But even then, Ren told Aurora that he wanted the tell the other four ladies about this. And he had not made this decision without thinking.
In the near future, Ren was going to be adventuring with all of them and they would also face various dangers together.
For that reason it was important for then to know about what Ren was capable of doing. Or this would create confusion in critical situations and might endanger everyone's lives.
And most importantly, Ren trusted them. He was brought to this world by a summoning circle that the ladies had found during their adventuring. So by all means, he was something like their property.
Now Ren also knew that there were various kinds of enslavement spells and even items capable of doing the same thing.
So if the ladies wanted, they could have just make him their sex slave and force him to fuck them and only the people they approved continuously. That would have been the most optimal way to benefit from Ren's powers for the ladies.
