The Male

The alien was not familiar with human anatomy. Which orifice was the best one to enter and which one would be inefficient? With little time to spare, it simply approached the closest human and threw caution to the wind. The slug slithered through the tight cloth the human had and approached the first hole it could.

“The hell…? The fuck was--argh!” The slug could vaguely make out noises coming from the human as his body fell face-first into the water. There were other voices, most likely friends trying to check up on the male, so the slug tried to act fast.

Cells, organelles, organs, and soon the whole human body slowly came under the slug’s control as it bonded with its host. The slug caught a few vague thoughts from the male, mostly panic and confusion, but it cared little and swiftly silenced them. Soon, the male’s body grew warm as a cascade of sensations nearly overwhelmed the slug. First was the male’s dick, risen to full mast at the alien’s invasion. So this human enjoyed penetration of his… anus? The slug made a mental note of that. Next was the lack of air and the water that had made its way to the lungs.

'Oxygen! This body needs oxygen!'

With its new powerful, muscular legs, the slug caught itself and stood back up. It gagged and coughed as it took its first new breaths inside of a human. Immediately, it felt the cool chill of the night air against the male’s wet skin and heard the cries of the other humans by the bonfire.

‘So, this is a human,’ the slug thought it—himself.

“James? You okay?” The female asked as she waded through the waist-high water. “What happened?”

“Just… tripped,” the slug said in his new deep voice. So his new name was James. And this one was... April. He skimmed through his host’s memories and found the process much harder than his previous infiltration attempts. Were humans more complex than the previous hosts? No, the real reason was...

‘Ah, this human is intoxicated,’ James thought to himself as he recalled the numerous beers James had drunk before skinny-dipping… well, as close as one could be while still wearing a pair of briefs. The slug had caught James just as he was pulling them off, allowing for easy access to his ass.

“Head kinda hurts… Think I’m gonna take off.” The new James tried to put on his usual smile, inwardly hoping that it wouldn’t look suspicious.

To April, it must’ve as she remained incredulous. “Are you sure? You seemed to excited to go skinny-dipping with me…” her voiced sounded hurt, but James cared little. Right now, he needed to think about his next move and how to handle his intoxication.

Without responding, James turned around and made his way to shore. “Jerk!” April called out, but the alien had little context for such a word. Had the alien spent some more time skimming James’ mind and figuring out human etiquette, he would’ve also grabbed James’ discarded clothes before leaving the bonfire and making his way to his host’s domicile: a frat house near the edge of the local college’s campus.
