Liz


I hadn't seen my sister Liz for about ten years. I was in town visiting for a
few days and she offered to let me stay with her. I was a little anxious as I
rang the bell to her apartment. She opened the door wearing a white bathrobe
and a pink towel around her head.

"I just got out of the shower and was getting ready for bed," she said. "I
wasn't sure you'd get here tonight."

"I got hung up," I said. "Sorry."

"Well come on in," she said. "Make yourself at home."

She turned and walked away. Towards the bathroom, I guessed. Liz had a nice big
ass that jiggled a little as she moved. She was getting close to thirty and was
about nineteen the last time I saw her. She was a big girl. Not fat but 'full
figured'. She had huge firm tits. I noticed that when she answered the door
because one of them was nearly hanging out.

I sat in a chair and momentarily Liz came back into the living room still
wearing the bathrobe but her hair was mostly dry and hanging around her
shoulders. She was beautiful. She sat on the couch and put her feet up on the
coffee table. I just about shit, as I could see all the way up to her ass. She
wasn't wearing anything underneath.

"Can I get you anything?" she said.

"How about a beer?" I answered.

"Sure," she said. "I'll be right back."

She returned with the beer and sat in the same place and, again, put her legs
up on the coffee table. We talked for a couple of hours about the usual things
that people talk about that haven't seen each other for years. After about six
beers we were pretty relaxed and it seemed almost as if we'd never been
separated.

"You ever see Pete?" I asked.

Pete was her ex-husband and a former high school buddy of mine. I'm five years
older than Liz and so was Pete. I can remember our parents flipping out when
they started dating. They'd been divorced for about three years now.

"Don't mention that pencil-dicked bastard!" was Liz' reply.

"Pencil-dicked?" I asked, a little shocked.

"Yea," she answered. "It's about this big," she said, holding her thumb and
forefinger up about four or five inches apart. Me and my friend Shirley went to
a male strip bar a few nights ago and there was this guy that was hung like a
horse," she said, gesturing with her hands about eight inches apart.

I was really feeling the beer and she had been flopping her legs around giving
me a peek at her crotch every now and then over the last couple of hours. So I
was getting a little turned on and decided to see where this conversation would
go.

"You like them big ones?" I asked.

"Never had a real big one," she said. "So I don't really know."

"Too bad," I said.

"Oh yea?" she asked slyly. "How would you know?"

"I wouldn't," I answered. "At least not from a women's point of view."

"Waddya mean by that?" she asked sharply. "You telling me you're gay?"

"No," I laughed. "It's just that I have a pretty big one myself."

"Hahahahahaha," she laughed. "Every guy I've ever met says that."

I smiled and said, "It doesn't matter to me if you believe me or not."

"Let's see it then!" she said, daringly.

"You want me to show you my cock?" I said, surprised.

"Why not?" she answered. "We're both adults."

"But you're my sister!" I said.

"Hey, you're the one bragging about your cock!" she exclaimed. "Or were you
just bullshitting?"

I could hardly believe that I was going to show my little sister my cock as I
stood up and undid the top button on my jeans and my fly. "Ok," I said to Liz.
"Here goes."

As I pulled my member out I could see her jaw drop. Then she put her hands over
her face and shrieked, "Oh my God, It's huge!"

I was feeling rather proud of myself as I stood there holding my cock at the
base with my thumb and forefinger as it dangled for her to see. My cock is an
honest eight inches long when soft, and a good inch and a half in diameter. I
could see that she was impressed.

After she stopped giggling nervously she said, coyly, "Can you make it hard? I
want to see how big it gets."

I walked over to the couch, waived my dick at her, and said, "Here, you make it
hard."

"Forget it!" she exclaimed. "I'm not touching your dick!"

"Ok," I said. "Suit yourself, I'm going to have a shower and get ready for
bed."

As I headed for the shower I was trying to figure a way to explain my actions.
My sister must think I'm some kind of pervert for asking her to touch my cock.
I got out of the shower and put on my own bathrobe. I had made up my mind to
just act like nothing happened.

As I passed through the kitchen I shouted, "I'm gonna have another beer," then
asked, "you want one?"

"Ok," she replied.

I went back into the living room and handed her the beer. As I turned to go sit
in the chair she grabbed my arm and said, "Sit next to me, I'm not going to
bite you."

I sat close to her, sipping my beer. Neither of us said anything for several
minutes. I was embarrassed at what I had done and I figured Liz was running it
through her mind wondering how to tell me what a low life I was for asking her
to do such a thing.

Liz finally broke the silence. All she said was, "Aw fuck it."

With that she reached under my robe. She wrapped her hand around my cock and
said "I really want to see this thing when it's angry."

I thought I was dreaming. Her hand felt fantastic as she stroked my cock. A few
moments passed. I was completely hard but Liz continued to stroke me. She
pushed my robe aside to get a better look at the full twelve inches in her
hand. She put her head on my shoulder and whispered, "It's gorgeous, I've never
seen such a beautiful cock."

I slid my hand under her robe and cupped one of her breasts. I gently kissed
her neck just below her ear and whispered, "Take off your robe."

Before she could answer my hand traveled down between her thighs. I began
caressing her inner thigh with my hand and slowly worked toward her vagina.

After a short silence she whispered, "Why do you want me to take off my robe?"

All this time she was still stroking my cock. She'd push her hand to the base
then pull toward her till she reached the head. Slowly, almost lovingly. "I
want to see you naked," I finally answered.

As she removed her robe I got up and moved the coffee table away from the couch
so she could lay down. As she lay there I looked her up and down. Her breasts
were still pretty firm with areolas nearly three inches across with hard
nipples as thick as my thumb. Her skin was smooth as silk without a single
blemish that I could see. She had a slight belly that was soft to the touch.
Her hips and thighs were on the large side Just the way I like them. Here I was
looking at what, for me, was the perfect woman and she had to be my sister!

As I took one of her nipples into my mouth she placed her hand on the back of
my head and moaned quietly as she ran her fingers through my hair. As I reached
between her legs to spread them apart she said, "We gotta stop."

I removed my lips from her breast. As I planted a kiss on her lips I guided her
hand back to my cock and whispered, "I want to fuck you."

She was stroking my cock with much more fervor now and her legs lay still
spread. Her breathing was heavy and I knew she was as horny as I was.

"I don't know," she said. "It's wrong."

I knew it was wrong. I had never in my wildest dreams imagined fucking my own
sister. But now I wanted to. More than I had ever wanted to fuck anyone. I
wanted to fuck my sister!

"I know it's wrong," I said. "But you're the most beautiful woman I've ever
seen and I've never wanted to fuck anyone as much as I want to fuck you. If
you're worried about getting pregnant I promise I won't come in you," I
continued. "All I want to do is to feel myself inside you even if it's only for
a few seconds."

"You don't have to worry about getting me pregnant," she sighed. "I can't have
children."

She then lowered her head over the edge of the couch and took the head of my
cock into her mouth. She caressed the shaft with her lips while working her
tongue around the head. After a few seconds she spread her legs wide with her
knees in the air and said, "Ok big brother, fuck me."

I positioned myself between her outstretched legs. I could smell her juices. As
I rubbed the head of my cock in her crack I could tell she was ready. She was
slippery as hell. So I just shoved as much of my cock as I could into her and
fucked her as hard and as fast as I could. I was so damned horny that I blew my
load after just a few strokes. I collapsed on top of Liz.

After a few moments she asked me to get off. I slid off onto the floor with my
back against the couch.

"My back hurts," she said.

"Turn over," I said. "I'll give you a massage."

She rolled over onto her stomach. I started massaging her neck. She reached out
and grabbed my still hard cock.

"It looks like it's still hungry," she said, as she stroked it.

I said, "Why don't you get down here on the floor?" I continued. "It would be
easier for me to rub your back."

"Why don't we go in the bedroom?" she asked.

On the bed I straddled her and began rubbing her back. Starting at the
shoulders and working my way down toward her waist. I worked my way down to her
buttocks and as I massaged her ass I could see the little brown button nestled
down between the cheeks. I positioned myself so that my head was directly above
her ass and I let my hand slip into her crack and as my finger gently touched
her asshole she expressed her approval.

"Mmmmmmm, I like that," she said, lifting her ass toward me.

I removed my hand from the crack of Liz' ass. I kissed each cheek and with both
hands on her ass I used my thumbs to spread her open. As the tip of my tongue
made contact with her anus she squealed with delight. I started making circular
motions with my tongue, licking her crack then probing her hole with my tongue.
She was going crazy with lust.

I pushed her legs apart and kneeled behind her. I knew there was now way I
could get my thick cock in her ass without really hurting her. I just wanted to
put it in her crack and press the head against her anal opening.

As she gyrated her hips in time with my dry humping her ass, she said, "You can
try sticking it in if you want to."

"Have you ever been fucked there before?" I asked.

"No," she answered. "But I've read some articles that said if you do it right
it doesn't hurt much."

"Do you have any thing to lubricate it with?" I asked.

"There's a tube of gel in the drawer," she replied.

I got the gel out of the dresser. I knelt behind her and squirted a generous
amount onto her anus as I held her cheeks apart with my thumb. I inserted my
index finger into her and began to move it in a circular motion while pulling
against the walls to loosen her up. After a few moments I put some more lube on
her ass and inserted my index and middle fingers. I turned my two fingers
inside her and could feel her loosening up. I pulled my fingers out and
positioned my self behind her. I lubed up the head of my cock and pressed it
against the entrance.

As I began to apply pressure she pushed back as if to assist me. The head
slowly moved into her. I was so excited at seeing, and feeling my giant
cockhead sliding into my sister's ass that I thought I'd come right there.

"Uuunghhh," she moaned, as the last of my cockhead disappeared into her
asshole.

With a sudden 'pop' the head was in and I could feel her sphincter tightly
gripping the shaft.

"Wait, stop," she moaned. "Let me get used to it for a second."

I waited for a moment, barely able to control myself. After a while Liz
clenched her ass squeezing the shaft of my cock. Relaxed, then clenched again.

It felt fantastic. After she relaxed the second time she said, "Ok, go ahead."

I slowly pushed the length of my long, thick cock into her asshole until my
pelvis was against her ass cheeks. I pulled all the way out until just the head
remained, then I pushed back into her. Faster this time. I pressed into her.
All she did was moan in pleasure. I was now sure that she was enjoying herself
and that I wouldn't hurt her so I began to fuck her hard and fast.

Liz squealed in ecstasy and shivered. I knew she was coming. I wasn't far
behind as I shot my load deep into her ass.

As I pulled my now semi-soft cock out or her ass, Liz exclaimed, "I can't
believe we just did that."

"Neither can I," I answered.

As we lay next to each other naked, hugging like lovers, Liz said, "I guess
this takes the trouble out of the sleeping arrangements."

"Yep," I replied.

We spent the next few days sleeping together and enjoying each other's bodies.
Eventually we relocated to a town out west where no one knows us so we could
live together. Our sex lives have never been better.
