Well, this is a weird one, but that's what we do here!
As usual, all the characters depicted are consenting adults over the age of twenty. Also, just so you know, Damien is a bisexual man and this comes into play during the story.
Thank you and enjoy!

The field of alien botany exposed one to many interesting and thrilling possibilities. As humanity reached greater heights in galactic exploration, there was an endless stream of new plant species to examine and explore. And nothing was more exciting than the discovery of the more exotic and complex specimens.
"Especially one that could be interacted with in the way that this one can," Damien thought, surprisingly unashamed.
A colleague of his, Sarah, had recently been given the opportunity to go on a guided expedition to an alien planet and learn about its native flora. She had come across one in particular that she had been allowed by the locals to return to the lab with.
Its native name translated roughly to "flowers from drinking man's milk". The plant lived off of the usual sunlight, but also bugs and, when the opportunity struck, semen, which reportedly made its luminous flowers bloom in a wider range of colours and gain certain healing properties.
Sarah graciously accepted the donation of the plant and rushed it back to HQ, eager to begin experimenting. However, she personally could not partake in the plant's most interesting quality. That was where Damien came in. He had wholeheartedly agreed to fuck a plant for science. He loved his job; strange as it was.
He had been given a rundown of what had been discovered about the plant's physiology and consented to the possibility that the plant would be injecting him with a powerful, but perfectly harmless, aphrodisiac to prolong its feeding. No complaints there.
They picked a day where the greenhouse would be a little less humid given the activity that would be taking place. Damien entered the building, followed by Liam, a young intern who was there to take any necessary notes from close observation. He looked to be in his early twenties (at most only about ten years younger than Damien), and seemed eager to learn but also embarrassed.
Damien clapped him on the shoulder. "Nothing you haven't seen before, right?"
"Right," Liam said, his face flushing a bright red.
"And there's no problem with ducking out if it's too much, okay?"
Liam nodded, clutching his note-taking tablet with resolve. He probably wasn't going anywhere, wanting to continue making a good impression.
"The plant's just up ahead," he said, pointing.
"Good."
The two of them trudged through the greenery for another minute before coming across the isolated plant. It was large, coming up to Damien's chest. It had a vaguely upright eggplant shape to it; bulbous and thick at the base and tapering near the top. There were various layers of leaves, and thin protrusions that carried many dormant flower buds.
"It smells so sweet," Liam commented.
Damien deeply inhaled the almost sugary scent. He sighed, contented.
"Well, no time like the present," he said.
Liam assisted Damien in setting up, which only really consisted of standing the camera up on its tripod. It would record the process for future reference and provide a live feed for Damien's other colleagues to observe—for intellectual and safety measures.
Oddly enough, the clearly sentient plant had a sort of system of consent; it would only engage with a person who approached it purposefully and in the nude. So, Damien made quick work of stripping off his clothes. The only thing that remained was the sensor around his left wrist which would track his vitals and measure the amount of the plant's aphrodisiac in his system. He handed his clothes to Liam who dutifully folded them and placed them in a pile nearby.
The intern then stepped behind the camera so as not to be in the way. He turned it on, checked the feed, and gave Damien an enthusiastic thumbs-up.
Damien faced the camera.
"This is Dr. Damien Turner, with the Intergalactic Flora Experimentation Facility," he began. "I am about to participate in our very first test of the unique qualities exhibited by Specimen #703 from the planet Vetreterra. Once the feeding is complete, we should be able to harvest the enriched flowers, which may serve as a great asset in the medical field. I will now approach the subject."
With some trepidation, Damien closed the distance between him and the specimen. As expected, he really felt no sexual excitement towards the plant as it was. It hardly resembled any human or alien partner he had ever had in the past. However, a depraved part of him in the back of his mind gained a little arousal from the knowledge that he had an audience for this.
As he stood inches from 703, the tapered part at the top of the plant opened and a few slick green tendrils emerged. They felt him out, gently caressing his chest, abdomen and thighs. When he didn't make a move to leave, one of them wrapped around his leg to pull him in closer, while another split open four ways at the tip. The latter hovered in front of his face for a moment, the sharp spines inside glistening and dripping with clear liquid. It latched onto the juncture between his neck and shoulder.
The initial puncture stung quite a bit, which made Damien hiss, but any pain was quickly lost in the sudden rush that followed. A heat spread to every inch of his body as the tendril released. His nerves felt ignited and hypersensitive. The air around him moving across his chest as it heaved was enough to harden his nipples. He moaned as the plant's tendrils began teasing them.
"Okay, Dr. Turner?" he heard Liam ask tentatively.
"I'm good," Damien said, his eyes rolling as he felt the heat spreading to his groin. Unable to stop himself, he brought his hand to his swiftly growing erection. His own touch was electric and he nearly cried out in pleasure, mindlessly beginning to stroke himself to full hardness. "So good. So, so good."
