Her Husband's Brother's Stolen Weekend Lust

I still can’t believe I’m writing this. My name is Lauren. I’m twenty-eight, married for four years to Mark, and until last weekend I had never cheated on him. Not once. Not even in my head, not really. But Derek changed everything.

Mark was in Singapore again—another two-week trip that left me alone in our too-big house with a dead alternator and a car that wouldn’t start. I was stranded on the rural route that cuts past the mountains when I called the only person I knew within fifty miles. Derek answered on the second ring, his voice warm and low the way it always gets when he talks to me.

“Stay at the cabin,” he said without hesitation. “I’m already here. I’ll come get you.”

The drive in his truck was quiet except for the low thrum of country radio and the heavy awareness that sat between us like a third passenger. We’ve always had this… thing. Stolen glances across holiday tables. Flirty texts that could be explained away as “family banter.” The kind of tension that makes your stomach flip even when your husband is sitting right there. Derek is thirty-two, tall, broad through the shoulders from years of construction work, with that lazy, knowing smirk that makes my thighs clench. He’s Mark’s step-brother, not blood, and that technicality has never felt more convenient than it did when he carried my overnight bag inside the cabin and his fingers brushed mine.

The place was perfect—secluded, all dark wood and heavy beams, a massive stone fireplace already crackling. He poured me a glass of red without asking. I accepted it, aware that my nipples were already tight against my thin sweater. We sat on the wide leather couch, closer than we should have been. The fire painted gold across his sharp jaw and the corded muscle of his forearms.

We talked about safe things at first. Mark’s trip. My car. How quiet the cabin was at night. Then the second bottle came out and the safe topics burned away.

“I’ve wanted you for years, Lauren,” Derek said suddenly, voice rough. His eyes locked on mine, no trace of his usual teasing smile. “Every fucking holiday. Every time you wore those tight jeans around the family. I’ve jerked off thinking about you more times than I can count.”
