Work Text:
The facility was quiet. The large industrial fans embedded within the ceiling whirred quietly in the background, siphoning the humidity out of the large room, though a cloying dampness hung in the air and clung onto the metal walls nonetheless.
Mira could hear a faint splish-splashing as she entered. Her footsteps echoed around the large space, and the splashing became more excited. Mira's subject knew she was here.
"Mira!" a bright voice chirruped, and Mira smiled despite herself.
In the center of the room was an enormous pool, 15 meters long, 12 meters wide, and 12 meters deep. It had been specially built to house one of Mira's—no, one of science at large's—most incredible discoveries: a merwoman, straight out of legend. With a humanoid upper body and a lower body consisting of a large, powerful peduncle that ended in a beautiful iridescent purple fluke, her subject was an incredible union of beauty and biology.
As Mira got closer to the pool, she saw a flash of scales beneath the water before unkempt purple hair breached the water, followed by earnest brown eyes and a grin.
"Hi, Rumi," Mira greeted warmly.
"You're still here! I thought you'd left already."
It was after-hours, and the entire facility was empty except for Mira.
"Yes, I still have some work to get done," Mira replied, not without some nervousness.
Rumi picked up on the woman's mood, and she tilted her head curiously, trilling questioningly. It was honestly quite adorable. It reminded Mira of a seal. Not to mention her unique vocalizations.
"I'm here to collect a sample of your semen," Mira said as clinically as possible, trying to keep the blush off her face. "We'll try manual manipulation this time."
Rumi looked at Mira with an unreadable expression, though her tail flicked at the water behind her.
They'd tried to collect samples once before. Mira's team had attempted to use a mechanical device to extract her seed, but Rumi had hated it. She'd already been hesitant to try it, and her unease had only escalated to panic once the machine was on her. It had broken Mira's heart to see her in such a state. The sample they'd gotten was barely usable anyway, so Rumi had gone through that for nothing.
Unfortunately, obtaining the samples was still something they had to do. Rumi had agreed to let them study her reproductive behavior, and the people funding their grants wanted to see it too.
"You're going to touch me directly?" Rumi asked, still with that indescernible tone.
"I-if that's okay with you. I promise I'll be gentle." Mira studied Rumi's face, trying to gauge her reaction. She didn't look happy, but she also didn't look upset, either. If anything, she looked…thoughtful.
"I'll let you get your samples if you give me something in return," Rumi finally said with a gleam in her eye that made Mira's stomach burn.
"I want samples, too. I want you," she said with a devious smirk.
Mira's eyes widened, and then her ears burned at the implication. "I—I—"
"It's only fair, don't you think?" Rumi asked, smiling.
Mira was at a loss for words, not knowing how to interpret Rumi's request. She vascillated between being disarmingly playful and serious so often that it was hard to keep up. Mira wondered if all members of her species were like this or if this was uniquely Rumi.
"You can't be serious," Mira finally replied.
Rumi shrugged, swimming away from the edge of the pool. "No samples for you, then."
"Wait!" Mira cried, reaching a hand out. Rumi floated to a stop.
Mira closed her outstretched hand into a fist and dropped it to her side, shoulders slumped. She considered her options.
Mira could just take the samples by force—sedate her subject, and then take what she needed. But she could never bring herself to do that. Maybe she could have Zoey collect it instead?
No, Mira had more integrity than that. She wouldn't offload her work to other people when she'd promised to do it herself.
"If I say yes…you'll let me collect from you?"
Rumi smirked and nodded.
Mira sighed. "Fine," she said.
Rumi made a happy trilling noise and swam to the edge of the pool again. "How do you want me?"
Mira coughed. "Uh, this will be easiest if you're out of the water, I think."
Rumi heaved herself over the lip of the pool, water sloshing down her large, muscular arms in shimmering rivulets. With a powerful whip of her tail, Rumi vaulted herself onto the concrete floor. Mira stepped back as water splashed near her feet.
"Oops, sorry," Rumi giggled.
"My fault, I should be more prepared," Mira said. She took off her shoes and socks and rolled up her khakis. Then, she tied her hair into a high bun and pushed her glasses higher onto the bridge of her nose.
Rumi's eyes seemed to glitter as Mira walked over to her again, her bare feet creating ripples in the puddles of water on the floor.
"You look so beautiful with your hair up," Rumi said, eyes scanning all over Mira's face.
The scientist coughed again, trying to distract herself from the heat creeping up her neck. "Th-thank you."
Rumi sat on the ground, leaning back on her hands for support. Mira couldn't help but note the way her purple hair framed her face, how plump her lips were over teeth that were slightly too sharp to be fully human, the way droplets ran down her chest and in between her exposed breasts. The gills over her ribs fluttered with every breath. Adapted for breathing both on land and in water, Rumi was truly an incredible organism, and the scientific part of Mira's brain hungered to explore every inch of her physiology.
Mira set her bag on the ground and took out three small plastic cups, and a pair of nitrile gloves. "Do you think you have 3 samples in you?" she asked.
Rumi nodded, eyeing the implements carefully. "My species is extremely virile. Our bodies are designed to create thousands of offspring at a time. You should have no trouble getting the amount you require."
Mira's heart sped up, and she felt a twinge between her legs, a twinge she should not have felt. "Good to know, I'll make a n-note of that in today's report," Mira stuttered. She pulled the gloves on with a snap and turned toward the merwoman. When Rumi caught sight of the purple gloves, she whined unhappily.
Mira furrowed her brows. "What's wrong?"
"I don't like the gloves," Rumi said. "I don't like how they feel."
Mira's hands stilled. "I need them to prevent cross contamination. I don't want to accidentally mix my DNA into the samples."
The corners of Rumi's lips turned down into a frown, and she flicked her tail in agitation. "Fine," she huffed.
Mira gulped and sat down next to Rumi. She looked down the length of her body, noting that the slit in the ventral aspect of her tail had slide open slightly, revealing a small nub that was just barely peaking out—the beginnings of her penis.
Mira's hand hovered over the nub. She looked at Rumi first for permission. "May I?"
Rumi nodded, and Mira licked her lips, focusing on the task at hand. She touched a gloved fingertip to the nub. Her heart leapt into her throat when Rumi gasped, her body jerking.
As if moving by instinct, Mira began rubbing circles around the tip. She watched in fascination as Rumi's penis slowly emerged, hardening and lengthening under her touch. When it was halfway out of its sheath, Mira wrapped her hands around the shaft and began stroking it. Rumi's breaths became labored, and she gripped Mira's clothed thigh with a webbed hand.
Mira's eyes snapped to Rumi's face. She was staring at Mira's hand, her face blushed red, lips parted, fangs peeking out. She had such a desperate, debauched look on her face, it made Mira's heart thud in her chest.
The loose material of the glove dragged over the skin of her shaft, and Rumi gasped, burying her head in Mira's shoulder.
"I—I can't go any further," Rumi gasped out.
Mira's hand immediately stilled. "Why? What's wrong?"
"The—the gloves, they don't feel good, I can't—" Rumi shook her head against Mira's shoulder.
Mira bit her lip. If Rumi truly disliked them that much, she couldn't, in good conscience, continue wearing them. She couldn't do that to her. Plus, if they really didn't feel good, it would impede the collection process. And if going gloveless meant obtaining better samples, she had to do it, right?
Mira peeled her gloves off and threw them to the side. She reached out for Rumi's shaft once again, hesitating only for a second before wrapping her bare fingers around it.
Rumi moaned loudly at the first touch of heated skin against her most sensitive area. Shivers wracked her entire body. Mira could feel her hot breath beat against her neck. She began pumping once more, and pleasured moans spilled softly from Rumi's lips.
Observations started flying through Mira's mind as she tried anything and everything to mentally separate herself from what was happening in the moment.
Physiological responses to arousal: dilated pupils, bloodflow to erogenous zones. Shortness of breath. Increased heart rate. Increased blood pressure likely.
"Mm—Mira, I'm—I'm going to—"
Mira just barely had the presence of mind to grab the first cup before putting the opening right at Rumi's tip. The merwoman moaned as a thick, white substance shot from her tip and into the waiting cup. Mira continued stroking her, milking her for every drop, until the flow petered out. Mira could feel the warmth of the sample through the plastic of the cup, and she became hyperaware of her own heavy breathing and the way her heart hammered in her chest.
With shaky fingers, she screwed the cap back on, and set it aside to pick up the second cup.
"How are you feeling?" Mira asked, feeling the need to check in.
Rumi removed her head from the crook of Mira's neck. She had a dopey, wistful smile on her face. "Good," she trilled, nuzzling back into Mira's neck. The scientist cleared her throat.
"Very good. Are you ready for the next one?"
Rumi nodded against her neck.
Rumi whimpered when Mira held her again and began pumping to slowly build her back up. As she worked her up, Mira became acutely aware of her hardened nipples rubbing against her shirt, and a sticky wetness between her thighs that had nothing to do with the water pooled on the ground.
After a few minutes, Rumi sputtered out, "Mira, I—I'm close again—"
The scientists quickly scooped up the second cup just as Rumi's seed exploded from her tip once again.
"That's it, that's a good girl, give me everything," Mira found herself saying. Rumi wailed, gripping onto her shirt, as she bucked into Mira's hand, pumping out every last drop.
Mira screwed the cap on and set it aside to encircle her arms around Rumi's trembling form. She could sense that the merwoman needed it in that moment.
"Rumi, are you alright?" Mira murmured, stroking her hand down Rumi's smooth, scaly back. Rumi shivered again, but nodded. Mira gave Rumi a few moments to calm down, then said, "We just have one more. Are you ready?"
Rumi huffed but nodded her head, pulling out of Mira's embrace to lean back on her hands. She stared at Mira with pupils blown wide, a pretty pink dusting her cheeks. Mira wondered if her eyes looked the same. She broke eye contact to focus back on her task, once again wrapping her hand around the shaft, which was hot and red now from so much stimulation.
Rumi shook and squirmed from oversensitivity. Mira lightened her touches, using a gentler contact, knowing that it wouldn't take much for a third time. Rumi's mouth hung open as she panted, her breasts heaving. Mira's traitorous eyes fixated on them, the way her nipples hardened with arousal, and she felt her own harden in response.
Mira dragged her eyes back to her hands, gulping. Rumi's vocalizations were getting louder now as she approached her third peak, whimpering and twisting in Mira's grip.
"I'm almost done, Rumi," Mira said.
Rumi simply whined in response, too far gone for words.
"I know, I know. I'll call Zoey so—"
Rumi's hips jerked, and she came without warning. Mira quickly grabbed the third cup, aiming the opening toward Rumi's tip. Heat pooled low in her belly as drops of Rumi's seed spilled onto her fingers, leaving burning trails over her skin. Mira's center throbbed. She closed her eyes and took a steadying breath.
Easy now, Mira. Just do your work.
Without warning, Rumi leaned forward, grabbing Mira's face and pulling her in.
"Wait—"
The word died in her throat as Rumi pressed her lips to Mira's, her webbed hand sliding down Mira's neck, against her fluttering pulse. Mira's brain short-circuited as heat exploded across her cheeks. Rumi smelled like the ocean, like salt on the sea breeze.
She felt strong arms wrap themselves around her lower body, and next thing she knew, she was being dragged onto Rumi's lap. Soft lips pressed against her neck.
"You got your samples."
"Rumi—?"
"I want what was promised."
Sharp teeth nipped at her neck before being soothed by a kiss.
"I want you."
Mira felt Rumi's hard member through the seam of her pants, pressing insistently against her hot center. Mira moaned, her once-ironclad will crumbling in the face of Rumi's body pressed against hers.
Rumi grabbed Mira's hips in her large hands, encouraging the woman to grind against her as she captured her lips in another kiss. Mira kissed her back, writhing in Rumi's hold. The throbbing in her center had become a pounding ache. Lips still glued to Rumi's, Mira reached down with uncoordinated hands, undoing the button and zipper of her pants.
"Here, Rumi, let me—"
Mira separated from Rumi far enough to push her pants down around her knees, then leaned back in, unable to stay away for long. The pants around her legs meant that Mira had to fold her legs against her chest to be able to lean in close enough to kiss Rumi again, but it was hardly an issue—Mira was quite flexible, after all.
Mira could feel the underside of Rumi's shaft rubbing against her through her soaked panties. Each time it nudged against her engorged clit, it shot sparks up her spine.
"M-Mira, I want to cum again," Rumi said. Mira felt herself clench, going back and forth with herself on whether she was really going to do this. She was sure that having intercourse with her subject was illegal, if not at least unethical, even if the subject in question could give consent. It also had to be unsanitary to have sex with a fish person, right?
Somehow, these thoughts thrilled her instead of discouraging her. She was already dry humping with said fish person. In for a penny, in for a pound, right?
Letting go of all her inhibitions, Mira said, "No, not yet. I want to feel you."
Rumi's eyes widened, and her cock jumped. "R-really?"
"You wanted my sample as well, didn't you?" Mira asked with a raised brow.
With one hand, Mira hooked a finger into the gusset of her panties, pulling them aside and exposing her hot, swollen lips to the cool air of the room. With the other hand, she grabbed Rumi's smooth shaft and aimed it at her entrance, feeling the pointed tip sink into her heat and slowly open her up.
Rumi's head fell back with a moan as she was enveloped in Mira's warmth. "Oh, oh, Mira, you—you feel so g-good," she whimpered.
Mira sank all the way down, ass flush with the scales of Rumi's tail. Rumi was so large, so deep inside her, it made her breathless. The stretch burned, but it only heightened Mira's arousal.
"Ohh, fuck, Rumi," Mira groaned, forehead falling against Rumi's chest. She'd done it. She'd let what was essentially an animal inside her in the most private, intimate way. She felt dirty, and she loved it.
Mira began grinding in Rumi's lap, using her large cock to stimulate her sensitive front wall. The rough scales of Rumi's body added extra friction against her clit, and Mira was addicted to the feeling.
Mira rode her savagely while Rumi fucked up into her, using her hands on Mira's hips to slide her down onto her cock, sinking so deep that it punched moans out of Mira's throat every time.
She felt her breath quicken, her pussy clenching and fluttering around Rumi's length, and that familiar, indescribable pressure built inside her. She and Rumi were rutting against each other like desperate animals now, helping the other person chase their high.
"Mira, Mira, please, I can't, I'm about to—"
"Hold on for me, Rumi, just a few more seconds," Mira ground out, edging herself closer and closer to the precipice. "I'm—almost there—"
Rumi whined, wrapping Mira in her arms, hips moving frantically as she tried to stave off her orgasm.
When she felt herself teetering on the edge, Mira gasped, "Now you can—I'm about to—"
Rumi keened, high and broken, as she filled Mira to the brim with her seed. The pressure inside of Mira broke and her moans mixed with Rumi's as she climaxed, squeezing impossibly tight around the merwoman. Her pussy gushed with a mixture of their releases, translucent white spilling all over Rumi's lap and Mira's thighs. This wasn't the clean, clinical ejaculations of earlier—no, this was frantic, dirty, and messy.
They both trembled in each other's arms as they took deep breaths, enjoying each other's warmth in the afterglow. Mira reached up, cupping Rumi's cheek, and brought her face down to kiss her tenderly.
"That was my favorite way of collecting samples so far," Rumi said once they broke the kiss.
Mira laughed lightly, shaking her head. This was definitely not going to make it into the report.
