My sister, who lives alone in Tokyo, finally came back home! She's kind, smart, has big breasts, a great figure, and is cute... basically, she's my dream girl. No matter how much time passes, she still treats me like a kid and says "Let me wash your back" while trying to take a bath with me! I can't help but be distracted by her breasts as she forces me into the bath, and they keep brushing against my body, making me hard. Of course, she notices...
