Girlfriends Sister

[Bradbury42]

Does anyone else have an experience of anything happening with their partners or wives sister? There been a few things happen to me lately that I'm not sure what to make of.
I'm 25 and I've been with my girlfriend for over 3 years now and she has a younger sister who is 21. I've always got on with my gf's family and her sister in particular as we're quite similar in many ways. Around 3 months ago, she split up with her partner, and she's now living on her own and has 2 kids both under 4, so we do what we can to help her out. My gf however started a new job where she works away Monday to Thursday, so I've been going over myself, helping with little jobs she needs doing, or watching the kids while she cleans up or baths etc.
It's nice as we've gotten closer as after the kids go to bed we'll have a cup of tea and a chat and have become really comfortable with each other.
When i was first going there if she had a bath she'd come back in fully clothed, but as times gone on she often wears little pyjama shorts, and sometimes comes in to make the tea in just her towel. It's bad to admit but she's a very attractive girl. She's quite tall, naturally slim, but has quite big boobs. Overall a very nice body. And I've found myself looking at her when she's in her towel, imagining what's underneath. And i think she must of caught me looking a few times because she'll sometimes smile at me like she knows, but hasn't said anything.
Another time she was in her pyjamas and went out for a cigarette on her balcony, when she came back in her nipples were hard and almost visible through her top. And this definitely made me look!
There's been a lot more happen recently, but was wondering if anyone else has anything similar happen? Any advice before I share the rest of my story

Be careful. As someone once said, "Don't swing on more than one limb of the family tree!"

Sisters can be very jealous and competitive....

Like all gambling opportunities, don't play unless you are prepared to lose everything that you are risking. My instinct says the sister is ready to try something, but she might change her mind in midstream. Even worse, she might have some sort of old grudge or unconscious competitive urge that makes her want to blow up her sister's life and maybe even end up being your new girlfriend. Best case scenario: you get to fuck the sister and your girlfriend finds out and doesn't care (not impossible and, unfortunately, rare). Next-best case: you get to fuck the sister and your girlfriend never finds out (More likely, but requires a lot of luck and the sister willing to keep a secret forever.) MOST likely case: you get to fuck the sister and your girlfriend finds out, gets furious, dumps you and the sister also blames you and never talks to you again. Worst case: you make a move, the sister tells you that you are an asshole, tells your girlfriend and you end up alone with no new sexual memories.
So, good luck in making up your mind. The only absolute safe course is to enjoy the peeks and uninvited sexy stuff the sister is doing while you do nothing about it but look and burn it into your brain.
Let us know, please, if new good stuff happens!

It's very dangerous territory. The bottom line is that even if you do it and then fall in love with the sister and she with you, the rest of the family will never accept it. And the chances that you will be able to have the sister and no one will ever find out is...VERY small. Are you ready to adopt her two kids?

The sister is a young, horny girl. She will soon find a boyfriend and then you and she can be platonic friends more easily

Thanks guys. You all make a lot of sense. But it's not that i would want anything to happen. But it seems to be getting to the point where i might have a chance to see her naked, and I would quite like to see that! Maybe i could find a way for it to be an "accident" that i see it?

She is single, 21, and has 2 kids under 4! How would you like to be baby-daddy to number 3?

Be careful! A very dangerous game with a sister staged.

This is tricky. She could simply be getting more comfortable around you, or she likes to see how much you are going to stare and what you are going to try but has no intention of doing anything (this is the most likely scenario), or your gf has talked to her and if you make a move there are threesomes in your future (least likely scenario, but it's fun to dream).

It COULD be any of those, but don't be silly and ruin everything unless you know for sure. If your gf, your sister, and you are all in the same place at the same time and the sister comes out in a towel or pjs without a bra and sticks her hard nips in your face, see what clues your gf gives you, and only THEN you might have an answer.

Given she is 21 with two kids already...she probably just wants to screw you and it's not going to go well for anyone involved. I grew up around these types; it's my own background until my mid-20s, so I see it from a mile away.

Having had decades of ambiguity among my wife, her sister, and myself, it's not worth the risk unless you are more certain.
