Designed for more advanced chastity play, this device not only will prevent your partner from completing a full, aroused erection, but the device includes a urethral insert. The flexible insert contours to the shape of the cock. There is also a thru-hole for urine or ejaculate. Note that the urethral insert can be removed, if you wish to not use it for a particular session. The device is made of stainless steel, making it non-porous, hygienic, easily sterilized, and temperature sensitive.
