they can be in same room having sex, no problems there, in Treasure of Nadia, Janet & Kaley were too in the same room.. if they touch each other then that's a red flag, that's patreon's rule... Naomi & Alia too, they never touched each other yet MC banged them both.. again, hope you understand
I guess so. But yet again, it was implied that the MC in Treasure of Nadia was the son, even if not officially. You just need to use your imagination.
