Their lips only parted for a fraction of a second before meeting again. Jungkook felt the victory in feeling Taehyung's low moan, bellowing into his panting mouth. The older male had followed eagerly with Jungkook's lead, especially after seeing the end result.
Taehyung's warmth brought a smile to Jungkook's lips. He had a feeling he'd be smiling all throughout this session. This was them, after all. While physical desire screamed through their bodies, it was always something that stemmed from their emotional needs.
Making each other happy, came first in this. Jungkook could easily feel it as he felt Taehyung's lips upturning to chastely brush against and linger over Jungkook's. Even their smiles seemed to want to make love, and something about that was everything.
Jungkook had been intimated, to say the least, especially with a willing desire to take a more receptive role. Yet, here in Taehyung's arms and with the other's warmth on top of him, he hadn't felt more sure. This was right, and true and perfect.
Jungkook's cheeks were hurting. Whether this was due to the flow of blood, staining them, or the smile they were forced to hold up, well he couldn't be sure. His smile grew into the kiss and widened. It almost parted their lips with how it spread. Taehyung moved with him to meet the motions.
Taehyung's breath was tingling in his lips. Jungkook's eyes, used to falling shut under these circumstances, fluttered open.
He felt his heart fluttering wildly. Taehyung had to back up, just enough for their lips to part so he could let out a soft bit of laughter. The laughter continued on, and while Jungkook hadn't quite understood it then, he felt a tingling sensation inside as Taehyung collapsed on top of him.
His beloved laid his head against Jungkook's chest, his laughter was finally expelling. The younger male pressed a kiss to the top of Taehyung's head. 
"You're too cute" Taehyung teased his boyfriend gently. 
Jungkook's lips formed into a pout and he knew he was blushing hard. Far too gone, Jungkook stuck his tongue out and moved his hands to comb through Taehyung's soft hair.
Taehyung's soft murmurs and moans were rare in comparison to his own and as such Jungkook felt the drive to continue.
"Jungkookie" Taehyung warned, with his voice entirely heated and rough.
Jungkook took on the unspoken challenge and continued to raise the reaction. With a few soft caresses and strokes, Jungkook felt victorious. Taehyung's sounds were like music to Jungkook's ears. He could listen to them all night, and he felt a heated pool in his stomach.
Then a hot breath over his neck made him lose his grip.
"Ah-Taehyung!" Jungkook yelped out, but it was entirely too late. Sharp teeth bore themselves into the crook of Jungkook's sensation neck. Taehyung's teeth have bitten into the skin, hard.
Jungkook cried out and continued to breathe harshly. He was burning up from the sensation. It could have been due to his desire, and locked away fantasies but had Taehyung's eyes turned crimson then?
Flickering up at Jungkook, he found they were very much in their usual, and beautiful golden state. Jungkook was panting, entirely breathless and needy. It seemed Taehyung was taking a turn for the lead.
Taehyung's eyes shivered as he looked towards the very visible, and reddening love bite that followed. Jungkook wasn't exactly surprised by how hard that felt, but he couldn't voice anything now.
"Jungkookie, I-" Taehyung started out guiltily. 
He gently kissed and lapped at the love-induced wound. Had he lost control that easily? Marking Jungkook's beautiful skin had always been a pleasure, but to do that without warning.
