J-Lube is a hand lubricant concentrate for the vetirinarian! It is an inexpensive concentrated lubricant sold in powder form. When mixed with water, J-Lube becomes very slick and slippery.
If you've never experienced J-Lube in person, you're in for quite a surprise! It is great for fisting or for playing with dildos, butt plugs, and any other large objects that bring you pleasure.
