Before Robbie could make a decision, he heard a car come up the driveway. His Mom had finally arrived and exited the car with a ton of different shopping bags. Robbie wondered if his mother knew he was now Maggie the dog. He wasn't sure if Patty had shared his transformation with her.
"Did you buy out the stores?", said Patty as she walked down to help her with the bags.
"Just some extra clothes to experiment with on our vacation.", said Mom with a smile. "I stopped at the thrift store to pick up some special items. Where are Robbie and Lilly?"
"Oh they're around somewhere. Come on inside. I have dinner ready.",
Said Patty.
The two entered the house as Robby realized him and Sammy were alone again.
After that little encounter, Robbie made up his mind, but wanted a little more privacy. It would be embarrassing if Patty or any of his family members saw what he was up to. He quickly licked Sammy's face and headed behind the house, where there was a little more privacy. As he looked back, he noticed that Sammy was right behind him, wagging his tail and panting happily.
"It's perfectly normal. After all, I am a bitch in heat. I don't think I could control my urges, even if I wanted to.", thought Robbie as his new hormones took over. After a brief examination of his surroundings, he was pretty sure that his activities wouldn't be interrupted. "Okay Sammy, come and get me!", thought Robbie as he presented his rear.
Sammy nipped Robbie on the flank and ran further away. Robbie realized that he wanted to play as he turned and waited for him to give chase.
"Playing hard to get!", thought Robbie as he pursued Sammy. He was going to have to work at it a bit. The two dogs played and wrestled for the next 20 minutes or so before they both collapsed on the porch, exhausted and panting heavily. After a moment of rest, Sammy made his move. Before Robby knew what was happening, Sammy mounted him and started pumping away. Robbie pushed back to meet his mate's thrust as a low whine escaped his snout.
It wasn't long before the first orgasm hit. His eyes rolled back in his head as the pleasant sensations washed over him. "Oooooooh yeah! That's it Sammy! Goooooood boy! Thought Robbie as another orgasm hit. It wasn't long before Sammy finished.
Robbie was finally coming back to his senses as he realized where he was. "Oh no! Somebody is going to see me for sure!", thought Robbie as he tried to free himself from his mate, unsuccessfully. The two were knotted together and he wasn't going anywhere just yet.
Robbie's head swung around as he heard a noise from behind.
