The Zoo/Rim him
From Create Your Own Story
< The Zoo
You lean down, nuzzling beneath Oscar's balls and running your tongue over his rosy hole. He squeaks in surprise, then moans as you begin to bathe his opening with slow, forceful strokes of your tongue. You grab a cheek in each hand and spread his ass wider, pushing your tongue inside him and stretching the muscles.
"Master, please," he gasps. "Master, please - fuck me." You can feel him trembling and when you raise your head, his cock has emerged from the sheath again and glistens in the faint light from the mouth of the cave.
