I’d been planning this for years in an abstract sense, in a
theoretical sense, before I got my chance to make something really
happen. But when the opportunity presented itself, I grabbed it.

I’m 19 and my sister Sara is two years younger. I didn’t much notice
her beyond thinking she was an irritation until about two years ago.
One day she was this annoying girl, following me around, and the next
she was…something interesting. She didn’t have large breasts, but
they were perfectly shaped, and firm, and she had long legs that
wouldn’t quit. Both of us inherited the blue eyes and blond hair of
our mother, but a while back Sara started hanging out with a goth
crowd and she chopped hers off and dyed it black. I thought it was
stupid, but I have to admit it just makes her blue eyes all the more
intense, and that little attitude she’s got now just makes me wanna
smack her.

Our mom took off when we were kids and our Dad was raising us. He’s a
real bastard, and I was glad to take off for college last year. But I
was back for the summer, and of course Sara was still trapped here
with the hard-ass. Having an asshole for a dad made us closer as
kids, I think, but that kinda faded away when I became a teenager and
was too cool to hang with my little sister anymore.

The night in question Dad was off at some business thing and Sara was
off on a date. She’d lied to Dad about that, of course, saying she
was out with girlfriends, but I’d seen the douchebag with chains and
black clothes pick her up earlier. It was close to ten when I heard
his car pulling up into the driveway, but I didn’t hear the door
open. After a minute I walked over to the window, and saw them in the
car.

I figure Sara forgot I was home, or maybe she didn’t realize what a
great view into his front seat I had from my room. But my eyes
widened as I saw my little sister sucking this guy off in the front
seat. He was lying back with his eyes closed and she was really going
to town. I felt my own cock start to respond, but I didn’t touch it,
because as I watched a plan was forming in my mind. And for this plan
to come out the way I wanted, I needed to be good to go.

I watched as she finished him off–I could tell from his movements
when he came, and dammed if my little sister didn’t take it all. When
had she become such a slut? As they said goodnight, I left the window
and walked over to her room. I took a seat on her bed and tried to
make myself look casual.

A few minutes later she came into her room, unhooking her purse from
around her neck and throwing it on the floor. She caught sight of me
immediately. “Hey Mark, listen, I’m really tired, so I’ll catch you
tomorrow, okay?” I just stayed sitting there, looking at her face and
imagining again her sucking off that guy. It gave me a strange grin.

“Hey!” she said, louder. “Get out, okay? I’m tired.”

“No,” I said slowly. “I think I’ll stay.”

“What the fuck?” She looked at me oddly. “I said get out. I’m going
to bed.”

I rose off her bed and started walking towards the door like I was
leaving. “Okay,” I said. “I’ll just wait until Dad gets home and
tell him what you were doing with Todd. Or is he calling himself
‘Dark Raven’ or something these days?”

For a second she didn’t process what I’d said, and then I saw fear in
her eyes. Dad really was an asshole, and he was very strict with us,
but especially her. He certainly wasn’t above delivering an
ass-whupping if he knew she was going down on guys.

“Mark! You wouldn’t! C’mon, man, don’t be a dick. Don’t tell Dad.
Jesus. I can’t believe you were watching us! Pervert.”

I turned around and looked at her. She was wearing some sort of black
lipstick that had been slightly smeared by her earlier activities.
“Oh, I think I will. I think he’ll be very interested to hear what
his sweet little girl has been up to at night. Don’t you?”

“Please, don’t do that. You wouldn’t really do that, would you?” Her
voice was getting desperate–exactly as planned. “C’mon, I’ll do you
a favor too. I’ll do all your laundry this summer. Do you want me to
clean your room or something? You know I don’t have any money!”

“Well,” I said, and trailed off, like I was considering her offer.
She saw my resolve weakening and jumped in: “Please! Whatever you
want! Just don’t tell Dad.”

“Okay,” I said. “Here’s what I want. I want what Todd got.”

It took a few seconds for her face to react. I couldn’t believe I’d
actually said it, and clearly she couldn’t either, but I was trying
hard to stay calm. Here’s where it was going to go my way or all
break down.

“You want…what? Are you serious? That’s disgusting, Mark!” She
put up a good show of being indignant, but I could tell underneath she
was still mostly scared about Dad. Perfect.

“Okay,” I said, and started to leave the room again. “No problem.
I’ll just wait for Dad then.”

“No!” She yelled, and ran to shut the door before I could go through
it. “Lemme think for a minute! Jesus.”

I watched her face carefully as it flipped between mine and the
window. Her hand was unconsciously pulling at the hem of her short
black skirt. No nylons, I noted with approval. Just pale creamy
skin.

“Okay,” she said finally. “But you can’t tell ANYONE about this. Or
about Todd. And this is a one-time deal, get it?” I agreed
immediately. We could work on that one-time thing later.

Having agreed, it was clear she didn’t know how to start. This was
the part I’d practiced in my head, so I knew what I wanted to say.
But I was enjoying watching her discomfort. She paced the room a bit
and then turned to me, a confused look in her eyes.

“You can start by taking off your shirt,” I said kindly.

It looked like she wanted to react angrily, but she remembered what
would happen. So instead she said nothing and just pulled the tight
black top up over her head, messing her hair slightly. Underneath she
had on a lacy red bra. Where did she even buy that, I wondered? It
looked great, and I could see her nipples through the lace. I started
to feel the pressure of my cock pushing against my jeans as I imagined
what would happen next.

“That’s good,” I said. “Now, why don’t you sit on the bed?” She
moved over and sat down, and I walked over so I was standing just in
front of her. My eyes were completely stuck on her chest, and without
thinking I reached over and caressed one of her breasts.

“Mark!” she reacted without thinking.

“Yes?” I said. “Do you want to go back on the deal?”

She was clearly struggling, but after a minute she said no. I took
that as my cue and I reached behind her and unhooked her bra. Her
perfect breasts fell out, and I saw that her nipples were standing
straight out. I wasn’t sure if that was arousal or just the
temperature, but I decided to take it as a good sign. I took her
breasts in my hands and squeezed them slightly. “Not bad, sis,” I
said quietly.

I was dying to suck on them, but I was afraid of getting off-course.
I had plans to stick to. So instead I removed my hands and said as
authoritatively as I could, “Unzip me. You know what do to. I know
you do, I watched it earlier.”

Her hands came up to the top button on my jeans. At this point my
cock was so hard it was stretching out the front of my jeans, and she
had to hook her fingers underneath to get enough leverage to unbutton
them. She slowly undid the zipper and pulled down my pants. I was
wearing boxers, and she slid her fingers inside the sides of them and
pulled them down too, to expose my throbbing cock. I’d never been
this excited before. I was looking down at my little sister as her
face was just inches from my cock! She seemed to pause, so I said
quietly, “Go on. And do it right.”

With her right hand she grasped the base of my cock, and she slowly
moved her mouth to it. She glanced up at me one last time, with a
strange expression in her eyes–if I didn’t know better I would have
thought she was into this. Then she darted out her tongue and licked
up the shaft, back again, and up again, ending up teasing the head of
my cock. Finally she opened her mouth and swallowed the head of my
cock completely. It was the most divine feeling. I closed my eyes
for a second, but I had to open them again because I wanted to see
every second of this.

She started moving her hand up and down my shaft while she sucked and
licked the head of my cock. It was amazing and I had to try hard not
to come immediately. “Jesus, Sara, you’re good at this,” I heard
myself saying. She swirled her tongue around and brought her
other hand up to cup my balls. She started playing with my balls
while continuing to suck and jerk me. I couldn’t believe it–she was
really getting into it! And I found myself saying things I never
thought I’d have the chance to say.

“That’s right, sis. You like that, don’t you? You like sucking your
brother’s cock.”

She groaned and I felt her mouth go farther down my shaft.

“Take it,” I said. I felt like I was going to explode. “Suck on my
cock, you little bitch. You’re such a good little cock-sucker. Take
it down.”

A few minutes of this and I knew I wasn’t going to last that long.
But I had in mind something in particular for the end, so I grabbed
her head with my hands and pushed her down on my cock. I heard her
start to gag but I didn’t care. I felt my cock go all the way down
her throat and before she could pull off, I started face-fucking her.
I held her head with one hand and with the other I reached down and
grabbed her breast. I squeezed it while I plunged my cock over and
over again into her moist mouth. Jesus, she felt so good! I felt
myself start to get close. “Ready, sis?” I mumbled, although she
couldn’t respond with my cock down her throat. I pulled her head all
the way onto my cock and shot my load deep into her throat, and it
seemed to go on forever, spurt after spurt.

Finally it was over and I pulled out of her mouth. Before she could
try to spit I said, “Remember, just what Todd got.” She looked up
into my eyes and held my gaze while she swallowed it all. I couldn’t
believe my sister had just swallowed my come! The thought almost got
my cock stirring again, but I didn’t want to push my luck tonight.
That was for later.

“See you tomorrow night,” I said, as I walked out of her room.
