After my parents remarried, an incredibly cute little sister came into my life, and we started living together every day. I gradually became obsessed with her, unable to get her off my mind. Strangely, she seemed to have feelings for me too, and we secretly began a relationship. Though we usually just flirt and act affectionate in public, when our parents aren't home, we can't hold back our desires—our emotions surge uncontrollably. As time passes, our bond grows deeper and stronger. We always creampie her, connecting our feelings even more intensely with each release inside her.
