World Isekai Red Eyes

You're the last man standing in a world where all other guys are limp-dicked babies. Chicks see you as their only chance to get pregnant. You gotta fuck a bunch of women to keep the human race alive. But be careful, because some ladies might try to trap you or kill you for your seed. Use your dick wisely and choose who to knock up. Fuck them all or find a keeper, but don't let this apocalypse fuck you over! Some women will worship you, others will hate you, and a few might even try to steal your sperm by force. It's a crazy world out there, so keep your guard up and your dick down... unless it's time to breed!
