Author's note: Yes, this premise is insane. I'll be honest, it came to me in a dream and once I woke up, I thought it had potential. Probably some people think it should be in NonHuman, but a) said non-human has a human host body and b) if I were looking for "an alien uses an unwilling woman to explore human sexuality" erotica I'd come here first.

"Have you seen Randall? He never came by for my rent check last week. Which is cool, really, but I don't want him to evict me next month or something because I never specifically sought him out or whatever, you know?" Kay took a breath and waited for Jas to answer. She always felt so wrong-footed around her housemate - Jas was so tall, and thin, and clear-skinned, and generally perfect-looking, and, maybe most importantly, cool. Kay had never been cool, and didn't expect to become cool anytime soon. She wasn't tall, she wasn't thin (although that meant she had a pretty good rack), and she didn't have anything like the air of detachment and unconcern Jas kept up on a constant basis.
"No," Jas said, and went back to her magazine.
Randall was, of course, the landlord - the owner of the house where Kay and Jas lived, and resident of most of it apart from their two bedrooms and shared kitchen/dining space. At first Kay had felt some trepidation about living in close quarters with a strange man more than ten years older than her, but he'd never made any kind of move toward her (or Jas, as far as she knew), and she'd never found any cameras hidden in the bathroom.
"It's really strange," Kay went on, feeling a bit of a fool, "that he hasn't been around at all. It's not just that he didn't come for a check, I didn't see him doing any yardwork or anything, and his tv hasn't been on in the evening. That's weird, isn't it?"
Jas shrugged. Going forward, Kay tried to only make sensible declarative statements to her, and to stop worrying about where Randall might be.
Randall turned up that evening, anyway, suddenly appearing in the open doorway after Kay and Jas had finished cleaning up from their dinners. Kay glanced at him, and then looked back - there was something odd about him. She noticed his eyes first, fixed straight ahead; he was turning his head slightly in order to look around the room, and it was also strange that he seemed to be looking at the kitchen as though he hadn't seen it before.
"Hi, Randall," she called out, wiping her hands on the dishtowel. "I can get you the rent - just a minute, I left the check in my purse." As she walked into his field of vision, his face shifted from a blank expression to one of glee, and his left arm shot out abruptly as he grabbed her wrist, bringing her up short. It was so sudden and out of character that she didn't even respond at first, just blinked at him with her mouth open.
"I wonder if you would partake of a meal with me?" he asked, tilting his head a little to one side as he fixed his strange gaze on her. His speech was stilted, with the slightest pause between each word, and even his voice seemed subtly different.
"I, um, I just ate. Are you okay?"
"I am in good health. I am curious as to your health? Will you partake of a meal with me?"
"This ... I ..." It was just so weird that Kay couldn't find any words to respond.
It had been clear earlier that Jas Didn't Care about what was going on, but then she started to seem concerned (still in a dangerous, cool way). "Hey, man, you're acting fucking weird. You gonna ask me on a date, too?"
"Negative. Your form is not as pleasing."
That stunned both of them for its insanity on two levels. Three, really, when Kay considered that their landlord would never ask one of them for date because of a "pleasing form".
"Who are you," she asked slowly, "and what have you done with Randall?"
Randall's eyes unfocused for a full thirty seconds, then refocused. "I have permission from my superiors to enlighten the two of you in order to facilitate my mission. This body has been requisitioned for use in our investigation of the culture of your planet. You will aid me in experiencing human life or consequences will ensue."
"You really think we're buying -" Jas started, but Kay interrupted her.
"What consequences?" Jas gave her a disbelieving look, but it seemed like the right thing to do to kind of play along, if he were really losing it, just until they could call 911 or the police or something.
"I have permission to use physical force if necessary to convince you to do as I require. I also have permission to make limited use of technology when it will be more useful than force. In the event that you alert any other humans to my presence, I will be removed immediately and any of the humans you have alerted will be destroyed. In the event that this body is harmed, I will be removed immediately and the human that has harmed me or allowed me to be harmed will be destroyed."
"Jesus Christ." Jas shook her head. "I can't deal with this. I'm out."
"If you require a demonstration, this can be arranged." Randall held up his right hand, palm aimed straight ahead at Jas. There was a strange buzzing in the air that Kay felt more than heard, and the plate that her housemate was holding suddenly crumbled into dust. "Are you sufficiently convinced?" Kay definitely was, and Jas was quiet, her face having lost all of its cool detachment. "Very well. How are you identified?"
"I'm Kay, and that's Jas - Jasmine."
"Jasmine. You will prepare me a dish of human food. I am to engage in as many human experiences as possible. Kay." His head swiveled around to stare at her. "I have accessed this body's memories, and they show that it finds your form appealing. You will permit me to examine it."
Kay's free arm came up instinctively to cover her body. "What?"
"I must examine your body in order to better understand the female human form." There was a long pause. "Failure to comply will result in the use of force, physical or technological." If he could disintegrate a plate from across the room, then what else could he do? Slowly, she lowered her arm; in response, he let go of her other arm. Kay glanced over at Jas, who raised her eyebrows and then turned back to the refrigerator, clearly thinking along the same lines.
Alien!Randall's first touches were impersonal and light: he gently held her head in his hands, then ran them down her neck, shoulders, and arms. Coming back up on the underside of her arms, he then felt his way back down her sides until he would have had to bend to reach lower. He paused for a moment, then reached directly out and palmed her breasts, squeezing them slightly through her shirt and bra and weighing them. Kay stiffened momentarily, but then, remembering that she had to go through with this, clasped her hands behind her back to make sure that she wouldn't slap his away. After several exploratory squeezes, he began to shift his hands around in order to palpate them in different places and from different angles. It was so clinical that it almost felt normal ... to have an alien feeling her up for research in the middle of her apartment.
Once he was done "better understanding" her chest, his hands moved down to her waist.
That
was less upsetting, and she relaxed slightly - although it was embarrassing to have him playing with her soft, squishy stomach, especially in front of Jas and her solid abs. Then he moved lower, running his hands over the front of her jeans, briefly prodding between her legs before moving to the back. He seemed fascinated with her ass, squeezing, weighing, and inspecting each cheek in about the same way he'd dealt with her breasts. In order to fondle it he had to step closer, pressing himself up against her, which let her feel that he - well, his body - was getting hard.
"Food's ready," Jas said, interrupting his concentration and setting a plate of spaghetti on the table.
"That is welcome. I am eager to try human comestibles." He let go of Kay immediately and sat down (not gracefully) in front of the plate. "Jasmine - you will sit here. Kay - you will sit there." He indicated the chairs on either side of his, and the two girls sat in them, not looking at each other. Or at least, Kay couldn't bring herself to look at Jas. When she finally did, Jas was giving her a scornful glare, and she looked back down at the table.
"This food is problematic," Randall complained. Scooping the pasta up with the fork was a failure, and so eventually he picked it up with his bare hands and brought it to his mouth. Evidently, based on the noises he made, he enjoyed it. When he was done, he sat straight in his chair again. "It was still agreeable. In the future Jasmine will prepare meals at whatever frequency is normal for humans for this unit."
