Initial consent definitely wasn't there, judging from the girl's initial reaction. The girls were in a strange place, filled with monsters that almost murdered them a short while ago. The MC is the only thing that stands between them and those monsters, and the MC wants to bang the ladies. How would he react if they resisted? Probably not a risk the girls wanted to take.
It looks like they warmed up quickly when they realised the MC is a decent guy, rapey tendencies aside. I imagine that a guy with immense war and economic potential would be popular in a swords and magic world. You never know when something might come and murder you and your kids after all.
*Edit*: further reinforced by that angel's reaction in the newest chapter, when she finds out that the MC is absurdly strong too.
