The concept of "throat rape volunteering" refers to the act of selflessly offering one's throat to men who lack throat access, under the guise of social contribution. Tuna, the protagonist, visits a volunteer center to fulfill a childhood dream. However, she is deceived by the center's director, imprisoned, and subjected to throat violation●. Initially resisting fiercely, she gradually becomes accustomed to the dominant situation and submits completely. She endures various throat-focused acts—vomit spraying, deep-throat training using relief supplies, recycling irrumation involving enema-induced urine expulsion and forced drinking, vomit suction using hand cleaners, and irrumation service provided to men deprived of throat access—eventually seeking pleasure from them. Though Tuna feels her pure goodwill has been trampled, in reality, she possesses a strong masochistic desire to become an outlet for male lust. Her attitude reveals that "throat rape volunteering" was, in fact, the path through which she fulfills her own deepest desires.
