The fox, with his pert, pink nose and bright, eager eyes, nuzzles the wolf's neck, inhaling his wild, primal scent. The wolf, his fur as dark as night, responds by pinning the fox down, his powerful paws holding the smaller creature in place. The fox's tail wags in anticipation as the wolf's massive, veiny cock presses against his entrance, stretching him wide. The wolf pushes in, inch by inch, filling the fox completely, his thrusts deep and deliberate. The fox yips in pleasure, his own cock leaking pre-cum as the wolf's knot begins to swell, locking them together in a furious, unending rhythm, their bodies coated in a sheen of sweat and saliva, their fur matted and sticky from their intense, explicit union.
