Concealed Stop Cock is an innovative product that can be used as a concealed cock ring or penis extender. The device has been designed to provide maximum pleasure during sexual intercourse. The device is made up of two parts: the base part and the cock ring. The base part is attached to the shaft of the penis while the cock ring is placed around the base part. The cock ring is then tightened to create a tight grip around the base part. This helps to prevent premature ejaculation and provides more control over your partner.
