All seven members of bts are brothers well kind of Jungkook is adopted and they are all aware of that including Jungkook and that doesn't make him feel any less loved than the others anyway they are a family of Alphas so what happens when Jungkook...
In this au world you find out your second gender a week after your 20th birthday and there are three options Alpha, Beta, or omegas , you determine this by a tattoo that appears on your neck , Alphas have a big pure black wolf , betas have medium sized brown wolves , omegas have a small pure white wolf , Alphas are the strongest and they are the most possessive, Alphas make up 30% of the population and 75% are males , betas are average in all aspects and make up 50% of the population also 50/50 of male and female, omegas are the weakest and need the most protection and attention and make up 20% of the population and only 15% are males so male omegas are pretty rare, mates also exist in this world and usually omegas mates are Alphas and they tend to have multiple , while betas usually have one and same for Alphas, also omegas once presented are sent straight into their first heat
In the this story I couldn't decide whether I wanted Jungkook to be an innocent baby bun or a sassy baddie so I decided a little bit of both so Jungkook will be aware of sexual things and how mating and stuff works but he's never experienced it so basically he's never been horny before or anything but despite that he's sassy and can be sexy and knows how to be so yeah.
Third Persons POV
It's been a week since Jungkook's 20th birthday and well he was in his bedroom mirror for the umpteenth time. He has been curious to what his second gender will be. He kind of had a guess though he knew he wasn't an Alpha considering his petite frame. He's 5'6 ( 167.64 cm) and has a thin waist, thick thighs and ass. Also barely any muscle and he looked quite delicate so he was guessing he's an omega. But he needs to see the tattoo to confirm it. So today he was fresh out the shower when he glanced at his neck in the mirror and he smiled widely as he saw the small white wolf tattoo there. Jimin owes him 5,000 dollars because his dumbass said he was going to be an Alpha. So Jungkook quickly got dressed in his night clothes.

He then ran out his room to the living room where all his adoptive brothers were. They were all Alphas and since he's been with them since he was 10 Jimin thought their Alpha genes would rub off on him. So right as he was about to go brag to Jimin he froze as all their scents hit him at once. They smelled really good like really good intoxicating almost. His body immediately started to heat up and the heat was the worst in his lower stomach. In a matter of seconds he felt a wet and kind of thick liquid run down his leg and his underwear were soaked. It was his slick to help prep for mating. Jungkook's heat was starting and he was well aware. He knew he should probably leave before he gets pounced on but he doesn't want to. They smell too good and they were all spread across the living room watching a movie. Namjoon and Hobi were on the floor, Taehyung and Jimin laying opposite to each other on the couch. Yoongi and Jin sitting in the two recliners. Jungkook came to the conclusion that they were his mates because all he wanted was to to get railed and he's never felt that way before. Also their scent was just too addicting to resist. An omega would usually be scared if in heat around Alphas that aren't their mates. So Jungkook got on the floor on his hands and knees and started crawling towards Namjoon and Hobi on the floor. They were all too engrossed in the movie to notice him plus it was dark and he's small and wearing black. Jungkook's mind was getting cloudier by the minute. Jungkook was closest to Hobi now and decided to pursue him first. He was right next to him when Hobi noticed him and smiled.
