What is throat rape volunteering?: The act of voluntarily offering your throat free of charge to a dick that is not blessed with a throat pussy, in order to create a society where people can live together and help each other as human beings. "I want to be useful to society," Tsuna says, visiting a volunteer center to fulfill her childhood dream. However, she is deceived by the center's director, imprisoned, and throat-raped. At first, she resists strongly, but gradually she gives in. She vomits during a hard-core deep throating volunteer session, gets her throat trained with relief supply adult toys, gets forced to vomit during a piss-mouth enema deep throating session and then swallows it, gets hand cleaner shoved down her throat and sucks vomit, and gives deep throating service to men who are not blessed with deep throat pussies. Tsuna's throat is used however they want. While her pure feelings are violated, her true nature is that of a born masochistic volunteer who wants to be messed with, be an outlet for men's desires, and be useful for sexual relief.
