It would have made a better point if he didnt have a standing cock during the rape...
I mean i know what you're talking about. The author tried to make it smut with him starting to enjoy it at the end. Like this is how it works
Some Male rape victims do get an aroused not because of pressure but because of adrenaline rush that’s caused by fear. The best example I can compare this to is being tickled. Some people hate being tickled, myself included, so just because that person is laughing doesn’t mean they’re enjoying it. Though I don’t deny if the author will end the story with the priest kms or something else like you said in the second comment.
Don't having any problem with the religious themes in yaoi or straight smut stories, but this one makes me extremly uncorfortable.... Firstly because it's a pure rape story secondly, because they doing it most likely only to taint somebody whom they find just too pure.... Its disgusting.
