Fingering Always Does It

I start off taking all my clothes off except my panties, and I get under the covers. I love the feeling of my sheets on my bare skin. I love to just play with my pussy with my hands. I rub my middle finger up and down my clit, then I go fast then slow it down. This gets me ready to almost burst but I like to tease myself. Finally when I'm ready I go really fast while pinching my nipples. This gives me a good orgasm everytime.
