They trick the Doctor while making an important discovery.

To be honest, during the exams not much happened that was unexpected or noteworthy, except when Dr Hart asked Rose (me) to let him study her erection and ejaculation. We only accepted if no one else could see, so we did the test which consisted of me having an erection while devices monitored Rose's body, then cumming in relatively large containers, to measure the amount of sperm produced and examine it afterwards.

The cum collection was carried out with some wires and sensors placed on my body and dick, which from what was said would be to collect data to understand how Rose managed to have an erection with a dick that size without even feeling sick due to the lack of blood in the rest of her body.

After collecting the samples, we waited for approximately six hours for preliminary test results. We waited in a room reserved for us to occupy during this time. While we waited, we received a visit from Daisy, who was also curious to know the results.

Unlike her father, Daisy immediately realized that something was wrong with me and Rose and, after she insisted, we revealed about having switched bodies.

"Please don't tell anyone about this, at least not yet. We hope to find a way to undo the switch, and if we don't find one before the end of the summer holidays, we will reveal it ourselves." Rose said

"I can keep your secret this time, but I want you to promise me one thing in return. If you can figure out how you switched bodies and undo the swap, I want to know everything you discovered." Daisy said

"How about we change the subject. So Daisy, how do you feel about having a dick?" I said

"That's right, I'd also like to know how it's going for you. I think this might be my fault if you are having problems because of this." Rose said

"Don't bother with that. Of course, I still find it strange at times, as if it weren't real, and that I had to throw away all my panties because they no longer fit, but other than that I'm actually enjoying having a dick." Daisy said

"So you don't want to go back to normal?" Rose asked

"I have no interest in going back to being a simple dickless girl. My father has been researching to understand the issue and I know he wants to use this to get me back to my old self, but even if he finds out I will refuse treatment." Daisy said

"What about Rebecca? Is everything okay with her?" I asked

"With Rebecca, the situation at her house is a little complicated, at least in relation to her mother. Rebecca herself says that she loves having a dick and never wants to lose it, but her mother insists that she go for treatment to remove it. To increase the conflict at home, her father took her side saying that if she was happy like this then no one should interfere in her choice. The conflict escalated even more two days ago, as Rebecca's mother caught her fucking her sister. Rebecca's sister said that she was jealous and wanted to grow a dick too, and that she was hoping this condition was contagious." Daisy said

"If this is contagious I don't think you would need to have sex, because I never fucked any of you to make your dicks grow." Rose said

"And the same thing didn't happen to you as it did to Rose, did it? Have your dicks grown bigger since we found out about them?" I asked

"No, our dicks are still the same size, and unlike Rose, both Rebecca and I still have our vaginas." Daisy said

At this time, the bedroom door was opened by Dr Hart, whose gaze went straight to Daisy and he seemed to be angry.

"Daisy, I remember very well being told to use condoms if I was going to have sex, didn't I warn you?" Dr Hart said to his daughter

"I think you said something like that, but I ended up forgetting." Daisy said

"I realized this might be the case. I just received a call from her friend Rebecca's father and he informed me that they confirmed that she is pregnant. Judging by the events of the last few weeks, I think I can say that you are the father of the child." Dr Hart said

"Me being a father? No, I'm a girl and there's no way I can be a father." Daisy said

"Girls don't normally grow dicks and not only do you have one now, you're perfectly male fertile. Now you will have to take responsibility for what you did and assume paternity of the child." Dr Hart said

"You are right. I don't know if I'm ready to be a father, but I will do my best to raise the child." Daisy said

"That may not be all. I believe you let her fuck you too. How is your menstrual cycle?" Dr Hart said

Daisy froze and said "My period is late."

"That's what I feared. Come with me immediately." Dr Hart said and left the room taking Daisy with him.

Later, Daisy came back and said that she was pregnant too. She and Rebecca had gotten too excited with their new dicks and ended up getting each other pregnant.

Shortly afterwards, Dr Hart reported to us the results of the first tests, saying that they found nothing that could indicate what caused Rose's change, no virus or unknown substance in her blood, but they would continue to do more detailed tests, which could take weeks to have the results, to try to see if they still discovered anything. He also noticed that in Rose's erections, what made the dick hard was not blood, but probably cum generated at the time by her balls, which were eliminated from her body along with the orgasm, and this would explain why her erections not going away once they formed and the dick becoming flaccid so quickly after cumming.

After receiving this information, Rose and I returned to our house, where we researched body swapping on the internet in the hope of understanding and correcting our situation.
