This is an account of my experience with the step sister that came into my home for a short period.
My step sister,
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 had been looking at some porn with my shorts off and stroking my cock.
Joni was down stairs watching tv.
Normally I am able to hear anyone walking around the house however I didn’t hear her come upstairs, my door wasn’t fully closed it was just
A sliver of a gap.
All of the sudden 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.
She walked past into her room and I felt relieved that maybe she didn’t see anything. A few minutes later I saw her sneak up to my door, she was watching me.
I had covered myself at first however when I saw her watching I pretended to not see her and began jerking off slowly giving her a show.
When finally I came she had pushed open the door to see close up.
All of the sudden she went to her room while beckoning me to follow.
She closed her door like mine was and had me standing outside of her room while she put on her own show for me.
We repeated this a couple of more
times over the next few weeks.
It got to the point where we were jerking off for each other in the same room,
we began to fool around and got into
more serious sexual play.
One day my stepfather caught us naked and in bed together.
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.
He spanked her for a long time and to
point that she was in tears. I knew she was in for it when I heard the sound of his razor strop (I still have that strop) hitting her bottom.
Then there was silence and I knew that 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.
When he was done I was in tears and my bottom was filled with angry red welts.
The next day Joni and I were alone
for a short while and we compared our “battle scars”. Her bottom looked like mine, red as a beet and marked with raised welts and marks from the strop.
After my Stepfather caught us we knew that we had to be extremely careful if we wanted to play around.
A few days later we had the chance to talk privately about what had happened.
I told Joni about being able to hear her 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 strangley turned me on. And when I was getting my spanking all I was thinking about was how she must have looked like over his knees.
She told me that she felt the same when she heard me getting whipped.
And it had gotten her excited when we compared our scarred bottoms.
I told her that seeing her bottom red and marked had gotten me very excited.
I asked her what was it about the experience that excited her?
Partly she was turned on (afterward) that she had been exposed and helpless in front of both her dad and myself.
And when I was being punished she had
wondered if I was thinking of her being spanked.
I told her that I would have loved to watched her being spanked.
One evening Joni and I were alone when our parents were out, 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 69 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 her first scream, she got into it and it soon became her favorite thing.
So I had just spent a few minutes fucking her ass and a lot more up front (lol) and at her request had her over the arm of the sofa spanking her bottom.
Joni’s bottom was glowing a nice shade of red. Now she tells me that she wanted to be spanked harder. She looked around the room and spoted 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. Yet she kept asking me to continue, I think I landed at least 30 solid hits.
At this point I could see tears in her face
and a solidly blistered bottom, it was at this point she begged me to make her cum. Thrusting my fingers into both her pussy and ass she begged for me to do it harder and harder. When she finally came she collapsed across the arm of the couch her breath coming in heavy gasps of pleasure and pain.
It was at that moment I looked and saw her dad was 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 trouble.
He proceeded to drag Joni and me up to my bedroom, when we got there he pulled her over his lap and proceded to unleash his anger upon her 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 recieve punishment like I had not experienced prior to tonight.
Joni’s bottom was fire engine red from his spanking.
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 Dy life. On the other hand I saw Joni recieve 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.
His spanking of my bottom was much longer and harsher than that of Joni’s.
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.
To add further humiliation to our predicament he ordered Joni to stand next to him and 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.).
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 and 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.
And she did the same to me.
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 was 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.
