I Showed buttcrack after a while

The other day, after months, I went to the library with a pair of shorts a size too big and a high shirt. When I arrived, I went to the kids section and see if I could get a peek of a parents crack but I didn't get any so I untied my short's laces and went to get a book ok the lower shelf in a normal aisle. As I crouched I had only about one inch showing and there was nobody near me in that moment but this was just the start because I decided to leave the book and walk around a bit. When I felt my shorts ride a bit lower, I crouched down again to get a book and this time about 3 inches showed, I stayed crouched for about 30 seconds (enough to catch the attention of a fine black chubby woman. Probably about 23yo). I felt she was staring at me so I decided to stay those 30 seconds instead of my usual 10. When I got up I saw her turn her head around very quickly and made my way to a chair close to her with the book I grabbed. I picked a chair that had an open back and that was set in a way that my back was in the librarian's view. I sat down, bended forward a bit, my shirt rode up, and my perfect 5 inches were showing. I couldn't tell if the librarian was staring or not so I got my phone, lowered the brightness to minimum and opened the front camera. Turns out she wasn't looking, but a few seconds later I saw her glance a millisecond then take a second long look. Also, the chubby 21 yo woman walked behind me staring and went to sit on a chair behind me. To show even more (because atp they were really interested), I grabbed my pen and notebook, dropped them, got up, bended over and squatted a bit, showed them 80% of my naked ass including a bit of asshole, got back to sitting and was basically showing my fully naked ass to them since I was kinda leaning forward. Looking at my phone I saw the chubby lady pull out hers and take a few pictures, maybe a vid so I did my encore, dropped my pen again, under the table so I had to get on all fours and showed a bit of asshole, then left. They sure as hell got the show of their lifetime .

My best moment exposing yet
