@Rikunii while yes it was initiated by the omega, consent can be taken away at any time. He got scared and wanted to stop, and yes I know they technically couldn't stop, but it's not the omegas fault either. To the omega it's traumatic and his pheromones are pushing him to do it involving the alpha but when the omega becomes lucid he's terrified of what's going on and wants it to stop.
@Rikunii Just as @Luna Midnight said, consent can be taken away at any time. When the omega first initiated it, he was under the influence of both alchohol and heat, so he couldn't think straight so he didnt consiously give consent, but the alpha, knowing that, didn't hold back and technically r@ped him. It happened a second time when the omega woke up and was sober from his heat, he was trying to leave and get the alpha to pull out, but he forcefully r@ped him again even though the omega was showing clear signs of discomfort and fear. It may be the omega's fault for not taking suppressants, but it is ultimately the alpha's fault for being conscious, but still biting and fcking the omega without consent. Yes, the alpha may have been slightly affected by the omega's phermones, but he was still more lucid than the omega in both situations.
