Justice League are a pack signed up for a pack omega breeding program.
Hal Jordan is an omega who registered in the air force on false documents, when his commanding officer found out he reported him, the court sentenced him to three sessions in the breeding program and then to be bonded to an alpha.
"Mr Jordan, a pack has chosen you for their next session. You might have heard of them, the Justice League. They are quite used to handling omegas like you." Nurse Alina told him as he tried pull his mind out of the drug induced haze.
"W-what??" he mumbled, his tongue refusing to cooperate.
"Doctor Brian has decided not to give you the six months training and has instead given you to a pack that specialises in taking in untrained omegas." Nurse Alina unhooked his IV and left.
After about 15 minutes when the drugs has almost completely worn off and Hal was struggling weakly against the restraints she came back in and starting taking his bed out of the room.
By the time Hal's head cleared completely and his limbs worked according to his will they had reached breeding room.
As the brightly lit room came into sight Hal struggled anew but the restraints held him in such a way that his arms and legs barely moved an inch.
Once the bed was in its right place Dr Brian silently started preparing an injection while the nurses hooked his legs in stirrups.
Hal's cries of protest and pain could be heard all the way down the hallway. Doctor and nurses left him alone once the procedure was completed.
Hal lay there motionless as Dr Brian's words echoed in his mind repeatedly, "It usually takes seven to eight hours for an omega to become pregnant, just in time for your new pack to come and pick you up."
He didn't know what happened in the next few hours, a few nurses came in once to change an IV and to tell him that he will not be having lunch as it was forbidden during the impregnation period for pack omegas, they mockingly told him that his next meal will be dinner which he will take with his new pack.
Hal remained quiet through their taunts, he then fell into restless sleep as whatever drugs they were pumping into him wouldn't let him sleep and the exhaustion of being in solitary confinement and being kept awake and hungry as punishment wouldn't let him stay awake.
He was pulled harshly from his sleep when a nurse jerked him awake and told him his pack was here, he undid Hal's restraints and helped him sit up.
The usually strong omega could barely remain upright and leaned heavily against the nurse who led him out into the visitors lounge. The nurse handed him over to an alpha who Hal assumed was the pack leader as there was only one woman accompanying him and she was also an alpha.
They led him out of the breeding home and into a car. By the documents in the woman's hand Hal assumed they had already been to Dr Brian's.
The ride home was spent in silence except for when the two alphas introduced themselves as Clark and Diana, what surprised Hal was that they were both pack alphas and that there was another pack alpha as well.
When they reached home which was a huge manor with a whole forest for a garden the alphas introduced him to another five people, Barry an omega and bondmate of Oliver an alpha and his wife Dinah a beta. J'onn an alpha from the nearly extinct species of Martialas and Arthur an alpha.
Apparently the rest of the pack was away on work or personal obligations, the members that were present treated him warmly except for J'onn whose species were known to be reserved in nature.
Hal tried to remain civil even though he didn't believe the sincerity of their warm welcome. At dinner the pack members told him about their occupations and asked him about his life, Hal revealed as little as possible while remaining polite.
The third alpha leader, Bruce remained absent. At about 9 Dinah showed him to his room and Hal fell asleep as soon as his head hit the pillow.
For the next three weeks pack members tried befriending him and involving him in household activities to settle him in, they ignored his sometimes rude behaviour.
Even though by now Hal was almost convinced they were genuinely nice people he still continued to form a plan in his mind to escape.
