Step-Sister's Festival Flames Turn Friends With Benefits

Jake dropped his duffel bag by the front door and stretched, the long drive from campus still clinging to his shoulders. Summer hit him full force the second he stepped inside—the smell of sunscreen, cut grass, and whatever barbecue his stepdad had going out back. Music already thumped faintly from the yard where the festival setup was halfway done. He was home for three months, and the first thing he saw was Riley.

She came around the corner from the kitchen in a cropped red top that barely contained her tits and a denim skirt so short the pockets hung below the hem. Twenty years old now, all long legs and sun-kissed skin, her dark hair messy like she’d just rolled out of bed on purpose. She froze when she spotted him, then her mouth curved into that wicked little smile he’d jerked off to more times than he wanted to admit.

“Holy shit, Jake,” she said, voice low and warm. “College turned you into a fucking snack.” She walked right up, close enough that her bare stomach brushed his arm as she reached past him for a water bottle on the counter. The contact lingered. “Look at these arms. You’ve been lifting.”

Their stepmom called something about guests arriving soon, voice distant from the patio. Stepdad’s laugh boomed outside. Perfect cover. Riley didn’t move away. She tilted her head, eyes dragging down his chest, then lower, shameless.

“You look hot as hell too,” Jake said, throat tight. “Festival girl mode already?”

“Always.” She stepped even closer, hip bumping his thigh “accidentally,” the soft press of her body sending a jolt straight to his cock. “Missed you, stepbrother. Been thinking about you coming home.” Her fingers trailed along his forearm, light, testing. Both of them knew the line. Step-siblings. Parents busy hosting out-of-town friends who were already drinking in the backyard. No one watching. The air between them crackled with everything they’d never said out loud before.
