I imagine Ren shows his possessive side only to those he admires. He wants the person he looks up to all to himself. Once he finally has that person in his sights he gets to know them better, forming a deep connection with them. Mysta is perfect for this....

They finally meet and Ren gets to know Mysta better. He follows him a lot too, always popping up in his streams and going where he goes. Mysta finds it a bit strange but he just thinks it's nice that his kouhai likes him so much. That is, until he starts popping up in his chats more and more. They're getting a lot closer friendship wise but Mysta senses that Ren is taking a special interest in him. Ren finally gets to meet with him in an offcollab and they hang out for a day or two. Ren is very, very friendly during this time and Mysta begins to relax and forget about any suspicions he had about Ren, not realizing his smug face every time this cute and innocent fox lets down his guard more and more. They decide to stream their offcollab and Ren still has that same smug look on his face, and Mysta just takes it as excitement for the upcoming stream. The moment he hits the stream button, he smells something sweet....

They both talk to the chat as normal, discussing what they did in the past few days, the places they went to, the sights they saw. Mysta tries to ignore the sweet scent, for he thought it was just coming from one of the quirky souvenirs they bought. However, it starts to get stronger as time goes on, and now Mysta is starting to feel dizzy. Ren is chatting like normal, keeping the viewers entertained while Mysta's usual momentum with keeping up is starting to decline. He starts sweating and finally asks Ren "what's that smell?" to which he answers "must be one of the teas we bought".

Mysta's dizziness starts to get worse, and now he's starting to sweat. Ren notices and pats his back. "Hey, you okay there Mysta?" He doesn't want to end stream, and he knows that anyone who knows him understands that he'd never want to end stream even when he feels off, so he replies "yeah, I'm fine." But now, inhaling this strange sweet smell is starting to get to his head to the point where he can't finish sentences and the objects around him start to appear blurry. Ren starts to rubs his back now in an attempt to ease whatever discomfort he may be feeling, but now he feels even more dizzy as he looks Ren in his opalescent, beautiful, otherworldy blue eyes. Mysta gets lost in his eyes and reassuring words, and has now ceased forming words at all.

"Okay guys, I think we should end stream here. Looks like Mysta's not feeling too well, I'll take him to bed to get in a nice nap. I'll see ya later, chat! Thanks for coming!" says Ren cheerfully as he switches to the ending screen and then ends stream after barely a minute of the graphics changing. As Mysta begins to teeter from the scent becoming overwhelming for him now, Ren catches him in his arms and princess carries him to the bedroom of their airbnb. Mysta cannot form any words at all by this point. All he can do is stare into Ren's ocean eyes, not noticing the very apparent bump getting bigger in his pants....

Ren lays Mysta on the bed gently, taking extra care to rest his head comfortably on the pillow. Laying down like this Mysta feels a bit vulnerable, and Ren rubbing his back earlier felt so comforting. "I'll let you get some rest now. Call me if you need me," Ren says as he gently kisses Mysta's forehead and starts to get up from the bed. Mysta may not be able to form many words, but the feel of that kiss made his heart flutter. He couldn't let him go, not after Ren left him with that feeling. Mysta starts to breathe a bit more heavily now and quickly grabs Ren's sleeve. "Wait," he says. "D-don't go. I...uhm....I need you here." Ren's face is turned away but he has on a rather sinister smile, and Mysta is still too dizzy to even notice the bulge in Ren's pants....

"Oh. All right, if you say so," says Ren. He moves back towards Mysta, the sweet smell getting stronger. "I....I don't know how to explain this," says Mysta. "but....I uh...umm... I really....feel weird around you.....like I want you to uh....stay...um....with me..." Ren kisses Mysta's forehead again, which is now starting to form tiny beads of sweat. "Sure, Mysta. Anything for you. You'll still need some rest though. Here, let me help you get out of those clothes. You're starting to sweat. Is that okay?" Mysta nods slowly, still completely lost in Ren's iridescent ultramarine eyes.

Ren starts with his gloves. Instead of lifting them off finger by finger, Ren gently slips his fingers under one of the gloves while Mysta's hands are relaxed, palms facing the ceiling. Ren doesn't want to stress Mysta out by being too aggressive, so he very gently gets under the front of the right glove, slowly sliding it off bit by bit. Ren needs to reach over Mysta to get the glove all the way off, and Ren's head is mere centimeters away from the sweat pooling around Mysta's nose. Combined with how close this alien's head is to his face, the unintentional sensual feeling arising from having his glove slipped off as if it's a delicate piece of lingerie, all with the sweet smell still filling his nose and getting him flushed, Mysta's heart starts to race even faster and his brain starts to fill with irrational thoughts.

"Ren....I....." Mysta says, nearly whimpering at this point. "Hm?" says Ren.

"Please..." whispers Mysta as he tries to lift his head to Ren's left ear, right hand still locked below Ren's, which is about 1/3rd the size of Mysta's.

"Kiss me....."

Ren now has on that same smug and sinister smile from earlier, and as he lifts his head to look into Mysta's dazzling blue eyes, he whispers back to him.

"Yeah, of course."

Ren smiles at just how much control he now has over Mysta, having him panting and sweating under him while barely making a move on him yet. The sweet smell is now getting more pungent, and it's starting to fill Mysta's head with even more lewd thoughts. He tries to suppress these thoughts, but looking deep into Ren's eyes makes it difficult to think about anything else. His mind is full of nothing but this strange alien boy now, and he unconsciously moves closer toward his soft, smooth lips. Ren meets his head and goes in for a gentle yet long kiss. He lifts up for a second to look at Mysta's cute and flustered face, then goes back down for another kiss, switching between licking Mysta's top lip and pressing both lips to his. Mysta starts getting more into it at this point, despite having no experience with kissing at all. Ren senses this and now makes a move to get his hands under the fox detective's left glove. He begins to kiss him more passionately as he slowly gets a knee up on the bed to balance out slipping under both gloves simultaneously. Mysta starts to feel a stronger sensation of being vulnerable, what with his delicate palms now exposed and being tickled by Ren's gentle touch combined with his loving and gentle kisses, it finally leads to his mind being driven positively wild with lust.

"Ahn...R-Ren...." Mysta whimpers. "I.....um.....I...I..."

"What?" says Ren with a slightly sly smile. "Do you want something from me?" He slips off both gloves and starts to move the knee he has on the bed under Mysta's leg. "Tell me what you want, Mysta. You can tell me anything," he says as he begins to move closer to his face again.

"Please.....touch me...." mewls the now completely vulnerable and almost desperate Mysta. "Touch me....more....."

"Gladly," says Ren with an almost mischievous tone.

Ren slides both his large hands slowly down Mysta's arms and makes his way to the collar of Mysta's shirt. He begins to unbutton it while continuing to kiss him, now trying to insert his unusually long and thin tongue into Mysta's mouth. Mysta is getting even more turned on now and allows Ren to enter his mouth. Ren can barely hold back at this point and nearly goes down Mysta's throat, causing the foxy sleuth to let out a small moan.

Ren fully unbuttons Mysta's shirt and starts to make his way down his neck and chest, all the while unbuttoning his own shirt. Ren is now salivating all over Mysta's skin after finally getting to taste his sweat, for he has always wanted to revel in the flavor of human perspiration. He didn't know how good it would taste until he finally got the chance himself to lick it straight from the source. This is unlike anything he's ever had the pleasure of tasting back on his planet, human sweat is completely different. He needs more of this delicious flavor, so he proceeds to make his way to Mysta's nipples, curling his long black-blue tongue around the soft, tender area. That's when Mysta lets out another moan and slowly starts to open his legs.

"Do you feel good, Mysta?" says Ren as he looks up from his position at Mysta's flustered face. "You sure you want me to keep going?"

"M....m-hmm...." says Mysta, trying to muffle his now broken voice that sounds almost like a kitten mewling for the feeling of warmth.

"Heh," snickers Ren while now getting fully on top of Mysta. "All right. But after this....." he says while lifting his under shirt over his head and horns, tossing it to the side of the bed. "You'll be all mine."

After tossing his undershirt off to the side, Ren goes back down to make out with Mysta. Now he is further onto the bed and pressing his cold body close to Mysta's after pulling his orange shirt down his arms. The cold sensation of Ren's torso makes Mysta whimper, turning him on even more. Ren is now between Mysta's legs and can feel the small bulge against his crotch through his tight white pants. Ren starts grinding against Mysta, making him moan even more now before their pants are even off. Ren reaches down and starts unbuckling his trousers. Mysta reaches down as well, desperate to get his pants off faster, but then hesitates out of shyness. Instead, his hands wrap around Ren's back as he kisses him more passionately, now inserting his tongue into the alien's. Ren now tries to undo Mysta's pants. He manages to get the belt off, but has trouble with figuring out how to get his white pants down. He comes across a zipper on the side, pulls it down, and the pants slide off easily, revealing his small black underwear. Ren slips off his own pants and reveals his tight, dark grey boxer briefs with a large dark spot in the middle.

"R-ren..umm..." stutters Mysta.

"Yeah?" responds Ren, eager to do whatever Mysta asks.

"I don't know much about your species so.....uhmm....what are you like.....down there?"

"Heh...", smirks Ren. "Why don't you find out for yourself?" he says as he looks at Mysta's cute, innocent face and guides his hand down Ren's tight abs and into his boxer briefs. "It's okay, I know humans can handle it."

Mysta gasps at how different Ren feels down there compared to a human. It is completely wet and sticky all over, and definitely bigger than the average human penis. He saw a bit of a black trail leading almost from his navel down to his loin. He thought it was pubic hair at first but after getting a closer look, he notices that there are small black spots surrounding the trail that seems to be a part of his skin. His boxer briefs are still on, but Mysta can already see that he is nearly soaked through the underwear. He is a bit hesitant to keep rubbing the extraterrestrial, for the ridges, texture, and color of Ren's penis are so strange. However, Ren keeps Mysta calm by guiding his hand to different places of his anatomy. This helps calm Mysta down by getting him used to Ren's strange body. It's cold to the touch, but it feels good against his skin on such a hot day. It takes a while for Mysta to get used to the slimy fluid that Ren is secreeting from his phallic member, but he becomes fascinated by all the different parts that are coiled under what appears to feel like his testicles. The sticky fluid coating Ren's lower area seems to be some sort of lubricant, and Ren notices that Mysta is a bit put off by it, so he takes his hand out from his dark gray underwear and carries it up to his mouth, licking it slowly and intertwining his tongue with Mysta's fingers while staring into his beautiful blue eyes.

"I know I'm very different down there," says Ren in a quiet voice while still licking. "There was only so much my disguise could cover. And I'm not sure it can cover what else may be revealed, so I'll try to hold back a bit."

Ren removes Mysta's hand from his mouth and slowly takes it down to into Mysta's tight and small black underwear along with his own hand. "You're pretty wet down there too," Ren says as he pulls down Mysta's underwear below his knees to fully reveal his cute erection.

"Hnnh! Ahh! Ren, what...." stutters Mysta as he feels a tingling sensation on his erection. "What is this feeling? Is this even safe for humans? Or something?"

"It's okay," responds Ren. "It's just a special discharge that males in my species secrete to help with sex. It'll feel good soon enough."

Ren continues rubbing Mysta and moves onto his hole. He casually inserts one finger and notices how comfortable Mysta is getting now. He's already taking it very well, so he proceeds to insert another finger into him, to which the fox boy yelps and closes his eyes. Mysta is really getting into it now and starts moving his hips and moaning along with Ren's rhythm. Ren is just watching from above, getting more wet in preparation to enter Mysta's soft and willing hole. "You're so fucking hot, Mysta. Seeing you squirm under me like this when I haven't even intered you yet...." says Ren in a very sultry voice. "....it's turning me on so damn much.

Despite being a completely different species, one can easily recognize how full of lust Ren's otherworldly blue eyes are.

"I can't hold back anymore. I need you now."

Ren takes his fingers out of Mysta and grabs his thighs to pull him closer. Ren now rubs his wet, sticky bulge just against the top of Mysta's entrance. The ridges on top of it feel nice against him, and Mysta starts to calm his worries about how he'll handle Ren's anatomy as Ren rests his cool torso against his.

"Mysta," says Ren in a very breathy voice right next to Mysta's ear while still grinding against his ass, now reaching the limit of how turned on he could be before he can't control himself anymore. "Don't be too alarmed...at how I look down there..."

Mysta is confused at what he meant until he felt movement down in Ren's lower region. Ren lifted his hips up a bit from Mysta's bottom and a thick, tentacle like appendage unfurled from under his testicles. The appendage seemed to inflate as it unfurled itself, to which Ren let out a breathy moan of relief, revealing a very thick black shaft with small ridges and nubs on it. It almost seemed to glow in certain parts, but Mysta's mind was too dizzy to try to figure it out. The only thing he could see was the appendage between Ren's legs moving in a way a normal penis shouldn't, and it was snaking up Mytsa's shaft while Ren moved back up toward his face. Ren looked into Mysta's eyes and started making out with him again, grinding his now lengthened penis against Mysta's perineum and balls, and wrapped his big strong arms around Mysta's delicate, thin torso. The lubricant coming from Ren was trickling down to Mysta's hole, and the tip of Ren's strange alien cock started to massage his entrance, preparing to insert itself into him. Mysta whimpered and tightened up a bit at feeling the cold phallus trying to penetrate him, but Ren squeezed Mysta tighter and pushed the fox's thighs up with his own by bending his knees toward him, making Mysta open up and giving Ren a chance to squeeze into his tight hole easier.

"Ahn....Ren you're so....c-cold," Mysta whined. "It feels nice, but......"

"It's all right," Ren reassures Mysta. "I'll make you feel really good."

Ren moves from Mysta's mouth down to his chin and starts licking around his neck, snaking his long blue-black tongue around the middle. Ren almost bites down but takes extra care to be gentle, for he is very aware of how sharp his fangs are compared to humans.

"Are you ready for me?," asks Ren as he gets close to Mysta's left ear. "I want you to be mine, and not think of anyone else but me."

Those words made Mysta's heart quiver, and at that point he couldn't let out anything else but moans. Ren took that as a yes, immediately pressing his azure alien tip against Mysta's hole. With the secretion all around Mysta's bottom, Ren was able to slip in quite easily despite his size and how tight Mysta was.

"Ahhh....AHHH REN!!" howled Mysta as he felt the wriggling of Ren's phallus undulating deeper inside his ass.

"I've got you," said Ren softly in Mysta's ear. "I won't let you go."

Ren continued to squeeze Mysta and held him from his lower back, pushing Mysta's arms up over Ren's broad shoulders and causing his hands to dangle down Ren's strong back. "I'm going to move now." said Ren, continuing to swirl his long icy tonuge around different parts of Mysta's neck. "I'm not all the way in yet."

"O-okay..." whimpered Mysta.

Ren thrusts gently into Mysta, letting out small grunts and moans because of how tight he feels around Ren's cock. The contrast of his body temperature compared to Ren's is a sensation he's never felt before, and it's turning him on more and more the deeper he goes inside Mysta.

"Ahh....Ren....Ren!! Hahh....nhhh....Ren," moans Mysta as he grabs at Ren's back, not knowing what to do with himself as he is overcome with pleasure throughout his body. "Ren how- ah....are you......so big......hahh..."

"Sorry, am I hurting you?" asks Ren, barely able to stop himself from going deeper. Mysta shakes his head. "I'm almost all the way in."

Mysta's head is still dizzy from the sweet smell, the lust he feels for Ren, and perhaps even a side effect that may have come from being in contact with Ren's secretion. All he can feel is Ren's extraterrestrial phallus being pushed inside him and the cold feeling of Ren's heavy body against his. "It's in now," says Ren. "I'm gonna move now. I'm all the way inside." Mysta tries to respond but all he can do is clench tight around Ren's dick, eager to feel more of him. Ren starts moving back and forth now, moaning in Mysta's ear at finally being able to make love to the man who was the subject of his affection for so long. Ren softly bites down on Mysta's neck and starts sucking on it, resulting in Mysta throwing his head back and hissing in pleasure. The sensation of him sucking his neck and pushing back and forth inside him makes him unable to hold back his voice. They're getting stronger and stronger and Mysta's hands are trying to find a comfortable place to grab onto. Mysta starts clawing at Ren's back as he's feeling him more and more, getting closer to Ren's ear and neck and moaning into it passionately. Mysta's erection was rubbing against Ren's stomach as he thrusted, heightening the sensations throughout his body and causing him to grab more parts of Ren's chilly body to contain the feelings. He grabbed one of Ren's horns, to which Ren let out a strong hiss of pleasure.

"HSSSSSSH AHHN!!!," snarled Ren. "Aghhnnnn....hnnghhhh......."

"Ahh...wh-what's- ahn....wrong, Ren?" asked Mysta between moans.

"Those are....very sensitive. And touching them a certain way triggers some....bodily changes. I don't think you're ready to handle that just yet." says Ren while continuing to thrust inside Mysta. Mysta felt the size and possibly the shape of Ren's penis change when he touched his horns. He also thought he saw a part of Ren's shoulders and back change color a bit, but he was too dizzy from the pleasure of sex to really make out what it was.

Mysta's hands moved down to Ren's back and started to scratch at it, the passion of their intercourse getting stronger as Ren held Mysta more tightly. They're both moaning loudly almost in each other's ears at this point, and the scratching makes Ren thrust even faster. As Mysta's moans get even more high pitched and wild he loses control of where his hands are grabbing, switching between Ren's back and head. Ren's left hand makes it's way up Mysta's body and intertwines his fingers with the detective's, but the other hand is still trying to grab at something, and Ren is using his right arm to hold Mysta's body. Mysta grabs one of his horns again, this time getting a few fingers between the spike-like parts sticking out from it. Ren lets out another strong hiss of pleasure at Mysta touching such a sensitive spot.

"HNNGHHH AHHH, MYSTA!!!" shouts Ren, burying his teeth into Mysta's neck to try and contain himself. He can't hold himself back anymore and starts thrusting faster. Just when Mysta thought Ren couldn't get any bigger, his phallus grows even larger inside him and hits his prostate at the perfect angle, making Mysta roll his eyes back and go completely limp at the overwhelming pleasure he feels, completely missing out on seeing strange, small extremities grow out of Ren's back.

"Mysta.....y-you shouldn't have done that," whimpers Ren, now sounding like he's about to whine because the pleasure he is feeling may be overwhelming for him too now. "I.....I think I'm about to....r-realease....aahhhhh!!"

The only way Mysta can respond is through loud moans. Ren lets go of Mysta's hand and grabs both of his thick thighs, pushing them back almost against the bed and pumping as deep as he can inside him, releasing a very thick goo that flows all throughout Mysta's insides. Mysta cums as well after having his prostate hit in such a perfect spot so many times and scratches Ren's back extra hard at the overwhelming bliss and satisfaction he feels at releasing and letting out one final sensual wail.
