I have yet to see the corrupted Logan bottom for Ste. The closest thing to that was when the MC was panicking about Logan raping the son or something weird like that. It's been a while since I've read the scene.
If I remember correctly with arion you have a sexy scene pleasing vicoria, but a some time your sanity drops to five, vicoria want to imprison you but arion uses his big too to save you. If you are alone I think you're forced to fight losing likes but nothing too bad that affects future events. The scene is not as bad as recollected: you are afraid of the bad temperament of logan but when you arrive at the mansion logan is playing with the child. You see the possibility of him as a mentor and you think about the risk of the child to inherit both the bad temperament and the sluttines.
