One day, a succubus named Kururu arrived at my house—a girl with an honest, innocent charm. The perfect little devil, she declared she couldn't return home until she'd absorbed 2,000 ejaculations, and thus began living with me secretly, without my family knowing. From then on, each day became a repeat of creampie sex, blowjobs, and cum swallowing. At first, Kururu was nothing more than a being who took my sperm, but as time passed, she gradually became someone truly important to me. Through this, our bond grew deeper.
