Sunlight slanted through the tiny laundry-room window as Sophia sorted the overflowing hamper. Downstairs the renovation crew hammered away, but up here the house felt eerily quiet—except for the soft, damning rustle of lace in her hands.
She'd been missing pairs for weeks. At first she blamed the dryer. Now she knew better.
She pulled out the tiny red thong she'd worn two days ago. The one she'd tossed in after her shower. It should have been clean.
It wasn't.
The crotch was still warm. Slick. Absolutely painted with thick, glossy white streaks—fresh cum, rope after rope of it, still dripping slowly onto her fingers. The scent hit her hard: salty, musky, young, potent. Unmistakably male.
Sophia's breath caught.
She held it up to the light. Another fat glob slid down her wrist.
Her thighs squeezed together on instinct.
The black bikini from yesterday was worse—saturated, crusty in places, still wet in others. Whoever had used it hadn't just jerked off. They'd rubbed it against something soft and dripping. Something that wasn't a hand.
Her pulse raced.
She dug deeper. More of her panties than should have been there. The expensive lace thongs Alex always "accidentally" brushed against when he helped with laundry… now back, suspiciously clean except for fresh loads smeared across the crotch. She counted. Twenty-three pairs this week. She only owned eighteen.
Three extras. All of them ruined with her stepson's cum.
Sophia brought the red thong to her face and inhaled slowly. The smell flooded her—familiar, intoxicating. She'd caught hints of it on Alex's sheets, on his gym shorts, in the steamy air after his long showers.
Her stepson.
And the way the fabric was stretched… it had been wrapped around a thick, throbbing cock. Multiple times.
She should have been furious.
Instead, her free hand slipped under her thin robe, pressing two fingers against her suddenly soaked pussy.
"Mmm…" she breathed, eyes fluttering. The image burned behind her lids: Alex stroking himself, pumping load after load into her panties while thinking about her. Maybe even while someone watched. Or helped.
She rubbed the sticky crotch of the thong directly against her clit through the robe, smearing her stepson's warm cum onto her own folds. A soft, needy moan slipped out before she could stop it.
Then she heard it—giggles from upstairs. Alex's low groan. Mia's bratty laugh. The faint, rhythmic creak of the bunk bed frame.
Sophia's lips curled into a slow, dangerous smile. Not angry. Not shocked.
Predatory.
She folded the ruined red thong neatly, tucked it into her robe pocket like a trophy, and whispered to the empty room:
"Oh, you two naughty little rabbits… Mommy sees everything now."
She glanced at the clock. Crew gone in an hour. Dad still in Singapore for weeks.
Sophia licked a stray drop of cum from her fingertip, savoring the thick, salty taste, and started up the stairs with that same calm, knowing smile growing wider.
Time to check on her stepchildren.
And see exactly how deep in trouble they really were.
