Switch Gender Virus

Oliver was dreading that moment, but it arrived. He just received a text from his girlfriend Julie.
Since he caught the Switch Gender Virus, he and Julie knew that she was also gonna catch it. The virus was highly contagious. It worked fast and relentlessly. In six hours the gender change was complete. That's what happened to Oliver. One day he felt sick while at work and six hours later he had a pussy and double D breasts.
After that Julie lived for almost two months waiting in anxiety for the day when she also was going to change. It happened one morning just before she was going to work and Julie immediately knew it. She felt a sudden fatigue and itchness throughout the body. Julie managed undress (she was going to sweat a lot, not to mention growing) and layed in bed waiting for the inevitable.
Midway through the changes, she managed to text Oliver, to inform of what was happening. He rushed in as soon as he could, which meant at the end of his day job.
As he entered Julie's room he saw her for the first time, nude. She was tall and still blonde. But it wasn't what caught mostly Oliver's attention. It was her dick. Julie grew an obscenely big dick.
Oliver knelt and grabbed Julie's cock and exclaimed: "It's huge!".
Julie just looked at him embarassed, as the touching and the view of Oliver's cleavage made her cock to harden.
Oliver on the other hand was feeling extremely warm between his legs. He was more and more horny since he became a woman, but that was the first time that he understood what was he horny for.
They surely were going to enjoy their new bodies...
