After working out in the gym for a hour and a half, i had a load of butt butter.

You know Lizzy? She made me cum in her ass, and then she sucked me off with butter in her mouth. I came so hard! That butt butter was so good!

After anal sex, and not a quickie either, you splooge inside a chicks ass and when you pull out, brown coloured cum oozes out is your butt butter. Not to be considered in the pornstar biz (as they are clean hooped normally) but usually amateurs with unwiped/non-enima cleaned poopshoots.

I'm not going in there until you scrape that butt butter off.

Yo check out this Butt butter on my toilet paper.

the butt butter in my ass had been forming all day, making me feel and smell like a dirty hog

Skinner doesn't know how to wipe his ass, so he's always producing fresh butt butter.
