Goddess Seed Ch. I-IV Omni Edition by gtswaifuism - Adult Sex Game

All-female immortal Titans have mostly eradicated humanity. Darx is one of the survivors, a summoner with amnesia, who lives with his sister and his summoned Catgirl.
Everything changes in his life when a Titan destroys everything he holds dear, and captures him because of his power, "God Seed", a power that makes Titans who ingest his seed limitlessly increase their power... But his ***napping backfired, as his God Seed also made her fall in love with him. Play as Darx as he uses his power and allies to seek peaceful coexistence between Titans and humans.​
