I don't know the name, i only have a hazy memory of it as it was a long time ago.

This is what I think happened.

Firstly, the main character is a girl. Her brother went out for the day, or so she thought he did. So she decided to do some mischief, she put a bullet vibrator on with a timer and rope bondage. She also tied up her arms. Suddenly, her brother came back, she panics and hides under the bedsheets. Her brother comes into her room asking why she's in the bed, she says shes sick. The vibrator timer times out and starts, but likely the phone rings and brother leaves the room.

Brother comes back and finds out her mischief.

Some extra details that I'm not sure of are that she's wearing glasses, brother came back early cause he only bought some cd, shes wearing overalls
