The fiery canine's noises get deeper, almost growling. Slightly wary, you stop rubbing, and the growls are replaced by a whimper. Not wanting to upset the dog, you keep rubbing him belly. Why was he liking this so much?

As his growls become louder, something pokes your arm. You glance at it, and reel back. The tip of the Arcanine's red penis is brushing your elbow, Its just the tip, but its already the size of your hand.

Thinking of the cock and your hand gave you an idea. A scientific one, ofcourse. There was no point estimating. You needed to do some measurements...

Walking round the sleeping behemoth, and carefully avoiding his tail, you stand between his back legs. You can see him in all his glory, and something stirs in your trousers. Just looking at his growing penis, his bulbous hanging balls and his tight anus turns you on like nothing you'd ever experienced.

You're alone, deep in the woods, miles from anyone, with a sexy Arcanine who is fast asleep. And you're both horny.

What the hell do you think is going to happen?
