Self pleasuring ideas, without buying pleasuring toys?

How I masturbate is just by getting a really thick book or anything like that put it on the floor sit on it with your Vigina on the book and legs bending on each side on the floor and than hump the heck out of it while watching porn. I don't know if this is for everyone but it works for me. Try it but don't do it on floors that are old cause than parents hear and you don't want that.
