Mom hanging out naked at home

After loosing my job and 3 months without finding a new one I also lost my rented apartment, so my only solution was to accept my mother's invitation to go to her place until I could stand on my feet again. My mother loves to be naked around the house and since she started to leave alone she does it immediately every time she gets home. At first it was weird but with time I got used to it and some times I even join her. She only gets upset when I ask her to show me more, but sometimes I get lucky...
