I believe them to be her dildos, although just a guess. If I had my druthers I would keep my "a machines" or favorite toys at the ready at all times, thus out in the open on the table. Whereas I'm sure she would have both favorite and backup devices or in this case "machines", the later would be tucked away securly in a drawer. These b machines would not have to be at the ready beause they are mostly used for emergency applications,ie; batterys going dead from overuse, mechanical failure, or just plain absent minded loosing of the dildo. This is just a theory however.
