"Let me in damn it" she hollered as she beat on my bedroom door.

"Go away" I yelled back.

"Open this door you little fucking pervert or I’ll tell mom what a sicko you are."

"You won’t tell her shit because if you do I’ll tell her what you were doing and then let her decide who the real sicko is."

"Come on Bobby, open the door, we need to talk."

++++++++++++++++++++++++++++++++++++++++++

Liz was my older sister. We shared the same birthday, but were four years apart in age. How mom managed it I’ll never know, but Liz was born on October 29^th at 6:14 AM and I was born on October 29^th at 6:29 AM.

My sister Elizabeth was, for the sake of truth and honesty here, a tramp. If she wasn’t my sister I’d call her a round-heeled slut or a whore, but she is family and tramp doesn’t sound as bad as slut or whore. Our current situation came about as a result of my sister’s round heeledness and my current (or most probably ex) girlfriends lack of the same trait.

I’d been working on getting into Gloria’s pants for almost six months and on each date she would get to within a cunt hair of giving in and then shut me down. I began to see her as a lost cause and I began to pull back. I dated her less and less and began looking for another girl who might be receptive to playing ‘bury the bone.’

There was a party that Gloria desperately wanted to go to that night, but she couldn’t go alone and I hadn’t asked her to go with me. Since all the other guys knew she was my girl they stayed away from her so none of them had asked her to the party. She decided that the best way to handle it was to call me and ask me what time I was going to pick her up. I don’t know whether she thought I’d think I’d asked her and then forgot or if she was assuming that since she was ‘my girl’ it was a foregone conclusion that we would go together.

I told her flat out that I was looking for some other girl to take to the party, someone more in tune with how I thought a date should go. Gloria then led me to believe that this would be the night she would give in. Being weak minded and with visions of pussy dancing in my head I told her I would see her at seven. To make a long story short I picked her up at seven, went to the party and then got in an argument with her, told her to piss off and then I went home.

At the house Liz, secure in the knowledge that mom and dad had gone out of town for the weekend to attend a wedding, and assuming that they had taken me with them, went about using the house as if she were alone. I got home at nine-thirty and as I walked in the front door I heard:

"Oh yes, oh God yes" from the upstairs.

I knew what was going on, but it didn’t concern me so I ignored it and headed for my room. When I reached the top of the steps I was surprised to find that the noise was coming from mom and dad’s bedroom. I had to pass their room to get to mine and since the door was open I looked in. On my parent’s bed, naked and flat on her back was my sister Liz. There was a guy between her legs pounding her pussy and two more standing next to the bed stroking themselves while they watched and waited their turn.

I knew Liz was a tramp [, but I hadn’t known how big a tramp. The reason I knew she was a tramp was because everyone else knew it and they talked about it and I overheard the talk.

When Liz was eighteen she was engaged to be married and the night of her fiancée’s bachelor party Liz went out with some girlfriends. It was her bad luck that her fiancée and his buddies left the apartment where the bachelor party was being held and went to the bar where Liz and her girlfriends were partying. Gary got there just in time to see Liz leave the bar with some guy and get in a car with him. They got in the backseat and when Gary walked over Liz already had the guys cock out and was taking it in her mouth.

Gary knew the guy and he knew that the guy knew Liz was his intended, but the guy was going to fuck her anyway and that pissed Gary off. He opened the door, grabbed a handful of Liz’s hair and jerked her out of the car and then he pulled the guy out and stomped the shit out of him. The entire time Liz was wailing:

"It’s not what you think; I can explain baby, I can explain."

She couldn’t of course, not that Gary ever heard her explanation. He spit on her, walked away and never spoke to her again.

Two years later she got married and four months into the marriage her husband lost a finger at work, went to the emergency room at the hospital and as a result of the injury he came home three hours early. He let himself into the apartment and caught Liz fucking the landlord. Turned out that she was pocketing the rent money for spending money and fucking the landlord to keep a roof over their heads. After Joe moved out she couldn’t find a job that paid enough to support herself so she begged mom and dad to let her move back in. They told her that she could, but she was told that she could never bring a man into the house and now here she was with three of them and on mom and dad’s bed at that.

None of the four noticed me and I stood there and watched for maybe thirty or forty seconds and just as I was going to head for my room one of the guys standing next to the bed said:

"Fuck this shit. She’s got two more holes. I’ll take her ass and you can have her mouth and then we can switch" and he climbed on the bed.

"Fuck" I thought, "I’ve got to see this" and I moved out of the doorway so they wouldn’t see me as they moved around. I stood off to the side behind the wall and listened.

"Roll her over Deke and get her on top of you."

Sounds of movement and then Liz asked, "What are you doing?"

"We gonna make you airtight sugar dumpling."

"Oh no, I don…glmph oomph."

Laughter and then, "Well, that’s sure one way to shut her up. Be careful she don’t bite your dick off when I drive it up her dirt road."

"Moogph oooog blpth."

"Stop squirming sweetie."

"Oooooooooooeeeeeaaahhh."

"God she’s tight. Must not do much ass fucking. Relax honey bunch, just relax. You gonna like this, I promise."

I waited another minute and then I looked around the doorframe. All three were plugged in and were battering Liz between them. The guy in her ass said:

"I think she’s getting the hang of it" and he stopped pushing. Sure as shit, when he stopped Lizzy started pushing her ass back at him. The man laughed and parodied that old cereal commercial, "She likes it, Lizzy likes it" and he laughed and started banging her again.

A minute or so later the man in Liz’s mouth said, "Here it comes sweet cheeks" and he grabbed the back of her head and held it while he pushed his cock down her throat. When he pulled out of her mouth he looked up and saw me.

"Hey sweet cheeks, looks like you have a fan club."

Liz looked over her shoulder and saw me standing there, and not just standing there - somewhere along the way, and without even being aware that I’d done it - I had freed my dick from the confines of my jeans and I was standing there stroking it.

Liz cried out, "Oh God, not him. He’s not supposed to be here."

That broke the spell and I turned and beat feet for my room. As I fled down the hall I heard Liz crying:

"He’s gonna tell. Oh God I’m gonna get thrown out. Oh fuck, why me? Why does this shit always happen to me? You guys have to go. I have to stop him. You need to leave now."

While she was saying that the men were talking. One was saying, "Bullshit sugar dumpling, I ain’t cum yet." Another one said, "Forget it sweetie, you’re already busted. No sense in stopping now" and the third guy was saying, "I ain’t leaving until I cum in your butt." Then one of them said, "When were done here we’ll go talk to the boy. We’ll make him see reason, right boys?" The other two chimed in with, "You bet Deke" and "Damned right bud."

I got to my room, locked the door and then propped a chair under the doorknob. That done, I debated going out the window and getting away from the house, but then I realized that the drop from the second floor window would probably fuck me up worse than those three guys would. I took several deep breaths and got myself under control. They couldn’t do anything to me! If they kicked down the door I’d have to tell mom and dad what happened to it and why. Same if they beat me up. But I still left the door locked and the chair jammed under the knob.

It was maybe an hour later when I heard them come out of my parent’s bedroom telling Liz they would call her in a day or so. I heard the front door open and then close and I went to my bedroom window and watched as the three of them got in a car and drove away. It wasn’t but about sixty seconds after that when Elisabeth tried the door handle, found it locked and started banging on the door.

"Come on Bobby, open the door. We need to talk."

"No Liz, I don’t need to talk to you. Just go away and leave me alone."

"Open this fucking door you little creep!"

Well that was certainly the way to go about getting me to respond so I shut up and let her beat on the door until she got tired and went to her room.

++++++++++++++++++++++++++++++++++++++

The main reason I wouldn’t open the door when she started pounding on it was I still had my boner from watching her with her three studs. Well, actually I didn’t ‘still’ have it. It had gone down during the hour or so between my going to my room and the three guys leaving, but it came back as I watched them walk to their car. Just seeing them brought back the memory of what I’d seen them doing with Liz and my woodie came right back. I laid down on the bed and ‘spanked my monkey’ while thinking weird thoughts about Liz and bad, bad thoughts about Gloria who was supposed to have taken care of me that night.

In the morning I woke up tied to my bed. I had gotten stupid during the night. I got up to go to the bathroom and I hadn’t locked the door behind me when I came back to bed. Liz had either heard me get up to go take my leak or she got up early. Whichever it was she tried my door and found it open. Whatever, I woke up with my wrists tied to the headboard of the bed and near as I could tell she had tied my right ankle and then passed the rope under the bed and then brought it up and tied my left one.

I looked over and saw Liz setting up dad’s video camera on a tripod and pointing it at me on the bed. I pulled on the ropes, but I couldn’t get free.

"Damn it Liz, what the fuck are you doing?"

"Oh, you’re awake. Good. Things will go quicker now."

"What are you doing?"

"I’m taking out some insurance."

"What the fuck are you talking about?"

"I’m talking about making sure that you don’t tell mom and dad about last night."

I had no intention of telling anybody anything about what I’d seen. It wasn’t any of my business and besides, I wouldn’t have wanted her ratting me out if I snuck a girl on the house with mom and dad gone and I told Liz that.

"Sorry, but I don’t trust you so we will do this my way."

She stripped down naked and seeing her nude body along with remembering the previous night brought my cock erect and Liz giggled and said:

"This is going to be easier than I thought."

She covered my feet with the sheet and then put a pillow where it would cover one of my tied wrists. She got on the bed and positioned her body so it covered the other wrist.

"Relax, this won’t hurt at all," she said as she lowered her head and swallowed my cock. She sucked on my cock for about two minutes while I moaned and thrashed around. Then she took her mouth off my cock, got up and repositioned the camera. Satisfied with the angle she cam back to the bed, gave me another thirty seconds of head and then she said:

"This is the good part."

She moved up, straddled my head and pushed her pussy down at my face. "Eat me Bobby, suck my pussy, make me cum you little incestuous fucker. Make your sister cum."

She took hold of my head in her hands and pulled it up against her snatch. "Eat your sister’s pussy Bobby, make me cum."

I’d never eaten pussy before and I damned sure didn’t intend to start with Liz, but I guess she must have figured that. She scooted up a little, pulled my face up into her cunt and cut off my air supply.

"Lick it Bobby, push your tongue in me. Lick my clit or suck it, but I’m not moving until you do."

I had no choice. I couldn’t breathe so I pushed my tongue in her cunt and moved it around a couple of times.

"That’s it brother, that’s the way to do it" and she let go of my head so I could get some air. "Eat my pussy Bobby and you won’t have to go through that again."

So I licked her cunt and I sucked on it and she moaned and told me how good it felt. After about three minutes of my licking her she got off the bed, moved the camera to a different spot and then got back on the bed with me. My cock was rock hard even though I wasn’t the least bit happy with what she was doing to me. Liz gave me another thirty seconds of mouth time and then she mounted me and started riding up and down on my cock.

"Come on Bobby, make me cum, get big sister off. Fuck me Bobby, fuck me."

I didn’t, mostly because I could barely move given the way she had me tied down, but it didn’t much matter because she was getting the job done all by herself. I had reached that point where the only thing that mattered was getting off. If mom and dad had walked into the room and started screaming at us it wouldn’t have mattered at that point - all that was my cumming. But even though getting off was all that mattered I was still pissed and I snarled:

"Take it you fucking whore and I hope it makes you pregnant."

I arched up into her as much as my restraints let me and just a half-second before I erupted Liz pulled off of me and I shot up into the air.

"There, now that wasn’t so bad was it?" Liz said as she got off the bed. As she took down the camera and tripod she said:

"Tell mom and dad about last night and I’ll give them this tape. It won’t matter to me because they all ready know I’m a slut. But you? They think that you are a good boy. When I finish editing this tape it will look like you just love fucking your big sister. Don’t go away now. I have to hide the tape before I let you loose. Oh, and one more thing. You are now a cock sucker by proxy. You just sucked Ray, Steve and Deke’s cum out of me. Hope you liked it."

She laughed as I threw up all over myself. When she came back she cleaned me up with a wash rag before she cut my feet and my right hand loose.

"You have to cut your left loose; it will give me time to get out of the house. I don’t want to be here if you decide to get violent."

She dropped the knife on the bed and as she was leaving the room I screamed at her, "I’ll get you for this you fucking bitch. I swear to God I’ll make you pay." As I cut myself loose I vowed I would make her pay for what she did to me. Not the blow job or the fuck, but she would pay and pay dearly for sitting on my face and forcing me to lick her lovers out of her.

++++++++++++++++++++++++++++++++++++++++++++++

I didn’t sweat the tape she made because I had no plans on telling mom and dad on her anyway. Besides, I knew where the tape was. She would have hidden it in her ‘secret place’ which was where she hid her diary and other private stuff.

When I was thirteen I saw her writing in her dairy and being a normal thirteen year old I was curious and so I went looking for it. Every time I was home and she wasn’t I went prowling in her room. It took me five days of snooping a couple of hours a day, but I finally found it. She had built a shelf inside the cold air return to the furnace.

Her diary was a gold mine and if I’d been prone to blackmail I could have taken it and threatened to give it to mom and dad if she didn’t give me whatever I wanted. Instead I just settled for reading it. It read like a porn novel. I discovered who got her cherry, how many back seats she had decorated and a whole host of other stuff. If she considered the air duct safe enough for that steamy little book I bet it was good enough for the tape. As soon as I was free I went to her room and checked and sure enough it was there. I left it alone, but I did get the brand name. I’d buy a blank tape and switch them later. The big thing with me right then was getting even with Liz for the rotten trick she had pulled on me.

+++++++++++++++++++++++++++++++++++++++++++

For the next two months I drew up elaborate and detailed plans, none of which I could figure out how to actually make them work. And then Liz went and set herself up for me.

My parents had gone to my grandparents and were going to spend the night. After they had gone Liz had gotten on the phone and invited some guys over to party. I was in the kitchen making myself a sandwich when I heard her tell them that she would meet them at the bar around seven and then they would come back to the house later. And then she said:

"No, I don’t have to worry about my brother" and she smirked at me. "We have an understanding, don’t we Bobby?"

I just glared at her, finished my sandwich and then went to my room. I was fuming over that smirk when I had my idea and the more I thought about it, the more I thought it would work. When Liz left to meet her boyfriends I went to mom and dad’s bedroom and looked for a place to hide the video camera. I assumed that she would use mom and dad’s bedroom since they had a king size bed and the bed in her room was only a single.

Dad’s video camera had a remote, but for the remote to work it had to be line of sight to the camera. I’d have to be outside the bedroom window on a ladder so I could aim the remote. I went over to the window and stood there and surveyed the room. I saw a place I could put the camera, have it focused on the bed and still have line of sight from the window.

Next I went out to the garage and got the aluminum twenty-foot extension ladder, took it and set it up. I put the camera in place and then did a couple of dry runs and everything worked fine. All I needed was for Liz to cooperate - she had to bring her lover (or lovers) to my parent’s bedroom instead of hers. One last detail to take care of. I couldn’t find a blank tape so I had to take the one out of Liz’s air duct and tape over it. I felt real bad about that (ha ha).

+++++++++++++++++++++++++++++++++++++++++++++

It was close to eleven when I heard Liz come home and from the noise she made she had more than one man with her. I was waiting in the basement instead of my room. I knew Liz would leave the bedroom door open just to rub my nose in it. That meant she could possibly see me if I left my room to go outside and I didn’t want her to think of me at all. I didn’t want her to wonder what I might be up to.

I gave her several minutes and then I went out behind the house and climbed the ladder. Liz had four men with her and they all ready had her naked. I just stood on the ladder and watched. The tape in the camera was only thirty minutes long and I wanted to get the good stuff.

The men all undressed and then sat down on the edge of the bed in a line. Liz walked over to the guy on the left end of the line and knelt in front of him and started sucking his cock. After a minute she moved to her right and took the next man in her mouth. I aimed the remote at the camera and pressed the button. I hoped that the camera was working, but since I had taped over the little red light I couldn’t be sure.

I got nine minutes of Liz working along that line of cocks and then I stopped the camera. I wanted to save tape for what I hoped Liz would do - I wanted to tape her doing three guys again. After twenty minutes of crawling on the floor and sucking cocks Liz got up on the bed. One man lay down on his back and Liz got on her hands and knees between his legs and started to suck his cock. A second man moved up behind her and slid his cock into her and I got two minutes of Liz being double-teamed and then turned off the camera.

The two men came and the other two took their places and I got another two minutes. When those two got their rocks off it became a boring imitation of a porn video as Liz laid on her back and took them on one after the other. I was getting tired of standing on the ladder and I was just about to turn the camera on and let it run while I went to bed when Liz got up to let one of the men lay down. She moved over him and settled down on his cock and then bounced up and down for a minute and then a second man moved behind her. It was what I was hoping for - Liz was going to take one in the ass while she had one in her cunt.

I turned the camera on and was not disappointed when, two minutes into the double fuck, another man moved up to offer his cock to Liz’s mouth and she took it. I had what I wanted and all I could do was pray that the camera worked. I got down off the ladder and went up to my room and went to bed. I had to pass the open bedroom door, but no one noticed me.

I woke up when someone climbed into bed with me and I heard Liz:

"Bobby? Are you awake Bobby?"

The clock on the nightstand said that it was three-thirty. "What do you want Liz?"

"I need a favor Bobby. Do it for me and I’ll give you the tape I shot of us."

Whatever she wanted I couldn’t give it to her because if she went to get me the tape she would see that it was gone. However I was curious so I asked:

"What do you want?"

"Would you eat my pussy Bobby?"

"Are you fucking nuts? In the first place you are my sister and even if you weren’t there ain’t no way I’m sucking your cunt after you’ve had four guys in you."

"Oh come on Bobby, it didn’t kill you the last time and I had one of my biggest orgasms ever."

"Yeah, and I threw up all over myself. Get the hell out of here Liz."

"I’ll suck your dick. You can fuck me too, all you want. Come on Bobby, please?"

She reached for my cock. Sister or not, do you have any idea how hard it is to take a female’s hand off your hard cock and push it away?

"Get away from me Liz" I said as I pushed her out of my bed.

"Fucking asshole!" she snarled at me, which pissed me off so I replied, "Fucked out whore" as she walked out of my bedroom.

The next morning after Liz left the house I put the ladder away and went and got the camera. It had worked perfectly. I went into dad’s den and used his double VCR set up to copy the thirty minute tape onto a VHS tape and then I returned the cassette to Lizzy’s ‘secret place.’ Then I sat back and watched the entire tape. After I had gotten off the ladder the tape showed Liz being a fuck pig. She took on all four men, three at a time, until the tape ran out and I would suppose for a couple of more hours after that.

I hated to admit it, but watching my sister be a slut gave me a stiff prick and I ended up beating myself off - several times. When I was done watching I labeled the tape Automotive Body Repair and put it in my room with all of my other tapes. All I needed was a time to use it, but over the next year even though there were a few times that would have served I passed on them. I wanted something really good, something that would have a major impact, something that would let Liz know just how pissed at her I was over what she had done to me.

Liz herself gave it to me.

++++++++++++++++++++++++++++++++++++++++++

Liz met a guy, fell in love (or lust - you couldn’t always tell with Liz) and cut out group fucking or at least did it without my knowing. They were a steady couple for about six months and then Don asked her to marry him. Liz didn’t hesitate, she said yes and they set a date.

I liked Don. He was a great guy and I felt sorry for him because I knew what Liz would do to him after they got married. And no, I didn’t have to give her the benefit of the doubt because she just might be true to Don. Two weeks before the wedding I answered the phone and it was for Liz. I recognized the voice, it was Deke, one of Liz’s fuck buddies. I called Liz to the phone and then I left the room, but even from the next room I could hear her side of the conversation.

"No lover, not tonight. Don is taking me to the movies."

"Yeah, tomorrow would be good. Don bowls so I won’t have to worry about him. I’ll have to be home by ten-thirty because he always calls."

"No baby, I don’t know how we will do it after the wedding. We will just have to play it by ear. Oh and by the way lover, make sure everyone has condoms. I don’t plan on having anybody’s babies except Don’s."

There it was. She wasn’t even married to him yet and she was already planning on doing him dirt. Knowing what I knew I didn’t feel comfortable around Don any more. How could I look him in the eye knowing he was already fitted for a cuckold’s horns? I even told Ralph, the guy setting up Don’s bachelor party that I wouldn’t be showing up. Word got back to Liz that I wasn’t going and she had a fit.

"What is it going to look like if my own brother won’t go to my fiancée’s bachelor party?"

Then my mom chimed in, "She’s right Bobby. Don is joining our family and so you should be there."

Next was my dad. "You really do need to go Bobby."

How could I tell them that joining our family was the last thing that Don ought to be doing? But with Liz constantly pushing the issue my parents kept after me until I finally agreed to go.

My not going was not the only thing that Liz had a fit over. She heard that Ralph had arranged for a stripper and she went ballistic until Ralph threw up his hands and said, "Okay, no stripper. Just beer drinking, card playing and porn video watching."

Liz wasn’t too keen on the porn videos either, but she decided not to push her luck.

+++++++++++++++++++++++++++++++++++++++++++++

It was my first bachelor party so I really didn’t know what to expect. Without a stripper coming it was just a card party with beer. We played poker and drank beer for about two hours and when everyone was in a mellow mood Ralph said:

"Come on guys, lets watch some porn."

Everybody gathered around the TV set and Ralph popped a tape into the VCR. It was "Debbie Does Dallas" and between shouts of, "Wow, look at that" and "She could spend the night in my room anytime" we critiqued Debbie’s performance. The second tape was "Total Reball" starring Ashlyn Gere and when that tape was over there wasn’t a soft cock in the house. Ralph ejected the tape and took the next one in the pile, put it in the VCR and pushed PLAY. The image filled the screen and there was dead silence as sixteen guys heard Liz say:

"Okay, here’s the deal. Last one to cum in my mouth gets to be the first one in my ass" and then she started her round-robin suck job on her line of four guys. I quietly got up and split.

+++++++++++++++++++++++++++++++++++++++++++

It was two days before Liz came looking for me.

"You little bastard, you did it, I know you did. No one else could have. Well I’m going to make you pay you fucking asshole. We will just see how mom and dad feel about you after they see my little surprise."

"I wouldn’t do that Liz. It will just end up biting you on the ass."

"Fuck you Bobby. You ruined things for me with Don and I’m going to make you wish that you never fucked with me."

"I didn’t ruin shit for you and Don. All I did was make sure that it happened sooner rather than later. I heard you on the phone with Deke telling him to make sure that everyone had condoms and how you didn’t know how you were going to fuck him after the wedding, that you would just have to play it by ear. All I did was save Don some grief."

"It still wasn’t any of your business. You fucked it up for me with Don and I’m going to fuck it up for you with mom and dad."

"You are wrong Liz. It was my business. I promised you that I would get even with you for that stunt you pulled on me when you made that tape and had me suck those assholes out of you. I’m telling you for your own good Liz, call it even and let it go. If you do it you will just make matters worse for you."

"Fuck you Bobby!"

++++++++++++++++++++++++++++++++++++++++++++++

That evening when I got home from classes mom called caught me on the stairs as I was going up to my room.

"Bobby? Could you come into the living room for a moment? Elizabeth has something she wants to show your dad and me and since it concerns you she wants you to see it too."

I followed her into the living room where I found dad sitting on the couch and Liz standing by the VCR. She sneered at me and said:

"I already know what you think of me; let’s see what you think of Bobby after this."

She pushed PLAY and the image leaped off the screen at mom and dad as they heard the audio:

"Okay, here’s the deal. Last one to cum in my mouth gets to be the first one in my ass."

"That’s our bedroom!" my mother exclaimed and Liz’s face turned pale as my father leaped off the couch, stormed over to the VCR and ejected the tape.

"Elizabeth Ann, I want you out of this house now! Get packed and get out!"

Liz ran crying from the room and dad turned to me and asked, "Why would she think that this would make a difference in how we think of you?"

"Who knows how Liz thinks. If you will excuse me I have a term paper that I need to get to work on" and I got up and went to my room.

++++++++++++++++++++++++++++++++++++++++++++

Liz moved out. She was so stunned by the sudden turn of events that she never did try to lie to my parents about what had happened in my room that night. Although Liz eventually reconciled with mom and dad our relationship never got any better. The only times I see her are at family functions like Thanksgiving, Christmas and Easter and then we rarely speak.

Liz has apparently finally found what she was looking for. She married three more times and two of them ended like I knew her marriage to Don would have ended - with hubby walking in and catching Liz with her lover (or lovers). The third one might last. She seems to have found a guy who likes to swing or who gets off on her having sex with other men.

There was one more disturbing outcome of the whole affair. Dad made a big production out of destroying the tape of Liz and her lovers, but once, when he thought he was home alone, I saw him watching the tape and stroking himself. I wonder what’s up with that?
