ღChapter 5~ Speculate | Mini Masterlist | Chapter 7
After consuming some energy, as Hongjoong put it, showered and rested, a new experiment was born from your time with Yeosang.
Your human clothes were folded up neatly and left in the small chamber where you and San had rested. Instead you wore the same robes the aliens donned the majority of the time. That made things easy but removed some of the fun of discarding clothes or even fucking in them.
“Good Morning,” Seonghwa greeted you.
Mingi had escorted you and San to the observation room, all the while ogling your breasts in the newly donned robe.
“Seonghwa!” You squealed.
You moved to snag him in a hug, feeling a rush of endorphins that he was still around, but Mingi put his hand up, halting you.
Mingi shook his head. “Seonghwa is here as an observer. He will not be participating today.”
You looked at Mingi in complete confusion and then whipped your head back to look at Seonghwa’s face. “Is it true?”
Seonghwa pressed his lips together. “I was out of line before. I should have remained detached and simply watched. Participating was not my role.”
You couldn't help but feel disheartened. You turned back to Mingi. “If not Seonghwa, then who? Will I get to meet Jongho?”
Mingi shook his head again, pursing his lips to the side. “We brought in another human.”
Wooyoung showed up with a human much taller than him. “I’m here, I’m here. No one inform Hongjoong I was late.”
The sharp alien language cut through the room, belying that Wooyoung had indeed still been caught. Wooyoung’s face fell. “Ah, shit.”
Mingi left, taking Wooyoung with him, but not before you overheard the shorter alien grumble about his time coming soon.
“San, my moo--” Seonghwa shook his head as if to get his head on straight. “I mean, Babe, this is Yunho. He is also a willing participant in this experiment.”
Yunho waved his fingers awkwardly, the tips of his ears on fire. “Hi.”
San shyly hid behind you, putting his hands on your shoulders and keeping you between Yunho and himself. Your silly introverted boy.
“Hi, Yunho,” you offered for the both of you.
“Yunho is just as inexperienced as my species is so you will be showing him today how to get a female’s cunt lubricated before intercourse,” Seonghwa announced.
Yunho’s eyes opened wide. “Oh my god, did you have to go into that much detail?”
Seonghwa nodded sagely. “Babe and San need to know the particulars before the experiment begins.”
You turned around to peer up at San. “Still okay?” You asked him.
San’s eyebrows lifted in question back at you. “Are you?”
Fucking the aliens under the guise of them learning more about humans was one thing, a fun thing, but something entirely different than fucking another human. But it was still for the aliens, right?
You locked eyes with Seonghwa. “You’re gonna watch, right?”
Seonghwa pursed his lips and swallowed. “I will be watching and taking notes as you perform this task for us.”
You nodded resolutely. “Let’s do this for Seonghwa,” You said to San.
San smiled, slow and crooked. “For our alien boy.”
“Our?!” Seonghwa squawked before smoothing his features. “For all of us, if you would.”
Seonghwa spoke the harsh, sharp sounding language of the alien’s and a s-wave shaped table produced itself from the floor. He waved his hand towards the shape. “For you, my moo--Babe.” He pressed his lips to a flat line. “Please, lay on this, so that we may all observe.”
You walked over to the table and shed your robe. You glanced up at the corner that the aliens always seemed to talk to. Was Jongho up there? Did the table/bed come from him? You were curious about the final alien you had not met.
Once you were positioned on the table, with your lower half raised on the crest of the wave of the table, you braced your feet firmly, leaving yourself spread. This was lowkey feeling like a visit to the gyno. “Now what?”
“Yunho, you will listen to what San says in order to make sure Babe is gooey,” Seonghwa informed the other human in the room.
Yunho was scuffing his socked foot into the spotless white floor shyly. “Gooey?”
Seonghwa gave Yunho a small push forward and the taller guy stumbled towards you.
“San, help him out,” You offered.
“This is my girlfriend so you gotta give it your all, my guy,” San said, scratching the back of his head.
Yunho’s head snapped as he met San’s eyes. “What?”
San shrugged one broad shoulder. “We like it. It’s okay.”
“I’m getting cold,” You whined.
Seonghwa jerked forward and then stopped himself. “San, you should give Babe her robe.”
San, grabbed Yunho’s hand, and dragged him towards where you were waiting on the s-wave table. He dropped Yunho’s hand in order to fetch your robe and help you shrug it over your shoulders.
“Thank you, Baby,” You murmur.
San smiles. “Anything for you, Babe.”
You cupped his face for a kiss, that started out soft and thankful but San pushed his hips forward on the table to deepen the kiss and you're digging your hands into San’s hair and you both let it get away from you.
The sharp alien language cuts through the air. You break the kiss, knowing that this was not what the aliens wanted. But breaking the kiss allowed you to see Seonghwa licking his lips, looking like he desperately wanted to join in.
“To be fair, kissing also makes me gooey,” You said to the corner where you knew the other aliens were observing.
“Guess I should get to work,” San said, knocking his forehead against yours fondly.
“Have fun,” You whispered.
“Never as much as you seem to have,” San joked.
San pushed one small, final kiss to your lips and then he was moving down the table to where Yunho was still standing some feet away. San waved over the other human. “Come on, Yunho, you’re not going to make her come from over there.”
“I'm not sure…” Yunho’s eyes slipped to Seonghwa, then San, then back to yourself, walking until he was at the base of the table you were on.
“You liked helping Wooyoung, did you not?” Seonghwa prompted.
“Yes, I--yes,” Yunho nodded.
“Then you'll like this. Babe and San have a way of sucking others in.”
San laughed like he was delighted by the compliment. He stood by your hip and grabbed Yunho’s hands once again. San immediately brought Yunho's middle finger into his mouth and sucked. Yunho’s mouth was on the floor, and so was Seonghwa’s.
“My Babe likes it direct and hard.” San guided Yunho’s middle finger to press down on your clit.
“Oh my God, San,” You moaned as Yunho’s finger pressed against your clit with no warning.
“If you play around her clit, moving the hood, eventually she’ll come out to play for you,” San murmured under his breath. You could tell he was concentrating. “I like to suck on it after that, because her hips will lift up and she makes the best noises, but let’s stick to touches and not oral.”
The harsh buzzing of the alien’s natural tongue cut through the air and Seonghwa’s head whipped back towards the corner where Hongjoong and Jongho were more like observing.
Seonghwa raised a circular device with a finger hovering over it. “Hongjoong wants to know if oral is more complicated or you’re not sure the human would be good at it.”
“It’s complicated. When he graduates from beginner’s class, he can move up to oral.”
Your hips bucked upwards and you whimpered as you started to feel good from Yunho’s touches.
“San?” Yunho sounded uncertain at your response.
“That’s her sign that she wants more speed. My babe has no problem telling you what she wants but depending on the girl, she might want you to be a mind reader.”
Yunho’s touches went from a ten to a sixty and you cried out, closing your legs. San chuckled at the messy attempt of Yunho. Was he finding this cute?
San pried your legs open with next to no work. “No, Yunho, like this. My spit is probably dried by now but Babe’s probably a bit gooey for you. So you dip your finger down by her hole--” You feel the first joint of Yunho’s finger pushed into your hole and you whine. “--oh his fingers look so pretty inside of you, Babe.”
“Feel good too,” You couldn't help but grunt.
“And then back up like this…” Yunho’s finger was circling your clit, re-wetted and ready to play. “Speed up just a bit. Try another motion instead of circling it. Find what she likes. Watch her body. Babe’s super expressive too so--”
San turned around to look at your face, his crooked smile making your heart beat, Yunho behind him with a curious look on his face. As Yunho tried moving his finger back and forth across your clit with a little bit more speed, you bit down on your lower lip.
San’s grin widened and he turned back to Yunho. “See? She liked that. Tell him how much you liked that, Babe!”
“Fuck, Yunho,” You whined.
“Success!” San shouted in jubilation.
The alien’s language slices through the air and Seonghwa’s eyes remain on the floor as he relays the message. “Jongho says you should bring her to completion. We want to see a full exercise.”
“Hmmm. Well, if I know my Babe, she’s going to want something inside of her while she comes.” San sent a quick flash of a conspiratorial look over his shoulder and then settled his gaze on Seonghwa. “Yunho’s too inexperienced to try that. And I have to focus on guiding him. So…”
Seonghwa’s eyes widened. “No. I cannot.”
San pouted. “That’s too bad. The last time you fucked her, she didn’t even come. She was left feeling so needy I had to give her oral. You don’t want to make her feel unsatisfied like last time, do you Seonghwa?”
Seonghwa dragged his gaze upwards to meet yours. As you were still being stimulated by Yunho, you could only imagine what the eye contact cost Seonghwa. “Was I greedy?”
“It’s okay--oh my god Yunho--you didn’t mean--TO! FUCK!”
“It’s now or never, Seonghwa,” San tempted the alien in the room.
Seonghwa took a step forward, despite the scratchy alien language that was practically bouncing off the walls. Clearly Hongjoong was not okay with his well-conceived plans going down the drain again.
San went to your other side, moving so that Yunho could take his spot by your hip, and Seonghwa could move between your legs.
“Just put in the tip, it’ll be fine,” San assured Seonghwa.
Seonghwa blinked innocently at San. “But the tip is extremely sensitive.”
“You don’t need to fuck her, or waste any of that pretty green cum. Just be inside of her to support her.” Sometimes you were surprised by the nonsense that San spewed to encourage the aliens.
Seonghwa pulled aside his robes and you gasped audibly at the view of his cock. You had forgotten how pretty and curved he was. San put a hand on your thigh and squeezed it reassuringly. If anyone was on your side, it was your boyfriend.
Seonghwa moaned loudly as he pushed his cock inside your hole that was clenching down. Yunho frowned visibly. “What do I do if I can’t get any wetness from her hole?”
“Spit,” San supplied simply.
Yunho looked worried. “I don’t think…”
“She’ll love it, don’t worry,” San winked across your body at Yunho.
Yunho spat on your pussy and continued to move his finger back and forth on your clit. Seonghwa’s hips moved at the sight of Yunho spitting on your cunt. Your hips moved in response, pulling Seonghwa further inside of you.
“I don't think this was a good idea,” Seonghwa said through clenched teeth.
“I'm--close,” You whimpered.
“Don't stop, Yunho, keep going!” San encouraged him. “Don't change a thing or you'll have to start all over again.”
Seonghwa’s ‘just the tip’ was starting to become halfway in. Tiny jerks of his hips, unable to resist how warm and wet you were, were the culprit. His hands clenched down on your hips and he began to thrust himself into you.
The cacophony of noises would have been distracting if not for the dual sensation of Seonghwa inside of you and Yunho’s messy touches on your clit. San with his encouragement towards Yunho, Yunho wondering if he was still doing okay, and Seonghwa babbling about how good your pussy was, as per his first experience.
You came, and came hard. You closed your eyes and threw your head back, locking your legs around Seonghwa. Your pussy walls clenching around Seonghwa sent him over the edge, and with a cry, he also came inside of you. San was so busy drinking in the dual climaxes that he forgot to tell Yunho to stop, so the other human sent you into overstimulation mode.
San snatched Yunho’s hand away after hearing your cries of pain and shook his head, quietly informing Yunho that he had gone too far. Yunho’s ears were more red than a lobsters, but he abashedly apologized to you.
Seonghwa was a panting mess. Of course, the cherry on top was when the alien pulled out and his glorious cum spilled out of you. All three males watched with sharp interest.
“Do we…have to…stare?” You demanded.
“Yes,” They all responded in unison.
Confirming once again that despite the species, a male was a male.
A sharp, buzz of the alien language snapped Seonghwa out of his post-orgasm bliss. A cube floated near his arm and he snatched it, capturing his come in the container.
“Might as well make this useful,” He mumbled under his breath.
“Hwa, wait--!” You gathered your robe around you and moved to the edge of the table. You winced when you brought your legs together.
“Are you okay?” Yunho wondered, putting a hand on your shoulder.
San chuckled. “That’s what she gets for wanting it hard and quick immediately.”
You sent Yunho what you hoped was a comforting smile but still quickly moved to make sure Seonghwa did not leave the room before you talked to him.
Seonghwa’s face was collected but his eyes spoke a thousand different words. “My moon?” He said successfully, despite cutting himself off several times today.
“I don't know what they told you. Or what they did to you. But a lot of people have sex and form attachments. I don't want you to feel weird or bad about it.”
You looked back at San, who was teasing and joking with Yunho. “San and I started that way. But we couldn't keep it to just sex. It's always been more than that to us. And it can be more than that for you too.”
“But the mission--”
“Seonghwa.” Did aliens have hearts? “I think you should take in consideration how you feel. Us humans have a saying. Follow your heart. It means follow how you feel versus what's logical.”
Seonghwa chewed on his lower lip. He jumped a foot in the air when the alien language snapped between you two. He nodded his head. “I'll consider it.”
The alien moved to leave, lifting his hand to summon Yunho. Hongjoong must want a debriefing.
“Also, Hwa?”
The alien cocked his head cutely in response. You cupped the side of his head and pressed your lips against his. “I'll miss you.”
Seonghwa got a goofy, lopsided smile on his face. “I'll miss you too, my Moon.”
“Bye,” Yunho said shyly, ducking his head and dashing after Seonghwa.
San opened his arms and you barreled right into his chest. San hugged you so tightly that you couldn't breathe. You had to tap on his pec to get him to loosen his arms. San giggled brightly.
“Someone enjoyed themselves,” You couldn't help but smile back up at San.
“I think we’ve found our place in life,” San proclaimed.
“What, being sex coaches to an alien race?” You laughed.
“Mmm,” San hummed in agreement. “And receptacles.”
You shuddered at the word. Seonghwa’s cum was still dripping down your thighs as you spoke.
“I hope Hwa doesn’t get scolded too harshly by Hongjoong,” You murmured.
San’s sharp eyes raised until he looked in the corner where the Alien’s observing hub must be. “I’ll give them a piece of my mind if they make him look even more like a kicked puppy.”
“You just want them to punish you with the ropes again,” You teased your boyfriend.
San shrugged his shoulders, smiling just as brightly as his laugh. “Gotta get my kicks somehow since my girlfriend is too busy being a hole for aliens.”
“San!” You guffawed, slapping his chest.
San placed a sweet kiss on your cheek, making a loud raspberry as he did so. “I love you.”
“I love you too, Baby.”
