Wife's sister getting inappropriate?

Question

So me and my wife have been married almost a year now. We're both 21 and we started dating at 16 years old. My wife's sister is 19 years old.

I've always got on with my wife's sister as she is a nice person, but about a month ago, she started flirting with me whenever my wife wasn't around. She started off with subtle comments like "ooh you must lift heavy weights at the gym" whilst giving my arm a quick stroke. Then she started flirting more with comments about me being good looking and my wife being a very lucky girl. She laughs a lot at my jokes and recently I told a few shitty jokes on purpose just to see her reaction and she still laughed like I was some kind of world class comedian.

She even asks me whether I think she looks good in her outfits and then starts shifting her body in sexy poses and stretches her legs and feet and things like that.

2 days ago was the strongest hint yet that she's flirting with me. So me, my wife, her sister and my brother were hanging out and eventually my brother went home so it was just the 3 of us. My sister-in-law was staying over. We put on a movie and eventually my wife dosed off in my arms whilst cuddling and she started saying how much she wants a boyfriend in her life to cuddle with. Then about 10 minutes into the convo my wife woke up and went to bed as she was tired. Her sister then became much more open and once again mentioned wanting a boyfriens in her life. I felt as though she was trying to make a move on me as she kept rubbing her feet on me and she also kept asking me whether I like her painted toenails. I was worried this was getting too bad and said that I was tired and I offered to sleep on the couch so she could sleep in the bed with my wife as we were living in a 1 bedroom apartment...

I love my wife to pieces and would never even consider cheating on her. I just feel her sister is trying to make a move on me and I don't know what to do about it...

You need to tell the sister to back the fuck off. That's completely inappropriate behavior and a whole other level of messed up. Who tries to have sex with her sisters husband. 🤦‍♀️
If you're concerned with her turning around and lying to your wife then I think you should set her up. Sounds kind of shitty I know but this is a no win situation and if I were in your place I'd do what I could to cover my own ass.
Use the recording app on your phone and tell the sister how much you love your wife and I'd list a few of the more uncomfortable moments to the sister telling her that these things are not ok. Then tell her you want it to stop. I wouldn't necessarily let your wife listen to it unless it was a last resort but I think it's a good back up should it come to that.

Why aren't you telling her to back off? Put some bass in your voice and let her know that she needs to stay in her lane and then tell your wife

Talk to the sister. Tell her to stop. If she doesn't, warn her once and then tell your wife. If you don't trust the sister, just tell your wife and let her handle it.

Tiaroendu479 · Answer

It honestly sounds like she’s really lonely and is projecting those feelings onto you, which is totally inappropriate. Talk to your wife about setting her up with someone, that way you don’t have to directly confront anyone and the situation is solved a little bit.
Also, try to avoid situations where you’re alone with her

Tell her the comments are inappropriate and avoid being alone with her. If it gets outstanding, tell your wife and all three of you sit and discuss.

Izumiblu · Answer

You ignore it and hook her up with your friends or brother.

Psychoanalytical · Answer

If I was in your place, I would start putting limits to the sister.

Try to be a bit rude whenever she tries to flirt with you. Show her that you are unhappy with her behaviour. Show her that her behaviour is heavily rejected.

She will back off when she feels rejected by you.

Don't tell your wife, this will cause issues between both of them. Just do your part and don't let her cross the lines anymore. Be formal! Be serious! Be blunt! Don't be too kind with someone like her. She didn't respect her sister, she deserves a little bit of rudeness in my opinion.

Ice it with the sister. Just turn cold whenever she starts with the flirting. But never tell your wife. It will hurt her to the core that her sister was so disrespectful. ~JSmith

You need to tell her you feel this way. Don’t tell your wife yet though bc that is her sister and she might never forgive her. If it continues after you tell her to stop then tell your wife and tell her how you tried to handle it but she wouldn’t stop.

Why TF don't you want to tell your wife about it? She'll handle it better. Don't start off in an accusatory note. Be nice, try telling her how uncomfortable you are with your sister-in-law. Maybe you could also tell her that you want to be alone with her, and not share your apartment with your sister-in-law?

legman528 · Answer

I would tell your sister-in-law exactly what you said in your second-to-last sentence. If she persists, you need to tell your wife how she is acting. I wouldn't be alone with her just in case she tells your wife you were coming on to her, in order to defend herself.

BigAl1982 · Answer

Just hook her up with one of your single friends. Problem solved.

jakeforfun · Answer

Say something like "Maybe I'm crazy, this is weird, and I must be imagining it, but your sister...", and tell her everything. See what she wants to do. Be honest with your girl. Don't hide a smidge. Put the ball in her hands, so to speak.

TheSpaceGnome · Answer

Record her hitting on you, tell her to stop, tell your wife that her sister is being rude and you need help getting her to stop.

DiegoO · Answer

Get her a boyfriend. Present her to one of your friends or your brother. If it doesn't work, may God save your marriage.

It is normal, some girls have special relationships with the husband of her sister, that may be sisterly love are some of them have sexual relationship with their brother in laws. If both are consensual then no problem.
