Unleash the Beast!

Ten seconds go by. Then twenty. Then thirty.

You hear your sister let out a breathy snort.

You honestly weren't sure what was happening right now. Everything had gone still. Very slowly you rise from prostrate and back to a kneeling position. You look up thinking you were about to see your big sister. As your eyes meet hers you are shook to the core. What you saw leering back was only partially the Fiona you knew. Her wide eyes were windows into a raging inferno. Her teeth were bared and clenched like a hungry wolf protecting a fresh kill. Her face twitched, her jaw clenched, her muscles sporadically flex and jump, and her fists clench and unclench in place. Perhaps most intimidating of all was that her cock was rock hard! Seeing over 13 perfectly rigid inches of thick dick looming just a foot from your face was like witnessing a UFO. It was an impossibility and yet there it was.

You watched as your sister struggled. The monster had come. At long last Fiona's monster was here. She had held it back for as long as she could but having you here like this...it was too much for her.

For a moment you are frightened, but only for a moment. You knew this was coming. You remember Fiona small and scared, crying, admitting to you that she hated herself because of this monster. For such a dominant personality she loathed the loss of control. You remember later Fiona confessing that she needed the beast inside of her, that it gave her strength and confidence. This fearsome creature towering over you was the white hot fire that burned inside Fiona's soul.

Fiona takes in a long hissing breath through her teeth and you watch her struggle to reign in the demon. "Jesse...g-get out!"

It killed you to disobey her but you would not let her off this easy. You loved this woman with all your heart and soul. She had conquered your heart but she had not yet conquered her own. You would help her with that...even if it killed you. Your mind working at the speed of light you run over what you knew. Once, exactly and only once, Fiona had completely lost control. And that was years ago. You had faith in her. You trusted her. And if she hurt you...you would forgive her and help her forgive herself.

Besides...

...

...you kind of...

...

...really...

...

...wanted this.

The rushing rapids of your lust swept you along every bit as much as your love. You wanted the monster! Fiona said she would be gentle with you. She had been lying. Not on purpose, but there was nothing gentle in the expression and body language of this hellcat. That was okay by you. You didn't want gentle right now. You wanted hard fucking, raw animal breeding, and it looked like Fiona was game. You were such a lucky boy.

"G-get out!" Fiona struggles to say again.

You straighten up your back and stare her right in the eyes. "No!"

Her eyes widen and her nose flares as she snorts like an enraged bull. "WHAT!?"

You tremble but hold your position. "No! I will never run from you! I'm not scared of you! I love you! Use me. Use my body. I won't fight you. I want it!" You fill your lungs, grip your knees and gather your courage then add. "You're gonna breed your boy! Right now! I've been a good boy and I deserve..."

WHUMP!

Before you even knew what was happening she had you by the hair and had spun you back to pin your head against the wall. You let out a gasp of surprise. As you get a taste of your sister's speed and power it hits you with absolute clarity, if the safe word doesn't work there isn't a god damn thing you could do to stop her. That knowledge is fuel for your twisted soul. You dick gets harder and your pussy gets wetter.

You open your mouth to speak only to have it filled with Fiona's record breaking schlong. Your jaw damn near dislocates as she zips right through your mouth to slam into the back of your throat! You spasm and make a deep glugging noise as your Mistress powers right past your gag reflex to stretch your unprepared throat.

"GLLMMMPPPP!!!"

Your body didn't know how to respond! You shake and quiver and gag yet not gag. She was only halfway in and by the crazed look in her eye she was going for more. Your hands are instinctively planted against her thighs as you try to push against her. It was futile, she was just too strong.

"You wanted it boy? Then fuckin TAKE it!" With that she pushes three more fat inches down your gullet.

If your soul could orgasm it was doing so now. 'Yes! Yes! YES!!! Use your boy Mistress! Use me! **** me! Use your boy whore! Use me up!'

Your hair was being pulled. You were pinned against the wall. Your body was trying to wretch but couldn't. Your jaw felt like it was about to snap at the hinge. And you could feel your throat was bulging in your neck. You couldn't be happier!

"MMMLLMMMM!" You manage to hum, only to be reward with another inch. This mammoth monstrosity went on forever!

Still a few inches from bottoming out Fiona...just holds you there. "You like that? Huh? You like **** on cock?"

"Glllgggg!" You couldn't say anything. All you could do is gaze up at her in loving awe.

She nods. "I fuckin knew it!" With that she wraps both hands around the back of your skull, interlocking her fingers, and pulls you with irresistible strength the last few inches. Her cock filled your mouth and plunged down your throat past even where your neck met your clavicle! This was some fucking sword swallower shit. It is one of the proudest moments of your life as your nose nestles in among her thick tickling pubes.

"GLLG!" Your head is wrenched forward and up as your body contorts to take the straight girthy pole full hilt. "Gllg! Gllg!" Your body heaves and bucks but Fiona hold you firm. Your lungs are screaming for air and suck fruitless against the meat filling your maw. You continue to gaze up at your Goddess as she watches you struggle. Yet inside that cruel face...you saw love...you saw pride...you saw your sister. With every bit of strength you had left...you push her even deeper! Your nose jams against her and your chin presses into her balls.

Her eyes flare lustfully.

She holds you...and holds you...and holds you still.

Your body protests and heaves but soon even it submits to her as your spirit and mind already had. Things go eerily still for what feels like an eternity, though it was probably just a few seconds. You knew you were blacking out but you don't fight it. Your eyes locked on hers you feel yourself get light headed. Your vision begins to shade...

"GAUHHHHHHHHH!!!" You hear yourself suck in a huge gulp of air as Fiona suddenly withdraws from you. She'd taken you right to the edge! Huffing and panting for oxygen you manage a smile. Through your heavy breathing you gasp in raspy voice. "Thank you! Whooooo! Hahhhh! Thank you Mistress!"

Holding your hair in one hand she takes her cudgel in the other and begins slapping and batting your face. You snatch at it with your lips. You hungrily lick it. You kiss it. You move your face back and forth to feel it's girth club you. This marvel was YOURS! This was your Mistress. Your Goddess. Your cock to please. And please it you would!

Standing tall on your knees you open your lips wide and extend your tongue. To ensure you do not resist her this time you bring your hands behind your back and hold your left wrist tight with your right hand. You wait to be used like the whore boy you were. You don't wait long.

Fiona smears her massive knob down your face, from forehead to lips. A thin line of precum is painted along the trail. She pulls back...and RAMS her cock through your open lips.

"MMMMMMMMM!!!" You moan as you feel her slam into the back of your throat once more.

Your tongue is presses hard into your bottom teeth. Your top lip doing the same against the upper teeth. You wanted your Goddess to enjoy your face pussy, not nasty teeth getting in the way. Once again you cannot believe your jaw isn't cracking apart as you hold your mouth open at its absolute limit.

Palming the top of your head like and NBA player with a basketball she goes straight into a hard thrusting rhythm. With her free hand she slaps and squeezes one of her big tits.

"...glaw...glaw...glaw...glaw..." Your voice fills the room with rude sloppy noises.

"That's it! Yeah boy!" Fiona sneers. "You want this cock in that tight little pussy of yours you gotta fucking earn it!"

Earn it!? You'd run through a brick wall for it!

Redoubling your efforts you bob ferociously against her hard driving cock. Drool streams from your stretched lips and off the tip of your tongue.

"...shhglwww...gllauwww...schglunghhh..." You suck and slather your Mistress' lady dick with every ounce of passion you could muster.

"Awww FUCK!" Fiona exclaims. "By God you can suck a cock, whore! You're a fucking natural cocksucker boy! GUNGHH!!!"

She was loving it, and so were you. The pain in your jaw, the cock punches to your throat, the lack of oxygen? Trifling details. The main thing is you were doing a good job.

You service your sister's cock with everything you had, but her sheer size really made technique impossible. With Chloe you could tease and play your tongue against her. With this monster all you could do was provide an open sucking fuck hole. So that is what you do.

Your Goddess settles into a steady hip thrusting rhythm and just stays in that groove. She snarls and growls and snorts like a ravenous beast. Her free hand plays with one breast and then the other. Gripping and slapping her breasts and pinching her big stiff nipples with the same lack of mercy she showed you.

"...gllnghh...sschllrmmm...sllnggghh..." You are face fucked hard and fast.

"Yeah! Fuck yeah! Fucking take that cock boy!"

Your whole body was on fire. You are out of your mind with lust.

"...mmmm...mmmmm...mmmmmm!" You start to hum as your excitement grows to unfathomable heights. You could feel a steady drip running out your ass pussy and down onto the floor as your arousal hits a place you didn't even know existed. A constant stream of precum ran down the length of your dick and over your balls.

Sllllip!

Fiona exits your lips once more. You pant like a dog to get precious oxygen into you during this brief respite.

Reaching down Fiona again loops her finger into the ring of your collar and lifts you to your feet. She brings you right up to your tippy toes and holds you there.

Her face has a wild and deranged smile bigger than you had ever seen! Her hazel gaze roared with incendiary fervor. Pushing her hips forward and back she runs her enormous spittle drenched member up and down your stomach. Your own comparatively feeble organ poking into hers occasionally as she completely eclipsed you.

She pulls you close, bathing your face with her furnace hot breath.

"...nnmmmmm..." You whine submissively. You couldn't take much more of this. You were nearing an out of body experience here! "...mmmm...fuck me...please! Please! Goddess please!"

"You still wanna be bred, boy?" She snarls, spittle spattering across your cheeks.

"YES! Nnnnnnmmmmm! YESSSSS!!!" You pule pathetically.

"Well boy, you earned it...now fucking TAKE IT!!!" With that she spins and with one arm hurls you toward the bed.
