Sister Fister

Fiona gives you just enough time to recover your senses before she slips two fingers into your hole. It...was...incredible! You had never before experienced such a deep and powerful need to be...filled, but you were feeling it now and these two fingers were a delightful appetizer. With you wet and fully aroused there was no unpleasantness or uncomfortableness. Her fingers felt like they belonged there. It was fantastic. You spread your legs wider, within the limits the ropes allowed.

"Yes!" You gasp.

"Doesn't hurt?" She asks, studying you. "Even a little?"

"Oh my god no! It feels...ohhhhhh god!"

Fiona was all smiles as she begins slowly and deliberately fingering you, feeling you and learning about your body in the process. "Fuck Jesse, you are so wet. I don't even think we'll need the lube!" In...out...in...out, she fingers you slowly and lovingly.

"Ohhh. I love you!" You say. You weren't exactly thinking straight and it was the first thing that sprung to mind.

She smirks in a playful way. "You're just saying that cause I'm finger blasting your asshole."

You shake your head vigorously. "I love you! I love you! I love you! God, I love you!"

"Okay, okay." She chuckles lightly at your uncontrolled ejaculation of emotion. "I love you too precious."

"Mmmmmm!"

Turning her hand palm up she curls the two fingers inside of you and explores. Her firm rubbing fingertips stroking forward and back along the front wall of your tunnel. It is not long before she zeros in on an incredible little region of butt centered happiness. Like your dick and your clit, this was another incredible feeling erogenous zone. Different again, but so fucking good.

"OHMMMMM!"

"There it is. That's nice, isn't it baby." Her fingers move with confident grace. In and out of your asshole smooth and steady.

"Uh huh!" You squeak.

She wonders out loud. "I wonder if your p-spot is also your g-spot. I wish I knew what you were feeling right now."

"Unnnghhh! Feels gooooood!" You whimper. "Feeeels soooo goooood!"

"I can see that." With you barely aware of it she slips a third digit into your entrance, the extra girth was welcome. Your muscles relax, your eyes roll back in your head, and you were sure you must have a hazy far away look of bliss on your face. Fiona's finger banging was everything right now. If you couldn't have her cock this was the next best thing. In and out her fingers go, building in power and pace as she carefully learned what you could take.

"OHHHMMMMMM!!!" A fourth finger joins the rest and with a flat blade of a hand she changes it up and starts banging you harder, her extended thumb slamming into your boy clitty on each rough thrust. "FUUUCK!"

"Yeah! Yeah! Yeah baby!" She growls through clenched teeth. "You can take it, can't you baby?"

"Yes! Yes! God yesssss!" You feel the steady stream of precum flowing from your straining rock hard manhood smear over and through the ropes and onto your belly. "Yes Fiona! I'm a sexy slut, I can take it!"

"Ohhhh! A slut is it?" Slam, slam, slam! Her hand pounds you hard enough to rock your pretty pale body. "My pretty boy is a pretty little slut huh?"

"Yes! Oh God Fiona, I'm your pretty little slut! Use me. Use your slut." The words, the deeds, the feelings. It felt as if your life had built to this moment. You felt as if this was where you were born to be. "Unnnnnggghhhhh!"

"Well then my sexy slut...FUCKING TAKE IT!!!" With those words she takes the next logical step. On the next thrust she pulls her hand back and tucks her thumb in amongst her fingers to form a cone of her hand and with barely missing a beat plunges it HARD into your pussy! With the thumb no longer there to provide a stop she punches six inches deeper than she had been going. The feel of stretching out around her fist then tightening back down around her slender arm was...was...

"GUNNGGGHHHHHH!!!"

The sudden feeling absolutely exquisite fullness is a **** unlike any other and your unprepared flesh does the only thing it knew it could. A raw pleasure with an intensity that bordered on erotic agony you are hit with a white hot bolt from the blue. Your body spasms and shakes and you feel your warm jism blast out over your chest and stomach. You feel your sister's hand form into a tight fist inside of you as she begins thrusting violently in and out, her fist staying inside at all times as her forearm slips forward and back through your tightly wrapped sphincter. You could feel her forearm get slightly thicker toward the elbow as she punched into your bowels, then narrow off again toward the wrist as she pulled back.

"Ohhhh fuck, already? Ha ha ha! That's it baby. Cum for me! Cum for me!" You feel her balled fist plunging inside of you. Stretching you and filling you the way you needed to be.

"GUAAAAOHHHHHHHH!!!" Thick juicy wads of cum erupt from you, one after another after another after another. You wondered if it would ever stop! Simultaneously you then feel your pussy clamp tight and those deep warm waves of womanish orgasmic release joins the rapturous cacophony of fleshly pleasure.

Fiona's arm fucks your hole for all it was worth. With you writhing and moaning like the slut you said you were she continues to urge you on. "That's it baby! Ohhh shit, gonna squirt for me now too huh? Yeah, yeah, give it to me brother. Cum for Fiona!" Leaning down she plants her tongue onto your clit once more and you hear loud wet slurping sounds as her arm continues its anal ****. Her free hand reaches up to massage your pulsing balls.

"Unnnnhhhh...uhhhhhhh...uhhhhhh...ahhhhhhhhh..." Your cries of release coincide with the throbbing duet of simultaneous orgasms going off inside of you. Every muscle locks up and you simply vibrate inside your rope bonds as Fiona relentlessly fucks your quivering asshole. The only way this could be better was if this was Fiona's cock inside of you instead of her arm.

You have a vague sense of cumming a second time, though it really all blurred together now. You just knew both your cock and pussy were going off in ways that blew your fucking mind. The smell of sweat and semen and pussy and ass all fill the air in a musky perfume that was uniquely your own. The ropes digs into your soft skin as you flex and heave. Your voice rings out as you lewdly express yourself and what you were experiencing.

"Uahhhh...unnhhhhhhh...ahhnnnhhhhh...ahhhhhhaahhhhh..."

It goes on and on though you had some sense only a few minutes had passed. In your world it was an eternity. Your hands grip the sheets and you hold on with all of your strength. Fuck...that fist...that fucking deep thrusting FIST!!!

"GUNHHHHHHHHH!!!"

As with the tickling, you hold out as long as you could. But this was just too much all at once. You might be a slut but you were an inexperienced one. With an almost pained voice you mewl. "Snake....snake...sssnnaaake....uhhhhhhhhhh!"

Fiona doesn't stop all at once, that would have been cruel just then. Her pace rapidly slows and she gives you three deliciously long slow deep thrusts before she folds her hand as narrow as she could make it and very gingerly slips out of you. You peep as thick part at her knuckles pop out of your hole followed by her tickling fingers. You feel the air rush in as you gape wide for a few dizzying moments. God, the emptiness was nearly unbearable! You feel your sphincter gradually tighten and pucker closed.

You look down at your sister in a drunken stupor. You try to speak but all that come out was long puling high pitched noise. "...aaaeeeoooommmm..."

Fiona was...impressed. Very impressed. She was damn near awestruck. "Oh Jesse. Good boy! Wow!"

You slowly realize your chest and stomach was absolutely slathered with creamy oozing jizm. You must have blown every last drop of cum you had out onto yourself. Your boy pussy was alight with a pulsating beat that simply magical. The muscles of your neck give out and you slump back again. If you thought you were a puddle before you didn't know what you were now. You felt formless, like you might just ooze out through the ropes and off the bed to the floor below.

You whimper and moan as you lie there, convinced you had found heaven on earth. Your sister made you feel this way. Your big sister helped you find heaven. That powerful memory sears into your addled mind.

Fiona reaches back and takes some of the wet wipes she had ready. She cleans her hand and wet arm then proceeds to lovingly wipe your used and abused tush. The slick cum across your body she leaves for the moment.

Crawling up beside you she snuggles in close and cradles your head to her soft pillowy breasts. "Ohhh sweet thing. You did so good!" Her fingers tenderly strokes your sweaty hair. She was so proud of you, so happy with you, it was humbling. "My precious boy. My beautiful brother. You did so good baby. Ohhh, you did so good." She kisses you.

"...mmmmmmm..." You close your eyes and lean your head into her warm tits. You kiss one and just lay there in easily the most intense afterglow of your life. In the encompassing afterglow of a double orgasm, in the loving arms of your sister mistress, you feel a happiness bloom that went far beyond the pleasures of the flesh.

Fiona holds you to her and continues her soothing words and gentle stroking and soft kissing. "My good boy. My good good boy. My special perfect pretty little brother. Goooood boy."
