Jim leapt through the air and landed on the deer's back with a roar.
The panicked animal tried desperately to run away, but Jim grabbed its legs with his dexterous feet and they toppled to the ground together, the deer struggling to escape from Jim's iron grip.
Jim grinned evilly as his thick tongue snaked out and wrapped around the deer's neck, tasting the thick creamy fur and leaving it thick with saliva. The deer had stopped struggling now, but Jim could feel its hear racing beneath him. It turned him on. He felt a stirring in his groin and without looking he could tell that his thick cock was pushing its way out of its sheath.
One thought permeated his mind, to fuck, penetrate and corrupt. With a smile Jim let his tongue roll over the deer's face, darting quickly into the deers mouth for a split second before sliding slowly back into his mouth.
The deer was exhausted now and seemed resigned to its fate as Jim repositioned himself, lining up his thick cock with the deers ass.
It was now that Jim got a good look at his fully extended member. It was hugely thick jutted nearly two full feet from his groin. Its entire length was covered in dark veins that pulsed slowly, pumping some vile liquid though the pitch black organ. It glistened slightly in the light with the moisture from his sheath, a thick black liquid that almost dripped off the penis before being absorbed back into Jim's body in the form of a wispy tentacle.
Jim lined up his huge member with the deer's ass and thrust roughly into the animal, giving a deep hissing sigh as the pleasure washed over him. The deer, startled by the sudden penetration, summoned the last of its strength for one last attempt at escape,but Jim's strong arms held the deer steady as he mounted it. His toe-claws dug deep furrows in the ground and he began to thrust in and out of the beast. He could feel every ridge, each vein and every heartbeat. His cock was so sensitive.
“Yeeeeeeeeesss....” Jim cried as he pumped. The deers frightened attempt at escape only serving to pleasure him further. “It feels WONDERFUL.”
Suddenly Jim's eyes snapped wide open and he felt himself tense up. His cock throbbed with need and he felt his balls tighten as he began to cum. He could feel each drop of thick black semen as it pushed up through his huge rod and out into the deer. He had never experienced anything like it. It was like someone was massaging his cock from the inside as well as the outside. He found himself unable and unwilling to suppress an roar of pleasure.
The cum seemed to flow endlessly from his cock as he orgasmed again and again, pumping his seed into the deer at a tremendous rate.
Slowly Jim became aware of a strange sensation. It seemed as though he could still feel the cum after it had left his body, flowing through the deer. It felt as though he were reaching inside the deer, filling its veins with his own body. Slowly taking over. Jim grinned even more wildly as it dawned on him what was happening. He was corrupting the deer, taking it over, becoming one with it, absorbing its life essence into his own. Becoming something else. Something new. Something he'd never imagined.
