The first thing you notice is a strong odor, coming from where the tiger's genitals must be. Shivering, you lift your hand to touch them. Not really knowing what you do, your hand starts moving up to the tail, stroking it gently. Then you hold off - you take a closer look and nod acknowledging - this must be a tigress! You can't see a member or whatsoever, and then there are two holes...
Again it must be some other person deciding, as you get up. You crotch is now at the same height as the tigress' vagina. You suddenly forget all your concerns, you now know that this is what you always wanted. You ignore the fact, that you are in a zoo, with people around, possibly coming around every second. You ignore that you are a human, and that humans normally don't mate with... animals. All that counts now is to make love with that gorgeous being.
In a hurry, you lower your pants, pull off your shorts. Your are now standing behind the female tiger, your penis totally erect. That odor escaping from her cunt bedazzles you, getting stronger with every second. You hear her purring...
Then you can't wait any longer. Panting in excitement and your heart beating fast you enter her body. Immediately, a wave of sensation lets your body stiffen. Your mind completely lost in another dimension, you feel your bodies unite for single moment, seeming to last forever. You keep thrusting in her for a long time, moving around while inside her. Surprised, you hear yourself growling like a wild animal, when you both come at the same time. After feeling your semen escaping your member and filling her, you lie down on the floor, satisfied, feeling her spirit floating through your own body.
