POSSESSION ✅

"So pretty, baby, doing so well for alpha," Jungkook groaned, slipping two fingers easily into Namjoon's slick heat beside his tongue. Namjoon had never been fingered before, his sexual experiences limited to toys. The stretch awakened something new within him, a desire that burned hotter than flames in his belly.

"Ah-ah, yes, more please alpha!" Namjoon cried out, words slurred as if a little delirious with the pleasure of it all, drunk on the feeling of finally being filled up. Jungkook scissored his fingers several more times for good measure before fulfilling Namjoon's request and slipping a third finger in beside the first two. He was being careful, but he knew Namjoon's body could take it- an omega in heat could take cock with little to no prep, bodies literally designed to be bred.

The thought had Jungkook pumping his fingers in and out of his brother's tight little hole like his life depended on it. He inserted his tongue alongside them to rile Joon up, making the younger boy jerk beneath him, getting him nice and wet for when Jungkook finally fucked him. He didn't want to waste any more time, wanted to finally make them one.

After briefly inserting a fourth finger just to double check that Namjoon was ready for him, Jungkook pulled out, causing an agonizingly pathetic noise to escape from Namjoon's throat at the emptiness. Jungkook made his way up the mattress, stroking at Joon's face and comforting him gently. "Shhhh, it's ok baby. Alpha's gonna fill you up, don't worry."

Jungkook placed his forearm on the mattress beside Namjoon's head, bracing himself as his other hand reached down to line his throbbing cock up with Namjoon's hole which was still furiously clenching around nothing. Jungkook hesitated momentarily- once he did this, there was no going back. But he couldn't think of anything he wanted more, just wanted to make his perfect baby brother his forever. Without another thought, he pressed his cock to Namjoon's rim and slid in.

Both boys gasped at the sensation, Jungkook pressing his forehead against Namjoon's as the two breathed each other's air. His breath came out as a low moan, reverberating off of Namjoon's skin as he pulled almost all the way back out before thrusting his hips forward again. Namjoon's body felt like fire around his, the tight wet heat overwhelming. Despite his strong alpha persona, Jungkook felt tears prickling in his eyes from how wonderful the sensation was.

Meanwhile, Namjoon was practically hyperventilating. His full lips were parted, so close to Jungkook's, as air was violently pushed and pulled in and out of his lungs. Jungkook took the opportunity to lick into Namjoon's mouth as he thrust in again, even deeper this time. Namjoon cried into his mouth, and Jungkook just swallowed down the delicious sounds and continued to pump his hips into his little brother. It was ecstacy and it felt so right.

Jungkook laid his full body against Namjoon's, flat plains of their abs sliding along each other on each subsequent thrust by Jungkook. Namjoon just lay there, caged in and lost to the pleasure. He had started whimpering against Jungkook's lips, and Jungkook pulled back slightly to observe his little brother.
