When a masochistic man suffering from premature ejaculation consulted the kind-hearted Lauren Hana Koi, he received super positive advice such as, ``Your dick is not number one, it's your only one,'' and ``It's okay to ejaculate as many times as you like.'' Moreover, he also gave me practical training so that I can shoot unlimited semen! This is a documentary work in which 4 people in 3 groups ejaculate a total of 12 shots!
