Spencer Reid

Your life had taken an unexpected turn when your dad married Spencer’s mom. It was a surprise—your father, a straightforward, no-nonsense man, falling for Diana Reid, a woman with her own set of struggles. They had met at an academic event and hit it off in a way that made even your pragmatic dad soften. Diana was kind and loving, despite her mental health issues, and your dad’s devotion to her had been touching. You were fine with the marriage. But Spencer? That had been the real surprise.

You’d heard about Spencer Reid—the genius FBI agent, the man with an IQ off the charts and an eidetic memory. But the reality of living with him was different. He was shy, awkward, and often distant, more absorbed in his books than in the world around him. Meeting his gaze for the first time had been a challenge, and conversation between you two had been rare. Still, you’d grown used to his quiet presence, his bookish routines, and the way he moved around the house as though he was never fully present.

Over time, though, something shifted. The unspoken understanding between you two deepened. Spencer’s routine comforted you, and your presence seemed to bring him a quiet sense of ease. The tension between you was subtle, mostly in the form of innocent light flirtations—small gestures here and there, nothing too serious. It began with little compliments, the way Spencer would brush past you in the kitchen or how his hand might linger on yours for just a second too long when passing the salt. You shrugged it off, trying to convince yourself it was all in your head. But recently, those moments felt more intentional, leaving you both lingering in the awkward space between sibling roles and something else entirely.

When your parents announced they were going away for their anniversary weekend, leaving you and Spencer alone, you hadn’t thought much of it. But as soon as they were gone, something shifted. The house was too quiet, amplifying the awareness you already had of Spencer. He was sitting on the couch, a thick book in his lap, reading glasses perched on his nose. His brow was furrowed in concentration, and his fingers absentmindedly turned the pages, but you couldn’t help but notice how attractive he looked sitting there, oblivious to how much space he took up in your thoughts.

You tried to dismiss the feeling—it was ridiculous, right? He was your step-brother now, and you had to keep it together. But the quiet house made the tension between you more palpable, the brief touches and stolen glances from before hanging in the air like a secret waiting to be spoken.

Spencer glanced up, catching you staring at him. His eyebrows raised slightly, a small, awkward smile tugging at his lips before he quickly looked back at his book. You turned away, pretending to be absorbed in your phone, but your heart raced. It wasn’t the first time you’d been alone with him, but tonight, without the buffer of your parents, everything felt different. The space between you wasn’t just physical—it was charged with an unspoken attraction that neither of you had dared to acknowledge. You weren’t sure if it was all in your head, but when Spencer shifted uncomfortably, clearing his throat, you wondered if maybe he felt it too.

“You’ve been awfully quiet,” he remarked softly, a slight teasing lilt in his voice. You smirked, feeling a flutter in your chest. “Just trying not to disturb the genius at work,” you quipped, your eyes catching his. Spencer chuckled, the sound low and soft, but his gaze lingered, scanning your face for a beat too long before he spoke again. “I don’t mind a little distraction,” he said, his voice almost playful, as if daring you to push that line a little further. The words hung in the air, charged with the same undercurrent that had been building between you for weeks.
