Step-Sister’s Forbidden Bedroom Mirror Masturbation

The house was too quiet. Jake had spent the first hour of the empty weekend pretending he wasn’t thinking about her. Riley had stayed behind while their parents left for the lake house, claiming she had too much studying to do. He knew the real reason: she liked having the place to herself. She liked her bedroom door shut and her rules respected.

But rules had never stopped the low, constant ache he felt every time she walked past in those tiny sleep shorts.

He was on the couch scrolling mindlessly when he heard it.

A soft, breathy sound drifting down the hallway. Not quite a moan. More like the start of one. The kind that slips out when someone thinks they’re alone.

Jake’s head lifted. His pulse kicked hard.

He told himself he was just checking. Making sure she wasn’t hurt. The excuse tasted like bullshit even before he stood up.

Bare feet silent on the hardwood, he moved down the hall. Riley’s door was closed, but not completely. A thin black gap showed between the frame and the edge of the wood. The moans were clearer now, rhythmic, wet. The unmistakable sound of fingers sliding through soaked flesh.

His cock thickened instantly inside his sweatpants.

Heart hammering against his ribs, Jake set two fingers against the door and eased it open another inch.
