Tom was curious to know how Sarah would grow a dick because she wants it. This came one night, right after they had sex.

"Tom, I need to talk about a very serious matter with you." Sarah said

"Serious matter? And what would it be?" Tom asked

"What would you do if I grew a dick between my legs? Would you still love me?" Sarah asked

"Of course I would still love you. Why such a question?" Tom said

"It's because I learned about a treatment using a cocktail of medications that can make a woman grow a fully functional penis and I'm interested in doing it." Sarah said

"And why do you want that?" Tom asked

"It's because I'm wanting to have new experiences and I believe that having a dick would be essential for that." Sarah said

"If that's why, then you can go ahead with the treatment. I will love you the same way, even if you are a hermaphrodite." Tom said

"You didn't understand me right. I said that the treatment will give me a fully functional penis, therefore testicles will also grow and I will no longer have my vagina after the procedure, I will be a shemale. The only way you'll fuck me will be anal. The process is irreversible, so once done there is no going back." Sarah said

This took Tom by surprise. He knew he had wished her to want a dick, but he didn't think about the possibility of her losing her pussy in the process. As it was part of what he wanted, he decided to just accept it, so anything he could wish for an alternative to reverse the process, or that the treatment had never been carried out.

"If it's what you really want, then go for it. I love you and not your pussy. I admit I'm going to miss this, but if it's what it takes for you to be happy, it's worth the sacrifice." Tom said

"Thank you very much. I will call the doctor tomorrow to schedule the start of treatment." Sarah said happily and kissed Tom

The next day Sarah looked for the doctor and Tom accompanied her to the office. The doctor repeated to them the information that Sarah mentioned the night before, going into more details and making recommendations. He said that Sarah should follow the treatment strictly to achieve the desired result, as her penis, testicles and prostate will be fully formed in 15 days and then only grow, and just 30 days after the start of treatment the Her dick will have reached the desired size. The Dr also recommended that the new member be stimulated as much as possible, including sexually from when she has her first erection, to help her body get used to the change.

When they got home, Tom and Sarah had sex, with her warning him that he should say goodbye to her pussy, as this could be the last time. Only later did she start taking the medicine from the cocktail she received.

After one day the visible effect was a minimal increase in the size of Sarah's clit, the next day the clit was one inch, growing until the fourth day until it stopped at 3 inches. Until then, Tom didn't feel any difference when he fucked her pussy. Although penetration was still possible, Sarah had been saying that she had been feeling less and less pleasure from vaginal stimulation, which at this point she no longer felt it at all, no different from him fucking her hand.

From the fifth day of treatment onwards, her vagina began to become not only tighter, but visibly smaller with each passing day, disappearing completely on the ninth day. In the meantime, skin advanced over Sarah's enlarged clit, which also became thicker.

This was the part where Sarah dedicated herself to learning to enjoy what she used to complain about when they tried it, anal sex. With her dick still incapable and her vagina already unusable, Sarah frequently asked Tom to fuck her ass. She noticed that although the first time was very similar to what she remembered and didn't like, each time the sensation was different and she liked it more, which she and Tom believed was due to her developing a prostate.

On the tenth day, Sarah already had her dick perfectly formed, but still not fully functional, as her sack was still empty and she was unable to have erections.

On the eleventh day there was no apparent change, but Sarah felt very sick, a side effect that the Doctor had said could occur, but that it would have to stop soon.

On the twelfth day, at the beginning of the day, Sarah said that she no longer felt sick, but she felt strong pressure in her belly, until shortly after lunch she felt the pressure move downwards, taking off her panties and lifting her skirt. she was wearing at the time, so she and Tom witnessed the time when her new testicles descended one after the other into her sack.

For two days, Sarah's new penis had apparently completed its formation, but Sarah still had no erections, mentioning only that she had a strange feeling in her head. Other than that nothing happened until the fifteenth night, when Tom and Sarah enjoyed the last moments before retiring to bed watching TV. Sarah, at one point, looked at Tom's face with a smile on her face, taking his hand and taking it between her legs, where he felt that her member was hard.

"So your dick finally got hard?" Tom said

"Yes, my first erection. I couldn't wait for it to happen. Can I try?" Sarah said

"Go ahead. Since you have the equipment, you can now use everything it is capable of." Tom said

Sarah gave Tom a kiss and stood up, quickly taking off her skirt and panties, showing off her hard 4 inch cock. Sitting back down next to her husband, she jerked off.

While watching his wife jerk off, Tom enjoyed the scene and ended up getting an erection too, touching himself slowly during it. His dick wasn't small, it was 7 inches and he knew Sarah liked that about him. Tom continued watching this even when Sarah came for the first time like a man.

After cumming, Sarah cleaned the last traces of cum from her dick and licked her fingers, then "The taste is different from yours." there looking at Tom, only then realizing that he was stroking his dick through his pants. "Oops, what am I seeing. Did you really get hard from watching your wife stroke her own dick?" she said with a big smile on her face and a teasing tone in her voice. Even though she had just cum, her dick was still hard and ready for another. Despite being a man between her legs now, Sarah was still a woman and her refractory period was that of a woman, allowing her dick to remain hard after an orgasm and her to cum several times in a row.

"You're really hot, even with a dick hanging between your legs." Tom said

"Do you really like it? So let's go." Sarah said and then ordered Tom to take off his clothes, also removing what was left of hers

With both naked, under Sarah's command, Tom lay down. She climbed on top of him and bent down, positioning herself to suck his dick while leaving her hard dick in front of his face, wanting him to suck her. He didn't want to disappoint so Tom took Sarah's dick in his mouth and started sucking. She moaned at the sensation and then responded by starting to suck his dick.

Tom was enjoying having his wife's cock in his mouth, seeing her small ballsack right in front of his eyes, while he had his hands holding her buttocks and had a view of Sarah's rear entrance. He was enjoying so much the moment and the view that he didn't notice when her orgasm approached and he received her cum directly into his mouth, surprising himself for having enjoyed the experience and the taste.

Finishing, now sweaty, Tom and Sarah took a shower together, where Sarah jerked off once again, and then went to bed to sleep.

Pensive in bed, Tom remembered that according to the Doctor, her dick was already formed, but would still grow until it reached its final size. He pondered how big Sarah's dick was going to get.
