He does

The last traces of resistance Andrew had disappeared when Vanessa kissed him, and just like she said, he started hearing a voice inside his head. At first it was distant and unrecognizable, but as he closed his eyes trying to focus on the voice and it became louder and more clear with each second. "INFECT! SPREAD! FUCK!"

As soon as he heard His voice, he opened his eyes and saw the entire world in a new light. All the time he spent trying to suck up to his superiors for promotions felt like such a waste now, if he wanted something he should just take it and he knew exactly where to start. With a growl, he grabbed Vanessa and pushed her towards one of the beds in the ER room.

Vanessa couldn't contain her excitement when she saw her formerly professional and serious resident transformed into a sex-hungry stud. Lying down on the ER bed, she pulled her skirt up and slid her now ill-fitting panties to the side, showing him her wet rejuvenated pussy. "Well?~ What are you waiting for, Andrew? Can't you see your attending physician needs you?" she said with a sultry smile.

"YOU SLUT!" Andrew screamed, as he thrust his cock inside her pussy. He had never felt so much pleasure before; he used to respect and admire Vanessa as a mentor but now he only saw her as a sex toy to sate his lust. After a few thrusts, he finally came inside her, triggering the virus' final changes in his body. Andrew felt Vanessa's pussy become tighter as his cock expanded until it was 12" and as thick as a beer can, his balls also swelled to the size of baseballs and they were being filled with infected cum, his entire body and muscles grow until he ended up looking like 6'8 Adonis.

"FUCK! You got so big! So perfect for my slutty pussy!" Vanessa moaned, as she was being stuffed by Andrew's enhanced cock. Thanks to the virus, her insides had mutated to be able to handle even even the biggest cocks, however she could still feel a slight sensation of pain that only made the pleasure much more intense.

After basking in the sensation of his transformation for a moment, Andrew grabbed Vanessa's hips and started fucking her even harder than before. He was so focused on the sexy doctor, he didn't notice Alex and the female patient approaching them.
