Let me say this upfront:
I love my wife.
She’s smart, kind, beautiful — everything I thought I wanted in a partner.
So why can’t I stop thinking about her sister?
It started innocently enough. But somewhere along the line, my curiosity turned into obsession. And now I’m stuck in a place between guilt, temptation… and something I can’t quite name.
This is what no one tells you about forbidden attraction — and how it can mess with your head even when you have everything you thought you wanted.
👀 When I First Noticed Her
My wife’s younger sister, let’s call her Jess, was always the “fun one.”
The one with the wild stories, the contagious laugh, the energy that lights up a room.
At first, I thought it was just a harmless crush — like when you meet someone and think, Wow, if life had gone differently…
But the thoughts didn’t fade. They got louder.
More specific.
More intense.
💭 It’s Not Just About Looks
Yes, she’s beautiful.
But that’s not the problem.
The problem is how I feel around her:
More alive. More seen. Less… predictable.
She challenges me in ways my wife doesn’t. She flirts without even trying. And sometimes, I catch her looking at me in a way that makes my stomach twist.
Is it in my head? Maybe.
But the obsession? That’s very real.
😬 The Guilt Is Crushing
You’d think fantasizing about someone else would be easy to brush off.
It’s just thoughts, right?
But when that person is your wife’s sister, the shame hits different.
Every family dinner. Every holiday gathering.
It’s a performance — smiling, pretending nothing’s wrong while my mind runs wild with what-if fantasies I can’t seem to shut down.
And no, I haven’t acted on it.
But the emotional cheating?
That line’s been crossed a hundred times in my head.
🔥 What No One Talks About
There’s this taboo around attraction within families — and for good reason.
It’s messy. Risky. Almost unforgivable.
But here’s the truth most people won’t admit:
You don’t choose who you’re drawn to.
You only choose what you do with it.
🧠 Why It Happens (Psychologically Speaking)
According to relationship psychologists, it’s common for people to develop attractions to their partner’s siblings because:
- Familiar genetics can subconsciously trigger attraction
- The “forbidden” factor increases desire
- Emotional gaps in a relationship make us seek what we’re missing elsewhere
I’m not proud of it.
But knowing the psychology doesn’t make the feelings go away.
😔 What Now?
Some days, I think I should come clean to a therapist.
Other days, I just want the thoughts to stop so I can enjoy my marriage without this invisible wedge between us.
What I do know is this:
Acting on it would destroy everything.
But burying it hasn’t helped either.
