"Don't swear at me, Tommy. Don't you ever swear at me."
"Wasn't swearing at you, Elly. Just swearing."
"Well, don't. Swearing doesn't help."
I did a stupid thing then. I mean I said something stupid. I said, "I've heard you use words that were worse than swearing."
I was getting more and more desperate and all this talk didn't help much. "Elly," I said, my speech suddenly thick. "Touch me, will you?"
She flopped on her side again with her face turned away from mine. "Touch you… where, Tommy?"
"You know," I said, gulping.
"I don't want to do that, Tommy I'm your… sister."
"What difference does that make?" I said, fiercely. "Nobody here but us. Who's gonna know but you and me?"
She was silent again for a moment. Then: "Tommy, do you know what adults call this?"
"No, what?" I knew, but I wanted to hear her say it, if she really knew and wasn't just girl-faking. Girl-faking is when a girl pretends she knows a lot more about something than a guy but really doesn't.
"They call it incest, Tommy."
"I don't care," I said roughly, the word having shook me quite a bit. "I don't care what they call it."
She moved her body slightly so that her buttocks brushed against my agonized dingus. "Did you like that, Tommy?" she asked softly.
I sucked in air like crazy. "Yes. Do it again, Elly."
"No," she said. "I'm not gonna do it again."
"Elly… can I?"
"Can you what?"
"You know, damn it."
"I told you not to swear at me."
"Nuts," I said. "Nuts."
"You can, Tommy," she said quietly. "But if you ever tell anyone, I'll… brain you."
"You mean it?" I asked, my heart caught in my throat now. It seemed to be, at least. "Do you really mean that, stupid?"
I rammed my peter between her legs suddenly, but she jumped away and flipped over on her back, her eyes angry. "That's not the way!" she cried. "What's the matter with you?"
I was bewildered. "What do you mean, Elly?" I stammered.
"You have to make a girl hot first, silly. Play with me."
"You mean play with your…"
"Play with my titties, Tommy. Haven't you ever been out with a girl?"
"Course I have," I retorted. "What do you think I am – a stupe? How was I to know you wanted me to play with your titties?"
"You always play with a girl's titties, Tommy. Always."
She was looking at me now and I didn't want her to. "Turn over on your side again," I said softly, my small amount of resentment having left me. "I'll play with your old titties if that's what you want."
She glared at me. "Well… you don't have to, you know. If you wanna go back to your own bed, go ahead."
I had gone too far. I pulled back immediately. "I'm sorry, Elly. It's just that when a guy gets hot like I am he… he doesn't know… he doesn't know what he's doing."
She giggled again. "Sure. I know. Only… play with me for a while. Gee, I want some fun out of it, too, you know."
"You do?" I asked, my heart hammering furiously again. It was wildly exciting to hear a girl say that.
"Course I do. What's the matter with you, anyway? Do you think I'm dead just because I'm a girl?"
"I just never thought…" I had to break off the sentence because I wasn't sure of what I had been about to say.
"Why don't you play with me, stupid?"
I didn't much care for this. "Wish you wouldn't call me that. I don't call you names."
"Okay, Tommy. I'm sorry."
I put my hand on her titty and she sighed. "You like that, don't you?" I asked, my voice sounding hollow.
"Yes. It makes goose bumps all over me. Rub the nipple, Tommy, rub it gently. Make me real hot like you are."
I rubbed her nipple gently and she thrust her hand in back of her and I felt her fingers going around my cock, felt her running her hand up and down on it. I squirted a little on her butt and she giggled nervously.
"You hit me," she said. "You hit me with your stuff, Tommy."
I was breathing hard now. "Yeah," I said hoarsely. "Man, am I ever hot."
"Rub my titties harder now, Tommy. Then you can stick it in."
"All right," I said, my voice sounding as if it came from a mile off. I rubbed her titties hard, making circling motions, and she cried out once or twice and squirmed about a lot on the bed. "You really love that, Elly, don't you?"
"Take your pajama pants off, Tommy. I'll take off my nightie and put it under me."
"What for? Why put your nighties under you?"
"So Mom won't know, stupid. Supposing you squirt all over the sheet?" She sat up and yanked her nightie over her head and placed it under her butt.
"Won't Mom see it if I get it on your nightie?" I asked.
"I can wash my nightie and she won't think anything of it, but if I washed the sheet she might wonder about it I never wash my sheets but often do my nightie."
I grinned nervously. "You got everything figured out, haven't you… and all the time I was scared of what you'd do… if I crawled in bed with you."
She giggled. "Well… you really shouldn't be here, Tommy. After all, you're my brother."
"Guess we're pretty awful, huh?"
"Not if we keep it to ourselves. Lots of girls do… it with their brothers, Tommy."
"I never heard any guys say that."
"Maybe guys don't want to tell other guys, Tommy."
"Maybe. You mean girls tell each other?"
"Some do."
"You got me worried now. How do I know you won't tell some of your friends?"
"Don't worry. I won't tell anybody. These girls who tell this are just plain nuts. I'm not."
"Okay," I said, reassured.
"Take off your pajamas. You'll get stuff on them, too, maybe."
I kicked off my pajama bottoms and pushed them off to the floor. Man, it felt great to have my lower body bare and up against her bare body. Her body was warm and soft and wildly exciting. I nearly blew there and then without even touching her, not really.
"Rub 'em, Tommy. Just a little while longer."
I rubbed her titties until I couldn't stand it any longer and then I pulled her legs apart and tried to crawl on top of her.
"Hold it," she said. "Not yet. I'm not ready."
"How long does it take you to get ready?" I asked, annoyed at her.
"I'm a girl. Give me time."
"You've already had lots of time. Come on let me put it in."
"Boy, I never saw anyone like you, Tommy. I think you're just mean and selfish."
"I am not," I retorted. "I'm just hot."
She sighed and lay flat on her back and looked up at me. "All right, Tommy. Put it in me. Be careful. Don't just ram it in. Put it in nice."
It was the way she said it, or maybe the fact that she said it, but it caused me to squirt all over her tummy. I started to say I was sorry – I was a bit confused – but she just giggled and told me it was nice. I grinned and lay down on her partially and fumbled around trying to get the head into her cunt. She moved each time I poked at her and this made me kind of annoyed.
"Hold still, damnit," I said. "What do you think I am – a magician?"
"Don't swear, Tommy," she cautioned. "I was just teasing you."
"Well, don't tease me. I can't stand it. First thing you know I'm gonna pop it all out on your tummy."
"I wouldn't mind," she said, sighing. "Boy, that felt good, all hot and sticky and stuff."
I grinned again and poked it at her cunt. This time she spread her legs wide and helped me steer it in. I almost went nuts when I felt my hard-on entering her wet cunt. Man, it felt good. It was so warm and slippery and… well, great.
"Now don't go off right away, Tommy," she said. "Go slow and let me have my fun, too."
I moved as slowly in her as I could stand doing. Then I began to speed it up a bit.
"Tommy, keep it slow. You can go faster later when you're ready to blow."
"I'm ready to blow right now," I groaned. "Let me go fast. I can do it to you three or four times."
