Ass licking kink
I love 69 very much. Once while my wife and I were doing 69, her big beautiful brown ass was right in front of my eyes. I sniffed her asshole and found that smell intoxicating. At last I couldn't resist and put my nose on her asshole. What a feeling that was! She moaned and said, 'tu ulte kaam mat kar' (don't do bad things). But I could feel her enjoying whatever I was doing. Finally I put my tongue deep inside her asshole and started licking it aggressively. Her moans got louder.
When I finished sucking her asshole, she said, 'chhi' (eww). I became conscious and thought about what she might be thinking. But to my surprise, she kissed me on my lips and nothing has felt hotter ever since. Now I lick her ass regularly and it has become a ritual for both of us.
