Lube it!

The Minotaur tears off the chains and yanks him onto his knees before gripping Guin's head roughly as he tosses the loincloth to the side and began to prod it's giant member against the leopard's face. Guin groaned in disgust before the minotaur shoves the giant shaft into his mouth, Guin let out a gagged yell as the beast began to pushed another inch in. Pretty soon the bull was maintaining a slow and steady rhythm as he pushed into Guin's throat, the leopard weakened by the minotaur's intense pheromones.
