My sister and I were both very eager for school to start the next day.
"Do you think Mom's alarm went off?" Julia asked unsurely, kicking her feet at the ankles.
We were sitting on the couch in the living room, starting school in the living room per our teacher's instructions from the previous day. And naturally, since we're siblings and all, we were sitting close enough that our thighs and knees were touching. I casually observed my sister's outfit: jean shorts and a shirt that was, as usual, loose enough so as to not give away the true size of her surprisingly large breasts. It was about 8:55 in the morning. We weren't usually early for class, but lately...
"I guess I'll go check if we don't hear anything in the next few minutes," I said as I laid back on the couch. We were downstairs, with Mom's bedroom almost directly above us. We would be able to hear any movement from above us. So far, there had been nothing.
My sister stayed seated, hunched over and looking impatient to get started with the day's lessons. I reached up and scratched her back, my fingernails gently running up the sides of her spine, just the way she liked it. She shuddered, arched her back forward and pulled up her shirt to expose her bare back, a years-old sign to keep going. I did. She let out a sound of satisfaction that was almost too faint to hear.
By the way, this sort of contact wasn't unusual for me and my sister at all. I mentioned that we were twins, right? We scratch each other's backs all the time. And since we're almost genetically identical, we know exactly what feels best for each other.
As I scratched, I observed some of my sister's side boob, the nipple not visible due to the angle. I had never realized, until recently, how beautiful my sister's body was. It was hard to describe how I felt when I thought about or looked at her now. But as I observed that side boob, there was an obvious change in my groinular region. A growing change. Mysterious and wonderful.
"I hope we hear something soon," Julia said. Just then, we heard some movement from upstairs and soon after the sound of the upstairs shower rattled in the wall.
"Thank GAWD," Julia said, rolling her eyes impatiently.

"Sorry, class, sorry I'm laaate," Mom sang as she entered the room, fully decked out in one of her favorite teacher outfits: a nicely fitting teal pants suit. It didn't show any cleavage: our mother was always professional during school hours. She was carrying two large fluffy towels from her bathroom, and she set them down on the large chest of drawers in front of the living room TV.
I was still leaned back on the couch, scratching my sister's back with her shirt partially pulled up. When Mom, our teacher, entered the room, we sat up straight and Julia let her shirt fall back down. School was in session now, and we would follow our teacher's lead for the rest of the day.
Mom clasped her hands in front of her with a light slap of her palms. "Okay! I thought for today, maybe you two might want to decide how we get started? Julia, any ideas?" Mom suggested to my sister.
Julia thought for a moment. "I wanna make Robert cum again," she said confidently, looking over at me with a little smile. I think I grinned back at her.
"Okay. Okay, that's good," Mom said. She looked around thoughtfully for just a moment. "But actually, it would be best for your brother to make you cum first. Do you know why?" We both shook our heads, but I thought I had an idea. It turned out I was basically right:
"Well, guys, when a man has an orgasm, he kind of... well, he 'finishes' in a way. His penis might not get hard again right after, and he'll also become less interested in sex, just temporarily." She paused for a moment. "This is less of a problem for young people," she added. "But regardless, it's generally best for the man to orgasm last. It's usually the last thing that happens during sex," Mom explained clinically.
"Oh! That makes sense," Julia agreed. "Sooo...?" she began to very slowly unbutton her pants, looking back and forth between me and Mom.
"Julia, let's have your brother undress you. It's good practice. Stand up, honey," Mom instructed.
My sister stood up and faced me. She lifted her shirt and began to slowly and rhythmically gyrate her hips in a circular motion. The movement was so slow and so slight that I do not think she was doing it consciously. She was lightly humming a cute little "waiting" song - I do not think she was doing that consciously either.
I sat up and began fumbling at the metallic button of my sister's pants. Her skin was so very soft on the backs of my fingers and hands. I had never unbuttoned anyone's pants but my own, so it took a moment, but I got it done. Then I unzipped. A moment later I had my sister's pants and underwear around her ankles, and I helped her step out of them.
Julia still held her shirt up. I gazed ahead at my sister's vagina, still nearly bare from the trim job she had done before. She stepped closer to me. I breathed in deeply through my nose. She smelled so wonderful. I was fully entranced and well on my way to being Stone Cold Steve Austin (I'm talking about my penis, people!).
"Her shirt, too," Mom reminded me.
Now I stood up too. I took my sister's shirt by the hem. She held her arms up, and I pulled her shirt up and over her head, tossing it to the couch behind me. She stood in front of me, completely naked, smiling so wide that her eyes were almost shut.

I had never kissed anyone before, at least not in the way that I kissed Julia then. I didn't think about what I was doing, and I wasn't even aware that it was happening until after.
I know it seems really weird, getting my first blowjob and going down on a girl before even getting my first kiss, but that's just the way it went down for me.
Even though we didn't kiss for very long, and we didn't use our tongues, somehow our first kiss felt even more strange and wonderful than anything we had done in the previous two days of sex ed. We must have disconnected and reconnected our lips to each other's a dozen or more times before Mom interrupted:
"Julia, would you like to undress your brother now?" Mom asked while we were still making out.
Our lips disconnected after a final kiss. I slowly opened my eyes and looked into my sister's perfect face. She looked deeply into my eyes and nodded slowly in reply to our teacher.
Julia's hands reached for the hem of my shirt. I lifted my arms as she pulled it over my head and tossed it to the floor. I kissed her again once I was shirtless. She kissed me back and didn't stop.
"His pants, too..." Mom reminded my sister. She sighed, dropped to her knees and began fumbling at the button of my pants.
I was quite erect by this point. Once my sister pulled the waistband of my pants far enough down to release my penis, it shot back up and almost hit her on the nose.
"Whoa!" Julia exclaimed. "It's already hard!"
"I don't think it's quite all the way hard yet, honey," Mom said, stepping closer to us and looking curiously and closely at my penis. She was right; it was probably at about the three-quarters mark right then.
"Why's it so hard already?" Julia asked us both. "It's just, on the first day, it took a while? Right?" she said unsurely.
