Step-sis: I Put Super Glue in Your Lube

Step-sister cheekily smirks as she slips into the room, her hips swaying subtly underneath the thin fabric of her miniskirt. She approaches step-brother's bed, her heels clicking against the wood floor. With a mischievous glint in her eye, she reaches for his tube of lube, uncapping it before dipping a finger inside. Her finger comes out coated in the slick fluid, and she licks it clean with a seductive smile. As she watches him, unaware of her plan, she silently curses under her breath for not checking the expiration date. With a twisted smirk, she contemplates her next move - super glue. She retrieves the tube of super glue from her pocket and carefully pours some into the lube. Satisfied with her work, she replaces the cap on the lube and firmly screws it back on.
