The world has gone to hell, zombies are everywhere, but you have the ultimate trump card. Literally. A mysterious System has made your semen the sole salvation of humanity. The rule is simple: hook up with babes, drive them to wild orgasms, and the System upgrades your base and drops heavy buffs in return.

Assemble a squad of the juiciest surviving girls. Every single one of them craves your attention and your juice. One will go mow down mutants on the front lines after a wild night, another will run to speed up research, and a third will just give you an unforgettable marathon.

By day, you manage the bunker, upgrade the girls' guns, and send them on dangerous supply raids. By night, the walls of your shelter will be rocking from the moans. It is a wild mix of management, action, and an explicit adult novel where everything revolves around your manhood.

Scientists spent years looking for a vaccine, but your dick turned out to be the cure. The girls are already soaking wet and waiting for orders. Get in there and show them who is boss.
