Katy, reluctantly, took the dildo out of her pussy. She began to feel a void there and wanted to put it in again. But she didn't have the heart to say this to Clara.
"You will pay the price for using my things without permission." Clara said "get on all fours now." she ordered
Kat obeyed, then, curiously wondering what Clara had in mind she asked "What are you going to do with me?"
"Do you want to know? Then I'll tell you a little secret. This dildo you were using was just a replica. Now you will get a taste of the real thing." Clara said
"Like? We have no dogs!" Kat asked
"But we do not need one." Clara said looking at Kat with an erotic smile on her face.
Kat tried to say something but was speechless when she saw that something was lifting Clara's skirt. So Clara undressed, exposing her slender body, a body to envy any girl. The only thing that seemed totally out of place was the completely erect dog cock and the ballsack between her legs.
Kat, even surprised, also got more aroused.
"Now, no more wasting time, get ready, now I'll fuck you like the bitch you are." Clara said positioning herself behind Kat and penetrating her pussy. "You are too tight." she said
"Oh Clara, yours is so much better than that imitation. Go, fill me with your seed." Kat said
Shortly after Clara announced that she was coming and Kat said she was coming too. They both came at the same time.
Shortly after, at the end of the orgasm, Kat tried to get up but failed, because Clara's cock was trapped inside her.
"It's useless, we'll be knoted for a while." Clara said

Some time later, already separated Kat pulled the subject asking "Clara, I know I was wrong and shouldn't have used your secret toys, but I thought we were friends and there was no secret between us."
"I wanted to tell you, but I was unsure of your reaction." Clara said
"We're best friends, our friendship wouldn't end just because you were born with a dog's cock." Kat said
"I know. But, I wasn't born with this dick, I actually bought it almost two years ago." Clara said
"You bought? But since when can anyone buy a dick?" Kat asked
"I also thought that was impossible at the time. But one day I found a different store while traveling, it had many different items and I ended up buying that dildo ..." Clara pointed to the dildo Kat had found and was using before "....It wasn't white when I bought it, but after I used it that night, right after I came, this cock grew in front of my vagina and the dildo changed color. I had been surprised and searched the store again to find out what had happened. The store owner explained to me that this store sold magic items and that what I had bought before was meant to grow this dick. As I had liked to have a stick, instead of asking him for a way back to normal I bought the collar, which had the complementary effect to the dildo and made my testicles grow." Clara finished telling her how she had changed.
"But, do you still have your vagina?" Kat asked
"Yes, I still have." Clara said lifting her balls to show her pussy "I may have liked the idea of having a stick, but I still wanted to keep my womanhood."
"This is amazing. Where is this store? I want to go there too." Kat said
"Unfortunately she is too far from here. But you need not worry. I was already planning to take you there during our summer vacation trips." Clara said
"Great, now I'm more looking forward to the trip than before." Kat said
Two weeks have passed. They are already traveling around the country and arriving at the store that Clara mentioned. What do they do in the store?
