Emma probably starts by tenderly messing with Norman's hair, giving him a false sense of security that he knows deep inside won't last. He clenches his buttcheeks in anticipation before she even moves away to plant a kiss on his forehead that he knows exactly what it means. He sighs and unbuckles his belt, the rest of the clothing dropping down as he puts himself in the right position. Blindly, he can only know what's going on behind him as a buzz only slightly startles him and lets him know absolute destruction is coming soon. He winces and in one swift motion it is done. And for hours it goes and goes until she tires or he can stand no more, tears running down his face but regretting nothing. His ass is sore, he can't sit straight for weeks, but Emma promises she'll let him have a turn once he's feeling better, just as a treat. Humanity must prosper afterall and as fun as his butthole is, it won't lead to impregnation and she's still set on spreading the human race and overtaking demonkind, at the end of the day.
