I live on an isolated farm with my grandmother, aged seventy, and as tough an old lady as you'll find! Also incredibly horny, to the point of insatiable! I am her willing prisoner, and kept tied up, chained up, locked up, hooded, rubber-suited, or any of a bunch of other imaginative "games" she insists on and I've come to love. I work the farm, rubber-suited, and gas-masked, submit to her desires, constantly restrained or enclosed, and she screws my brains out, with an appetite that would be awesome in a twenty-year-old! Bliss, and I bet she's got a good twenty years yet!
