Fingering my butt in a public bathroom

I know it's soooooo wrong but I like to strip down to my underwear, pull them back and stick my left middle finger in my unwiped doodoo butt in a public bathroom. I've done it in private ones with the door locked too. I dig so deep my middle finger is pounding my gspot really good and I moan like crazy like it's nobodies business. The thrill and suspense of getting caught is soooooo exciting. I even went to a CVS bathroom at 4 in the morning, went in the bathroom, locked the door and went to town and came like it was nothing, the staff didn't care they let me finish

But is it wrong to do that though getting caught with my left middle finger deep up my unwiped butt I think would be a VERY vulnerable position. One time a security guard walked in on me doing it to myself and I finished, the amount of thrill and satisfaction was insane. It just feels fitting to finger myself in a public bathroom, nasty to the greatest degree
