Chapter 6

"Sure," I said. She unclamped her legs and I reluctantly withdrew my fingers and slid a little away from her. "What exactly did you have in mind?"

"A blowjob."

"Oh, come on," I said, unable to believe it. "I know you know how to give a blowjob, you said so." Inside, a tiny voice was screaming at me, "You idiot! If someone offers to practice giving you a blowjob, you say yes! You don't question, you just agree!" But somehow that voice hadn't stopped me.

Luckily, my sister didn't take offense. She spoke rapidly, looking down at her hands. "It's just… when I did it with Tommy I never made him cum. I could suck on him for an hour and he wouldn't squirt. But if I pulled out and used my hand he went almost right away. Blowjobs are supposed to be better than hand jobs, right?"

"From what I hear."

"So I'm worried I was doing something wrong."

"Maybe he's just secretly gay."

She laughed a little at that. "No, Tommy was definitely not gay."

"Well, I can't think of any other reason. I mean, you're not biting or anything are you?"

"No, of course not!" she cried indignantly. "So are you going to let me do this or not?"

"Of course." She looked at me, down at my pants, and it took me a second to realize that a blowjob would be much easier to accomplish if I had my dick out. I unzipped my pants and pulled them down, then looked about awkwardly. "How should we do this? Lying down? Sitting down?"

"You can stay where you are," she said, and got off the bed to kneel at my feet. My dick was pointed towards her. I could hardly believe it was happening.

My sister looked up at me. "Okay. Be honest. If I'm doing something wrong, don't hold back 'cause you're my brother, okay?" I nodded. I hoped she hadn't noticed the way my dick stiffened and jerked when she said the words "you're my brother."

With one hand, she grabbed onto my shaft, then leaned in and started licking the head. Certainly no complaints there, it felt amazing. She moved her head around the side of it, putting a tiny bit of pressure on it with her lips, lightly nipping at it almost, though without teeth, before she returned to licking dead center. I felt Krista's tongue stop right beneath my head, stuck all the way out, and then she suddenly bobbed her head forward, mouth open, and took me inside.

She sucked on the just the head for a little while, then went down as far as she could before she ran into her own hand, which was still squeezing the base of my dick. It was thrilling, stimulating, perfect. I had no standard of comparison save my hand, but I couldn't see anything wrong with her technique. I reflexively gripped the edge of my bed. "Oh, wow."

She pulled back to just the head and curled up her lip in the cutest smile, and then went down again. Pretty soon she was pumping back and forth in a regular rhythm, and as I watched her head bob up and down, cheeks sunken in very slightly, I thought about how wrong what we were doing was. But not with guilt or fear, the wrongness itself was turning me on. I thought about all sorts of other wrong things to do, fucking her, cumming inside her, even getting her pregnant.

I almost spurted right then and there, but didn't want my sister to think I didn't have stamina, so I forced my mind to other things: schoolwork, baseball, what might be happening on my favorite TV shows, whether my sister might tell somebody, the shame and dirty looks and laughter behind my back if anybody did. That last one was too far in the other direction.

"I knew it," she said, pulling off. "I knew I was doing something wrong."

"What?"

"You got soft."

"No, it wasn't you…"

"I told you I wanted you to be honest."

"I was," I insisted. "It wasn't you, you were doing great, it was just a thought that crossed my mind."

"What?"

I figured I'd be honest. "What sort of shit might happen if you told anybody about this."

"Relax. Nobody's going to find out, I promise." She waved my dick from side to side. Still only semi-erect, it flopped a little. "So think of something hot so I can finish?"

I did, I thought once again of fucking her, in my bed, in her bed, in the bathroom, in our parents bed, in every position imaginable. I imagined cumming all over her and then inside her. It was good enough, my cock stiffened with renewed vigor and jerked with the impossible hope that the fantasies might someday come true.

Krista went back to sucking on me, and, as though she doubted my word that she wasn't doing something wrong, put even more effort on it, her tongue, inside of her mouth, slid around me. A couple more minutes of that was all I could take. My balls felt like they were coming to life, ready to go into production, and I was starting to feel that extra stiff sensation in my dick. I figured I should warn her. "Okay, I'm about to cum." I tried to reach for my tissues with one hand, but they were a little too far. If she pulled off it might be a big mess.

Luckily, that didn't happen. She just made a "Mmhmmm" sound to show she heard, but kept right on sucking. When I was just about to blow she retreated so that her mouth was on the head of my dick, and her cheeks collapsed again. A wave of pleasure rushed through me, making most of my muscles tense in anticipation of feeling it, and then a jet squirted out of me and into her mouth. I couldn't see it, but I knew that's what happened.

And my sister swallowed. Six or seven jets went out of me and down her throat. When I was down to a dribble, she pulled off and let me go. "So, I guess it was good?"

"Yeah." I took a deep breath, then another. "I think there's only one explanation for why Tommy didn't cum." She looked up at me, eyebrow cocked. "He's definitely a fag in denial. No straight man wouldn't cum from that."

She giggled a little. "Trust me, he's not gay."

"You said you never went all the way with him, right?" I said. "That proves it. Even if by some miracle he didn't cum from that blowjob, it would only be because he wanted to fuck you. Any straight guy would do everything possible to fuck you."

She smiled, then teased, "You're a straight guy, aren't you, Bobby? What exactly are you saying?"

My smile was uneasy, because the tease was too close to the truth. "Well, any straight guy who's not related to you." And even then…. No, it was best to get off the subject. I was pushing my luck as it was.

"So what was it that got you hard, then, after we had to stop for a sec? Since you weren't thinking about me?"

I blushed a little, turned away. "I don't know, I guess I was just thinking of pussy." Then I decided to go a step farther, somehow I didn't fear her judging me as much, "I guess it probably looked a lot like yours. But only because it was the closest real one I've seen."

"It's not that mysterious, you know," she said. "It's just a crack. It's not the kind of thing where a guy would…" she stopped suddenly, and laughed, before continuing, "lick it for an hour just to get a closer look."

I blushed a little more, remembering I'd used similar words. "Some guys would. I would, but maybe not just for the look."

"What for then?"

"To make the girl feel good. That's an important skill to have. And it's something else I need practice in
