Deal with the devil 2

When they leave, I change into a bird, then take off.

“Whew, that was something.” I think. “I can’t wait to try some other animals.”

I fly down to the zoo, and only then do I realize a flaw to my plan. There are people at the zoo, so how am I going to have sex I decide that I don’t care, I need more sex, and I have a quick solution. I’ll be a fly, I’ll hide in some cranny in the pen, transform, then have some fun. I’m flying over the zoo when I see the first lucky animal, a wolf in the woodland exhibit. I change into a fly and drift down toward the caged play area. As soon as I land behind a rock I morph back into a human, then look around. The caged area seems smaller now than it had from the outside, but I suddenly realize a huge oversight on my part. I’m in a cage full of wolves! Suddenly I feel hot breath on the back of my neck, and there behind me is the biggest wolf I have ever seen. He lifts his upper lip, and shows me his huge canines, but doesn’t growl. That’s when, out of stupidity, I accidentally look him in the eye. The changes are immediate, coarse grey hair shoots down my body, my clothes disappear, a tail shoots out of my behind, and I feel my face extend out. My hands become paws, my ears migrate upward, and my hearing and sight sharpen significantly. Out of all of this one thing overwhelms me, I can smell everything. Things weeks old, seconds fresh, and foremost of all, wolf. Before I can do anything, the alpha wolf is on top of me, and I smile inwardly. This is what I came for isn’t it

The wolf is wildly humping at me, clawing my sides, and his thrusts force us out from behind the boulder. I hear immediate gasps as children and adults are suddenly aware of what is happening, and I laugh to myself at the faces of some of the parents. Some are horrified that their children are seeing this, others stare rudely, but I am suddenly interrupted from my thoughts when he finally hits his mark, sticking himself deep into me. He proceeds to pump fast and hard, faster than I had ever thought possible, his unbelievably heavy balls slapping me with each thrust. My cunt is being stretched to new limits, his ten inch dick far too big for my tiny wolf pussy, but strangely there isn’t any pain. My pussy just stretches further and further with each quick thrust, the pleasure spilling out of me. Both of us are panting hard, and it seems like we had been joined forever in ecstasy, when something new starts to happen. At first, I think that he’s trying to shove his balls up me with his dick, and I’m fairly certain he won’t be able too, but that can’t be. His balls are still hitting me. Then it occurs to me, it’s his knot. It doesn’t feel quite as big as I had expected a dog’s knot would be, it’s only about half an inch wider than his penis, but it still won’t fit. He begins thrusting harder and harder, slamming his knot into my loosening pussy, and I become aware that both his knot and his penis are slowly enlarging, expanding my cunt, but he only hits me harder and harder until, in just a few moments, he presses his knot all the way into me. Now I feel pain as my opening is stretched wide, and he locks into me like the ball joint in my car’s headlights. As he pops into me I feel the head of his dick slam into my cervix. His stroke is shortened considerably, but he keeps pumping, pulling at my vagina, then pressing his pointy dick into the hole of my taught cervix. As he keeps humping me, both of us joined together, I come to the realization that his knot and dick weren’t quite at full mast, but they are certainly heading there. His shaft is expanding steadily, and getting longer and thicker. His knot is also inflating, creating an airtight seal around out gentailia. His steadily lengthening dick is pressing deeper into my cervix, finally wedging it open and plowing into completely new areas inside of me. His knot had now become only slightly smaller than a soft ball, and every jerk of the wolfs body sends thrills of pain and pleasure down my body.

After only a few minutes of being tied, the wolf starts to move faster, then plants himself deep into me. His whole body contorts, and right on cue I start becoming inflated with cum. Not one drop makes it out of my tightly closed cervix and the pressure starts building from the incredible amount of steaming hot cum erupting from his penis. Even as it starts to hurt my belly, I climax and cramp down on his dick, milking him and encouraging him to continue his cum. When he’s finally done cumming the cum is under painful pressure, but before I can do anything he starts fucking me again, his dick pushing deep into my uterus full of cum making it stretch so badly I nearly think it ruptured. Cum starts to shoot out of where my cervix and his dick are joined, the strength my cervix muscles unable to hold back all of his cum, but his knot prevents any of it from escaping me. My vaginal muscles contract hard and sporadically, I can’t stand this kind of abuse to my pussy and I start to lose control at the prospect of him filling me like that again, but sensing my dissention the wolf nips me hard in the neck, letting me know that he’s in charge, and he wants me fucked. I whimper, the pain and pressure in my pussy bringing almost unwelcome amounts of new pleasure that I can’t release. It’s like my pussy is on clockwork, and can only cum after a certain time, not a certain amount of pleasure. It feels like his dick is growing even larger, and once again after several long minutes he tenses up again. I know what will happen, so I try and brace for it even though I have no hope. His dick pumps thick streams of cum into my uterus, which is already at maximum capacity, and the cum forces it’s way painfully past my cervix. He starts inflating my vagina, and my vagina soon swells to triple his original width and going.
