When I was about to get home Martha had another erection. Gloria said that her dick was hard too and that she wanted to try something, so she asked her friend if she was up for a quickie together before they said goodbye.
When they arrived at the house, the two went to the bathroom, where it would be easier to clean up later. Gloria wanted to know what it would be like to be fucked by Martha with her new dick size, enjoying it while she still had a vagina herself. This was a challenge, as Martha's cock was now so thick that it was at the limit of what Gloria could handle, and so long that she was unable to penetrate fully. She came once more inside her friend, who still wasn't satisfied and penetrated her ass with her new cock right after.
Martha said she didn't like anal much, but Gloria said "It's no use complaining. You've fucked me over so many times and now that I have the tool it's time for you to pay me back. Since you don't have your pussy anymore I have to settle for fucking your ass." In this they continued until they reached another orgasm.
Shortly after Gloria said goodbye and left for her house and Martha took her cell phone to see a message she had received from her mother, who asked if she wasn't going to pick up her son. With everything that happened she had forgotten the time and it was later than she thought, so she took her own car and went to her mother's house to get Peter.
When Martha arrived at her mother's house, Rebecca immediately noticed the bulge in her daughter's clothes, who found herself with no choice and told her mother all about the experiment. Rebecca disapproved of what her daughter had done, mainly because it would make it difficult for her to care for her child. Because of this, the school principal did not let Martha take the child, saying that she would take care of her grandson until the experiment was completed and they had turned her back into a normal woman.
Peter was informed that he was going to spend a few weeks living with his grandmother so that his mother could travel to do a job. He cried a little, saying he didn't want to be away from his mother. When Martha promised that she would call him every day he calmed down, kissed her on the cheek and said he would be strong and wait for her to come back for him.
During the following days, Martha saw that her mother's attitude had been right, as her libido was very high and erections were very frequent, making her have to masturbate several times a day. It would be a problem these situations with Peter around, and to make matters worse a faint smell of cum filled the house and she couldn't get rid of it. Aside from this setback, she realized that she was stronger than before, as she was opening vials more easily than she could before, and other jobs that required some strength had become much easier for her. In her time alone, she decided that she would continue with the experiment, because if it was to give her son a better future, any sacrifice would be worth it, so she called the laboratory informing her of the decision and confirming her presence for the next test session.
When the day of the next test session finally arrived, Martha woke up to her cell phone ringing. She answered Gloria, who apparently was very happy about something.
"I had been wondering for days that my period was late, but I thought it could be the effect of the experiment and the fact that I had a dick now that had affected this, but yesterday I woke up nauseous and thought about the possibility of being pregnant. I did the pregnancy test at the pharmacy and the result was positive, but even so I did the blood test and it confirmed it. I know it sounds weird to say this to a woman but I'm pregnant Martha and you are the father of the child." Gloria said
Martha was shocked by the news, and deep down she felt divided, because she never expected to have more children, giving Peter a brother or sister, and she was happy with the news, but at the same time she couldn't let go. to be surprised by the fact that she would be a father.
They ended the call and Martha got ready as quickly as possible, got in her car and drove straight to the lab, where she hoped to meet Gloria and talk more about her pregnancy.
