Ruri moved in with her stepfather ten years ago after her mother remarried. She quickly grew close to him, forming a bond like that of true parent and child. After their mother passed away five years later, her stepfather continued to care for her lovingly. One day, however, he seemed different than usual; he was secretly planning something. His plan? To claim Ruri's body as his own. "Your body belongs to me alone...," he whispered, caressing her now-grown breasts and ass before moving lower. There was no stopping the gears once they were set in motion. "No, please stop, Uncle! We can still go back... we can try again!" Was it love or lust driving him? All Ruri could do was accept his twisted actions, taking every creampie he gave her deep inside.
