Beak sheath

A Beak sheath is a fictional, hypothetical device for anthropomorphic avians. The device, as put forward by Nek0gami, would allow avians and other beaked individuals the ability to perform, among other activities, oral sex on another partner while reducing the chance of injury on a sexual partner's genitalia. The sheath would do so by covering the sharp serrations on the tomia on both the top and bottom beak with form-fitting polymer 'lips'.
