DLDSS-447 Protect your egg from the sperm of those super stud old men with three condoms Chiharu Mitsuba

The most troublesome special creature in this world, the invincible old man. To counter his endless ejaculations, this time we will provide Miss Mitsuba with 3 condoms per old man. Please somehow keep the number of ejaculations within this range. If by any chance you run out of condoms, then it's straight to the egg cells with no protection. Please understand this in advance. Panicked Mitsuba hastily comes up with "strategies" to hold back ejaculation. What will become of Chiharu's egg cells.
