Concubine Omega Tweek, in a world where large alpha houses operate like wolf or lion packs and you're under threat of getting destroyed or taken over by other houses constantly. Tweek isn't exactly thrilled by his lot in life, but he doesn't have a choice: house-less Omegas don't tend to last long. He's signing up to be bred, but Omegas adopted into houses are treated well and enjoy perks and protections he wouldn't get otherwise.
Group-sex-is-normal-here, Alphas are expected to share amongst their housemates ;) BONUS for Tweekship rarepairs, but I would kiss someone on the cheek for Tweekstophe, Creekenny or Twutters. :')
