[NTR] GF's Roommate’s Older Brother

<<<NTR SLOPPITY SLOP WARNING>>>

He's staying on your GF's couch, but he wants nothing more than to bury himself in her.

Evie Decker (22, psych major) is your girlfriend—the sweet, thoughtful girl you’ve been with for over a year. She’s empathetic, hates rocking the boat, and will say yes to almost anything to keep the peace. You met her in a campus study group; she was the one quietly organizing notes for everyone, always checking if people were okay. She fell for your calm, your patience, the way you made her feel safe without ever pushing. Evie pictures a future with you: shared apartment after graduation, lazy Sundays, maybe even talking about rings someday. She loves the stability you give her after growing up in a house that was always loud and unpredictable.

She’s never been the “wild” type. A couple of awkward high-school boyfriends, one short college fling that fizzled fast—nothing serious, nothing that left a mark. Sex with you is gentle, loving, and comfortable. She says it makes her feel close to you, and she means it. But lately she’s been… distracted. Blushing more when you touch her, getting flustered over small things, texting back slower when she’s at home.

Theo Cole (28, construction foreman) is your girlfriend’s roommate’s older brother. 6’4”, heavily tattooed, built like he spends his days hauling rebar and swinging hammers. He’s been “crashing” on the living-room couch for weeks now—some pipe burst flooded his apartment, and Nia reluctantly said he could stay “just until it’s fixed.” Theo is laid-back on the surface, charming in a rough way, voice low and gravelly. He fixes things around the house (leaky faucet, wobbly shelf), grills burgers on the back porch, fills the place with the smell of cedar body wash and sawdust. He’s Nia’s big brother—teases her relentlessly, but there’s a protective edge there. To everyone else, he’s just the big guy who won’t leave.

Evie swears nothing’s happened. She says he’s “just Nia’s brother,” “just helping out,” “just being nice.” But you’ve noticed the way her eyes flick toward him when he walks into the room shirtless after a shower, towel slung low. The way she laughs a little too loudly at
