She takes your butt

"I want to give it to you in the butt." Zoe explains, looking down into your eyes, brimming with excitement. "I have a lot of semen stored, all for you my lust boy. This will be lots of fun, Marcus. Be so kind and rise my skirt." Guess no facefucking after all. But you never had it in your behind before and your hands are shaking a bit as they rise up. To your relief Zoes hands are also nervously thrumming her typical beat on the desk.

She expectantly looks down at you grabbing the lower edge of her maroon skirt and slowly pushing it up, making the buldge move down. With a abrupt "Pop!" her dick springs from under her pulled up skirt, almost hitting you square in the face. "There we go." you sister whispers happily as he meat pole bounces up and down from the recoil, levitating in front of your face as if its trying to hypnotize you. "Give your sister a kiss on the tip, honey boy." You obliege, bowing forward a bit and press your lips onto the head of her semi-hard cock, eliciting a girlish chuckle from your sister. She puts a hand on the back of your head, motioning to keep kissing, your lips already covered with some early precum and the salty taste of her stole itself between into your closed mouth. "I need you to lube it up first, otherwise it's going to hurt your cute little ass. And we don't want that. So be a good little brother and give your big sister a nice blowjob."

You hesitate reluctantly for a bit, which she notices. Zoe waits patiently until you made up your mind, while enjoying your kisses on her musky and growing shaft, crooning merrily. You finally decide to open your mouth and allow her entrance, which earns you an approving sound. "Good boy." she sings while shoving her hose into your mouth "Don't forget to put your lips over your teeth!"

Zoe puts her first few inches into your mouth, laying her meat onto your tongue and then stops, looking at you expectantly. "I leave the rest to you" she explains "Make it nice and slick." and she rests her hand on the desk behind her and leans back, pushing her doubls D's in full view. The taste of her salty-sweet precum is already conquering your oral cavity, as you start worm her warm phallus inside you.

You totally forgot how wide her cock is, as you struggle pushing more of it inside you, getting slower and slower as her shaft gets wider and wider. Not long after and you start gagging as her tip toches your throat entrance. You try to keep pushing, as tears run down your face and fall onto the ground, but you feel like its not moving at all anymore. Finally you back up a bit and release yourself from the struggle. Did her girth increase in the last days? Zoe notices your predicament and puts a hand at the back of your head. "Mmh. I guess it's quite hard to swallow it alone. Don't worry I will help you swallow it whole, little boy. Keep your hands on my dick to steady yourself."

Tears still flowing down your face, you rise your hands until you meet the warmth of her cock meat and grip it firmly. "That's it." she sighs at your touch. "Try to swallow it until it clogs your windpipe. I will do the rest." You shiver at the thought, remembering the helpless struggling for air the last time. But then you start pushing her meat into your mouth again. "Good boy."

Desperately pressing forward and under heavy **** and gagging, you manage to breach through your throat entrance earning you a soft coo and a pat on your cheek. Zoe watches you excitedly as you keep struggling with her wide dick, one hand still on the back of your head, applying light pressure, while the other one plays with your wet hair. Her whole mushroom head has now entered your throat and you feel your breathing getting difficult.

"I'm going to begin now." you hear her soothing voice above you, not seeing her through the tears. "Ready?" You give a short weak nod, not really delighted to have the same experience from Monday again. With and approving hum she grabs your head with both hands and then forcefully rams her dick into you. "OH GOD. THIS FEELS AMAZING" you hear her cry, as she closes off your air supply and plunges further down your throat. The maroon skirt moves a bit down her thighs, from the rapid movements of

violating your small throat with her monster girth and you soon move your hands away from her shaft and start swaying in slight panic. "Holy moly, where you always that thight?" Zoe sounds far away again, as she **** feeds you her last inches. You vision blurs completely, not only from the tears running down your cheeks like a waterfall. After a while of panic struggling, probably mere seconds in real time but feeling like several minutes for you, you are feeling lightheaded and like hovering in a vacuum. Her last inches finally make it past your indrawn lips making your nose greet her groin while her warm, bald balls fondle your chin. Your air has run out a while ago and black shrouds move over your eyes again, but you feel calm and collected, arms hanging down at your sides lifelessly. Zoe takes that as an invitation to give you a dozen short, rapid thrusts, fucking you like a ragdoll before pulling out her glizening member slowly, savoring every sensation of your wonderful throat, to your dismay.

As her whole 15 inches were out of your mouth again, dripping with your organic lube, you just fall over, face first onto her beige stilettos, not feeling the pain of the crash, not even sensing the fall or anything else. Only when sweet sweet oxygen touches your lungs again, your senses come back and make you aware of a sharp pain in your cheek, and the soreness of your violated throat. The black veils lethargically disappear from your vision with every breath, and you feel a warm gentle hand cup your head and heave you up into a kneeling position again, your vision still blurry. You can make out the shape of Zoe, bowing over you, saying something, but it's too far away for you to understand. So you just sit there and wait for the rest of your abilites to return to you, while you see you big sisters fuzzy shape move in front of you.

"Hey you hear me? Marcus?" her anxious voice rings out again, overly loud in your ears. You eyes focus seeing her worried face hover in front of you, her throbbing dick in the background, twitching cheerfully. "Good, you are back again." she starts talking as she sees your eyes focus on her. "You need to sign me that you are out of air, dummy. Just start hitting me or something but don't sit there and do nothing while I kill you with my girth." her words are sharp and stern. You usually have a thick hide, your sister Jessica helped you with that plenty, but now as you see Zoes worried face and the seriousness in her voice, your defences crumble. "I'm sorry, I don't know what happend." you mumble, more to yourself that to her. You avoid Zoes eyes. Her expression softens as colour returns to your face "It's fine, sweety. Fortunately, I just wanted to lube my dick and not fuck your face. We can work out how we handle future facefucks later, as I don't want to deny my cock your wonderful thight throat." A mischievous smile returning to her crimson lips, and her black wimpers and dark blue eyeshadow add to her seductive look, as she winks at you.

"Now, lets get you ready before the lube dries. Pull down your pants and present me your butt, my boy toy." Her voice is soothing as honey again, as you remove your boxers with shaking hands and turn your back to her. Your blushing face earns you an amused chuckle, which makes your heart race faster. "Come here and bend over the desk, for starters. And then try to relax. Your big sister will take good care of you, honey <3"

You comply, everything feels like a dream as you lay on the teachers desk and you hear Zoe move around you towards your head. You give her a confused look as she stand in front of you, dick twitching slightly. "I would prefer to lube it again. Open up, boy. I'm going to make it quick." A coy grin on her face as you obey. Then she lines up her dick with your fuck hole and puts a hand behind your head. It indeed was fast, as she burtally rams her meat pipe into your face, your gag reflexes can't even react when her whole length is already down your gullet. Your whole body spasms at her violent entry, as she gives you six short thrusts. And then it was over, as she pulls it out as fast as she pushed it in, threads of your salvia hanging now from her dick. "Good boy." she coos, moving to your ass, her stilettos clacking dangerously on the ground with every step.

"Relax, honey. It will hurt if you tense too much." you hear her behind you as she lays her slick shaft in between your asscheeks, and teasingly pushes it up and down on your ass crack. "I will enter slowly, but I still need you to calm down." You feel the wet warmth of her glans on your pucker, and try to relax as much as you can. 'Try acting as if you are dead.' you think to yourself and let all your limbs hang lifelessly. "That's it Marcus, keep it like that." cheerful singing from your back as her dick exerts pressure on your entrance. Zoe moves it in circling motions, slowly coaxing her way inside you. After a few circles her head finds grip on your hole, and starts streching your rose under your loud groans. More and more of her meat snake make it's way inside you and you reflexively cringe away from the sensation. "Mmmh that feels beautiful, honey. My head is already all the way inside. You are doing great!" Zoe commends you, ovlivous of your feelings but still managing to make you redouble your efforts of keeping your muscles at ease. One of her hands gently kneeds your back, as she gently starts to push in again. You groan as the girth at your little pucker keeps increasing, making your legs weak. Your ass feels like breaking, but her encouraging words let you keep going, concentrating everything on not concentrating anything.

Your own dick grows to full mast, pressing against the cool wooden desk, as Zoes girl meat kneads your prostate. Sweat starts leaking from your every pores as the pain of the warm invader forcing its way inside you jolts through your body like lighting. You bite into the edge of the wooden desk as Zoe keeps pushing her hose into your tunels, stimulating you more and making your cock twitch uncomfortably. "Good boy Marcus. You positively suprise me with the way you hold onto yourself. Keep it up and it will feel good, I promise. We are almost there." Her reassuring words are balsam on your sore ass. Your world is centered on the hot white hubs of pleasure and pain in your ass, making every muscle in your body limp as you sister finally buries her last inches inside you. "Shhh. It only going to get easier now." your sister leans over you and starts massaging your shoulders, letting her meat bar rest in your intestines. She lays down on you, pressing her soft ample breasts on your back, and gives you a few short humps, her orange sized balls clapping against your mandarines. "There we go, honey. Now we can fuck." Zoe whispers into your ear.

Zoe moves her hips in circling motions, making her cock explore your anal cavity. "This feels heavenly." she purrs and then starts to pull out a few inches making you bite the desk with your sore jaw again and groan. Your eyes bulge out at the sensation of her moving inside you, streching your intestines with her hard meat pole. Then Zoe starts fucking you in short and quick thrust, pulling a bit more of her dick out with every shove with the plan of making you accomodate to the feeling. Only that you are already overwhelmed by the feelings of fullness, pain and pleasure from her massaging your prostate, your whole body feeble like a sack of potatos. First girlish moans reach your ears as her jabs get harder. Smacking sounds of her balls and thighs against your asscheeks fill the room while she fucks you like a whore, seven inches of her meat hose entering and leaving your greedy ass like a well oiled piston. The **** of her thrusting pushes you forward, rubbing your hard dick over the smooth desk. "Don't escape, little rabbit. My balls a filled to the brim with yummy cream. All of it needs to be inside you by night. Otherwise you are not leaving." she accents her words with especially hard thrusts, while firmly grabbing your hips to keep you in one place.

Her first load of yummy cream shoots inside with the **** of a shotgun, accompanied by a short cry of her pleasure. If she didn't held you, you would have fallen off the desk. You feel like a dead animal being stuffed, the sensations of fullness captivating all your senses while your teeth hold on to tasteless wood.

"Oh god. I'm going to fuck you so hard, you little brat. I'm going to punish you with my big cum whip. You won't be able to go anywhere the next days once I'm finished with you." Zoe hisses while her hands painfully grip your hips, and her girlcock rams in and out your abused asshole, making you whimper with every thrust. You soon find yourself cum on the teachers desk from the constant prostate stimulation and her second climax arrives not soon after. You observe your sister succumbing to her animalistic desires, grabbing you by your hair and yanking your head back while her steel cock plows your little asshole making you tense your pucker for the frist time. "FUCK! YES! THIGHTEN YOUR LITTLE ASSHOLE AROUND MOMMYS BIG SCHLONG! GOOD BOY! HERE COMES YOUR REWARD" Your whole body trembles under the **** of her thrusts, moving the whole desk in direction of the closed window with every smack of her groin on your ass. The transformation of your sweet bigger sister to a lustful sex demon hits you like a truck, as Zoe pulls you into an upright position by your hair, followed by your cries of pain, and then climaxes into you again pushing you off the desk as she crams her girldick all the way into your shit hole and shoots a second load of hot, slimy girl spunk into your ass while you still can feel the first one washing your insides.

Some of her previous self still in her, she changes her grip from your hair to your neck and chest, while her relentless fucking continues. You whole mind is blank and white stars dance in front of your eyes, while pleasure and pain fight for domination over your senses.

After several minutes of getting **** by a crazed sex demon, your mouth sending drool in all direction and your hard dick jumping up and down, she puts her third package of hot semen inside you, white cream already spilling out from your ass crack. Then she slowly slides out of your fully lubricated insides, holding you with both hands in mid air.

"Everything Ok, honey?" her breathless whisper in your ear, accented by lust and hunger "I hope I wasn't too rough on your little body. Not that it matters, I have still some warm dick juice to offer you." She turns you around, still in mid air, so you are facing her. Sweat glistenings on her face, her crimson lips form a perky smile and her eccentric hairstyle, to your suprise, is untouched from her wild fucking. You don't have much time to muster her further, as you feel her big mushroom at your streched anal entrance again.

Zoe starts fucking you again, balancing your whole weight on her hips and hands while bobbing you up and down on her shaft. Your hard errection rubbing against her covered tummy didn't seem to distract her at all. Her gleaming eyes focus on your red sweaty face and the expressions of pain and pleasure you make while being **** to ride her.

"Put your legs around my hips, this might get a bit messy." Her tone more commanding than asking. You weakly rise your legs around her, you muscles screaming and the fact that she just keeps fucking you doesn't help either. She pulls your head into her covored breasts as her horse cock pummels itself into the depths of your rectum and you feel your insides being rearranged by her thickness. You grunt into her breasts, the smell of chestnuts together with her sweat hitting your olfactory senses. Antoher geyser of girl spunk flows from Zoe, her moans resonating in your ears. You feel it creeping up your colon, a wave of warmth, and dripping out of your asshole while you cling to her, feeling like breaking at every moment. Your own dick spurts ropes of cum over her beige blouse from the endless prostate massage.

She pulls your face out of her breasts and stopps fucking you for a moment. "Rip my blouse off. I want to feel your skin on mine when I fuck you over the finish line, boy." Her eyes full of desire, her lip movements cast a spell over you, almost making you forget her words. Your hands move up and start opening her blouse buttons, revealing her soft flesh. "I said 'rip', boy. I want to fuck you senseless now. Not in two hours." You start ripping on her blouse, your arms feeling empty. Somehow you still make her buttons fly, and her big tits jump right into your face. Her own hands impatiently opened her brown leather belt around her hips, throwing it to the ground and tearing the lower part of her blouse. "Thats it. Good boy." she coos lustly as her fit upper body lays naked in front of you, her ripped clothing hanging lifelessly from her arms.

She pushes your head into her sweaty cleavage and starts fucking you again with newfound vigor. Her breasts jiggle at the side of your head, slapping against your temples and ears while her cock takes deep plunges into your anal region, making your own cock twitch and throb against her naked navel and stomach. You feel her hands at your back as she pushes your body closer to hers. "Fuck fuck fuck this is great." her shrill moans are chopped off by her full milk jugs pressing on your ears. Zoes pelivs hits you like a truck whenever you fall down on her dick and pushes you up again with the power of her strong hips, making your face slide up and down between her round tits. Streaks of pain shoot through you as her rhythm speeds up, and you put your arms on her back, pressing yourself against her slick body while she violates your ass.

Your ass is soaking with her spunk, puddles of white cream are at her feet, as she orgasms over and over in your ass, her unsateable meat pole shafting you without pause. You have a tinnitus from the constant slapping of her breasts into your face and Zoes loud moans while your vision is a field of white lighting with every push of her hips and your eyes turn inside your head from the feeling of your overstimulated G-spot. "Oh god!" you hear her cry, as she pulls your head out of her breasts embrace and rams you into one of her tits with both hands. "Suck my nipple like you are dieng of thirst, boy!" Her sharp voice audible again, as you greedily take her pink hard nipple into your mouth and start sucking like a baby, while her meat shaft makes slurping sounds entering and exiting your cumfilled asshole. Zoe smothers you in her soft breasts, trembling under the wonderful sensation of you, her little brother, trying to drink from her big milky boobs. She answers your wanting appetite for her breast milk with another shot of dick cream up your rectum. In a last outcry of pleasure she buries her whole 15 inch shaft inside you, her balls smacking against your butt cheeks from the power of the thrust.

You feel the last spurts of her cock milk entering your intestines and colon while her climax slowly subsides a last time. Mouth still hanging at her nipple, her grip on your head reduces, letting your nose touch air again. You feel her silky hair on your cheeks, seeing deep black strands falling down over her exposed breast out of the corner of your eye. "Keep right at it, honey boy." she answers your attempts to pull away from her boobs, having you suck them while she lets her final climax fade away. Your legs are cramping, still locked behind her back, but the length of her girl cock is still up your ass forcing you to keep your position if you dont want to be impaled by her.

Finally, after three minutes of agony she heaves you off her gleaming cock and lays you onto the teachers desk.

"You did well. I'm proud of you, little brother <3" her voice soothing and warm, like a flowing river of honey, entering the pavilion of your ear, charming its way into your mind, relaxing you. You can only keep watching the white ceiling of the classroom, recognizing the dart, a classmate threw up there in a borring math lesson, as a blurry shadow. Every muscle in your body is far beyond its limits, refusing you any more service making you feel helpless and shakled. You feel Zoe sitting down on the edge, next to your head, the warmth radiating from her body, her hands gently stroking your cheeks and hair, and her face finally coming in view. She had removed the three sticks which held her hairstyle, her hair now cascading down like black water. She presses a soft kiss on your forehead and you can feel the kiss mark her dark red lips leave there. Her chuckle after Zoe looks down at you again, only affirms it. "There are some showers on the ground floor. Lets wash ourselfs in hot water and then head home. I borrowed moms car, so don't worry about limping home with your sore ass." Zoe giggles.

Then she flicks you up into her arms, as if you weight nothing, her torso still naked. You are mesmerized by her bouncing boobs as she strides towards the classroom door, picking up your clothes and shoes halfway and laying them onto your body. Switching off the lights in the classroom, Zoe makes her way down the dark school hallways, her half errect dick swaying between her legs under her skirt, making smacking sounds and dripping cum while your own hurting ass leaks drops of her girl cream onto the ground. Zoe pushes you into the side of her naked bosom, enclosing you in her warmth and love as she starts descending the stairs.
