Every sunday evening I have a plunger aside from my towel closet which is hidden from my parents, because it might still be wet and smell like my pussy if they find it. Also I don't want them to ruin it/use it for its real purpose. I use the handle of the plunger and sometimes stick it in anally/vagina. Just to get started. Then, once my pussy is hot and wet I start plunging and using it as a suction cup on my pussy. It gave me one of the most sensual masturbation experiences ever.
And make sure not to use a used one :S
