The instant we finished our last assignment of the day -- a short worksheet on Native American migrations during the early colonial period, which we were allowed to work on together -- my sister took me by the hand and briskly led me out of the classroom. Our teacher had given us permission to leave early, as soon as we had completed the assignment.
We didn't bother packing up our books and bringing them back to our rooms for studying later on. There was no time for that. I was so eager to be back inside my twin sister that it almost felt like a physical ache coming from my crotch. I wondered if Julia was feeling the same thing.
"You can get your books later," Mom spoke loudly from behind her wide teacher's desk as we made our way out of the classroom. "And don't forget to grab a towel!" she yelled after us.
"Yes, Mom!" we called back in unison. We stopped by the downstairs bathroom to get an old towel. Apparently there was no time to travel up to Mom's bathroom for one of the nicer ones.

As I expected, Julia was leading us back to the living room. We stopped in front of the couch and my sister turned around and smiled excitedly at me.
My hand went up to her neck and drew her face to mine. I kissed her soft lips and she kissed me back, and we kissed again and again, and I was not aware of it but my right hand had wandered down from her neck to her left breast, and I fondled it in my fingers, and her nipple grew hard.
"Mm..." Julia moaned lightly as we made out. Soon I decided it was not enough to touch her outside of her clothes.
But before I could pull my sister's shirt off, she asked me: "Whaddaya wanna do first?" Her eyes were wide and red and she looked deeply into mine.
Remembering our lessons, I answered: "I should make you cum first, right?"
"I guess," Julia said disinterestedly. "Can I suck it first?" she asked, and I assumed she was talking about my penis, which was currently raging against the interior of my jeans.
"Sure," I swallowed, and she quickly went to her knees and began undoing my belt and my button and my zipper. She handled them so quickly that it was as if she did all three at once. In seconds my pants and boxers were at my ankles and I could feel my sister's warm breath against the underside of my penis, which was pointing straight up.
So I was right: she was talking about my penis.
"I just wanna..." Julia said thoughtfully to herself as she took the base of my shaft in her right hand and pointed the whole unit down towards her mouth. She flicked her tongue over the tip. As she drew away, a strand of precum connected her lip to my penis.
"There's already some coming out..." she said to herself after swallowing. Now she came back and slurped the head of my penis into her mouth. She began sucking, but only taking the head into her mouth, constantly dragging her lips over me, occasionally letting me fall out of her mouth so she could quickly swallow and then return to business.
It seemed to me that Julia was enjoying herself, and that she was doing this more to satisfy her own personal desires than she was to make me feel good. That made pretty good sense: I felt the same way about going down on her. It was cool that doing that felt good for her and would eventually make her cum, but honestly my biggest desire was just to taste her body and experience the texture of her delicious vagina against my tongue and in my mouth. The best part was when she finished. There was always so much fluid. It tasted so good.
I'm still so glad that she seems to feel exactly the same way towards me.

"Oh!" I heard Mom exclaim from the hallway. "I thought you guys would be in one of your bedrooms. You don't mind if I get started on dinner in here, do you?" she asked casually as she made her way into the kitchen.
Our living room and kitchen are right next to each other, with no barrier between them at all.
"I'm gonna start getting dinner ready. You kids all right with hamburgers?" Mom asked, crouched down with her back to us as she rummaged through the fridge for ingredients.
"Sounds great!" I said, not looking away from my sister's face, which contained most of my penis. For some reason, whenever she puts it in her mouth, I can't look away. It's just so amazing to see it disappear between her lips.
"MMmm-hmmmm!" Julia made an affirmative noise without taking me out of her mouth.
"All right, all right," Mom agreed. "I'm gonna put on a show while I work in here..." Mom picked up the TV remote from its usual resting place on the kitchen countertop. She opened Netflix and put on the Reba McEntyre sitcom show, but at a low volume. My sister and I tuned it out, and I suspected that Mom did as well, at least for the most part. There was something else going on that Mom seemed to be more interested in.
Julia began to work my shaft into her mouth, going down a little bit farther each time.
"Robert, did you make your sister cum yet?" Mom asked us as she was turning ground beef into hamburger shapes.
Julia let me fall out of her mouth and answered for me: "No, but that's okay, I just wanna suck Robert's penis," she explained before quickly stuffing me back into her mouth. Her tongue glided along the underside of my shaft.
"Honey, I think you should cum before you guys go very much further," Mom advised us from the kitchen. "You might regret it if your brother finishes before you do."
My sister rolled her eyes with my penis still in her mouth. "All right, let's do this real quick," she sighed, sounding disappointed that she had to stop sucking. I wanted her to continue, but I wanted to make her cum even more. I mean, don't get me wrong, I like orgazming myself -- it's mucho, mega fun, especially with my sister -- but for some strange reason, I wanted to make Julia cum even more. Is that weird? Is that selfish?
