Spied on [M]y girlfriend’s sister have sex and she knew. | 2016

Its Long but worth it, Thanks for reading. [Background]

I’ve been with my current gf for a little over 4 years now and I’ve always had a little crush on her older sister, who we’ll call Elly. We started going out a couple weeks before we graduated from high school which was about 4 years ago, one day after school my gf told me her older sister, who is a couple years older than me, was going to pick her up from school so I would get to meet her. We were waiting in front out the school when Elly drove up. She was wearing a tight t-shirt and short shorts with her dark brown hair up in a pony tail. She had an amazingly petite 5 foot 3 inch body and probably weighed about 115 lbs, perfectly fun sized. She had smooth pale skin and the hottest lips/mouth that I’ve ever seen, they were the kind of lips that would look great wrapped around a hard cock. She also had the most seductive brown eyes and when she smiled, she gave a facial expression that screamed “I would fuck you silly and drain every ounce of cum out of you”. I would say she mostly resembles the porn star Callie Cyprus which, fortunately for me, turns out they have VERY similar body parts.

Over the 4 years of knowing Elly I would always check out her amazing body whenever I got the chance A couple times she would catch me staring at her great ass but, she would just brush it off and keep doing whatever she was doing. Whenever she would visit or when my gf and I would visit her, I would always have a fantasy of us getting drunk and having a hot fuck session but, the most I ever did is jerk off in the shower while thinking about the fantasy. I also learned that she was a slut and loved to fuck, she would often introduce me to a new “boy friend” almost every other visit or so. She would joke around saying that she’ll just use a man for sex then move on to another like a black widow. My gf would tell me about the many times she caught Elly fucking some random guy when she was in high school. I don’t know why but, just knowing how much of a slut and tease she is, makes me want to fuck her even more.

A couple months ago my gf , Elly, and myself were trying to save some money since we all worked part-time jobs but never had a lot of spending cash so we decided to move into Elly’s apartment. A month before our arrangement Elly started going out with a guy names James and they hit it off good, so much so that he ended up moving into the apartment a couple weeks before we did. I had to admit, I was a little jealous having another man around a long term crush but, it was all good, I still got to check out Elly’s sweet body on a daily bases especially when she would work out in the apartment.

The first month living in the apartment went by pretty well and over time I notice Elly wore less clothes as she began to get use to me being around. It got to the point where I challenged myself to check out Elly’s body without getting caught. The rush of getting caught is what eventually led to me discovering my kink for voyeurism. One night after Elly finished working out she said she was going to take a shower so she went into her room and closed the door. As I was going to my room down the dark hall I notice a glimps of light coming from Elly’s door frame. It turns out that her door frame was crooked, allowing any passerby who was walking into the hall to see inside her room through a small opening between her door and door frame. If she had her bedroom light on then you could see even better. I got a rush of adrenaline just thinking about me being a peeping tom and seeing what Elly does behind closed doors.

The next day Elly finished working out and went to take a shower. I casually got up after her and acted as if I need to get something from my room. When I came up to her closed door I saw she left the light on and I had yet to hear the shower turn on. I made sure nobody was going to come down the hall way and moved my head closer to the small opening of the door. My heart started racing in anticipation of possibly seeing Elly in her underwear or even better, fully nude. Then It happened, I heard a little cough come from inside Elly’s room and there she was, standing perfectly aligned with the opening, facing away from me, looking at herself in her bedroom mirror and fully nude. My heart started racing and my cock started getting hard from looking at her perfectly smooth skin, her petite hour glass frame, and her perfectly toned ass. At that moment I would have given anything to bend her over and fuck her like no tomorrow. We both were admiring her body for a good 20 seconds then she continued to the shower. I went into my room and laid across my bed to evaluate what just happened. I was shaky from the high amount of adrenaline going through my body but, I still wanted see more. I had yet to see how Elly looked naked from the front and this would be on my mind for the next couple days.

One weekend morning Elly and James were in their bedroom, they left the door cracked open about 2 inches and when I walked by I saw them laying on the bed with a small blanket covering them, they were just talking to each other so I said “good morning” as I walked back and got a “good morning” in return. I was in the living room drinking coffee and on my laptop looking at Reddit, while my gf was still in bed fast asleep from working late that night before. As I sat at the table I could hear Elly and James continue to talk and make fun of each other, and then I noticed the apartment got really quiet for no strange reason. I figured Elly and James were probably doing a little foreplay with each other since It got quiet out of nowhere and they knew I was up and about. So being the curious young man that I am, I go to “investigate”. I quietly go into the hallway and slowly approach Elly’s door. I stop about 6 feet from the door, they still have it opened about 2 inches and I can fully see all of Elly’s bed. I then realized what was going on, I was correct about my initial thought of them messing with each other. There I stood in shock and awe, to Elly sucking James’ cock. They made no attempt to cover up even with the door open and they had no clue I was in the hallway. I continued to watch Elly slide her amazing lips around James’ hard cock as she took more and more into her mouth. She had one hand firmly cupped around his balls and the base of his shaft. I could not believe what I was fucking witnessing before my eyes. I kept wishing I was in the kind of porno where a third male enters the room and begins to lick the girl’s pussy while she continues to suck off the other dude but I knew that would never happen. Fortunately for me it got better.

I was still unnoticed in the hallway and Elly decided she had enough of cock sucking. She got up, slowly took off her clothes then got on top of James. There she was straddling James, she had her back arched making her ass stick out giving a perfectly round shape. She then went down to kiss James with her ass still sticking out, that’s when I saw her heavenly pussy and perfectly smooth asshole. Her pussy was shaved and very clean with the just right amount of bush. Needless to say, she definitely had similar lower body attributes as my gf and I felt like I was looking at my own gf. Elly then reach her hand under self, grabbed Jame’s cock then slowly slid it in. Watching her tiny pussy slowly stretch wider as she took more cock was going to send my over the edge. Her small frame truly showed how tight she was and she managed to get all of his cock in, probably to the point where he could easily be touching her cervix. Elly began to ride his cock like the slut she is, sliding her cunt from base to tip. I would see her perked up asshole every time she slid down, she would stick her ass out making sure to get every possible amount of dick inside her. I wanted to walk in and slide my cock into her ass so badly but all I could do is stand there and watch.

After a good amount of time riding cock they switched to another position. The both laid on there sides in a spooning postion and James slid his cock into Elly from behind. Elly was facing towards the wall by the door and when She felt that hard cock slide into her, she gave a slight but ever so seductive “O” face then slowly closed her eyes. I knew she loved getting fucked and I was extremely jealous that I could not be the one to fucking her. James started off slow, making sure to get deep into Elly then as he picked up the pace he would ram into her harder and harder. Elly’s face now expressed a look of pure lust as James was pounding away at her pussy. Elly then moved her top arm around James’ body and raised her top leg exposing her succulent pussy. I think that was her way of letting him know that she was enjoying getting fucked. Fortunately for me, when she moved her arm and leg, she gave me full uninhibited view of her small body, perky tits, flat stomach with a belly ring, and her shaven pussy with her little bush. Her nipples were tiny but slightly hard and they perfectly matched her body. At this point I realized she looked exactly like one of my favorite porn stars, Callie Cyprus, it made the whole situation even better.

Elly was still getting fucked on her side when she started to move her body around more and while she did this I could have sworn she looked towards the open door. It lasted only about a second but the fear put into me made it feel like minutes. She stopped moving her body then closed her eyes and slowly laid her head down. My heart was racing and I knew she had just seen me but she did nothing and continued to get fucked. I still stuck around and a couple minutes later James held onto Elly body closely as he began to pump her pussy with his cum. Elly was on birth control and I desperately wished to be James in this situation. As she was getting filled up with sperm all she did was lay there on her side, exhausted from the intense fuck session I had just witnessed. Sticking around from beginning to end, I decided I had seen enough and went back to the table. My coffee was now cold and my computer still on the page I had left it. When I got back to the table I heard someone use the restroom then Elly came out from her room. As she walked towards the kitchen, our eyes met and she gave me a smile and one of the sexiest, “how was your morning?”, I replied, “it was nice”, then she said, “Your welcome”.
