Maybe it was staying in the sun too long, maybe it was because you've been horny all day, whatever the case was, you are now balls deep in the ass of an equally horny tiger.
You didn't ever realize that you climbed the eleven foot tall fence, or got the pounce on a live tiger - a very impressive feat for anyone - and you really should have, but somehow didn't even notice that you were fucking him until he reacted to your hard cock buried in his ass. Now that he has noticed you, you're a bit screwed.
Whatever you were thinking of as you hopped into the tiger hibitat you're in for a lot of hurt becuase of it now.
You're not sure if things are going to get better or worse when you realize...
