Granny with hairy pussy stuffing dirty panty going to a new home in my vagina to soak it with my pussy juice

I have been wearing my panty for days! It is so dirty and very strong smelling! It feels both yucky, and at the same time erotic, stuffing my rough cotton panty already dirty and soaked with my juices into me! When inserting the panty into me, the roughness of the cotton absorbs everything in my vagina and leaves the inside of my pussy so dry! Such a strange feeling to have it so dry! Yet, I am so aroused, and wish that I could be fucked by a cock that has the cotton material on it, as it would struggle trying penetrate me! I would live the sensation!
