Can you explain to us why dogs lick each other's butts? It's really weird and gross. It just doesn't make sense to me. I mean who would actually want to, like, lick that nasty mess?” “Ahh, well. yes. You're quite right. It is dirty. You see, the chemicals tell dogs a lot about each other.

She rubs the ass-fingers on the underside of her nose, wipes them on her lips, and then gobbles them up. Her Hairy Girls Fucking pussy is screaming. The right hand then dives down onto her clit, furiously rubbing. So, as I hinted, I occasionally like to take that power away from him. Trevor gave Mitch a startled look. I started to unbutton them, and said Squatting on the wrong side of the ropes at the edge of the ring, she presented her labia and anus to the gathered audience there nicely.
