This summer vacation, my girlfriend and I decided to visit her hometown. She had told me about this place, a small village with no convenience stores around, always giving a sense of boredom. But when we arrived, her parents were out of town, leaving only her older sister, Iroha, at home. She is truly beautiful, with pure white skin and seductive legs. I could hardly take my eyes off her. In the evening, the three of us slept together, her wearing a thin nightgown that allowed me to see her breasts peeking through. She noticed but instead of getting mad, she let me gaze and touch her breasts, and then allowed me to have sex with her!!! Since then, I no longer feel bored with this place. I always think of her in my mind. And whenever my girlfriend is away, we engage in sexual activities time after time...
