Fantasy Land

My twin brother Adam and I often were left home alone during the day while our parents worked. We knew how to take care of ourselfs and had phones and neighbors incase of an emergency. We were both in the basement going through stuff that was stored there. Some of it had come from our grandparents after they passed away and we were curious. There was a bunch of old looking books, exept one. I picked it up reading the cover. It said Fantasy Land in fancy text. Hey look at this! Whats that? He looks over my shoulder. I dont know it was in the other books but it doesnt look old. Hmm open it he says. So i lift the cover. As soon as its open a light beams from inside, and i feel it shaking in my hands. I drop it, what the fuck?! Before either of us can get an idea whats going on the light gets brighter, seeming to surround us. When it subsided I looked down. We were standing on grass! I turn to Adam. He was obviously trying to process this too, but I was glad he was there too. We looked around noticing we were in a big feild bordered with tall trees. There was a huge castle standing above the trees in the distance. Jessica? Adam looks at me. Where are we? I have no idea i reply. All i know is it cant be a dream if we are both here. He nods. The book is gone too. What? Then how do we get back!? I have no idea.. The only thing that suggests anyone lives here is that castle. So id say lets go ask them he says confidently. Ok.. Trying to keep from panicking i grab his hand. He doesnt say anything as we start walking toward the trees. Its quiet, im wondering if theres any animals in the woods. Maybe we shouldnt go in there.. Your welcome to stay here he says, but im going to that castle. Entering the forest. I can't stay here i think to myself. I follow after him. Immediately after we pass the treeline we realized how dark it was. We could see just enough to avoid walking into trees. Im just following right behind him as we get deeper. Then i hear a rustle of leaves. Stop! I whisper. What? Adam looks around. Whats wrong? Did you hear that? The rustling grew louder, like it was getting closer. We are both shaking, unsure what animal it could be. All of the sudden a shadow loomed over us blocking the little light we had. I tried to scream but a hand was placed over my mouth and I was lifted into the air. More hands tied my legs and my hands together. They felt like human hands. I tried to look at them, but was tossed over a horse next to my brother. He was also tied the same way. They brought us out of the trees, thats when we actually saw them. They werent humans, and we werent on a horse. They were centaurs! There was two that came out of the trees with us. They pulled us off the other one and dropped us on the ground. I was in aw, staring up at them. Not thinking of what they intended for us. They laughed as they reached out and took hold of my shirt and shorts ripping them off with ease. I gasp blushing, i try to move away. Still tied tho im unable to do anything as they do the same with my bra and panties. Now compleatly naked i close my eyes feeling their hands touch me all over. One pushed his fingers into my pussy, i gasped my eyes flying open. Thats when i saw Adam. I had compleately forgot he was there too. He had also been stripped and i watched as he was tossed face down onto a large stump. I was lifted up and brought over to a similar stump and layed over it. We were facing eachother as a centaur walked up behind us both and put their front hoofs on the stump on either side of our heads. Thats when i saw the massive cock dangling under Adams assailant. Feeling one rub up against my ass at the same time. There was no way we could survive getting fucked by those! The one i could see was easily twenty inches long and as thick as my thigh. I couldnt look away. watching him line up the tip of his cock with my brothers ass i felt the same done to my pussy. I saw the fear in his eyes and he cried out when the tip forced his asshole to stretch around it. Then i felt myself being gaped open and filled with what felt like a football. My eyes rolled back and my mouth opened to scream. I couldnt belive a stayed conscious. Then with a grunt he thrust into me. It felt like i was split in two, it penetrated deep into my womb making my belly buldge. He started pulling it back and slamming it back in hard and fast. I was in tears my body limp on this giant cock. The pain slowly faded and i looked at my brother. He was staring blankly, his mouth open in a silent scream. His asshole taking every inch of that cock over and over. After what felt like hours, they both slammed their entire cocks in us. Holding them there, i felt a pulsing feeling before hot liquid started squirting into me. I could see Adams ass being filled as well our stomachs both growing round. With a satisfied sigh the one in me pulls out, at least a gallon of cum flooding out after it pops out. Adams did the same. His asshole looked like a cave with cum gushing out like a waterfall. Maybe they will let us go now i think. But then i am reminded that there were three of them.. The third one picked me up and brought me over to my brother. Placing me in front of him face to face almost touching noses. I watched Adams eyes look behind me and widen. What? I ask nervously. He looked at me in the eyes. They saved the biggest for last. How big i.. I was cut off by the cock head being placed against my asshole and forced inside. I let out a scream while it was plunged deep into me. It filled my stomach, then it just kept going. I felt it slide under my chest and suddenly i couldnt breath! My mouth was open and i felt my throat opening allowing the tip of the cock in me to slide through and over my tongue to leave my mouth. I dont know how it was possible but i was still alive and awake with this cock sticking into my asshole and out of my mouth compleatly impailed. I could only look at my brothers face as it pushed its way past his lips and into his mouth. It forced its way down his throat. We were both stuck, mouths wide around the thick cock. Then he started fuckinh us. The feeling of my entire body being filled was incredible. I dont know how long we must have been like that before he started blasting loads of cum into Adam. When he finally pulled back and the tip plopped out of my brothers mouth, cum flowed from his asshole and his mouth at the same time. When he was out of me the three ran off leaving us there with gaping holes and cum puddled up all around us and still running out. We both roll over off the stump and untie eachother. We dont say anything as we lay there and we fall asleep.
