To sniff your mother's p*#$y?

When I was 15 my mom and I moved to a new town. Why is not pertinent to this. We were flat broke when we got there and we had to share a large studio apartment. I had "dropped my rocks" or attained puberty at 11. I was always horny and nearly always had a hard on. One evening I came in and mom was sleeping on the couch, not covered with a blanket just wearing her robe. And it was open. She didn't have any clothes on at all other than the open robe. I looked at her for a few minutes, my penis hard and throbbing. I leaned close to get a good view of her pussy. Then I got even closer and sniffed it. To this day I regret not tasting it. I have always thought she was just pretending to be asleep. Is it normal to sniff your mom's p*&^y?
