My Sister Jenny - 03

I hid some cameras in the house, so that I would learn more about the sex life between my Sister Jenny and my dad.

Looking for some secret surveillance cameras to spy after my dad and my sister after I saw them fucking eachother, I knew the perfect man for this job. So the next day in school I had an four eye talk with Benny. I told him that I needed surveillance cameras because I needed to find something out. But they needed to be small and without the recording red dot because I had to discover something. He grinned over his whole face. "You wanna watch your sister showering? You know sharing is caring." He was always a little more pervert in my friends group about sexual things, than all the other ones. Maybe a little bit to anal fixated. But I did not know if it was just shit talk under friends. Or if he knew how close he was with this guess. So I tried to play it on the shit talk way. "As soon as you share your nude recordings from your mom. No I need it for some other privat stuff. So please do not tell anybody." I saw a little flicker in his face as I said the thing of the recording of his mom. But was not sure if it was because he felt annoyed or catched. I would not mind it at all, if he was doing such things. His mom was still in good shape for an age of 36. Good looking. Dark shoulder long hair. Her tits were bigger than average. Like her ass. And both still seemed to be firm. But he overplayed my comment about his mom and was the buddy I needed in this moment. "Sure. Maybe you can come to my home after school. I could have the right thing for you." That sounded really great. I did not expect, that he would have anything already there. Maybe ordering something or getting stuff from some illegal sources. So after school as Jenny was driving me, Benny, Shawn and Lazy (his real name was Leslie but we called him Lazy because he was the real opposite of this). I was seeing that Benny was checking out Jenny. I did not know, if it was because he imagine her being recorded nude by me. Or if he always checked her out. At least I did not remember that I saw him doing it in the past. But after yesterday I was not sure, if I would even have noticed anything about such things.

Benny lived the closest from us so Jenny would drop out Shawn and Lazy first. I told her, that I would hang out with Benny and would come later home. It was okay for her. But she told me to write her, when I would make my way home. Or if I needed a ride or anything. I thought 'Yeah, so you and dad would be warned in time.' But I played along. Little did I know at that time, that it was real sisterly love. And that after mom had left she felt responsible for me. And looked after me so that I was doing well. Me and Benny were going in his hobby room. Where he would have all his computer stuff stored. He took out of a cupboard a box. In it were about 10 small cameras. But seeing the open spaces in it, there should be 20 cameras fit in. So probably he had already some of them in use. But I made no remark about this. He told me, that these cameras could be connected to a computer or a home base. Which would record everything more secretly, because it was smaller. The cameras could also save the records. But because they only had limited capacity it would only be possibly for several hours depending on the resolution and if they would also record the sound. They had also a motion detection feature. With this they would save storage space and could record more hours, depending how often the motion sensors would be triggered. He instructed me how to setup the cameras and how to handle all about it. Because I also was kinda computer geek, it was easy to follow his instructions. He asked me for how long I would need them. That was a point I did had not been thinking about till this moment. After a quick thinking I told him about a month. He gave me 6 of the cameras and a home base. And told me to be carefully with them, because they were expensive. One costed more than 100$. And if one of them would be destroyed, I had to pay him. I agreed. Gave him a friendly good bye and thank you hand shake. And texted Jenny that I was on the way home.

During the weekend I tried to figure out, where I could place the cameras. The living room was no problem. There were enough decorative items where I could place them. You would need to get really close and really looking for them to discover them. But my dads and my sisters rooms were a problem. I normally would not going in there rooms without a reason. And I needed time to check the rooms, for some perfekt spots. Luckily saturday afternoon Jenny went to some of her friends and dad was going to the shopping center to get new clothes and some stuff for the garden. So I had about 3 hours alone in the house. I found in every of the 3 rooms two good hiding places, facing the bed or the couch at different angles. I connected the home base with the cameras and set up the recording at best quality with sound and motion detection on. All I had to do was waiting, getting them some time alone and rewatch in fast forward once in a while if I could spot some fascinating situations. During the next week the cameras recorded several fuck sessions between them. Not every day. If they were doing it, I mostly was not in the house. And then my dad would fuck my sister two or three times. Mostly he would at least fuck her once and get his cook sucked off the second round. I also saw him once even fucking her up her ass. This did not look as satisfying for my sister as getting fucked up at her pussy or swalloing his whole dick. But I could see, how good she was handling it. And she was happy at the end, that she could satisfy my dad that way. They always told themselves how good it was. And how much they loved fucking each other.

I once watched, that after both were in bed, that Jenny probably had dirty thoughts, because I could see her rubbing her cunt under her blanket. After a while she got up and went to her fathers bedroom. I could see her there handling a device on dads nightstand which locked like an alarm clock. My dad was already asleep. Jenny stripped herself out of her nightgown. She pulled his blanket off of him, knealed on the bed and freed his dick out of his night shorts. She immediately took his limp cook into her mouth and startet sucking on it, while she urgently massaged her cunt with one hand. Dad woke puzzled up. But was immediately into it. She soon stopped sucking his dick, sat herself on his groin and guided his hard dick into her cunt. She started riding him hard, while he kneaded her breasts hard. Because she was turned on before, it did not take long till she rammed her cunt completely and hard on his dick and her whole body twiched in an orgasm. She then laid still on dad. Dad kept caressing and fondling her tits and her body. Jenny was not humping him anymore, but now he needed his release. He hold her firm and rolled her over on her back, with him now on top of him and without even his dick sliding out of her pussy. He immediately started pumping his dick in and out of her cunt. My sister just laid there spread legs, arms clutched around his back and happyly moaning and enjoyed him having his way with her. Finally I could see him cumming in her cunt. He rolled of from her and they cuddled together and slept naked in the bed of my father. The next mornig the thing on dads nightstand, that my sister had set up the night before, was starting an alarmsound. They both startled up and dad turned off the alarm. Jenny still butt naked picked up her nightgown and tried to rush silently back to her room naked. I saw on an other camera, that I was just entering the living room. I figured out, that this device must be the alarm for the connection door.

Another night it was dad who was in need. I saw him going out of his bed to my sisters room, already his hard dick stroking and the alarm device in his hand. He closed her door put the alarm on her nightstand. He pulled her blanket to the side and climbed in her bed between her legs. She woke up and realised what was about to happen. He did not take the time to undress. He just pulled his pyjama bottom over his hips. And he wasted also no time undressing Jenny. He just ripped her night pantys off from her painfully. He used a little spit to wet his tip and shoved his cook needingly into her dry pussy. Jenny let out a painful gasp. But she did not stop him or looked angry about this. She just let him have his way with her. Soon I could hear wet noises from him fucking her, showing that her cunt had reacted to the pounding. Even if my dad kissed her sometimes or fondled her breast, his main focus was on fucking his dick hard and cruel into her cunt. Jenny started moanig but it was clear, that this would not bring her near to an orgasm. Dad needed only 5 minutes until he started pumping his seed in his little girl. They kissed and stroked eachother afterwards, but then dad got up, pulled his night pants back over his hip and went back to his room. Jenny was wiping the cum, which leaked from her cunt, from her bed with a tissue and went back to sleep. She later told me, that they had bought some cheap nightwear and prepared them a little bit, so that he could easily ripp them off from her, if he was in his hard sex mood.

By seeing them having sex more and more often, I recognized how much I felt left out. How much I was jealous about it. And with every time I watched my sisters cunt got pounded or her sucking dads cock and seeing her naked and cum running down her leg, I wanted more and more to be the one, who could fuck her. I needed more and more to feel her cunt around my dick. Wanted to feel my cock being sucked of. And shooting my load in any of her orifices. But I did not know how. Even if this was wrong, what they were doing, I still loved them. And watching them enjoying the sex did not feel wrong at all. And I did not want to blackmail them with the recording. And then something dark happened which leaded to me finding out the real beginning of this all.
