The secret has lived in my chest like a parasite, feeding on every moment of our brotherhood.

The Invisible Thief of Love
I stole my brother's girlfriend, and he never knew why she left him. For years, the secret has been a gnawing rot in my gut, a slow-acting poison that tainted every shared laugh, every family dinner. He still talks about her sometimes, wonders what went wrong, and I just nod, offering hollow platitudes while a chilling wave of guilt, mixed with a strange, dark triumph, washes over me.

It started subtly, innocently enough. Mark, my older brother, brought Amelia home during a summer break from college. She was a whirlwind of bright smiles and infectious laughter, with eyes that sparkled like the first morning dew. Mark was head over heels, and it was obvious why. Amelia was beautiful, intelligent, and genuinely kind. I liked her instantly, but that liking quickly morphed into something far more dangerous, something I ruthlessly suppressed.

I was the younger brother, always a step behind Mark. He was the golden child – smarter, more athletic, effortlessly charming. I lived in his shadow, comfortable there, but also resentful. He got the scholarships, the lead roles in school plays, and now, he had Amelia. A part of me, a small, ugly part, couldn’t stand it.

They were inseparable that summer. Movie nights, long walks in the park, quiet evenings on the porch. I was often the third wheel, invited out of politeness, or perhaps, because I made Mark feel even more confident in his happiness. I’d watch them, feigning casual disinterest, while inside, a perverse desire twisted my gut. I wanted what he had. I wanted her.

The turning point came one sweltering afternoon. Mark was at his part-time job, and Amelia was helping me fix a flat tire on my bike in the driveway. Sweat beaded on her forehead, a stray strand of hair clung to her cheek, and she laughed when grease smeared on her nose. She looked effortlessly beautiful, even covered in grime. I handed her a wrench, our fingers brushed, and a spark, undeniable and electric, shot through me. Her eyes, briefly, met mine, and there was a flicker there, something beyond mere friendship, before she quickly looked away.

That flicker was all the permission I needed.

I started small. Little acts of kindness for Amelia when Mark wasn’t around. Picking up her favorite coffee, offering to help with errands she had, listening intently when she talked about her dreams – things Mark, absorbed in his own college anxieties, sometimes overlooked. I made myself indispensable, a safe, comforting presence. She started confiding in me about minor frustrations with Mark – his occasional forgetfulness, his intensity. Nothing major, but enough to plant tiny seeds of doubt.

Then came the late-night texts. Innocent at first – a funny meme, a shared article. Then they became more personal. Thoughts she couldn’t share with Mark, worries about her future. I became her confidant, her emotional sounding board. I knew I was crossing a line, but the thrill was intoxicating. The thought of stealing something so precious from Mark, the perfect brother, filled me with a twisted sense of power.

One night, Mark was out late with his college friends. Amelia was alone at their apartment, feeling unwell. I "checked in" on her, bringing soup and medicine. The conversation flowed easily, intimately. The unspoken tension between us was thick enough to cut with a knife. As I was about to leave, she reached out, her hand gently touching my arm.

"Thank you, Daniel," she whispered, her eyes dark and vulnerable in the dim light. "You're always there for me."

In that moment, all my carefully constructed restraint shattered. I leaned in, and she didn’t pull away. Our lips met, tentative at first, then urgent. It was a stolen kiss, filled with a dangerous thrill and the bitter taste of betrayal. She broke it off, her eyes wide with shock, but also… something else. Something that told me she felt it too.

The next few weeks were a blur of stolen moments and whispered conversations. We told ourselves it was wrong, that it had to stop. But neither of us truly wanted it to. The guilt was immense, a constant companion, but it was overshadowed by the intoxicating rush of forbidden desire. I saw the signs of her pulling away from Mark – more arguments, less enthusiasm, a growing distance. He was confused, hurt, blaming himself. He confided in me, his brother, asking for advice, wondering what he was doing wrong. And I, the snake in the grass, offered sympathetic words, secretly fueling his despair.

Then, the ultimatum. It came from Amelia. She couldn't do it anymore, the lying, the sneaking around. She couldn’t be with Mark knowing what she felt for me, knowing what we had done. But she wouldn't tell him the truth.

"He'd be crushed," she said, tears in her eyes. "It would destroy him."

So, she simply ended it with him. A quiet conversation, a tearful goodbye. Mark was devastated. He didn't understand. He pleaded, he begged, but she was resolute. She moved out, back to her parents’ town, ostensibly for a "fresh start" before her senior year.

I watched my brother crumble. He stopped eating, lost weight, his grades plummeted. He spent nights staring at the ceiling, replaying every moment, every conversation, searching for the crack, the flaw, that had caused Amelia to leave. He blamed himself, blamed college stress, blamed the distance. Never once did he suspect me. Never once did he suspect his own brother, the one who had offered him a shoulder to cry on, the one who listened patiently to his heartbroken laments.

And I let him.

The twisted part? For a while, Amelia and I continued our affair, albeit long-distance, clandestine. The guilt was immense, but so was the pull. But the secret, the original sin, had already soured everything. The thrill faded, replaced by a constant anxiety. The stolen love felt tainted, brittle. Eventually, we drifted apart, our connection unable to thrive under the weight of such a lie. She found someone else. I stayed single, unable to form a genuine connection, always feeling like an imposter.

Years have passed. Mark eventually recovered, found someone new, got married, and has a beautiful family. He’s happy. Genuinely happy. And sometimes, when I see his genuine joy, a pang of something akin to true remorse hits me. He has no idea that his first great heartbreak, the one that shaped so much of his early adulthood, wasn't just bad luck or a change of heart. It was a calculated act of sabotage, orchestrated by the person he trusted most.

I go to family gatherings, sit across from him, listen to his stories, and offer advice as his younger brother. He still trusts me implicitly. He still tells me I'm the best brother anyone could ask for.

And in those moments, the rot inside me grows a little deeper. The silence is deafening, the secret a heavy, unbearable weight. I stole his love, his innocence, and his peace of mind, all for a fleeting, poisoned taste of triumph.

And he never knew.
He still doesn't.
And I’m too much of a coward to ever tell him.
