Clockwork girl. She looks and acts like a real girl, but her clockwork heart goes tik-tok tik-tok just for you. Only for 48 hours though, so you need to wind her up regularly.
And to wind her up you have to pull down her panties and stick you manly "winding key" in her then grind it in roughly real good unit you spray "lubrication grease" deep in her gears for a nice smooth run.
She loves to get wound up by you!
