I seem to remember there was a mod...

[OH1972]

...which allowed you to refuse to do Vulpes' bidding in Nipton, on which he would get less than amicable. Which mod is that?

Do you search this one? http://www.loverslab.com/files/file/290-twistedmindsesp/

It´s a small mod that lets you have or forces you   to have sex with Vulpes and the legionaires in Nipton.

Don´t know if it works with the new sexout ng and scr.
