Saw my friends mom naked

Okay one time I was walking through my friends house and he drove to the store so only his mom and I were at his house. It was late and I had to use the bathroom, on the way back to his room I glanced into his mothers bedroom and she was passed out in a thong with her ass in the air the edge of her bed? I stood there for a second thinking, then I walked in to get a better look, she had been drinking so I wasn't worried about her waking up so I got as close as I could to her ass, I looked very closely at her butthole and asscrack, I mean my face was literally inches from her ass and I could smell it, it was clean too. Anyway, very carefully I pulled her thong to the side and extremely closely examined her shaved vagina and clean pretty butthole. As I was putting the thing back into place I snuck a quick swipe from pussy to back. Then I carefully for a split second touched my tongue to her butthole and she moved a little so I stopped and went into the bathroom and jacked off. IIN?
