Hi everyone, my name is Steve, I am currently 20 year old and the following story is my introduction to CFNM by my sister when I was only 11 years old. I didn’t call it CFNM back then, I just knew it as “being naked in front of my sister”.

My parents were very modest about nudity around the house, except when it came to me being naked. I hadn’t seen anyone naked since I was a toddler but both my mom, dad and sister seen me almost daily whenever I took a shower. I guess it was because I was the youngest of the family and the notion that ‘it is OK for girls to see boys’ , that gave my sister the freedom to walk in on me whenever I took a shower and see me in all my glory. We lived in a small 3 bedroom house with only 1 restroom, which made things worse because all 4 of us had to use the same restroom. That meant I was forced to leave the restroom door open whenever I took a shower and either my mom or sister would come in and do their hair and such.

In all honesty I didn’t mind my family to see me naked all the time, after all I had grown up naked around them and my sister had grown up watching me naked so I though she didn’t think anything about. It wasn’t problematic until I hit puberty and I started feeling more self conscious about myself. I was already 11 and my mother still insisted on me leaving the door open. Again either my mom, dad or sister would come in whenever I took a shower and they could see me naked.

I’m sure you all want to know about my sister. She was 6 years older than me and so when I hit puberty she was fully developed. She was the reason of many of my masturbation sessions. She was the closest girl to me and she was also very good looking. I never thought about having sex with her, I just thought about her body and masturbated fantasizing about it. She is a natural blonde but she’s been dyeing her hair red since she was 12. She has white skin and is a bit on the short side of things. What I did notice about her is that her breasts were bigger than average and though I had never seen them, I could make out the shape of her round nipples. Her butt wasn’t the biggest but it was very roundly shaped, as proven by the so called ‘booty-shorts’ that she wore during summer. I had never seen her naked, the most I’ve seen of her is when she would wake up in a sports bra and the tight cotton shorts and she would walk around the house like that. I would always try to get a peek whenever she would bend over and that pose would be the many fantasies of my masturbatory sessions.

Well it all took a turn for the worse or best; depending on how you look at it. It was in the summer of 99 that she caught me masturbating in my bedroom. I had come home from school and I was really horny for a girl that I really liked in school. Her name was Heather and she was a really good looking girl, that day she had worn a pair of short shorts and I stared at her legs whenever I could in class. So I got home that day and there was no one home as usual. My parents got home late from work and my sister got home about two hours later because of her tennis training.

I went to my room and started watching TV in hopes of watching cute girls. I had a bit of luck when I came across a travel channel that was showing the best beaches or something and sometimes they would show girls in bikini. So I pulled down my shorts and started stroking my penis, I had already had my first orgasm a few weeks before and masturbated almost daily since then. I also had a bit of a patch of hair just above my penis. I kept stroking and stroking and all of a sudden the door opened and saw my sister standing right there in her white tennis outfit. I tried to cover with the pair of shorts but it was useless as she had already seen what I was doing. She started laughing and I was embarrassed. I told her to get out but she just stood there laughing. I felt like crying but I was not going to give her the satisfaction so I just stood there. She came closer to me with her hand over her face still laughing and asked me what I was doing. I told her I wasn’t doing anything and she just said “oh really? So what’s this then?” she said as she yanked my shorts from the top of my crotch and now my small erect penis was hanging out in front of her. My first reaction was to cover it with my hands and turn away from her with my bare butt facing her.
“So you were masturbating huh?” She asked in a more serious tone
“No! go away and leave me alone!” I told her but she wouldn’t move.
“Well well, when my mom finds out you’re going to be in big trouble.”

I was even closer to crying because I knew that if my mom found out I had been masturbating she would have certainly killed me. I begged my sister to please not say anything in a high pitched voice.
“Hmmm…” she whispered and there was a moment of silence
“Well I’ll make you a deal, if you’re nice to me and do exactly what I say as I say it I won’t tell mom about your dirty things” she said.
“OK” I said.
“Look at me and say you’ll promise to do exactly as I say and that you’re going to be nice to me.” she said
I was still afraid and wanting to cry but I somehow swallowed it and turn my face towards her while still holding my cock.
“I promise.” I told her.
“OK good, now for your first task I want you to face up and take your hands off your thing” She said.

I didn’t know what to say or think. I was afraid and embarrassed and she was basically asking to expose my privates in front of her. I didn’t want her to tell mom so I did as she told me and faced up and took my hands of my now flaccid cock. I looked at her and she was staring directly at my cock.

“OK good,” she said. “Now, answer my question: were you masturbating?”
“Yes” I whispered to her
“Why were you masturbating?” she asked.
“Because of this girl at school.” I whispered again almost shaking.
“OK show me how you masturbate” She demanded
“What? No I.. I don’t….” I tried to protest.

My sister went to the TV and turned it off. She put both her hands on her waist and said:

“Now you and I just had a deal, if you do as I say you won’t be in trouble, if you don’t then I’m going to tell mom you were masturbating and I’m sure you’re going to be in deep shit. So you better do as I say. SHOW.ME.NOW”

I was stunned that my sister was asking such a thing but I really had no choice. So I took my right hand and started stroking my soft penis. She was standing by my feet so she had a full view of me and I had a full view of her in her white skirt and tight blouse. It didn’t take long before my cock was fully erect and I started stroking it trying not to look at my sister. I tried to forget she was in the room but no matter how hard I tried I knew she was there, staring at my tiny penis watching me masturbate. However, two and a half minutes later I started becoming more comfortable and somewhat turned the tables on her by closing my eyes and thinking about her in her short shorts and sports bra. It didn’t take long before I was ejaculating all over myself and had my orgasm right in front of my sister.

“See it wasn’t that hard now was it? Now remember you be nice to me and do as I tell you and everything will be ok otherwise you’ll be dealing with my mom.” And she left the room.

I was of course very embarrassed but somewhat aroused that my sister had seen me masturbate and she seemed to get a kick out of it. I just put my shorts on and tried to forget about what had just happened.
A couple of hours later I heard my parents come home and I was still in my room. Both of them came to my room and said hi and said hi without making eye contact. About half an hour later my mom called me to ask if I had taken a shower already. I told her no and she told me to go take a shower right away to be ready for dinner. My sister was preparing the table and she gave me this evil smile and I just looked away.
So I stepped into the restroom, took my clothes off and started showering. About 15 minutes later my sister walks in and says that I need to hurry up because dinner is about to be ready so I turned off the water. She steps out the restroom for a few seconds to check to see if my parents were busy in the kitchen. She came back in and she peeked her head inside the shower and stares down at my cock for a second and says to remember the deal that we had. I just shook my head up and down in affirmation. Then she tells me that she it’s not going to be the last time she’s going make me do that and I just told her OK.

I dressed up and headed to the kitchen and sat down without staring at my sister because it was still awkward and my mom told us that Friday night she and my dad were going out and wouldn’t be back until midnight . She instructed us that my sister was in charge and that none of us could go out that night. I saw my sister and she gave me this evil-flirty smile and I couldn’t begin to imagine the shit she was going to put me through. She then asked if she could have her friend Janice come over and spend the night. My parents didn’t object and I knew I was screwed Friday night.
When I was done eating I went to the sofa and started watching tv. My sister took a shower and saw she was doning the very outfit that made me horny, her sports bra and the booty shorts. She sat on the other side of the sofa and told me to give her the remote. I was pissed but I knew I had no choice. My parents went to bed and told us not to stay up past 11 and me and my sister were left in the living room. She muted the TV and got closer to me.
“OK listen go to your room and wait for me there. Go now” She whispered in a serious tone.
No choice, I did as she said and laid on my bed watching TV. A few minutes later I hear the door open slowly and there she was coming in. She closed the door and turned on the lights.

“OK let me see you do it again” She said.

I thought about being embarrassed but there was no point in being embarrassed now, she had seen me stroke my cock a few hours before and there was nothing to hide now. I just took off my clothes and laid naked on top of the bed stroking my cock again thinking about her. I saw her face for a second and her eyes were glued on my cock. Three minutes later and I was cumming all over the bed again. My sister just walked away and went to her room.
At this point I knew my sister wasn’t being mean at all, she was just a horny little brat just like me and got a kick out of watching my cock. To be honest I also got a kick out of showing my cock to my sister and did wanted to keep doing this. Little did I know this was going to be the beginning of a life of exhibitionism, voyeurism, cfnm and some would even say incest.
