Explore the base.

The more David moved through the vents, the more natural and easier moving in his new form became. As he passed an opening in the vent, he felt something new and stopped. A pull. Something was pulling him into the opening. It wasn't very strong at all and he could easily ignore it if he chose, but it was definitely noticeable. Almost like the pull of a magnet. This new feeling made him curious. What was on the other side? Because of this, David decided to investigate.

Arriving on the other side, he noticed he was in an office room. There was a door to his left and a desk to his right with all sorts of papers on it. The most interesting part about the room however was the person behind the desk.

David immediately noticed 3 things about the person. First, it was a woman. Second, she was definitely the source of the pull. Finally, and most importantly to his 18-year old mind, she was one of the most beautiful women he had ever seen.

Shoulder length blonde hair. Emerald green eyes. Perfect hourglass figure. Long, smooth legs that end in small feet with pink nail polish on them. Luscious, pink lips. Small, dainty hands with blue, manicured nails. Large breasts that looked to be at least a C cup. Her body was accentuated by her clothes, which consisted of a green blouse, a black dress skirt, and high heeled sandals.

The more David looked at her, the less he wanted to stop. She was drop dead gorgeous, and he would definitely be hard right now if he had anything that could get hard. Instead, his lust manifested in a new feeling. Or rather, the strengthening of an old one. The pull he felt drastically increased in strength, and he felt it growing the more he looked at her.

As he moved over to her, the pull continued to strengthen. By the time he reached the desk, he could tell that the pull was centered on her vagina. This realization caused him to pause, and he would have blushed if he had face. He was always kind of a loser in high school, so he had never so much as kissed a girl, yet here he was being drawn to the pussy of a woman who could easily compete with porn stars in terms of looks.

By this point, he had reached her feet. The pull was extremely strong now, but he was concerned about going any further. There's no way he could crawl up someone's leg without being noticed, right? He carefully stretched a part of him to touch her feet. Not seeing a reaction, David decided to risk it. He moved very slowly up her legs to gauge a reaction. There was none. By this point, he had moved under her skirt and reached her panties, which he noticed were lacy blue.

"Kinky," he thought. By now, the pull had strengthened again and became someone of a vacuum, sucking him into her vagina. This again had him pause. He just wanted to see her pussy. He didn't want to enter it. He discovered that while the vacuum was very strong, he could still resist it without too much trouble if he didn't want to enter her. However, the more he thought about it, the more curious he became. Why is this feeling telling me to enter her vagina? What would happen? He had taken multiple risks in getting this far, so he decided he might as well take one more. David stopped all resistance and allowed the vacuum to suck him into her pussy.

While she hadn't felt him crawl up her legs, there was no way the woman could ignore the sensation of something entering her pussy. She immediately became aroused, and her body started to spasm while her eyes rolled up in the back of her head. She then collapsed in her chair, with her head on her desk. A couple seconds later, David woke up and groaned.

"What happ-" he immediately paused. The voice that came out wasn't his. It was much higher pitched, almost like a female's. Why did he have a girl's voice? Upon thinking that through more, the question changed. Why did he have a voice at all? He couldn't speak as the blob. He then raised his head and looked around. Wait, his head? He lost his head. And why couldn't he see all around him anymore? It was like he had eyes now. As he moved, he corrected that statement. He had a body now! But how? He then recalled what he had been doing before blacking out and had a hunch what had happened.

First he raised his hands to his eyes. They were much smaller than his old hands, and his nails were blue and manicured. He then looked down to see his legs, but his vision was blocked. Two large mounds protruded from his chest, covered by a blue lacy bra and a green blouse. Pushing himself away from the desk, he stretched his legs out to get a good look at them. They were long and smooth, and covered by a black skirt. Past his legs were his feet. They were inside a pair of high heels, and his toes had pink nail polish on them. Finally, he saw a small mirror on the desk, and the reflection in it confirmed his earlier suspicion. Staring back at him was the face of the woman he saw earlier, her green eyes and the pink lips of her mouth wide open in a state of shock. Looking around, he saw a name plate on the desk as well. Taking it in his hands, he read the name of his new identity.

Dr. Natalie Gordon

'Natalie' put her name plate back and took a second to consider her situation. When he entered her pussy earlier, he must have possessed her body. But how much control did he have over her? He performed a couple of tests, such as wiggling her toes, blinking her eyes, opening and closing her hands, and so on. From what he could tell, he had complete control over her and could move her body as much as she could. What's more, he felt no resistance from Natalie herself trying to regain control. However, he also noticed that while controlling her body was basically the same as controlling his own, her body felt weird. Foreign.

A knock on the door brought 'Natalie' out of her thoughts.

"Dr. Gordon, may I come in?"

'Natalie' put her name plate down and responded, "Yes, come in." Turning her visitor away could arouse suspicion, and while acting out of character could do that as well, she thought she could fake it for short conversation. Her door opened, and a soldier walked in.

"Dr. Gordon, the fire in the storage room was put out. We need you to lead the process decontaminating the room and salvaging any samples are still intact."

'Natalie' suddenly became very worried. She was just a high school student! She didn't know how to do any of this. However, refusal to comply would definitely arouse suspicion, so she had to try. As she stood up, however, she quickly realized two things. First, a female body had very different proportions. Second, high heels were not easy to stand in. These two facts hit her about the same time her ass hit the chair. Her worries increased dramatically. How would she be able to pass herself off as Natalie like this?

As she had these thoughts, a new feeling came over her. Insider her body, she felt part of her slime body converge at the bottom of her back. She then felt that part move up her back, through her neck until it arrived at her head. Once there, the slime located her brain and sunk into it.

Almost immediately, 'Natalie' closed her eyes as she felt a barrage on her mind. New memories, thoughts, feelings, personality traits, and much more entered her mind and became a part of her. Starting from her head, she then felt a "wave" move down her body. As it passed, her body tensed for a second, then relaxed. Her posture shifted to a more "natural" position. And then, the feeling was over and replaced by a feeling of bliss. Natalie then opened her eyes and addressed the soldier.

"Johnson, I'll be there in a moment. I need to look over some things first."

"Alright." After Johnson left the room, Natalie again reached over for her mirror and looked in it. It was the same face she saw a few minutes ago, but it looked different. Instead of looking confused, it had the same expression as she always did. Her body also no longer felt weird and foreign to her. A small smile crept onto her face, and the longer she looked at herself, the bigger it grew.

"Maybe being you won't be as bad as I thought." Natalie stood up and walked over to grab her lab coat, her heels and body balance no longer being a problem. As she did, she took a moment to run her hands up and down her body, lingering a little bit too long on her breasts, butt, and vagina. She walked back to the mirror and smirked at her reflection, licking her lips and batting her eyes.

"Mmmmm. Actually, I think I'll enjoy your sexy body. I mean, my sexy body," she purred in the most seductive voice she could muster. And with that, she walked out of the room with her coat, heels clicking and hips swaying.
