Mom is doing work at home, I'll have to give her a hand

Mom is doing work at home so I went over to give her a hand, damn, she helped me with my move and now I feel like a pig if I don't give her a hand but as soon as I arrived something happened to me that made me remember why I haven't I went before to help her..., she was standing on a ladder and was only wearing a thong, damn, how can you concentrate with something like that? Normally, the first thing I did was touch her ass, that perfect ass to see if it was real and I see visions every time I am near her.
