We step-siblings got along quickly since we were close in age. Our relationship as three changed dramatically over the course of three days when our parents were away. The spring break, a time of changing seasons and environments, was too boring to spend lazily at home. "Big brother, you sometimes look at Ichika with lecherous eyes, don't you?" I was flustered, and suddenly she kissed me... Reason collapsed. Even when Kanna came back, my lust didn't stop. Influenced by us, even the serious Kanna started to demand it... We fucked like crazy.
