The hard prod pushed John forward a little, but the tiger's forelegs shifted to hold him in place. The male's odor was hot and rich in his nostrils, and he tried to shift down a little to help the male find entry. Instead, the animal squatted, first sliding its hard, rough penis between his legs, then pulling back and thrusting against the crack of his buttocks. John gasped as the stiff organ penetrated his flesh, painfully at first, but then with a throbbing pleasure as his flesh remolded itself around the tiger's member.
A large, coarse tongue began to lick the back of John's head, dulling his senses to everything but the new sensations increasing with each thrust, the tiger pushing deeper each time. John's wild boy look was altering, his head changing shape and orange and black fur spreading over his body. His hands thickened, fingers drawing in and sprouting thick black claws, and his penis drew in along with his testicles, teats forming along his... now her, underbelly. The tiger's jaws opened wide to close a0round the back of her neck, and he held her in place as he continued to mate. The sensation became painful as the animal's barbed cock scraped at her tender flesh, but instinct and the pressure of the male's teeth kept her still.
When the huge tiger finally shot his seed into her, John joined him a roar. Even though the mounting had hurt, it had also filled a new need, a base instinct to reproduce that was part of the tiger mindset. The two remained coupled for a minute or two more, then the male withdrew and shook himself, laying down tor est. John felt dazed and confused, but also very pleased. It would take a day or two before it was finalized, but she was sure she would be pregnant with multiple cubs. This pleased her much more than it should, and part of John's mind was worried about the passage of time. They were only here for two weeks, but she would just be starting with her pregnancy.
It was hard to stay focused, though. For now, she flopped down by the male and panted, her hindquarters still sore. There was no question in her mind about carrying the cubs - she just didn't know how it would affect their vacation.
