The Frii Wilii Crotch Support | Counterpart Protection

The Frii Wilii utility patent provides a specially-designed frontal crotch support for Wilii's counterparts. This crotch support allows you to Frii Wilii without hurting yourself due to epidydimal hypertension, otherwise, known as “blue balls.” 

Epidydimal hypertension  can occur in males who "go commando" for extended periods of time.
