“Sorry, what?” Ensign Raymond Cruz blurted out.

Lieutenant T’Praul cocked her head, “Sexual intercourse, Ensign. I would have assumed that you would be aware of the concept.”

“I… I know what sex is,” Ray responded, “But you asked…”

“If you wished to engage in sexual intercourse with me.” T’Praul responded. She had a standard severe Vulcan haircut and, given the subject matter, Ray couldn't help but notice the ample breasts contained within her blue uniform.

“Uh…” Ray shifted uncomfortably, not knowing how to respond.

“There are important scientific questions to be addressed. During our bio-sociological survey of Kiimas IV I became intrigued about the potential of orgasms to improve mental faculties. While I have read the relevant scientific literature there is no substitute for conducting hands-on empirical research."

“But… why… why me?” Ray responded. Despite, or even because of, T’Praul’s mannerisms his eyes kept being drawn to her chest and he could feel himself starting to get hard.

T’Praul raised an eyebrow at Ray’s question. “It is the only logical decision. Of the 47 humanoid males serving onboard the USS Ishtar, you are the only one who is not: in a monogamous relationship, in my chain of command, or Andorian.”

“But, uh, don’t you have that seven year thing,” Ray blurted out.

“The pon farr is a natural part of a Vulcan's life cycle to spawn new offspring,” T’Praul explained dryly, “Accordingly, among my people it is considered to be the only logical time for sexual intercourse. But through my work on Kiimas III, the sheer prevalence of non-procreative sexual intercourse made my question whether any of my assumptions were, in fact, illogical.”

Ray’s mind was spinning. This was not remotely how he had expected the afternoon to go after he had gotten off his shift. “Ensign,” T’Praul said interrupting his thoughts, “My time is limited. I require your response.”

Ray took a deep breath, trying to gather his thoughts as T’Praul stood there, cool and composed, waiting for his answer. Finally, he looked up and met T’Praul’s steady gaze. “I... I’m willing to participate in your research,” he said.

T’Praul’s nodded in acknowledgement. “Very well, Ensign. Please accompany me to my quarters.” As they walked down the corridor she continued: “Given that the average Vulcan female is approximately twice as strong as a human male, there are certain sexual positions that would be inadvisable. Ah, here we are.”

The door to T’Praul’s quarters slid open and Ray followed her into the spartanly decorated room. “Please disrobe and undergo a sonic shower to ensure cleanliness,” she said as she briskly slid out of her uniform. She was braless and her breasts were even larger than they had appeared in her uniform, with bold dark, almost-black, nipples. Ray gawked and his eyes trailed down her muscular body to her thick mane of pubic hair.

“Depilation around the vulva is illogical,” T’Praul told him seeing his gaze, “Please disrobe, Ensign.” Ray quickly averted his eyes and began to undress. Under T’Praul’s cold gaze, he stepped into the sonic shower, letting the tingling sensation cleanse his body as he tried to steady his breathing. As he emerged from the shower, T’Praul was waiting for him, her expression unreadable. She took out her tricorder and moved with precision, as she leaned down to capture his lips in a deep but passionless kiss. Ray felt a surge of desire coursing through him as he responded eagerly, his hands exploring her smooth skin.

T’Praul directed him through each touch, each caress, with a detached yet purposeful demeanor that only fueled his arousal further. She placed both his hands upon her breasts and then broke the kiss to look at her tricorder. “Fascinating,” she said picking up a PADD and jotting down a few notes, “Ensign, please place your tongue on my right nipple.”

Ray leaned in and, with a tentative flick of his tongue, complied. The taste of her skin was both unfamiliar and intoxicating as he felt her nipple hardening under his tongue’s touch. He moved up his hand, to tweak and tease her other nipple. “Interesting,” she noted, her brow furrowing slightly as she analyzed the readings. “Your heart rate has increased by approximately 30%. This indicates a heightened state of arousal. The literature does not consider either the human tongue or fingers to be an erogenous zone.”

Ray was now fully licking and sucking T’Praul’s now fully-hardened nipple as the tempo of his fingers increased on her other one. “Ensign,” T’Praul said, “Can you address my statement?”

“Uh, okay,” Ray said disengaging, “Well, it’s uh, y’know, it’s hot. I’m getting to second base with a hot naked alien.”

“‘Hot’, ‘second base’ - fascinating idioms.” T’Praul said jotting down more notes on her PADD, “Well, Ensign, your administrations have produced the requisite vaginal mucus levels in me and you are fully tumescent. You may now proceed to penetrate my vagina with your penis.”

T'Praul turned her back on Ray and walked briskly towards the bed. Ray could not help but ogle the most muscular ass he had ever seen. She positioned herself on all fours on the bed in a clinical manner. Ray now had a good look at her Vulcan cunt, his line of sight unencumbered by her pubic hair. It was engorged with a faint greenish tint. Ray approached T'Praul and placed himself behind her. He grasped her hips, marveling at the firmness of her muscles beneath his fingers. Slowly, he guided his erection to her entrance.

"Proceed, Ensign," T'Praul instructed, her voice as calm and level as if she were instructing him on how to calibrate a sensor array.

Taking a deep breath, Ray pushed forward, sliding into her. He gasped at the sensation - how hot it was, almost scorching compared to a human woman. T'Praul's eyes widened slightly, the only indication that she felt anything at all.

“Please begin thrusting at a moderate pace."

Ray complied, establishing a steady rhythm as he moved in and out of her. T'Praul's inner walls clenched around him with surprising strength as he thrust, sending waves of pleasure through his body. Ray couldn't help but moan softly, overwhelmed by the intense sensations. "Fascinating," T'Praul remarked, her voice only slightly breathier than usual. "The muscular contractions of my vaginal walls appear to be providing you with significant stimulation. Please describe the sensations you are experiencing, Ensign."

Ray struggled to form coherent thoughts as he continued to fuck her. "It's... it's incredible," he managed to gasp out. "So tight... and hot... like nothing I've ever felt before."

"Noted," T'Praul said, jotting down his response on her PADD. "Now, please increase your pace and force by approximately 37%."

Ray gripped her hips more firmly and began to fuck her faster and faster. T'Praul's body rocked with each powerful thrust, her breasts swaying beneath her. Ray's fingers dug into the firm flesh of her hips as he pounded into her with increasing intensity, filling the room with the sound of skin slapping against skin. "Ensign, I am experiencing a heightened state of arousal. Please reach around and stimulate my clitoris." Despite her outward composure, her breathing had become slightly labored.

Ray eagerly complied, sliding his hand around her hip and down to the apex of her thighs. He found her swollen nub, slick with her arousal, and began to rub it in small circles. T'Praul's body tensed at his touch. "Fascinating," she murmured. "The combination of internal and external stimulation is producing a most intriguing physiological response in me."

Ray, lost in the sensations, barely registered her words, he could feel the pressure building within him, a telltale sign that he was approaching his climax.

"Fuck," he gasped out, "I'm getting close... I'm going to...”

T’Praul’s hand darted out from tapping on the PADD and moved behind her to grab Ray’s hip and hold him in place. Despite the awkward positioning, it was enough to immobilize him from thrusting forward. “You are not yet to ejaculate,” T’Praul instructed, her voice breathier than before, “Continue your clitoral stimulations”

Ray struggled against T'Praul's iron grip, his body trembling with the effort of holding back his orgasm. He focused on circling her clit, increasing the pressure and speed of his fingers. T'Praul's breathing became more ragged. "Fascinating," she whispered. "I appear to be approaching… climax. The sensations are... most illogical."

T'Praul's inner walls began to pulse harder and harder around Ray's cock, squeezing him with almost painful intensity. Her back arched and a small gasp escaped her lips - the first truly uncontrolled sound she'd made. "Now, Ensign," she commanded, releasing her grip on his hip. "You may ejaculate."

Ray didn't need to be told twice. With a groan of relief, he thrust deeply into T'Praul and came hard, harder than he had in his entire life.

T’Praul broke the silence. “That was a very productive research session. I trust you will continue to assist with me with further research sessions. We have many more experiments to perform.”
