From JT's Stockroom:
The SiFeet Pussy Foot is the ultimate fantasy sex toy for foot fetishists. This size 6, 100% silicone foot is cast in pure silicone from a real life actual, beautiful female foot. In the sole of this lovely foot is a fully functional and totally fuck-able silicone vagina.
This pure silicone foot is soft, smooth, and incredibly sexy. The toes are decorated with acrylic toenails painted glossy pink, making the Pussy Foot seem even more real.
From the toes to the heel and ankle, great time and effort has been taken to insure that the Pussy Foot seems real.
From Wikipedia:
Like other paraphilias, foot fetishism encompasses a wide range of predilections; one foot fetishist may be aroused by scenarios that another fetishist finds unerotic or even repulsive. Websites exist that cater to a number of specialized scenarios, including: women walking barefoot in the street with dirty soles or on uncomfortable surfaces such as hot pavement, feet pushing down on gas or brake pedals, feet crushing objects like balloons or toy cars, feet being pushed into mud or food, female foot torture (i.e. having the soles of their feet tortured or punished by whippings, hot wax, burnt with cigarettes, etc. see bastinado and falaka.
