Fingering Hairy Pussy With Butt Plugged

I am not sure is she counts as mature or granny but lets say she is mature and the important thing is that she really enjoys fingering her big old hairy ginger pussy and putting small sexy diamond butt plugs in her tight asshole. In my fantasy she would be my nerdy kinky teacher and watching her masturbates would be my reword for being a good boy. What would your fantasy be? What should this bed mommy do to you?
