You know this isn't right at all. You are a man, and a human. There is no way your going to submit to a dog. There was just no way. You move to start to run when you feel his paws pressing down on your back. You try to struggle as you feel him putting more weight down to hold you in place.
Just then you feel the tip of his cock forcing its way between your lower lips, into your hot sex. The pleasure in amazing, nothing like you ever felt. Your entire body ached for that cock as he began to slide in and out. Then you could feel the swell of his cock as his knot grow, pressing hard against your cunt, starting to slowly force its way in.
Part of you wishes to stay still, to accept that large knot but you know its so very wrong. You struggle as you try to pull away, but theres only seconds before the knot is within you, locking you to him. You know, if there is no escape if that happens...
