Donating blood is not the only form of community service!! In this day and age, we need not only blood but also semen!! This is the story of the struggles of four female volunteers from an organization that promotes semen donation!! In order to collect high-quality semen, veteran staff and new staff members all try their best to collect semen. They don't just use their hands and mouths to collect semen, they even use their own genitals to collect semen inside their vaginas!! Please watch them as they work hard to collect semen, suppressing their voices, not through sexual intercourse that makes them feel good, but simply as a means to collect semen!!
