Adaptation time

Unsurprisingly, Sasha's parents were shocked by her new size when they came home a few hours later. A doctor was called for home care because there were no more clothes that fit her. The doctor was surprised by the growth, then revealed that the futa virus was undergoing many mutations, thus generating several variants from which their differences appeared from the 2nd phase onwards (dick getting bigger, becoming that of an animal or multiplying, among others... and some effects on the rest of the body, but someone becoming giant, Sarah was the first case registered). He also mentioned the unexpected situation of Sasha not even having an erection while he was there, as women affected by the virus, especially from the second phase onwards, were practically sexually insatiable. Sasha told him that she felt satisfied after being fucked by you and was feeling technically normal at the moment. The Doctor said that no one had thought of doing that, because women focused so much on their new dick that, when they had sex, they were the ones fucking.

After Sasha's home care, you also left for your house. The next morning you received a new message from Sasha calling you, because during your absence she had an erection again and it didn't go away even after she had cum several times, and she wanted you to fuck her again. So you went to her house and did what she wanted, this time with her parents at home, being able to hear all of their daughter's moans. Just like the day before, after you came inside Sasha's pussy, her erection fell fade away after her first orgasm. You reported this to the doctor.

In the days that followed, new clothes that were ordered for Sasha were ready and she was finally able to leave her house again. With what you observed and, studies with some volunteers that ended up being triggered after your reports to the doctor, the injection of male semen into a futafied woman put their sexual impulses temporarily under control, varying the time depending on where the exposure was , ranging from two hours, if ingested orally, until 8 hours after vaginal reception. You realized this by seeing that with every erection Sasha had, it was only calmed down after you came inside her.

In the following weeks, more in-depth studies revealed that male semen was the "medicine" to overcome all the sexual urges of futafied women, but only male semen, that of other futas did not have any inhibitory effect, quite the opposite, in addition to not reducing the desire, sexual relations had a very high chance of getting the other pregnant, so much so that there were pairs in the experiments in which both ended up pregnant. Treatment with male semen only had the effect of controlling sexual impulses, but it could not stop or reverse the progress of the condition.

Not knowing how things would go, you and Sarah quickly prepared the wedding, as she wanted the ceremony to take place before she reached the third phase of the disease.
