Siblings Who Lust With Trust

I shook my head. No. This would be ten kinds of wrong. Not only was he my little brother, but he was only just barely twelve. I hadn't lost my virginity until I was… well sure I'd been twelve, too, but more twelve than he was.

Still… while there were a dozen or so good reasons not to do it with him, were there any good reasons to do it with him? It would be a present I wouldn't have to pay for, which was good. It'd certainly make him happy, which was good. Plus, well, I hadn't been laid in a few months. Getting fucked again would be nice, even if it was with my little brother. Even better, I wouldn't have to make him wear a condom, cause it would be his first time.

Since I was on the Pill, pregnancy wouldn't be an issue.

I tried to fight back on the thoughts even as my hand drifted down between my legs. No, no, no. I couldn't have sex with my little brother. That would be just bad as bad can be. I mean, there was no way it could be a good idea.

But maybe… well… maybe…

I sat up. I couldn't let him fuck me, but I could at least do a few other things with him, couldn't I? Just so that he would learn a few things, maybe get off, certainly have a better birthday than he had so far.

A little tingle went through my vagina as I turned the light back on and grabbed my bathrobe. Yes. I'd do a little bit of stuff with him. Just enough to give him an education about sex, but not enough to actually get fucked by him. That'd work.

Before I could chicken out, I went into the hall and knocked on Jonathan's bedroom door. His light was still on, so I was pretty sure he was awake, and I hadn't heard the bedsprings, so I guess he was done with that.

“What?” came his voice.

“Let me in for a second.”

“Okay.” He came up and unlocked his bedroom door. As he opened it, I saw he was wearing only a t-shirt and boxers. Good. “What?”

“I have a birthday present for you,” I said with a smile.

“Oh?” Jonathan perked up a little. “What is it?”

“Sit on your bed and close your eyes.”

He did so.

I took a breath. This was it. I unwrapped my robe and let it drop to the ground.

Then I softly said, “Now open your eyes.”

Jonathan did so, and then opened his eyes even wider as he looked at my nude body. His mouth opened and he squeaked out, “You're naked!”

“Yes,” I replied, “ I know.”

“Why are you naked!?”

I sat down on his bed as he moved away a little. “I'm naked cause I'm going to give you a present. I'm going to teach you all about girls.”

“You are?”

“Yes.”

“Oh.”

I sat back on my brother's bed and spread my legs, grateful that I kept my pubic hair to a minimum.

“Anything you wanna know?”

“Uh… god… I don't know…” He looked at my naked body. “I mean… this is all… you know… like a surprise.”

“Aren't birthday presents supposed to be?” I smiled like a she-devil.

Jonathan grinned back. “Yeah.”

“So?”

He looked at me some more. “I just don't know what I should ask about.”

“Ask anything.”

“Well… well… where does the boy… you know… stick it in?” Jonathan asked with a blush.

“That's easy. Right here.” I reached down and spread my vagina open with my fingers, giving my brother a good look.

“Oh! Wow…” He peered down. “Cool.”

“You can stick your finger in there, if you want,” I said, already prepared to at least go that far.

“Wow, really?”

“Yeah. Just lick it so that it's wet and slide it right inside.”

Nervously, Jonathan liked his index finger. It shook slightly as he moved it down between my legs. I closed my eyes in anticipation and then felt the sensation of his finger slowly sliding down into my wet vagina. I let out a little sigh of pleasure and opened my eyes as I pulled my fingers away.

“See?” I said.

“Yeah… wow…”

I felt him wiggling his finger around inside me. It was very nice. I grinned at him. “That feels good.”

“It does?”

“Yeah.” Looking down I could see the tent in Jonathan's boxers. “Why don't you get out of your clothes, too?”

Jonathan looked at himself. “Me?”

“Yes.”

He licked his lips as he thought for a moment, then nodded and pulled off first his t-shirt then his boxers, letting his virgin penis pop into view. It was still totally hairless and probably only about four inches long. Looked nice, though.

“You can touch my breasts, too, if you want,” I told my little brother.

Jonathan reached over and tentatively rested one of his hands on one of my breasts. He rubbed at it a little. “Feels neat.”

“I bet it does,” I said with a smile.

Jonathan blushed. “I liked it better when I had my finger in you, though.”

I laughed. “So did I! You can put it back in if you want to.”

My brother crouched between my legs and slid his finger back into my vagina.

I let out another happy sigh. I'm sure he was enjoying his birthday present, but I was certainly not minding it much myself! The boy had no real experience, but he was a quick learner and had good instincts.

And then I gave in to what I really wanted. “Jonathan?” I said to him.

“Yeah?” he said back.

“Get on top of me.”

Jonathan blinked. “On top?” he asked weakly.

“Yes.”

Swallowing visibly, Jonathan moved his lean, naked body between my spread legs. As he settled on top of me I felt the tip of his penis brush lightly against my vagina. He looked at me with an expression of tension and desire on his face.

“Now what?” he whispered.

“What do you think?”

I felt him shaking a little as he whispered, “Am I going to…” He trailed off.

“Say it,”

I demanded.

Jonathan took a deep breath and shifted his weight a little, sliding his penis against my clitoris. “Am I going to… to fuck you?”

“Do you want to?” I asked, reaching between our naked bodies to take my little brother's penis in my hand, stroking it slowly. Still slightly unable to believe I was actually doing this, but happy I was able to make my brother feel good for his birthday, I put him into position and pushed down on his cute little butt, feeling his twelve-year-old virgin penis slowly slide into my tight, wet, fifteen-year-old cunt.

“Oh, god,” he whispered as he sank into me. “I can't… I can't believe I'm… really inside you…”
