If you have a recent HFpatch, you have everything you need. At a minimum you need working better penetration mod and [Rikki Balboa] Anus v1.0.zipmod

how do i enable the sound ?? becouse i cant hear it

No sound was added, i don't do sound for most of my Scenes. Takes alot of time, usually sounds bad ( unless you use outside mods ).
