Sister-in-Law

Yesterday I managed to get a full downblouse look at my SIL's braless tits under a baggy t-shirt as she bent forward in her kitchen, my wife was only 6feet away but didn't see me ogling her older sister, instantly got a hard on and had to awkwardly hide it for the duration of out visit.

Does she have any idea that you are so into her? Maybe she is teasing you

I think she knows I like her sexually, she does see me as a big brother though and regularly gives me hugs and the odd kiss and sits on my lap.
 
I've had a browse and can't find a live thread, but I'd be really interested in fantasies or experiences of people with their sister-in-law. Was she hotter than your partner? Easier? Or just more fun?

I know I masturbated on my ex's sister's bed as she had such great tits...

I am the other way around, my BIL is really cute.
 
My sister in law is nymph. She was trying to seduce me from the moment I started dating her sister and she finally got me about two months after our wedding when she was visiting us interstate. We than had fling for several years until she got married herself. She separated last year and we got into it couple of times since...
In all other aspects, my wife is 100% better than her, but their sexual drives are so different... For my wife, once a week is enough. For me and her sister, once a day is not enough...
 
Last evening my wife and SIL came home drunk, sil had heels, short black dress showing off her little tits in a push up bra, after a glass of wine and much leaning forward and lots of views of her satin bra she got up to get her cab, asked me for a kiss and a squeeze goodbye, thing was, she had her mouth open, I couldn't resist and French kissed her and pulled her close, my cock was instantly hard and she must have felt it digging into her, I'm wondering if she remembered this morning.

My sister in law was exactly the same, from the moment I was introduced to her she was a complete flirt. My wife told me that her sister had a history of trying to seduce her boyfriends. I started thinking it was fun to flirt with the younger sister until she took it further, flashing me and then on my wedding day she tried to seduce me. I won't lie, I enjoyed every second but when we ended up having a full blown affair it was so intense I quickly realised she was crazy, the sex was amazing but she was like a stalker by the time we split and ended the affair, we had two pregnancy scares and she asked me to leave my wife for her.
 
Dated Two...

Girls in the past when I was in my 20s and always wanted to fuck their sister.
Maybe because they were a bit older than me and total MILFs - but it was just a fantasy.

But SIL always turn me on - it feels taboo but so hot!
 
How did you get hold of the pics?
I have a few clothed but revealing ones of my SIL from over the years in a secret folder on my phone which I perv over every day.
She left herself logged into her email
Session one day at my house checking on something
She was exchanging naughty pix and bids
With several guys...couldn't resist but grabbing some for use in play thinking of her. Knowing just how naughty she was only confirmed what I already thougt, only making her hotter
 
My sil told me a few years ago after a drunken evening that her and her late husband made a porn video together back in the early 90's, but I never managed to get my grubby hands on it unfortunately.
 
Wow - glad I found this thread.
My SIL and I have had a 'flirty' relationship for years. She's 2 years older, but a body of a 30 yo.
She divorced about 3 years ago, and the flirts have gotten hotter.
Even my wife noticed, and she jokes about it saying stuff like 'guess I'd better not leave you 2 alone for long' and stuff like that. Family get togethers are always fun.

Hmmmm. Maybe your wife will warm to the idea of letting you try her out some time.
 
Yesterday was a good day, out in the SIL'S company once again, she had a mini skirt so short I could almost see her panties, ankle boots with heels and a tight hoody zipped down showing off her little tits, spent a good hour or 2 just in awe of her legs but sadly no upskirt to report, well better luck next time eh.

Damn, she sounds hot! Age?
 
Sil

Have one SIL she stays with us lot, she is a little older than my wife. I have caught glimpse of her bent over, down her blouse, coming out of the shower. Which I have had to go and relieve myself many times right after.
I have many fantasies about her. My wife knows it but tells how bad I am. Still I have them. I think how she would feel on my cock. Like my wife or totally different. I have one fantasy where my wife is sitting on my face while I think she is giving me head at the same time ends being SIL doing it.
She is built like my wife to the point they could almost pass as twins.
 
Before she was my SIL she used to stay at our house sometimes, at the time I was mid 20's and she was 19. We got on well although never really flirted, one night she was stopping over and my wife was working nights. We were sat on the sofa watching tv, when for some reason I started to stroke her arm, she didn't object and I carried on for a while. She then started running her fingers over my leg and before long she was rubbing my crotch. We started to kiss and soon we were both naked on the floor all over each other and had sex twice.

She told me next day that it wouldn't happen again and we should forget about it. Fast forward 3 years and me wife and SIL went on holiday together, my wife was ill one night and went home early leaving me and SIL drinking together. She brought up what we had done previous and asked if I wanted one more go with her. I agreed and we went down to the beach and fucked on a sun lounger.
 
My sister in law continues to be a primary fantasy of mine. I often remember the smell of her panties, the down blouse looks she gives me of her tits and unnecessarily long touches she gives me.

Don't you love it when they give you long, tight hugs even when your wife is around? Mine does that a lot - if no one is looking we do a little grab-ass too
 
Mother-in-Law

I don't have a SIL, but my MIL has been a fantasy for years! I thought I had been playing it cool, but after my wife called me out on all not-so-subtle glances I'd given her (my wife), I am realizing my MIL has probably been on to me from the beginning. Although my wife knows I think her mom is pretty, she definitely doesn't know how often she's been the object of my lust. That said, life has taught me that secrets are never kept, so I am Ok with leaving the lusting to the fantasy realm, rather than actively trying to have a physical encounter.

Some fantastic memories of my MIL:
-Standing in front of her while she's on her knees explaining how to wrap presents for christmas. In retrospect, she must have seen the look in my eye while watching her talk.

-Beautiful camel toe in her tight 1 piece while she lays by the pool reading a book with her legs pulled to her chest.

-Talking with her while she lounged in a pool chair with her jean skirt riding up, and her black and white poka dot panties showing. Amazing full view of her crotch as she spread her legs wide and struggled to get up for dinner. It was obvious what I saw, but she ignored it and acted like nothing had happened.

-A close up view of her ass in tight black yoga pants as I followed her up the stairs to put away luggage.

-Bent over on all fours in tight grey yoga pants while cleaning the base boards.

-Feeling her large breasts against me during tight hugs every time she visits.

-Looking up at her in tight shorts from directly below while she was painting a room. We had a conversation for at least 10 minutes--she had to have known the view i was getting.

Many more, but you get the gist. Despite what I now realize must be obvious lusting to my MIL, she has never overtly flirted with me. But--she hasn't changed her habits either. She still walks around in night gown with no bra while visiting, gives no thought to her positions in a skirt, and constantly sits with her legs spread in tight yoga pants. I can only assume she understands my desires, but doesn't want to act on them.

Brothers wife

My sister in law both travel for work and are in the same city about 3-4 times a year. We both don't mind the trips since we know we don't have to back to an empty hotel room.
