MY STEP SISTER
This is an account of my experience with the step sister
who came into my home for a short period.
After my mom remarried I had a new step sister her name was Joni.
We were the same age, both of us were 18 at the time.
One night when our parents were out for the night I was up in my room and watching porn.
My shorts were off and I was stroking my cock to it’s full hardness.
Joni was down stairs watching TV.
Normally I am able to hear anyone walking around the house however today I was so engrossed in what I was doing I failed to hear her come up the stairs.
I had neglected to close my door fully, there was just a sliver of a gap.
Suddenly I was aware of Joni walking past the door.
I hurriedly attempted to cover myself but it was to late she had seen what I was doing.
As she walked past into her room and I felt relieved thinking maybe she didn’t see anything.
A few minutes later I heard her sneak up to my door and peek through the gap watching me.
I had covered myself at first, although when I saw her watching I took a chance and pretended to not see her and began jerking off slowly giving her a show.
I took my time and began to stroke my cock with long slow motions.
Occasionally concentrating on just teasing the head with my fingertips.
The idea that I was putting on a show for someone let alone my stepsister was having a profound effect upon me.
What before was just getting off to the porn had become an attempt to make Joni excited.
Who knew she was such a perv, come to think of it who knew I was one to.
As I rounded the corner to blasting off I began to overdo the sounds I would normally make.
As I got closer to cumming my legs began to shake and my hips started bucking up and down as I thrust my cock through my greased up fingers.
When finally I came the results were massive, my hips bucked and my legs stiffened and the cum came rushing out at mach 3.
This was way past my normal reaction, I could only chalk it up to doing something that was considered such a taboo.
The output was such that my chest and groin were covered with cum.
As I grabbed my shorts to clean up Joni pushed open the door and pretending to be surprised at what she caught me doing.
I in turn pretended to be embarrassed at her catching me doing what I was doing.
She stood there a moment staring at my cock covered with and dripping cum from the head.
Suddenly she turned around and with quick look over her shoulder at my cock she left and went to her room while beckoning me to follow.
Jumping out of bed I didn’t even bother to put my shorts back on, I just went after her.
As she entered her room she closed her door leaving me out in the hallway.
Like mine she left her door ajar and had me standing outside of her room while she put on her own show for me.
Stripping off her clothes in as sexy of a striptease as I had ever seen, she lay back on her bed spread her legs and began to play with her tits, pussy and ass.
At first she spent time running her fingers around the outside of her pussy.
Occasionally reaching under to tease her little bottom hole.
When she finally got down to business she reached under her bed a produced a dildo that she put to use almost immediately.
For the next ten minutes I watched with the utmost fascination as Joni brought herself over and over again to the brink until finally she went into orgasm land.
As she began to come down I slipped away and returned to my room.
We repeated this game a number of times over the next few weeks.
One day I took matters into my own hands (So to speak).
This day as she entered her room I pushed open the door and jumped onto her bed while yanking down my shorts and began to jerk my cock in front of her.
At first she was startled at this bold intrusion.
This lasted only a second or two.
As she sat at her desk I put on my show for her in person.
Thus began our sexual adventures.
We began jerking off for each other while lying in bed together.
One day Joni asked me if she could be the one to jerk me off.
Being the gentleman I am I returned the favor
As the days went on we began to get into more serious sexual play.
We would trade, first Joni would suck my cock and I would return the favor by eating her pussy until I could make her scream with joy.
In the weeks that followed we kept upping the ante until the day Joni said I’m super horny and need a good fucking.
So it was my stepsister who took my virginity and I hers.
Placing my cock at the entrance of her pussy I asked if she was sure she wanted to do this.
In response she told me to shut up and fuck her.
As I began the process of fucking her I began the slow process of opening her pussy up to allow my cock to enter her tight pussy.
Once in I finally understood what all the fuss was about.
This was heaven, never in my life had I felt anything like this moment.
My cock was surrounded by an incredible warmth and held fast by Joni’s muscles.
Those same muscles began to move in such a way that I felt I was being milked.
In to short a time I was ready to cum.
Telling Joni about my impending release she had me pull out and shoot upon her stomach while she drove herself to her own climax.
Two days later Joni told me she had begun taking “The pill” so we no longer needed to be overly cautious.
With that revelation we spent the next couple of weeks fucking like rabbits.
There came the day when my stepfather caught us naked and in bed together.
Joni was on top and riding me like an animal in heat.
We were in the midst of our loving when my bedroom door flew open and her father was standing there his face a bright crimson red and a huffing sound emanating from deep within his chest
“What the fuck is going on here!!!” He bellowed.
Stomping into my room he dragged her naked to her bedroom and through the wall I could hear her struggling and pleading with him as he began to spank her.
I slipped into the hallway and peeked through the door to her room.
Joni was naked over his knees and his hand was on it’s way down when I first looked through the door.
I began counting the blows he delivered to her bottom.
At fifteen you could see her bottom begin to turn cherry red at twenty five his hand prints were clearly viable across her bottom.
This spanking took a long time and to point that she was in tears.
Standing up he dumped her face down on her bed as she continued to sob.
I knew she was in for it when I saw him pull off his belt.
He began stroking her bottom with the belt.
It was at this point her sobs morphed into screams of pain and humiliation.
After fifteen strokes he turned and began to leave her room.
Only by the skin of my teeth did I make it back to my room before he came for me.
I knew that now it was my turn.
I had by that time put my shorts back on.
He came into my room ripped my shorts off and dragged me over his knees.
Delivering to me the same spanking that his daughter just received only worse.
He kept at it for a much longer time with me.
His hand rose and fell like a machine, over and over the crack of flesh upon flesh makes it’s own unique sound.
When he switched to his belt I felt that my bottom as well as my soul was afire.
The entire time my punishment was being delivered I was thinking of Joni and how her bottom looked after he was finished.
When he was done I was in tears and my bottom was filled with angry red welts.
The next day Joni and I were left alone for a short while and had the chance to compared our “battle scars”.
Her bottom looked a lot like mine, red as a beet and marked with raised welts and marks from his belt.
After having been caught we knew that we had to be extremely careful if we wanted to play around.
It was days later we finally had the chance to talk privately about what had happened.
I told Joni that I stood outside her door as she was being punished.
That I was able to hear her struggling and pleading with him to stop.
I told her that seeing her dragged naked by her dad to her room had strangely turned me on.
While I was getting my bottom beat all I was thinking about was how she looked while she was over his knees.
She told me that she felt the same when she heard me getting whipped.
How it had gotten her excited when we compared our scarred bottoms.
I confessed to her that seeing her bottom red and marked had gotten me turned on and very excited.
I asked her what was it about the experience that excited her?
After a few minutes of silence Joni opened up and told me she was turned on (afterward) that she had been exposed and helpless in front of both her dad and myself.
When I was being punished she had wondered if I was thinking of her being spanked.
I told her that while I was horrified to witness her punishment, when it was my turn all I could think of was her.
One evening when our parents were out Joni and I were finally alone, we were fooling around in the rec room both of us teasing each other about the things we had done and the chances we took.
We had spent the last 30 min. giving each other oral sex sometimes in a sixty-nine position and other times just switching.
For Joni, anal was the thing that got her the hottest.
The first time she tried it she was reluctant however after the initial pain, she got into it and soon became one of her favorite things.
So I had just spent a few minutes fucking her ass and a lot more up front.
Stopping me in mid-stroke Joni asked me to do something that frankly surprised me.
She bent herself over the arm of the sofa and told me to spank and belt her bottom.
As the surprise wore off I asked if she was sure, when she nodded her affirmation I began.
I ran my hands over her ass feeling the welts that were beginning to fade, left there by her father.
Reaching back I felt the welts left behind on my bottom and instantly understood what Joni wanted.
They were a stark reminder of what we had undergone, what we had shared.
As my hand came down the first stroke landed squarely across both cheeks.
From Joni there was a quick sharp intake of breath followed by a release of breath that could only be described as one of relief.
Each of the following strokes brought forth moans along with Joni trying to keep control of her breathing.
While I was doing my best to keep the spanking to a moderate level Joni suddenly said “Harder”.
OK I began to lean into what I was doing and my hand began to flash through the air as I delivered a series of fifteen blows to her bottom.
Stopping for a moment I told her to catch her breath for a moment.
While she was doing this I walked over to the closet and took down a wide leather belt.
Returning to Joni I doubled over the belt and while I did this I snapped the belt together creating a sound that brought a gasp from deep in Joni’s throat along with a tiny whimper.
The first hit from the belt landed upon her left cheek causing her to clinch her cheeks tightly.
At the second hit she began groaning.
Stroke number five and Joni was trying to dodge the blows, yet never once asking me to stop.
Stroke ten brought tears to her eyes and the redness of her bottom had morphed to a bright crimson
and the marks from the edges of the belt were clearly defined.
Tomorrow these were going to be raised and angry looking.
She looked around the room and spotted her dad’s fraternity paddle hanging on the wall.
As I followed her gaze I sensed her desire to feel it’s sting.
Retrieving the paddle I saw a look in her eyes akin to fear.
As I swung the paddle you could hear the whooshing of air just prior to it landing on her bottom.
When it struck home she let out a shreak of pain.
I became hesitant about continuing but Joni said to keep going and not to stop until she asked me to stop.
Moving the paddles aim so as not to hit the same spot twice in a row, I covered her bottom with marks and welts that would take days to heal.
At this point I could see tears in her face and a solidly blistered bottom.
Stopping my assault I moved closer to Joni and rubbed some hand lotion onto her bottom to sooth the burning.
Taking a step further I placed some of the lotion down the crack of her ass and began to work it into her little hole.
Without warning I stepped behind her and rammed my engorged cock into her tight bottom.
Immediately she let out a scream while at the same time pushing back to meet my thrusts.
For the next few minutes I pounded Joni’s bottom as she wailed up a storm.
When I was about to blow I reached under Joni and furiously rubbed her clit.
In just second Joni began her orgasm.
As this took place her little hole began to spasm, milking my cock as I tried to ride out the wave of her orgasm.
This triggered my climax and I began pumping tons of cum into Joni’s ass.
As I fell away from Joni her orgasm began to subside, leaving her gasping for breath.
Gathering myself I crawled over to her and held her in a tight embrace while reassuring her how much I loved her.
It was at that moment I looked behind me at the door and saw her dad watching us from the hallway.
How long he had been standing there I don’t know but it was long enough to clearly see what we were doing.
Joni’s dad had come home earlier than we expected.
My mom decided to stay overnight at her friends place and he had come home to check on us and inform us that they would be home in the morning.
He had seen what we we’re doing and had watched practically the whole thing. As he came into the room we knew that we were in deep trouble.
He proceeded to drag Joni and me up to my bedroom, when we got there he pulled her over his lap and preceded to unleash his anger upon her already tortured bare ass.
Joni was in tears and begging for me to help and for him to stop.
I was frozen with fear and I have to admit lust.
To watch this unfold before my eyes had me rooted to the spot.
He was brutal in his assault upon her bottom.
It quickly dawned on me that I was going to receive punishment like I had not experienced prior to tonight.
Joni’s bottom was fire engine red from his beating and the spanking I had administered just moments before.
I had extremely mixed emotions about what I had witnessed, on the one hand I knew that I was going to get the beating of my life.
On the other hand I saw Joni receive the spanking of the decade and I wanted to stop him, yet I stood there and watched.
When he had just about ended her spanking he took his fingers and jabbed them hard into her pussy saying “Is this where Frank put his little pecker?”
“Did it feel like this?”
As he jabbed them in her a couple of times so hard that she screamed.
When he was finished with her he stood her up and had her stand there to witness my discipline being administered.
Tossing me over his lap he set his mind to the task of impressing his hand print permanently upon my ass.
The beating of my bottom was much longer and harsher than that of Joni’s.
Blow after blow pummeled my cheeks each burning hotter then the one before.
After a few minutes I started trying to dodge the blows but he managed to get his leg over mine to keep me in place so I was unable to escape his wrath.
Shoving me off his lap he pushed my face into the mattress while picking up the belt I had used earlier on Joni’s bottom.
Now his beating took on an air of domination.
As I tried again to dodge the blows he ordered Joni to kneel at my feet and hold my legs still while he concentrated on the belt in his hands.
When he had had enough he stood back to admire his handy work.
To add further humiliation to our predicament he ordered Joni to stand up next to him take the fraternity paddle and had her hit my bottom with it.
At first her blows were restrained but he told her if she didn’t do it harder he would use the paddle upon her.
He was not in control, his emotions were (And I came later to believe that there was an incest type of lust in his subconscious.).
Stopping Joni in mid swing he said to me,
“Do you like fucking my daughter in the ass, did that get you off?
Let me show you what that must have felt like to my daughter.”
With that I felt him move between my leg and as I looked behind me I saw that his pants were down and his cock was raging red and dripping with pre-cum.
Grasping both my cheeks he spread them wide and in a single thrust jammed his cock into my ass.
My response was to groan in fear as he ravaged my bottom.
He only lasted about ten or fifteen strokes before he emptied himself into my bottom.
I was acutely aware of Joni’s presence in the room watching and being forced to participate in this exercise of control and what her dad was doing to me.
The thought that she was present and watching mitigated the pain and humiliation I was going through.
This allowed me to hold out for longer than I believed possible.
In the end we both suffered yet survived the ordeal.
When he was done he left saying that he would see us tomorrow.
When he left, Joni and I went to my room and fell asleep in each others arms.
We awoke in the middle of the night and we started talking about what had happened.
I turned her turn over and pulled down her underwear to inspect what damage had been done to her bottom.
I reached over to the nightstand and took the bottle of hand lotion and began to rub it into her bottom hoping to relieve some of the pain that lingered.
Turning me face down Joni pulled down my shorts and began to rub lotion into my bottom.
The feeling of her hands rubbing and working the cheeks of my bottom began to turn me on.
Turning to face her we began kissing, this in turn led us to another round of making love.
We began in a sixty-nine position.
Eating Joni’s pussy was the greatest treat I could think of.
Every now and then I would grasp her bottom and squeeze, resulting in a squeal of pain and joy.
When she returned the favor I felt my cock harden even more.
We ended up making love for the next couple of hours before we went back to bed.
We were surprised that he never said anything about what had happened to my mom.
When our folks came back the next morning not a word said about what happened the night before.
Two weeks later he left my mom and took Joni with him.
That was the last time I saw him or Joni again. I found out a couple of days later that he has served my mom with divorce papers.
