Suddenly, ingesting human sperm is all the rage in the succubus world. Especially rare is "sperm whiter than white." That's right, it's called "silver sperm" because it's born from the brilliance of white. Yuuki, a hugely popular influencer in the succubus world, is always ahead of the trends. In order to ingest silver sperm, she disguises herself as a nurse and successfully infiltrates a hospital's urology department, a place full of dicks. She secretly seduces patients and extracts semen every day with semi-forced blowjobs, but she can't seem to find any silver sperm... (However, for some reason, the patients whose sperm has been extracted suddenly become energetic and are discharged one after another.) One day, while ingesting sperm from a patient as usual, Yuuki is seen in her succubus form by a young man from a pharmaceutical company. When her true identity is revealed, Yuuki tries to attack the young man, but... is it a premonition of love? Or a battle? Will Yuuki be able to find the silver sperm? Can the legendary sperm make these women say goodbye to their entire lives? This truly spectacular romantic story will make your heart skip a beat with its multi-layered structure that weaves together elements of suspense and comedy that would even surprise Hollywood! Starring Hiiragi Yuki shows off her erotic, punkish body and gives a great performance. The deep blowjob that resonates throughout the hospital and the intense, seductive spider cowgirl position are must-sees! In the end, it's just erotic. That's all. Original work: Kaipon Jiro.
