"Hey, do you want to see your big sister naked?" With those words, the beautiful and pure Mishima Ryo suddenly appeared at my house. Checking in on me while I was home alone, she came to visit and played hide-and-seek with me in the bathroom and dark closets, giving me adult kisses and teaching me about a woman's body. Gently yet provocatively, she took my virgin cock into her—those moments felt like a dream.
