer to the bottom, and there was acres of real estate both North and South of your hand. The fingers and thumb of your firm grip were nowhere close to touching. It's girth is akin to a coke can, though warm and spongy. As you shift it to the center you marvel at the sheer weight of it. If it was somehow detachable you could knock a mother fucker out with this thing! As you squeeze it you feel it swell, the steady pulse of Fiona's heart could be sensed along the serpentine purple veins.

Her long shapely legs spread a bit wider, her hour glass body arches to your touch, a hard sigh hisses from her plump ruby lips.

Goddess they called her, never had you heard a more apt title. Fiona had told you that her body brought her power in her work as a Domme. That people became her slaves once they saw the real her. You now truly appreciated those words. Had things gone differently you would have happily crawled over broken glass just to bow at her feet.

Your other hand comes up to cup her fuzzy blonde sack...it is more than a handful. Fiona takes in a sharp breath as you gently fondle and grip her sensitive lady nuts.

"Oh!" Her chest heaves upward.

"Mmmmm." You lick your lips. "Call me Jesse now."

"Yes...OH!"

All at once you dart in and plant your lips along the front part of Fiona's shaft, just above your hand. You taste skin and the soap you had used to clean your sister's body but to your lust maddened mind it was the food of the gods. You slide up and ravenously mouth Fiona's fat knob, feeling it surge closer to full erection as you do so. You suck her maw filling tip hungrily continuing to fondle her balls as you do so.

"Ohhh Jesse! Oh fuck baby, that feels so good."

"Mmmmm!"

You slurp off the end, slap it against your face, then suck it down once more. It was NOT a comfortable experience. She was just too fucking big. You feel as if the hinge of your jaw might snap as you struggle to keep your hard teeth from digging into Fiona's flesh. But you persevere and despite the struggle you love every second of it. You couldn't even take a quarter of rapidly stiffening cock, her tip so damn big it couldn't even fit far enough in to tickle your gag reflex, but you slather the section you could reach with frenzied oral delights. You suck, you suckle, you lick and slurp, and you even tongue the hole. With your shaft holding hand you accentuate what you are doing with your mouth. As you tightly wrapped lips start to bob up and down over the glans you bring your hand up slide along the slipper spit covered upper shaft.

"Mmmm! Mmmm! Mrrrmm!" You growl and hum with bestial hunger.

You twist your off hand and slip two fingers into Fiona's hot wet pussy. You plunge them in and out at the same rapid pace you were giving her head.

"Oh my fucking God! That's it baby. Holy shit, yes!"

At last you feel your big sister's titanic cock surge to its mind boggling max. It felt the the business end of a baseball bat in the tight grip of your hand. Letting go of it you now hold it in just your mouth. You suck her off like a man possessed. You were certain your sister had received many a blowjob from many a man and woman, but you were determined to show her that NOBODY could hold a candle to her brother.

"Mmmmm! MMMMM! MMMMM!!!" You vocalize.

"SSSSS Fuuuuck Jesse! Fuck you suck cock so fuckin good!" She leans her weight back, using her arms to hold herself up as she gazes down at you with those burning hazel eyes. "Suck my cock baby. Yessss!"

Her words were music to your ears. Your one hand continues to finger bang her as your other now slips down between your own legs to start to play with your own slick wet hole, a line of slimy precum from your steel hard manhood streaks up forearm along the way. Your fingers are almost sucked into your greedy and needy rear entry.

"Ohhhhh God Jesse! Yes! Yes! Mmmm!" Fiona carefully humps up into your mouth as your eyes stay locked on hers. "Yeah, lemme fuck that sweet mouth brother. Mmmmm fuck!"

Three digits in you pound your boy pussy knuckle deep. You would smile if your mouth wasn't full to bursting with hard female cock meat. If she thought your mouth was something, just wait until she feels your own Bailey gift.
