Riona, the queen of breeders known only to the initiated, rigorously trains male masochists every day to fully unlock their submissive genetic potential. Today, another new M-man arrives before Riona. Though he's still clumsy with his hands, he'll gradually improve—once he can endure having his feet licked, he'll eventually earn the right to climax on his own. And when that day comes, he must flood Riona's womb with abundant sperm. Because it's an order. Her drool drips onto his cock, while her slick, melting pussy awaits just ahead. Every M-man Riona raises will evolve into a perfected being, destined to pass on his genes completely.
