This time I [32M] did see my sister [26F] having sex with my boss [61M] [MF]

Quick recap, I saw her giving him a blow job and then saw some pics on her phone, that part is [here](https://www.reddit.com/r/gonewildstories/comments/5jta53/i_32m_cant_stop_thinking_about_my_26f_sister/).

This time though I actually saw them have sex. It was last night, at around 10 that I was at my inlaws place for new years. We are a huge family so we get together sometimes there, sometimes with other relatives, etc. But there we were and my sister was wearing this very cute and revealing thing, very short skirt with very high boots and a red tight shirt, she looked very good to be honest. So we’re there all of us, like maybe 25 people between relatives and in-laws, and around 10:30 or a quarter to 11 she gets a phone call and immediately I knew it was from my boss. I don’t know why but I knew, maybe it was the look on her face or how she was smiling when talking to him but I knew. So she let’s everyone know that she’s gonna leave, and says goodbye to everybody, and everybody’s telling her to stay and whatever but she says she’s going to her friend’s house, which of course I knew it was bullshit, I knew she was going to see him and have a really good new years getting fucked.

So she leaves and I start plotting my escape because I need to go after her and see her. At this point she has become my obsession as you can see, not sexually, it’s weird, I just get off on knowing that she gets fucked and want to watch her.

So I wait until after 12 to celebrate new year’s with everybody and then make my way out. At that point most people are a little bit drunk so it’s easier to take off. I leave, get on my car, struggle to get out of the spot I was in and all the while curse at my cousin that parks her car like an asshole, but finally take off. I know her best friend and know where she lives so I head there, get there around maybe 12:30 but my sister’s car is nowhere to be seen. Fuck, where did she go? Is she getting fucked in some motel? That would be so hot but then I’m fucked and won’t be able to see her. So I get a bright idea and head home to use the find my phone on icloud to see where she is. I drive home, open the door, go upstairs and log into her account from my computer. I see her phone is somewhere on the freeway, so she’s driving somewhere, and I say fuck it this is pointless.

About half and hour later I check back in just to see where she is and she’s not about 10 minutes away from her place, so she wasn’t going anywhere she was coming back! I feel a rush of blood and head over to her place. I get there BEFORE her, so fuck I need to park a couple blocks away. I do and walk to her place, take out her spare key which I have and go in through the back. At that moment she pulls over and I peek over the gate to see her getting out of the car and the driverside door opens and who is it but my boss. FUUUUUUCK THIS IS GONNA BE GOOD!

He gets out of the car and I can see he’s a bit drunk, shouldn’t be driving but still he was. He was wearing a dark suit and opened the back door and got a small travel bag, so maybe she went to pick him up at the airport? Don’t know. The passenger side door opens up and it’s her, she’s wearing her coat but still wearing the same high boots or fuck me boots more like it, and the red tight top underneath. They laugh and go for the front door and at this moment I decide I will wait for them to get into the house and then I will get into the kitchen door and watch them fuck live. I make up my mind in less than a second. They get in. I wait a couple minutes and then head back to the backyard to peek through the kitchen door and whee if they are downstairs or upstairs.

I see them in the kitchen drinking and laughing, they are laughing about something that happened with another couple that I don’t know. Are they not just fucking on the side but actually dating? The guy is married. Fuck it. She takes off her coat and he immediately goes in for a kiss. He kisses her and grabs her waits and kinda lift her up. My sister is short in comparison, the guy is probably 6 feet or maybe 6’1″ so he has a good 10 inches on her. She’s wearing boots though so maybe he now only has like 5 inches on her. They start kissing and he kinda grabs his dick and she puts her hand there. FUCK I’m so hard right now but then they stop. They talk a bit more and then they go to the living room. I can barely see her living room from where I am and also I’m freezing outside but want to watch. Nothing happens for like 5 or 10 minutes and this seems like forever so I decide to go back to my car and maybe head out and call it a night.

I start to leave and once I’m almost at the street I see the lights to her bedroom turn on, so fuck it I’m going back. I get back again to where I was, see that they are not downstairs and open the door very carefully to not make any noise. I get in, close the door and just stay in the kitchen for a little bit to get warm and to kinda wait for them to feel comfortable in her bedroom. I then have this chill feeling going up my spine! What if my keys make a sound? What if my phone rings? Is it in silence mode? Is it set to vibrate? Are my shoes loud when I walk? Fuck! I decide to strip down to my boxers and leave shoes, phone, pants, shirt, jacket and wallet outside her kitchen door. I’m only wearing my boxers, my undershirt and my socks, at this point I’m definitely all in.

I’m freezing also but I start going up the steps. I’m making absolutely no noise. I her their voices though so they’re definitely not fucking yet, or so I thought. I hear my sister say something like, not without lube, or something like that and my cock that has been freezing for the past few minutes fills with blood and I have to keep going. I kinda lay down on the floor, on the steps, so that only my head is visible. They have the lights in her room on and the rest of the house is dark so they won’t see me. I see them clearly, I see the entirety of the bed. Finally I’m gonna watch my sister getting fucked like the little slut that she is.

They start off kissing. My boss is now wearing only his boxers and his shirt. His erection is quite visible through his boxers and my sister is still wearing the same skirt and top but she has taken her boots off. I would have liked to have seen that and I have a thing for girls taking off their shoes, boots or heels. He’s sitting on the bed kinda in between sitting and laying down and my sister is completely on her back, he’s on top of her kissing her, touching her legs up and down and she’s just grabbing his arms and chest. The kissing is very passionate and she’s making these little moan sounds that get me super hard. I need to stop touching myself because otherwise I’m gonna cum and ruin this whole thing. I also start thinking about maybe going back down and getting my phone so I can record this, but I decide not to, I feel that if I go back down I’m gonna chicken out and not come back upstairs.

They kiss some more and then my boss, whose name is Alonso, kinda takes his shirt off in a weird way from the top and grabs her by the waist, puts her on top of him and kinda tells her he’s missed her these past few days while also kissing her. She’s now on top and takes her shirt off, her bra is skin colored with lace and looks more like a gym top than a bra, her tits look huge though, bigger than the last time I saw her. He is just enjoying the moment as is she and now he kinda gets up so imagine like a cowgirl position bit with clothes on, she gets up from the bad and starts taking her skit off, she’s wearing matching color panties that are very short, most of her ass is exposed but is not a thong though. She slides the skirt off and bends over a little bit and Alonso takes his boxers off and his dick is just there, ready for my sister’s little hands to grab it.

Fuck this is really good! I need to go get my phone. I need to record this. As her back is to me and she kneels on the edge of the bed and starts to suck him off, he lays back and is just having a really good time. I decide it is now or never to go get my phone. I slowly walk back and head for the kitchen, open up the door and grab my phone. Slowly come back to the steps and crawl my away up to the edge of the steps, where I was. I look up and she’s kissing him, he’s putting on a condom and she’s about to ride him. She gets on top of him, at this point her bra and panties are gone so she’s putting his dick insider her with her hand, his dick looks huge regardless but her hands are so small it makes it look enormous. She gets it in and starts to slowly go down, he’s moaning and she’s moaning.

I turn back and open the camera, set it to video, make sure quickly that set it to airplane mode and start recording. Wonderful. She’s slowly riding him, he’s calling her his little slut, telling her how bad he wants her and she’s saying that she’s been dreaming of this fuck for over a month. Could this be the first time they fuck? Am I that lucky that I’m getting them on their first time? Fuck this is cool.

I keep recording but I can see that the screen is way to bright. The only light is coming from the bedroom but still if they were to look my way they could see a glare of light and wonder what that is. I quickly put the phone against my undershirt and head back down. I remove the case and try to put it in backwards and see if I can set the phone to record and keep the case on so that no light is coming from the phone. I kinda manage to feel that is working ok after a little test and start hearing loud moans and Alonso calling my sister the best fuck he’s had. Shit I need to run back up, fuck this recording thing.

I get there and she’s now on all fours, he’s giving it to her doggie style. They are both facing me. I can’t start the recording. I should have done so downstairs. I could go back, do it and then come right up, but I don’t want to miss this. He’s fucking her very hard, calling her a slut, telling her how tight her pussy is. She’s biting her lip again, that looks so fucking hot. Her hair is all over her face and she keeps moving it away. He stretched forwards and grabs her hair and pulls it, he’s now riding her. Her tits are just smashing against each other, I can see her ass taking a pounding, I start to jerk off. He stops to maybe puts his condom back on I think but no, he’s not wearing a condom anymore. She says she wants more, that he’s a cock craving slut. Wow. That like alone and how she said it, almost innocently, just wow. I turn back and want to record this, I take the phone and hit the red button and put the case back on and I’m back in business. At this point they’ve been going at it for like a good 15 minutes, feels like 30 seconds though. I know I have one good video of them but want another one.

She says she wants him on top and they go missionary, my sister’s legs on his shoulders and he’s powerfucking her. This lasts maybe another 2-3 minutes and she cums very hard, shakes all over and he tells her that now that she’s cummed he’s gonna fuck her in her tight little asshole!!! DAMN. He flips her over, she says go for it daddy, he puts on a condom again, his dick still hard, and starts to spit on her asshole, finger her and she’s maybe cumming again. He kinda puts ins dick in there and starts to slowly fuck her, she is crying a bit, moaning but says to keep going, and he does. He is pumping my sister’s little asshole and he is loving it. Her face is all covered in smudged make up, she’s face down and her ass still looks huge from my angle. He grabs her by the shoulders, kinda leaning on her, and starts to fuck her very hard and she is loving it! My sister is a slut, no other way around it. He then says how finding her on tinder was the best thing ever, she responds with fuck me harder daddy, he does. She then keeps saying fuck me daddy, fuck me, harder daddy, harder. He’s giving it to her, as hard as he can and she’s in pain I can see it in her face but at the same time she loves getting fucked like his. This can’t be her first time.

He says he’s about to cum and pulls out, flips her over again like she’s a doll and tells her to suck him off. I’m about to cum but don’t want to make a mess so I decide to do it with my boxers on, fuck if I make a mess as long as it’s not on her floor. He wants her to finish him off. She does and he cums. Her face is all covered in cum and her hair is a mess.

I know they’re about to get up or look around so I just head downstairs, open the kitchen door, get out, put my pants and shirt back on, jacket, grab my wallet, and go. I get in the car and drive away. It is not almost 3 am. I get my phone out at the light and take the case off and stop recording. I’m a mess my boxers are soaked in my which is ruining my pants too, my car smells like cum, but fuck it I keep driving all the way home. I get home and I’m so tired I don’t even want to take a look at the video, I just save it, both videos are like 43 minutes long. Decide to go to bed.

I’ve yet to watch the videos.
