〔Congratulations, for mating with a Queen Bee you got a new achievement: ”Not a virgin”! Your reward: “Drone Consort” title.〕‘Hey! I wasn’t a virgin before this, system!’Imagine that you lived a painfully average life, died by a stupid, stupid accident, but a goddess interfered and gave you a second chance in another world.There, you became a consort of a beautiful, big-chested queen, and your only job is to have mind-blowing sex with her so she could have thousands of your adorable daughters. In return, you can live in peace and luxury for the rest of your days.Which means, for about two months. Because I’m a bee. And my queen is also a bee. And bees don’t live for long.The only way to increase my lifespan is to develop my bee colony. A hard task in this huge world filled with dangerous and hungry beasts, other war-hungry insect tribes, and natural disasters.But I have a hundred thousand daughters, some actual brains, and with superior genes given to me by my system, we will be unstoppable!===Note: no NTR, harem, incest, or outright smut.

Because the thing living inside him 'The Echo' never sleeps.
