To elaborate on Redskulr's wonderful description, every order of sex products on our market comes with a free trigger pussy. The trigger pussy allows you to add squirting, fingering, and cumming actions to any female avatar.
We also sell additional trigger pussies that can affect your butt size, add more definition / mound to the lips of your vagina, and allow you to spread your vagina's lips. These latter vaginas that cost money however .... are a bit buggy and can warp the skin around your thighs when combined with thigh scalers. Many modern avatars in IMVU's catalog come with built-in thigh scalers, so I would stick with the free vagina in most cases.
