I'd never expect it to be done to me, and I wouldn't do it. Not open to trying it, either.
I love doing it to a girl who loves it.
I have only had it done to me by two women. The first was short and sweet and we moved on to other activities. The second was heaven. She started with a gentle swipe and watched for my reaction. When I reacted positively she really played to it. Later she was giving me a BJ, reaching down to lightly rub my AH. Then she pushed my legs up to near my face and teased around the AH before diving in. Soon she was tonguing me and I thought I would pass out. It was a sweet time.
If girls enjoy receiving it as much as do, I will gladly perform it anytime.
(I was very clean before we started. I cleaned with soap and water and stuck my finger in to make sure I was clean.)
Do you? I have a question for you. Why would you like the smell of ass? Doesn't it smell like 💩? Wouldn't you taste some 💩 when you lick?
