My Sibling Teacher

[Only_yours]

I knew he was getting close even before he told me. I had enough experience with blowjob to catch the first signs. I espcially loved it when I could feel the cocks pulsate and expand slightly in my mouth. It always gave me a nice rush.
I wondered if my brother expected me to pull away, but I certainly had no intention to do so. instead I just moved up so that only the tip of his cock was in my mouth before I used my hand to jerk him off.
Then I felt it, the first shot of cum in my mouth, quickly followed by another and yet another and another. Rather amazed by the large amount of cum my brother was producing, I had a hard time trying to swallow it all. Although it was more than wrong, I wondered what it would be like to feel so much cum splashing inside my pussy. I had briefly been on the pill and had enjoyed bareback sex, but the guys I had been sleeping with back then had never produced that much. After a while I had given up on the pill as I found myself forgetting too often and instead forced the guys to wear condoms. There was no way I would be getting pregnant by any of those immature guys who didnt even have plans for the future.

I felt the last spurts fill my mouth and I happily swallowed everything, even licking his cock clean before smiling happily. This had been my brother's first blowjob and I had been the one to give it to him. For some reason, I felt more connected to him than ever before.
"Did you like it?", I asked, even though the answer was blatantly obvious. And it was rather weird to ask him a question as I was still practically sitting on his face.

I don't think I could remember the last time I came so hard. My sister's mouth brought me to such and intense explosion I swear my eyes must have rolled back into my head. Every spurt burst into her mouth and I couldn't believe she was swallowing it. I was cumming in my sister's mouth! That thought only made me cum harder.

Finally I slumped under her, panting hard and heavy as I tried to calm my heartbeat. My sister moved up and turned toward me, giving a naughty smile my way. "That was insane sis. I never felt something so amazing." I shivered under her and laughed. "I have missed out so much on things like this. Christ if I knew things would feel that good, I would have done worse in school and gone after girls more."

I sat up a little and took her hand. "I mean christ sis, that was only a blowjob. I can't even imagine what sex actually feels like. I mean if it is better than that, I think my head would fucking explode." I told her.

When he laughed, I could not help but join him. "Oh you definitely missed out. But we need at least one academic in this family to make up for my stray ways.", I joked with him, shifting so that I was sitting next to him on the bed. When he began talking about sex, I got a dreamy look on my face.
"Ohhh, its sooo much better.", I told him. "Pussies are usually a lot tighter than mouths. And girls definitely enjoy a cock in there much more too."

Seeing as I hadnt cum, my mind was racing with thoughts about sex. I needed something to fill my pussy, but could I really go all the way with my brother? I looked toward my drawer and remembered that the condom box I kept for nightly visits by male friends was empty. Dammit.
"You dont happen to have condoms, do you?", I asked, not caring how he would take that question. "Im just so bloody horny right now..."

 

[musicankane]

She taunted me by explaining how good pussies felt. Tighter and wetter than a mouth huh? I smiled at the thought of being inside of a girl. I thought about being inside my sister, I thought about that pussy of hers that had been so close to my face just moments ago. I could still picture the tight little hole she had, the slick wet warmth I had felt that came form her. I must be sick, thinking about putting my own dick inside my sister.

I watched her lean over and reached into a drawer beside her bed. She frowned and looked at me to ask for condoms. I blinked and shook my head, "Condoms? No I don't. I uh, never thought about needing them. What do you want a condom for?"

I sat up and looked at her, "Shit do you have a guy coming over? I'm sorry sis, I didn't know."

 

[Only_yours]

"Dammit.", I muttered again when my brother confirmed what I had already expected.
"No, Im not expecting anyone tonight..Its just that sucking your cock and you playing with me has gotten me really horny and wanting a good fuck."
I couldnt believe what language I was using in front of my brother, but right then I didnt care. My pussy was eager for some action and I knew that some regular masturbation just wouldnt satisfy me the way I needed.
At that moment I was angry at myself for having borrowed my best friend my vibrator for the week.

Without thinking about it, my hand sneaked between my legs, slowly rubbing my slit to give myself at least some stimulation. It didnt matter that my brother was sitting right next to me. In fact, as I looked at him I saw him as the only solution to my problem.
"I helped you out, so now I ask for a favour in return. I need to cum really badly, big bro."

 

[musicankane]

I stopped and turned toward her. I never thought I'd hear my sister say such things, and it made me excited. Even though I had just came, I felt myself getting turned on at her language. When I glanced back at her, she had her fingers between her legs and she was rubbing herself. RIght in front of me, she was just rubbing herself like crazy.

"Help you out?" I asked, then slowly I smiled. "Yeah sure I'll help you sis. Want me to eat you out some more?" I turned toward her and got on my knees on the bed. Little did I know my cock had gotten hard again and pointed right at her. IT was almost as if my dick was pointing itself right at her cunt, as if it knew exactly where it wanted to go.

I saw my sister in a new light then. No longer was she my sister, but she was just an extremely beautiful woman that I wanted to fuck. Oh god, something was fucking up with me, because I wanted to fuck my sister.

 

[Only_yours]

"No, I need something to fill my pussy.", I said, slowly getting more frustrated. "I know I am crazy, but please, just fuck me."
I was practically begging for incest there, but my brain was too occupied with sexual release to think of much else.
"I am so horny I will probably cum in a matter of minutes. Can you hold off cumming for that long?"

It was silly even thinking about fucking without condoms, especially my own brother, but surely there was a way around this.
"I promise I will give you another blowjob if you do this for me.", I promised, leaning back on the bed and spreading my legs invitingly.
"Please, brother. I really need a cock in me right now or I will go mad."
I was just that much of a slut, I couldnt help it.

 

[musicankane]

I blinked in shock at my sister's words. She wanted to fuck me? I couldn't believe it, this wasn't supposed to go so far. We were about to go beyond the point of return, if I put myself inside of her then we'd be fully incestous bastards. I smiled as she laid back and allowed me to see her. The way she was on her back with her legs spread it was like she was giving me permission to mount her and explore her womb with my hard shaft.

"I can try sis. But I mean shouldn't I really get a condom?" I asked. If we were going to have sex as brother and sister, then we needed to prevent the risk of getting her pregnant right? I mean we'd be dead meat if our folks found out we fucked, and it would be hard to hide a pregnant belly.

I moved toward her, crawling over her and letting my cock move toward her slit like a heat-seaking missile. I knew I had just asked about a condom but my desire to feel what sex was like was overshadowing my doubts. I wanted her, I wanted to feel her around me and I wasn't going to back down now.

I reached between us and pressed the tip of my cock to her hole. I looked into my sister's eyes as I felt her body open around my length and I entered her. "Oh shit." I gasped as I lost my virginity. I wanted to go slow but I couldn't stop. My hips pushed until I was buried to the hilt inside of her. I began to move my hips uncontrolably, thrusting into her quickly. "Oh god sis, this feels incredible." I moaned.

 

[Only_yours]

"We dont have time to get condoms. Just pull out in time." I tell him as I am getting truly desperate. Finally he moves over me and I sigh when I feel the tip of his cock at my pussy. It doesnt take long for him to finally slide into me. My pussy is all wet and embraces him happily, almost greedily sucking him in as I moan happily.
"Fuck yessss." Its exactly what I had needed.

There was no beating around the bush as my brother started to pound away into me, making me gasp every time he plunged his length back into me. I had no trouble meeting his rhythm, eagerly pushing back at him to get him as deeply as possible.
Perhaps I had been stupid to expect him to last long considering it was his first time, or perhaps I had underestimated my own lust. But before I was close to cumming and there was no way I could let him withdraw before I felt my climax.
So I wrapped my legs around him, pushing him into me as I began thrashing on the bed, screaming to him that I was about to cum any second.

Finally I felt my desired release wash over me as my pussy clamped down on his cock, drenching it in my own juices while I moaned my happiness into the room. And suddenly I felt it. That extra heat inside of me and while it should have scared me, in that moment it only threw me right into a second orgasm that made me arch my back and grasp my brother's body tightly as real spasms of pleasure washed over me.

 

[musicankane]

I didn't realized what she had meant by pulling out in time. In time for what? I should have asked her, but I was lost in the feeling of her soft slick walls wrapped so tightly around me. I became fancinated by how her body felt around my dick as I moved it in and out of her. I could feel her walls slick and wet sliding back and forth along my shaft as I moved in and out of her.

Her moans completely excited me, and I found myself wanting to fuck her harder to make her moan louder. I pumped into her as she began to orgasm beneath me. I felt her walls shiver and tremble around me, then she clamped down on me. My balls went ballistic and I lost all control of my orgasm. Feeling her cumming on me, made me explode.

I thrust deep into her and felt my cock spurting deep into her belly. I groaned as my orgasm rocked through me. The feel of cumming inside of a girl, to feel her slick wet walls holding my length while I rode the pleasure wave was wonderful.

When I finished filling my sister's womb with my stick swimmers, I slumped over her and smiled, "Wow that was amazing."

 

[Only_yours]

"Fuck yes it was.", I moaned happily as my brother fell on top of me, his penis slowly softening inside of me. For a good minute I just tried to catch my breath, processing what had just happened.
And suddenly it me.

"You came inside me, didnt you?", I asked, my voice betraying my panic. "Fuck...Im not on any kind of birth control."
I was terrified, cause our parents would surely kill me if I got pregnant without having a steady boyfriend. They would be even more shocked if they knew the father was my own brother.
While the scariest thoughts rushed through my head, there was also this small nagging voice in my head that kept reminding me how wonderful the sex and how amazing the feeling of him cumming inside of me had been. It had made me cum harder than I had in a long time and as I looked at my brother I wondered if I could really give up on sharing such an experience with him.

"Sorry....didnt mean to freak out. Its not your fault. I know that guys arent that good at holding off their orgasms and pulling out...", I told him in a calmer voice, giving him a tender hug. "Besides, it did feel amazing"

 

[musicankane]

At first we savored each other, smiling and enjoying the way it felt. My cock was spent and I felt myself softening inside of her...which caused her to flip out. She screamed at me about cumming inside of her and I didn't know what the problem was until she mentioned that I might have just knocked her up.

"Oh shit! Oh fuck! Sis i didn't know. I wasn't thinking right." I cried, now freaking out. I fucked my own sister and came inside of her. She might get pregnant because of me. I looked around for something to wipe my cum out of her, but I didn't think anything would work.

Then I remembered that she had one of those massaging showerheads in her tub and I said, "Quick Sis. Go wash it out." I told her pulling her toward the bathroom. "Use that powerful setting that makes you squeal and try to squirt my stuff out of you." I urged.
