Alien Seed Vault

Board the orbital thrill of Alien Seed Vault, a scorching sci-fi erotica standalone where humanity's last hope rests on one woman's body. When 24-year-old fertility specialist Nova is chosen for the ultimate compatibility trial aboard the Seed Vault station, she's claimed by five towering, marble-skinned alien donors engineered for one purpose: to breed her relentlessly. Zero-gravity knotting, glowing seed floods, and forced lactation under Earth's watchful cameras turn a clinical mission into an addictive reverse-harem harvest. Packed with extreme size play, public breeding kink, and futuristic milking, this is pure guilty-pleasure gold for fans of alien erotica and massive reverse-harem overload.
