My wife's sister visits us every 2 or 3 months and stays for a few days. We walk in on each other all the time and have seen each other naked many times. She was planning on arriving at our house today at 5pm, so a 1pm, I was just chilling in the living room. I was laid back in my recliner, fully relaxed when I started playing with my dick and pulled it out. I was dreaming of sexy women and listening to music while slowly stroking my hard dick. My sister in law walked in the room and caught me. I was startled and embarrassed at first, but she kept standing there looking at me so I decided not put my dick away. We exchanged a few words and I jokingly asked her to lend me a hand and she did. My wife was at work and we both knew that she wouldnt be home until 5. She started off just jerking, then massaged and licked my balls, then sucked my cock. I came in her mouth and she swallowed my load. A little while later, she gave me a strip show, a lap dance and then we fucked. Twice. It was a little weird when my wife got home but we're back to normal now. I hope to fuck her again soon, she is like a chubby versiin of my wife.

Anyone have simialr a experience?

 

I would love to have sex with my wife's sister.

 

Unfortunately, my wife has a big, hairy brother. Your story is hot. Hope it's real. If so, post some pics. I think I can speak for everyone when I say we'd like to see her.

 

Happened to me at band camp.

 

Love to hear more.

You've seen each other naked in the past.
You knew she was scheduled to arrive yet you chose to sit back in your recliner and jerk off in the living room and somehow you were startled and embarrassed.

 

I have 5 SIL's and my wife was a serious exhibitionist back when we first met, and o course some of her sisters were as well and I've seen 3 of their pussies and all of their titties back when they were younger. One saw me and her sis fucking in the back of a truck one time, and after that she because a huge cock tease to me, always showing off her pussy to me and giving me a big smile as I looked at it, then up at her. I never wore undies and at a bday party one time, I was sitting in a beanbag chair so low to the floor and she was across from me with a pair of wrap around thin shorts and she was giving me an awesome show, then I went into the kitchen to get a drink and she follows me in and gets real close, pushing e back against the wall and gave me a big hug, then I noticed she started rubbing her little braless titties across my hest then push her hips against my crotch and I figured out she was trying to get me hard, quite successfully, then wet back and sat down across from me, whispered something to her girl friend that was with her and they giggled and both were staring at my crotch so I open my legs and let me see my hardon through the leg of my pants. Then she came over to sit right next to me in an overstuffed recliner, threw her leg over the chair and fully exposed her pussy to me for a while as we chatted. She cock teased me regularly but that was the best time, then a few years later I went to their house after work to pick something up and she was the only one there. I rang the doorbell and no one answered so I went it and yelled her name and she yelled back that she was upstairs so I went up and knocked on her door and she said to come in and she was laying in bed, covers over her, and she flipped down the covers to show she was in only a long t-shirt and her pussy was exposed and I couldn't resist any more and sat down on the bed next to her, touched her pussy and was feeling how wet she was, and we heard the school bus pulling up out front with the youngest one of the sisters getting home and that ended that. Nothing more ever happened with her, other than the teasing, but her whole experience was definitely memorable. And always wished I had gotten to fuck her, as well as another one that I actually worked with that had her own means of teasing and flirting with me.

 

I have no interest in my wife's sister at all but 2 of my 3 brothers are married to incredibly gorgeous women who turn heads wherever they go.
Unfortunately, they're not the type to mess around with a brother in law.
Oh well.
