My Sister Inlaw brought her date home from a costume party and I got to play the voyeur [MF][M] Long

My wife and her sister loved to talked about sex because my wife had only ever been with me so she was fascinated by what other men were like in bed. It didn’t bother me though, because in all honesty I’ve always fantasized about seeing my wife with another man, not sure how that would play out in real life but I’ve pictured it many times. Somehow roleplay came up in conversation one day. Now I dont know about you but I’ve always wanted to fuck my wife while she wears a sexy cop outfit and handcuffs me to the bed, or something along those lines. It’s yet to happen though. I’m not one to complain because she’s used the french maid costume she has a few times and that works for me as well, who wouldn’t it work for though really.

This only came up in casual conversation about fantasy and no one had brought it up since. Until my sister inlaw made plans for a costume party. My wife and I are not part of her circle of friends, and costume parties aren’t our thing, so we weren’t tagging along and she was going with one of her repeat Tinder dates so I was expecting to hear a show later.

They came upstairs dressed for the party and my jaw dropped. He was wearing a plaid shirt and jeans with a plastic axe in his hands. But she was wearing this sexy little police officer dress, that was half unbuttoned exposing this bright blue lingerie top that cupped her breasts and went up into a choker. [This](http://imgur.com/a/Fc34QYE) is the best I could find from googling. I couldn’t look away. I could see she was wearing stockings with a blue garter attached to it, so I could only imagine the bottoms matched the top. And boy was I imagining it. My wife walked out of the bedroom, saw her sister and said “Holy shit, good for you! Have fun tonight!” I threw in a voice cracking “Yeah have fun!” and they were out the door.

The wife and I had a quiet night as she had a bit of a cold, we watched a movie and I don’t think I paid attention to one minute of it because I couldn’t get that outift off of my mind. My wife decided to turn in for the night and I flicked over to some generic sports highlight show and spent an unknown amount of time scrolling through Gonemild and this subreddit, obviously horny.

Eventually my sister inlaw and her date stumbled in the door, half fondling each other and kissing. The guy saw me and said “Oh shit sorry dude” and quickly went downstairs. My sister inlaw, stood at the doorway in that amazing outfit and while starting right at me, unbuttoned the top half of her dress and opened it up for me to see her lingerie. She winked and said “We’ll try and keep it down, but no promises”

I shrugged and said “You do you”. And watched her walk down stairs. It was only 10 or so minutes until I heard her moans drifting up the stairs. Being the voyeur I’ve become, I silently crept down the stairs to get a better seat. There’s a small sitting area around the corner from her room so I took a seat and listened closely. The bed was squeaking rhythmically and I could hear a loud spank every so often, followed by a squeal like it hurt but she was loving it.

I rubbed my cock over my shorts and could feel precum soaking my inner thigh and my underwear. The squeaking stopped and I heard them shift around, assumingly changing positions. Very quickly I heard her deeply moan out “holy fuck your cock is so big, you’re so deep right now”. He started to fuck her furiously and I could hear skin slapping against skin and her moaning with each slap. This went on for a few minutes or so while I stroked my cock over my pants harder. The slapping stopped and I heard them shift around again, I could hear her starting to gag on what I assumed was her choking on his cock. He let out a “oh fuck im cumming” and I whispered a “yeah me too” as I filled my underwear with jizz. I didn’t stick around long and quietly made my way upstairs and in to my bathroom where I undressed and threw the cum stained underwear into the hamper. I stared at myself in the mirror and just smirked like I had gotten away with murder. I got cleaned up and got in bed with my wife. She had white noise playing, peppermint essential oils in the air, and was snoring away. Bless her sick little heart.

I was scrolling my phone, not overly tired, when I heard the date leave out the front door without locking it, how rude. I got out of bed, went and locked the door, and when I came back into the room my phone was lit up with a message from my sister inlaw. I grabbed it and headed in to the bathroom. She wrote “Is this what your fantasy looked like?” It was a picture of her in the bathroom with the dress fully undone, exposing the sexy matching top and bottom, and her dates cum still on her tits. I responded “Yeah pretty much, sounded like you had a good time down there”

“We definitely did, and lucky for you he loves being recorded. Enjoy the show” which was followed up by an imgur link.

My wife was sound asleep so I sat on the toilet and played the video. It started with them making out, him already naked, and her pushing him down on to the bed. Her dress was still half done up and she crawled on top of him and straddled him with his cock stuck up behind her. He grabbed her dress and slid it up, exposing her sexy blue lingerie and garter. She lifted herself up and placed his cock at her pussy and eased herself down. She wasn’t wrong, he had a big dick. I heard the bed squeaking from the video and watched her bounce up and down on his cock as he grabbed at her hips and spanked her. I could even see a red mark developing on her ass. He then sat up and picked her up, cock still inside and flipped her over on to her back. He pulled out and hopped off the bed, grabbed her legs and pulled her to the edge. She put her legs up on his shoulder and that’s when he slammed his cock to the hilt inside of her and she moaned out that sexy litte sentence. He pounded away for a few minutes and then pulled out and pulled her off of the bed, forcing her down to her knees. He started to jack himself off but she took over and did her best to deep throat his cock. She bobbed her head back and forth quickly until he was ready to cum which she then pulled back and jerked him off on to her tits. She stood up and kissed him deeply and then walked over to the camera and ended the video.

After I finished the video I realized my cock was throbbing and I hadn’t even touched it. I was too mesmerized by the video. I decided to take a little video of my own, so I started to jack off furiously with one goal in mind. When I was close to cumming I opened my camera and recorded my cock shooting a load on to my bathroom counter. I sent it off to my sister inlaw and said “Thanks for the material” to which she replied “Not a problem, you enjoy that whenever you want to. I know I will”

For the second time I cleaned myself up and went back to bed with my snoring wife.
