Your ass is really screwed, but in a good way, with the Tantus Twist Silicone Plug. It resembles a wine bottle corkscrew but in a bigger and less pointy way. The screw design brings on the pleasure as you feel the Twist bore into your bunghole. It does not go too deep with an insertable length of only 4 inches and it is not too difficult to plug in with a diameter only at 1.3 inches at the widest. Made from pure premium silicone.
