regarding the whole wendy / netori debacle ( this will split opinions)
i think wendy going full slut mode does make sense to an extent... after all she's been in a shit marriage for god knows how long , no doubt there sex life was awful... now she's banged the mc and experienced good sex so why not let her go rogue and let her freak flag fly and see what freaky shit she wants to try with the mc in the future.... now i probably would of eased her into turbo slut mode rather than kick into a gangbang,circle jerk bukakke what ever that was situation
personally i think that outside of cindy it makes sense for other LI's to bang whoever or do whatever, like look at the mc realistically he's a dope that can't even tell when a woman is interested in him , so he's definitely not going to grasp the concept of what's going on or consider the possibility of taking these women as actual lovers unless cindy tells him to do so / that cindy explains that they are now his women and that he shouldn't let that happen
so all this completely fits with his character and lets not forget he wouldn't be banging anyone else if it wasn't for cindy , essentially she points him and his dick in the direction of other females and says go fuck her and he's like ok cindy
