As Kevin was talking his nose blackened slightly and flooded in new scents. Lifting his nose he smelled something he had never smelled before and it was affecting him in a way he never imagined.
"Holy Shit!" He said as he closed his eyes and lifted his nose in the air to take a deeper sniff. "What's that smell?" with the deep breath he instantly felt a growing tightness start inside his shorts. "Oh no!" he said turning his back to Kimberly as the bulge got more pronounced and tight.
"What's wrong now Kevin?" Kimberly asked calmly.
"Nothing! Don't worry about it, just stay over there!" Kevin replied sounding in pain. It didn't take much longer for him to start unbuttoning his shorts to release the pressure in his tight underwear.
Kimberly just stared as he dropped his shorts giving her view of his hairy ass and 15 inch tail hanging down.
Kevin whined as he saw what was hiding in his shorts, his cock was huge now, and hard as a rock sticking strait out. A hairy fold of skin covered part of the member, pulled back due to its erection, but the skin didn't attach to his groin like a normal dogs does. His member dripped with juices, the smell of a female somewhere causing him to start to give into the urges.
His mind in chaos, it quickly decided how to react...
