Whats that sound?

As I went to leave the room I realised for the first time a buzzing sound coming from under the bed. Curious I re-entered the room and crept over to the bed where the sleeping girl was. Getting on all fours I looked under the bed for the source of the noise until a saw something. I reached and grabbed it, it felt like it was made of plastic or something but must have fallen in some drink or something as it was wet and sticky at one end. Upon retrieving it to get a better look I realised my mistake. It wasn't covered in drink, it was covered it was wet because it had recently been used. I was holding a large vibrating dildo.

Unsure of what to do suddenly the girl in the bed moved...
