This all started on a bright summer morning.  We live in a suburb outside of a major city and are about 500 yards from out nearest neighbor, not to mention separated by dense tree cover.  Anyway it was a summer morning about 9 am and I was just waking up to an empty house.  Well not entirely empty I am home and so is my younger sister.  My name is Ken and I am 21 years old my sister is Cindy and she is 17.  Little did we know that this was not going to be a normal day of sitting around watching tv and surfing the web like the days before.   I remember it clearly I woke to a tapping that I wasn’t sure I actually heard or imagined.  As I woke the tapping seemed to stop then started again.  I got dressed and went downstairs to investigate the raccoon that was probably in the garbage again.  As I approached the door and unlocked it I looked outside to see no raccoon.  I then walked around back for a better investigation.  As soon as I turned the corner towards the back of the house I felt a strong blow hit my stomach and what seemed to be a handkerchief pulled into my mouth by hands on both sides of my mouth.  As I heard the words muttered “don’t scream or we kill you” whispered in my ear the handkerchief was let go.  I now saw three men who looked like they were from another country but spoke decent English.  One was thin and tall and as I looked he lifted his shirt a bit to reveal a gun he had on him the other two did the same.  The tall one began to explain that I was going to do exactly as he said or else.  They shoved me toward the house and I tried to object, because I knew Cindy was in there.  But eventually their shoves turned into blows and I was forced into the house along with the three intruders.  Once inside the tall one who called himself Manny started to explain to me what was going to happen.  He said “You see we have been stalking your home for about 3 weeks now and we know that no one in your family will be home for at least 7 hours” I asked “Why have you been stalking our house.”  To which he replied “Well about a month ago we were sent here to take care of some business for our leader.”  “What kind of business” I asked.  “Well we needed to make a movie for his collection and then we saw your sister about 3 weeks ago.”  “You leave her out of this, besides she isn’t even here she went on a vacation” I said.  “Ken, my boy we are a lot smarter than you think.  We know your sister is upstairs in her bed sleeping.  Probably wearing nothing more than her pink panties and a tee-shirt.”  Now I lost it and I lunged for the man with the gun.  The other two men subdued me as I was told by Manny.  “Here is the deal Ken you might not care for your own safety, but do you care about you sister’s?  Remember I have a gun and another thing outside you have a nice tree mulcher.  If you don’t listen to everything we say you will not be hurt, but your sister might just fall into the tree mulcher.”  Upon saying that last sentence he shook me violently and he realized he finally had me under control.  He then gave me his word “If you and your sister listen to everything I say no one will get hurt.  If you don’t you know what happens.  Now here is the really fun part for you.  First I want you to act like we are old friends from now on.  If you don’t do that then this is what happens.”  He pulled out his wallet and showed horrible pictures of people who had been killed.  Some were barely recognizable.  And most were females.  “You see these people didn’t listen and if you want Cindy to avoid that listen carefully.”  “Alright anything” I murmured.  “Like I said Cindy is to think at all times that we are your friends and everything that happens is your idea.  You are to go into her room and lay beside her and listen to everything and I mean everything we say.  Not only that you will act as if everything that happens is your idea.”  “What is going to happen?” I asked.  To which he replied by having one of the men remove a dvd and camcorder on a small tripod from a backpack he had on.  “What is this for” I asked.  He told me I want you to lie in bed next to your sister and copy everything that is done in this video.  If you mess up on something then start over and do it again.  In case you need it, take this” He threw a small handgun to me.  “Don’t bother trying to use it on us, it’s unloaded.”  “What’s it for I asked”  “Use it if your sister doesn’t listen” They also had me run some audio/video wires from the camcorder to the tv in my room so they could watch.  By now I had a really bad feeling about all this, but I didn’t want my sister to wind up like them people in the pictures.  The thought of them pictures made me want to throw up.  And the thought of imagining my sister’s body being shown to the next person in their game sickened me worse.  So I hooked everything up and sheepishly jumped into bed next to my sleeping sister.  I hit play on the dvd to see a guy doing the same thing I was doing.  But this guy looked happy and it looked as if the girl next to him was a lover.  I didn’t like where this was going at all, but I had not choice.  I kept telling myself that I am going to do whatever I have to so that my sister doesn’t become a picture.  The guy immediately removed the sheets from the sleeping girl who was now laying in just her panties and a tee shirt.  Weird coincidence my sister was the same when I removed the blanket.  The guy on the tape began to immediately message the girl’s hips and play with her panty line.  I looked down and my sister was wearing a small pink thong.  I hesitated for a minute and then I heard angry banging from my room.  So I copied the video and I started to play with the string from the front to the back of the thong.  The guy then began to message the girl’s vagina through the panties.  I couldn’t do this and I didn’t.  One of the guys quietly opened the door and with the remote for the dvd player started the video over.  He then told me “Do it all again.”  To which I realized that if I kept messing up two things would happen.  These guys might kill my sister or I would have to keep performing these acts on my sister over and over.  So this time I was determined to just get done whatever I had to, for both our sakes.  So as the tape got to the part where the guy messaged the front of her panties I timidly began to message the front of my sister’s panties.  I knew my sister was a heavy sleeper so I figured she wouldn’t wake, but what did surprise and disgust me was that her panties began to feel damp.  I couldn’t believe this I was actually making my little sister wet.  I wanted to throw up but I had to keep doing whatever the video was doing.  After the girl on the video was nice and wet the guy pulled out some scissors and cut off her panties.  I got scissors from my sister’s desk and did the same.  Then as I watched the guy began to masturbate with the panties he just removed.  So I began to try to copy this.  I was not hard in any way shape or form, so I just started to rub them on myself.  And eventually to my surprise I began to get rock hard.  I was so disgusted with myself that I was getting hard from rubbing my sister’s wet panties on my cock.  So I watched and copied for about 15 minutes as I masturbated with my sister’s panties.  I heard the door slowly creek open and one of the guys said “If you like your little sister’s panties so much maybe you should take a pair out of her hamper and wear them.”  I know he said this just to further my embarrassment and discomfort in this situation.  As I walked over to her hamper I looked in and saw a small thong on top.  I wanted to look for something a little bigger but I heard the banging coming from my room.  I quickly removed all my clothes and put it on.  I could tell it was really dirty because I could feel that the inside was hard as it slid up my legs.  At this point I was totally emasculated and began to watch the video again.  By this time the guy was on top of the girl and was sucking on her nipples.  I jumped onto the bed quickly and my sister began to wake.  This was bad, really bad.  She woke up and looked at me and said “Ken what are you doing?”  I just held her mouth shut showed her the gun and told her to listen.  I could tell she was really scared.  Then she looked at the tv and saw the video and she bagan to freak out.  I held her down for about a minute and she started to tire out a little.  She begged me not to do this to which I replied “Shut up I have no choice.”  I couldn’t even let her know that I too was being forced into this.  I had to make her believe, that as sick as this was I wanted it and it was my idea.  I rolled her onto her stomach and held her down.  I looked at the video of the guy, who was obviously working with a willing participant.  He for some reason was putting panties back on the girl.  I reached around on the floor and found a g-string on the floor.  I first put it around my sister’s feet and then as I was holding her down I began to slide it up her legs.  The girl on the video dressed up like a total whore.  To which I pointed the gun at my sister and told her to copy.  She found a really short mini skit and a tube top.  I didn’t know exactly what was going on, but I knew we should follow the video.  Then I had her copy the video and put on a lot of makeup like the girl in the video.  This made my sister look like a trashy whore.  After the girl was done dressing on the video she began to give the guy a lap dance.  I was so embarrassed and ashamed.  Here I was sitting on my sister’s bed in her thong and I was getting a lap dance by her.  She copied the video and began to pull her skirt up and rub her ass all over my cock.  She then reluctantly pulled down her skirt and took my cock in her hand.  She started to give me a dry hand job.  I was soft because this was my sister but she kept trying.  Eventually I started to get hard from my sister rubbing my balls and stroking my cock.  Once she was down to a bra and g-string I copied the guy in the video as he pulled off the bra and sucked on the nipples of the girl.  My sister was shaking in fear as I did this. Her nipples began to get hard.  She was still doing everything like the video because I still had the gun in my hand.  After the lap dance the guy pushed the girl onto the bed and began pulling the girl’s panties to the side and trying to put it in her ass.  I copied but was having to much difficulty with no lube, as thankfully the guy on the video was.  So as I held my sister and watched the girl on the video turned around and began to give the guy a blow job to lube him up.  I didn’t know how I was going to do this one.  Then I remembered the gun.  I looked for the guy and saw it next to the side table.  I stopped for a minute.  What was I about to do?  I was going to hold and gun to my little sister’s head and tell her to blow me so that I could rape her anally.  Then the pictures began flashing in my head and I heard the banging coming from my room.  This was a signal that I better continue or my sister, unbeknownst to her will suffer.  I grabbed the gun and slowly pointed it at my struggling sister.  At first she freaked then she began to calm down.  I told her to look at the movie and do everything that the girl in the movie was doing or I would have to use the gun.  She got a good look at the video for the first time.  The guy was sitting on the bed and the girl was blowing him and occasionally taking the cock out of her mouth and spitting on it.  It was really real slutty the way she was doing this.  My sister looked over and I was pointing the gun at her and sitting on the bed like the guy in the video.  I could tell she wanted to run.  She didn’t  know it, but if she ran it would be worse then staying.  She got on her knees in front of me and sat at an angle so she could watch the video.  She now realized that I was wearing one of her thongs.  Now she looked more disgusted about what I wearing than about what I was about to make her do.  So looked up at me with tears in her eyes and I felt worse in that moment that I ever thought humanely possible.  With her small hands she began to pull my semi-erect cock from her own thong and masturbate it with her hand.  Against my own will my cock became hard incredibly fast.  She then slowly lowered her lips to it and as I expected her to swallow it she surprised me and spit on it first.  It was a real slow runny spit and she then put the head in her mouth.  As horrible as this site was I had to admit that it felt good, which made me feel all the more worse.  She looked at the video and began to move her warm lips up and down on my cock, then at it was really lubed up she started to use a hand along with her lips just like the video.  After about 3 minutes of an admittedly, great but horrible blow job I was really turned on.  As my sister watched the video she noticed that the girl slipped her hand into her panties and began to masturbate while giving head.  I could tell she didn’t want to do this, so I came back to reality and point the empty gun at her head.  She then slowly slipped her hand down her panties and began to rub herself.  I noticed that she was barely rubbing herself so I reached down and put my hand over her hand from outside her panties and applied pressure.  As I did this my chest was pushing her head on my cock so far that she wound up deep throating me.  But I knew if she didn’t play along right this would all be for nothing.  As I let go be kept rubbing herself and eventually I could see an apparent damp spot in her panties.  After a few more minutes this spot turned from damp to completely wet.  Then the girl on the video began to take her we hand and rub it up and down the guy’s shaft while still blowing him.  My sister didn’t want to do this at all but she realized she had not choice.  The moment she put her hand with her juices on my cock I began to become so aroused that I knew I could no longer stand this. My sister was now against her will giving me head and tasting herself at the same time. The girl on the video was still pumping the man when I began to cum down my sister’s throat.  She was so repulsed that she pulled her mouth off my cock and began to cough on the cum she was choking on.  I pulled her head close so she couldn’t get away and came all over her face.  At this point she was crying and I felt horrible for what I did.  I stood up and held my sister in front of me.  I looked to my side to see myself standing wearing nothing but my sister’s thong and he in front wearing the same.  My cock was still erect and I was so horny from all this that I knew I could keep going.  I was hoping that this video was done and already thinking about how I could possibly explain this to people, let alone my sister.  But I looked over and realized that the video was still going.  Now the man and women were in bed together and they were kissing like lovers while the guy was messaging the girl’s wet pussy with her panties pulled to the side.  So I threw my sister into the bed and began to kiss her, she didn’t kiss back but didn’t fight it either.  I began to rub the outside of her panties and then slowly pulled them to the side.  I noticed she was wet from rubbing herself.  When I realized this I could tell she was really embarrassed because he face was red.  I started to rub her and she parted her legs realizing she didn’t have much choice.  Just then the guy on the video started to insert his fingers into the girl.  So I took my pointer finger and slowly began to insert into my sister.  I went in an in and out motion slowly and she began to respond despite her reluctance.  After I got 3 fingers in her, she instinctively began to buck her hips a bit and soon she was really into it. Within about 10 minutes she was cumming and moaning.  I kept my cum covered fingers in her and watched for a couple minutes as the video caught up with us.  As the girl on the video began to cum the man flipped her on her side and used his cum soaked fingers to lubricate her ass.  I was so disgusted by the thought of taking my sister anally.  My sister was so degraded by this time that she was barely fighting back as I pulled her g-string to the side and began to rub her own cum all over her asshole.  I mirrored the video and instead of loosening her up with a few fingers I aimed my hard cock right toward her anus while watching the video I thrust with all I had an was able to not only penetrate but also get my cock ¾ of the way in.  She screamed in pain and tried to pull away I held her close to me hard.  She began to cry from the pain as I inserted my cock all the way inside her.  I let it sit for about 30 seconds all the way inside so she could get used to the feeling of a cock in her ass.  The man on the video asked the girl if she ever had it in her ass and them he asked her if she felt like a whore having a cock covered in her cum in her ass.  I reluctantly asked my sister “So have you ever had a cock in your ass?”  She didn’t answer so I asked more angrily a second time.  She eventually replied with a weak “no.”  I then asked “Do you feel like a whore having a cock covered with your cum in your ass?”  She replied with a soft “yes.”  The guy in the video replied to the girl “Well you are a whore and your gonna suck this cock after I cum in your ass.”  I told my sister the same thing and she actually started to cry.  I wanted to tell her that I didn’t want any of this and that this wasn’t my fault.  But instead I watched the video as the guy in it because to go in and out of the girls ass with his cock.  I began to fuck my sister’s ass hard, like the video.  I never fucked a girl in the ass before and never imagined my little sister would be my first time.  After about 5 minutes my sister began to fart with even stroke in her ass.  I could hear the guys in the room laughing and my sister began to sob.  She was so humiliated but I just kept on pumping my cock in and out.  Eventually I came with an explosion in her.  I came so hard that I know she much have felt it inside her body.  As I pulled out I watched the video catch up and as promised the guy told the girl to suck his cock and clean it.  I told my totally degraded sister to do the same and got to her knees on the bed and began to clean her ass juices off my cock as I laid back.  Although I never wanted to have this happen I had to admit that this blowjob was degrading to my sister that for some reason it really turned me on.  The girl in the video started to blow the guy and then she would move up on the bed and then fuck herself with the cock.  After she got her own juices all over it she would go down on it again.  My sister began to do this.  She fucked my cock for about 5 minutes and then she went down on me again.  She did this about 6 or 7 time before eventually like the video she just kept fucking me until I managed to come one more time inside her.  For some reason even though I came about 20 minutes earlier in her ass, when I came inside her tight vagina I felt like it was the biggest explosion in my life.  After I came inside her she kept fucking me until I was soft.  Like the video she then cleaned me up one last time.  My cock was so tired out that when she blew me this last time I could barely manage a semi-erection.  Eventually the video ended with the guy taking a tape out of the camera and walking out of the room.  As I did this I was approached by the three men who told me that their leader wanted a video of Americans forced to have incest for his collection and was paying them a very large sum for this.  They actually thanked me and told me to enjoy the rest of my life with my sister.  At this moment I realized that I could never even look my family in the eyes let alone my sister.  I knew my life was never going to be the same.
