quick munch on buddy's butt

The first time I licked a guy's ass I didn't even know it was a thing. I didn't even know there was a name for it. I just knew it must be something very bad to do even though I loved the way it smelled and tasted and the way he reacted. He'd never had his ass eaten before either but once I did it to him he couldn't get enough of it. Carl had kind of big balls, his sack wasn't big going from side to side and his balls were kinda average sized but his sack hung real low. It hung way down below his cock and man oh man he loved getting his nuts licked and sucked on. Sometimes I think he liked me sucking his balls more than his cock. One of his favorite positions was for me to lay on the floor and he'd kneel over me and drop his sack in my mouth. I'd lick tease and suck on his balls for 20 minutes. One day I was licking away when he got a cramp in his leg and just like that his ass was on my face and my tongue was lapping at his tight pucker. I kinda screamed and tried to push him away with my lips because my arms were trapped under his legs. Between the cramp in his leg and my tongue on his asshole he didn't know which way to go. I was trying to get out from under him and all of a sudden he was sitting right down my face grinding his sweaty ass crack against my lips and begging me to lick his hole. I think I liked licking his asshole more than he did. I never told him but sometimes it would be a little dirty and I'd lick it anyway. I felt kinda disgusted with myself for doing that but I don't know, I kinda couldn't help it?
