Leave.

“Perhaps it would be good to make some headway.” Ethan decided. “This host doesn’t know much, but he could be connected to those who could prove more useful.”

Tracy understood immediately, since it was her mind making the decision as well. She rose from her place on the bed, climbing atop her husband once more. The brunette straddled her husband’s chest, placing her hands on his pecs. “It’s a pity to abandon such a fine form.” She said, gazing upon her own tits. “Oh well.” She shrugged.

Ethan brought his wife in for a kiss, which she eagerly reciprocated. The two made out again for a moment, their tongues dancing in one another’s mouths. Then the transfer was initiated, green goo sliding from Tracy’s lips to his. Glob by glob of the slime passed between them, and the passion from Tracy slowly faded until Ethan found himself kissing a woman he had no possessive control over. Carefully, he laid his naked wife back down onto the bed, fast asleep.

“Well, that’s that.” Ethan said, feeling completely filled by slime once again. It was a strange feeling, having carried some of Tracy’s memories and feelings back into him. Finally he knew what it felt like to be fucked by himself! He settled in for the night, knowing it would be a busy day tomorrow.

The state of Earth’s finest militaries seemed almost laughable. Truly, Ethan had to keep himself from snickering as he waltzed onto the military base he had served at for years. Everything about it, from the uniform he wore to the concrete structures he walked past and the supposedly state-of-the-art weaponry the guards carried were downright primitive. The slime that controlled his body had seen far more impressive guns on a dozen other worlds. Perhaps even the last advanced ships of the Imperial Fleet could conquer this planet in a month?

But the slime knew better. Its job was to infiltrate and learn, not to assume and jump to conclusions. More information would be necessary. And Ethan knew likely where to get it.

Flashing his ID card to the guard by another gate, Ethan proceeded into a storage area. Inventory was his livelihood within the military branch known as the United States Air ****. He managed every last item in a large warehouse full of top-secret materials, the contents and functions of which were unknown even to the majority of Earth’s nations. It sounded like an exciting job to him when he signed up, but Ethan found it extremely boring. He had imagined flying airplanes or something, and instead was a glorified clerk.

The possessed soldier sat himself down at a desk, browsing through requests for information and materials from people across the base. He found himself having even less interest in this work than usual. Suddenly, a name came across the screen he recognized. He immediately highlighted and approved it, smiling as he did so. He reached down and massaged his dick, which was as hard as it had ever been this morning. Maybe it was the sight of his clueless wife in the morning, waking up naked with nothing but memories of fucking her husband raw the night before, but he’d stayed hard the whole morning. He’d even had to tuck it into the waistband of his pants just to hide it. But perhaps it was something else. Perhaps he was starting to get off on just being a human, hiding underneath this guy’s skin.

About an hour later, the door to his office opened again, and another soldier walked into the room. Ethan stood, showing respect to a superior officer. “Lieutenant.” He said, saluting.

“At ease, Sergeant.” The lieutenant said, handing him a paper. “This came across my desk just now. You have those filters I ordered?”

Ethan smiled. “Absolutely. Follow me, please.” He led the lieutenant out of the office, into the maze of shelves. They went past crates upon crates, moving to the more isolated area of the warehouse. It was the one place Ethan knew for a fact cameras didn’t watch.

“You know Sergeant, I ordered these filters a week ago.” The lieutenant continued sternly. “I’ve been thinking about you giving them to me all this time.”

“My wife might not appreciate it if I give them to you too often.” Ethan replied with a smirk.

Finally the two arrived to their secluded spot. It was dark enough here that not even a passerby could see them.

The lieutenant smiled, dropping her pretense of authority. She took off her cap, showing her close-cropped blonde hair. “Now, as your superior officer, I order you to fuck me.”

The two embraced passionately, Ethan’s tongue diving into Casey’s mouth. His mistress braced herself against a nearby box, leaning back as the man reacted to her advances with aggressive passion. She brought her hands around his head, feeling his prickly short hair on the back of his skull.

“Oh baby, I got wet just seeing that notice.” Casey laughed, doing her best to keep her voice down. “It’s like a fucking Pavlovian response now.”

The slime searched the back of its host’s memory, realizing the reference she was making. “You just know you want me that badly.” Ethan replied smartly.

The lovers undid one another’s belts. Ethan moved to pull apart Casey’s coat, but she grabbed his arms. “Sorry, lover boy. You’ve only got me for about fifteen minutes. Better keep the uniform on.”

Ethan smiled, instead moving down to unzip her pants. “What could be more important than this?”

Casey frowned playfully. “That’s classified, Sergeant.” She said, bringing back the commanding tone she only used with him in public. Then she giggled a little girlishly as she was pushed back again onto a box, her pants around her ankles. The smooth surface of her bare ass met the cool surface of the crate, and before she knew it Ethan was down between her legs, pulling aside her plain cotton panties to hungrily lick her.

Ethan found the taste of a human woman quite pleasing, especially now that a horny slime was controlling his body. He was quite familiar with the musky smell of Casey’s cunt by now. He looked up to see Casey bring a hand over her mouth, stifling her pleasured gasps as he ate her out. There wasn’t much danger of discovery back here, but they always wanted to be safe. Her eyes rolled back in her head, and she laid back on the crate to enjoy the sensation. A perfect position to start the process.

A small lump traveled up Ethan’s throat as he continued the cunnilingus. It reached his mouth, and a small green glob appeared. It moved on its own over his tongue, into Casey’s waiting pussy. The moment it dissolved into her, information began to flow into his head.

Casey had sworn she felt something go into her, but she dismissed it as Ethan’s tongue. The slime could discern she worked at a highly classified lab, and had a meeting with a colonel in half an hour. This was a better host. Casey definitely didn’t have enough slime in her to be controlled, but that would soon change. Ethan felt pangs of pleasure in his dick as the woman he was partially mind-linked with orgasmed.

“Fucking hell, baby, that was good.” Casey moaned. Ethan was always able to make her cum. She didn’t care that he had a wife, just so long as he gave her a good dicking down whenever she got horny. If anything, being someone’s mistress turned her on even more. She realized he had stopped licking her pussy, and looked up just in time to catch a glimpse of Ethan push his dick into her.

Both of them groaned as they began fucking in earnest. “Jesus, Sergeant, maybe I can give you a few more minutes of my time after all.” The blonde lieutenant laughed, feeling yet another orgasm start to build in her gut.

Ethan replied with a smile. “That won’t be necessary Casey.” He said, in an almost unusual tone as he pounded her pussy. “Someone might start to think something’s wrong.”

“Oh yeah, and what’s that?” She moaned, playing along with what she thought was a bit of roleplay. “That I’m fraternizing with a man of lower rank?” Her climax was seconds away.

“No.” Ethan grunted, feeling slime swell his balls. In preparation “That you’re an alien’s disguise!”

At that moment, both of them came, Casey for the second time. She barely even heard whatever Ethan said. Her orgasm was earth-shattering, even bigger than the previous one, as though it were amplified. Ethan came load after load, shooting slime directly into her. A goofy smile was on his face, the slime literally feeling itself cum itself into a new body. As Casey began to feel a hazy sort of darkness fall over her mind, she came yet again. She couldn’t even question what was somehow still being shot into her womb in rope after sticky green rope. Ethan kept thrusting and thrusting, cumming and cumming, until finally he fell to the floor ****.

Casey took a deep breath, sitting up slightly to look herself over. The slime had fully taken control of her by the time Ethan had hit the ground. That time, it was somehow a little easier to wrest control of her body. Perhaps it was best to try possession at the same time as the host had an orgasm.

“Now that was worth my time.” Casey grinned, the last stray drops of goo sliding into her cunt. She got back up, pulling her panties and trousers up her legs. She thought about reversing the process and stripping down a bit further, but there was no time for that.

“Well, Sergeant, I have a meeting to make.” She declared, looking down to the sleeping Ethan. There was still a dumb smile on his face, as though he were having a pleasant dream.

“Oh, whoops. Looks like I missed a little.” She knelt down and licked one last stray green dribble off the head of his softening penis. She swallowed it down happily. Even in a different body, the slime still thought it tasted great.

With that, Lieutenant Casey straightened out the rumpled bits of her uniform, put on her cap, and departed. She had a meeting to make, and she was feeling very satisfied.
