Cole was interrupted by another wave of spasms that shook his body, shortly before Sam started trembling and arching her back as well. They both let out a canine whimper before their bodies began to change again, the tail and ears shrinking back, paws reverting to feet and hands again. The fur on their body crept away, leaving only a patch between their legs.
A warm tingle moved down their spines and built in their groin, and their clits exploded forward in a one inch protuberance. Their full breasts remained the same.
"Cole... look... I think you spoke too soon..." Sam grimaced at the sign of her manhood returning.
"Why is it stopping now? I mean, I'm sorry this is happening to you, but I want to be fully male again." Cole said in frustration.
"Maybe it's because of them..." They both looked at their progeny, which was also squirming and changing in front of their eyes, becoming more canine-like by the minute until they looked like plain puppies, still suckling on them hungrily.
Cole wasn't sure what to do anymore.
"Sam, listen. I need to get back home before my family starts wondering what's going on, and I can't attract attention. Can you keep our puppies hidden here at your place?"
"Uh, I don't know how I'll hide puppies at home but my family won't be home until late, so I can try, I guess..." Sam hesitated.
"I don't want to ditch you like this, it's just my sister has been acting weird since the thing with Erika, if I can avoit it getting any weirder it would help to keep the secret."
Sam seemed to ponder for a moment before nodding. "I understand."
Cole awkwardly picked his son pup and placed him against one of Sam's free breasts, where he resumed suckling. He wiped his own body from the fluids and put his clothes back, his teats and breasts giving a funny shape to the front of his shirt. At least his dick was slowly growing back...
"Sam, I don't know if I can stand up to Erika, but I'll do anything to protect our puppies," he said before turning away, walking out.
