The most troublesome special creature in this world, the super-enduring old man. In order to counter his endless ejaculation, this time we will provide Ms. Mitsuha with 3 condoms per old man. Please try your best to suppress the number of ejaculations within this range. If you happen to use up all the condoms, you will then have to receive direct creampie into your egg cells without protection. Please understand this in advance. Anxious Mitsuha, hastily devised "plans to suppress ejaculation." What will be the fate of Chiharu's egg cells?
