Only for scientific purposes, you understand

Ruby bit down on her thumbnail. Okay. she rationalised. Okay. So, the virus has two affects. The first is the lowering of inhibitions.

She looked down at her cleavage, barely concealed by the opaque white plastic.

Fair enough. But now that I'm aware of it, I should be in control of it. Okay. So the second impact, the situational awareness, means that I'm seemingly invisible to the others. I wonder to what extent this remains true?

Although she believed herself to be fully in control of her inhibitions, the thought of getting dressed again didn't enter her mind as she approached James. She hesitated, unsure what to do. Then she flicked him on the ear. He looked up, and for a moment Ruby felt her heart leap into her mouth. Then he shrugged, and returned to his work. This time she shoved him. He stumbled, corrected his balance, mumbled something under his breath and then returned to work as though nothing had happened.

"HELLO!!" Ruby yelled directly into his ear. "ARSE COCK!"

No response.

Physical and vocal extremes seemed to have no effect on his awareness, so Ruby decided to take a different approach. Returning to her own workstation, she grabbed a blank piece of paper and wrote "James, I am invisible; can you see me?" She then held it directly in front of his face.

Much to her surprise, James took the offending piece of paper off of her. He looked around, unsure as to where it came from, and then attempted to read it. Ruby watched in fascination as his eyes focused and unfocused. He began to blink, and squint, and turn his face away from the paper. After a few moments of this he crushed it into a ball and threw it away before returning to his work without a second glance.

So... **** physical and vocal stimuli are ineffective. External influences are also affected. She bit her lip and tried to think of another way. Suddenly, the thought struck her. Primal influence! Yes, of course. It was a virus, after all, and viruses sought to do what all lifeforms do; survive and procreate. On a primal level it would want to enter her body and infect her too. So, she had to do something to provoke a primal, sexual response from James to get his attention.

This is for science. she told herself as she stood opposite him, cupped her breasts in her hands and began to juggle them up and down. "Look at these, you sexy stud." she yelled.

There was no response. As she looked around, she realised that nobody was looking at her. Perhaps she needed to push this further. Gripping the narrow band of elastic under her breasts, she lifted this out and up so that her bare flesh was on display. She felt like a Mardi Gras flasher. Scientists, she rationalised, should be more dignified than that, so she lifted the top up and over her head, removing it completely.

She stood with her D-cup breasts proudly on display, her large nipples stiffening under the cool air, and waited for a response. None was forthcoming. But of course, she thought The mammeries are linked more closely with child rearing and motherhood. While it is certainly erotic, it is not strictly speaking the main sexual organ. A reaction is, therefore, unlikely.

Ruby decided that revealing her primary sexual organ, then, would be the most effective way of gaining his attention. She slipped her thumbs into the waistband of her panties and quickly yanked them down. She stepped out of them and discarded them on the floor along with her bra. A neat triangle of fiery pubic hair was now the only thing covering her modesty.

"Hello James!" she yelled. "I am naked and aroused and ready for sexual activity!"

Even as she said that, she realised it was true. If James did suddenly acknowledge her presence, and he did desire sex... well, she didn't know if she'd be able to stop herself.

But he didn't. As before he didn't acknowledge her presence. Which left Ruby naked, horny and frustrated. She found herself blushing as a thought came to her. She couldn't...
