I watched as Tsukasa got behind Gakita and mounted him. He did not need his hands to guide his dick to the Protector's asshole. The ronin grabbed the omega's hips. It was finally time to get the breeding started. Tsukasa's whole body shuddered as he thrust inside. He was not able to get all the way inside. Gakita looked over his right shoulder and smirked. "Are you even inside of me yet!? Get on with it already!" he teased the alpha. The whole mounting mini-game was 5 minutes. The practice mini-game was 10 minutes. That was because of the average length of sexual encounters worldwide in real life. "What sorcery is this!? Why is this omega so tight. No omega can resist an alpha's member." Tsukasa demanded. Gakita chuckled out loud. "I already told you! Your cock is too weak to breach me. If you were any weaker or I was any stronger, you wouldn't be able to get inside me at all!" he said smugly. Gakita was completely correct. Omegas and alphas operated on pheromones. Omegas had evolved to be more fertile and birth more, healthier children. They wanted worthy cum.
Getting that worthy cum was important. That was why beta male cum could not satisfy the breeding urge during a heat longer than an hour or so. It was also why all their internal hymens were found 8 inches in. Beta males had an average cock length of 7 inches. Even the really well endowed betas with 8 inches could only brush against it. Without breaching the hymen, the chance of pregnancy was 0%. Worthiness was based on the level disparity between an alpha an omega. Most alphas were stronger than omegas. Mechanically, alphas naturally gained double the exp. from tasks and combat as the other genders. Culturally, omegas and female betas were seen as weaker and fairer, so they were forced into submissive gender roles where they would not be racking up as much exp. Even if they broke the mold, they would still be outpaced by every alpha due to the disparity. When the omega was stronger, there were tiers based on by how much stronger the alpha was. If the omegas were 5 times stronger or not, the alpha would not be able to get inside. Pheromones would reject it.
Having an immunity to those pheromones, beta males would instantly bust a nut and be too overstimulated to continue. At 4 times the level of the alpha, the alpha would only get a quarter of his cock inside. He or she would have to work from there during the mini-game. Every stage passed would allow then to sink deeper into the omega male's ass or female's pussy. For females, the hymen was practically external. Even an omega male could breach an omega female. I knew that Tsukasa was level 13 from the reports given when engaging him. I wanted the members of the Maruyama Clan strong so I could use them as puppets. If he was the "ruler" I could have all the power here. Still, they would need to be strong warriors to help defend the area. If I gave him a concubine at level 100, it would be useless. They could be the most beautiful and fertile NPC in the world but, if Tsukasa could not even breach them, it would all go to waste. If 5 times was the absolute limit, that meant Gakita could not be level 65 or higher. Level 60 was fine. That was only 4 times stronger. He could get it in.
