SOS - Schlongs of Skyrim is a mod intended to work as a framework for customized, animated and dynamic assignment and management of male genitalia. Although the mod started by only aiming to provide it only for male characters, due to demand, it soon shifted to a full framework, capable of managing it to any possible race/gender. Currently it features a base male body to work with, and 3 distinct shape Addons. We expect with further development, to extend the shape "database".
My understanding is that not only does it add dicks, but you can control your character's dick with keybinds, because why the fuck not?
Evidently a large number of people were highly offended by this mod, because dicks are terrible but vaginas and gigantic boobies are perfectly ok.
THE VARIETY OF COCKS IS ASTOUNDING!!!!!
WHY DO I NOT HAVE THIS INSTALLED????
