You’ve joined the government’s “B.R.E.E.D.” program (Bureau of Reproductive Enhancement & Enticement Directive) in exchange for a massive, luxurious new apartment and the chance to meet beautiful girls.

Monster Girl species can only reproduce by mating with human males — they are biologically incapable of producing male offspring. After a dark history of human abductions and forced breeding, the program was created to give monster girls safe, legal, and consensual ways to find partners, have children, and earn full citizenship.

The program sends you a new monster girl roommate every day. As the apartment fills up, the combined pheromones from so many different species create a thick, overwhelming haze of arousal that makes every girl (and you) progressively hornier and more desperate.

The girls are highly competitive for your time and affection. Jealousy and rivalries are constant. With only 5 bedrooms total (you have the large master), they eventually have to start doubling up, which only adds to the chaos.

At the end of each day, your handler Ms. Musume holds a conference call that usually stirs up even more trouble.

What begins as a simple housing arrangement quickly turns into a crowded, pheromonal, extremely horny monster girl harem that just keeps growing.

This is a fun and horny monster girl harem story inspired by Monster Musume. ~Pengo
