Increasing Feelings For My Sister-in-law

My wife and I have a happy enough marriage of 10 years, but for a long time I've been wrestling with my secret and growing attraction to her sister.

We text daily and exchange photos of what we're doing. Sometimes we send selfies, and sometimes they get a little revealing.

My sister-in-law fills a void that is present in my marriage. We have made love a few times, mostly quickies at family gatherings, but last weekend we had a proper date while my wife was away.

Increasingly I feel I married the wrong girl and life is passing me by. What should I do?

Sis-in-law is married (to someone else, alas). Both families have kids under 5. I think they'd be too young to notice much change if suddenly their aunt became their mom or their become uncle be their dad.

My brother in law (husband's older brother) has always been affectionate towards me since I was married in to their family. He was little bit flirty (non-sexual way) from the beginning. It actually made me relaxed and less tensed around my in laws. He was single at that time and got married few years later. And he became less flirty and distant. I suppose it was because his wife was much younger and having insecurity and jealousy.
We both are now married 25+ years to our respective spouse. I have two grown kids. He has three, two grown, one teen.
But last 7-8 years, we reconnected and he was his usual flirty self. We started texting and flirting. We secretly sent selfies and sometimes they get bit revealing. During family gatherings we snuck away and found some alone time to fool around.
I love how he touches me, played with my breasts and fucked me. My husband couldn't ever made me feel that way. I also feel like I married the wrong brother.
But now we are older and too long married to our spouses and having grown up kids, that I don't think it'd work out the way we'd like.

Dont leave your wife for her. It never works out well. Now, if you all divorced, waited awhile, then were above boars with everything, then you may have a chance of salvaging all the various relationships in the family that would be destroyed. Stop thinking with your dick and really consider what you are doing and expecting out of your affair.

anon1, how wonderful that you rekindled your relationship with your husband's brother! Don't count out making a change later in life. You and he might yet enjoy some beautiful years together!

anon2, I appreciate your sage advice. Does being honest and authentic have to destroy my relationships? I don't want to assume that my wife can't handle it. After all, she and her sister love each other. My wife would want her sister to be happy.

There's also the reality that my feelings toward my sister-in-law are just too far gone. That's a genie that can't be put back in the bottle, no matter how hard my wife rubs Aladdin's lamp!

My advice is tread carefully, here! Part of what makes cheating with your bil or sil so sexy and so enjoyable is the added risk involved! Tasting the forbidden fruit makes it so much more exciting.
However, if you leave your spouse and hook up with your in law, it may not go well. Your spouses will be pissed. They have spent decades building a life, sacrificing and planning for a life long love and you will have destroyed it! Think about it. As of right now your spouse believes that they are happily married. They probably wouldn't mind a few changes in the couple dynamic, but all in all, she believes that the two of you are together for long haul. Now, tell her that you've been fucking her sister and are planning on leaving her. She how fast the talons come out. Best of luck!

I have been sleeping with two of my wife’s sisters for a while now. I know it’s wrong, but Im addicted to it. Yes, they both know about the other.
