Chapter 4

It wasn't what I'd intended, but the thought jerked my dick a little. I was going to have to wash precum stains out of my pillowcase if it kept up like this. "Yeah," I said. If she refused, I still wouldn't have to show her. If she didn't… wow.

"I don't know about that."

Damn. I was more disappointed than I thought I'd be. "Well, or at least get all the way naked," I suggested.

She considered that briefly, then said, "Okay, but you have to take the pillow away first."

I hesitated one last time. "You're not going to tell anybody about this?"

"Oh, sure. I'm going to run out and tell everybody I watched my brother jack off while I stripped for him," she said with a roll of her eyes. Then she looked at me deadly serious. "You better not tell anyone either."

"I won't." I took a deep breath, and then pulled the pillow away. Free from resistance, it sprang forward, flopping down, fully erect. I held myself very still, bracing for possible humiliation.

Instead, she just looked at it for a few seconds, tilted her head, and said, "It's bigger than I thought it would be." I let out a breath I hadn't realized I'd been holding. Without waiting any more, she pulled her top completely over her head, and then started to unbutton her jeans. Her ass looked good in a pair of jeans, but even better in just a pair of purple and green panties that clung tightly to her. My eyes fixed on her crotch, waiting to see if they'd drop next, not really believing they would. "So are you going to start doing it, or what?"

It was as though I was hypnotized. Still staring at her, my hand slowly moved towards my cock of its own accord, and I began to rub up and down, slowly at first.

Once I'd begun, she pulled the panties down, all the way, and I saw her pussy, at the bottom tip of another tan line triangle. She was shaved bare, and her mound was beautiful jutting outwards just a little. The slit itself looked incredibly tight, with a ribbon of pink flesh in between the lips that separated into two ribbons towards the bottom. "I'm keeping my socks on, 'cause the floor's kind of cold," she said.

I didn't really pay what she was saying much mind. "Yeah, sure, whatever." I was stroking there, eyes moving back and forth between her pussy and her breasts. I tried not to look at her face, but whenever I looked up from her pussy and caught a glimpse of her watching my dick it ramped up the excitement. A naked girl in my room was hot. That it was my sister was incredibly dirty, somehow beating out even the raunchiest porn.

After a minute or two of just standing there in front of me, Krista looked around and got my computer chair, wheeled it across the floor a little, and sat in it, spreading her legs so I could get a good look. "Hey, Bobby… what do you think about when you do it?"

"I don't know," I said. "Girls I like. Sex stuff I want to do."

"Have you ever done it? Sex?"

I thought about lying, but I just assumed she'd call me on it. I wasn't exactly a social butterfly and she knew it. "No, but don't tell anybody."

Krista leaned back in the chair and one hand crossed over her pussy. One finger ran down the slit, separating the lips just a little as it went. "So what's the furthest you've gotten?"

"Kissing a couple girls. And I felt up Judy Austen a little." She broke it off soon after. That had ramped up my anxieties; she wouldn't tell me why, so I'd naturally assumed I'd done it wrong. "How about you?" For some reason, I didn't think my sister was still a virgin. She was too hot, and had a couple boyfriends, though she wasn't seeing anybody right now.

"You can't tell Mom or Dad, right?" I agreed quickly. "I've given a couple guys I dated blowjobs. I haven't actually done it all the way yet, though I came close with Tommy." Her last boyfriend. They broke up after she caught him kissing her best friend. I only found out about it through Facebook, a couple days after. To cheer her up, I sent a message where I offered to beat the crap out of him. I got a smiley face response and a thanks, but she told me no, which was a huge relief… I didn't think I could take him. "I'll probably give it up to the next guy, I think I'm ready. I'm already on birth control."

I chuckled nervously. "I suppose the brotherly thing to do would be to tell you to wait, but the truth is if it was up to me, I'd have lost mine years ago."

She smiled. "You're not a bad looking guy. You probably would have lost it if you were just more confident. A couple of my friends have had crushes on you. They still might."

My eyes widened. "Really? Who?"

"Nuh-uh. I was sworn to secrecy. Besides, you have to learn to ask out girls who you don't already know are going to say yes." That was how it was with Judy, and Krista knew it. The only thing that convinced me to ask her out was because a friend of mine swore she liked me and had been asking him about me. Even then I had to send a message to Krista to make sure that there was no other possible reason she'd be asking my friends questions about me before I had the courage to approach her. The couple other girls I'd kissed had all made the first move. Objectively speaking, that even one had done so suggested that I was good looking, but somehow when I looked in the mirror I never saw what they did, so the anxieties continued.

For a while as I pumped up and down on my dick, I wondered which of her friends might like me, but that thought fled as I noticed her dipping her fingers into her hole, sliding them inside and withdrawing them slick. It wasn't a one-time motion, she repeated it over and over again. Her thumb would, every so often, make a circular motion, pressing in, not on the clit itself, but on the flesh immediately above it. She was starting to breath differently too, like she was holding her breath for short bursts and then releasing it all at once. Seeing my sister masturbate so openly made me pick up my pace as well.

"So, do you think I'm hot?" she asked suddenly. "I mean, forgetting that you're my brother. Just pretend you're some guy and we don't know each other."

"Yeah," I said. It was getting hard to speak and maintain focus. I was no longer urging an orgasm on; I was trying to hold it back. "You're gorgeous. I mean, I always knew you were pretty, but with that body, wow." I smiled weakly. "If you weren't my sister I'd…"

I'd trailed off, so she prompted. "What?"

"Anything you'd let me," I said. Unfortunately that was the way it always was with girls. Sexually speaking, a guy would be willing to do anything a girl would let him. Didn't my sister know that? "Fuck, I'd eat you out for an hour, even if all I got out of it was a close up look."

Her legs moved closer together, squeezing slightly. "Ha," she said. "As if." Her fingers quickened. I guess she was starting to get into it. Maybe I'd even see her cum.

That thought pushed me over the edge. My dick felt like it suddenly stiffened one last bit, even thickened, and no longer did it depend on my motion to give it pleasure, it felt incredible with no motion at all. Pressure rose up from the bottom of my shaft. My sister said something, just the word, "So…", but I couldn't pay her any attention. Before my mind blacked out entirely for its moment of bliss, I reached over to hurriedly grab some tissues, put them in position.

I didn't moan or grunt, just shook a little as the first jet burst up and out of me, landing in the Kleenex while I was overcome with a more intense orgasm than I'd ever felt before. A second and third jet followed, not quite as pleasurable, but still better than the average first cum. After that, there would be a few more waves as the rest of my cum made its way out over the next thirty seconds or so. There seemed to be a lot of it this time, but then I'd been saving up.

"I guess you're done," Krista said. It was funny, she sounded almost disappointed.

"Yeah," I said. Once again uncertain and awkward, I began said wiping out even the excess dew from the head of my penis, just for something to do. "Thanks."

"So I should go?"

"Probably," I said, though I wanted to watch her cum too. I hoped she'd offer that, but she didn't. She took her hand off her pussy and stood up, then got her clothes. She put her shirt on first, then panties, and finally her jeans. Then, without looking back, she left the room. A few seconds later, I heard the door to her room close. I came out of my room a few minutes later, dressed, to go to the bathroom and flush my tissues down the toilet, stopped briefly at her door, but moved on.

I'd wanted to talk to her about what we'd just done, but now that I was no longer outrageously horny, it just didn't seem conceivable to knock, go inside, and bring up some kind of sexual conversation with my own sister. If we'd still had our cell phones I might have managed to text her to get a conversation started without the awkwardness, but while we were disconnected I didn't know how to bridge the gap. So I just let it lie, hoping she'd just come to the obvious conclusion that this was a one-time thing and we wouldn't repeat it. We probably wouldn't even speak of it. That was okay.

There was some dark part of me that wanted to repeat it, wanted to go even farther, but I was certain that would be impossible. So just burying the event, denying it had ever happened became the next best choice.

Pretty soon Mom and Dad came home, and started making dinner. Once again we were pressed to 'connect' by telling stories about our day. Well, one big thing had happened to me today, but there was no way I was talking about it, and luckily neither was Krista. We did exchange one brief look and awkward smile when Mom first asked, but then Krista launched into a story involving one of her friends.

I thought about masturbating that night in bed. Krista already knew I did it and had seen me do it… but I suppose I still had the worry that my parents could hear, so I held off and just drifted off with an erection, remembering the sight of my sister's pussy
