Like an Echo [KTH Fanfic]

Warmth

Warning: Short chapter ahead but it's nsfw. Nothing awfully graphic, but we learn something new about soulmates.
Sorry for the short chapter, I'll try to post another chapter quickly. I've been writing a lot lately and getting more chapters out quicker than usual, so I hope these don't suck.

"Tae," Lena whined as he got off of the bed.

"I'm just going to get some lotion, princess," Taehyung cooed. "I'll be right back."

It was the night after Opal and Jimin's wedding. Lena had teased Taehyung during the reception, but she didn't get the usual reaction from him. Instead, Lena ended up fully surrendering, watching Taehyung's dominate nature bloom before her. She had seen it before but never to the extent it went to last night.

Lena's thighs were littered with bruises, her bottom the same. Her chest ached from being tugged and sucked on. She was tired.

Regardless of what had happened, Lena was still craving him. Her emotions heightened, her neediness growing by the second.

"Tae," her lips quivered. "Tae, come b-back."

Taehyung felt her emotions seep into him and heard her calling, making him rush back to her with a bottle of lotion in hand.

"Oh, bug, I'm so sorry," he said as he pulled her into his arms. "I shouldn't have been so hard on you, I'm sorry, I didn't mean to make you drop."

"I h-haven't dropped," she hiccuped. "I don't know what's happening, but I need you inside of me again."

His eyes shifted, but he remained weary of what was happening.

Lena pulled herself up and back down onto his member, sighing in content.

"Just needed to be closer," she hummed as her chest and stomach blossomed with content.

"Are you just going to warm?" He asked, his eyes lightening a bit. "Is that it?"

Lena nodded, her hips wiggling to settle down properly.

"Why do you think this is?" Taehyung asked.

"I don't know," she said. "I'm sorry if this isn't comfortable."

"It's fine, princess," he said. "It's actually perfect."

Soon, Lena fell asleep like this, her heart fluttering.

Taehyung, unable to shake the weird feeling, grabbed his phone and texted Jin.

Taehyung:
Hyung, are you awake?

Seokjin:
Yeah, Sephi can't sleep so we're watching Gilmore Girls.
What's wrong? It's really early.

Taehyung:
Has Sephi ever...warmed you?
But got super emotional first?

Seokjin:
Plenty of times.
It's some weird bonding thing when a soulmate is at the peak of their ovulation or pregnant.
Why?

Taehyung:
Well Lena just did it and it's never happened before.

Seokjin:
It's a miracle that you two have never done it during that part of her cycle.
Unless she's pregnant?

Taehyung:
I don't think she is.
I felt her last period, it was last week

Seokjin:
Then she's definitely ovulating
Plus, if she were to be pregnant, different instincts would kick in for her and you as well.
Have you never been taught the full mating ritual?

Taehyung:
There's a mating ritual?
I've never heard of anything other than sex, hyung

Seokjin:
Probably because it is just sex
But it's intimate and strange, it usually just stays between soulmates.
When your soulmate is pregnant, they will have heightened emotions, including sexual ones.
Once the first trimester has passed, the thing you described will happen, except you'll feel the desperate need to have her too.
It'll start as warming and morph into a breeding session essentially.
It isn't scientifically necessary for it to happen, and sometimes it just doesn't
But I had it with Sephi and it was euphoric and beautiful.
It's so intimate

Taehyung:
Well thank you for sharing, hyung
I guess I need to go
She's asleep and I should be too

Seokjin:
Goodnight and enjoy that
That's always been my favorite time with Sephi
Shit she can feel that I said that
I guess I'll be busy too

Taehyung laughed before he switched off his phone, glancing at Lena.  She was perfect. She was his. He was hers. It was such a special moment. There was nothing sexual about it at the moment, it was merely a beautiful connection.

The night the two had was considerably less innocent, so this felt like a recharge. Being so close let their bodies heal and let them rest.

Both of them would learn to adore this time together and Taehyung would go out of his way to schedule time during tour to be like this with her.

They both slowly learned why it was rarely talked about. No words could describe the bonding feeling of these occurrences. It would only be topped by what would happen during pregnancy.

For now, the two soaked in each other, being fused until morning.
