"If a long cock reaches all the way down my throat, that alone can make me cum." Thirty-one-year-old married beauty Yu Mito has a gorgeous figure and a secret extreme sensitivity deep in her throat. Unable to tell her serious husband that gentle marital sex no longer satisfies her—or that she wants her throat used until she nearly suffocates—she has lived an ordinary married life while frustration builds. Finally she enters the world of porn she has always watched, rejects tenderness, and fully unleashes the fetish she has hidden for years.
