"Nikki, you're going to be my bitch poodle again. Now while you change, I've got to make a call," Brittney said, and picked up her pink cordless phone.
"Hello, Richard, can you come over now....Great, when you get here come around back and right up to my room. It's the third door on the right. See ya soon!" She laughed.
"Richard? Who is Richard? Not, Ricky. No, wait, that big hairy senior dude is called Richard. Is that who she called?" Nikki mutters deliriously, every other word is now a bark. He is feverish. Changing so many times in such a short time is taking its toll on Nick.
It is the senior dude! Nikki realizes as the hulking figure comes through Brittney's door. He is wearing a stained tank top, jeans and a black motorcycle jacket. He looks closer to 25, than to 17. Thick five o'clock shadow covers his chin. Brittney offers him a drink, and introduces Nikki to Richard.
"You know, I bet you would make a handsome poodle. Don't you think?"
"Nah," Richard already seems hairier, his brow lower, he is definitely changing, "I fancy myself more as a Mastiff, or Rottweiller, or maybe a Doberman!"
"No, I think you'd make a better poodle, Richard."
"Maybe Great Dane,rrrrr maybree a prit brull?"
Nikki realizes that she is in heat, and Richard's cock is now rock hard. He continues to change into a very large black dog.
Brittney is flustered, and injects Nikki, as half dog Richard prepares to mount Nikki, "Nikki, can't have mutts. You're already in heat, so I want you to become a champion version of whatever breed Richard ends up morphing into, okay? Nikki, you're becoming Richard's mate."
In his/her fevered state, Nikki thinks "Become Richard's Mate!"
Richard's knot slips into Nikki. Nikki begins to grow larger to complement the beast mounting her. Brittney removes Richard's remaining clothing.
