Breeding Season Estrus

Breeding Season Estrus is a free adult game and a very long labor of love. Have you ever stared up into the night sky and found yourself wondering what kind of sexy monstergirls/boys/enbies/energy beings are up there boning amongst the stars? Do you keep returning to thoughts like "I like Star Trek and all but why don’t they solve more problems by screwing?” Perhaps you too have found yourself asking the age-old question of "What if John Carpenter's The Thing was actually really hot and DTF?"
