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

It was after school on another Friday, and I headed to my car. My
sister Abby was already there, waiting for me. With her was her
new friend Izzy. I'd been giving rides home every day this week
so she wouldn't have to ride the bus. They were chatting happily
as we got in the car. My eyes met with Izzy's for just a moment
as we got in. There was still weirdness between us two.

It had been a week since Izzy had discovered the incestuous
relationship Abby and I had while she was over at our house. The
shock of it and the fear that she could expose us nearly caused
Abby to end her short friendship with Izzy. Desperate to keep the
only friend she'd made since she came to our school district,
Izzy had exposed to us her own deep secret to try to restore
balance.

Sunday had been only the start of what turned into the most
angst-ridden week of my 16 years. After dropping Izzy off, Abby
and I had gone to bed together in my bed, as we had almost every
night since a storm had flooded her room. Still overcome by the
embarrassment of the evening, we'd gone to sleep for the first
time without touching each other, somehow managing to barely
touch at all on my twin bed.

On Monday, my friends at school had been making fun of me for not
ever having a date and always hanging out with my sister before
and after school. One of them had even suggested I date Abby. I
knew he was just screwing with me and didn't have any idea what
was happening, but simply knowing the idea was even in their
heads scared me. I knew we'd have to distance ourselves more in
public.

All the stress had set back our hormones, as well. Lying in the
dark in bed Monday night, I had felt relief more than anything
when Abby's hand reached over and started feeling my dick. I'd
fingered her and she'd jacked me off as we'd done before, but it
seemed a little different than before, with more nervousness and
less zeal.

We came home on Tuesday to find that the contractors had finally
arrived to work on Abby's room, and had already replaced the
damaged drywall and the broken window. Once the carpet was put
in, the room would be ready for Abby to return. It seemed that
our time sharing my room may have been ending soon.

That night at dinner, our Mom seemed to sense Abby’s discomfort
and later pulled me aside. She had incorrectly guessed that it
was because of Abby's lack of privacy, and had told me to give
her some space and spend a few nights fighting the dogs for the
couch.

It seemed like the universe itself was pushing us apart. I spent
all day at school on Friday wondering if the end was near with
Abby. We'd have to stay away from each both at school and home.
The one time we'd done something this week, it hadn't been the
same, and soon Abby would be moving back into her room. With all
the tension around us now, it wouldn't take very long for
pretending to not want to spend time together became reality.

I knew that wasn't what I wanted. My new relationship with Abby,
short as it had been so far, was the most exciting thing that had
ever happened to me. I wanted to wait until this blew over, and
continue with her just as before. But did she feel the same way?
I was afraid to ask. Even knowing now how much she seemed to
enjoy it, I still didn't want to pressure her into anything, and
I knew if she saw how I felt, my shy, sweet sister would have a
hard time turning me down.

These thoughts still swirling in my head, I started the car and
headed for Izzy's house. The lone good thing this week was that
Abby and Izzy's friendship had seemed to be holding up. Listening
to her talk to Abby, I realized I wasn't the only one worrying.

"What are you doing tonight? Did that boy ask you out?" Abby
asked.

"No. I don't think he was even interested in me. Everyone here
seems to think I'm weird," Izzy replied. I said nothing, but
thought she was right. Just from hearing some of my friends talk,
people did think there was something off about her. I could see
why. Izzy was as shy as Abby, and now I knew that the weight of
worry from her 'dark secret' just added to the distance she
showed to other people.

"That sucks, Izzy," Abby said. "Don't worry, you'll get a date
before too long and then everyone will know you're not weird."

"I hope so. Are you two up to anything tonight?" Izzy's tone
sounded a bit perkier with the last question.

"No. Everyone thinks it’s weird that we spend so much time
together. We've had to stop going around together all the time,"
Abby said. "Wait a second..." Her voice perked up, too. "I just
had an idea of how to solve everyone's problem."

"What is it?" Izzy asked.

"You can date my brother!"

I nearly drove through a stop sign, slamming us to a late halt.
Izzy and I were still awkward around each other, the suggestion
seemed unnatural. Was this Abby's way of trying to end our own
fling, setting me up with someone else? "I'm not sure that's a
good idea," I said.

Izzy seemed similarly surprised. "Yeah, I don't get it. I don't
want to come between you and your brother, Abby."

Abby laughed. "You wouldn't date for real, you'd only pretend.
Getting seen together on dates will help both your reputations at
school." She looked at me. "And if you're dating my best friend,
it'll give us an excuse to all hang out together."

It seemed brilliant. Just hearing the excitement in Abby about
getting to be with me put me on board.

"It sounds okay with me if it’s okay with you guys," Izzy said.

"Yeah, that makes sense," I said.

"Great. You can have your first date tonight. I know a bunch of
people are going to the movies tonight, we can all go there. You
two can go in first and make sure you're seen, and then I'll
follow in a bit later. We can go to a movie none of them would go
see and all sit together." Izzy and I agreed.

We arrived at Izzy's house. As she got out of the car, Abby said,
"Both of you make sure you dress as you would on a first date."

At home we picked out our movie and I got changed, wearing slacks
and a dress shirt. We told Mom about my ‘date’ with Izzy, which
she grudgingly approved with her usual cold, warning look at me.

We drove down to Izzy's house to pick her up. She came out
looking different than I'd ever seen her. Far from her usual
jeans and t-shirt, she was wearing a black dress. It had thin
straps and fit snuggly over her large breasts, going down to just
above her knees and flaring out at the bottom.  It was low cut,
trampy, even.

"You look very nice," Abby told her as she got in the car.
"They're sure to notice you."

"Thanks," Izzy said.

We arrived at the Cineplex. "Go on in, and remember to act like
you like each other. Hold hands, even," Abby instructed us. "I'll
be in after you in a few minutes."

Izzy and I got out and stood next to each other a moment, both
feeling awkward. "Nice pants," Izzy commented, sounding a little
snarky. She avoided looking directly at me.

"Thanks," I said in a similar flat tone. We reached our hands out
and loosely put them together. It seemed colder than Abby's hand.
Feeling strange, we walked inside together.

We seemed quite successful at getting seen, and I noticed a
number of people from school looking at us and commenting to
their friends as we waited in line. We talked idly a bit and
tried to act happy, each of us laughing regularly. We bought
concessions and headed into the movie.

As we turned into the dark hallway, out of view of anyone, Izzy
released, almost yanking her hand back. “Your hand feels weird,”
she said, matter-of-factly, still avoiding looking at me. We took
some seats at the top of the theatre. We said nothing as we
waited. I wondered if maybe she just didn’t much care for me, but
at the same time had a vague sense that maybe, on some level she
was trying to avoid, she would be okay with what we were doing.

I watched intently for Abby to come in. After a minute, I decided
to break the silence. "Thanks for doing this for us, Izzy. I
think it'll mean a lot for me and Abby."

"I'm glad I could help. I know how hard it is to keep something
important to you secret." My mind shot back to the week before,
when she'd shown us her secret. Abby and I had watched as she'd
taken off her pants, rubbed honey on herself and let my dog
Willow lick her to orgasm. The picture of her pussy blazed
briefly in my head, and I became aware of how close by that same
pussy was now, up a short dress and under some panties. The
memory made me uncomfortable sitting so close beside her. I
longed for Abby to show up.

After another minute of silence, Abby finally entered and walked
up the steps to us. I scooted down a seat and she sat down
between us. "How'd it go?"

"Pretty good," I said. "There were a lot of people from school
out there who saw us."

"Some of the boys were clearly ogling me," Izzy added with a
smile.

The lights went down and the movie started. I reached my hand
over and grabbed Abby's, squeezing it tightly. Feeling her
familiar fingers wrap around my hand calmed me down completely.
The world seemed to be on our side again.

The movie was terribly boring. We'd picked a drama that had been
out a few weeks, a prestige film where everyone's mostly
interested in trying to win an Oscar. We knew that none of the
other high-schoolers would be in there, and the theatre was all
but empty. The closest other people were six rows in front of us.


Half way through the movie, Izzy leaned over Abby. "Shouldn't you
two be making out or something?" Abby giggled a bit.

I wrapped my arm around Abby's shoulder and we leaned into each
other and pressed our mouths together. We let our lips gradually
melt together, and our tongues wrapped around each other. She
reached over and grabbed my other hand, bringing it to her
breast. I cupped and rubbed it through her shirt and bra. She
reached down and started rubbing my dick through my pants. Soon
my hard-on bulged through, bending uncomfortably, and I shifted a
bit automatically.

Separating our lips a moment Abby leaned toward my ear. "Your
pants are a little tight, don't you think?" She started working
at opening my pants. Having trouble on my belt, I released her
tit long enough the reach down and undo it myself. As I
unbuttoned and unzipped, I saw her reach behind her back and
unclasp her bra, then push the cups up, freeing her tits inside
her shirt. I slid my hand up her shirt and found her bare breast,
running my fingers around her areola and pinching her nipple as I
cupped her in my palm.

Her hand returned to my crotch. She slipped into the top of my
underwear and grabbed my dick, pulled it loose of its prison. My
head lay against my shirt on my stomach, and Abby ran her fingers
up and down along my shaft, tickling a moment right at the place
where my skin connects to the middle of the head.

As we made out and touched each other, I wondered how much of
what we were doing was being noticed by Izzy. After a week of
frustration, I wasn't about to stop now because of that, but I
hoped she wasn’t paying too much attention.

All too soon the credits started to roll. Abby put her bra back
in place and I somehow forced my dick back into my pants. Izzy
stood up about ready to go, but Abby tugged her arm. "I think my
brother needs a minute before he's ready to get up," she said,
clearly referencing my hard-on. Izzy looked over at me smirking,
embarrassing me a bit by looking over again a second later.

It indeed took a few minutes before I was ready to get up, and we
all walked to the car. It was only about 9 and Abby and Izzy
wanted to spend time at our house for a while before calling it a
night.

When we got home, Mom was still up on the couch. We told her Izzy
was staying a while, which was approved as long as we got her
home before eleven. With a glare Mom pulled me aside. She seemed
to be thinking about making some comment about me and Izzy, but
instead just told me the couch would be free for me to sleep on
by then, with a follow up warning to behave myself. Frustrated at
again not getting to spend the night with Abby, I followed them
into my room.

Izzy was sitting in the computer chair and Abby was on the bed,
talking. I went in and plopped down next to Abby on the bed with
my back against the wall. My plan was to wait out the next hour
or so while Abby and Izzy chatted, then we'd take Izzy home and I
might finally get some alone time with Abby.

"Did you two enjoy the movie?" Izzy asked us. Somewhat
embarrassed, I just nodded.

"I know I did," Abby said. Both girls giggled. I picked up a book
and tried to ignore them and read. Abby leaned toward Izzy and
continued in a quieter voice. "Can you believe we did that in a
movie theatre?" It was clear that Abby was excited to have a
friend she could finally talk to about this stuff. I wondered how
much Abby had actually told Izzy about what we'd done over the
past week. Last Sunday, Abby had described one of our encounters,
trying to pretend it was from some porn she'd seen online, but it
seemed likely that Izzy had realized it was us. I kept trying to
read.

"I bet that was fun. Touching him in there must have been pretty
hot," Izzy, said more quietly. So she had seen what we were
doing. Had she actually been able to see my dick? How much could
she make out in the dark? I realized it wasn't that big of a
deal. On Sunday, she had seen the tent in my pants just a few
feet from her at one point, and later on she had watched from the
bathroom while Abby and I had groped at each other. She'd of had
a much better view of my dick in Abby's hand then.

They continued in whispers and giggles for a minute, which I
tried to not listen too. "Next time you go to the movies, you
should suck on his dick," Izzy squeaked in an excited whisper. I
liked the idea, but still said nothing.

Their conversation turned a bit, and Abby told Izzy about our
past week of inactivity as I slept on the couch.

"That sucks," Izzy said. "Do you have to sleep there again
tonight?"

I looked over the book. "Yup."

"That's too bad," Izzy said. "You have a bit of time now,
though."

Abby seemed to agree. She scooted over toward me and started
kissing me. I pulled back. "Um…what about…” I gestured my head
toward Izzy.

"I don't mind," Izzy interjected. "I know how you must feel; you
two need some time together. Just pretend I'm not here." She
turned around in the chair and faced the computer.

We couldn't very well send her out to sit with our Mom. I felt a
little awkward at the prospect of doing more in front of Izzy,
but at the same time, worried it might be the only chance we got.
I figured a kiss wouldn’t hurt, either way. We started kissing
again, as deeply as ever, and I could feel our saliva mixing as
our tongues twisted. She rubbed my chest with her hand, and our
hormones took over. My hand went again to her breast, and she
wasted no time in unbuttoning my shirt. Tossing my shirt away, we
wrapped our arms around each other and held each other tightly
while sitting on the bed, kissing deeply.

"You didn't really get a chance to enjoy my new outfit last
time," Abby whispered to me. She got up and walked to the closet
and I moved to sit on the foot of the bed right near the closet
door. Very aware that Izzy was in the room, I turned toward the
head of the bed where she was sitting. She was still facing the
computer, back turned to us. I wasn't sure I could go much
further with her in the room.

Turning my attention back past the foot of the bed to Abby in the
closet, she was stripping under the single light bulb directly
over her. Facing away from me, she shed her shirt and bra, and
then slid down her pants and panties over her ass. She continued
pushing them down slowly, bending at the waist as she did, until
her pussy showed between her legs right under her spread butt
cheeks.

She dug out her lingerie that she'd modeled for me last Sunday.
Seeing her in it before had led to us getting caught by Izzy in
the first place. She pulled the corset on over her head,
adjusting it to fit, then pulled on the garter belt and the
see-through panties. She turned, sitting on the short chest in
the back of the closet, and slowly pulled on each stocking,
fastening them to the belt.

She posed, turning to show me the back. Walking out of the
closet, she was right in front of me at the foot of the bed. She
opened and removed my pants, leaving me in just my boxer-briefs
and undershirt. She climbed up on top of me, straddling me, and
our lips and tongues met once again. My hands grabbed at her tits
through the stiff corset. I felt her pussy against the length of
my dick through the fabric of her thin panties and my underwear.
Abby started slowly but firmly grinding up and down along my
dick, until I could feel the moisture from her pussy seeping
through.

Abby got off me and pushed me back farther onto the bed. She
pulled off her corset, and I stared at her tits as she then
quickly undid the garter belt and removed it. Next she slid her
panties off, showing the red fuzz around her pussy in all its
glory. She crawled up the bed to me and pushed me down onto my
back. As I landed, I happened to look up towards Izzy again. She
had turned her chair part way around, and her eyes were locked on
us. By now, I no longer cared if she saw us.

Abby was now wearing only the black stockings that covered her
legs from her feet to her thighs. With a few jerks, she pulled my
underwear off. She straddled across my right leg and grabbed my
dick in her hand. Stroking me, she lowered herself onto my leg.
Her lightly haired, wet pussy lips were spread wide open and I
felt them rubbing up and down my leg. She leaned down and guided
my dick into her mouth, wrapping her lips around my head. She
ground harder on my leg and she took my dick deeper into her
mouth until her lips were half way down my length.

Pulling off my dick, she slid up my leg and then straddled across
my waist, dangling her tits over my chin. I cupped them in my
hands, and then stretched my head up, licking and sucking on each
nipple in turn. Abby lowered her hips, pressing my dick against
my stomach with her pussy, the fullness of its lips wrapping
partly around the length of my shaft. It was the first time I'm
felt her pussy on my dick, and its warmth and wetness almost made
me cum into my own belly button right then. I was terrified, yet
still slightly hopeful, that I might slip inside her then and
there. While exciting, I knew that full penetration wasn’t a good
idea. I tried to focus my attention on sucking her tits.

She began grinding again, pressing her clit into my shaft. Her
pace quickly increased, her breathing matching, and she soon
came. She pressed her clit harder onto my shaft and dropped her
body on top of me, wrapping her hands under my armpits and
grabbing my shoulders, holding me tightly. With each spasm she
thrust her hips into me and held a moment before repeating.

She released her death grip on my body and sat up on me, kicking
her legs out in front of her and worming her feet under my
shoulders. Her pussy was open in front of me, the bottom of her
lips still resting on the base of my shaft. Leaning back on one
hand, she reached with the other and lifted the head of my dick
off my stomach. She stroked and brought it up closer to her
pussy, and grabbing each of her thighs, I raised myself into a
sitting position with her on top of me.

She scooted back just a bit and pulled my dick to her, rubbing my
head on her pussy. She rubbed me along the outside of each lip,
as if my dick were her toy. My head was wet with pre-cum and her
juices, and highly sensitive. I felt the red fuzz on her pussy
acutely.

Abby slid the very tip of my dick between her pussy lips, and
started rubbing it up and down along the length of her pussy. It
took all my willpower not to grab my sister by the hips and
thrust myself into her right then.

She started stroking my faster, bringing my dick up a bit higher
and rubbed the end against her clit. We were both breathing hard
and Abby let out a soft "Mmmmmmm".

Her moan put me over the top. My dick jerked fiercely in her firm
grip, shooting the first spurts onto her stomach. I savored each
pulse I made in her hand, the rest of my cum squirting out in
great gobs on her red bush. Even after I'd stopped cumming, she
held my dick firmly against her clit. Finally letting go of me,
she moved her hand onto her bush and rubbed my cum into her hair,
her eyes closed.

Totally spent, my awareness and sense of shame returned, first,
that I’d let it almost go too far, and second because of our
guest. I put my hand on my dick, trying to cover it. I glanced
over at the computer chair where Izzy sat. She had been just a
few feet away from me the whole time, if I had wanted I could
have reached my arm out and touched her leg. Her proximity
embarrassed me. Then I saw what she was doing.

She had turned her chair part way around, turning her head to see
the action. The rest of her was facing my eyes. She had slid down
in the chair to the edge with her legs spread apart. Her hand was
up her dress rubbing herself. With a straight view up her dress,
I could just see her pussy covered in short black hair under her
fingers.

Abby dismounted me and went back into the closet. I got up and
went to collect my clothes, trying to not look at Izzy and ignore
the fact that she was probably watching my butt as she touched
herself. I ducked into the bathroom to get dressed and lingered
there, not really wanting to go back in with them. After a
minute, I heard them giggling and whispering again. Despite my
embarrassment, I found I was happy for Abby that she'd found a
friend she could be close to.
