A meat man who visits brothels every payday decides to try something special this time—an exclusive 4P harem course from a delivery health service. He immediately calls the shop and is greeted by three big-titted women. They introduce themselves as Mizuki, Waka, and Riho, clearly ready to begin with an instant handjob service. To his surprise, the three reveal they work at the same place, making this first-time 4P experience feel like pure bliss. A few days later, complaining of poor health, he visits a hospital where three big-titted nurses wearing masks begin a mysterious seduction. What follows is an extraordinary crossover of experiences between brothel indulgence and hospital encounters, starring an insatiable meat man.
