Cameras follow singer, dancer, model, variety personality, and porn star Nana Miho for an entire month, ambushing her between late-night television shoots, live-show rehearsals, and costume fittings. With no warning, a porn actor suddenly penetrates her and launches into relentless guerrilla sex. Afraid others nearby will hear, she suppresses her voice and silently cums while the pounding echoes around her. The result captures both her genuine private side and raw, unmistakable orgasms—and by the end, she seems hooked on the sudden surprise sex.
