Prove it.

The bovine, surprisingly, sticks his ass out from the stool, you just now noticing his bare, sweaty ass has been sitting on the stool the entire time. He glances downwards, and then back at you, a clear suggestion if you want his seal of approval. His tail lifted and his nuts hanging just off the edge, slopping out due to the sweat as he stuck his ass out. The huge barbarian grunts once more, looking down at you. His face still ambivalent.

"Prove."

You shiver, his surprisingly pointed wording leaving you filled some kind of way, your eyes trailing down to the saggy, sweating nuts, and his puckering asshole. The wink it gives you perfectly timed to your viewing of it. The haze of musk filling your nose as you bring your face just a bit closer, as if to get a better look to make your decision.

Question is, are you really going to get down on your knees and do it in front of all of the people in the building? You're already building up an audience. There's no way for this to be discreet.
