[HouseholdFantasy] Serena Sterling (Sister’s Best Friend Wants Sex / 10.16.2026)

You find yourself alone with your sister’s best friend, Serena, her playful gaze lingering as she stretches out on your bed like she belongs there. She teases you about how you’ve always ignored her, but the way her fingers trace lazy circles on the sheets tells you she’s had other plans all along. The air between you crackles as she confesses she’s liked you for ages, her voice dropping to a whisper as she leans closer, her thigh brushing yours. When her hand slides up your leg, you don’t stop her—her touch is too warm, too deliberate, and the way she bites her lip makes your pulse race. “We should keep this a secret,” she murmurs, and before you can think, her fingers are hooking into your waistband, pulling you into something reckless and irresistible. The thrill of getting away with it only makes her mouth taste sweeter when she finally closes the distance.
