Title: Built-in Friend
Summary: A preteen girl discovers that having a twin brother is more fun than she had previously thought.
Keywords: bg, inc, 1st

Having a twin is like having a built-in best friend. That's what they 
say. I don't know who "they" are, but I bet they aren't twins.

Don't get me wrong, my twin and I get along just fine--better than most 
siblings, if I can believe my friends' complaints about their brothers 
and sisters. It's just that I'd never thought our relationship was 
anything special or unusual.

Maybe it's because my twin's a boy, and I'm a girl. Of course, we're 
not identical twins, but we do look a lot alike, except that my hair's 
longer than his (though, not by much), and he has those dangly bits 
between his legs.

I know, "Ew!" But out of convenience, our parents have bathed us 
together since we were babies, and we only just stopped taking baths 
with each other about a year ago because I need extra time to make 
myself presentable, while my brother almost has to be forced to bath 
regularly. Besides, I know other brothers and sisters who bathed with 
each other until they were like six or seven, so ten's not that weird.

Let's face it: Brothers and sisters are bound to see each other naked, 
now and then. It's hard not to when you live in the same house and have 
to share a bathroom. Maybe being the same age makes a difference, but 
my brother and I are totally blase with seeing each other all nakey.

Maybe, sometimes, we're a little too casual, like when he walks naked 
from our bathroom to his bedroom when my girl friends sleep over with 
me, or when I'm sunbathing nude in our backyard when his friends come 
over to swim in our pool with him, but that's beside the point. Like, 
what eleven-year-old doesn't already know about the differences between 
boys and girls? Get real!

Yeah, and we sometimes share the same bed, but again, it's like a 
convenience thing--when we're staying over with relatives or on 
vacation and staying in a hotel, or something--but we sometimes sleep 
in our parents' bed, too, for the same reasons. It's not that unusual, 
and it's certainly not weird, although my friends get all freaked out, 
if I ever mention it.

So, like I was saying, my brother and I get along with each other just 
fine, but there's nothing special about our "relationship." That is, 
there wasn't anything special about it until I caught him peeking at 
me. 

I was totally surprised because, like I already told you, he's seen me 
naked for eleven years, but ever since my boobs started coming in, I've 
caught him staring at me. It's really funny because he's so totally 
obvious, but he pretends like he's not doing anything. 

I mean, I don't have anything but a couple of bumps, right now, but 
he's totally obsessed with them. A few of my friends who are a little 
more developed than I am say that their brothers act the same way, so I 
probably shouldn't have been bothered, but I was starting to get a 
little creeped out with it.

I'd come out of the bathroom, and my brother would have his door 
cracked open a few inches. I suppose he thought that he would be able 
to see me without me seeing him. You'd think he'd be smart enough to 
figure out that it works both ways. Boys can be really dumb, sometimes.

Anyway, one night, I got tired of putting on a free show for him, so I 
flung open his door, struck an alluring pose, and said, in my snippiest 
voice, "Why don't you take a picture? It'll last longer."

I guess I expected him to pretend like he didn't know what I was 
talking about or come up with some lame excuse, but  I didn't expect 
for him to actually reach for his digital camera. Boys!

I quickly moved towards him, shoving my hand forward to block his shot. 
He tried to dodge me, and I ended up grabbing both his wrists and 
wrestling him onto his bed. (I don't care what "they" say about boys 
and girls, I'm stronger than my brother--and faster, too.) With my 
knees pinning his shoulders down, I had no problem snatching his camera 
away from him.

"What do you think you're doing, dork brain?"

"You told me to take a picture!"

"I was being sarcastic, doofus! Why do you always have to be staring at 
me, anyway?"

"I wasn't!"

I gave him a look that told him, "I'm not buying that one!" He gave me 
a sheepish grin.

"Okay, so I was staring at you. What's the big deal?"

"It's starting to creep me out, that's the big deal. Stop it! Why the 
sudden fascination? It's not like you've never seen me naked, before."

"Yeah, but you're starting to grow breasts. You didn't have those, 
before."

"So? You've never seen breasts, before?"

"I have! But I like yours."

"Yeah? What's so special about mine?"

"I don't know." His face got all screwed up like he was trying to 
figure out an answer to my question. "I just like 'em. It's like, up 
until a few months ago, your chest pretty much looked like mine; now, 
it doesn't. Yours is all curvy, now."

"So? We have other differences, you know?" He laughed at my joke. I 
always thought it was sweet when my brother laughed at my jokes.

"I know, but those parts have always been different."

I was bothered that his words made sense. I was also bothered when I 
realized that he was staring at my boobs while we were talking.

I slid off of his chest and down his body, then leaned over so that my 
face was right in his. "No more staring at my boobs, okay?"

A big smile appeared on his face, and he giggled. After a few seconds, 
I realized that his smile wasn't because of what I had just told him. 

"Ew! You have a boner, don't you?" My disgust may have been convincing 
if I had jumped off of him, but I stayed where I was, feeling his stiff 
penis pressed against my cunny, with nothing between us but the thin 
fabric of his boxers.

He giggled, again.

"So, my little brother is getting all horny looking at his big sister's 
boobs, huh?"

"I'm not your 'little' brother!" He was--by eight minutes--a fact that 
I liked to tease him with whenever he was being snotty. "And, I can't 
help it!" he protested, then, softly, "It just happens."

Did I detect a little embarrassment? My brother is many things, but 
I've never known him to be embarrassed about anything!

"Well, if you're going to be checking me out, I'm gonna check you out." 
I slid down his legs, grabbed the waistband of his boxers, and pulled 
them down to get a look at his penis. He made a half-hearted attempt to 
stop me, but when I swatted his hand, he gave up and let me do what I 
wanted. (I usually don't have any trouble getting my way with him.)

His balls didn't look any different, but his penis had doubled in size 
to about three inches and was stiff so that it pointed up towards his 
head instead of pointing out, away from his body, like it usually did.

"Cool!" I said to myself--except that the word slipped out of my mouth, 
and my brother heard me. Another giggle from him. "Does your penis hurt 
when it's like that?"

"It's a little uncomfortable, but it starts to feel better once I start 
rub..." He clammed up, like I had tricked him into admitting something he 
didn't want me to know.

"My little brother plays with himself? Ew!"

"I don't... Well... There's nothing wrong with... Dad says it's okay!"

"Dad? You talked to Dad about playing with yourself?"

There was a long silence, then my brother whispered, "Yes."

I was stunned. "He told you it was alright? He didn't think it was 
nasty or anything?"

"He says all boys do it--most of them won't admit it--but they all do 
it. He said it was like practicing for sex when you're too young to get 
a girl to..."

"Ew! You're grossing me out!" Long pause. "Can I watch you do it?"

My brother blushed. He actually blushed! I don't think I'd ever seen 
him blush, before.

"Okay," he agreed, with another sheepish grin.

I hopped off of him and sat cross-legged on his bed. He lifted his butt 
and legs enough to remove his boxers then laid back down. He paused for 
a moment, looking at me for reassurance, then he wrapped his fist 
around his penis and started rubbing it up and down.

His breathing got deeper, and I could hear him inhale and exhale 
strongly, every so often. I really enjoyed watching him. His body got 
stiffer, and he started stroking faster the longer he did it. Then I 
had an idea.

"Can I try it?" I didn't wait for an answer. (Like I said, I don't have 
trouble getting my way.) I put my hand on his and forced him to stop, 
then I pulled his hand off of his penis and replaced it with mine. 

His penis felt so warm! It was weird because his skin was really soft, 
but underneath, was really hard.

I started stroking it like my brother had been doing. I wasn't as 
smooth as he was (apparently, he had had a lot of practice), but I 
could tell my brother was happy.

After almost a minute, his body got really stiff, and he let out a loud 
grunt, followed by a couple of softer grunts, then he grabbed my hand 
with both of his.

"Stop! Stop." He was breathing really hard, like he had just run a race.

"Did I hurt you?"

"No." He was still panting. I let go of his penis. "I usually stop when 
I have an orgasm. It hurt just a little when you kept going."

"An orgasm?" I was a ticked that my little brother was having to 
explain things to me. I thought I knew all about sex.

"Yeah. That's the really good feeling you get after you rub yourself 
long enough." 

"I don't rub myself there!" Okay, so I lied. I don't rub myself there 
very often. Sure, it feels good, but I don't think I'd ever had 
anything like the feeling that my brother had just experienced. "How 
come you know so much about all this stuff?"

"I asked Dad." His breathing was returning to normal.

"You asked Dad? He's never told me about any of this stuff. Mom, 
either."

"Have you ever asked?"

"No..."

"Maybe you should. When I started getting erections--that's when my 
penis gets stiff--I asked Dad about it. He told me all about it."

"It's not stiff, now."

"Yeah. It gets soft, again, when I have an orgasm. Thanks, by the way. 
It felt really good when you did it for me--much better than when I do 
it, myself!"

"Has anyone else ever done it for you, before?"

"No."

"How about Amy What's-her-face, at school?"

Jimmy laughed. "Amy 'What's-her-face' won't even let me kiss her!"

"I thought you two were...you know, like, boy-friend/girl-friend, or 
something."

"Amy tells all her friends that, but all she ever does is hang on me. 
She doesn't even hold my hand. Her hugs are nice, though."

I sat there staring at my brother's now-deflated penis. I couldn't 
believe that it had been so stiff just a few minutes ago. Now I 
understood why my brother was so fascinated with my boobs.

"Jimmy? You can look at my boobs, if you like. You don't have to act 
all sneaky trying to get a peek at them."

"Thanks. You can, um, play with my penis, again--if you want."

"Thanks."

Things got suddenly very awkward, so I told him goodnight. On impulse, 
I gave him a quick peck on his lips then hurried to my own room. (Okay, 
so like you've never kissed your brother, before? Gimme a break!)

I stood in front of my full-length mirror, brushing my hair. When I was 
done, I put my brush down and carefully considered my naked body.

Many girls I know are really self-conscious about their appearance. 
Other girls think that they're really hot when they're not. I, on the 
other hand, know how beautiful I am. No, really! I've seen how older 
guys look at me at school.

I'm not talking about those nerdy boys who still think it's nifty to 
play with frogs. I'm talking about cool boys who actually give some 
thought to how they dress and who occasionally comb their hair.

I've also noticed how teenaged boys at the mall look at me when I wear 
what my best friend, Autumn, calls my "hoochie shorts" with my 
spaghetti-strap top that shows off my belly.

But, I just like getting attention. I never really thought of myself as 
"sexy." Sure, my girl friends and I talk about being sexy, but we mean 
like "cool"--not actually "sexy." 

My brother thought I was sexy--really "sexy." So did those teenaged 
boys at the mall, I just realized. I tried to imagine rubbing one of 
their penises like I had just done Jimmy's. It freaked me out, a 
little. But, I really had played with my brother's penis, and I had 
made him feel good. I liked that. 

I put my hand between my legs and gently petted my cunny. I felt a 
tingle go all through my body. I rubbed it a little harder. I had done 
this a few times before--despite what I had told my brother--but it 
felt really special, just then.

I kept rubbing, then I let my fingers slip between my folds. I was 
surprised that my vagina was so wet. I almost thought I had peed on 
myself, but I knew better. 

I slipped a finger a little into my vagina and tried to imagine how it 
would feel for a boy to put his penis in there. (I did know a little 
bit about sex.) My thumb brushed against my clit, sending a surge of 
electricity through my body.

I rubbed my thumb in little circles as I gently pushed the tip of my 
finger in and out of my vagina. I had never played with myself this 
long or this intensely, before. It felt really good.

I spread my feet apart then opened my thighs a bit more so I could see 
inside my cunny better. That's when I noticed Jimmy standing at my door.

I quickly took my hands away from where they had been then nervously 
looked for something to cover myself up with. Nothing was handy, so I 
crossed my arms over my chest and looked down at the ground.

"What are you doing, here?"

"Watching you play with yourself." My brother smiled.

"I wasn't... Okay, I was, but so what?"

Jimmy laughed. "I came here to see if you wanted me to show you how to 
make yourself feel good--like you did for me--but I see you already 
know all about that!"

It really irked me how my brother seemed to know more about sex than I 
did.

"How would you know anything about girls?"

"Dad told me everything. I mean everything! He told me that if I was 
starting to have erections, I'd probably want to know more pretty soon, 
so he said he'd tell me now." That sounded like our father: He loved to 
hear himself talk. More than once, I had asked a simple question and 
had gotten one of his speeches. You'd think I'd learn to stop asking.

Jimmy walked over to me, reached between my legs, and gently brushed 
the tips of his fingers over my cunny. I didn't pull away. Instead, I 
let him put his other hand on my bare butt and opened my legs a little 
to give him better access.

I loved feeling his fingers running up and down my cunny. I loved it 
better when he stuck a finger into my vagina.

"You're all wet," he said softly, then he surprised me by kneeling in 
front of me and licking my cunny all the way from the bottom to the top 
in one, long lick.

I drew in a deep breath. I couldn't pull away because Jimmy had both of 
his hands on my butt, now. Not that I wanted to pull away! He went back 
and licked me two more times. 

When he realized that I wasn't trying to stop him, he moved his hands 
in front and used his fingers to spread my cunny lips apart, then he 
really went to work on me. 

I ran my fingers through his thick hair and pulled his head towards me. 
He was focusing his tongue on my clit while he probed my vagina with 
his fingers. It was incredible!

Then I felt it coming. Somehow, I knew what it was, then it washed over 
me--over my entire body: I had my first orgasm. It was more wonderful 
than I could have imagined. 

I sort of expected it to become a little painful, after what my brother 
had told me, and I was prepared to push him away, but it just kept 
feeling good--and Jimmy kept licking. He didn't stop licking my clit or 
fingering my vagina until I had another orgasm. (I later found out that 
girls can keep going, but boys need to rest, in between. Jimmy's such a 
know-it-all!)

I got a little wobbly, so Jimmy stood up and put his arms around me to 
help keep me from falling. It felt so good to feel his warm, bare skin 
pressed up against mine. It also felt good to feel his hot breath on my 
neck.

That's when the thought first came into my mind: "I love my brother." 
I'm not talking about how brothers and sisters say they love each other 
(or how parents say that brothers and sisters love each other)--I knew 
that I truly loved him. I know, "Ew," again, but I wanted to be with 
him, and I wanted to do more sexy things with him.

I pulled my head back a little to kiss Jimmy on his lips--not a 
brother/sister kiss, like we had given each other too many times to 
count--I mean a real, live, push-your-tongue-in-his-mouth kiss like the 
kind that my girl friends and I had practiced with each other at our 
last sleepover. (I know, double "Ew!")

Then it was like we were trying to climb inside each other. Our hands 
were roaming all over each other's bodies, and we were wrestling 
tongues like it was a championship match. I didn't even get grossed out 
when I realized how much spit we were swapping. (Triple "Ew!")

Just when I thought it couldn't get any more intense, I noticed that 
Jimmy's penis kept poking me. At first, it just seemed like a necessary 
side effect of our groping each other, then I realized that he was 
intentionally poking me with it. My little brother was trying to hump 
me!

Okay, that should have been another, "Ew!", but I was so hot that I 
just reached down, grabbed his penis, and guided it to where I knew it 
needed to go.

He couldn't get it into me standing up, and my bed was too far away, so 
I dropped to the ground, pulling him along with me. I tried guiding his 
penis to the right spot, again, and this time, he found it. 

"Oh!" There was a quick twinge of pain, then all I could feel was my 
brother's hot penis pounding in and out of my vagina. It lasted about 
ten seconds, then my brother pushed hard against me and grunted. After 
a few more seconds, he relaxed and collapsed on top of me. Slowly, I 
felt his penis soften then slip out of my vagina.

I must have looked a little disappointed because, after he caught his 
breath, my brother raised his head up, looked me in the eye, and 
sheepishly said, "Sorry! It felt so good, I couldn't stop. Dad says it 
takes practice to last longer."

I hugged him towards me and kissed the top of his head--not quite sure 
why he was apologizing. "That's okay, little brother. I liked having 
you inside of me."

Eventually, he did last longer--long enough to give me an orgasm--but 
he always made sure to give me at least two orgasms with his tongue 
before he'd try to stick his penis in me. My little brother's so 
thoughtful!

Okay, I know, "Ew," but once we started, we couldn't get enough of each 
other. We were on each other when we woke up in the morning, when we 
got home from school, and when we went to bed.

It helped that we would take turns sneaking into each other's beds, 
each night. Then it was my turn to be a doofus: It turns out that our 
parents found out pretty quickly; I didn't know they still checked on 
us, at night. 

They were really cool about it. They both thought it was acceptable for 
siblings to "practice" with each other. (Mom told me that she used to 
practice with her brother!) They even pretended to believe us when we 
told them we were going to start taking showers together, again, "to 
save water." (Actually, I think they were just glad that Jimmy was 
bathing, regularly.)

Once we realized that we didn't have to hide anything from our parents, 
we really started behaving like rabbits. You don't know hot until 
you've made it with your brother in front of your parents!

After a while, Jimmy started to slow down--instead of humping me, he 
started to make love to me. Soon, he was making love to me all day 
long. I don't mean we had sex all day long, I mean how he treated me. 
He would smile at me a certain way, gently brush up against me when he 
walked by, lay with me in our hammock in our back yard and just read, 
together. It was like there was this constant tension between us all 
the time that got released when he put his penis in my vagina.

Maybe, someday, I'll have a boyfriend, but right now, I have my 
brother, and I like it that way.

Having a twin is like having a built-in lover. That's what I say.
