My little sister wanted to take a bath with me for the first time in a while, so I reluctantly agreed. When we got into the bath together, I was surprised to see that her chest had started to develop! And what's more, that modest swelling was just my type—of course, it was a perfect strike! As I washed her body, I pathetically realized that I liked both her face and body too much, causing me to get super hard. Unable to hide it, she noticed, and I thought it was all over… but then, surprisingly, my sister was also feeling horny and came onto me! I couldn't hold back any longer, and it escalated into an incestuous taboo！！
