みさおたんとあらいっこしよ

Wash your body with Misan tan....?
Misao is my cousin is here, haven't seen for 4 years. Her breasts are developing, but her innocence remains same, asking me to take bath together. Cannot stand for the seduction anymore, I and Misao begin to wash bodies each other while her parents are not home. It only escalates, something in myself triggered my sexual desire.....
