I take a deep breath and push my cock like a sword into her butt. Seconds later, she covers her mouth and screams through a muffled mouth. I hold my hips firmly, not wanting to cause Sophitia, my sister, any more pain. The skin on her back turns red, indicating she is struggling with the pain of my thick, long cock piercing its entire shaft into her ass. She's taking at least a twelve-centimeter thick cock and an abnormally long jammed into her tight virgin anus for the first time. I give her as much time as she needs as she takes heavy breaths and whimpers slightly.
"B-Baku… K-Keep… G-Going…," she commanded through gritted teeth.
"Going hard, you mean?" I hesitantly questioned.
This time, Sophitia's head butt, but not as hard as I knew she could.
"Aha… Stop… Talking… A-And… A-And… D-D-Do what… Y-You… D-Did earlier… E-Err… B-Baku… S-Stupid… B-Baku," Sophitia demanded again with gritted teeth.
She struggled to get each word out as she squealed, whimpered, and moaned. Her breathing is like that of a lioness as she wildly pants. Not wanting to delay any longer, I withdraw my schlong until my mushroom tip remains inserted within her butthole. Then, in one swift thrust of my hips, my cock rams like a piston into Sophitia's bubble butt, causing a sharp smack as my hips pummel like a press into her rounded bottom.
"Aughhh! Owww! My… Ughhh! Harder!" my sister yelped.
"Soph…" I blurted.
Sophitia growls like a lioness.
"Aughhh!… J-Just… S-Stop… T-Talking… Stupid-Baku… Just… Harder… Now!" Sophitia yelled with animal-like growls.
My hips twist with each powerful, pounding thrust into her fluffy butt as she squeals loudly as she can. Her hips push up and down, forcing my cock to plunge as deep into her tight ass as she could take. My powerful hips buck into hers, causing her hips to lock my cock like a plug in her tight ass. That tight ass of hers was taking an identical pounding as her pussy had for hours. My eyes lock on her clapping tight ass cheeks like ripples in a pond. Her pussy lips squirm as Sophitia's fingers stimulate her soaking wet vagina. Her fingers press against her sweet, perfect cunt as feminine fluid bursts forth from her soaping, wet cunt.
"Aha-huh… Ughhh… A-Asa!"
My cock throbs in her tight ass and twitches, and my cock pumps hot, white, steamy cum into her tight asshole. I can tell that her tight ass is getting tighter by the moment, as if her anus was a devourer of cocks. Her thick, swollen clit continues writhing throughout my cock, as I jackhammer into her bum hole. With each thrust of my penis through her tight, thick, wet cherry pop, her moaning and whimper fueled my erotic lust. Sophitia was like a succubus as she drained my cock of its life-giving seed. My schlong rams her ass, and she feels full, so full, and so delicious that after only a couple more minutes of cumming uncontrollably into her ass, Sophitia growls.
"Fill me, Asa… Fill me until I'm full!" she cried like a lioness.
"Sop…" I blurted, but she cut me off.
"Ughh… Hush! Harder… Aha… Harder… B-Baku… S-Stop talking… And… Take me… A-Asa!" Sophitia shouted.
I cover her mouth as she lets out a loud cry of surprise when I shed all my hesitation as I do as she commands.
"As you say… My Lady Sophitia…," I whispered in her ear.
In response, she wiggled her hips, pushing her butt into my crotch. I flip my sister over, throwing her long, ballerina legs over my shoulders. Gripping her thick, childbearing thighs, I plow into her anal cherry as I watch her breast flop every which way from the power impacts of my hips. In seconds, I was pounding her booty with ferocity. She holds onto my hands as I buck into her back and forth in quick succession. The sounds of flesh clapping caused a commotion in the stable, but I didn't care. As I looked down into her eyes, I pounded my sister's butt with unleashed fury. Her grip on my hands was inhuman, and a smile came over her face as she moaned and whimpered from the onslaught.
"Oh, Asa, umm… Brother," Sophitia moaned.
"You are mine, Sophitia… I want you to be mine," I said through grinding teeth.
I grunted like an animal, pumping into cock hard and deep into my sister of this world, Sophitia's tight cherry ass. Her bottom hungrily accepted the entire length of my elongated tree trunk of a cock with a primal arousement and a brutal, inescapable erotic lust I'd never experienced in my past life. Sophitia radiated a brutal, erotic, arousing aurora that seemed to engulf me as if I were prey. The word' Mine… She's mine,' flooded my mind like a virus. I lean over Sophitia, looking at her in her cerulean blue eyes. Her voluptuous double F-sized breasts jiggled like apples in a strong breeze. Their enormous size only emphasized her curvaceous, yet ballerina, slenderous, coke bottle physique. I smile as I reach around each of her well-toned legs to twist my sister's perky, plump nipples.
I spread Sophitia's legs wide, one hand holding her right thigh, and my other hand grips my sister's ripe peach-shaped ass. My movements are swift as I buck my hips in and out like a freight train. I don't slow my motion as my hard thrusts are full and impactful, like the hammer of a magnum revolver. My sister's breasts jiggle like jelly and bounce with each impact. Sophitia's eyes never leave mine, and I feel a powerful wave of heat in the feed room. It was as if the room was on fire. Her eyes held such intensity and wanting desire that it overwhelmed my mind. Sophitia's long, golden blonde hair spilled all over the floor like a lion's mane. Her mouth is agape as she pants like a wolf, her teeth glistening in the moonlight.
She arches her back, and I can feel her face as she grips my shaft and continues to squirm and moan. My hands move up and down her body before I slowly push my cock deeper inside her. One of her hands rubs my cock as I grind into her butt, while the other fiercely rubs her cunt. The thought of her cumming from a brutally hard anal pounding hard and tight is stunning. 'Sophitia is taking a pounding as if she is a veteran pornstar.' I can feel her gyrating her hips, pressing in against the head of my dick and my balls as penetrating her butt hole like a rampaging rhino. Suddenly, my body quivers once more then I buck like a bull into her ass.
A torrent of my hot seed exploded like an erupting volcano and came faster in the light of my excitement. I fill my sister's anus with a load after a load of milky, cream, hot semen. With one last pump, I let her legs fall from my shoulders as she rolled on her side, exhausted, as did I. We lay there for a long time. Neither of us says a word. It was like making love to Abigail. Only I was more endowed and had an abundance of stamina. I knew I could go many more times, and I felt I could last all night with this new body of mine. Finally, after several long minutes, my sister nudged me. I held her close, and she looked over her shoulders at me. In the dark, I could see her as clear as day. It felt like only minutes had passed, but the reality is several hours had passed during our erotic, intimate sessions. After a long while, the two of us turn towards each other. We just watched each other for a long time. Sophitia is the first to break the silence.
"You can't tell anyone else about this. It stays between us, Lord Asa," Sophitia whispered.
She brushed aside a few strands of hair that had fallen over my face. There was no anger in her voice. She was just surprised that this was a reality and that it happened the way it did, and she smiled. Sophitia gestured as she turned around, and I felt her snuggle into me. Her bare butt caught my arousal again. I couldn't stop myself from groping her breasts. She let out a whimper as I pinched her nipple. My hands caressed her teardrop, cantaloupe-sized melon breasts. She snuggles up to me, pressing my body into the wall of the feed room. I hear her mumble, and I know she feels my cock grow harder by the second.
"Want to go again?" I asked.
"Seriously, Asa??" my sister whispered, looking over my shoulder at me.
"Seriously," I countered.
She made a face that sent me into yet another erotic frenzy.
"Fine, but you better not mention this to anyone," Sophitia whispered as I felt her hand guide my cock into her pussy again.
I had a feeling I'd have a few more runs at that butt before morning. With her words, I rolled her onto her stomach again, gently kissing her back as I mounted her from the rear. My cock pressed into her pussy, prompting a whimper of pleasure. She grunts but relaxes as she waits for what comes next. We had a whole night left. I knew this was going to be an all-nighter.
