Caught Masturbating by my Sister (incest, straight)

Rod Weilder's sex story
There's probably not many things more embarrassing and humiliating than getting caught masturbating by your sister. Especially for a 17-year-old boy getting caught jacking off by his 15-year-old sister when she's having a slumber party with 5 other girls!



My sweet little sister. Boy, do we have some wild memories together. Some good, some bad, and some that can only be described in stories like this one. This is the story of me being caught jacking off by my sister when I was 17 and she was 15, and it was right outside of her bedroom door when she was having a slumber party with five of her closest girlfriends.

First of all, let me give you a little of my family history. I lost my mom to breast cancer when I was five and Stephanie was three. I was right around my mid twenties before I could even really talk about it, and I'm 45 now. It's funny sometimes how time is the only thing in the world that can heal certain things, or at least make them better. Anyway, then we lost our dad in a construction accident when I was 13. I guess Steph and I have been through a lot, but I know we aren't alone. We both believe there is something beyond this life we are in now, there has to be, but that is a whole other story that has no part of this one.

My dad had remarried when I was 10 to a woman named Elizabeth, a woman I'm still very close to to this day. I suppose it was maybe a little odd, but when dad first married Elizabeth, I was 10, Elizabeth was 20 and dad was 30. Even though Elizabeth is my step-mom, I have always just called her my mom, well, since I was 14 or so. It was easy to get close to Elizabeth right from the start, but it naturally took some time before I was ready to call her 'mom'. After I lost my dad, well, mom and I became tremendously closer in so many ways.

Now back to the mind-blowing night of Steph's slumber party. Stephanie was a cheerleader all through junior high and high school, but she was never really like most of the other cheerleaders. Steph has just always been a lot more approachable and very friendly toward one and all, not just toward some and not others. Of her five special friends that night, two of them were on the cheerleading squad with her - Tina and Brenda. In the cuteness department, they were both right up there on the same level with my beautiful sister. They were also right up there with Steph in the sweet and wonderful department. There were nine other cheerleaders on their squad, and it was no big secret that they were jealous of Steph and Tina and Brenda. I was so very proud of my baby sister for not being like the other cheerleaders, and for choosing friends like Tina and Brenda.

That certainly included Stephanie's other adorable friends that evening - Molly, Jamie and Annette. I don't know why they weren't cheerleaders, too. They were every bit as pretty and as athletic as the other cheerleaders. Molly and Jamie were on the track team and Annette was on the girl's basketball team. But it was definitely the pretty smiles, the beautiful eyes, the gorgeous hair, the small but developing breasts and the adorable butts on all six girls that I was interested in on slumber party night.

I was in my bedroom doing my math homework in nothing but my underwear. It was all the homework I had and I would be free for the weekend. Mom was out on a date and would be out until late. I heard the girls laughing really hard and it just kept going on and on. Soon I really started to wonder what they could be laughing at. I slipped out of my room and quietly crept up to my sister's door. I was going to peek through the keyhole and then I noticed the door was cracked open a bit. I squatted down and gently pushed the door open a little further.I saw a quick flash of Annette go by and it looked like she was naked! I looked closer and inched the door open wider. She WAS naked!
I saw Brenda naked, too! The girls were having a pillow fight! I saw a quick flash of Brenda again and saw her jiggling boobs, then I saw Jamie and her jiggling butt cheeks and saw that she too was completely naked! My dick had already started getting hard before I even stepped out of my bedroom, and I slipped out of my underwear and tossed them into my bedroom . I wanted to feel the freedom and excitement of being totally naked right outside my sister's door. I began stroking my cock and peeking through the door again. This time I saw Tina fall in the floor in shrieking laughter with her gorgeous legs spread wide apart! I couldn't believe I was seeing Tina's pussy! Who I really wanted to see naked was my beautiful baby sister as I was jacking off hard now. Well, I definitely got what I wanted, but not quite the way I was expecting it.

'What the fuck are you DOING?' Stephanie shrieked behind me. I jumped and spun around, covering my pink, burning cock with both hands. My little sister was standing there just as naked as the day she was born! She was never in the bedroom the whole time, she must have been in the bathroom.

'Oh, my GOD, Stephanie, you scared the FUCK out of me!' I rasped.

'You didn't answer me. What the fuck are you doing outside my bedroom door naked and why were you tugging on your penis? Why are you hiding it? I've seen your penis before a million times, the way you are always going from the bathroom to your bedroom completely naked after you get out of the shower. I don't know why mom never says anything to you about that.' Steph scolded me.

'That's what I was about to do, I was on my way to take a shower and I thought I heard a scream or something coming from your room. I guess it was just your friends laughing really hard,' I said, still covering myself as I took a quick glance at my sister's thick patch of pussy hair and looked away. One thing was for sure, Stephanie wasn't the least bit shy or concerned about being completely naked in front of me. She was standing in a wide stance with her hands on her pretty hips and her hips cocked way to one side, and she was demanding answers from me .

'You're a LIAR. I already know you took a shower at 8:00, Rod. Try again. And will you quit hiding your penis? Let me see it!' Steph demanded as she stepped up and grabbed my forearms, pulling them apart. I yanked them back together just out of reflex really, but it was only a split second and I totally relaxed and submitted to my breathtakingly beautiful sister. I made the mistake of getting physical with her once. There was no way in hell it was ever going to happen again. Stephanie began speaking even before I relaxed my arms and gave myself up to her.

'Don't you get physical with me, Rod! Don't you dare lift one finger against me, or have you forgotten what happened a couple of years ago when you pushed me and mom hauled off and kicked you right square in the BALLS just as hard as she could kick?' Stephanie reminded me as she held my arms to my sides. We were practically close enough to start kissing, we were both stark naked, and my dick and balls were totally exposed to her.

'No, I haven't forgotten when mom kicked me in the balls in front of you and you busted out laughing when I fell to my knees in the agony of my life in front of you, Stephanie. How can I forget something I'll remember the rest of my life?' I asked, the question falling on deaf ears.


'Why is your penis standing straight up like that? Why were you tugging on it so hard? Were you MASTURBATING outside my door, Rod? Don't you DARE lie to me!' my sister demanded.

'Okay, Stephanie, yes ma'am. I was looking at your pretty friends and I was jacking myself off,' I said flatly.

'WHAT? I can't fucking BELIEVE you!' Stephanie said, stepping forward and driving her sweet knee up into my balls hard. I let out a deep grunt of pain and doubled over, my butt bumping her bedroom door wide open as I staggered backwards into her room. She kept a firm hold on my arms and quickly pulled me toward her while she stepped toward me. She wasn't satisfied with giving me just one knee to the balls, she was going to give me another one!

'Stephanie, PLEASE don't! Stephanie, NO! GUHAWWW!!' I let out a booming grunt of intense pain and dropped to the floor. Molly shrieked and scrambled away from me. I drew my knees up to my chest and just rocked back and forth, my balls could not possibly have been more exposed. It felt like my sweet baby sister had ruptured me right in front of her pretty girlfriends.

'Gross! What the fuck are you DOING, Rod?' said Molly as she bent down , raised her fist and slammed it straight into my badly racked up balls. She couldn't possibly have gotten me any more solidly. I was ready to beg for my life after 3 blows to the balls by two very nice, charming, caring, soft-spoken fifteen-year-old girls. Well, soft-spoken for the most part.

'Stephanie, what the fuck is going ON? Why is he in here with no clothes on?' asked Tina.

'Because I caught him jacking off at my door while he was peeking in at you guys and I busted his balls for it,' Stephanie smiled over me with sweet confidence.

'What? Are you serious?' asked Jamie as she stood over me. I glanced up at her sweet cunt right over my face, then over at Tina's, then Stephanie's, then Annette's. Molly and Brenda stood behind me. Not a single girl was the least bit concerned about her nakedness as they stood over me with their hands on their hips like it was perfectly normal for all of us to be naked in front of each other.

'Oh, I'm totally serious. And you know what? I think I'm going to give him what he wants! I'm going to jack him off! Get his legs spread apart and hold his arms down and out of the way, girls,' said Stephanie, calling the shots with pure female authority.

'Here, get his other leg and hold it down, Annette,' said Tina as the naked girls spread his legs apart and pinned them down. Jamie and Molly held his arms down.

'Stephanie now you really can't be serious. You're going to jack off your own brother?' asked Brenda.

'Sure. I just didn't say HOW I was going to do it to him!' Stephanie said with a girlish giggle. She smiled with sweet satisfaction as she knelt down between his legs and took hold of his cock. He gasped and moaned at the feel of his little sister's sweet touch. 'You know, Rod, mom taught me quite a few things about boys, and there's one thing she taught me very carefully about you. For some reason she felt like you just might ask me to jack you off one day, and if you ever did, she showed me just exactly how she wants me to do it to you. Now, I know you didn't ask me, but since I caught you jacking off while you were looking at my friends, well, I decided I'm going to do it to you right in front of all the pretty girls you like to look at so much. So with all of that being said, I hope this feels good for you!' Stephanie smiled at me.

With that, she slid her knee up under his balls and pushed them up, then she began pumping him up and down hard and fast, really pounding and beating his helpless balls against her knee. He started immediately gasping and twitching and jerking around with the sharp stabs of pain that my adorable baby sister was joyfully causing me. When the other girls saw just what she was doing to me, they began joyfully expressing their approval.

'How's that Rod? That feel good? Hmm? You like that?' Stephanie teased as I really began to jerk and wail and beg. I cried out frantically that Stephanie didn't have the right to do me this way, only our mom had the right and the authority to administer this kind of punishment. She totally stopped what she was doing. I was about ready to start bawling!

'You know what, Rod? It's funny you should mention that. That brings up something else I learned from mom. Mom told me that there are two kinds of people in this world - those with balls hanging down between their legs, and those with TRUE authority! Now, I'd like you to take a look at something,' said Stephanie as she stood up and turned around and squatted just above his face by inches. The girls began snickering and laughing hard. 'Now you take a real close look, big brother, do you see any balls anywhere between my legs?':

'Um, Stephanie, I totally swear I don't mean any disrespect to you, but did you know that you've got your butt just right smack in my face right now? I mean, is that REALLY necessary?' I asked

'Yes, I think so, at least until I make you ejaculate in front of all the girls. I want you to have an orgasm while the only thing you can see is my butt and my pussy,' Stephanie giggled. She resumed with jacking him off hard and fast. He knew he was going to come for her soon, and he just couldn't resist any longer. If he was going to ejaculate by the soft, smooth, dainty, adorable hand of his precious little sister with her incredible cunt practically pressing into his mouth, he was going to take full advantage. He plunged his tongue deep into her silky, wet canal. She squealed and jerked herself away from him.

'Steph, what happened?' asked Tina.

'Oh, nothing, my silly brother just put his tongue inside my vagina,' Stephanie giggled. ' You need to just.......I don't know..........stick it in my butthole or something,' she said as she curiously pressed her wet pussy down on my mouth again. Again I plunged my tongue deep into my sister. This time I heard her moan and she didn't pull away. 'Okay, two can play that little game,' Steph said as she swallowed my cock and started sucking.

'Oh, my God, Steph, what are you DOING?' Molly asked.

'Well, he's doing it to me so I'm gonna do it right back to him!' Steph replied. We both kept sucking until her orgasm triggered mine, and it was one of the most powerful orgasms of my life. I was married for 12 years, and my wife never gave me an orgasm as powerful as the one my sister gave me that day.

I guess that's why I still have sex with my sister to this day, and I'm talking about frequent intercourse, yes. She's on the pill so we really aren't worried about anything. I wish they would let siblings marry because I really don't want anyone else. Steph was also married only once like myself, but her marriage only went for 8 years.

I have sex with my step-mom now and then as well. One note I wanted to mention, two days after my mom kicked me in the balls for pushing Steph, she came into my bedroom and said she wanted to check me down there to make sure she didn't damage me. She kept holding my balls and making me cough, then she would gradually squeeze me harder and harder until I couldn't take it any more. She got me rock-hard doing that, then she suddenly starts jacking me off and telling me that it was all part of the checkup. She had to verify that I could still ejaculate and there's only one way to do that!

On a final note, my mom and sister both have taught me a lot of very valuable lessons about respecting women. One of the simplest and most basic questions a guy can ask himself is this: Is it really that much effort to say 'yes ma'am' and 'no ma'am' to a girl? I don't have any problem at all saying that to my mom or my sister. Are you kidding me? If you're wondering at what age would you begin addressing and responding to a girl that way, that's easy. Is she old enough to speak in sentences? If so, there you go! If a girl just doesn't like to be called that, there are lots of other ways to show respect. Might be good practice for a guy these days. Women may rule the world one day.
