------------------------------------

Midmorning light tore into my bedroom. My room was empty and the
house was quiet. Sunday. Abby must have been already awake. I’d
spent the better part of my sixteen years seeking solitude in
that room, but for once, it just seemed empty. I’d already grown
accustomed to having her there. In just two short weeks, I’d
accepted our cramped set-up and stopped worrying about when her
room would be fixed enough for her to return to it full time.

It had been an eventful two weeks.

Mom was already gone to work for the day. Over the past couple of
years, she’d gone from just being unfairly hard on me to seeming
to actively dislike my presence, taking on extra nursing jobs
constantly. That suited me just fine; I was happy to be away from
her venom. And it meant another day to spend alone with my
sister.

 As I went to the bathroom I realized I was again a free man. On
Saturday I had become Abby's slave for the day after losing a
childish bet and a childish argument. A day of teasing, nudity,
schoolwork, near-constant erections, and a massage before she
finally gave me release. In all, an unforgettable day.

As I went into my closet to get dressed, I thought again about
how she had commanded me to kiss and lick her ass. I'd never had
any fantasy about doing that before, but my arousal after a day
of teasing and how much it turned her on had made it very hot.
Together, we’d just been so wild, passionate, uninhibited. I
still couldn’t wrap my head around it.

By the time I managed to even really look at clothes, I had a
large hard-on. Being alone with her all day again boded well for
me. I decided against anything restrictive, and simply grabbed a
t-shirt and some loose fitting workout shorts. I went to find my
sister with a good-sized tent leading the way.

I found her on the couch talking on the phone. "I'll see you in a
bit," she said, and hung up the phone. "I'm glad you're up. My
friend Izzy's going to come over for the day and we need to go
pick her up." She jumped up and headed to my car. I was a bit put
out. My hopes for the day were shot before they started. What's
more, with someone else over with Abby all day, we'd have to hide
any indication of what was happening between us. I sighed and
followed her.

Abby had just started high school a couple of months ago, and was
having a hard time adjusting. She'd fallen out with her old
friends from middle school and had been pretty depressed about
it. Within a week of her moving into my room, she'd finally made
friends with Izzy. I knew having this friend was important to
her, so I had to be supportive.

Abby had told me a bit about Izzy. She was new to the district
and had similar trouble making new friends.

We reached her house and Abby ran to the door. As she and Izzy
walked back to the car, I saw why they'd become friends. They
acted like they’d known each other for years. Izzy was shorter
than Abby, but looked more mature, with a fuller figure and
rounder face; a bit heavy but mostly able to pull it off due to a
not inconsiderable amount of it being in her chest. Both girls
had pale, clear skin, though Izzy's seemed to somehow even be a
shade whiter than Abby's. What stood out most was their hair.
Abby had long, wavy, fiery red hair while Izzy's was jet-black
and cut fairly short. Izzy wore glasses with thick, black,
rectangular frames with small lenses.

They got in the car and Abby introduced us. I got the immediate
impression that Izzy was every bit as shy as Abby was. No wonder
it had taken them two months to become friends. It's a wonder
either of them had started talking to the other in the first
place.

We got home and went inside. Our two dogs rushed up to Izzy
excitedly, sniffing her legs. I pushed them back, trying to get
them off her.

"It's ok, I like dogs," Izzy said. She patted my German Shepherd,
Willow, on the head. The dog took an immediate liking to her and
started following her.

They headed to the couch to watch a movie. I headed into my room
for a while to give them some space.

After killing some time, it was nearly lunchtime, so I headed
back into the living room to check on them.  I walked up next to
the couch on the side near my sister. "How's it going?" I asked.

"We're doing ok," Abby said. She wrapped one arm around my legs
and hugged me. "You need anything?"

"Nope, just checking on you."

"That's nice of you," said Izzy. "Are you two very close? I
always wondered what it would be like to have a brother."

"Yeah, we're pretty close," Abby replied. "He's sweet and takes
care of me. Just yesterday he helped me with my school project."
Still hugging my legs with one arm, she turned and looked up at
me, her nose almost brushing my dick through my shorts.

"That's cool, especially since you're about the same age," Izzy
said.

Abby looked back to Izzy. "Yeah, he's just a year older than us."

"This is my favorite part," Izzy said, looking back at the movie.
Izzy and Abby watched, and I stood there, my mind wondering again
to the day before. I had stood in the same spot by the couch, and
Abby had teasingly stroked and kissed at my dick for a few
minutes until her show came on.

I was shot back to the present by Izzy's voice. "Do you like this
movie?" I realized she was looking at me.

"Uh, I wasn't really paying attention," I said. "You girls want
any lunch?"

"No thanks, we already had some popcorn," said Abby, pointing at
the bowl.

"Alright. Enjoy the movie," I said. Izzy and Abby looked from me
back to the TV. As I pulled back from Abby, I felt my dick rub
the side of the head just a second, and realized I was sporting
another large tent in my pants. Thinking about the day before had
set off my hard-on again. I ducked into the kitchen as quickly as
I could.

Had Izzy seen it? I wasn't sure. I'd become so used to being
horny around Abby at home, I wasn't aware of it happening, even
with company over. I was mortified at the possibly that Izzy
might guess what Abby and I were doing. Izzy had talked to me and
looked at me while I had it, surely she noticed it. And it was
sitting there right next to my sister's face. I was almost in a
panic, but tried to think reasonably. There are a hundred reasons
a teenager might get a hard-on without it having to do with his
sister. Even assuming she'd seen it, there's no reason to believe
she'd even think it was related to Abby. I got some lunch and ate
in the kitchen.

Soon their movie ended and Abby stuck her head into the kitchen.
"We're going into your room for a bit. Is that ok?"

"Sure." After she left, I thought some more, and realized that
might not be the best idea. My dick now as limp as it'd been in a
week and a half, I practically ran to my room. They weren't there
yet, and I heard them through the connecting bathroom in Abby's
room. They walked through the bathroom into mine.

"That sure sucks about your room, Abby," Izzy said. "No wonder
you needed some new clothes. It’s nice of your brother to share
his room for a while."

They saw me as they came in. "I just wanted to straighten up a
bit for you."

"Don't worry about me," Izzy said. She sat down on my bed, Willow
following behind her and sitting on the floor in front of her.
"Have you been sleeping in that thing for two weeks?" Izzy asked
me, pointing at the rolled up sleeping bag in the corner. I'd had
a hard and uncomfortable night in it the first night when Abby
came into my room. The next night, Abby had insisted I sleep in
the bed, so we'd shared it, leading to our first encounter. Since
then we'd shared the bed every night. The first week, I'd left
the sleeping bag out for appearances, but since Mom never came
into my room, after that I'd gotten lazy and left it rolled in
the corner.

My heart raced as I looked at it. I'd dropped my backpack on it
Friday after school, where it had sat ever since. It was another
possible clue. Not thinking to answer her, my eyes darted across
the room, trying to see anything else that could give us away.
The bowtie Abby had made me where the day before was sitting out
on my computer desk. The computer itself had lots of porn,
including plenty of pictures of redheads much like my sister.
Abby's pair of shorts she wore for pajamas laid on the floor, the
crotch showing patches of white where her juices had soaked them.
Evidence seemed piled against us everywhere. Our private
alternate dimension was suddenly a part of the real world.

Again I forced myself to stay calm. While to me all those things
were reminders of what Abby and I had done, to anyone else they
were just curious tidbits, dots Izzy wouldn't even know were
connected. I gathered myself enough to answer Izzy. "Yeah, it’s a
little hard on the floor, but I've gotten used to it."

Then I realized another clue we may have left behind. Several
times I'd cum hard in Abby's hands and had shot spurts wildly,
not caring where they went at the time. I tried to look around
nonchalantly while I straightened for any telltale spots of white
in strange places. On my bed sheets, maybe 12 inches from Izzy,
was a line of distinctive white spots. I looked at Abby with a
bit of a scared expression, and her eyes followed mine to the
spot. She walked over and sat on the bed next to Izzy, scrunching
the sheets up to conceal it.

"It must be hard sharing a room together. Do you take turns
getting ready in the morning?" Izzy asked.

Abby spoke before I could. "Usually, I get up first, take my
stuff and get ready in the bathroom so he can get ready in here."
I stupidly nodded in agreement, unnecessarily trying to reinforce
her story.

"Still, it must be a bit awkward not having much privacy. Have
either of you ever, um, walked in on the other naked?"

My mind shot back to the morning after the night I spent on the
floor. I'd taken a shower and walked back into my room naked to
get dressed, as I usually did. Abby had been in my closet getting
herself ready, and was naked too. We'd stared at each other in a
bit of shock, seeing each other naked for the first time since we
were young. It was the first time I saw her soft tits, her round,
firm ass, the bright red pubic hair and the outline of her pussy.

Abby again spoke first. "No. We're pretty careful to give each
other some space." My eyes met with Abby's at that one, and she
couldn't help but smile at me.

I decided we needed to change the subject. "So Izzy, you're new
to the area?"

"Yeah, my dad and I moved in over the summer."

"How do you like it?"

"It was pretty hard, but I'm having more fun now that Abby and I
are friends."

"So you just live with your dad?"

"Yeah, my mom died a couple of years ago."

"I'm sorry." That was a conversation killer, and for a moment we
all just sat silently. I decided it was time for me to leave them
alone. "I'm going to watch TV a while and get out of you girls'
hair." I stepped out the door, but left it open a few inches.
Still worrying about what Izzy might know, I stood just outside
and listened.

"So do you have to share the one computer, too?" asked Izzy.

"Yeah, mine was damaged in the flood, and I haven't gotten a new
one yet," Abby answered.

"Have you found anything interesting on there?"

"Uh, what do you mean?" I could hear the tension in Abby's voice.
I tried to come up with some excuse to go back in and interrupt
them.

"Guys like to look at stuff on the Internet," Izzy said
awkwardly.

"I wasn't really looking for anything like that," Abby said,
trying to side step the issue.

"Have you ever had a real boyfriend?" Izzy asked. She seemed all
over the map.

"No. I've only been on a couple of dates, nothing that was
serious. I didn't like them."

"Same with me. Most guys aren't as nice as your brother," Izzy
said. They both seemed a little bummed, and again Izzy changed
subjects. "Who needs a boy anyway? Have you ever looked at porn
online?"

Standing in the hall away from the door, I could almost hear the
two of the blushing as they talked. I was already having to
reconsider the reading of ‘shy’ I’d gotten for Izzy. "A couple of
times," Abby said meekly. She had indeed.

"I do sometimes. A lot of it is weird, but some of it turns me
on." Both girls started giggling, trying to break the tension. "I
really like guys doing oral on girls. I imagine him doing it to
me. How awesome would that be?" They giggled again.

After the last two weeks, Abby knew quite well what that was
like. It had quickly become a favorite.

"I bet it's nice," Abby said. Her voice almost cracked when she
said it. For a minute, they talked more softly, and I couldn't
here. Izzy seemed to be prodding Abby a bit.

"Come on, tell me. I told you my favorite. What do you like
looking at?" Izzy said.

"Well, there was one series of pictures I liked. The guy was
lying naked on the bed with the girl on top of him, right in his
face. He was eating her out while she was sucking on him. She sat
up and pressed into his face and stroked him." This wasn't any
porn she'd seen, she was describing what we'd done the night
before. "They, uh, you know, orgasmed at the same time. He pulsed
in her hand and shot off like a cannon, all over her." Abby
paused a moment, apparently lost in thought. I was shocked to
hear her talking like that to someone other than me. Their
friendship really had grown quickly.

"Sounds pretty fun," Izzy said.

"It was. Knowing how turned on he was the best part. He came so
hard. His sperm felt so warm as it dribbled down." Abby stopped,
catching herself. "That’s what I imagined, anyway," she added
quickly. There was silence. I wished I could see the look on
Izzy's face, I wish I could know what she was thinking. Had Abby
given us away?

Abby quickly changed the subject to clothes, and both chattered
on about that, their sex talk seemingly forgotten. After a few
minutes of listening, I decided we were probably safe, and went
into the living room.

A bit later, both girls came out. "We need a guy's opinion on
Abby's new clothes," Izzy said.

Abby and Izzy had gone to the mall earlier in the week and bought
some clothes. I followed them back into my room. I had little
interest in fashion, but would play along for Abby's sake. Plus,
it might give Abby a nonchalant opportunity to pose herself for
me.

Abby went into the closet to change. I sat in the computer chair
and Izzy on the bed, scratching Willow's head idly. The first
outfit was dark jeans and a black blouse. It was pretty modest
and I was pretty bored. "Looks great."

Abby changed into her next shirt. It was a tighter t-shirt, again
in black, with some white large white prints across the front.
"Uh, it fits you well."

"You need to do better than that," Izzy said. I tried to think of
something better.

"The black really shows off your nice skin," I said. It was
apparently good enough. A few more outfits followed, clearly
showing Izzy's influence. I made similarly dull remarks. Finally,
Abby seemed done and sat down with Izzy.

Izzy nudged Abby a bit, giggling. "Show him the last one."

Abby appeared tense. "I don't know if I should. That was just for
fun."

"Come on, he can give you a guy's opinion" Izzy said. I was
pretty curious now.

"But he's my brother." Whatever it was, I knew that wasn’t really
the problem. She just didn’t want to show me with Izzy there.

"It's not a big deal. Besides, who else are you going to show it
off for?"

Abby clearly wanted to show it to me, and Izzy's arguments were
apparently good enough excuse to let her do it with someone else
there. Abby returned into the closet. As we waited, I looked over
at Izzy. She had her head down, with a small, sly smile on her
face and was looking at me, but cast her eyes down when I looked.
She looked like the cat who'd swallowed the canary. Her eyes
moved up to the closet.

I realized the door was open and Abby was standing in front of
me. She was wearing a black corset on her top, squeezing her
breasts together. Her long, curly red hair fell over her
shoulders, covering them. Below her exposed and flat belly was a
garter belt with frills dangling down a few inches. The panties
were black but partially see-through, and her red pubes were
clearly visibly through it. The garter belt connected down her
thighs to the black stockings that covered her shapely legs.

She posed a bit in it, turning around and bending slightly to
show off her butt. Her white, round cheeks and crack stood out
clearly through the panties.

"What do you think?" Izzy interjected.

If I had been thinking more clearly, I might have pretended to be
uncomfortable at the sight and somewhat mad at the thought of my
sister having that to show a boyfriend. As it was, I barely
managed an "uh, it looks good on you." My mind was totally
wrapped in the sight of Abby's body.  I couldn't help but stare,
and Abby was looking right back at me.

"I need to go to bathroom," Izzy loudly. "I'll be back in a few
minutes." She went into the adjoining bathroom, leaving me alone
with Abby. I stood and stepped to her. She leaned and whispered
in my ear.

"I got this for you," she said. Our lips met in a kiss. With one
hand I grabbed her ass and with the other started rubbing at her
pussy through her panties. Her hand slid up my loose pant leg and
grabbed my dick. She pulled it free from my pants and stroked me
as we kissed.

We held it for just a moment, and then quickly pulled ourselves
apart, anticipating Izzy's return. In one quick motion I sat in
my chair and tucked my dick back away, placing my hands so as to
try to casually conceal it. I turned my attention nervously to
the bathroom door.

My heart skipped a beat. The door wasn't quite closed all the
way. No one forgets to do that in someone else’s house. Izzy
pushed the door open, and came back in with the same coy look she
had earlier. She hadn't even thought or bothered to flush before
she came back in. She must have been watching us!

She tried to act though nothing was different, but quickly saw
from the horrified, silent expressions on Abby and myself that we
knew it was. Her smiled dropped away, and she seemed suddenly
ashamed. "I'm sorry," she said so quietly I could barely hear
her. I think if she hadn't needed us to drive her home, she'd
have run out of the house right then. "I didn't mean to spy on
you or trick you, I mean, I was just trying to see if you guys
really were, I mean..." She was near tears.

I was terrified. This girl knew. There was no doubting it now. I
was suddenly aware of how bad discovery could be. If she told
anyone, Abby and I would be ostracized. We'd never be able to
show our faces at school. And if Mom found out! She'd split us
up, maybe even me away to live somewhere else. It would crush us
both.

Abby was near tears, too. "Please don't tell anyone," she begged
Izzy.

"Of course not, I wouldn't, ever." We all sat and stared at each
other. Even if she didn't, this could mean the end for Abby and
me. This shock alone could break the spell that had been over us.

"I think we'd better take you home now," Abby told Izzy. It
seemed this might also mean the end of their short friendship.

"Please, I'm sorry, Abby. I still want to be your friend."

"I don't know if that will work."

"There has to be some way to make this better," Izzy pleaded. I
could tell she was heartbroken herself. She had pushed too hard
and had broken the one friendship she'd been able to make. She
reminded me so much of Abby I couldn't help but feel sorry for
her. Still, I didn't see any way to fix it.

"I'm sorry, Izzy, but even if you never tell, if you were still
friends this would just seem like a gun pointed at Abby, waiting
to go off," I said.

We sat silently a minute, then I stood up, ready to go.

"Wait!" Izzy said, standing up. "What if..." she hesitated,
speaking softly. "What if you knew something like that about me?
Then we'd be even again." She seemed genuinely desperate.

"I don't know," I said. "It would have to be something we'd know
it was something that could ruin you as badly as this would us.
And we'd have to know for sure it was true." It seemed unlikely
Izzy had such a secret herself.

"There is something. I've been doing it at home for a while. If
people found out about it, I could never show my face again."
Izzy was torn between two possibilities that scared her, and it
showed. "Ever since I've started, I've worried that people would
figure it out, that they'd somehow know. It scares me every day."

I thought a moment. "Alright," I said. "What is it?" Even if it
couldn't restore their friendship, dirt on her might at least
help ensure her silence.

"I'll have to show you, she said." I moved over next to Abby.
Izzy sat down in the computer chair, placing her purse on the
floor next to her. She put her hands on her pants as if to
unbutton them, but hesitated. "I've never imagined doing this in
front of anyone else before," she said. "It'll take me a minute
before I really start." Abby and I sat down on the bed as Izzy
undid her pants. She closed her eyes, took a deep and pulled them
off with her panties.

For the first time, really, I looked at Izzy's body. Her skin
looked as smooth as Abby's, her face soft. With her short, black
hair she reminded me a bit of Snow White.  Still covered by her
shirt, I could tell her tits were bigger than Abby's. Seeing her
in her normal school clothes, I hadn't noticed, but in the
t-shirt she was in today, she clearly had D-cups. She had a thin
layer of fat on her belly but firm thighs. Though her waist was
bigger than Abby's, so were her hips, making her body look more
mature despite her face.

Between her legs her pubes were as black as the hair on her head.
Even with the dark color, I could tell it was denser than Abby's.
It was trimmed to a uniform, short length. From my experiences
with Abby, Izzy seemed to be aroused already, as her pussy lips
were wide open and glistening.

Until then, I had just seen Izzy as a competitor for Abby's time
and little more. Seeing her suddenly part naked in front of me, I
wasn't sure what I felt about her.

"I need to get ready a little first," Izzy told us. She started
rubbing on her pussy, her eyes still closed. I still couldn't see
where she was going, or what she thought was as damaging as
incest. She continued rubbing on herself, her body relaxing some.


She stopped and opened her eyes, looking at us both, more ashamed
than I could ever remember seeing Abby. "Please don't think I'm
gross," Izzy said. She turned the chair away from us and bent
down to her purse and fiddled there for a moment. She turned back
towards us, leaned back and spread her legs again. I saw she had
something smeared across all her fingers of her left hand and
down nearly to her palm. It seemed gooey, and she held her hand
up to keep it from running. She reached down and smeared some
onto her pussy.

She reached her hand down, and I suddenly realized what she was
doing. Surprised, I looked over at Abby next to me. Her eyes were
wide open and staring at what was unfolding, and her hand gripped
at the sheet.

Izzy's hand reached towards my dog Willow, who was interested.
Even as Willow took a few licks of the stuff, I caught a whiff.
It was the sweet smell of honey. Izzy drew Willow in between her
legs with the honey on her hand and brought to her thigh,
smearing some up to the top of her thigh. Willow's tongue lapped
at the honey, following the trail up her leg until each lick
ended on the edge of Izzy's pussy lips. Not hesitating a moment,
Willow started licking straight up on the side of Izzy's pussy.
When she'd cleaned it off, she moved to the other side. Izzy
reached down and applied some more, this time deep between her
fat pussy lips. She leaned back more and closed her eyes.

Willow tongue dove deep inside, looking for every last drip of
honey. Izzy was breathing more heavily, and with her free hand
was caressing her pussy around Willow's tongue. With two fingers,
she slowly separated her lips, letting Willow in deeper and
deeper. Pushing her aside for just a moment, Izzy lathered what
was left of the honey into her pussy, and Willow dove back in.
Continuing to spread herself apart, she took her other hand and
started rubbing vigorously on her clit.

It took her just a minute more to cum. Her butt lifted slightly
from the chair and she could barely keep herself from squeezing
Willow's head between her thighs. Willow, completely undeterred,
slurped rhythmically into her, her long, fat tongue nearly
vanishing deep inside Izzy's pussy with each lick.

Settling back into her seat, Izzy released herself and gripped
the arms of the chair, eyes still closed. Willow's tongue
continued to lick at her, moving farther up to clean off what
Izzy's hand had smeared on her clit. Izzy gripped the chair
tighter and exhaling, thrust ever so slightly again.

Willow gradually lost steam and Izzy pulled her gently aside,
closing her legs and sitting up. Abby and I just sat silently,
still watching her. Blushing, she got up, grabbed her pants and
went into the bathroom.

She came back in fully dressed and stood before us, as if
awaiting judgment. "You do that at home, too?" I stammered.

"Yeah, I have a lab. I saw it on the Internet, and once I'd tried
it, it felt so good I just kept doing it. Every time a dog sniffs
me, I'm just sure everyone will guess that it’s more interested
than it should be. And I know every boy would think it’s gross.
I've tried to stop, but every time I get real horny and do it
again."

Izzy seemed near tears again, possibly regretting her decision to
show us. None of us knew really what to do next. We'd all seen
our more private secrets exposed, but nothing quite seemed to be
broken. Abby finally broke the tension. She stood up and gave
Izzy a hug. Izzy started crying and seemed to melt a bit in
Abby's arms. Her tension seemed to slowly ooze from her. Abby
looked inquisitively at me.

"I think everyone has secrets they keep from people who are too
judgmental. If it feels right and no one gets hurt, I don't see
how it can be so bad."

"So we're ok, then?" Izzy asked.

"I think so," I said.

We all went in and sat down on the couch. We spent an hour
watching TV silently, processing and coming down from the
adrenaline rush of what had happened. We left to take Izzy home
before Mom got off work. As we dropped her off, I wondered just
how our new revelations would change things.
