I totally get what you mean, and it made me a bit uncomfy as well. Yes, Cirrus did the aftercare and depending on your choices the MC can be totally into it. But the fact is just saying "no" and walking away isn't presented as an option in those scenes. The MC is in a situation where "no" means death in this situation. At no point does Cirrus give them a safe word and no sort of discussion about kinks and boundaries is had beforehand. None of this is okay in safe, responsible, and consensual BDSM. Plus it's all attached to a religion that the MC hasn't necessarily joined. And that's okay because this is just a game and not every relationship is sunshine and rainbows. But the consent in this situation is dubious at best, and Cirrus is by no standard a caring and responsible dom.
