Scenario

Sam thought the house was completely empty that Friday afternoon—Mom at work, Dad on a golf trip, and her big step-brother supposedly out with friends until late. Perfect. She’d been waiting all week for this moment of total privacy to try on her latest knitting project: a handmade Virgin Killer sweater in the softest tan cashmere blend she could afford.

The design was shamelessly sinful, every stitch poured with secret fantasies. From the front it looked almost innocent—a deep plunging halter neckline that hugged her perky C-cup breasts like a lover’s hands, the fuzzy knit so thin her stiff nipples poked through visibly, no bra allowed. The halter ties crossed delicately behind her neck, leaving her shoulders and collarbone bare. But the back… oh god, the back was pure temptation. Completely open from neck to lower back, the fabric dipped dangerously low, exposing the elegant curve of her spine, the cute dimples just above her firm, round ass, and stopping high enough that half her cheeks peeked out teasingly. The hem barely skimmed the tops of her thighs, turning the whole thing into the world’s most dangerous mini-dress.

She stood admiring how the luxurious yarn felt against her sun-kissed skin—like warm silk brushing her most sensitive places. Her long blonde waves tumbled over one shoulder, hazel eyes sparkling with mischief as she bit her plump lower lip. Paired with nothing but a tiny black lace thong that disappeared between her cheeks, she looked like pure forbidden fruit.

“Who knew my silly little knitting hobby might actually get me laid,” she whispered to herself, a flush creeping up her freckled chest.

Because every late-night stitch session, every careful row, had been fueled by him—her tall, broad-shouldered, infuriatingly hot step-brother who’d moved back home after graduation. The one with the deep voice, tousled dark hair, gym-built arms, and that responsible, mature vibe that made her stomach flip. She’d been crushing hard since their parents married years ago, but having him under the same roof again had turned quiet fantasies into an obsession. Stolen glances in the kitchen, “accidental” brushes in the hallway, the way his eyes sometimes lingered on her yoga shorts… it was only a matter of time before the tension snapped.

Now, alone and dressed like this, the daydreams flooded in. She imagined him coming home early, walking in, seeing her like this—eyes darkening with hunger, finally giving in to what they’d both been pretending wasn’t there. Her breath hitched. One hand trailed down her flat stomach, slipping under the delicate waistband of her thong. She was already soaked, smooth shaved lips slick as she parted them and circled her swollen clit slowly, deliberately.

“Mmm… big bro,” she moaned softly, hips rocking against her fingers as the fantasy sharpened—he’d pin her against this very bed, rough hands gripping her exposed hips, spanking her bare ass for being such a tease, whispering how long he’d wanted his naughty little step-sis…

Her free hand cupped a breast through the soft knit, pinching her nipple until it ached deliciously. Thighs trembling, sweater riding up even higher, her cheeks flushed crimson, lips parted, ass arched out invitingly. Faster now, chasing that edge, so close, so fucking close—

She never heard the front door open downstairs.
