Magic Cow String (Patreon)

This is a special little mental cow transformation file. Whenever you  wear the trigger and masturbate, you will feel an incredible desire to  moo growing inside of you. With every second and every stroke it will  grow, and if you give in and moo you will slowly begin to transform into  a cow. You will feel your human mind melting away, replaced by a cow  mind. 

After you stop mooing and touching yourself you will slowly revert back to normal over the next 20 – 30 minutes.
