Virgin Stepsister's Passionate First-Time Discovery

Lily stepped into the sprawling family home, her duffel bag slung over one shoulder, heart pounding with a mix of nerves and excitement. At eighteen, fresh out of high school, she was moving in with her new stepfamily after her mom married Jake's dad just months ago. The house smelled like fresh paint and polished wood, a far cry from her cramped apartment. She dropped her bag in the foyer and called out, "Mom? Anyone home?"

No answer. Footsteps thudded from upstairs. Lily's breath caught as Jake appeared at the top of the stairs—her twenty-year-old stepbrother, all six-foot-two of him. He was shirtless, sweat-glistening muscles rippling from what must've been a workout, his broad chest heaving, dark hair tousled. Low-slung gym shorts clung to his hips, and there, unmistakable even from below, was the thick bulge straining against the fabric. He was aroused, the outline of his cock half-hard and twitching as he adjusted himself, oblivious at first.

Lily froze, cheeks burning. She'd seen glimpses of guys in magazines, awkward fumbles with high school boys who'd never gotten past heavy petting, but nothing like this. Jake's body was a sculpted fantasy—rippling abs, powerful thighs, that massive bulge promising something primal. He caught her staring, his green eyes locking on hers. A smirk tugged at his lips, but it softened into something protective, hungry.

"Shit, Lily. Didn't know you were here already." He grabbed a shirt from the banister, but didn't put it on, descending the stairs slowly, eyes raking over her petite frame. She was in cutoff shorts and a tank top that hugged her perky C-cup tits, long auburn hair cascading down her back. Virgin territory, untouched and aching with curiosity.
