The humans woke up when morning came. They were confused when they found themselves on the couches
in incredibly uncomfortable sleeping positions but were soon informed by Jimin what had happened, confusing everyone even more.

"So they just left?", Hoseok asked, eyebrows almost disappearing into his hair. The kitsune nodded, a big yawn leaving his lips after explaining the whole thing. His eyes were drooping and the others soon realized they should keep their questions until after he had a good rest.

Jimin refused, not wanting to give into the very tempting thought of sleeping, "Jungook and Taehyung are sleeping upstairs-"

"Yeah yeah go to sleep Jimin, you're exhausted", Yoongi complained, pushing the kitsune back onto the couch, "We'll let them sleep as well. I have a feeling they need it after yesterday".

Hoseok and Namjoon had already disappeared into the basement, wanting to perfect the cure. They were so close to saving the world and they absolutely didn't want anything to go wrong in this last stage. If everything went alright, they would soon be ready to test their cure on actual mutants.

Jungkook groaned, his mind still in a haze as he felt the person in his arms shift. Taehyung cuddled closer, wiggling his body deeper into the warm hold. "Baby", the werewolf grunted when he felt a rush of arousal go through his body. He couldn't help but let out a soft growl next to the boy's ear.

Taehyung stopped his movements, now wide awake and frozen, unaware of what he had started. The boy let out a deep sigh when Jungkook started pressing soft kisses along his neck. "Jungkook-", he choked out. He brought up his hand to slide it up Jungkook's jaw, his back still pressed against the werewolf's strong chest.

When Taehyung felt the kisses cease, he decided to be brave and clamber out of his mate's hold. Jungkook let a whimper escape his lips, his large palms gripping the other's waist as Taehyung was laying above him, on his knees, pressed to his chest as they kissed messily. His mate was ruthless, having never experienced such things before, his legs still so fairly new to him that he sometimes hit Jungkook with them due to excitement.

They kissed like there was no tomorrow, hands roaming around each other's bodies, Taehyung being careful to not touch Jungkook's still healing wounds. From time to time they broke apart, staring at each other with red lips and doe eyes, smiles playing on both of their faces.

"You're so cute", the alpha said, his palms tracing Taehyung's skin under his shirt. His mate smiled, leaning down to kiss Jungkook again. "I know".

Jungkook moved then, turning them around, Taehyung's right leg hitting his leg when the other fell on the mattress giggling.

Their lips clashed again, Jungkook's body catching fire even more when Taehyung circled his still wobbly legs around his waist, his fingers tracing his already shirtless back. He moved lower, licking over the bite mark on his mate's neck, both of them feeling the oversensitivity that came with it, Jungkook's wolf howling in joy for finally being able to be with his mate.

Taehyung looked just as blissed, sparkling eyes staring at Jungkook from under his long lashes like he was everything he wanted on that planet. Jungkook hoped that was true, pulling apart so he could admire his mate, laying astonishingly under him, his shirt almost falling off his shoulders from how skinny he was. Jungkook worked his fingers softly, unbuttoning it as Taehyung chuckled when he tickled his skin teasingly.

"You're being so slow", Taehyung spoke, squirming when Jungkook slowed down even more. Jungkook chuckled, pressing a kiss on Taehyung's lips before pulling him up in order to get the shirt off him, his skin on display under his body.

His mate was only wearing a pair of boxers his brother's given him, his long, tanned legs on full show for only him to see. Taehyung in his human form was as beautiful as the merman side of him, his legs being as pretty as his tail used to be, his skin being still as smooth and sparkling as the scales he had.

"God, you're so pretty", Jungkook mumbled, still not being able to comprehend the beauty that was Taehyung. "Quit dawdling and kiss me again", Taehyung spoke, clicking his tongue. Jungkook raised an eyebrow at that, quite liking the bossy side of his mate. His cupped his cheeks, pulling him into a kiss, smiling as their lips crashed.

Afterwards they kept kissing softly, Jungkook making sure he marked more patches of his lover's skin, leaving soft bite marks on his neck and shoulders, where they could be easily seen by everyone. He still made sure they didn't hurt as much as the mate mark, never forgetting to press kisses against that too.

When Jungkook felt too hot for his own liking, he looked lower, realizing that Taehyung, for the first time in his life, had a hard on. The former merman has been already whimpering softly for a few minutes, body thrashing around the sheets in an unknowing matter since he didn't know what was happening.

"You're aroused Taehyung, that's totally normal", the alpha said, his hand cupping Taehyung's shoulder, fingers moving slowly towards the are that needed to be touched. Taehyung's eyes stood confused, wanting to say something but Jungkook quickly shushed him, "It's okay. Let me take care of you".

Taehyung arched his back when Jungkook barely touched the material of the boxers, his oversensitivity coming from the fact that it was his first sexual experience ever.

Whimpering, Taehyung looked at him with doe eyes, making Jungkook smile softly. His wolf was rushing with hot blood inside him, but he wasn't going to give in. He has to make sure his mate was feeling good, that Taehyung was safe and that he didn't hurt him.

Thinking of Taehyung again, Jungkook pulled the boxers off him, watching slowly as his mate's swollen shaft came into view, already being slick enough for him to touch.

When he did touch him, Taehyung moaned, loudly, and Jungkook was fairly sure that the whole house was able to hear him. He just hoped no one was going to come to their room since his wolf was barely under any control, any person that could've seen Taehyung like this already being dead in his eyes.

"Are you alright?", Jungkook murmured as he pressed kisses against the tan skin of his mate.

Instead of answering, Taehyung let out more whimpers, moving his legs in an attempt to do something, to understand what was happening to him. Jungkook smiled lovingly, moving his hand, starting slow, before he leaned back in to capture the other's lips in a soft kiss.

"You're so adorable", he murmured, their hots breaths merging as he kept jerking his hand faster, Taehyung looking at him with a blissed expression.

Jungkook knew his mate wasn't going to last, stopping when he felt the other coming close to his climax, looking at him with wondering eyes. "Are you sure you want this?"

"I don't know what exactly I'm feeling
Jungkook but I just want to experience this with you".

Smiling, the alpha pulled away in order to get rid of his pants and boxers, looking at Taehyung with loving eyes, admiring every patch of his tanned skin and his soft, red, messy hair, the same color
covering his face and body.

Jungkook gave himself a few strokes, trying to lubricate his hand so he could at least prepare his mate for the upcoming slightly painful experience. Leaning over Taehyung, he caressed the former merman's thighs with soft touches. "God I love your legs. Can you open them for me?".

Jungkook pushed Taehyung's legs up, bending them and then making enough space for him to be able to fit between them. Taehyung raises his head, looking curiously at him. "What are you doing?", his mate asked, Jungkook smiling softly before petting his thigh.

"I will have to prep you so what comes next won't hurt, okay, baby? Do you trust me?" Jungkook whispered, his arms caressing Taehyung's legs softly.

His mate nodded, letting his head fall back on the bed with a pleased sigh as Jungkook made sure to be as gentle as he could be, tracing his fingers over the soft skin, pressing kisses on his knees before lowering enough to hear whimpers coming from Taehyung.

When he reached the other's hole, his fingers still wet with his own precum, he circled one around it, making sure Taehyung understood what was happening.

His mate jerked, his leg kicking Jungkook in the arm, both of them chuckling at the action. When he pressed his finger in, a whimper of pain fell out of his mate's lips, Jungkook bending enough so he could kiss Taehyung to assure him that everything was going to be fine, that he was there.

After prepping him enough, Taehyung almost coming only from Jungkook's fingers stimulating him, the alpha decided his mate was ready, coming closer and giving his aching shaft a few strokes before aligning himself. He looked at Taehyung, both of them making eye contact, then leaned in, pressing his free arm next to his body.

"This might sting a little".

Jungkook lowered his head, tracing his lips over Taehyung's as he entered his mate, both males groaning in pleasure as their bodies finally became one. The wolf inside the alpha started howling loudly, heat taking over his body as the need to mark Taehyung as his became greater.

He kissed over his jawline, hearing the other moan when he started thrusting slowly, then buried his nose next to the bite mark, inhaling softly before biting it again, not as a mating mark, just purely out of love and comfort.

Taehyung circled his arms around his shoulders, pulling him closer, and Jungkook groaned in pleasure when the other unconsciously tightened around him for a few seconds.

His thrusts became more erratic, the alpha already knowing neither him or Taehyung were going to last since this was their first time and the oversensitivity of the mate mark was intensifying every emotion and feeling.

Taehyung was a moaning mess, arching his back while digging his nails in Jungkook's skin, trying to avoid the bruises that were slowly fading but neither cared about them anyway.

Jungkook felt the moment his mate was close through the link, pulling apart only to be able to watch his face, one hand coming up to caress his reddened cheek. "I love you so much", the werewolf grunted, pressing another kiss to the boy's face.

He then moved his arm between them, cupping Taehyung's dick between his fingers, jerking his wrist fast in order to help his mate reach his first climax ever.

When Taehyung came, white liquid falling all over his belly and on Jungkook's abs, the alpha felt himself reach his climax just because of the sight and of the amount of emotions the link was bringing him, all from Taehyung.

The merman was panting heavily, his body shivering as his eyes searched Jungkook's, refusing to let them close just so he could watch his mate's furrowed face, jawline tightened as he kept thrusting, chasing his climax.

"Tae- fuck I'm going to-"

Jungkook let his head fall on Taehyung's shoulder, biting over the mating mark as he felt himself coming in waves, his climax being more intense than Taehyung's due to his nature. Taehyung was caressing his back, legs already tangled around his body, both of them panting heavily as they tried to come down from their highs.

"I love you Jungkook".

The werewolf grinned widely, his chest still heaving, "I love you too Taehyung".
