A bedroom with the morning sun streaming in... One day, I woke up with a hangover and realized that a woman's hand was touching my body. Thinking it was my wife, I traced her hand and lifted the blanket to reveal an unbelievable sight. My wife's younger sister, Yuichan, who had been staying at our place for job hunting since yesterday, was sleeping naked! 'This is bad... This situation is way too messed up...' Somehow, I managed to get out of there without my wife noticing, but ever since then... Yuichan has been seducing me whenever my wife isn't looking.
